Volosovo hunter-gatherers started to disappear earlier than previously believed

Recent paper (behind paywall) Marmot incisors and bear tooth pendants in Volosovo hunter-gatherer burials. New radiocarbon and stable isotope data from the Sakhtysh complex, Upper-Volga region, by Macānea, Nordqvist, and Kostyleva, J. Archaeol. Sci. (2019) 26:101908.

Interesting excerpts (emphasis mine):

The Sakhtysh micro-region is located in the Volga-Oka interfluve, along the headwaters of the Koyka River in the Ivanovo Region, central European Russia (Fig. 1). The area has evidence of human habitation from the Early Mesolithic to the Iron Age, and includes altogether 11 long-term and seasonal settlements (Sakhtysh I–II, IIa, III–IV, VII–XI, XIV) and four artefact scatters (sites V–VI, XII–XIII), in addition to which burials have been detected at five sites (I–II, IIa, VII, VIII) (Kostyleva and Utkin, 2010). The locations have been known since the 1930s and intensively studied since the 1960s under the leadership of D.A. Kraynov, M.G. Zhilin, E.L. Kostyleva, and A.V. Utkin.

Sakhtysh II and IIa are the most extensively studied sites of the complex, with ca. 1500m2 and around 800m2 excavated, respectively. The burial grounds at both sites are considered as fully investigated.

Sakhtysh chronology

The AMS dates do not support the previously proposed phasing of the Sakhtysh burials to early (4750–4375 BP/3600–3000 cal BCE), late (or developed; 4375–4000 BP/3000–2500 cal BCE), and final (4000–3750 BP/2500–2200 cal BCE): the early and late burials at Sakhtysh IIa do not stand out as two separate groups, and also the burials and hoards from Sakhtysh II, connected to the final phase, are temporally overlapping with these. Neither the use sequence, where the settlement and burial phases are non-overlapping and also complementary between the sites (Kostyleva and Utkin, 2010, 2014), finds support in the present material.

The AMS datings indicate that the Volosovo people started to bury their dead at Sakhtysh IIa after 3700 cal BCE; dates earlier than this may be affected by FRE or suffer from mixed contexts and poor quality of dates. The present data questions the interpretation that the Sakhtysh IIa cemetery was used without interruptions between 4800 and 4080 BP (Kostyleva and Utkin, 2010), i.e. for a millennium between 3550 and 2600 cal BCE. The AMS dates rather suggest a use period of some centuries only around the mid-4th millennium cal BCE, tentatively 3650–3400 cal BCE. This would also be more realistic considering the number of burials at the site.

Volosovo chronology

The absolute dating of Volosovo culture was for a long time hampered by the small number of radiocarbon dates (see Kraynov, 1987). Today,>100 datings connected with it can be found in literature (Korolev and Shalapinin, 2010; Chernykh et al., 2011; Nikitin, 2012; Mosin et al., 2014). Unfortunately, the available dates do not form solid grounds for dating the cultural phenomenon, as many of them have quality-related issues, large measurement errors, and ambiguous cultural or physical contexts. Consequently, particular datings may be connected to different cultural phases by different scholars. Finally, a large part of the newly-published datings are obtained through direct dating of potsherds (Kovaliukh and Skripkin, 2007; Zaitseva et al., 2009), and therefore, their cogency must be faced with reservation (see Van der Plicht et al., 2016; Dolbunova et al., 2017).

The datings connected with Volosovo cover a wide time range between ca. 5500 BP (4400 cal BCE) and ca. 3700 BP (2100 cal BCE). However, datings from secure contexts, with good quality (error ca. 50 years or below) and no probable FRE, place the beginning of Volosovo culture to the first half of the 4th millennium cal BCE, around 3700–3600 cal BCE. This is also supported by the roughly coeval terminal dates given for the preceding Lyalovo (Zaretskaya and Kostyleva, 2011) and Volga-Kama cultures (Lychagina, 2018), as well as the appearance of related neighbouring cultures, for example, in the Kama region (Nikitin, 2012; Lychagina, 2018), the southern forest steppe area (Korolev and Shalapinin, 2014), and north-western Russia and Finland (Nordqvist, 2018). Still, the dating of many of these cultural phases suffers from the same problems as of Volosovo.

A handful of contested datings place the end of Volosovo culture to the final centuries of the 3rd millennium cal BCE, or even later (Kostyleva and Utkin, 2010; Chernykh et al., 2011; Nikitin, 2012). On the other hand, the new AMS dates indicate that Volosovo activities at Sakhtysh II and IIa ceased before or towards the early 3rd millennium cal BCE; if this reflects the general decline of Volosovo culture must be still confirmed by more dates from Sakhtysh and elsewhere. In this context, the general cultural development must be accounted for. To what extent – if at all – the Volosovo people were present after the arrival of the Corded Ware culture-related Fatyanovo-Balanovo populations? Based on the current, albeit scant and inconclusive radiocarbon data this took place from ca. 2700 cal BCE onwards (Krenke et al., 2013).

Comments

One of the interesting genetic papers in the near future will be the one that finally includes samples from Corded Ware groups in the forest zone (i.e. Fatyanovo-Balanovo and Abashevo), which will most likely confirm that they are the origin of the known genetic profile of Central and East Uralic-speaking peoples, seeing how West Uralic peoples show genetic continuity in the East Baltic area, coinciding with the Battle Axe culture.

Uralicists have come a long way from the 1990s, when the picture of Uralic before Balto-Slavic in the Baltic was already evident, and Uralians were identified with Comb Ware peoples. The linguistic data and relative chronology are still valid, despite the now outdated interpretations of absolute archaeological chronology, as happens with interpretations of Krahe or Villar about Old European.

As an example, here are some relevant excerpts from Languages in the Prehistoric Baltic Sea Region, by Kallio (2003):

NOTE. Kallio’s contribution appeared in the book Languages in Prehistoric Europe (2003), which I hold nostalgically close in my Indo-European library (now almost impossible to read fully). It is still one of my preferred books (from those made up of mostly unconnected chunks on European linguistic prehistory), because it contains Oettinger’s essential update of North-West Indo-European common vocabulary, which led us indirectly to our Modern Indo-European project from 2005 on.

In any case, the Uralic arrival in the region east of the Baltic Sea preceded the Indo-European one (…).

This theory that the ancestors of Finno-Saamic speakers arrived in the Baltic Sea region earlier than those of Balto-Slavic speakers is still rejected by some scholars (e.g. Napolskikh 1993: 41-44), who claim, for instance, that Finno-Saamic speakers would not have known salmons before they met Balts because the Finno-Saamic word for ‘salmon’ (i.e. *losi) is a borrowing from Baltic. Similarly, one could claim that English speakers would not have known salmons before they met Frenchmen because English salmon is a borrowing from French. In other words, Worter und Sachen are not necessarily borrowed hand in hand. Otherwise, it would not be so easy to explain how many Finnish names of body parts are borrowings from Baltic (e.g. hammas ‘tooth’, kaula ‘neck’, reisi ‘thigh’) and from Germanic (e.g. hartia ‘shoulder’, lantio ‘loin’, maha ‘stomach’).

A more probative argument is the fact that Balto-Slavic features in Finno-Saamic are mostly lexical ones (i.e. typical superstrate features), where Finno-Saamic features in Balto-Slavic are mostly non-lexical ones (i.e. typical substrate features). Note that there are more Balto-Slavic features in Finnic than in Saamic and more Finno-Saamic features in Baltic than in Slavic. This fact could be explained by presuming that Pre-Saamic was spoken north of the Corded Ware area and Pre-Slavic was spoken south of the Typical Pit-Comb Ware area, whereas Pre-Finnic and Pre-Baltic alone were spoken in the area, where both the Typical Pit-Comb Ware culture (ca. 4000-3600 BC) and the Corded Ware culture (ca. 3200-2300 BC) were situated. This area was most probably bilingual, until Finnic and Baltic won in the north and in the south, respectively.

As is well-known, the idea of Uralic substrate features in Balto-Slavic is not new (cf. e.g. Pokorny 1936/1968: 181-185). As recent studies (e.g. Bednarczuk 1997) have shown, their density is the most remarkable in the four Balto-Slavic languages spoken in the earlier Pit-Comb Ware area (i.e. Latvian, Lithuanian, Belorussian, Russian). On the other hand, occasional Uralisms in the other Balto-Slavic languages spoken west of the Vistula and south of the Pripyat may rather be considered adstrate features spread from the northeast.

comb-ware-uralic
Our beliefs from the 2000s. A hypothetic Uralic Comb Ware distribution before the arrival of a hypothetic North-West Indo-European-speaking Corded Ware. “Generalized distribution of the Pit-Comb Ware cultural complex (Mallory & Adams 1997: 430, Carpelan 1999: 257) and the most probable homelands of Saamic, Finnic, Mordvin, Mari, and Permic.”

The idea of Indo-European superstrate features in Finnic is not new either (cf. e.g. Posti 1953). As Jorma Koivulehto (1983) has recently shown, the earliest Indo-European loanword stratum in the westernmost Uralic branches alone can be considered Northwest Indo-European and connected with the Corded Ware culture (ca. 3200-2300 BC). Since this layer, there have been continuous contacts between Baltic and Finnic. According to Koivulehto (1990), the following stratum can be called Proto-Balt(o-Slav)ic and dated to the Late Neolithic period (ca. 2300-1500 BC). Note that this Proto-Balt(o-Slav)ic dating agrees with the established ones (cf. e.g. Shevelov 1964: 613-614, Kortlandt 1982: 181), when we remember the fact that archaeologists have also moved their datings back by centuries during the last decades.

Finally, there is also a Baltic loanword stratum which was not borrowed from the ancestral stage of Latvian, Lithuanian and/or Old Prussian but from some extinct Baltic language or dialect (Nieminen 1957). However, as these words still go back to the early Proto-Finnic stage, they can hardly be dated later than Bronze-Age ( ca. 1500-500 BC). Therefore, we may conclude that they were probably borrowed from a Baltic superstrate, which arrived in the Finnish Gulf area during the Corded Ware period and survived there until the Bronze Age, when it was no longer identical with other Baltic dialects. In any case, as later Baltic loanword strata concern southern Finnic languages alone, we may presume that this ‘North Baltic’superstrate had become extinct.

The traditional association of Uralic with Volosovo hunter-gatherers doesn’t make sense, since they neither miraculously survived for thousands of years nor mixed for hundreds of years with Corded Ware peoples, so we can now more confidently reject the recent assumption by Carpelan & Parpola that their language was adopted by incoming Fatyanovo, Balanovo and Abashevo groups, to develop into the known Uralic languages (more here). This includes one of the many models of the the Copenhagen group, who simplistically follow “Steppe ancestry” for Indo-Europeannes.

If one combines the known relative linguistic chronology with the North-West Indo-European hydrotoponymy layer, now more clearly identified as Old Europeans expanding with East Bell Beakers and derived Early Bronze Age groups, I think there is little space left for maneuvering out of the overwhelming evidence for a Uralic homeland in the forest-steppes, linked to the spread of late Sredni Stog/Corded Ware ancestry into north-eastern Europe and beyond the Urals.

Genetic continuity among Uralic-speaking cultures in north-eastern Europe

east-europe-bronze-age

The recent study of Estonian Late Bronze Age/Iron Age samples has shown, as expected, large genetic continuity of Corded Ware populations in the East Baltic area, where West Uralic is known to have been spoken since at least the Early Bronze Age.

The most interesting news was that, unexpectedly for many, the impact of “Siberian ancestry” (whatever that actually means) was small, slow, and gradual, with slight increases found up to the Middle Ages, compatible with multiple contact events in north-eastern Europe. Haplogroup N became prevalent among Finnic populations only through late bottlenecks, as research of modern populations have long suggested, and as ancient DNA research hinted since at least 2015.

I risked to correlate the arrival of chiefs from the south-west with the infiltration of N1c-VL29 subclades during the transition to the Iron Age, coupled with that minimal “Siberian” ancestry (see e.g. here and here). Now we know that the penetration of this non-CW ancestry started, as predicted, in the Iron Age; that it was highly variable in the few samples where it appeared, with ca. 1-4%, while most Iron Age individuals show 0%; and that it was not especially linked to individuals of N1c-Vl29 lineages.

It is also basically confirmed, based on the (ancient and Modern Swedish) N1c-L550 subclades found among Iron Age Estonians, that N1c-VL29 lineages and the so-called “Siberian” ancestry will be found simultaneously around the Baltic coastal areas, and that different lineages must have suffered later founder effects among Finns, which suggests that these alliances through exogamy brought exactly as much language change in Sweden, Lithuania, or Poland, as they did in the East Baltic region…

On the other hand, the paper has also shown a potential movement of Corded Ware-derived peoples, if the change from LBA to IA samples is meaningful; in fact, even more Corded Ware-like than Baltic and Estonian BA populations. The exact origin of that movement is difficult to pinpoint, and it may not be related to the arrival of Akozino warrior-traders from the south-east, since theirs seems to be a minor impact proper of elites in a chiefdom system around the Baltic.

Tentative area of most intensive contacts between Baltic and Balto-Finnic communities marked with a dashed line. Image modified from (Lang 2016).

Also suggesting a potential movement is the ‘southern’ shift observed in the West and East Baltic areas, likely showing the arrival of Proto-East Baltic speakers (such as the Trzciniec outlier), as we have already discussed in this blog. The unexpected increase in Corded Ware-like ancestry in the Eastern Baltic, coupled with the expected large continuity of hg. R1a-Z283 in the homeland of Balto-Finnic expansions, gives even more support to the known complex system of exogamy along the Baltic coasts, and offers another potential reason for the rise of Baltic-speaking territories in the West Baltic: elite domination.

It is nevertheless important to understand that, even among the most “genetic continuous” regions like Estonia, not a single population in Europe is heir of some ancestral, immutable people. Not in terms of haplogroups, and not in terms of admixture. Balto-Finnic speakers, however continuous they might seem (e.g. in Southern Estonians) aren’t an exception.

After all, this blog was (re)born to fight the currently prevalent sheer stupidity surrounding the simplistic “R1a/steppe ancestry=Indo-European” association, so I wouldn’t like to see it replaced with some other stupid continuity or purity ideas within 10 to 20 years…

Late Uralic stems from East Corded Ware groups

With the currently available tools – linguistics, archaeology, and now genetics -, I don’t think there is any argument to date to question the direct connection of the Late Proto-Uralic expansion with all Eastern Corded Ware groups (i.e. Battle Axe, Fatyanovo-Balanovo, and Abashevo), and thus at least with the unifying A-horizon of Corded Ware and the bottlenecks under R1a-Z645.

NOTE. The only out-group among Corded Ware cultures is the Single Grave culture. It appears to be an early Corded Ware offshoot, reflected in their non-unitary cultural traits (distinct from later unifying waves), in their varied patrilineal clans, and in the short-lasting cultural effect in northern Europe before their complete demise under pressure of expanding Yamna/Bell Beaker peoples from the Danube. The culture’s minimal (if any) effects on succeeding peoples might be seen mostly in the (mainly phonetic) Uralic substrate found in Balto-Slavic – although this may also stem from a more eastern influence, close to the Baltic – and in the contacts of Celtic with Uralic. The huge time depth between this early hypothetic Uralic layer in northern Europe and the emergence of peoples inhabiting these territories in recorded history have no doubt been erroneously interpreted as a lack of Uralic presence in the area.

1) That connection was evident in the Yamna – CWC differences in archaeology, and especially later, with at least Fatyanovo-Balanovo and Abashevo representing the obvious replacement of the Volosovo culture before further expansions of CWC-related groups west and east of the Urals.

The mythical millennia-long continuity of Volosovo hunter-gatherers, including centuries among Corded Ware peoples, as expected lately by the Copenhagen group (and anyone who doesn’t want to question the 1960s association of Indo-European with CWC) must be rejected today in population genomics, as the recent studies of ancient and modern populations show, and as ancient DNA from the region will confirm.

2) In linguistics, the survival of Volosovo as The Uralic-speaking culture was also hardly believable. From Kallio (2015):

While we can say at least something about Uralic substrates in Northeastern Europe, non-Uralic substrates cannot at all easily be identified, because of multiple language shifts, viz. first from non-Uralic to Uralic and then from Uralic to Russian. Yet the Soviet Uralicist Boris Serebrennikov (1956, 1959) argued that there are some non-Uralic substrate toponyms in the Volga-Oka region, but his idea was never taken seriously in the west (cf. Sauvageot 1958), and it pretty soon also sank into oblivion in Russia, even though it can still occasionally pop up there in non-onomastic circles (cf. Napolskikh 1995: 18–19). However, not all the hypotheses on non-Uralic substrates in Northeastern Europe should be rejected (see e.g. Helimski 2001b).

bronze-age-early-languages-east-europe
Tentative map of the distribution of known languages in Eastern Europe during the Early Bronze Age. See full map.

Helimski (2001) argues for a non-Uralic topo-hydronomy in Northern Russia, whose population may have kept their languages up to the Common Era despite the Corded Ware expansion, which is in line with the survival of some non-Indo-European languages everywhere in Europe after the expansion of Yamna and its offshoots:

It should be borne in mind that these [Uralic] hydronyms reached us mainly through Northern Russian and, accordingly, with a tendency to phonetic-morphological adaptation and unification (for river names it is “natural” to be, like the word ‘river’ itself, feminine and to end in -a). Taking into account this circumstance, it may turn out to be non-useless for etymological identification of at least some of the hydronyms on the Finno-Ugric basis.

On the other hand, I wouldn’t exclude the possibility that some parts of this large geographical area were never (completely) Finno-Ugric. The population that created the most important part of the hydronymy of the Russian North could be finally pushed aside or assimilated only at the end of the 1st – beginning of the 2nd millennium AD, during the Russian colonization, retaining the memory of the White-Eyed Chude in its own memory.

NOTE. For more on this non-IE substrate in (especially West) Uralic, see e.g. Zhivlov (2015),

The same non-Uralic substrate is most likely behind most of the shared traits by Mordvinic and Balto-Finnic (see below).

3) In genetics, I don’t think the picture could get any clearer. I don’t know what “Steppe ancestry = Indo-European” proponents expected from 2019, if they expected anything at all (I haven’t seen any coherent model, proposal, or prediction for a long time now), but I doubt the recent results are compatible with any of their implied expectations.

corded-ware-pca-sub-neolithic-europe
Detail of the PCA of the Corded Ware expansion. See full PCA and more related files.

Notice, from the PCA above, how this Baltic Late Neolithic group shows actually a shift from Sredni Stog (see PCA with Sredni Stog) towards typical Khvalynsk-Urals-related ancestry, i.e. populations from eastern European forested regions, derived from hunter-gatherer pottery groups, as I have proposed for a very long time, since the first time a Baltic LN “outlier” appeared. It’s amazing how some amateurs can find 0.1% of any Siberian outlier’s ancestry among Uralians 4,000 years later, but fail to see the direct connection here. The esoteric uses of qpAdm, I guess…

Especially noticeable is the extra WHG-like ancestry and corresponding shift, seen especially marked in late Polish CWC samples, but also in Baltic CWC and especially in one Sweden Battle Axe sample, all of them shifting apparently closer to Pitted Ware and SHG. While that may have been interpreted as an in situ admixture in Scandinavia before, the late Polish CWC samples show likely a resurgence of local populations, so we can assume that both shifts (to SHG- and EHG-like populations) of available CWC samples around the Baltic are clearly part of the WHG:EHG continuum that will be found in the eastern European sub-Neolithic cultures, from Narva to Volosovo.

This WHG-related ancestry is clearly predominant in groups with which Battle Axe peoples admixed, based on the shift towards Pitted Ware, which – I can only guess based on modern Volga Finns – is different from the shift we will see in Netted Ware, more towards the Khvalynsk-Urals cluster. This is in line with the expansion of Battle Axe eastward through coastal areas (West to East Baltic and Finland into Sweden), while Fatyanovo peoples probably emerged from a slightly different route, but also a northern one, if one is to follow archaological similarities and their chronology.

bronze-age-europe-baltic
Detail of the PCA of European Bronze Age populations. See full PCA and more related files.

During the Iron Age, the only peoples that probably shifted strongly (based on modern populations) are West Baltic ones, getting closer to the available Late Trzciniec samples, and even closer to the Trzciniec outlier, i.e. away from the earlier Eastern Corded Ware cluster, and towards Central European groups like Czech EBA or Poland EBA, both of them clearly derived from Bell Beakers, but also admixed with (and thus shifted toward) CW-like populations.

If one looks carefully at the previous PCA on Bronze Age populations, and the next one on Iron Age clusters, it is evident that adding the Swedish LN outlier to East Baltic BA (both strongly related to Battle Axe populations) essentially gives us the continuity of East Baltic BA into the Iron Age. This cluster is continued also in two outliers from Sigtuna, a Viking town close to the Gulf of Finland, known to be an important trading site, 1,500 years later. Not much of a change around the Gulf of Finland, then:

Based on the two simplistic Uralic clines one might see described (among the many that certainly existed, from Corded Ware to different Eurasian populations), and just like BOO was for some months fashionable as “Samic”, some may be tempted to say that certain Sintashta or Srubna outliers close to the Urals mark the True Uralic™ peoples. Because, of course they do. Ghost haplogroup N and stuff. And Corded Ware never ever Uralic. Because Gimbutas, and my IE R1a grandfather.

NOTE. Funny thing here: there might be Corded Ware, Iranian, Slavic, Germanic, etc… outliers or out-groups, and they might form the widest genetic clusters ever seen, but they are all of one language, because archaeology and linguistics; however, one “outlier” (also, put your own definition of “outlier” here, let’s say 1% of whatever, and strontium isotope potentially from 100 km away) ca. 600 BC in the Baltic who (surprise!) happens to show hg. N, and he signals the first incoming True Uralic™ speaker from wherever… It won’t be the first or the last time some people resort to “the complexity of Uralic-speaking peoples” in ancestry, just to look for “hg. N = Uralic” like crazy. You only need common sense to understand that this is not how this works. Amateur genomics can’t get more embarrassing than the current “let’s look for ‘Siberian ancestry’ in every individual of haplogroup N” trend. Or maybe it can, and it will, but I can’t see it yet.

If one were to insist on looking for ‘foreign’ contributions among Iron Age Estonians, though, I think one should also check out first archaeology, and then the PC3 (or, more graphically, a 3D plot), to understand what might be happening with the many Uralic clines derived from Corded Ware, before starting to play around with bioinformatic tools to discover a teeny tiny 1% admixture of the wrong population, and rushing to build far-fetched narratives. Apparently, one of the different clines formed roughly between southern (steppe – forest-steppe) and northern (tundra-taiga) populations in Uralians is also seen in some Iron Age Estonian individuals – especially in some late samples from Ingria…This is not my main interest, so I will leave this here for others to keep wasting their time chasing the white whale of the 0.5% of True Uralic™ ancestry in ancient Baltic samples of hg. N.

An exclusive Volga-Kama homeland for Disintegrating Uralic?

Since I don’t believe in macro-regions of largely continuous ethnolinguistic communities, as I have often said about Slavic (naively associated with prehistoric tribes of Eastern Europe) or Germanic (absurdly considered to be represented by Battle Axe), it is difficult for me to believe that Battle Axe-derived cultures remained of the same Finno-Samic dialects since the Corded Ware expansion…unless we live in Westeros, where everything happens “for thousands of years”.

I have to admit, then, that the now prevalent identification among Uralicists has become quite attractive:

  • Fatyanovo-Balanovo as Finno-Permic:
    • Fatyanovo/Netted Ware with West Uralic (also called Finno-Mordvinic).
    • Balanovo/Chirkovo-Kazan with Central Uralic (Mari-Permic).
  • Abashevo, into the Andronovo-like Horizon through the Seima-Turbino phenomenon, with East Uralic (also Ugro-Samoyedic).

Exactly like the identification of Yamna Hungary – Bell Beaker transition as the North-West Indo-European homeland, it gives us simplicity and small and late ethnolinguistic communities, away from the traditionally overused big and early language territories.

This late homeland would be supported, among others, by:

  • The presence of Indo-Iranian loanwords in Finno-Permic and Ugric (probably also in Samoyedic, either lost, or – much more likely – underresearched), compatible with the immediate contact between Abashevo – Sintashta-Potapovka-Filatovka and Fatyanovo-Balanovo.
  • The supposed expansion of Netted Ware from Fatyanovo to the north-west, which may be explained as the split and expansion of Balto-Finnic and Samic ca. 1900 BC.
  • A longer-lasting Finno-Permic (West+Central Uralic) community contrasting with the early separation of East Uralic.
  • The compatibility of this late expansion with the late expansion of Pre-Germanic from Denmark with the Dagger Period, and of Balto-Slavic with Trzciniec, which puts all three dialects reaching the Baltic Sea in the EBA.

NOTE. I meant to update the linguistic text to include the most recently favoured phylogenetic tree of Uralic languages after Häkkinen (2007, 2009, 2014), which has very quickly become the new normal among Uralicists, but I don’t think I will have enough time to review the necessary papers for that. I am rushing to publish a printed edition, so the text will wind up being a mixture of “traditional” (meaning, basically, pre-2010s) description of Uralic dialects but using modern divisions; say, “West Uralic” instead of “Finno-Samic”. By the way, I am still amazed that none of my reader-haters (or any online user discussing Uralic migrations, for that matter) have come up with the questions that the new division pose, and it supports my suspicion about the complete lack of interest in linguistics of most (a)DNA fans, except for the occasional use of old and free PDFs Googled to support new narratives invented expressly for some qpAdm results…

textile-ceramics-europe-bronze-age
Textile ceramic styles and influence of Bronze Age cultures divided in clusters.

Problems with this Parpola-Carpelan’s (2012-2018) interpretation include:

  • The differentiation between Fennoscandian Textile Ceramics vs. Netted Ware, which is not warranted in archaeology. The assumption that Netted Ware expanded to the Baltic Sea (as Kallio does, following the traditional view) is thus weak, and it was probably a question of cultural contacts coupled with short-distance population movements/exchange in both directions (from the Baltic to the Volga and vice versa). In fact, the culture division relies on some fairly common and technically simple ornamentation patterns, widespread all over northern Europe, even before the Corded Ware expansion, and it is very difficult to separate certain neighboring Textile Ceramics from Netted Ware groups in southern Finland (i.e. Sarsa-Tomitsa groups).
  • The strict and radical direction described for the Netted Ware by Carpelan, as an eastward and northward expansion, within a very short time frame (ca. 1900-1800 BC), based on few radiocarbon dates, which seems to me like a very risky assumption. We know how this kind of descriptions of direction of culture expansion based on radiocarbon dates has turned out in much more complex “packages”, like the Bell Beaker culture… In fact, the earliest dates for Textile Ware are from the East Baltic, earlier than those of Netted Ware.
  • The assumption that Balto-Finnic traits shared with Mordvinic are a) late and b) meaningful for dialectalization of two closely related dialects, when it is clear that both dialects separated quite early. Phonologically Finnic is more conservative, morphologically less so, and the shared traits include a handful of non-Uralic substrate words which can’t be traced to a single common source, hence they were adopted when both languages had already separated… All in all, Finnic – Mordvinic correspondances are not even close to Italo-Celtic ones, which is clearly fully incompatible with a proposal of a Finnic separation from Mordvinic coinciding with the LBA-IA transition.

Especially problematic for Parpola’s model is the lack of genetic impact in Bronze Age or Iron Age Estonians, not reaching a significant level under any possible statistical threshold – which I am sure was quite disappointing for some of my readers -, but is in line with major archaeological continuity of groups the from region, only disturbed in cultural (and Y-chromosome) terms by the expansion of Akozino warrior-traders all over the Baltic Sea. Any proposed population movement will be very difficult to support in genetics, given the Corded Ware-derived populations that we will see in both regions, and the continued Baltic-Volga contacts since the Corded Ware expansion.

Problems with an interpretation of such a small impact in population genomics includes the similarly weak impacts and haplogroup infiltrations that can be seen among populations basically everywhere in Eurasia, during any given period, and much greater genetic impacts that are supposed to be (or that were certainly) followed by ethnolinguistic continuity.

The Battle Axe question

From Kallio (2015), about choosing a tentative homeland for Proto-Uralic:

(…) linguistically uniform Proto-Uralic would have been spoken in the Volga-Oka region until the mid-third millennium BC when the Proto-Uralic-speaking area would have expanded to the Volga-Kama region as well. By the end of the same millennium, this expansion would have led to the earliest dialectal splits within Uralic into Finno-Mordvin, Mari-Permic, and Ugro-Samoyed. The splitting up of these three soon followed during the early second millennium BC when the Uralic-speaking area finally stretched from the Baltic Sea in the west to the Altai mountains in the east. Indeed, no matter where Proto-Uralic was spoken, the branching into the nine well-attested subgroups (viz. Finnic, Saami, Mordvin, Mari, Permic, Hungarian, Mansi, Khanty, and Samoyed) must have taken less than a millennium, because their shared phonological and morphosyntactic isoglosses are rather limited (see Salminen 2002). The traditional view that all this branching would have taken several millennia violates everything linguistic typology teaches us about the rate of language change.

The basic problem of this identification of Fatyanovo-Balanovo as West-Central Uralic and Abashevo as East Uralic is the nature of the Battle Axe culture, including the Bronze Age East Baltic and Gulf of Finland area. Even if it is accepted that Fatyanovo-Balanovo represented all Western groups, Battle Axe must have represented West Uralic-like dialects.

The ethnolinguistic identification of Battle Axe depends ultimately on the nature of contacts of Fatyanovo/Netted Ware with Battle Axe/Textile Ceramics. If both groups were close and interacted profusely, as it seems, it doesn’t seem granted that we will be able to distinguish a close Para-West Uralic dialect of Scandinavia from the actual expanding Balto-Finnic and Samic dialects, if they were actually linked to the Netted Ware expansion. Also from Kallio (2015):

No doubt the most convincing substrate theory has recently been put forward by the Saami Uralicist Ante Aikio (2004), who has not only rehabilitated but also improved the old idea of a non-Uralic substrate in Saami. His study shows that there were still non-Uralic languages spoken in Northern Fennoscandia as recently as the first millennium AD. Most of all, they were not only genetically non-Uralic but also typologically non-Uralic-looking, bearing a closer resemblance to the so-called Palaeo-European substrates (for which see e.g. Schrijver 2001; Vennemann 2003).

In comparison, the case of Finnic is much more difficult. The fact that Proto-Uralic was not spoken in the East Baltic region means that this area must have originally been non-Uralic-speaking, but so far the evidence for a non-Uralic substrate in Finnic has consisted of appellatives and proper names with no etymology (cf. Ariste 1971; Saarikivi 2004a). Contrary to the proposed substrate words in Saami, those in Finnic show no structural non-Uralisms, as if they had indeed been borrowed from some genetically related or at least typologically similar languages, as I suggested above. Also none of them is more recent than the Middle Proto-Finnic stage, which makes them at least two millennia old. All this agrees with archaeological evidence discussed earlier that the Uralicization of the East Baltic region occurred during the Bronze Age (ca. 1900–500 BC).

The discussion of the paper continues with an unsuccessful attempt to find a hypothetical ancient Indo-European substrate that Kallio believes must be associated with the expansion of Corded Ware, in line with the traditional belief. For example, the often mentioned – almost folk etymology-like, unsurprisingly popular among amateurs – ‘Neva’ as derived from IE “young” is logically rejected…Unlike Parpola, Kallio’s view seems to be confident that Netted Ware (as Textile Ware) expanded into the East Baltic, on both sides of the Gulf of Finland, already during the Bronze Age.

As it has become apparent in population genomics, none of them was right, and Textile Ceramics will essentially show – like Netted Ware – a large genetic continuity of Corded Ware peoples in the whole north-eastern European forest zone – despite small regional population movements, obviously -, which necessarily implies that the whole Corded Ware culture – and not only Fatyanovo-Balanovo and Abashevo – were Uralic-speaking territories.

The similarities in terms of culture and Y-DNA bottlenecks between Battle Axe and Fatyanovo-Balanovo also imply that the linguistic differences between these groups were probably not many, and became strongly divided only after their territorial division. Continued contacts between Battle Axe- and Fatyanovo-derived groups can explain the proposed contacts (Finnic with Samic, Finnic with Mordvinic) after their linguistic-but-not-physical separation.

Battle Axe spoke “Para-Balto-Finnic”?

The Balto-Finnic-speaking nature of Battle Axe is thus supported by:

  • The lack of non-Uralic substrates in Balto-Finnic territory (Kallio 2015).
  • The early separation of Samic and Finnic from Mordvinic, and the virtual identity of Proto-West-Uralic and Proto-Uralic, which suggests that Proto-Uralic spread fast (Parpola 2012).
  • The scarce non-Uralic topo-hydronymy in the East Baltic and around the Gulf of Finland (Saarikivi 2004), comparable to that on the Upper Volga region.
  • The strong influence of a Balto-Finnic-like substrate on Pre-Germanic (or, in Kallio’s opinion, the same Scandinavian substrate influencing both Germanic and Balto-Finnic at the same time), and the continued influence of Balto-Finnic on Proto-Baltic and Proto-Slavic.
  • The continued influence of Corded Ware-derived groups in central-east Sweden in Finland and the East Baltic in terms of agricultural innovations appearing in the LBA, compatible with Schrijver’s proposal of intermediate Germanic-shifted Balto-Finnic groups and Balto-Finnic groups influenced by their pronunciation.
  • The intense Palaeo-Germanic and late Balto-Slavic / early Proto-Baltic superstrate on Balto-Finnic, which place all three dialects around the Baltic Sea since the Early Bronze Age.
  • The easy replacement of a hypothetic Para-Balto-Finnic dialect by incoming Proto-Balto-Finnic-speaking peoples (say, with textile ceramics), without much linguistic impact.

In fact, the continuous contacts of the East Baltic with the Volga, and especially the close interaction with Akozino warrior-traders just before the Tarand-grave period, could be the actual origin of the recent (if any) Finnic-Mordvinic connections that need to be traced back to the LBA-IA (maybe here the number ‘ten’), since most of them can be related to a Pit-Comb Ware culture substrate and earlier contacts through the forest zone, which Samic (due to its early split and presence to the north of the Gulf of Finland during the BA) does not share. In fact, some of them can be traced back to Balto-Finnic first

These are the most often mentioned, in order of descending relevance for a shared ancient community:

  • Noun paradigms and the form and function of individual cases.
  • The geminate *mm (foreign to Proto-Uralic before the development of Fennic under Germanic influence) and other non-Uralic consonant clusters.
  • The change of numeral *luka ‘ten’ with (non-Uralic) *kümmen.
  • The presence of loanwords of non-Uralic origin, related to farming and trees, potentially Palaeo-European in nature.

It’s not only a question of quantity. Are these shared Mordvinic – Balto-Finnic traits really more relevant than, say, those between Italo-Celtic, which are supposed to have formed a community for a very short period at the end of the 3rd millennium around the Alps? Are these traits even sufficient to propose a common early Mordvinic-Finnic group within West Uralic, rather than loose Mordvinic – Balto-Finnic contacts, i.e. contacts between East Baltic (Textile Ceramics) and Volga-Kama (Netted Ware)?

Based on the alternative (Kallio’s) view of continued contacts between Textile Ceramics groups, even without knowing anything about linguistics, you can guess that Parpola is spinning very thin when assuming that these changes suggest that Balto-Finnic may have expanded with Akozino warrior-traders, separating thus ca. 800 BC from Mordvinic…

Genetic findings now clearly help dismiss any meaningful population impact in the LBA-IA transition, although any linguist can obviously argue for linguistic change in spite of major genetic continuity. But then we are stuck in the pre-ancient DNA era, so what’s ancient DNA for.

Genetic continuity = language continuity?

In the end, it’s very difficult to say how much language continuity there is around Estonia since the arrival of Corded Ware peoples. Looking at Modern Estonians, they have been clearly influenced by recent contacts with Baltic- and Germanic-speaking peoples clustering to the south-west in the PCA. They seem to have also received contacts from north(-east)ern peoples, likely from Finland, evidenced by their shifts toward the modern Estonian cluster during and after the Middle Ages, with a slight increase in Siberian ancestry and N1c subclades associated with Lovozero Ware. How much language change did these contacts bring? Maybe an expansion of Gulf of Finland Finnic (Northern Estonian) over Inland Finnic (Southern Estonian) and Gulf of Riga Finnic (Livonian)? Difficult to know, exactly, but, in the traditional view of Balto-Finnic dialectal distribution among Uralicists like Kallio, possibly no change at all.

So, if the obvious changes in the Estonia_MA cluster relative to Estonia_IA cluster and Estonia_Modern relative to Estonia_MA do not represent radical language change…Why would Estonia_IA represent a change relative to Estonia_BA, when it is statistically basically the same? Or Estonia_BA relative to CWC_Baltic? Because of the infiltration of haplogroup N1c around the whole Baltic? Because of the occasional 1% “Siberian” ancestry in some non-locals of varied haplogroups across the whole Baltic area?

In spite of all this, the amount of special pleading we are seeing among openly Nordicist amateurs when discussing the Uralic homeland relative to the Indo-European question in genetics has become a matter of plain willful ignorance. Like the living corpses of the Anatolian homeland, the Armenian homeland, the OIT proponents, or the nativist Basque R1b association, the personal involvement in the revival of “R1a=Indo-European” and “N=Uralic” trends is just painful to watch.

[Next post in this line, if I manage to make time for it: “Genetic (dis)continuity in Central Europe“. Let’s see if early Balts and early Slavs, as well as Germanic peoples, show a cluster closer to Danubian EBA (viz. Maros), Hungary-Balkans BA, and Urnfield-related samples than their predecessors in their areas, i.e. away from East Corded Ware groups… If you want, you can enjoy for the moment the new PCAs I could get done and the tentative map of languages in the Early Bronze Age, that will probably give you the right idea about early Indo-European and Uralic population movements]

R1a-Z280 and R1a-Z93 shared by ancient Finno-Ugric populations; N1c-Tat expanded with Micro-Altaic

Two important papers have appeared regarding the supposed link of Uralians with haplogroup N.

Avars of haplogroup N1c-Tat

Preprint Genetic insights into the social organisation of the Avar period elite in the 7th century AD Carpathian Basin, by Csáky et al. bioRxiv (2019).

Interesting excerpts (emphasis mine):

After 568 AD the Avars settled in the Carpathian Basin and founded the Avar Qaganate that was an important power in Central Europe until the 9th century. Part of the Avar society was probably of Asian origin, however the localisation of their homeland is hampered by the scarcity of historical and archaeological data.

Here, we study mitogenome and Y chromosomal STR variability of twenty-six individuals, a number of them representing a well-characterised elite group buried at the centre of the Carpathian Basin more than a century after the Avar conquest.

The Y-STR analyses of 17 males give evidence on a surprisingly homogeneous Y chromosomal composition. Y chromosomal STR profiles of 14 males could be assigned to haplogroup N-Tat (also N1a1-M46). N-Tat haplotype I was found in four males from Kunpeszér with identical alleles on at least nine loci. The full Y-STR haplotype I, reconstructed from AC17 with 17 detected STRs, is rare in our days. Only nine matches were found among haplotypes in YHRD database, such as samples from the Ural Region, Northern Europe (Estonia, Finland), and Western Alaska (Yupiks). We performed Median Joining (MJ) network analysis using N-Tat haplotypes with ten shared STR loci (Fig. 3, Table S9). All modern N-Tat samples included in the network had derived allele of L708 as well. Haplotype I (Cluster 1 in Fig. 3) is shared by eight populations on the MJ network among the 24 identical haplotypes. Cluster 1 represents the founding lineage, as it is described in Siberian populations, because this haplotype is shared by the most populations and it is more diverse than Cluster 2.

Nine males share N-Tat haplotype II (on a minimum of eight detected alleles), all of them buried in the Danube-Tisza Interfluve. We found 30 direct matches of this N-Tat haplotype II in the YHRD database, using the complete 17 STR Y-filer profile of AC1, AC12, AC14, AC15, AC19 samples. Most hits came from Mongolia (seven Buryats and one Khalkh) and from Russia (six Yakuts), but identical haplotypes also occur in China (five in Xinjiang and four in Inner Mongolia provinces). On the MJ network, this haplotype II is represented by Cluster 2 and is composed of 45 samples (including 32 Buryats) from six populations (Fig. 3).

y-str-haplogroup-n-mongolian-ugrians
Median Joining network of 162 N-Tat Y-STR haplotypes Allelic information of ten Y-STR loci were used for the network. Only those Avar samples were included, which had results for these ten Y-STR loci. The founder haplotype I (Cluster 1) is shared by eight populations including three Mongolian, three Székely, three northern Mansi, two southern Mansi, two Hungarian, eight Khanty, one Finn and two Avar (AC17, AC26) chromosomes. Haplotype II (Cluster 2) includes 45 haplotypes from six populations studied: 32 Buryats, two Mongolians, one Székely, one Uzbek, one Uzbek Madjar, two northern Mansi and six Avars (AC1, AC12, AC14, AC15, AC19 and KSZ 37). Haplotype III (indicated by a red arrow) is AC8. Information on the modern reference samples is seen in Table S9.

A third N-Tat lineage (type III) was represented only once in the Avar dataset (AC8), and has no direct modern parallels from the YHRD database. This haplotype on the MJ network (see red arrow in Fig. 3) seems to be a descendent from other haplotype cluster that is shared by three populations (two Buryat from Mongolia, three Khanty and one Northern Mansi samples). This haplotype cluster also differs one molecular step (locus DYS393) from haplotype II. We classified the Avar samples to downstream subgroup N-F4205 within the N-Tat haplogroup, based on the results of ours and Ilumäe et al.18 and constructed a second network (Fig. S4). The N-F4205 network results support the assumption that the N-Tat Avar samples belong to N-F4205 subgroup (see SI chapter 1d for more details).

Based on our calculation, the age of accumulated STR variance (TMRCA) within N-Tat lineage for all samples is 7.0 kya (95% CI: 4.9 – 9.2 kya), considering the core haplotype (Cluster 1) to be the founding lineage. Y haplogroup N-Tat was not detected by large scale Eurasian ancient DNA studies but it occurs in late Bronze Age Inner Mongolia and late medieval Yakuts, among them N-Tat has still the highest frequency.

Two males (AC4 and AC7) from the Transtisza group belong to two different haplotypes of Y-haplogroup Q1. Both Q1a-F1096 and Q1b-M346 haplotypes have neither direct nor one step neighbour matches in the worldwide YHRD database. A network of the Q1b-M346 haplotype shows that this male had a probable Altaian or South Siberian paternal genetic origin.

EDIT (5 APR 2019): The paper offers an interesting late sample before the arrival of Hungarian conquerors, although we don’t know which precise lineage the sample belongs to:

One sample in our dataset (HC9) comes from this population, and both his mtDNA (T1a1b) and Y chromosome (R1a) support Eastern European connections. (…) Furthermore, we excluded sample HC9 from population-genetic statistical analyses because it belongs to a later period (end of 7th – early 9th centuries)

Apparently, then, results are consistent with what was already known from studies of modern populations:

According to Ilumäe et al. study, the frequency peak of N-F4205 (N3a5-F4205) chromosomes is close to the Transbaikal region of Southern Siberia and Mongolia, and we conclude that most Avar N-Tat chromosomes probably originated from a common source population of people living in this area, completely in line with the results of Ilumäe et al.

Finno-Ugrians share haplogroup R1a-Z280

Another paper, behind paywall, Genetic history of Bashkirian Mari and Southern Mansi ethnic groups in the Ural region, by Dudás et al. Molecular Genetics and Genomics (2019).

Interesting excerpts (emphasis mine):

Y‑chromosome diversity

The most frequent haplogroups of the Bashkirian Maris were N1b-P43 (42%), R1a-Z280 (16%), R1a-Z93 (16%), N1c-Tat (13%), and J2-M172 (7%). Furthermore, subgroup R1b-M343 accounted for 4% and I2a-P37 covered 2% of the lineages. None of the Mari N1c Y chromosomes belonged to the N1c subgroups investigated (L1034, VL29, Z1936).

In the case of the Southern Mansi males, the most frequent haplogroups were N1b-P43 (33%), N1c-L1034 (28%) and R1a-Z280 (19%). The frequencies of the remaining haplogroups were as follows: R1a-M458 (6%), I1-L22 (3%), I2a-P37 (3%), and R1b-P312 (3%). The haplotype and haplogroup diversities of the Bashkirian Mari group were 0.9929 and 0.7657, whereas these values for the Southern Mansi were 0.9984 and 0.7873, respectively. The results show that, in both populations, haplotypes are much more diverse than haplogroups.

Genetic structure

(..) the studied Bashkirian Mari and Southern Mansi population groups formed a compact cluster along with two Khanty, Northern Mansi, Mari, and Estonian populations based on close Fst-genetic distances (< 0.05), with nonsignificant p values (p > 0.05) except for the Estonian population. All of these populations belong to the Finno-Ugric language family. Interestingly, the other Mansi population studied by Pimenoff et al. (2008) (pop # 38) was located a great distance from the Southern Mansi group (0.268). In addition, the Bashkir population (pop # 6) did not show a close genetic affinity to the Bashkirian Mari group (0.194), even though it is the host population. However, the Russian population from the Eastern European region of Russia (pop # 49) showed a genetic distance of 0.055 with the Southern Mansi group. All Hungarian speaking populations (pops 13, 22, 23, 24, 50, and 51) showed close genetic affinities to each other and to the neighbouring populations, but not to the two studied populations.

Phylogenetic analysis

Median-joining networks were constructed for:

N-P43 (earlier N1b):

(…) TMRCA estimates for this haplogroup were made for all P43 samples (n = 157) 8.7 kya (95% CI 6.7–10.8 kya), for the N-P43 Asian.

N1c-Tat:

(…) 75% of Buryats belonged to Haplotype 2, indicating that the Buryats studied by us is a young and isolated population (Bíró et al. 2015). Bashkirian Mari samples derive from Haplotype 2 via Haplotype 3 (see dark purple circles on the top of Fig. 6a). Haplotype 3 contained six males (2 Buryat, 1 Northern Mansi, and 3 Khanty samples from Pimenoff et al. 2008). The biggest Bashkirian Mari haplotype node (3 Mari samples) was positioned three mutational steps away from Haplotype 1 and the remaining Mari samples can be derived from this haplotype. Southern Mansi haplotypes were scattered within the network except for two, which formed a smaller haplotype node with two Northern Mansi and two Khanty samples from Pimenoff et al. (2008).

(2008)

R1a-Z280 haplotypes, shared by Maris, Mansis, and Hungarians, hence ancient Finno-Ugrians:

The founder R1a-Z280 haplotype was shared by four samples from four populations (1 Bashkirian Mari; 1 Southern Mansi; 1 Hungarian speaking Székely; and 1 Hungarian), as presented in Fig. 7 (Haplotype 1). Haplotype 2 included five males (3 Bashkirian Mari and 2 Hungarian), as it can be seen in Fig. 7. Haplotype 4 included two shared haplotypes (1 Bashkirian Mari and one Hungarian speaking Csángó). The remaining two Bashkirian Mari haplotypes differ from the founder haplotype (Haplotype 1) by two mutational steps via Hungarian or Hungarian and Bashkirian Mari shared haplotypes. Beside Haplotype 1, the remaining Southern Mansi haplotypes were shared with Hungarians (Haplotype 5 or turquoise blue and red-coloured circles above Haplotype 7) or with Hungarians and Hungarian speaking Székely group (Haplotypes 3, 5, and 6). Haplotype 7 included ten Hungarian speakers (Hungarian, Székely, and Csángó). One Hungarian and one Uzbek Khwarezm shared haplotype can be found in Fig. 7 as well (red and white-coloured circle). All the other haplotypes were scattered in the network. The age of accumulated STR variation within R1a-Z280 lineage for 93 samples is estimated to be 9.4 kya (95% CI 6.5–12.4 kya) considering Haplotype 1 (Fig. 7) to be the founder.

R1a-Z93 as isolated lineages among Permic and Ugric populations:

Figure 8 depicts an MJ network of R1a-Z93* samples using 106 haplotypes from the 14 populations (Fig. 8). All of the Bashkirian Mari samples (7 haplotypes) formed a very isolated branch and differed from the one Hungarian haplotype (Fig. 8, see Haplotype 1) by seven mutational steps as well from two Uzbek Tashkent samples (see Haplotype 3). Another Hungarian sample shared two haplotypes of Uzbek Khwarezm samples in Haplotype 4. This haplotype can be derived from Haplotype 3 (Uzbek Tashkent). Haplotype 2 included one Hungarian and one Khakassian male. The remaining three Hungarian haplotypes are outliers in the network and are not shared by any sample. The other population samples included in the network either form independent clusters such as Altaians, Khakassians, Khanties, and Uzbek Madjars or were scattered in the network. The age of accumulated STR variation (TMRCA) within R1a-Z93* lineage for 106 samples is estimated as 11.6 kya (95% CI 9.3–14.0 kya) considering an Armenian haplotype (Fig. 8, “A”) to be the founder and the median haplotype.

Comments

The results of modern populations for N (especially N1c) subclades show really wide clusters and ancient TMRCA, consistent with their known ancient and wide distribution in northern and eastern Eurasian groups, and thus with infiltration of different lineages with eastern nomads (and northern Arctic populations) coupled with later bottlenecks, as well as acculturation of groups.

EDIT (2 APR): Interesting is the specific subclade to which ancient Mongolic-speaking Avars belong (information from Yfull) N1c-F4205 (TMRCA ca. 500 BC), subclade of N1c-Y6058 (formed ca. 2800 BC, TMRCA ca. 2800 BC). This branch also gives the “European” branch N1c-CTS10760 (formed ca. 2800 BC, TMRCA ca. 2100 BC), and is subclade of a branch of N1c-L392 (formed ca. 4400 BC, TMRCA ca. 2800 BC). A northern expansion of N1c-L392 is probably represented by its branch N1c-Z1936 (formed ca. 2800, TMRCA ca. 2100 BC), the most likely candidate to appear in the Kola Peninsula in the Bronze Age as the Palaeo-Laplandic population (see here). Read more about potential routes of expansion of haplogroup N.

On the other hand, R1a-Z280 lineages form a tight cluster connecting Permic with Ugric groups, with R1a-Z93 showing early isolation (probably) between Cis-Urals and Trans-Urals regions. While both Corded Ware lineages in Finno-Ugrians are most likely related to the Abashevo expansion through Seima-Turbino and the Andronovo-like Horizon (and potentially later Eurasian expansions), a plausible hypothesis would be that Finno-Ugrians are related to an expansion of R1a-Z283 haplogroups (we already knew about the Finno-Permic connection), while the ancient connection between Permians and Hungarians with R1a-Z93 would correspond to this haplogroup’s potentially tighter link with an early Samoyedic split.

I don’t think that an explosive expansion of eastern Corded Ware groups of R1a-Z645 lineages will show a clear-cut division of haplogroups among Eastern Uralic groups, though, and culturally I doubt we will have such a clear image, either (similar to how the explosive expansion of Bell Beakers cannot be easily divided by regional/language group into R1b-L151 subclades before the known bottlenecks). Relevant in this regard are the known Z93 samples from the Árpád dynasty.

Nevertheless, this data may represent a slightly more recent wave of R1a-Z280 lineages linked to the expansion of Ugric into the Trans-Uralian region, after their split from Finno-Permic, still in close contact with Indo-Iranians in Poltavka and Sintashta-Potapovka, evident from the early and late Indo-Iranian borrowings, during a common period when Samoyedic had already separated.

Such a “Z283 over Z93” layer in the Trans-Urals (and Cis-Urals?) forest-steppes would be similar to the apparent replacement of Z284 by Z282 in the Eastern Baltic during the Bronze Age (possibly with the second or Estonian Battle Axe wave or, much more likely during later population movements). Such an early R1a-Z93 split could potentially be supported also by the separation into bottlenecks under “Northern” (R1a-Z283) Finno-Ugric-speaking Abashevo-related groups and “Southern” (R1a-Z93) acculturated Indo-Iranian-speaking Abashevo migrants developing Sintashta-Potapovka admixing with Poltavka R1b-Z2103 herders.

Conclusion

Let’s review some of the most common myths about Hungarians (and Finno-Ugrians in general) repeated ad nauseam, side by side with my assertions:

❌ N (especially N1c-Tat) in ancient and modern samples represent the True Uralic™ N1c peoples including Magyar tribes? Nope.

✅ Ancient N (especially N1c-Tat) lineages among Uralic populations expanded relatively recently, and differently in different regions (including eastern steppe nomads and northern arctic populations) not associated with a particular language or language group? Yep (read the series on Corded Ware = Uralic expansion).

❌ Modern Hungarian R1a-Z280 lineages represent the majority of the native population, poor Slavic ‘peasants’ from the Carpathian Basin, forcibly acculturated by a minority of bad bad Hungarian hordes? Nope.

✅ Modern Hungarian R1a-Z280 subclades represent Ugric lineages in common with ancient R1a-Z645 Finno-Ugric populations from north-eastern Europe and the Trans-Urals? Yep (see Avars and Ugrians).

❌ Modern Hungarian R1a-Z93 lineages represent acculturated Iranian/Turkic peoples from the steppes? Not likely.

✅ Modern Hungarian R1a-Z93 lineages represent a remnant of the expansion of Corded Ware to the east, potentially more clearly associated with Samoyedic? Much more likely.

Sooo, the theory of a “diluted” Y-DNA in Modern Hungarians from originally fully N-dominated conquerors subjugating native R1a-Z280 Slavs from the Carpathian Basin is not backed up by genetic studies? The ethnic Iranian-Turkic R1a-Z93 federation in the steppes that ended up speaking Magyar is not real?? Who would’ve thunk.

Another true story whose rejection in genetics could not be predicted, like, not at all.

Totally unexpected, too, the drift of “R1a=IE” fans with the newest genetic findings towards a Molgen-like “Yamna/R1b = Vasconic-Caucasian”, “N1c = Uralic-Altaic”, and “R1a = the origin of the white world in Mother Russia”. So much for the supposed interest in “Steppe ancestry” and fancy statistics.

Aquitanians and Iberians of haplogroup R1b are exactly like Indo-Iranians and Balto-Slavs of haplogroup R1a

The final paper on Indo-Iranian peoples, by Narasimhan and Patterson (see preprint), is soon to be published, according to the first author’s Twitter account.

One of the interesting details of the development of Bronze Age Iberian ethnolinguistic landscape was the making of Proto-Iberian and Proto-Basque communities, which we already knew were going to show R1b-P312 lineages, a haplogroup clearly associated during the Bell Beaker period with expanding North-West Indo-Europeans:

From the Bronze Age (~2200–900 BCE), we increase the available dataset from 7 to 60 individuals and show how ancestry from the Pontic-Caspian steppe (Steppe ancestry) appeared throughout Iberia in this period, albeit with less impact in the south. The earliest evidence is in 14 individuals dated to ~2500–2000 BCE who coexisted with local people without Steppe ancestry. These groups lived in close proximity and admixed to form the Bronze Age population after 2000 BCE with ~40% ancestry from incoming groups. Y-chromosome turnover was even more pronounced, as the lineages common in Copper Age Iberia (I2, G2, and H) were almost completely replaced by one lineage, R1b-M269.

The arrival of East Bell Beakers speaking Indo-European languages involved, nevertheless, the survival of the two non-IE communities isolated from each other – likely stemming from south-western France and south-eastern Iberia – thanks to a long-lasting process of migration and admixture. There are some common misconceptions about ancient languages in Iberia which may have caused some wrong interpretations of the data in the paper and elsewhere:

NOTE. A simple reading of Iberian prehistory would be enough to correct these. Two recent books on this subject are Villar’s Indoeuropeos, iberos, vascos y otros parientes and Vascos, celtas e indoeuropeos. Genes y lenguas.

Iberian languages were spoken at least in the Mediterranean and the south (ca. “1/3 of Iberia“) during the Bronze Age.

Nope, we only know the approximate location of Iberian culture and inscriptions from the Late Iron Age, and they occupy the south-eastern and eastern coastal areas, but before that it is unclear where they were spoken. In fact, it seems evident now that the arrival of Urnfield groups from the north marks the arrival of Celtic-speaking peoples, as we can infer from the increase in Central European admixture, while the expansion of anthropomorphic stelae from the north-west must have marked the expansion of Lusitanian.

Vasconic was spoken in both sides of the Pyrenees, as it was in the Middle Ages.

Wrong. One of the worst mistakes I am seeing in many comments since the paper was published, although admittedly the paper goes around this problem talking about “Modern Basques”. Vasconic toponyms appear south of the Pyrenees only after the Roman conquests, and tribes of the south-western Pyrenees and Cantabrian regions were likely Celtic-speaking peoples. Aquitanians (north of the western Pyrenees) are the only known ancient Vasconic-speaking population in proto-historic times, ergo the arrival of Bell Beakers in Iberia was most likely accompanied by Indo-European languages which were later replaced by Celtic expanding from Central Europe, and Iberian expanding from south-east Iberia, and only later with Latin and Vasconic.

Ligurian is non-Indo-European, and Lusitanian is Celtic-like, so Iberia must have been mostly non-Indo-European-speaking.

The fragmentary material available on Ligurian is enough to show that phonetically it is a NWIE dialect of non-Celtic, non-Italic nature, much like Lusitanian; that is, unless you follow laryngeals up to Celtic or Italic, in which case you can argue anything about this or any other IE language, as people who reconstruct laryngeals for Baltic in the common era do.

EDIT (19 Mar 2019): It was not clear enough from this paragraph, because Ligurian-like languages in NE Iberia is just a hypothesis based on the archaeological connection of the whole southern France Bell Beaker region. My aim was to repeat the idea that Old European hydro-toponymy is older in NE Iberia (as almost anywhere in Iberia) than Iberian toponymy, so the initial hypothesis is that:

  1. a Palaeo-European language (as Villar puts it) expanded into most regions of Iberia in ancient times (he considered at some point the Mesolithic, but that is obviously wrong, as we know now); then
  2. Celts expanded at least to the Ebro River Basin; then
  3. Iberians expanded to the north and replaced these in NE Iberia; and only then
  4. after the Roman invasion, around the start of the Common Era, appear Vasconic toponyms south of the Pyrenees.

Lusitanian obviously does not qualify as Celtic, lacking the most essential traits that define Celticness…Unless you define “(Para-)Celtic” as Pre-Proto-Celtic-like, or anything of the sort to support some Atlantic continuity, in which case you can also argue that Pre-Italic or Pre-Germanic are Celtic, because you would be essentially describing North-West Indo-European

If Basques have R1b, it’s because of a culture of “matrilocality” as opposed to the “patrilocality” of Indo-Europeans

So wrong it hurts my eyes every time I read this. Not only does matrilocality in a regional group have few known effects in genetics, but there are many well-documented cases of population replacement (with either ancestry or Y-DNA haplogroups, or both) without language replacement, without a need to resort to “matrilineality” or “matrilocality” or any other cultural difference in any of these cases.

In fact, it seems quite likely now that isolated ancient peoples north of the Pyrenees will show a gradual replacement of surviving I2a lineages by neighbouring R1b, while early Iberian R1b-DF27 lineages are associated with Lusitanians, and later incoming R1b-DF27 lineages (apart from other haplogroups) are most likely associated with incoming Celts, which must have remained in north-central and central-east European groups.

NOTE. Notice how R1a is fully absent from all known early Indo-European peoples to date, whether Iberian IE, British IE, Italic, or Greek. The absence of R1a in Iberia after the arrival of Celts is even more telling of the origin of expanding Celts in Central Europe.

I haven’t had enough time to add Iberian samples to my spreadsheet, and hence neither to the ASoSaH texts nor maps/PCAs (and I don’t plan to, because it’s more efficient for me to add both, Asian and Iberian samples, at the same time), but luckily Maciamo has summed it up on Eupedia. Or, graphically depicted in the paper for the southeast:

iberia-haplogroups
Y chromosome haplogroup composition of individuals from southeast Iberia during the past 2000 years. The general Iberian Bronze and Iron Age population is included for comparison. Modified from Olalde et al. (2019).

Does this continued influx of Y-DNA haplogroups in Iberia with different cultures represent permanent changes in language? Are, therefore, modern Iberian languages derived from Lusitanian, Sorothaptic/Celtic, Greek, Phoenician, East or West Germanic, Hebrew, Berber, or Arabic languages? Obviously not. Same with Italy (see the recent preprint on modern Italians by Raveane et al. 2018), with France, with Germany, or with Greece.

If that happens in European regions with a known ancient history, why would the recent expansions and bottlenecks of R1b in modern Basques (or N1c around the Baltic, or R1a in Slavs) in the Middle Ages represent an ancestral language surviving into modern times?

Indo-Iranians

If something is clear from Narasimhan, Patterson, et al. (2018), is that we know finally the timing of the introduction and expansion of R1a-Z645 lineages among Indo-Iranians.

We could already propose since 2015 that a slow admixture happened in the steppes, based on archaeological finds, due to settlement elites dominating over common peoples, coupled with the known Uralic linguistic traits of Indo-Iranian (and known Indo-Iranian influence on Finno-Ugric) – as I did in the first version of the Indo-European demic diffusion model.

The new huge sampling of Sintashta – combined with that of Catacomb, Poltavka, Potapovka, Andronovo, and Srubna – shows quite clearly how this long-term admixture process between Uralic peoples and Indo-Iranians happened between forest-steppe CWC (mainly Abashevo) and steppe groups. The situation is not different from that of Iberia ca. 2500-2000 BC; from Narasimhan, Patterson, et al. (2018):

We combined the newly reported data from Kamennyi Ambar 5 with previously reported data from the Sintashta 5 individuals (10). We observed a main cluster of Sintashta individuals that was similar to Srubnaya, Potapovka, and Andronovo in being well modeled as a mixture of Yamnaya-related and Anatolian Neolithic (European agriculturalist-related) ancestry.

Even with such few words referring to one of the most important data in the paper about what happened in the steppes, Wang et al. (2018) help us understand what really happened with this simplistic concept of “steppe ancestry” regarding Yamna vs. Corded Ware differences:

anatolia-neolithic-steppe-eneolithic
Image modified from Wang et al. (2018). Marked are: in red, approximate limit of Anatolia_Neolithic ancestry found in Yamna populations; in blue, Corded Ware-related groups. “Modelling results for the Steppe and Caucasus 1128 cluster. Admixture proportions based on (temporally and geographically) distal and proximal models, showing additional Anatolian farmer-related ancestry in Steppe groups as well as additional gene flow from the south in some of the Steppe groups as well as the Caucasus groups (see also Supplementary Tables 10, 14 and 20).”

As with Iberia (or any prehistoric region), the details of how exactly this language change happened are not evident, but we only need a plausible explanation coupled with archaeology and linguistics. Poltavka, Potapovka, and Sintashta samples – like the few available Iberian ones ca. 2500-2000 BC – offer a good picture of the cohabitation of R1b-L23 (mainly Z2103) and R1a-Z645 (mainly Z93+): a glimpse at the likely presence of R1a-Z93 within settlements – which must have evolved as the dominant elites – in a society where the majority of the population was initially formed by nomad herders (probably most R1b-Z2103), who were usually buried outside of the main settlements.

Will the upcoming Narasimhan, Patterson et al. (2019) deal with this problem of how R1a-M417 replaced R1b-M269, and how the so-called “Steppe_MLBA” (i.e. Corded Ware) ancestry admixed with “Steppe_EMBA” (i.e. Yamnaya) ancestry in the steppes, and which one of their languages survived in the region (that is, the same the Reich Lab has done with Iberia)? Not likely. The ‘genetic wars’ in Iberia deal with haplogroup R1b-P312, and how it was neither ‘native’ nor associated with Basques and non-Indo-European peoples in general. The ‘genetic wars’ in South Asia are concerned with the steppe origin of R1a, to prove that it is not a ‘native’ haplogroup to India, and thus neither are Indo-Aryan languages. To each region a politically correct account of genetic finds, with enough care not to fully dismiss national myths, it seems.

NOTE. Funnily enough, these ‘genetic wars’ are the making of geneticists since the 1990s and 2000s, so we are still in the midst of mostly internal wars caused by what they write. Just as genetic papers of the 2020s will most likely be a reaction to what they are writing right now about “steppe ancestry” and R1a. You won’t find much change to the linguistic reconstruction in this whole period, except for the most multicolored glottochronological proposals…

The first author of the paper has engaged, as far as I could see in Twitter, in dialogue with Hindu nationalists who try to dismiss the arrival of steppe ancestry and R1a into South Asia as inconclusive (to support the potential origin of Sanskrit millennia ago in the Indus Valley Civilization). How can geneticists deal with the real problem here (the original ethnolinguistic group expanding with Corded Ware), when they have to fend off anti-steppists from Europe and Asia? How can they do it, when they themselves are part of the same societies that demand a politically correct presentation of data?

This is how the data on the most likely Indo-Iranian-speaking region should be presented in an ideal world, where – as in the Iberia paper – geneticists would look closely to the Volga-Ural region to discover what happened with Proto-Indo-Iranians from their earliest to their latest stage, instead of constantly looking for sites close to the Indus Valley to demonstrate who knows what about modern Indian culture:

Colors indicate the Y-chromosome haplogroup for each male. Red lines represent period of admixture. Modified from Olalde et al. (2019).

Now try and tell Hindu nationalists that Sanskrit expanded from an Early Bronze Age steppe community of R1b-rich nomadic herders that spoke Pre-Indo-Iranian, which was dominated and eventually (genetically) mostly replaced by elite Uralic-speaking R1a peoples from the Russian forest, hence the known phonetic (and some morphological) traits that remained. Good luck with the Europhobic shitstorm ahead..

Balto-Slavic

Iberian cultures, already with a majority of R1b lineages, show a clear northward expansion over previously Urnfield-like groups of north-east Iberia and Mediterranean France (which we now know probably represent the migration of Celts from central Europe). Similarly, Eastern Balts already under a majority of R1a lineages expanded likely into the Baltic region at the same time as the outlier from Turlojiškė (ca. 1075 BC), which represents the first obvious contacts of central-east Europe with the Baltic.

Iberia shows a more recent influx of central and eastern Mediterranean peoples, one of which eventually succeeded in imposing their language in Western Europe: Romans were possibly associated mainly with R1b-U152, apart from many other lineages. Proto-Slavs probably expanded later than Celts, too, connected to the disintegration of the Lusatian culture, and they were at some point associated with R1a-M458 and R1a-Z280(xZ92) lineages, apart from others already found in Early Slavs.

This parallel between Iberia and eastern Europe is no coincidence: as Europe entered the Bronze Age, chiefdom-based systems became common, and thus the connection of ancestry or haplogroups with ethnolinguistic groups became weaker.

What happened earlier (and who may represent the Pre-Balto-Slavic community) will be clearer when we have enough eastern European samples, but basically we will be able to depict this admixture of NWIE-speaking BBC-derived peoples with Uralic-speaking CWC-derived groups (since Uralic is known to have strongly influenced Balto-Slavic), similar to the admixture found in Indo-Iranians, more or less like this:

Colors indicate the Y-chromosome haplogroup for each male. Red lines represent period of admixture. Modified from Olalde et al. (2019).

The Early Scythian period marked a still stronger chiefdom-based system which promoted the creation of alliances and federation-like groups, with an earlier representation of the system expanding from north-eastern Europe around the Baltic Sea, precisely during the spread of Akozino warrior-traders (in turn related to the Scythian influence in the forest-steppes), who are the most likely ancestors of most N1c-V29 lineages among modern Germanic, Balto-Slavic, and Volga-Finnic peoples.

Modern haplogroup+language = ancient ones?

It is not difficult to realize, then, that the complex modern genetic picture in Eastern Europe and around the Urals, and also in South Asia (like that of the Aegean or Anatolia) is similar to the Iron Age / medieval Iberian one, and that following modern R1a as an Indo-European marker just because some modern Indo-European-speaking groups showed it was always a flawed methodology; as flawed as following R1b for ancient Vasconic groups, or N1c for ancient Uralic groups.

Why people would argue that haplogroups mean continuity (e.g. R1b with Basques, N1c with Finns, R1a with Slavs, etc.) may be understood, if one lives still in the 2000s. Just like why one would argue that Corded Ware is Indo-European, because of Gimbutas’ huge influence since the 1960s with her myth of “Kurgan peoples”. Not many denied these haplogroup associations, because there was no reason to do it, and those who did usually aligned with a defense of descriptive archaeology.

However, it is a growing paradox that some people interested in genetics today would now, after the Iberian paper, need to:

  • accept that ancient Iberians and probably Aquitanians (each from different regions, and probably from different “Basque-Iberian dialects” in the Chalcolithic, if both were actually related) show eventually expansions with R1b-L23, the haplogroup most obviously associated with expanding Indo-Europeans;
  • acknowledge that modern Iberians have many different lineages derived from prehistoric or historic peoples (Celts, Phoenicians, Greeks, Romans, Jews, Goths, Berbers, Arabs), which have undergone different bottlenecks, the last ones during the Reconquista, but none of their languages have survived;
  • realize that a similar picture is to be found everywhere in central and western Europe since the first proto-historic records, with language replacement in spite of genetic continuity, such as the British Isles (and R1b-L21 continuity) after the arrival of Celts, Romans, Anglo-Saxons, Vikings, or Normans;
  • but, at the same time, continue blindly asserting that haplogroup R1a + “steppe ancestry” represent some kind of supernatural combination which must show continuity with their modern Indo-Iranian or Balto-Slavic language from time immemorial.

Behave, pretty please

The ‘conservative’ message espoused by some geneticists and amateur genealogists here is basically as follows:

  • Let’s not rush to new theories that contradict the 2000s, lest some people get offended by granddaddy not being these pure whatever wherever as they believed, and let’s wait some 5, 10, or 20 years, as long as necessary – to see if some corner of the Yamna culture shows R1a, or some region in north-eastern Europe shows N1c, or some Atlantic Chalcolithic sample shows R1b – to challenge our preferred theories, if we actually need to challenge anything at all, because it hurts too much.
  • Just don’t let many of these genetic genealogists or academics of our time be unhappy, pretty please with sugar on top, and let them slowly adapt to reality with more and more pet theories to fit everything together (past theories + present data), so maybe when all of them are gone, within 50 or 70 years, society can smoothly begin to move on and propose something closer to reality, but always as politically correct as possible for the next generations.
  • For starters, let’s discuss now (yet again) that Bell Beakers may not have been Indo-European at all, despite showing (unlike Corded Ware) clearly Yamna male lineages and ancestry, because then Corded Ware and R1a could not have been Indo-European and that’s terrible, so maybe Bell Beakers are too brachycephalic to speak Indo-European or something, or they were stopped by the Fearsome Tisza River, or they are not pure Dutch Single Grave in The South hence not Indo-European, or whatever, and that’s why Iron Age Iberians or Etruscans show non-Indo-European languages. That’s not disrespectful to the history of certain peoples, of course not, but talking about the evident R1a-Uralic connection is, because this is The South, not The North, and respect works differently there.
  • Just don’t talk about how Slavs and Balts enter history more than 1,500 years later than Indo-European peoples in Western and Southern Europe, including Iberia, and assume a heroic continuity of Balts and Slavs as pure R1a ‘steppe-like’ peoples dominating over thousands of kms. in the Baltic, Fennoscandia, eastern Europe, and northern Asia for 5,000 years, with multiple Balto-Slavs-over-Balto-Slavs migrations, because these absolute units of Indo-European peoples were a trip and a half. They are the Asterix and Obelix of white Indo-European prehistory.
  • Perhaps in the meantime we can also invent some new glottochronological dialectal scheme that fits the expansion of Sredni Stog/Corded Ware with (Germano-?)Indo-Slavonic separated earlier than any other Late PIE dialect; and Finno-Volgaic later than any other Uralic dialect, in the Middle Ages, with N1c.
balto-slavic-pca
Genetic structure of the Balto-Slavic populations within a European context according to the three genetic systems, from Kushniarevich et al. (2015). Pure Balto-Slavs from…hmm…yeah this…ancient…region…or people…cluster…Whatever, very very steppe-like peoples, the True Indo-Europeans™, so close to Yamna…almost as close as Finno-Ugrians.

To sum up: Iberia, Italy, France, the British Isles, central Europe, the Balkans, the Aegean, or Anatolia, all these territories can have a complex history of periodic admixture and language replacement everywhere, but some peoples appearing later than all others in the historical record (viz. Basques or Slavs) apparently cannot, because that would be shameful for their national or ethnic myths, and these should be respected.

Ignorance of the own past as a blank canvas to be filled in with stupid ethnolinguistic continuity, turned into something valuable that should not be challenged. Ethnonationalist-like reasoning proper of the 19th century. How can our times be called ‘modern’ when this kind of magical thinking is still prevalent, even among supposedly well-educated people?

ASoSaH Reread (II): Y-DNA haplogroups among Uralians (apart from R1a-M417)

corded-ware-yamna-ancestry

This is mainly a reread of from Book Two: A Game of Clans of the series A Song of Sheep and Horses: chapters iii.5. Early Indo-Europeans and Uralians, iv.3. Early Uralians, v.6. Late Uralians and vi.3. Disintegrating Uralians.

“Sredni Stog”

While the true source of R1a-M417 – the main haplogroup eventually associated with Corded Ware, and thus Uralic speakers – is still not known with precision, due to the lack of R1a-M198 in ancient samples, we already know that the Pontic-Caspian steppes were probably not it.

We have many samples from the north Pontic area since the Mesolithic compared to the Volga-Ural territory, and there is a clear prevalence of I2a-M223 lineages in the forest-steppe area, mixed with R1b-V88 (possibly a back-migration from south-eastern Europe).

R1a-M459 (xR1a-M198) lineages appear from the Mesolithic to the Chalcolithic scattered from the Baltic to the Caucasus, from the Dniester to Samara, in a situation similar to haplogroups Q1a-M25 and R1b-L754, which supports the idea that R1a, Q1a, and R1b expanded with ANE ancestry, possibly in different waves since the Epipalaeolithic, and formed the known ANE:EHG:WHG cline.

y-dna-khvalynsk
Y-DNA samples from Khvalynsk and neighbouring cultures. See full version.

The first confirmed R1a-M417 sample comes from Alexandria, roughly coinciding with the so-called steppe hiatus. Its emergence in the area of the previous “early Sredni Stog” groups (see the mess of the traditional interpretation of the north Pontic groups as “Sredni Stog”) and its later expansion with Corded Ware supports Kristiansen’s interpretation that Corded Ware emerged from the Dnieper-Dniester corridor, although samples from the area up to ca. 4000 BC, including the few Middle Eneolithic samples available, show continuity of hg. I2a-M223 and typical Ukraine Neolithic ancestry.

NOTE. The further subclade R1a-Z93 (Y26) reported for the sample from Alexandria seems too early, given the confidence interval for its formation (ca. 3500-2500 BC); even R1a-Z645 could be too early. Like the attribution of the R1b-L754 from Khvalynsk to R1b-V1636 (after being previously classifed as of Pre-V88 and M73 subclade), it seems reasonable to take these SNP calls with a pinch of salt: especially because Yleaf (designed to look for the furthest subclade possible) does not confirm for them any subclade beyond R1a-M417 and R1b-L754, respectively.

The sudden appearance of “steppe ancestry” in the region, with the high variability shown by Ukraine_Eneolithic samples, suggests that this is due to recent admixture of incoming foreign peoples (of Ukraine Neolithic / Comb Ware ancestry) with Novodanilovka settlers.

The most likely origin of this population, taking into account the most common population movements in the area since the Neolithic, is the infiltration of (mainly) hunter-gatherers from the forest areas. That would confirm the traditional interpretation of the origin of Uralic speakers in the forest zone, although the nature of Pontic-Caspian settlers as hunter-gatherers rather than herders make this identification today fully unnecessary (see here).

EDIT (3 FEB 2019): As for the most common guesstimates for Proto-Uralic, roughly coinciding with the expansion of this late Sredni Stog community (ca. 4000 BC), you can read the recent post by J. Pystynen in Freelance Reconstruction, Probing the roots of Samoyedic.

eneolithic-ukraine-corded-ware
Late Sredni Stog admixture shows variability proper of recent admixture of forest-steppe peoples with steppe-like population. See full version here.

NOTE. Although my initial simplistic interpretation (of early 2017) of Comb Ware peoples – traditionally identified as Uralic speakers – potentially showing steppe ancestry was probably wrong, it seems that peoples from the forest zone – related to Comb Ware or neighbouring groups like Lublyn-Volhynia – reached forest-steppe areas to the south and eventually expanded steppe ancestry into east-central Europe through the Volhynian Upland to the Polish Upland, during the late Trypillian disintegration (see a full account of the complex interactions of the Final Eneolithic).

The most interesting aspect of ascertaining the origin of R1a-M417, given its prevalence among Uralic speakers, is to precisely locate the origin of contacts between Late Proto-Indo-European and Proto-Uralic. Traditionally considered as the consequence of contacts between Middle and Upper Volga regions, the most recent archaeological research and data from ancient DNA samples has made it clear that it is Corded Ware the most likely vector of expansion of Uralic languages, hence these contacts of Indo-Europeans of the Volga-Ural region with Uralians have to be looked for in neighbours of the north Pontic area.

sredni-stog-repin-contacts
Sredni Stog – Repin contacts representing Uralic – Late Indo-European contacts were probably concentrated around the Don River.

My bet – rather obvious today – is that the Don River area is the source of the earliest borrowings of Late Uralic from Late Indo-European (i.e. post-Indo-Anatolian). The borrowing of the Late PIE word for ‘horse’ is particularly interesting in this regard. Later contacts (after the loss of the initial laryngeal) may be attributed to the traditionally depicted Corded Ware – Yamna contact zone in the Dnieper-Dniester area.

NOTE. While the finding of R1a-M417 populations neighbouring R1b-L23 in the Don-Volga interfluve would be great to confirm these contacts, I don’t know if the current pace of more and more published samples will continue. The information we have right now, in my opinion, suffices to support close contacts of neighbouring Indo-Europeans and Uralians in the Pontic-Caspian area during the Late Eneolithic.

Classical Corded Ware

After some complex movements of TRB, late Trypillia and GAC peoples, Corded Ware apparently emerged in central-east Europe, under the influence of different cultures and from a population that probably (at least partially) stemmed from the north Pontic forest-steppe area.

Single Grave and central Corded Ware groups – showing some of the earliest available dates (emerging likely ca. 3000/2900 BC) – are as varied in their haplogroups as it is expected from a sink (which does not in the least resemble the Volga-Ural population):

Interesting is the presence of R1b-L754 in Obłaczkowo, potentially of R1b-V88 subclade, as previously found in two Central European individuals from Blätterhole MN (ca. 3650 and 3200 BC), and in the Iron Gates and north Pontic areas.

Haplogroups I2a and G have also been reported in early samples, all potentially related to the supposed Corded Ware central-east European homeland, likely in southern Poland, a region naturally connected to the north Pontic forest-steppe area and to the expansion of Neolithic groups.

corded-ware-haplogroups
Y-DNA samples from early Corded Ware groups and neighbouring cultures. See full version.

The true bottlenecks under haplogroup R1a-Z645 seem to have happened only during the migration of Corded Ware to the east: to the north into the Battle Axe culture, mainly under R1a-Z282, and to the south into Middle Dnieper – Fatyanovo-Balanovo – Abashevo, probably eventually under R1a-Z93.

This separation is in line with their reported TMRCA, and supports the split of Finno-Permic from an eastern Uralic group (Ugric and Samoyedic), although still in contact through the Russian forest zone to allow for the spread of Indo-Iranian loans.

This bottleneck also supports in archaeology the expansion of a sort of unifying “Corded Ware A-horizon” spreading with people (disputed by Furholt), the disintegrating Uralians, and thus a source of further loanwords shared by all surviving Uralic languages.

Confirming this ‘concentrated’ Uralic expansion to the east is the presence of R1a-M417 (xR1a-Z645) lineages among early and late Single Grave groups in the west – which essentially disappeared after the Bell Beaker expansion – , as well as the presence of these subclades in modern Central and Western Europeans. Central European groups became thus integrated in post-Bell Beaker European EBA cultures, and their Uralic dialect likely disappeared without a trace.

NOTE. The fate of R1b-L51 lineages – linked to North-West Indo-Europeans undergoing a bottleneck in the Yamna Hungary -> Bell Beaker migration to the west – is thus similar to haplogroup R1a-Z645 – linked to the expansion of Late Uralians to the east – , hence proving the traditional interpretation of the language expansions as male-driven migrations. These are two of the most interesting genetic data we have to date to confirm previous language expansions and dialectal classifications.

It will be also interesting to see if known GAC and Corded Ware I2a-Y6098 subclades formed eventually part of the ancient Uralic groups in the east, apart from lineages which will no doubt appear among asbestos ware groups and probably hunter-gatherers from north-eastern Europe (see the recent study by Tambets et al. 2018).

Corded Ware ancestry marked the expansion of Uralians

Sadly, some brilliant minds decided in 2015 that the so-called “Yamnaya ancestry” (now more appropriately called “steppe ancestry”) should be associated to ‘Indo-Europeans’. This is causing the development of various new pet theories on the go, as more and more data contradicts this interpretation.

There is a clear long-lasting cultural, populational, and natural barrier between Yamna and Corded Ware: they are derived from different ancestral populations, which show clearly different ancestry and ancestry evolution (although they did converge to some extent), as well as different Y-DNA bottlenecks; they show different cultures, including those of preceding and succeeding groups, and evolved in different ecological niches. The only true steppe pastoralists who managed to dominate over grasslands extending from the Upper Danube to the Altai were Yamna peoples and their cultural successors.

NOTE. You can also read two recent posts by FrankN in the blog aDNA era, with detailed information on the Pontic-Caspian cultures and the formation of “steppe ancestry” during the Palaeolithic, Mesolithic and Neolithic: How did CHG get into Steppe_EMBA? Part 1: LGM to Early Holocene and How did CHG get into Steppe_EMBA? Part 2: The Pottery Neolithic. Unlike your typical amateur blogger on genetics using few statistical comparisons coupled with ‘archaeolinguoracial mumbo jumbo’ to reach unscientific conclusions, these are obviously carefully redacted texts which deserve to be read.

I will not enter into the discussion of “steppe ancestry” and the mythical “Siberian ancestry” for this post, though. I will just repost the opinion of Volker Heyd – an archaeologist specialized in Yamna Hungary and Bell Beakers who is working with actual geneticists – on the early conclusions based on “steppe ancestry”:

[A]rchaeologist Volker Heyd at the University of Bristol, UK, disagreed, not with the conclusion that people moved west from the steppe, but with how their genetic signatures were conflated with complex cultural expressions. Corded Ware and Yamnaya burials are more different than they are similar, and there is evidence of cultural exchange, at least, between the Russian steppe and regions west that predate Yamnaya culture, he says. None of these facts negates the conclusions of the genetics papers, but they underscore the insufficiency of the articles in addressing the questions that archaeologists are interested in, he argued. “While I have no doubt they are basically right, it is the complexity of the past that is not reflected,” Heyd wrote, before issuing a call to arms. “Instead of letting geneticists determine the agenda and set the message, we should teach them about complexity in past human actions.

Common pitfalls in human genomics and bioinformatics: ADMIXTURE, PCA, and the ‘Yamnaya’ ancestral component

invasion-from-the-steppe-yamnaya

Good timing for the publication of two interesting papers, that a lot of people should read very carefully:

ADMIXTURE

Open access A tutorial on how not to over-interpret STRUCTURE and ADMIXTURE bar plots, by Daniel J. Lawson, Lucy van Dorp & Daniel Falush, Nature Communications (2018).

Interesting excerpts (emphasis mine):

Experienced researchers, particularly those interested in population structure and historical inference, typically present STRUCTURE results alongside other methods that make different modelling assumptions. These include TreeMix, ADMIXTUREGRAPH, fineSTRUCTURE, GLOBETROTTER, f3 and D statistics, amongst many others. These models can be used both to probe whether assumptions of the model are likely to hold and to validate specific features of the results. Each also comes with its own pitfalls and difficulties of interpretation. It is not obvious that any single approach represents a direct replacement as a data summary tool. Here we build more directly on the results of STRUCTURE/ADMIXTURE by developing a new approach, badMIXTURE, to examine which features of the data are poorly fit by the model. Rather than intending to replace more specific or sophisticated analyses, we hope to encourage their use by making the limitations of the initial analysis clearer.

The default interpretation protocol

Most researchers are cautious but literal in their interpretation of STRUCTURE and ADMIXTURE results, as caricatured in Fig. 1, as it is difficult to interpret the results at all without making several of these assumptions. Here we use simulated and real data to illustrate how following this protocol can lead to inference of false histories, and how badMIXTURE can be used to examine model fit and avoid common pitfalls.

admixture-protocol
A protocol for interpreting admixture estimates, based on the assumption that the model underlying the inference is correct. If these assumptions are not validated, there is substantial danger of over-interpretation. The “Core protocol” describes the assumptions that are made by the admixture model itself (Protocol 1, 3, 4), and inference for estimating K (Protocol 2). The “Algorithm input” protocol describes choices that can further bias results, while the “Interpretation” protocol describes assumptions that can be made in interpreting the output that are not directly supported by model inference

Discussion

STRUCTURE and ADMIXTURE are popular because they give the user a broad-brush view of variation in genetic data, while allowing the possibility of zooming down on details about specific individuals or labelled groups. Unfortunately it is rarely the case that sampled data follows a simple history comprising a differentiation phase followed by a mixture phase, as assumed in an ADMIXTURE model and highlighted by case study 1. Naïve inferences based on this model (the Protocol of Fig. 1) can be misleading if sampling strategy or the inferred value of the number of populations K is inappropriate, or if recent bottlenecks or unobserved ancient structure appear in the data. It is therefore useful when interpreting the results obtained from real data to think of STRUCTURE and ADMIXTURE as algorithms that parsimoniously explain variation between individuals rather than as parametric models of divergence and admixture.

For example, if admixture events or genetic drift affect all members of the sample equally, then there is no variation between individuals for the model to explain. Non-African humans have a few percent Neanderthal ancestry, but this is invisible to STRUCTURE or ADMIXTURE since it does not result in differences in ancestry profiles between individuals. The same reasoning helps to explain why for most data sets—even in species such as humans where mixing is commonplace—each of the K populations is inferred by STRUCTURE/ADMIXTURE to have non-admixed representatives in the sample. If every individual in a group is in fact admixed, then (with some exceptions) the model simply shifts the allele frequencies of the inferred ancestral population to reflect the fraction of admixture that is shared by all individuals.

Several methods have been developed to estimate K, but for real data, the assumption that there is a true value is always incorrect; the question rather being whether the model is a good enough approximation to be practically useful. First, there may be close relatives in the sample which violates model assumptions. Second, there might be “isolation by distance”, meaning that there are no discrete populations at all. Third, population structure may be hierarchical, with subtle subdivisions nested within diverged groups. This kind of structure can be hard for the algorithms to detect and can lead to underestimation of K. Fourth, population structure may be fluid between historical epochs, with multiple events and structures leaving signals in the data. Many users examine the results of multiple K simultaneously but this makes interpretation more complex, especially because it makes it easier for users to find support for preconceptions about the data somewhere in the results.

In practice, the best that can be expected is that the algorithms choose the smallest number of ancestral populations that can explain the most salient variation in the data. Unless the demographic history of the sample is particularly simple, the value of K inferred according to any statistically sensible criterion is likely to be smaller than the number of distinct drift events that have practically impacted the sample. The algorithm uses variation in admixture proportions between individuals to approximately mimic the effect of more than K distinct drift events without estimating ancestral populations corresponding to each one. In other words, an admixture model is almost always “wrong” (Assumption 2 of the Core protocol, Fig. 1) and should not be interpreted without examining whether this lack of fit matters for a given question.

admixture-pitfalls
Three scenarios that give indistinguishable ADMIXTURE results. a Simplified schematic of each simulation scenario. b Inferred ADMIXTURE plots at K= 11. c CHROMOPAINTER inferred painting palettes.

Because STRUCTURE/ADMIXTURE accounts for the most salient variation, results are greatly affected by sample size in common with other methods. Specifically, groups that contain fewer samples or have undergone little population-specific drift of their own are likely to be fit as mixes of multiple drifted groups, rather than assigned to their own ancestral population. Indeed, if an ancient sample is put into a data set of modern individuals, the ancient sample is typically represented as an admixture of the modern populations (e.g., ref. 28,29), which can happen even if the individual sample is older than the split date of the modern populations and thus cannot be admixed.

This paper was already available as a preprint in bioRxiv (first published in 2016) and it is incredible that it needed to wait all this time to be published. I found it weird how reviewers focused on the “tone” of the paper. I think it is great to see files from the peer review process published, but we need to know who these reviewers were, to understand their whiny remarks… A lot of geneticists out there need to develop a thick skin, or else we are going to see more and more delays based on a perceived incorrect tone towards the field, which seems a rather subjective reason to force researchers to correct a paper.

PCA of SNP data

Open access Effective principal components analysis of SNP data, by Gauch, Qian, Piepho, Zhou, & Chen, bioRxiv (2018).

Interesting excerpts:

A potential hindrance to our advice to upgrade from PCA graphs to PCA biplots is that the SNPs are often so numerous that they would obscure the Items if both were graphed together. One way to reduce clutter, which is used in several figures in this article, is to present a biplot in two side-by-side panels, one for Items and one for SNPs. Another stratagem is to focus on a manageable subset of SNPs of particular interest and show only them in a biplot in order to avoid obscuring the Items. A later section on causal exploration by current methods mentions several procedures for identifying particularly relevant SNPs.

One of several data transformations is ordinarily applied to SNP data prior to PCA computations, such as centering by SNPs. These transformations make a huge difference in the appearance of PCA graphs or biplots. A SNPs-by-Items data matrix constitutes a two-way factorial design, so analysis of variance (ANOVA) recognizes three sources of variation: SNP main effects, Item main effects, and SNP-by-Item (S×I) interaction effects. Double-Centered PCA (DC-PCA) removes both main effects in order to focus on the remaining S×I interaction effects. The resulting PCs are called interaction principal components (IPCs), and are denoted by IPC1, IPC2, and so on. By way of preview, a later section on PCA variants argues that DC-PCA is best for SNP data. Surprisingly, our literature survey did not encounter even a single analysis identified as DC-PCA.

The axes in PCA graphs or biplots are often scaled to obtain a convenient shape, but actually the axes should have the same scale for many reasons emphasized recently by Malik and Piepho [3]. However, our literature survey found a correct ratio of 1 in only 10% of the articles, a slightly faulty ratio of the larger scale over the shorter scale within 1.1 in 12%, and a substantially faulty ratio above 2 in 16% with the worst cases being ratios of 31 and 44. Especially when the scale along one PCA axis is stretched by a factor of 2 or more relative to the other axis, the relationships among various points or clusters of points are distorted and easily misinterpreted. Also, 7% of the articles failed to show the scale on one or both PCA axes, which leaves readers with an impressionistic graph that cannot be reproduced without effort. The contemporary literature on PCA of SNP data mostly violates the prohibition against stretching axes.

pca-how-to
DC-PCA biplot for oat data. The gradient in the CA-arranged matrix in Fig 13 is shown here for both lines and SNPs by the color scheme red, pink, black, light green, dark green.

The percentage of variation captured by each PC is often included in the axis labels of PCA graphs or biplots. In general this information is worth including, but there are two qualifications. First, these percentages need to be interpreted relative to the size of the data matrix because large datasets can capture a small percentage and yet still be effective. For example, for a large dataset with over 107,000 SNPs for over 6,000 persons, the first two components capture only 0.3693% and 0.117% of the variation, and yet the PCA graph shows clear structure (Fig 1A in [4]). Contrariwise, a PCA graph could capture a large percentage of the total variation, even 50% or more, but that would not guarantee that it will show evident structure in the data. Second, the interpretation of these percentages depends on exactly how the PCA analysis was conducted, as explained in a later section on PCA variants. Readers cannot meaningfully interpret the percentages of variation captured by PCA axes when authors fail to communicate which variant of PCA was used.

Conclusion

Five simple recommendations for effective PCA analysis of SNP data emerge from this investigation.

  1. Use the SNP coding 1 for the rare or minor allele and 0 for the common or major allele.
  2. Use DC-PCA; for any other PCA variant, examine its augmented ANOVA table.
  3. Report which SNP coding and PCA variant were selected, as required by contemporary standards in science for transparency and reproducibility, so that readers can interpret PCA results properly and reproduce PCA analyses reliably.
  4. Produce PCA biplots of both Items and SNPs, rather than merely PCA graphs of only Items, in order to display the joint structure of Items and SNPs and thereby to facilitate causal explanations. Be aware of the arch distortion when interpreting PCA graphs or biplots.
  5. Produce PCA biplots and graphs that have the same scale on every axis.

I read the referenced paper Biplots: Do Not Stretch Them!, by Malik and Piepho (2018), and even though it is not directly applicable to the most commonly available PCA graphs out there, it is a good reminder of the distorting effects of stretching. So for example quite recently in Krause-Kyora et al. (2018), where you can see Corded Ware and BBC samples from Central Europe clustering with samples from Yamna:

NOTE. This is related to a vertical distorsion (i.e. horizontal stretching), but possibly also to the addition of some distant outlier sample/s.

The so-called ‘Yamnaya’ ancestry

Every time I read papers like these, I remember commenters who kept swearing that genetics was the ultimate science that would solve anthropological problems, where unscientific archaeology and linguistics could not. Well, it seems that, like radiocarbon analysis, these promising developing methods need still a lot of refinement to achieve something meaningful, and that they mean nothing without traditional linguistics and archaeology… But we already knew that.

Also, if this is happening in most peer-reviewed publications, made by professional geneticists, in journals of high impact factor, you can only wonder how many more errors and misinterpretations can be found in the obscure market of so many amateur geneticists out there. Because amateur geneticist is a commonly used misnomer for people who are not geneticists (since they don’t have the most basic education in genetics), and some of them are not even ‘amateurs’ (because they are selling the outputs of bioinformatic tools)… It’s like calling healers ‘amateur doctors’.

NOTE. While everyone involved in population genetics is interested in knowing the truth, and we all have our confirmation (and other kinds of) biases, for those who get paid to tell people what they want to hear, and who have sold lots of wrong interpretations already, the incentives of ‘being right’ – and thus getting involved in crooked and paranoid behaviour regarding different interpretations – are as strong as the money they can win or loose by promoting themselves and selling more ‘product’.

As a reminder of how badly these wrong interpretations of genetic results – and the influence of the so-called ‘amateurs’ – can reflect on research groups, yet another turn of the screw by the Copenhagen group, in the oral presentations at Languages and migrations in pre-historic Europe (7-12 Aug 2018), organized by the Copenhagen University. The common theme seems to be that Bell Beaker and thus R1b-L23 subclades do represent a direct expansion from Yamna now, as opposed to being derived from Corded Ware migrants, as they supported before.

NOTE. Yes, the “Yamna → Corded Ware → Únětice / Bell Beaker” migration model is still commonplace in the Copenhagen workgroup. Yes, in 2018. Guus Kroonen had already admitted they were wrong, and it was already changed in the graphic representation accompanying a recent interview to Willerslev. However, since there is still no official retraction by anyone, it seems that each member has to reject the previous model in their own way, and at their own pace. I don’t think we can expect anyone at this point to accept responsibility for their wrong statements.

So their lead archaeologist, Kristian Kristiansen, in The Indo-Europeanization of Europé (sic):

kristiansen-migrations
Kristiansen’s (2018) map of Indo-European migrations

I love the newly invented arrows of migration from Yamna to the north to distinguish among dialects attributed by them to CWC groups, and the intensive use of materials from Heyd’s publications in the presentation, which means they understand he was right – except for the fact that they are used to support a completely different theory, radically opposed to those defended in Heyd’s model

Now added to the Copenhagen’s unending proposals of language expansions, some pearls from the oral presentation:

  • Corded Ware north of the Carpathians of R1a lineages developed Germanic;
  • R1b borugh [?] Italo-Celtic;
  • the increase in steppe ancestry on north European Bell Beakers mean that they “were a continuation of the Yamnaya/Corded Ware expansion”;
  • Corded Ware groups [] stopped their expansion and took over the Bell Beaker package before migrating to England” [yep, it literally says that];
  • Italo-Celtic expanded to the UK and Iberia with Bell Beakers [I guess that included Lusitanian in Iberia, but not Messapian in Italy; or the opposite; or nothing like that, who knows];
  • 2nd millennium BC Bronze Age Atlantic trade systems expanded Proto-Celtic [yep, trade systems expanded the language]
  • 1st millennium BC expanded Gaulish with La Tène, including a “Gaulish version of Celtic to Ireland/UK” [hmmm, dat British Gaulish indeed].

You know, because, why the hell not? A logical, stable, consequential, no-nonsense approach to Indo-European migrations, as always.

Also, compare still more invented arrows of migrations, from Mikkel Nørtoft’s Introducing the Homeland Timeline Map, going against Kristiansen’s multiple arrows, and even against the own recent fantasy map series in showing Bell Beakers stem from Yamna instead of CWC (or not, you never truly know what arrows actually mean):

corded-ware-migrations
Nørtoft’s (2018) maps of Indo-European migrations.

I really, really loved that perennial arrow of migration from Volosovo, ca. 4000-800 BC (3000+ years, no less!), representing Uralic?, like that, without specifics – which is like saying, “somebody from the eastern forest zone, somehow, at some time, expanded something that was not Indo-European to Finland, and we couldn’t care less, except for the fact that they were certainly not R1a“.

This and Kristiansen’s arrows are the most comical invented migration routes of 2018; and that is saying something, given the dozens of similar maps that people publish in forums and blogs each week.

NOTE. You can read a more reasonable account of how haplogroup R1b-L51 and how R1-Z645 subclades expanded, and which dialects most likely expanded with them.

We don’t know where these scholars of the Danish workgroup stand at this moment, or if they ever had (or intended to have) a common position – beyond their persistent ideas of Yamnaya™ ancestral component = Indo-European and R1a must be Indo-European – , because each new publication changes some essential aspects without expressly stating so, and makes thus everything still messier.

It’s hard to accept that this is a series of presentations made by professional linguists, archaeologists, and geneticists, as stated by the official website, and still harder to imagine that they collaborate within the same professional workgroup, which includes experienced geneticists and academics.

I propose the following video to close future presentations introducing innovative ideas like those above, to help the audience find the appropriate mood:

On the origin and spread of haplogroup R1a-Z645 from eastern Europe

indo-european-uralic-migrations-corded-ware

In my recent post about the origin and expansion of haplogroup R1b-L51, Chetan made an interesting comment on the origin and expansion of R1a-Z645. Since this haplogroup is also relevant for European history and dialectal North-West Indo-European and Indo-Iranian expansion, I feel compelled to do a similar post, although the picture right now is more blurry than that of R1b-L51.

I find it interesting that many geneticists would question the simplistic approach to the Out of Africa model as it is often enunciated, but they would at the same time consider the current simplistic model of Yamna expansion essentially right; a model – if anyone is lost here – based on proportions of the so-called Yamnaya™ ancestral component, as found in a small number of samples, from four or five Eneolithic–Chalcolithic cultures spanning more than a thousand years.

The “75% Yamnaya ancestry of Corded Ware”, which has been given so much publicity since 2015, made geneticists propose a “Yamna → Corded Ware → Únětice / Bell Beaker” migration model, in order of decreasing Yamnaya proportions. Y-DNA and solid archaeological models suggested that this model was wrong, and recent findings have proven it was. In fact, the CWC sample closest to Yamna was a late outlier of Esperstedt in Central Europe, whose ancestry is most likely directly related to Yamna settlers from Hungary.

These wrong interpretations have been now substituted by data from two new early samples from the Baltic, which cluster closely to Yamna, and which – based on the Y-DNA and PCA cluster formed by all Corded Ware samples – are likely the product of female exogamy with Yamna peoples from the neighbouring North Pontic region (as we are seeing, e.g. in the recent Nikitin et al. 2018).

NOTE. There is also another paper from Nikitin et al. (2017), with more ancient mtDNA, “Subdivisions of haplogroups U and C encompass mitochondrial DNA lineages of Eneolithic-Early Bronze Age Kurgan populations of western North Pontic steppe”. Link to paper (behind paywall). Most interesting data is summarized in the following table:

yamna-corded-ware-mtdna

Even after the publication of Olalde et al. (2018) and Wang et al. (2018) – where expanding Yamna settlers and Bell Beakers are clearly seen highly admixed within a few generations, and are found spread across a wide Eurasian cline (sharing one common invariable trait, the paternally inherited haplogroup, as supported by David Reich) – fine-scale studies of population structure and social dynamics is still not a thing for many, even though it receives more and more advocates among geneticists (e.g. Lazaridis, or Veeramah).

NOTE. I have tried to explain, more than once, that the nature and origin of the so-called “Yamnaya ancestry” (then “steppe ancestry”, and now subdivided further as Steppe_EMBA and Steppe_MLBA) is not known with precision before Yamna samples of ca. 3000 BC, and especially that it is not necessarily a marker of Indo-European speakers. Why some people are adamant that steppe ancestry and thus R1a must be Indo-European is mostly related to a combination of grandaddy’s haplogroup, the own modern ethnolinguistic attribution, and an aversion to sharing grandpa with other peoples and cultures.

In the meantime, we are seeing the “Yamnaya proportion” question often reversed: “how do we make Corded Ware stem from Yamna, now that we believed it?”. This is a funny circular reasoning, akin to the one used by proponents of the Franco-Cantabrian origin of R1b, when they look now at EEF proportions in Iberian R1b-L23 samples. It seems too comic to be true.

R1a and steppe ancestry

The most likely origin of haplogroup R1a-Z645 is to be found in eastern Europe. Samples published in the last year support this region as a sort of cradle of R1a expansions:

  • I1819, Y-DNA R1a1-M459, mtDNA U5b2, Ukraine Mesolithic ca. 8825-8561 calBCE, from Vasilievka.
  • I5876, Y-DNA R1a, mtDNA U5a2a, Ukraine Mesolithic 7040-6703 calBCE, from Dereivka.
  • I0061, hg R1a1-M459 (xR1a1a-M17), mtDNA C1, ca. 6773-6000 calBCE (with variable dates), from Yuzhnyy Oleni Ostrov in Karelia.
  • Samples LOK_1980.006 and LOK_1981.024.01, of hg MR1a1a-M17, mtDNA F, Baikalic cultures, dated ca. 5500-5000 BC.
  • Sample I0433, hg R1a1-M459(xM198), mtDNA U5a1i, from Samara Eneolithic, ca. 5200-4000 BCE
  • Samples A3, A8, A9, of hg R1a1-M459, mtDNA H, from sub-Neolithic cultures (Comb Ware and Zhizhitskaya) at Serteyea, although dates (ca. 5th-3rd millennium BC) need possibly a revision (from Chekunova 2014).

NOTE. The fact that Europe is better sampled than North Asia, coupled with the finding of R1a-M17 in Baikalic cultures, poses some problems as to the precise origin of this haplogroup and its subclades. While the first (Palaeolithic or Mesolithic) expansion was almost certainly from Northern Eurasia to the west – due to the Mal’ta sample – , it is still unknown if the different subclades of R1a in Europe are the result of local developments, or rather different east—west migrations through North Eurasia.

Y-Full average estimates pointed to R1a-M417 formation ca. 6500 BC, TMRCA ca. 3500 BC, and R1a-Z645 formation ca. 3300 BC, TMRCA ca. 2900 BC, so the most likely explanation was that R1a-Z645 and its subclades – similar to R1b-L23 subclades, but slightly later) expanded quickly with the expansion of Corded Ware groups.

The presence of steppe ancestry in Ukraine Eneolithic sample I6561, of haplogroup R1a-M417, from Alexandria, dated ca. 4045-3974 calBCE, pointed to the forest steppe area and late Sredni Stog as the most likely territory from where the haplogroup related to the Corded Ware culture expanded.

However, the more recent Y-SNP call showing R1a-Z93 (L657) subclade rendered Y-Full’s (at least formation) estimates too young, so we have to rethink the actual origin of both subclades, R1a-Z93 (formation ca. 2900 BC, TMRCA ca 2700 BC), and R1a-Z283 (formation ca. 2900 BC, TMRCA ca. 2800 BC).

Contrary to what we thought before this, then, it is possible that the expansion of Khvalynsk-Novodanilovka chieftains through the steppes, around the mid-5th millennium BC, had something to do with the expansion of R1a-Z645 to the north, in the forest steppe.

We could think that the finding of Z93 in Alexandria after the expansion of Khvalynsk-Novodanilovka chiefs would make it more likely that R1a-Z645 will be found in the North Pontic area. However, given that Lower Mikhailovka and Kvitjana seem to follow a steppe-related cultural tradition, different to forest steppe cultures (like Dereivka and Alexandria), and that forest steppe cultures show connections to neighbouring northern and western forest regions, the rest of the expanding R1a-Z645 community may not be related directly to the steppe at all.

Adding a hypothetical split and expansion of Z645 subclades to the mid-/late-5th millennium could place the expansion of this haplogroup to the north and west, pushed by expanding Middle PIE-speaking steppe peoples from the east:

The Złota culture

I have already written about the Podolia-Volhynia region: about the North Pontic steppe cultures in contact with this area, and about the chaotic period of migrations when Corded Ware seem to have first emerged there among multi-directional and multi-ethnic migrants.

This is what Włodarczak (2017) says about the emergence of Corded Ware with ‘steppe features’ after the previous expansion of such features in Central Europe with Globular Amphorae peoples. He refers here to the Złota culture (appearing ca. 2900-2800 BC) in Lesser Poland, believed to be the (or a) transitional stage between GAC and Corded Ware, before the emergence of the full-fledged “Corded Ware package”.

So far, to the north of the Carpathian Mountains, including Polish lands, no graves indicating their relationship with communities of the steppe zone have been found. On the contrary, the funeral rites always display a local, central European nature. However, individual elements typical of steppe communities do appear, such as the “frog-like” arrangement of the body (Fig. 20), or items associated with Pit Grave milieux (cf. Klochko, Kośko 2009; Włodarczak 2014). A spectacular example of the latter is the pointed-base vessel of Pit Grave culture found at the cemetery in Święte, site 11 near Jarosław (Kośko et al. 2012). These finds constitute a confirmation of the importance of the relationships between communities of Pit Grave culture and Corded Ware culture. They are chronologically diverse, although most of them are dated to 2600-2400 BC – that is, to the “classic” period of Corded Ware culture.

funnelbeaker-trypillia-corded-ware
Map of territorial ranges of Funnel Beaker Culture (and its settlement concentrations in Lesser Poland), local Trypillian groups and early Corded Ware Culture settlements (◼) at the turn of the 4th/3rd millennia BC.

However, when discussing the relationships with the steppe communities, Polish lands deserve particular attention since part of the groups inhabiting it belonged to the eastern province of Corded Ware culture (cf. Häusler 2014), which neighboured Pit Grave culture both from the east and south. In addition, there was a tradition of varied relationships with the north Pontic zone, which began to intensify from the second half of the 4th millennium BC (Kośko, Szmyt, 2009; Kośko, Klochko, 2009). These connections are especially readable in Małopolska and Kujawy (Kośko 2014; Włodarczak 2014). The emergence of the community of Globular Amphora culture in the north Pontic zone at the end of the 4th and the beginnings of the 3rd millennium BC (Szmyt 1999) became a harbinger of a cultural closening between the worlds of central Europe and the steppe.

The second important factor taking place at that time was the expansion of the people of Pit Grave culture in a westerly direction, along the Danube thoroughfare. As a result of this, also to the south of the Carpathian Mountains, e.g., along the upper Tisza River, a new “kurgan” cultural system was formed. As one outcome, the areas of central Europe, above all Małopolska, found themselves in the vicinity of areas inhabited by communities characterized by new principles of social organization and a new funeral rite. Around 2800 BC these changes became evident in different regions of Poland, with the most numerous examples being documented in south-eastern Poland and Kujawy. The nature of the funeral rite and the features of the material culture perceptible at that time do not have straight forward analogies in the world of north Pontic communities. In this respect, the “A-horizon” is a phenomenon of local, central European origin. The events preceding the emergence of the said horizon (that is, the expansion of the people of Pit Grave culture into the area north of the arc of the Carpathians) are nowadays completely unidentifiable and remain merely an interesting theoretical matter (cf. e.g., Kośko 2000). Therefore, analysis of the archaeological sources cannot confirm the first archaeogenetic analysis suggesting a bond between the communities of the Pit Grave culture and Corded Ware culture (e.g., Haak et al. 2015).

Artefacts of the “A-horizon”, i.e., shaft-hole axes, amphorae (Fig. 21), beakers, and pots with a plastic wavy strip (Fig. 7) are found in different funerary and settlement contexts, sometimes jointly with finds having characteristics of various cultures (e.g., in graves of Złota culture, or at settlements of Rzucewo culture). Hence, they primarily represent a chronological phase (c. 2800-2600 BC), one obviously related to the expansion of a new ideology.

Eastern CWC expansion

Before continuing tracing the Corded Ware culture’s main features, it is worth it to trace first their movement forward in time, as Corded Ware settlers, from Poland to the east.

Circum-Baltic CWC

According to Klochko and Kośko (1998):

The colonizing Neolithic waves are continued by the Circum-Baltic Corded Ware culture, closely related to the traditions of the Single Grave culture and traditions of the Northern European Lowlands. After ca. 2900 BC, certain cultural systems with ‘corded’ traits –genetically related to the catchment area of the south-western Baltic – appear in the drainages of the Nemen, Dvina, Upper Dnieper, and even the Volga. These communities are considered the vector of Neolithisation in the Forest Zone.

The picture in the Baltic (Pamariu / Rzucewo) and Finland (Battle Axe) is thus more or less clearly connected with early dates ca. 2900-2800 BC:

There is a clear interaction sphere between the eastern Gulf of Finland area – reaching from Estonia to the areas of present-day Finland and the Karelian Isthmus in Russia –, evidenced e.g. by the sharp-butted axes, derived from the Estonian Karlova axe.

Interesting in this regard is the expansion of the Corded Ware culture in Finland, into a far greater territory than previously thought, that is poorly represented in most maps depicting the extent of the culture in Europe. Here is summary of CWC findings in Finland, using images from Nordqvist and Häkäla (2014):

Middle Dnieper and Fatyanovo

The earliest Middle Dnieper remains are related to CWC graves between the Upper Vistula and the Bug, containing pottery with Middle Dnieper traits, dated probably ca. 2700 BC, which links it with the expansion of the A-horizon. In fact, during the period ca. 2800-2400 BC, the area of Lesser Poland (with its numerous kurgans and catacomb burials) is considered the western fringe of an area spreading to the east, to the middle Dniester and middle Dnieper river basins, i.e. regions bordering the steppe oecumene. This ‘eastern connection’ of funeral ritual, raw materials, and stylistic traits of artefacts is also identified in some graves of the Polish Lowlands (Włodarczak 2017).

From Szmyt (2010)

The Fatyanovo (or Fatyanovo-Balanovo) culture was the easternmost group of the Corded Ware culture, and occupied the centre of the Russian Plain, from Lake Ilmen and the Upper Dnieper drainage to the Wiatka River and the middle course of the Volga. From the few available dates, the oldest ones from the plains of the Moskva river, and from the late Volosovo culture containing also Fatyanovo materials, and in combination they show a date of ca. 2700 BC for its appearance in the region. The Volosovo culture of foragers eventually disappeared when the Fatyanovo culture expanded into the Upper and Middle Volga basin.

The origin of the culture is complicated, because it involves at its earliest stage different Corded Ware influences in neighbouring sites, at least on the Moskva river plains (Krenke et al. 2013): some materials (possibly earlier) show Circum-Baltic and Polish features; other sites show a connection to western materials, in turn a bridge to the Middle Dnieper culture. This suggests that groups belonging to different groups of the corded ware tradition penetrated the Moscow region.

The split of subclades Z93 – Z283

If we take into account that the split between R1-Z93 and R1a-Z283 must have happened during the 5th millennium BC, we have R1a-Z93 likely around the middle Dnieper area (as supported by the Alexandria sample), and R1a-Z283 possibly to the north(-west), so that it could have expanded easily into Central Europe, and – through the northern, Baltic region – to the east.

Where exactly lies the division is unclear, but for the moment all reported Circum-Baltic samples with Z645 subclades seem to belong to Z282, while R1a samples from Sintashta/Potapovka (including the Poltavka outlier) point to Abashevo being dominated by R1a-Z93 subclades.

We have to assume, then, that an original east-west split betwen R1a-Z283 and R1a-Z93 turned, in the eastern migrations, into a north-south split between Z282 and Z93, where Finland and Battle Axe in general is going to show Z282, and Middle Dnieper – Abashevo Z93 subclades.

copper-age-early-cwc
Early Copper Age migrations ca. 3100-2600 BC.

I can think of two reasons why this is important:

  1. Depending on how Proto-Corded Ware peoples expanded, we may be talking about one community overcoming the other and imposing its language. Because either
    • clans of both Z93 and Z283 were quite close and kept intense cultural contacts around Dnieper-Dniester area; or
    • if the split is as early as the 5th millennium BC, and both communities separated then without contact, we are probably going to see a difference in the language spoken by both of them.
  2. In any case, the main north-south division of eastern Corded Ware groups is pointing to an important linguistic division within the Uralic-speaking communities, specifically between a Pre-Finno-Ugric and a Pre-Samoyedic one, and potentially between Pre-Finno-Permic and Pre-Ugric.

These may seem irrelevant questions – especially for people interested only in Indo-European migrations. However, for those interested in the history of Eurasian peoples and languages as a whole, they are relevant: even those who support an ‘eastern’ origin of Proto-Uralic, like Häkkinen, or Parpola (who are, by the way, in the minority, because most Uralicists would point to eastern Europe well before the Yamna expansion), place the Finno-Ugric expansion with the Netted Ware culture as the latest possible Finno-Ugric immigrants in Fennoscandia.

The Netted Ware culture

The image below shows the approximate expansion of Corded Ware peoples of Battle Axe traditions in Finland, as well as neighbouring Fennoscandian territories, from ca. 2800 BC until the end of the 3rd millennium. A controversial 2nd (late) wave of the so-called Estonian Corded Ware is popular in texts about this region, but has not been substantiated, and it seems to be a regional development, rather than the product of migrations.

Mapped (black dots) are finds of typical stone battle axes, used as a proxy (data from [8]). The red isolines indicate average permanent snow cover period from 1981 to 2010 (data from [9]). A recent study estimates the snow cover period ca 4500 years ago would have been 40–50 days less than today [10]. Overlying coloration refers to the lactose persistance (LP) allele gradient in modern northeastern Europe (see the electronic supplementary material, appendix B: Material and methods and table 1, for details); lozenge dots specify the dataset mean points for the triangulation. From Cramp et al. (2014).

As we have seen, Fatyanovo represents the most likely cultural border zone between Circum-Baltic peoples reaching from the Russian Battle Axe to the south, and Middle Dnieper peoples reaching from Abashevo to the north. In that sense, it also represents the most likely border culture between north-western (mainly R1a-Z282) and south-eastern (R1a-Z93) subclades.

With worsening climatic conditions (cooler seasons) at the end of the 3rd millennium, less settlements are apparent in the archaeological record in Finland. After ca. 2000 BC, two CWC-related cultures remain: in the coast, the Kiukainen culture, derived from the original Circum-Baltic Corded Ware settlers, reverts to a subsistence economy which includes hunting and fishing, and keeps mainly settlements (from the best territories) along the coast. In the inland, Netted Ware immigrants eventually appear from the south.

discussed here alongside actual sherds sampled and typical vessel forms (after [26–28]) (latter not shown to scale). Distribution maps show the geographical range of (f) Typical Comb Ware, (g) Corded Ware, (h) Kiukainen Ware and (i) Bronze Age cultures in the region (after [10,20,29]).”

The Netted Ware culture emerged in the Upper Volga–Oka region, derived from the Abashevo culture and its interaction with the Seima-Turbino network, and spread ca. 1900-1800 BC to the north into Finland, spreading into eastern regions previously occupied by cultures producing asbestos and organic-tempered wares (Parpola 2018).

NOTE. Those ‘contaminated’ by the Copenhagen fantasy map series may think that Volosovo hunter-gatherers somehow survived the expansion of Fatyanovo-Balanovo and Abashevo, hidden for hundreds of years in the forest, and then reappeared and expanded the Netted Ware culture. Well, they didn’t. At least not in archaeological terms, and certainly not with the genetic data we have.

If we combine all this information, and we think about these peoples in terms of Pre-Finno-Permic and Pre-Ugric languages developing side by side, we get a really interesting picture (see here for Proto-Fennic estimates):

  • The Battle Axe around the Baltic Sea – including the Gulf of Finland and Scandinavia – would be the area of expansion of Pre-Finno-Permic peoples, of R1a-Z283 subclades, which became later concentrated mainly on coastal regions;
  • the southern areas may correspond to Pre-Ugric peoples, which expanded later to the north with Netted Ware (see image below) – their precise subclades may be dependent on what will be found in Fatyanovo;
  • and Pre-Samoyedic peoples (of R1a-Z93 subclades) would have become isolated somewhere in the Cis- or (more likely) Trans-Urals region after 2000 BC, possibly from the interaction of the latest Balanovo stages and the Seima-Turbino phenomenon.

Distribution of the Netted Ware according to Carpelan (2002: 198). A: Emergence of the Netted Ware on the Upper Volga c. 1900 calBC. B: Spread of Netted Ware by c. 1800 calBC. C: Early Iron Age spread of Netted Ware. (After Carpelan 2002: 198 > Parpola 2012a: 151.)

These communities in contact would have allowed for:

  • the known Indo-Iranian loanwords in Finno-Ugric to spread through a continuum of early dialects formed by Abashevo – Fatyanovo – Battle Axe groups;
  • the Finno-Saamic substrate of Germanic to be associated with Battle Axe groups in Scandinavia;
  • the important Palaeo-Germanic loanwords in Finno-Saamic spreading with long-term contacts (from Pre-Germanic to the Proto-Germanic, and later North Germanic period) through the Baltic Sea, between Scandinavia and the Gulf of Finland;
  • and Tocharian contacts with Samoyedic (although limited, and in part controversial), which point to its early expansion to the east of the Ural Mountains.

On the other hand, if one is inclined to believe that R1a and steppe ancestry do represent Indo-European speakers… which language was spoken from the Gulf of Finland well into the north, the inland, and Karelia, and in Northern Russia, by Corded Ware peoples and their cultural heirs (like Kiukainen or Netted Ware) for almost three thousand years?

Because we know that no other peoples of different haplogroups dominated over eastern Fennoscandia until the Iron Age, and N1c and Siberian ancestry expanded separately, and probably due to late bottlenecks, especially with Fennic peoples expanding recently to the north at the expense of the Saami population.

After the expansion of Bell Beaker peoples, the geographic distribution of late Corded Ware groups in the second half of the 3rd millennium, just before their demise – and before the expansion of Netted Ware to the north – , can be depicted thus as follows:

bronze_age_early_cut
Early Bronze Age Europe.

Territories in cyan must then represent, for some people who believe in an archaic Indo-Slavonic of sorts, the famous Fennoscandian Balto-Slavic to the north (before they were displaced by incoming Finno-Saamic peoples of hg N1c during the Iron Age and up to the Middle Ages); and the also famous Tundra-Forest Indo-Iranian in the Upper Volga area, a great environment for the development of the two-wheeled chariot…

But let’s leave the discussion on imaginary IE dialects for another post, and continue with the real question at hand.

A steppe funerary connection?

Back to Złota as a transitional culture, we have already seen how the corded ware vessels characteristic of the Classic CWC are related to Globular Amphora tradition, and show no break with this culture. It is usually believed that the funerary rites were adopted from steppe influence, too. That is probably right; but it does not mean that it came from Yamna or other coeval (or previous) steppe culture; at least not directly.

NOTE. A similar problem is seen when we read that Mierzanowice or Trzciniec show “Corded Ware” traits from a neighbouring CWC group, when CWC groups disappeared long before these cultures emerged. For cultural groups that are separated centuries from each other, an assertion as to their relationship needs specifics in terms of dates and material connection, or it is plainly wrong.

These are the funerary ritual features from Złota (later specialized in Corded Ware), as described by Włodarczak (2017):

  • Single burial graves; along with the habit of interring the deceased in multiple burial graves, but emphasizing their individual character by careful deposition of the body and personal nature of the grave goods.
  • Grave goods with materials and stylistiscs belonging to an older system (e.g. amber products); and others correlated to the ‘new world’ of the CWC, such as flint products made of the raw materials tipical of Lesser Poland’s CWC, copper ornaments, stone shaft-hole axes, bone and shell ornaments, and characteristic forms of vessels like beakers and amphoras.
  • Military goods, which would become prevalent in later periods, are present in a moderate number, compatible with their lesser importance.
  • There are also cases of the characteristic catacomb (“niche”) graves – with an entrance pit, a more extensive niche, and a narrow corridor leading to a vault – , as well as some individual cases of application of ochre and deformation of skulls.

It seems that the Złota funerary tradition was also “transitional”, like corded ware vessels, into the classical Corded Ware ideology. But “transitional” from what exactly? Yamna? Probably not.

The Lublin-Volhynia culture

One needs not look for a too distant culture to find similarities. Włodarczak (2017) points to CWC in south-eastern Poland and Kuyavia showing, by the time of the Yamna expansion, a funeral rite and features of the material culture without straightforward analogies in the world of north Pontic communities, and thus suggests that the “A-horizon” is a local phenomenon of central European origin.

This assertion is interesting, in so far as most Corded Ware samples investigated to date seem to come precisely from an East-Central territory near the Ukraine forest steppe, with a cluster already established by the end of the 5th millennium:

The following text is from Stanisław Wilk (2018), about the Lublin-Volhynian (and related) cemeteries at Wyciąże and Książnice:

lublin-volhynia-culture
A reach of the Wyciąże-Złotniki group and Lublin-Volhynian culture in the south-eastern Poland and western Ukraine: 1. Area of the Wyciąże-Złotniki group; 2. Area of the Lublin-Volhynian culture. A.

Wilk based on Zakościelna 2006 and Nowak 2014, on a background downloaded from https://maps-for-free.com/).

Regardless of the differences between the two necropolises (such as the number of burials, the area which has been explored, the orientation and layout of burials), it seems that they have several key elements in common:

  • concentration of graves in separate cemeteries;
  • differentiation of burials with regard to sex (the principle of the ‘left ̶ right’ side, different burial goods for males and females);
  • stratification of graves with regard to the richness of their inventories (this mainly applied to copper artefacts);
  • occurrence of indicators of the richest male burials (a copper dagger in Wyciąże, a copper battle axe, a small axe and a chisel in Książnice);
  • allocation of a separate area for elite burials (the eastern burial area in Książnice, and the southeastern and north-central part of the necropolis in Wyciąże), as well as one for egalitarian burials (the western area in Książnice, and the south-central and western part of the cemetery in Wyciąże).

Plan of the Lublin-Volhynian culture cemetery at site 2 in Książnice: 1. female graves; 2. man graves; 3. copper traces; 4. cenothap; 5. cremation grave; 6. partial grave; 7. estimated area of the L-VC cemetery; 8. estimated area of an elite and poor burial fields; 9. area of burials containing copper artefacts (drawing by S. Wilk).

The above-mentioned characteristics prove that the patterns of social and religious behaviours from areas lying beyond the Carpathian Mountains exerted a strong influence on the two societies living in Lesser Poland.

Anna Zakościelna, while describing the similarities between the burial ritual of the late Polgár groups and cultures from areas on the Tisza river and the Lublin-Volhynia culture, claimed that:

a characteristic feature of the burial ritual of both cultures was practicing various group norms, which required different treatment of the deceased depending on their sex, age and social rank. As in the Lublin-Volhynia culture, the opposition ‘male – female’ can the most clearly be observed ̶ particularly, in the consistent positioning of males on the right, and females, on the left side. And, there is much indication that this ritual norm divided the deceased from early childhood (Sofaer Derevensky 1997: 877, Tab. 1; Lichter 2001: 276- 280, 322-323) (Zakościelna 2010: 227-228).

It seems that these observations can also be extended to the Wyciąże-Złotniki group.

Another question is whether the evidence of the influences of the copper civilization observed in both cemeteries emerged as a result of the literal copying of patterns from the south, or whether the latter were only a source of inspiration for local solutions.

Looking at this problem form the perspective of the details of burial ritual, between the Carpathian Basin and Lesser Poland, we can observe clear differences, among others, in the size of cemeteries and orientation of burials. While, in the Carpathian Basin there were large necropolises, consisting of several dozen burials located in rows, with the dominant orientation along the SE-NW and E-W axis (Lichter 2001: Abb. 123, 143; Kadrow 2008: 87); in Lesser Poland there were small cemeteries of several to a dozen or so burials, mostly oriented along the S-N axis (in the Lublin-Volhynia culture; Zakościelna 2010: 66), as well as S-E and NE-SW (in the Wyciąże-Złotniki group; Kaczanowska 2009: 77). Similarly, there are differences in the details of the burial goods. North of the Carpathians, there is a much smaller frequency of copper artefacts, particularly in the group of prestigious, heavy items (battle axes, axes and daggers), as well as a complete lack of objects made of gold. Want is more, the pottery found in the graves has a distinct local character, only supplemented by imitating or imports from areas beyond the Carpathians (Zakościelna 2006: 85; Nowak 2014: 273; a different opinion Kozłowski 2006: 57). Therefore, the suggestion made by Nowak seems right ̶ namely, that these influences were not caused by migrations of groups of the population living on the Tisza river to Lesser Poland, but were rather due to processes of selective cultural transmission (Nowak 2014: 273).

Therefore, the sharing of a similar funerary rite (as happened later between Lublin-Volhynia and Złota), although it shows a strong cultural connection with autochthonous cultures, is obviously not the same as sharing ancestors; and even if it were so, they would not need to be paternal ancestors. But it shows that important Corded Ware cultural traits are local developments, and it disconnects thus still more supposed CWC ‘steppe traits’ from steppe cultures, and connects them with the first steppe-related cultural wave that reached central Europe in the 5th millennium BC.

Prehistoric Pontic—Caspian links

How would a Lublin-Volhynia culture be related to the North Pontic area ca. 4500-3000 BC? We can enjoy the map series of Baltic—Pontic migrations by Viktor Klochko (2009), and make a wild guess:

baltic-pontic-routes
Pontic—Baltic routes of migrations during the Eneolithic. Top left: Linear Pottery expansion. Top right: Funnel Beaker expansion. Bottom left: late Trypillia expansion. Bottom right: GAC expansion.

And then read the account of Sławomir Kadrow, in Exchange of People, Ideas and Things between Cucuteni-Trypillian Complex and Areas of South-Eastern Poland (2016):

In the second half of the 5th millennium BC (horizon 1), communities of the Tripolye culture, phases BI-BII, had contacts with the population of the late (IIa) phase of the Malice culture. The areas settled by both cultural complexes were located at a great distance from each other. The communities of the Tripolye culture adopted selected features of Malice ceramic production (fig 2). This seems to have resulted from marital exchange: on a moderate scale, Tripolye men sought out their wives in the area of the Malice culture and, according to patrilocal marriage customs, the women then moved to the Tripolye settlements, sporadically transferring ready-made ceramic products, so-called imports, to the Tripolye culture. Thus, the wives were responsible for the considerably more numerous imitations of the Malice ceramics and the long-lasting, though selective, traditions of Malice pottery passed down in their new environment. The patrilocal marriage customs involving the Malice women and the Tripolye men (never the other way round), and the fact that pottery was women’s domain, led to the unidirectional transfer of vessels, technology and norms of ceramic production from the Malice culture to the Tripolye culture.

The turn of the 5th and the 4th millennia and the early 4th millennium BC (horizon 2) witnessed the deepening interaction between the populations of the youngest (IIb) phase of the Malice culture and the classic (II) phase of the Lublin-Volhynia culture on the one hand and the communities of phase BII of the Tripolye culture on the other. The Danube and the Tripolye settlement complexes came into contact on the upper Dniester and between the Styr and the Horyn rivers in Volhynia. This helped to continue the previous forms of marital exchange, which resulted in further popularisation of the ceramics and the traditions of ceramic production typical of the Danube cultures, i.e. the Malice and the Lublin-Volhynia cultures, and also the Polgár culture, in the areas settled by the Tripolye cultural complex.

As the civilizational norms of the Eneolithic (Copper) Age became widespread in that period, the forms of interaction described above acquired new elements. The deepening internal diversification of the early Eneolithic communities of the Lublin-Volhynia culture led to a growing demand for prestige objects, which was met with import or imitation of copper artefacts, mainly those from the Carpathian Basin, and with flint tools produced from long blades. That type of flint production depended largely on new technologies derived from the Tripolye culture, as proven by such borrowings as troughlike retouch or the very idea and technology for the production of long flint blades in the Lublin-Volhynia culture. It seems that the influx of Tripolye settlers into flintbearing areas in Volhynia and on the upper Dniester, adjacent to the settlement centres of the late phase of the Malice culture and the Lublin-Volhynia culture, created sufficient conditions for the expanding influence of the Tripolye flint working on the communities of the Eneolithic Lublin-Volhynia culture.

In the mid-4th millennium BC (horizon 3), those forms of interaction between the Danube communities (the late phase of the Lublin-Volhynian culture) and the Tripolye communities (phase CI)were continued. Elements of the Danube pottery still grew in popularity in the Tripolye population, while selected features of the Tripolye flint working were adopted by the Lublin-Volhynia culture.

In that period, the population of the Funnel Beaker culture of the pre-classic and early classic phases (the beginnings of Gródek 1 and Bronocice III), until then absent from those areas, quite quickly drove out and replaced the Danube population in western Volhynia and the upper Dniester basin. This caused significant changes in the forms and intensity of the intercultural interaction, which became fully apparent already in the 2nd half of the 4th millennium BC.

In the following period (horizon 4), the population of the classic phase of the Funnel Beaker culture (Gródek 1, Bronocice III) settled more and more intensively the upper Dniester basin, up to the Hnyla Lypa river, and western Volhynia, up to the Styr river. East of those rivers, the Funnel Beaker settlers created considerable areas where they mixed with settlers from early phase CII of the Tripolye culture. Their coexistence, lasting there for many generations, resulted in deepening the interactions between members of both cultural complexes and in developing entirely new forms of relationships.

(…)

The intensifying interaction between the communities of the Funnel Beaker culture and the Tripolye culture, early phase CII, in the 2nd half of the 4th millennium BC (horizon 4) was an introduction to, and perhaps a condition for, even more frequent contacts in the next period, the first centuries of the 3rd millennium BC (horizon 5). In that case, the interaction was mainly triggered by multidirectional migrations of larger human groups, involving a significant part of the population of all cultures from the areas discussed here. The Tripolye communities of younger phase CII settled Volhynia, its eastern areas in particular, from the south and the south-east, while groups representing the younger phases of the Funnel Beaker culture (Gródek 2), often with Baden features (Bronocice IV and V), moved increasingly into the western part of that region. The Yamna communities expanded along the lower and central Danube to the west, whereas the populations of the late phase of the Baden culture took the opposite direction, reaching as far as Kiev in the northeast, and contributed to the cultural character of the Sofievka group.

The communities of the Globular Amphora culture migrated from the north-west, from eastern Poland, towards the Danube Delta and as far as the Dnieper in the east, while the multicultural population from the areas around the mouth of the Danube moved in the opposite direction, carrying with them cultural elements from Thrace, or even from Anatolia. Some of them returned to the starting point (to south-eastern Poland), bringing with them a new form of pottery, so-called Thuringian amphora, borrowed from the late Trypillian Usatovo group. This resulted in origins of the Złota culture, a cultural phenomenon that gave beginnings to the oldest Corded Ware culture. Inventories of both cultures contained the already mentioned Thuringian amphorae.

Here is a more recent assessment (2017) of the latest radiocarbon analyses of the available settlements of cultures in the area, published by Marek Novak (announced in a previous post), which gives the following data on Wyciąże-Złotniki, Lublin-Volhynia, and Wyciąże/Niedźwiedź:

This scheme unambiguously suggests both the overlapping and contiguous nature of cultural development in western Lesser Poland within the Middle Neolithic. The basic elements of this development are: 1) the Wyciąże-Złotniki group and the Lublin-Volhynian culture, until c. 3650–3550 cal BC; 2) the Funnel Beaker culture proper, which appeared c. 3750–3700c al BC, and existed until c. 3300–3250 cal BC, perhaps accompanied by the Wyciąże/Niedźwiedź materials from c. 3650–3550 cal BC; and 3) the Baden culture and the Funnel Beaker/Baden assemblages from 3100 and 3300–3100 cal BC, respectively, until 2850–2750 and 2850 cal BC, with – possibly – later Funnel Beaker culture and Wyciąże/ Niedźwiedź materials, existing until c. 3100 cal BC.

The final scheme shows that the Lublin-Volhynian culture could have coincided with the Wyciąże-Złotniki group. In view of the territorial relationship between them, relations from the point of view of material culture, primarily in the field of pottery, become particularly interesting. It is relatively easy to see clear similarities between these units. However, the most evident similarities apply only to some categories of ceramics, including, for example, vessels with Scheibenhenkel handles. What is more, in the period between the late 38th and early 36th centuries BC, the early Funnel Beaker and possibly early Baden influences are superimposed on this Lublin-Volhynian/Wyciąże-Złotniki ‘mix’.

[About Corded Ware: The] development of this unit in central Europe, including western Lesser Poland, [] usually point to c. 2800 cal BC (Włodarczak 2006a). (…) the calibration curve makes it possible to alternatively refer several dates earlier than c. 3100 to c. 2850–2800 cal BC.

Conclusion

There is no direct archaeological link of Lublin-Volhynia-related groups with Corded Ware, beyond the fact that they shared homeland and Central European (‘steppe-related’) traits, as found in the Złota culture. But there is no direct link of Yamna with Corded Ware, either, whether in terms of culture or population.

So, given the evident link of R1a-Z93 and steppe ancestry with the forest steppe ca. 4000 BC, the surrounding North Pontic areas in contact along the Dniester, Dnieper, Bug, and Prut are the best candidates for the appearance of R1a-Z283: steppe cultures to the south and south-west; sub-Neolithic (Comb Ware) groups to the north in the forest zone; and Eneolithic groups to the west and north-west.

Seeing how ‘ancestral components’ and PCA cluster can change within a few generations, the question of the spread of R1a-Z645 subclades is still not settled by a single sample in Alexandria. However, based on the explosive expansions we are seeing from small territories, it would not be surprising to find R1a-Z93 and R1a-Z283 side by side in the same small area within the forest steppe.

NOTE. An archaeological link may not mean anything relevant in genetics, especially – as in this case – when no clear migration event has been traced to date. We have seen exactly that with Kristiansen’s proposal of a long-term genetic admixture of Yamna with Trypillia and GAC to form Corded Ware, which didn’t happen. The cultural and ideological connection of CWC peoples with Lublin-Volhynian tradition may be similar to the already known connection with GAC, and not mean anything in genetic finds; at least in terms of Y-DNA haplogroup.

We believed in the 2000s that Corded Ware represented the expansion of Late Proto-Indo-European, because the modern map of haplogroup R1a showed a distribution similar to how we thought the European and Indo-Iranian languages could have expanded. This has been proven wrong, and that’s what ancient DNA is for; not to confirm the own ideas or models, or to support modern ideologies.

It is impossible to know if R1a-Z645 comes from the steppe, forest steppe, or forest zone, until more samples are published. I don’t think there will be any big surprise, no matter where it is eventually found. By now, adding linguistic reconstruction to archaeological traits, and to the genetic data from Yamna and Corded Ware settlers, the only clear pattern is that patrilineal clans expanded, during the Final Eneolithic / Chalcolithic:

  • Late Proto-Indo-European with Yamna and R1b-L23 subclades, given the known genomic data from Khvalynsk, Yamna, Afanasevo, Bell Beaker, Catacomb, and Poltavka—Sintashta/Potapovka.
  • Uralic with Corded Ware and R1a-Z645 subclades, given the known genomic data from Fennoscandia and the Forest Zone.

Everything else is just wishful thinking at this moment.

Abstract (emphasis mine):

Along the western Norwegian coast, in the northwestern region of the Nordic Late Neolithic and Bronze Age (2350–500 BCE) there is cultural homogeneity but variable expressions of political hierarchy. Although new ideological institutions, technology (e.g., metallurgy and boat building), intensified agro‑pastoral farming, and maritime travel were introduced throughout the region as of 2350 BCE, concentrations of expressions of Bronze Age elites are intermittently found along the coast. Four regions—Lista, Jæren, Karmøy, and Sunnmøre—are examined in an exploration of the establishment and early role of maritime practices in this Nordic region. It is argued that the expressions of power and material wealth concentrated in these four regions is based on the control of bottlenecks, channels, portages, and harbors along important maritime routes of travel. As such, this article is a study of prehistoric travel, sources of power, and maritime landscapes in the Late Neolithic and Early Bronze Age of Norway.

Interesting excerpts:

(…)The [Corded Ware culture (CWC)] in Norway (or Battle Axe Culture, 2750–2400/2350 BCE) is primarily represented in Eastern Norway, with a patchy settlement pattern along the Oslo fjord’s coast through the inland valleys to Trøndelag in Central Norway (Hinsch 1956). The CWC represents an enigmatic period in Norwegian prehistory (Hinsch 1956; Østmo 1988:227–231; Prescott and Walderhaug 1995; Shetelig 1936); however the data at the moment suggests the following patterns:

  • Migration: The CWC was the result of a small‑scale immigration, but did not trigger substantial change.
  • Eastern and limited impact: The CWC was primarily located in small settlement patches in eastern Norway.
  • Terrestrial: In terms of maritime practices, the CWC does not represent a significant break from older traditions, though it seems to have a more pronounced terrestrial bearing. It is conceivable that pastures and hunting grounds were a more important political‑economic resource than waterways.

The mid‑third millennium in Norway, around 2400 BCE, represents a significant reorientation. Bell Beaker Culture (BBC) settlements in western Denmark and Norway archaeologically mark the instigation of the Nordic LN, though much of the historical process leading from the Bell Beaker to the Late Neolithic, 2500 to 2350 BCE, remains unclear (Prescott 2012; Prescott and Melheim 2009; Prieto‑Martinez 2008:116; Sarauw 2007:66; Vandkilde 2001, 2005). Still, the outcome is the establishment of the Nordic region of interaction in the Baltic, Northern Germany, Sweden, Denmark, and Norway. The distribution of artifact materials such as Bell Beakers and flint daggers attests to the far‑flung network of regular exchange and communication. This general region of interaction was reproduced through the Late Neolithic and Bronze Age.

The transition from the preceding Neolithic period hunter‑gatherer societies was rapid and represents a dramatic termination of hunter‑gatherer traditions. It has been argued that the transformation is tied to initial migrations of people to the western coast of Norway from BBC areas, possibly from northern Jutland (Prescott 2011; Prescott and Walderhaug 1995:273). Bifacial tanged‑and‑barbed points, often referred to as “Bell Beaker points,” probably represent an early, short phase of the BBC‑transition around 2400 BCE. In Norway these points have a predominantly western and coastal distribution (Østmo 2012:64), underscoring the maritime nature of the initial BBC‑expansion.

(…) In response to the question about what attracted people from Bell Beaker groups to western Norway, responses have hypothesized hunting products, political power, pastures, and metals. Particularly the latter has been emphasized by Lene Melheim (2012, 2015:37ff).

A recent study by Melheim and Prescott (2016) integrated maritime exploration with metal prospecting to explain initial excursions of BBC‑people along the western coast and into the fjords. Building on the archaeological concept of traveling metal prospectors as an element in the expansion of the Bell Beaker phenomenon, in combination with anthropological perspectives on prospecting, the article explores how prospecting for metal would have adjusted to the landscapes of western Scandinavia. Generally speaking, prospecting seldom leads to successful metal production, and it is difficult to study archaeologically. However, it will often create links between the prospectors’ society and indigenous groups, opening new territories, and have a significant transformative impact—on both the external and indigenous actors and societies.

While the text echoes the traditional idea that Corded Ware spread Indo-European languages, Prescott (since Prescott and Walderhaug 1995) is a supporter of the formation of a Nordic community and a Nordic (i.e. Pre-Germanic) language with the arrival of Bell Beakers.

An identification of the Corded Ware language as of a previous Proto-Indo-European stage is possible, as I have previously said (although my preference is Uralic-related languages).

This CWC language would thus still form the common substrate to both Germanic and Balto-Slavic, both being North-West Indo-European dialects, which spread with Bell Beakers over previous Corded Ware territory.

NOTE. This pre-LPIE nature could be in turn related to Kortlandt’s controversial proposal of an ealier PIE dative *-mus shared by both branches. However, that would paradoxically be against Kortlandt’s own assumption that the substrate was in fact of a non-Indo-European nature
