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


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.

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).

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.

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.

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 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 Europe – 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.

Middle Bronze Age cultures of Eastern Europe.

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]

Baltic Finns in the Bronze Age, of hg. R1a-Z283 and Corded Ware ancestry


Open access The Arrival of Siberian Ancestry Connecting the Eastern Baltic to Uralic Speakers further East, by Saag et al. Current Biology (2019).

Interesting excerpts:

In this study, we present new genomic data from Estonian Late Bronze Age stone-cist graves (1200–400 BC) (EstBA) and Pre-Roman Iron Age tarand cemeteries (800/500 BC–50 AD) (EstIA). The cultural background of stone-cist graves indicates strong connections both to the west and the east [20, 21]. The Iron Age (IA) tarands have been proposed to mirror “houses of the dead” found among Uralic peoples of the Volga-Kama region [22].

(…) The 33 individuals included 15 from EstBA, 6 from EstIA, 5 from Pre-Roman to Roman Iron Age Ingria (500 BC–450 AD) (IngIA), and 7 from Middle Age Estonia (1200–1600 AD) (EstMA) and yielded endogenous DNA ∼4%–88%, average genomic coverages ∼0.017–0.734×, and contamination estimates <4% (Table S1). We analyzed the data in the context of modern and other ancient individuals, including from Neolithic Estonia [13].

Archaeological Information, Genetic Sex, mtDNA and Y Chromosome Haplogroups, and Average Coverage of the Individuals of This Study. Modified from the paper to mark distinct Y-DNA haplogroups in the LBA and IA.

We identified chrY hgs for 30 male individuals (Tables 1 and S2; STAR Methods). All 16 successfully haplogrouped EstBA males belonged to hg R1a, showing no change from the CWC period, when this was also the only chrY lineage detected in the Eastern Baltic [11, 13, 30, 31]. Three EstIA and two IngIA individuals also belonged to hg R1a, but three EstIA males belonged to hg N3a, the earliest so far observed in the Eastern Baltic. Three EstMA individuals belonged to hg N3a, two to hg R1a, and one to hg J2b. ChrY lineages found in the Baltic Sea region before the CWC belong to hgs I, R1b, R1a5, and Q [10, 11, 12, 13, 17, 32]. Thus, it appears that these lineages were substantially replaced in the Eastern Baltic by hg R1a [10, 11, 12, 13], most likely through steppe migrations from the east [30, 31]. (…) Our results enable us to conclude that, although the expansion time for R1a1 and N3a3′5 in Eastern Europe is similar [25], hg N3a likely reached Estonia or at least became comparably frequent to modern Estonia [1] only during the BA-IA transition.

A clear shift toward West Eurasian hunter-gatherers is visible between European LN and BA (including Baltic CWC) and EstBA individuals, the latter clustering together with Latvian and Lithuanian BA individuals [11]. EstIA, IngIA, and EstMA individuals project between BA individuals and modern Estonians, partially overlapping with both.

(…) EstBA individuals are clearly distinguishable from Estonian CWC individuals as the former have more of the blue component most frequent in WHGs and less of the brown and yellow components maximized in Caucasus hunter-gatherers and modern Khanty, respectively. The individuals of EstBA, EstIA, IngIA, EstMA, and modern Estonia are quite similar to each other on average, indicating that the relatively high proportion of WHG ancestry in modern Eastern Baltic populations compared to other present-day Europeans [15] traces back to the BA.

Detail of the PCA, modified from the paper to label populations. Estonian Bronze Age and Iron Age samples cluster close to Early Corded Ware from the Baltic.. Principal-component analysis results of modern West Eurasians with ancient individuals projected onto the first two components (PC1 and PC2). BA, Bronze Age; EF, early farmers; HG, hunter-gatherers; IA, Iron Age; IMA, Iron/Middle Ages; LN, Late Neolithic; LNBA, Late Neolithic/Bronze Age; MA, Middle Ages

When comparing Estonian CWC and EstBA using autosomal outgroup f3 and Patterson’s D statistics (Table S3), the latter is more similar to other Baltic BA populations, to Baltic IA and Middle Age (MA) populations, and also to populations similar to WHGs and Scandinavian hunter-gatherers (SHGs), but not to Estonian CCC (Figures 2A and S2A; Data S1). The increase in WHG or SHG ancestry could be connected to western influences seen in material culture [20, 21] and facilitated by a decline in local population after the CCC-CWC period [20]. A slight trend of bigger similarity of Estonian CWC to forest or steppe zone populations and of EstBA to European early farmer populations can also be seen.

(…) When comparing to modern populations, Estonian CWC is slightly more similar to Caucasus individuals but EstBA to Baltic populations and Finnic speakers (Figure 2B; Data S1). Outgroup f3 and D statistics do not reveal apparent differences when comparing EstBA to EstIA, EstIA to IngIA, and EstIA to EstMA (Data S1).

qpAdm results. Error bars indicate one SE. Central MN, Central European Middle Neolithic; EstBA, Estonian Bronze Age; EstIA, Estonian Iron Age; IngIA, Ingrian Iron Age; EstMA, Estonian Middle Ages; WHG, western hunter-gatherers.

These results highlight how uniparental and autosomal data can lead to different demographic inferences—the genetic change between CWC and BA not seen in uniparental lineages is clear in autosomal data and the appearance of chrY hg N in the IA is not matched by a clear shift in autosomal profiles.

EstBA individuals have no Nganasan-related ancestry and EstIA, IngIA, and EstMA individuals on average have 2% or 4% (Figure 3; Data S1). The differentiation remains when using BA or IA Fennoscandian populations [26] instead of Nganasans (Data S1). Notably, the proportion of Nganasan-related ancestry varies between 0% and 12% among sampled EstIA, IngIA, and EstMA individuals (Data S1), which may suggest its relatively recent admixture into the target population. Moreover, two individuals from Kunda (0LS10 and V10) have the highest proportions of Nganasan ancestry among EstIA (6% and 8%), one of them has chrY hg N3a, and isotopic analysis suggests neither individual being born in Kunda [34].

About these two males from Tarand-graves, ‘foreign’ to Kunda:

0LS10: Male from tarand III (burial 9; TÜ 1325: L777), age 17–25 years [34]. He had a fragment of a sheep/goat bone and ceramics as grave goods. This burial has two radiocarbon dates: 2430 ± 35 BP (Poz-10801; 760–400 cal BC) and 2530 ± 41 BP (UBA-26114; 800–530 cal BC) [34]. According to the isotopic analysis, the person was not born in the vicinity of Kunda; his place of birth is still unknown (but south-western Finland and Sweden are excluded) [34]. Sampled tooth r P1.

V10: Male from tarand XI (burial 24; TÜ 1325: L1925), age 25–35 years [34], date 2484 ± 40 BP (UBA-26115; 790–430 cal BC) [34]. He had a few potsherds near the skull. Likewise, this person was not locally born [34]. Sampled tooth l P1.

Autosomal Analyses’ Results for Gyvakarai1 as the closest available Corded Ware source for Balto-Finnic populations.

The paper shows thus:

  • Major continuity of ancestry from Corded Ware to modern Estonians, with only slight changes in different periods. In fact, one of the best fits for the Late Bronze Age ancestry is Gyvakarai1, one of the Corded Ware “outliers” described as “closer to Yamna”, which I already said may be closer to Sredni Stog/EHG populations instead. Another interesting take is that the change from Bronze Age to Iron Age corresponds to an increase in Baltic Corded Ware-related ancestry, rather than being driven by Siberian ancestry.

  • A Volosovo-related migration of hg. N1c with Netted Ware into the area seems to be discarded, based on the full replacement of paternal lines and continuity of R1a-Z283. It is only during the Tarand-grave period when a system of chiefdoms (spread from Ananyino/Akozino) brings haplogroup N1c to the Gulf of Finland. During the Iron Age, the proportion of paternal lineages is still clearly in favour of R1a (50% in the coast, 100% in Ostrobothnia), which indicates a gradual replacement led by elites, likely because of the incorporation of Akozino warrior-traders spreading all over the Baltic, bringing the described shared Mordvinic traits in Fennic.

Blue arrows represent eventual expansions of Uralic peoples to the north. Modified image from Vasilyev (2002).
  • The arrival of Akozino warrior-traders (bringing N1c and R1a lineages) was probably linked to this minimal “Nganasan-like” ancestry of some samples in the transition to the Iron Age. This arrival is supported by samples 0LS10 (the earliest hg. N1c) and V10 (of hg. R1a), both dated to ca. 800-400 BC, with V10 showing the highest “Nganasan-like” ancestry with 4.8%, both of them neighbouring samples showing 0%. This variable admixture among local and foreign paternal lineages might support the described social system of family alliances with intermarriages. In fact, a medieval sample, 0LS03_1 (hg. R1a) also shows a recent “Nganasan-like” ancestry, which probably points to the integration of different Arctic-related ancestry components among Modern Estonians, in this case related to Finnish expansions and thus integration of Levänluhta-related ancestry, as per the supplementary data.
  • NOTE. Such minimal proportions of “Nganasan-like” ancestry evidence the process of admixture of Volga Finns in Akozino territory through their close interactions with Permians of Ananyino, who in turn acquired this Palaeo-Arctic admixture most likely during the expansion of the linguistic community to hunter-gatherer territories, to the north of the Cis-Urals. This process of stepped infiltration and expansion without language change is not dissimilar to the one seen among Indo-Iranians and Balto-Slavs of hg. R1b, or Vasconic speakers of hg. I2a, although in the case of Baltic Finns of hg. R1a the process of infiltration and expansion of hg. N1c is much less dramatic, with no radical replacement anywhere before the huge bottlenecks observable in Finns.

  • The expansion of haplogroup N1c among Finnic populations, as we are going to see in samples from the Middle Ages such as Luistari, is the consequence of late founder effects after huge bottlenecks expected based on the analysis of modern populations. The expansion of N1c-VL29 is different in origin from that of N1c-Z1936 among Samic (later integrated into Finnish populations), most likely from the east and originally associated with Lovozero Ware.

In spite of all this, the conclusion of the paper is (surprise!) that Siberian ancestry and hg. N heralded the arrival of Finnic to the Gulf of Finland in the Iron Age… However, this conclusion is supposedly* supported, not by their previous papers, but by a recent phylogenetic study by Honkola et al. (2013), which doesn’t actually argue for such a late ‘arrival’: it argues for the split of Balto-Finnic around 1500 BC.

NOTE. I say ‘supposedly’ because Kristiina Tambets, for example, has been following the link of Uralic with haplogroup N since the 2000s, so this is not some conclusion they just happened to misread from some random paper they Googled. In those initial assessments, she argued that the “ancient homeland” of the Tat C mutation suggested that Finno-Ugrians were in Fennoscandia before Indo-Europeans. Apparently, since haplogroup N appears later and from the east, it is now more important to follow this haplogroup than what is established in archaeology and linguistics.

Even in the referred paper, this split is considered an in situ development, since the phylogenetic study takes the information – among others – 1) from Parpola and Carpelan, who consider Netted Ware, a culture derived from Fatyanovo/Abashevo and Volosovo, as the culprit of the Finno-Ugric expansion; and 2) from Kallio (2006), who clearly states that Proto-Balto-Finnic (like Proto-Finno-Samic) was spoken around the Gulf of Finland during the Bronze Age. Both of them set the terminus ante quem of the language presence in the Baltic ca. 1900 BC.

Anyways, as a consequence of geneticists keeping these untenable pre-ancient DNA haplogroup-based arguments today, I expect to see this “Finnic” language expansion also described for the Western Baltic, Scandinavia or northern Europe, when this same proportion of hg. N1c and “Nganasan” ancestry is observed in Iron Age samples around the Baltic Sea. The nativist trends that this domination of “Finns” all over Northern Europe 2,500 years ago will create will be even more fun to read than the current ones…

EDIT (10 May 2019) How I see the reaction of many to ancient DNA, in keeping their old theories:


Yekaterinovsky Cape, a link between the Samara culture and early Khvalynsk


We already had conflicting information about the elite individual from the Yekaterinovsky Cape and the materials of his grave, which seemed quite old:

For the burial of 45 in the laboratory of the University of Pennsylvania, a 14C date was obtained: PSUAMS-2880 (Sample ID 16068)> 30 kDa gelatin Russia. 12, Ekaterinovka Grave 45 14C age (BP) 6325 ± 25 δ 13C (‰) –23.6 δ15 N (‰) 14.5. The results of dating suggest chronological proximity with typologically close materials from Yasinovatsky and Nikolsky burial grounds (Telegini et al. 2001: 126). The date obtained also precedes the existing dates for the Khvalynsk culture (Morgunova 2009: 14–15), which, given the dominance of Mariupol traits of the burial rite and inventory, confirms its validity. However, the date obtained for human bones does not exclude the possibility of a “reservoir effect” when the age can increase three or more centuries (Shishlin et al. 2006: 135–140).

Now the same date is being confirmed by the latest study published on the site, by Korolev, Kochkina, and Stachenkov (2019) and it seems it is really going to be old. Abstract (in part the official one, in part newly translated for clarity):

For the first time, pottery of the Early Eneolithic burial ground Ekaterinovsky Cape is published. Ceramics were predominantly located on the sacrificial sites in the form of compact clusters of fragments. As a rule, such clusters were located above the burials, sometimes over the burials, some were sprinkled with ocher. The authors have identified more than 70 vessels, some of which have been partially reconstructed. Ceramic was made with inclusion of the crushed shell into molding mass. The rims of vessels had the thickened «collar»; the bottoms had a rounded shape. The ornament was located on the rims and the upper part of the potteries. Fully decorated vessels are rare. The vessels are ornamented with prints of comb and rope stamps, with small pits. A particularity of ceramics ornamentation is presented by the imprints of soft stamps (leather?) or traces of leather form for the making of vessels. The ornamentation, made up of «walking comb» and incised lines, was used rarely as well as the belts of pits made decoration under «collar» of a rim. Some features of the ceramics decoration under study relate it with ceramics of the Khvalynsk culture. The ceramics of Ekaterinovsky Cape burial ground is attributed by the authors to the Samara culture. The ceramic complex under study has proximity to the ceramics from Syezzhe burial ground and the ceramics of the second phase of Samara culture. The chronological position is determined by the authors as a later period than the ceramics from the Syezzhe burial ground, and earlier than the chronological position of ceramics of the Ivanovka stage of the Samara culture and the Khvalynsk culture.

Ceramics from Ekaterinovsky Cape burial ground. 1–2, 4–5, 7–11 – ceramics from aggregations; 3, 6 – ceramics from the cultural layer.

More specifically:

Based on ceramic fragments from a large vessel from a cluster of sq.m. 14, the date received was: SPb-2251–5673 ± 120 BP. The second date was obtained in fragments from the aggregation [see picture above] from the cluster of sq.m. 45–46: SPb-2252–6372 ± 100 BP. The difference in dating indicates that the process of determining the chronology of the burial ground is far from complete, although we note that the earlier date almost coincided with the date obtained from the human bone from individual 45 (Korolev, Kochkina, Stashenkov, 2018, p. 300).

Therefore, the ceramics of the burial ground Ekaterinovsky Cape possess an originality that determines the chronological position of the burial ground between the earliest materials of the burial type in Syezzhe and the Khvalynsk culture. Techno-typological features of dishes make it possible to attribute it to the Samara culture at the stage preceding the appearance of Ivanovska-Khvalynsk ceramics.

It seems that this site showed cultural influences from the upstream region near the Kama-Vyatka interfluve, too, according to Korolev, Kochkina, Stashenkov, and Khokhlov (2018):

In 2017, excavation of burial ground Ekaterinovsky Cape were continued, located in the area of the confl uence of the Bezenchuk River in the Volga River. During the new excavations, 14 burials were studied. The skeleton of the buried were in a position elongated on the back, less often – crooked on the back with knees bent at the knees. In one burial (No. 90), a special position of the skeleton was recorded. In the burial number 90 in the anatomical order, parts of the male skeleton. This gave grounds for the reconstruction of his original position in a semi-sitting position with the support of elbows on the bottom of the pit. Noteworthy inventory: on the pelvic bones on the left lay a bone spoon, near the right humerus, the pommel of a cruciform club was found. A conclusion is made about the high social status of the buried. The results of the analysis of the burial allow us to outline the closest circle of analogies in the materials of Khvalynsky I and Murzikhinsky burial grounds.

Important sites mentioned in both papers and in this text:

To sum up, it seems that the relative dates we have used until now have to be corrected: older Khvalynsk I Khvalynsk II individuals, supposedly dated ca. 5200-4000 BC (most likely after 4700 BC), and younger Yekaterinovsky individuals, supposedly of the fourth quarter of the 5th millennium (ca. 4250-4000 BC), are possibly to be considered, in fact, roughly reversed, if not chronologically, at least culturally speaking.

Interestingly, this gives a new perspective to the presence of a rare fish- or reptile-headed pommel-scepter, which would be natural in a variable period of expansion of the horse and horse-related symbolism, a cultural trait rooted in the Samara culture attested in Syezzhe before the unification of the symbol of power under the ubiquitous Khvalynsk-Suvorovo horse-headed scepters and related materials.

The Khvalynsk chieftain

If the reported lineages from Yekaterinovsky Cape are within the R1b-P297 tree, but without further clades, as Yleaf comparisons may suggest, there is not much change to what we have, and R1b-M269 could actually represent a part of the local population, but also incomers from the south (e.g. the north Caspian steppe hunter-gatherers like Kairshak), the east (with hunter-gatherer pottery), or the west near the Don River (in contact with Mariupol-related cultures, as the authors inferred initially from material culture).

Just like R1a-M417 became incorporated into the Sredni Stog groups after the Novodanilovka-Suvorovo expansion, probably as incoming hunter-gatherer pottery groups from the north admixing with peoples of “Steppe ancestry”, R1b-M269 lineages might have expanded explosively only during the Repin expansion, and maybe (like R1b-L51 later) they formed just a tiny part of the clans that dominated the steppe during the Khvalynsk-Novodanilovka community.

On the other hand, the potential finding of various R1b-M269/L23 samples in Yekaterinovsky Cape (including an elite individual) would suggest now, as it was supported in the original report by Mathieson et al. (2015), that these ancient R1b lineages found in the Volga – Ural region are in fact most likely all R1b-M269 without enough coverage to obtain proper SNP calls, which would simplify the picture of Neolithic expansions (yet again). From the supplementary materials:

10122 / SVP35 (grave 12). Male (confirmed genetically), age 20-30, positioned on his back with raised knees, with 293 copper artifacts, mostly beads, amounting to 80% of the copper objects in the combined cemeteries of Khvalynsk I and II. Probably a high-status individual, his Y-chromosome haplotype, R1b1, also characterized the high-status individuals buried under kurgans in later Yamnaya graves in this region, so he could be regarded as a founder of an elite group of patrilineally related families. His MtDNA haplotype H2a1 is unique in the Samara series.

Khvalynsk cemetery and grave gifts. Grave 90 contained copper beads and rings, a harpoon, flint blades, and a bird-bone tube. Both graves (90 and 91) were partly covered by Sacrificial Deposit 4 with the bones from a horse, a sheep, and a cow. Center: grave goods from the Khvalynsk cemetery-copper rings and bracelets, polished stone mace heads, polished stone bracelet, Cardium shell ornaments, boars tusk chest ornaments, flint blades, and bifiacial projectile points. Bottom: shell-tempered pottery from the Khvalynsk cemetery. After Agapov, Vasiliev, and Pestrikova 1990; and Ryndina 1998, Figure 31. Modified from Anthony (2007).

This remarkable Khvalynsk chieftain, whose rich assemblage may correspond to the period of domination of the culture all over the Pontic-Caspian steppes, has been consistently reported as of hg. R1b-L754 in all publications, including Wang et al. (2018/2019) tentative SNP calls in the supplementary materials (obtained with Yleaf, as the infamous Narasimhan et al. 2018 samples), but has been variously reported by amateurs as within the R1b-M73, R1b-V88, or (lately) R1b-V1636 trees, which makes it unlikely that quality of the sample is allowing for a proper SNP call.

The fact that Mathieson et al. (2015) considered it a member of the R1b-M269 clans appearing later in Yamna seems on point right now, especially if samples from Yekaterinovka are all within this tree. The relevance of R1b-L23 in the expansion of Repin and Yamna is reminiscent of the influence of successful clans among Yamna offshoots, such as Bell Beakers, and among Bell Beaker offshoots during the Bronze Age all over Europe.

Taking these younger expansions as example, it seems quite likely based on cultural links that (at least part of) the main clans of Khvalynsk were of R1b-M269 lineage, stemming from a R1b-dominated Samara culture, in line with the known succeeding expansions and the expected strictly patriarcal and patrilineal society of Proto-Indo-Europeans, which would have exacerbated the usual reduction in Y-chromosome haplogroup variability that happens during population expansions, and the aversion towards foreign groups while the culture lasted.

Cultures of the Pontic-Caspian steppes and forest-steppes and surrounding areas during the Neolithic.

The finding of R1b-L23 in Yekaterinovka, associated with the Samara culture, before or during the Khvalynsk expansion, and close to the Khvalynsk site, would make this Khvalynsk chieftain most likely a member of the M269 tree (paradoxically, the only R1b-L754 branch amateurs have not yet reported for it). Similarly, the sample of a “Samara hunter-gatherer” of Lebyazhinka, of hg. R1b-P297, could also be under this tree, just like most R1b-M269 from Yamna are downstream from R1b-L23, and most reported R1b-M269 or R1b-L23 from Bell Beakers are under R1b-L151.

On the other hand, we know of the shortcomings of attributing a haplogroup expansion to the best known rulers, such as the famous lineages previously wrongly attributed to Niall of the Nine Hostages or Genghis Khan. The known presence of R1b-V1636 up to modern Greeks would be in line with an ancient steppe expansion that we know will show up during the Neolithic, although it could also be a sign of a more recent migration from the Caucasus. The presence of a sister clade of R1b-L23, R1b-PF7562, among modern Balkan populations, may also be attributed to a pre-Yamna steppe expansion.

On SNP calls

I reckon that even informal reports on SNP calls, like any other analyses, should be offered in full: not only with a personal or automatic estimation of the result, but with a detailed explanation of the good, dubious, and bad calls, alternatives to that SNP estimation, and a motivated reasoning of why one branch should be preferred over others. Downloading a sample and giving an instruction using a free software tool is never enough, as it became crystal clear recently for the hilariously biased and flawed qpAdm reports on Dutch Bell Beakers as the ‘missing link’ between Corded Ware and Bell Beakers…

Another example I can recall is the report of a R1a-Z93 subclade in the R1a-M417 sample ca. 4000 BC from Alexandria, which seems rather unlikely, seeing how this subclade must have split and expanded explosively with R1a-Z645 to the east with eastern Corded Ware groups, i.e. 1,000 years later, just like Z282 lineages expanded mainly to the north-east. But then again, as with the Khvalynsk chieftain, I have only seen indirect reports of that supposed SNP (including Y26+!), so we should just stick with its officially reported R1a-M417 lineage. This upstream haplogroup was, in fact, repeated with Yleaf’s tentative estimates in Wang et al. (2019) supplementary materials…

The combination of inexperienced, biased, or simply careless design, analyses, and reports, including SNP calls and qpAdm analyses (whether in forums or publications), however well-intentioned (or not) they might be, are hindering a proper analysis of data, adding to the difficulties we already have due to the scarcity of samples, their limited coverage, and the lack of proper context.

Some people like to repeat ad nauseam that archaeology and/or linguistics are ‘not science’ whenever they don’t fit their beliefs and myths based on haplogroup and/or ancestry. But it’s becoming harder and harder to rely on certain genetic data, too, and on their infinite changing interpretations, much more than it is to rely on linguistic and archaeological research, including data, assessments, and discussions that are open for anyone to review…if one is truly interested in them.

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


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 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.

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 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.

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.


“Steppe ancestry” step by step: Khvalynsk, Sredni Stog, Repin, Yamna, Corded Ware


Wang et al. (2018) is obviously a game changer in many aspects. I have already written about the upcoming Yamna Hungary samples, about the new Steppe_Eneolithic and Caucasus Eneolithic keystones, and about the upcoming Greece Neolithic samples with steppe ancestry.

An interesting aspect of the paper, hidden among so many relevant details, is a clearer picture of how the so-called Yamnaya or steppe ancestry evolved from Samara hunter-gatherers to Yamna nomadic pastoralists, and how this ancestry appeared among Proto-Corded Ware populations.

Image modified from Wang et al. (2018). Marked are in orange: equivalent Steppe_Maykop ADMIXTURE; 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 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.”

Please note: arrows of “ancestry movement” in the following PCAs do not necessarily represent physical population movements, or even ethnolinguistic change. To avoid misinterpretations, I have depicted arrows with Y-DNA haplogroup migrations to represent the most likely true ethnolinguistic movements. Admixture graphics shown are from Wang et al. (2018), and also (the K12) from Mathieson et al. (2018).

1. Samara to Early Khvalynsk

The so-called steppe ancestry was born during the Khvalynsk expansion through the steppes, probably through exogamy of expanding elite clans (eventually all R1b-M269 lineages) originally of Samara_HG ancestry. The nearest group to the ANE-like ghost population with which Samara hunter-gatherers admixed is represented by the Steppe_Eneolithic / Steppe_Maykop cluster (from the Northern Caucasus Piedmont).

Steppe_Eneolithic samples, of R1b1 lineages, are probably expanded Khvalynsk peoples, showing thus a proximate ancestry of an Early Eneolithic ghost population of the Northern Caucasus. Steppe_Maykop samples represent a later replacement of this Steppe_Eneolithic population – and/or a similar population with further contribution of ANE-like ancestry – in the area some 1,000 years later.


This is what Steppe_Maykop looks like, different from Steppe_Eneolithic:


NOTE. This admixture shows how different Steppe_Maykop is from Steppe_Eneolithic, but in the different supervised ADMIXTURE graphics below Maykop_Eneolithic is roughly equivalent to Eneolithic_Steppe (see orange arrow in ADMIXTURE graphic above). This is useful for a simplified analysis, but actual differences between Khvalynsk, Sredni Stog, Afanasevo, Yamna and Corded Ware are probably underestimated in the analyses below, and will become clearer in the future when more ancestral hunter-gatherer populations are added to the analysis.

2. Early Khvalynsk expansion

We have direct data of Khvalynsk-Novodanilovka-like populations thanks to Khvalynsk and Steppe_Eneolithic samples (although I’ve used the latter above to represent the ghost Caucasus population with which Samara_HG admixed).

We also have indirect data. First, there is the PCA with outliers:


Second, we have data from north Pontic Ukraine_Eneolithic samples (see next section).

Third, there is the continuity of late Repin / Afanasevo with Steppe_Eneolithic (see below).

3. Proto-Corded Ware expansion

It is unclear if R1a-M459 subclades were continuously in the steppe and resurged after the Khvalynsk expansion, or (the most likely option) they came from the forested region of the Upper Dnieper area, possibly from previous expansions there with hunter-gatherer pottery.

Supporting the latter is the millennia-long continuity of R1b-V88 and I2a2 subclades in the north Pontic Mesolithic, Neolithic, and Early Eneolithic Sredni Stog culture, until ca. 4500 BC (and even later, during the second half).

Only at the end of the Early Eneolithic with the disappearance of Novodanilovka (and beginning of the steppe ‘hiatus’ of Rassamakin) is R1a to be found in Ukraine again (after disappearing from the record some 2,000 years earlier), related to complex population movements in the north Pontic area.

NOTE. In the PCA, a tentative position of Novodanilovka closer to Anatolia_Neolithic / Dzudzuana ancestry is selected, based on the apparent cline formed by Ukraine_Eneolithic samples, and on the position and ancestry of Sredni Stog, Yamna, and Corded Ware later. A good alternative would be to place Novodanilovka still closer to the Balkan outliers (i.e. Suvorovo), and a source closer to EHG as the ancestry driven by the migration of R1a-M417.


The first sample with steppe ancestry appears only after 4250 BC in the forest-steppe, centuries after the samples with steppe ancestry from the Northern Caucasus and the Balkans, which points to exogamy of expanding R1a-M417 lineages with the remnants of the Novodanilovka population.


4. Repin / Early Yamna expansion

We don’t have direct data on early Repin settlers. But we do have a very close representative: Afanasevo, a population we know comes directly from the Repin/late Khvalynsk expansion ca. 3500/3300 BC (just before the emergence of Early Yamna), and which shows fully Steppe_Eneolithic-like ancestry.


Compared to this eastern Repin expansion that gave Afanasevo, the late Repin expansion to the west ca. 3300 BC that gave rise to the Yamna culture was one of colonization, evidenced by the admixture with north Pontic (Sredni Stog-like) populations, no doubt through exogamy:


This admixture is also found (in lesser proportion) in east Yamna groups, which supports the high mobility and exogamy practices among western and eastern Yamna clans, not only with locals:


5. Corded Ware

Corded Ware represents a quite homogeneous expansion of a late Sredni Stog population, compatible with the traditional location of Proto-Corded Ware peoples in the steppe-forest/forest zone of the Dnieper-Dniester region.


We don’t have a comparison with Ukraine_Eneolithic or Corded Ware samples in Wang et al. (2018), but we do have proximate sources for Abashevo, when compared to the Poltavka population (with which it admixed in the Volga-Ural steppes): Sintashta, Potapovka, Srubna (with further Abashevo contribution), and Andronovo:


The two CWC outliers from the Baltic show what I thought was an admixture with Yamna. However, given the previous mixture of Eneolithic_Steppe in north Pontic steppe-forest populations, this elevated “steppe ancestry” found in Baltic_LN (similar to west Yamna) seems rather an admixture of Baltic sub-Neolithic peoples with a north Pontic Eneolithic_Steppe-like population. Late Repin settlers also admixed with a similar population during its colonization of the north Pontic area, hence the Baltic_LN – west Yamna similarities.

NOTE. A direct admixture with west Yamna populations through exogamy by the ancestors of this Baltic population cannot be ruled out yet (without direct access to more samples), though, because of the contacts of Corded Ware with west Yamna settlers in the forest-steppe regions.


A similar case is found in the Yamna outlier from Mednikarovo south of the Danube. It would be absurd to think that Yamna from the Balkans comes from Corded Ware (or vice versa), just because the former is closer in the PCA to the latter than other Yamna samples. The same error is also found e.g. in the Corded Ware → Bell Beaker theory, because of their proximity in the PCA and their shared “steppe ancestry”. All those theories have been proven already wrong.

NOTE. A similar fallacy is found in potential Sintashta→Mycenaean connections, where we should distinguish statistically that result from an East/West Yamna + Balkans_BA admixture. In fact, genetic links of Mycenaeans with west Yamna settlers prove this (there are some related analyses in Anthrogenica, but the site is down at this moment). To try to relate these two populations (separated more than 1,000 years before Sintashta) is like comparing ancient populations to modern ones, without the intermediate samples to trace the real anthropological trail of what is found…Pure numbers and wishful thinking.


Yamna and Corded Ware show a similar “steppe ancestry” due to convergence. I have said so many times (see e.g. here). This was clear long ago, just by looking at the Y-chromosome bottlenecks that differentiate them – and Tomenable noticed this difference in ADMIXTURE from the supplementary materials in Mathieson et al. (2017), well before Wang et al. (2018).

This different stock stems from (1) completely different ancestral populations + (2) different, long-lasting Y-chromosome bottlenecks. Their similarities come from the two neighbouring cultures admixing with similar populations.

If all this does not mean anything, and each lab was going to support some pre-selected archaeological theories from the 1960s or the 1980s, coupled with outdated linguistic models no matter what – Anthony’s model + Ringe’s glottochronological tree of the early 2000s in the Reich Lab; and worse, Kristiansen’s CWC-IE + Germano-Slavonic models of the 1940s in the Copenhagen group – , I have to repeat my question again:

What’s (so much published) ancient DNA useful for, exactly?

Dzudzuana, Sidelkino, and the Caucasus contribution to the Pontic-Caspian steppe


It has been known for a long time that the Caucasus must have hosted many (at least partially) isolated populations, probably helped by geographical boundaries, setting it apart from open Eurasian areas.

David Reich writes in his book the following about India:

The genetic data told a clear story. Around a third of Indian groups experienced population bottlenecks as strong or stronger than the ones that occurred among Finns or Ashkenazi Jews. We later confirmed this finding in an even larger dataset that we collected working with Thangaraj: genetic data from more than 250 jati groups spread throughout India (…)

Rather than an invention of colonialism as Dirks suggested, long-term endogamy as embodied in India today in the institution of caste has been overwhelmingly important for millennia. (…)

The Han Chinese are truly a large population. They have been mixing freely for thousands of years. In contrast, there are few if any Indian groups that are demographically very large, and the degree of genetic differentiation among Indian jati groups living side by side in the same village is typically two to three times higher than the genetic differentiation between northern and southern Europeans. The truth is that India is composed of a large number of small populations.

There is little doubt now, based on findings spanning thousands of years, that the Mesolithic and Neolithic Caucasus hosted various very small populations, even if the ancestral components may be reduced to the few known to date (such as ANE, EHG, AME*, ENA, CHG, and other “deep” ancestral components).

NOTE. I will call the ancestral component of Dzudzuana/Anatolian hunter-gatherers Ancient Middle Easterner (AME), to give a clear idea of its likely extension during the Late Upper Palaeolithic, and to avoid using the more simplistic Dzudzuana, unless it is useful to mention these specific local samples.

Image modified from Lazaridis et al. (2018), including Caucasus, Don-Volga-Ural, and North Pontic Mesolithic-Neolithic populations. “Ancient West Eurasian population structure. (a) Geographical distribution of key ancient West Eurasian populations. (b) Temporal distribution of key ancient West Eurasian populations (approximate date in ky BP). (c) PCA of key ancient West Eurasians, including additional populations (shown with grey shells), in the space of outgroup f4-statistics (Methods).”

Genetic labs have a strong fixation with ancestry. I guess the use of complex statistical methods gives professionals and laymen alike the feeling of dealing with “Science”, as opposed to academic fields where you have to interpret data. I think language reveals a lot about the way people think, and the fact that ancestral components are called ‘lineages’ – while not wrong per se – is a clear symptom of the lack of interest in the true lineages: Y-DNA haplogroups.

Y-DNA bottlenecks

It has become quite clear that male-biased migrations are often the ones which can be confidently followed for actual population movements and ethnolinguistic identification, at least until the Iron Age. The frequently used Palaeolithic clusters offer a clear example of why ancestry does not represent what some people believe: They merely give a basic idea of sizeable population replacements by distant peoples.

Both concepts are important: sizeable and distant peoples. For example, during the Upper Palaeolithic in Europe there was a sizeable population replacement of the Aurignacian Goyet cluster by the Gravettian Vestonice cluster (probably from populations of far eastern Russia) coupled with the arrival of haplogroup I, although during the thousands of years that this material culture lasted, the previously expanded C1a2 lineages did not disappear, and there were probably different resurgence and admixture events.

Haplogroup I certainly expanded with the Gravettian culture to Iberia, where the Goyet ancestry did not change much – probably because of male-driven migrations -, to the extent that during the Magdalenian expansions haplogroup I expanded with an ancestry closer to Goyet, in what is called a ‘resurge’ of the Goyet cluster – even though there is a clear replacement of male lines.

The Villabruna (WHG) cluster is another good example. It probably spread with haplogroup R1b-L754, which – based on the extra ‘East Asian’ affinity of some samples and on modern samples from the Middle East – came probably from the east through a southern route, and not too long before the expansion of WHG likely from around the Black Sea, although this is still unclear. The finding of haplogroup I in samples of mostly WHG ancestry could confuse people that do not care about timing, sub-structured populations, and gene flow.

Image from David Reich’s Who We Are and How We Got Here. Having migrated out of Africa and the Near East, modern human pioneer populations spread throughout Eurasia (1). By at least thirty-nine thousand years ago, one group founded a lineage of European hunter-gatherers that persisted largely uninterrupted for more than twenty thousand years (2). Eventually, groups derived from an eastern branch of this founding population of European huntergatherers spread west (3), displaced previous groups, and were eventually themselves pushed out of northern Europe by the spread of glacial ice, shown at its maximum extent (top right). As the glaciers receded, western Europe was repeopled from the southwest (4) by a population that had managed to persist for tens of thousands of years and was related to an approximately thirty-five-thousand-year old individual from far western Europe. A later human migration, following the first strong warming period, had an even larger impact, with a spread from the southeast (5) that not only transformed the population of western Europe but also homogenized the populations of Europe and the Near East. At a single site—Goyet Caves in Belgium—ancient DNA from individuals spread over twenty thousand years reflects these transformations, with representatives from the Aurignacian, Gravettian, and Magdalenian periods.

NOTE. If you don’t understand why ‘clusters’ that span thousands of years don’t really matter for the many Palaeolithic population expansions that certainly happened among hunter-gatherers in Europe, just take a look at what happened with Bell Beakers expanding from Yamna into western Europe within 500 years.

If we don’t thread carefully when talking about population migrations, these terms are bound to confuse people. Just as the fixation on “steppe ancestry” – which marks the arrival in Chalcolithic Europe of peoples from the Pontic-Caspian region – has confused a lot of researchers to this day.

When I began to write about the Indo-European demic diffusion model, my concern was to find a single spot where a North-West Indo-European proto-language could have expanded from ca. 2000 BC (our most common guesstimate). Based on the 2015 papers, and in spite of their conclusions, I thought it had become clear that Corded Ware was not it, and it was rather Bell Beakers. I assumed that Uralic was spoken to the north (as was the traditional belief), and thus Corded Ware expanded from the forest zone, hence steppe ancestry would also be found there with other R1a lineages.

With the publication of Mathieson et al. (2017) and Olalde et al. (2017), I changed my mind, seeing how “steppe ancestry” did in fact appear quite late, hence it was likely to be the result of very specific population movements, probably directly from the Caucasus. Later, Mathieson published in a revision the sample from Alexandria of hg R1a-M417 (probably R1a-Z645, possibly Z93+), which further supported the idea that the migration of Corded Ware peoples started near the North Pontic forest-steppe (as I included in a the next revision).

The question remains the same I repeated recently, though: where do the extra Caucasus components (i.e. beyond EHG) of Eneolithic Ukraine/Corded Ware and Khvalynsk/Yamna come from?

Steppe ancestry: “EHG” + “CHG”?

About EHG ancestry

From Lazaridis et al. (2018):

Considering 2-way mixtures, we can model Karelia_HG as deriving 34 ± 2.8% of its ancestry from a Villabruna-related source, with the remainder mainly from ANE represented by the AfontovaGora3 (AG3) sample from Lake Baikal ~17kya.

AG3 was likely of haplogroup Q1a (as reported by YFull, see Genetiker), and probably the ANE ancestry found in Eastern Europe accompanied a Palaeolithic migration of Q1a2-M25 (formed ca. 22600 BC, TMRCA ca. 14300 BC).

NOTE. You can read more about the expansion of Q lineages during the Palaeolithic.

Combined with what we know about the Eneolithic Steppe and Caucasus populations – it is likely that ANE ancestry remained the most important component of some of the small ghost populations of the Caucasus until their emergence with the Lola culture.

Image modified from Wang et al. (2018). Samples projected in PCA of 84 modern-day West Eurasian populations (open symbols). Previously known clusters have been marked and referenced. Marked and labelled are the Balkan samples referenced in this text An EHG and a Caucasus ‘clouds’ have been drawn, leaving Pontic-Caspian steppe and derived groups between them. See the original file here. To understand the drawn potential Caucasus Mesolithic cluster, see above the PCA from Lazaridis et al. (2018).

The first sample we have now attributed to the EHG cluster is Sidelkino, from the Samara region (ca. 9300 BC), mtDNA U5a2. In Damgaard et al. (Science 2018), Yamnaya could be modelled as a CHG population related to Kotias Klde (54%) and the remaining from ANE population related to Sidelkino (>46%), with the following split events:

  1. A split event, where the CHG component of Yamnaya splits from KK1. The model inferred this time at 27 kya (though we note the larger models in Sections S2.12.4 and S2.12.5 inferred a more recent split time).
  2. A split event, where the ANE component of Yamnaya splits from Sidelkino. This was inferred at about about 11 kya.
  3. A split event, where the ANE component of Yamnaya splits from Botai. We inferred this to occur 17 kya. Note that this is above the Sidelkino split time, so our model infers Yamnaya to be more closely related to the EHG Sidelkino, as expected.
  4. An ancestral split event between the CHG and ANE ancestral populations. This was inferred to occur around 40 kya.

Other samples classified as of the EHG cluster:

  • Popovo2 (ca. 6250 BC) of hg J1, mtDNA U4d – Po2 and Po4 from the same site (ca. 6550 BC) show continuity of mtDNA.
  • Karelia_HG, from Juzhnii Oleni Ostrov (ca. 6300 BC): I0211/UzOO40 (ca. 6300 BC) of hg J1(xJ1a), mtDNA U4a; and I0061/UzOO74 of hg R1a1(xR1a1a), mtDNA C1
  • UzOO77 and UzOO76 from Juzhnii Oleni Ostrov (ca. 5250 BC) of mtDNA R1b.
  • Samara_HG from Lebyanzhinka (ca. 5600 BC) of hg R1b1a, mtDNA U5a1d.

From the analysis of Lazaridis et al. (2018), we have some details about their admixture:

Image modified from Lazaridis et al. (2018). Modeling present-day and ancient West-Eurasians. Mixture proportions computed with qpAdm (Supplementary Information section 4). The proportion of ‘Mbuti’ ancestry represents the total of ‘Deep’ ancestry from lineages that split prior to the split of Ust’Ishim, Tianyuan, and West Eurasians and can include both ‘Basal Eurasian’ and other (e.g., Sub-Saharan African) ancestry. (Left) ‘Conservative’ estimates. Each population 367 cannot be modeled with fewer admixture events than shown. (Right) ‘Speculative’ estimates. The highest number of sources (≤5) with admixture estimates within [0,1] are shown for each population. Some of the admixture proportions are not significantly different from 0 (Supplementary Information section 4).

About Anatolia_Neolithic ancestry

About the enigmatic Anatolia_Neolithic-related ancestry found in Pontic-Caspian steppe samples, this is what Wang et al. (2018) had to say:

We focused on model of mixture of proximal sources such as CHG and Anatolian Chalcolithic for all six groups of the Caucasus cluster (Eneolithic Caucasus, Maykop and Late Makyop, Maykop-Novosvobodnaya, Kura-Araxes, and Dolmen LBA), with admixture proportions on a genetic cline of 40-72% Anatolian Chalcolithic related and 28-60% CHG related (Supplementary Table 7). When we explored Romania_EN and Greece_Neolithic individuals as alternative southeast European sources (30-46% and 36-49%), the CHG proportions increased to 54-70% and 51-64%, respectively. We hypothesize that alternative models, replacing the Anatolian Chalcolithic individual with yet unsampled populations from eastern Anatolia, South Caucasus or northern Mesopotamia, would probably also provide a fit to the data from some of the tested Caucasus groups.


The first appearance of ‘Near Eastern farmer related ancestry’ in the steppe zone is evident in Steppe Maykop outliers. However, PCA results also suggest that Yamnaya and later groups of the West Eurasian steppe carry some farmer related ancestry as they are slightly shifted towards ‘European Neolithic groups’ in PC2 (Fig. 2D) compared to Eneolithic steppe. This is not the case for the preceding Eneolithic steppe individuals. The tilting cline is also confirmed by admixture f3-statistics, which provide statistically negative values for AG3 as one source and any Anatolian Neolithic related group as a second source

Modified image from Wang et al. (2018). In blue, Yamna-related populations. In red, Corded Ware-related populations, and two elevated Anatolia_Neolithic values in Yamna. Notice how only GAC-related admixture increases the Anatolian_N-related ancestry in the Yamna outlier from Ozero, and the late Yamna sample from Hungary, related to the homogeneous Yamna population. “Supplementary Table 14. P values of rank=3 and admixture proportions in modelling Steppe ancestry populations as a four-way admixture of distal sources EHG, CHG, Anatolian_Neolithic and WHG using 14 outgroups.Left populations: Steppe cluster, EHG, CHG, WHG, Anatolian_Neolithic. Right populations: Mbuti.DG, Ust_Ishim.DG, Kostenki14, MA1, Han.DG, Papuan.DG, Onge.DG, Villabruna, Vestonice16, ElMiron, Ethiopia_4500BP.SG, Karitiana.DG, Natufian, Iran_Ganj_Dareh_Neolithic.”

Detailed exploration via D-statistics in the form of D(EHG, steppe group; X, Mbuti) and D(Samara_Eneolithic, steppe group; X, Mbuti) show significantly negative D values for most of the steppe groups when X is a member of the Caucasus cluster or one of the Levant/Anatolia farmer-related groups (Supplementary Figs. 5 and 6). In addition, we used f- and D-statistics to explore the shared ancestry with Anatolian Neolithic as well as the reciprocal relationship between Anatolian- and Iranian farmer-related ancestry for all groups of our two main clusters and relevant adjacent regions (Supplementary Fig. 4). Here, we observe an increase in farmer-related ancestry (both Anatolian and Iranian) in our Steppe cluster, ranging from Eneolithic steppe to later groups. In Middle/Late Bronze Age groups especially to the north and east we observe a further increase of Anatolian farmer related ancestry consistent with previous studies of the Poltavka, Andronovo, Srubnaya and Sintashta groups and reflecting a different process not especially related to events in the Caucasus.

(…) Surprisingly, we found that a minimum of four streams of ancestry is needed to explain all eleven steppe ancestry groups tested, including previously published ones (Fig. 2; Supplementary Table 12). Importantly, our results show a subtle contribution of both Anatolian farmer-related ancestry and WHG-related ancestry (Fig.4; Supplementary Tables 13 and 14), which was likely contributed through Middle and Late Neolithic farming groups from adjacent regions in the West. The discovery of a quite old AME ancestry has rendered this probably unnecessary, because this admixture from an Anatolian-like ghost population could be driven even by small populations from the Caucasus.

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).”

NOTE. For a detailed account of the possibilities regarding this differential admixture in the North Pontic area in contrast to the Don-Volga-Ural region, you can read the posts Sredni Stog, Proto-Corded Ware, and their “steppe admixture”, and Corded Ware culture origins: The Final Frontier.

While it is not yet fully clear, the increased Anatolian_Neolithic-like ancestry in Ukraine_Eneolithic samples (see below) makes it unlikely that all such ancestry in Corded Ware groups comes from a GAC-related contribution. It is likely that at least part of it represents contributions from populations of the Caucasus, based on the mostly westward population movements in the steppe from ca. 4600 BC on, including the Suvorovo-Novodanilovka expansion, and especially the Kuban-Maykop expansion during the final Eneolithic into the North Pontic area.

NOTE. Since CHG-like groups from the Caucasus may have combinations of AME and ANE ancestry similar to Yamna (which may thus appear as ‘steppe ancestry’ in the North Pontic area), it is impossible to interpret with precision the following ADMIXTURE graphic:

Modified image from Mathieson et al. (2018). Supervised ADMIXTURE analysis, modelling each ancient individual (one per row) as a mixture of population clusters constrained to contain northwestern-Anatolian Neolithic (grey), Yamnaya from Samara (yellow), EHG (pink) and WHG (green) populations. Dates in parentheses indicate approximate range of individuals in each population.

North-Eastern Technocomplex

The East Asian contribution to samples from the WHG samples (like Loschbour or La Braña), as specified in Fu et al. (2016), does not seem to be related to Baikal_EN, and appears possibly (in the ADMIXTURE analysis) integrated into he Villabruna component. I guess this implies that the shared alleles with East Asians are quite early, and potentially due to the expansion of R1b-L754 from the East.

It would be interesting to know the specific material culture Sidelkino belonged to – i.e. if it was related to the expansion of the North-Eastern Technocomplex – , and its Y-DNA. The Post-Swiderian expansion into eastern Europe, probably associated with the expansion of R1b-P297 lineages (including R1b-M73, found later in Botai and in Baltic HG) is supposed to have begun during the 11th millennium BC, but migrations to the Urals and beyond are probably concentrated in the 9th millennium, so this sample is possibly slightly early for R1b.

NOTE. User Rozenfeld at Anthrogenica posted this, which I think is interesting (in case anyone wants to try a Y-SNP call):

there is something strange with Sidelkino EHG: first, its archaeological context is not described in the supplementary. Second, its sex is not listed in the supplementary tables. Third, after looking for info about this sample, I found that: “Сиделькино-3. Для снятия вопроса о половой принадлежности индивида была проведена генетическая экспертиза, выявившая принадлежность останков мужчине.”(translation: Sidelkino-3. To resolve the question about sex of the remains, the genetic analysis was conducted, which showed that remains belonged to male), source:

So either they haven’t mentioned his Y-DNA in the paper for some reason, or there are more than one Sidelkino sample and the male one has not yet been published. The coverage of the Sidelkino sample from the paper is 2.9, more than enough to tell Y-DNA haplogroup.

My speculative guess right now about specific population movements in far eastern Europe, based on the few data we have:

  • The expansion of the North-Eastern Technocomplex first around the 9th millennium BC, most likely expanded R1b-P279 ca. 11300 BC, judging by its TMRCA, with both R1b-M73 (TMRCA 5300) and R1b-M269 (TMRCA 4400 BC) info (with extra El Mirón ancestry) back, and thus Eurasiatic.
  • The expansion of haplogroup J1 to the north may have happened before or after the R1b-P279 expansion. Judging by the increase in AG3-related ancestry near Karelia compared to Baltic_HG, it is possible that it expanded just after R1b-P279 (hence possibly J1-Y6304? TMRCA 9700 BC). Its long-lasting presence in the Caucasus is supported by the Satsurblia (ca. 11300 BC) and the Dolmen BA (ca. 1300 BC) samples.
  • The expansion of R1a-M17 ca. 6600 BC is still likely to have happened from the east, based on the R1a-M17 samples found in Baikalic cultures slightly later (ca. 5300 BC). The presence of elevated Baikal_EN ancestry in Karelia HG and in Samara HG, and the finding of R1a-M417 samples in the Forest Zone after the Mesolithic suggests a connection with the expansion of Hunter-Gatherer pottery, from the Elshanka culture in the Samara region northward into the Forset Zone and westward into the North Pontic area.
  • The expansion of R1b-M73 ca. 5300 BC is likely to be associated with the emergence of a group east of the Urals (related to the later Botai culture, and potentially Pre-Yukaghir). Its presence in a Narva sample from Donkalnis (ca. 5200 BC) suggest either an early split and spread of both R1b-P297 lineages (M73 and M269) through Eastern Europe, or maybe a back-migration with hunter-gatherer pottery.
  • R1b-M269 spread successfully ca. 4400 BC (and R1b-L23 ca. 4100 BC, both based on TMRCA), and this successful expansion is probably to be associated with the Khvalynsk-Novodanilovka expansion. We already know that Samara_HG ca. 5600 was R1b1a, so it is likely that R1b-M269 appeared (or ‘resurged’) in the Volga-Ural region shortly after the expansion of R1a-M17, whose expansion through the region may be inferred by the additional AG3 and Baikal_EN ancestry. Interesting from Samara_HG compared to the previous Sidelkino sample is the introduction of more El Mirón-related ancestry, typical of WHG populations (and thus proper of Baltic groups).

NOTE. The TMRCA dates are obviously gross approximations, because a) the actual rate of mutation is unknown and b) TMRCA estimates are based on the convergence of lineages that survived. The potential finding of R1a-Z645 (possibly Z93+) in Ukraine Eneolithic (ca. 4000 BC), and the potential finding of R1b-L23 in Khvalynsk ca. 4250 BC complicates things further, in terms of dates and origins of any subclade.

The question thus remains as it was long ago: did R1b-M269 lineages expand (‘return’) from the east, near the Urals, or directly from the north? Were they already near Samara at the same time as the expansion of hunter-gatherer pottery, and were not much affected by it? Or did they ‘resurge’ from populations admixed with Caucasus-related ancestry after the expansion of R1a-M17 with this pottery (since there are different stepped expansions from the Samara region)? We could even ask, did R1a-M17 really expand from the east, i.e. are the dates on Baikalic subclades from Moussa et al. (2016) reliable? Or did R1a-M17 expand from some pockets in the Pontic-Caspian steppe, taking over the expansion of HG pottery at some point?

Maglemose-related migrations

The most interesting aspect from the new paper (regarding Indo-Uralic migrations) is that Ancestral Middle Easterner ancestry will probably be a better proxy for the Anatolia_Neolithic component found in Ukraine Mesolithic to Eneolithic, and possibly also for some of the “more CHG-like” component found among Pontic-Caspian steppe populations, all likely derived from different admixture events with groups from the Caucasus.

NOTE. Even the supposed gene flow of Neolithic Iranian ancestry into the Caucasus can be put into question, since that means possibly a Dzudzuana-like population with greater “deep ancestry” proportion than the one found in CHG, which may still be found within the Caucasus.

If it was not clear already that following ‘steppe ancestry’ wherever it appears is a rather lame way of following Indo-European migrations, every single sample from the Caucasus and their admixture with Pontic-Caspian steppe populations will probably show that “steppe ancestry” is in fact formed by a variety of steppe-related ancestral components, impossible to follow coherently with a single population. Exactly what is happening already with the Siberian ancestry.

If the paper on the Dzudzuana samples has shown something, is that the expansion of an ANE-like population shook the entire Caucasus area up to the Zagros Mountains, creating this ANE – AME cline that are CHG and Iran_N, with further contributions of “deep ancestries” (probably from the south) complicating the picture further.

If this happens with few known samples, and we know of an ANE-like ghost population in the Caucasus (appearing later in the Lola culture), we can already guess that the often repeated “CHG component” found in Ukraine_Eneolithic and Khvalynsk will not be the same (except the part mediated by the Novodanilovka expansion).

This ANE-like expansion happened probably in the Late Upper Palaeolithic, and reached Northern Europe probably after the expansion of the Villabruna cluster (ca. 12000 BC), judging by the advance of AG3-like and ENA-like ancestry in later WHG samples.

The population movements during the Mesolithic and Early Neolithic in the North Pontic area are quite complicated: the extra AME ancestry is probably connected to the admixture with populations from the Caucasus, while the close similarity of Ukraine populations with Scandinavian ones (with an increase in Villabruna ancestry from Mesolithic to Neolithic samples), probably reveal population movements related to the expansion of Maglemose-related groups.

Legend: 1 — Maglemose circle in the VII Mill. BC (after Gr. Clark); 2—7 — Mesolithic cultures of the Post-Maglemose tradition, VI Mill. BC (after S. Kozłowsky, L. L.

From Klein (2017).

These Maglemose-related groups were probably migrants from the north-west, originally from the Northern European Plains, who occupied the previous Swiderian territory, and then expanded into the North Pontic area. The overwhelming presence of I2a (likely all I2a2a1b1b) lineages in Ukraine Neolithic supports this migration.

The likely picture of Mesolithic-Neolithic migrations in the North Pontic area right now is then:

  1. Expansion of R1a-M459 from the east ca. 12000 BC – probably coupled with AG3 and also some Baikal_EN ancestry. First sample is I1819 from Vasilievka (ca. 8700 BC), another is from Dereivka ca. 6900 BC.
  2. Expansion of R1b-V88 from the Balkans in the west ca. 9700 BC, based on its TMRCA and also the Balkan hunter-gatherer population overwhemingly of this haplogroup from the 10th millennium until the Neolithic. First sample is I1734 from Vasilievka (ca. 7252 BC), which suggests that it replaced the male population there, based on their similar EHG-like adxmixture (and lack of sizeable WHG increase), and shared mtDNA U5b2, U5a2.
  3. Expansion of I2a-Y5606 probably ca. 6800 based on its TMRCA with Janislawice culture. Supporting this is the increase in WHG contribution to Neolithic samples, including the spread of U4 subclades compared to the previous period.
  4. Expansion of R1a-M17 starting probably ca. 6600 BC in the east (see above).

NOTE. The first sample of haplogroup I appears in the Mesolithic: I1763 (ca. 8100 BC) of haplogroup I2a1, probably related to an older Upper Palaeolithic expansion.

It is becoming more and more clear with each new paper that – unless the number of very ancient samples increases – the use of Y-chromosome haplogroups remains one of the most important tools for academics; this is especially so in the steppes, in light of the diversity found in populations from the Caucasus. A clear example comes from the Yamna – Corded Ware similarities:

After the publication of the 2015 papers, it was likely that Yamna expanded with haplogroup R1b-L23, but it has only become crystal clear that Yamna expanded through the steppes into Bell Beakers, now that we have data about the strict genetic homogeneity of the whole Yamna population from west to east (including Afanasevo), in contrast with contemporary Corded Ware peoples which expanded from a different forest-steppe population.

The presence of haplogroups Q and R1a-M459 (xM17) in Khvalynsk along with a R1b1a sample, which some interpreted as being akin to modern ‘mixed’ populations in the past, is likely to point instead to a period of Khvalynsk-Novodanilovka expansion with R1b-M269, where different small populations from the steppe were being integrated into the common Khvalynsk stock, but where differences are seen in material culture surrounding their burials, as supported by the finding of R1b1 in the Kuban area already in the first half of the 5th millennium. The case would be similar to the early ‘mixed’ Icelandic population.

Only after the emergence of the Samara culture (in the second half of the 6th millennium BC), with a sample of haplogroup R1b1a, starts then the obvious connection with Early Proto-Indo-Europeans; and only after the appearance of late Sredni Stog and haplogroup R1a-M417 (ca. 4000 BC) is its connection with Uralic also clear. In previous population movements, I think more haplogroups were involved in migrations of small groups, and only some communities among them were eventually successful, expanding to be dominant, creating ever growing cultures during their expansions.

Indeed, if you think in terms of Uralic and Indo-European just as converging languages, and forget their potential genetic connection, then the genetic + linguistic picture becomes simplified, and the upper frontier of the 6th millennium BC with a division North Pontic (Mariupol) vs. Volga-Ural (Samara) is enough. However, tracing their movements backwards – with cultural expansions from west to east (with the expansion of farming), and earlier east to west (with hunter-gatherer pottery), and still earlier west to east (with the north-eastern technocomplex), offers an interesting way to prove their potential connection to macrofamilies, at least in terms of population movements.

Modified image from Tambets et al. (2018) Proportions of ancestral components in studied European and Siberian populations and the tested qpGraph model. a The qpGraph model fitting the data for the tested populations. Colour codes for the terminal nodes: pink—modern populations (‘Population X’ refers to test population) and yellow—ancient populations (aDNA samples and their pools). Nodes coloured other than pink or yellow are hypothetical intermediate populations. We putatively named nodes which we used as admixture sources using the main recipient among known populations. The colours of intermediate nodes on the qpGraph model match those on the admixture proportions panel. The NeolL (Neolithic Levant) ancestry selected in this qpGraph is likely to correspond (at least in part) to a specific Dzudzuana-like component present in the CHG-like population that admixed in the North Pontic area.

I am quite convinced right now that it would be possible to connect the expansion of R1b-L754 subclades with a speculative Nostratic (given the R1b-V88 connection with Afroasiatic, and the obvious connection of R1b-L297 with Eurasiatic). Paradoxically, the connection of an Indo-Uralic community in the steppes (after the separation of Yukaghir) with any lineage expansion (R1a-M17, R1b-M269, or even Q, I or J1) seems somehow blurrier than one year ago, possibly just because there are too many open possibilities.

David Reich says about the admixture with Neanderthals, which he helped discover:

At the conclusion of the Neanderthal genome project, I am still amazed by the surprises we encountered. Having found the first evidence of interbreeding between Neanderthals and modern humans, I continue to have nightmares that the finding is some kind of mistake. But the data are sternly consistent: the evidence for Neanderthal interbreeding turns out to be everywhere. As we continue to do genetic work, we keep encountering more and more patterns that reflect the extraordinary impact this interbreeding has had on the genomes of people living today.

I think this is a shared feeling among many of us who have made proposals about anything, to fear that we have made a gross, evident mistake, and constantly look for flaws. However, it seems to me that geneticists are more preoccupied with being wrong in their developed statistical methods, in the theoretical models they are creating, and not so much about errors in the true ancient ethnolinguistic picture human population genetics is (at least in theory) concerned about. Their publications are, after all, constantly associating genetic finds with cultures and (whenever possible) languages, so this aspect of their research should not be taken lightly.

Seeing how David Anthony or Razib Khan (among many others) have changed their previously preferred migration models as new data was published, and they continue to be respected in their own fields, I guess we can be confident that professionals with integrity are going to accept whatever new picture appears. While I don’t think that genetic finds can change what we can reconstruct with comparative grammar, I am also ready to revise guesstimates and routes of expansion of certain dialects if R1a-Z645 is shown to have accompanied Late Proto-Indo-Europeans during their expansion with Yamna, and later integrated somehow with Corded Ware.

However, taking into account the obsession of some with an ancestral, uninterrupted R1a—Indo-European association, and the lack of actual political repercussion of Neanderthal admixture, I think the most common nightmare that all genetic researchers should be worried about is to keep inflating this “Yamnaya ancestry”-based hornet’s nest, which has been constantly stirred up for the past two years, by rejecting it – or, rather, specifying it into its true complex nature.

This succession of corrections and redefinitions, coupled with the distinct Y-DNA bottleneck of each steppe population, will eventually lead to a completely different ethnolinguistic picture of the Pontic-Caspian region during the Eneolithic, which is likely to eventually piss off not only reasonable academics stubbornly attached to the CWC-IE idea, but also a part of those interested in daydreaming about their patrilineal ancestors.

Sometimes it’s better to just rip off the band-aid once and for all…

Russian colonization in Yakutia

Exploring the genomic impact of colonization in north-eastern Siberia, by Seguin-Orlando et al.

Yakutia is the coldest region in the northern hemisphere, with winter record temperatures below minus 70°C. The ability of Yakut people to adapt both culturally and biologically to extremely cold temperatures has been key to their subsistence. They are believed to descend from an ancestral population, which left its original homeland in the Lake Baykal area following the Mongol expansion between the 13th and 15th centuries AD. They originally developed a semi-nomadic lifestyle, based on horse and cattle breeding, providing transportation, primary clothing material, meat, and milk. The early colonization by Russians in the first half of the 17th century AD, and their further expansion, have massively impacted indigenous populations. It led not only to massive epidemiological outbreaks, but also to an important dietary shift increasingly relying on carbohydrate-rich resources, and a profound lifestyle transition with the gradual conversion from Shamanism to Christianity and the establishment of new marriage customs. Leveraging an exceptional archaeological collection of more than a hundred of bodies excavated by MAFSO (Mission Archéologique Française en Sibérie Orientale) over the last 15 years and naturally kept frozen by the extreme cold temperatures of Yakutia, we have started to characterize the (epi)genome of indigenous individuals who lived from the 16th to the 20th century AD. Current data include the genome sequence of approximately 50 individuals that lived prior to and after Russian contact, at a coverage from 2 to 40 fold. Combined with data from archaeology and physical anthropology, as well as microbial DNA preserved in the specimens, our unique dataset is aimed at assessing the biological consequences of the social and biological changes undergone by the Yakut people following their neolithisation by Russian colons.

Ancient DNA from a Medieval trading centre in Northern Finland

Using ancient DNA to identify the ancestry of individuals from a Medieval trading centre in Northern Finland, by Simoes et al.

Analyzing genomic information from archaeological human remains has proved to be a powerful approach to understand human history. For the archaeological site of Ii Hamina, ancient DNA can be used to infer the ancestries of individuals buried there. Situated approximately 30 km from Oulu, in Northern Finland, Ii Hamina was an important trade place since Medieval times. The historical context indicates that the site could have been a melting pot for different cultures and people of diversified genetic backgrounds. Archaeological and osteological evidence from different individuals suggest a rich diversity. For example, stable isotope analyses indicate that freshwater and marine fish was the dominant protein source for this population. However, one individual proved to be an outlier, with a diet containing relatively more terrestrial meat or vegetables. The variety of artefacts that was found associated with several human remains also points to potential differences in religious beliefs or social status. In this study, we aimed to investigate if such variation could be attributed to different genetic ancestries. Ten of the individuals buried in Ii Hamina’s churchyard, dating to between the 15th and 17th century AD, were screened for presence of authentic ancient DNA. We retrieved genome-wide data for six of the individuals and performed downstream analysis. Data authenticity was confirmed by DNA damage patterns and low estimates of mitochondrial contamination. The relatively recent age of these human remains allows for a direct comparison to modern populations. A combination of population genetics methods was undertaken to characterize their genetic structure, and identify potential familiar relationships. We found a high diversity of mitochondrial lineages at the site. In spite of the putatively distant origin of some of the artifacts, most individuals shared a higher affinity to the present-day Finnish or Late Settlement Finnish populations. Interestingly, different methods consistently suggested that the individual with outlier isotopic values had a different genetic origin, being more closely related to reindeer herding Saami. Here we show how data from different sources, such as stable isotopes, can be intersected with ancient DNA in order to get a more comprehensive understanding of the human past.

Plant resources processed in HG pottery from the Upper Volga

Multiple criteria for the detection of plant resources processed in hunter-gatherer pottery vessels from the Upper Volga, Russia, by Bondetti et al.

In Northern Eurasia, the Neolithic is marked by the adoption of pottery by hunter-gatherer communities. The degree to which this is related to wider social and lifestyle changes is subject to ongoing debate and the focus of a new research programme. The use and function of early pottery by pre-agricultural societies during the 7th-5th millennia BC is of central interest to this debate. Organic residue analysis provides important information about pottery use. This approach relies on the identification and isotopic characteristics of lipid biomarkers, absorbed into the pores of the ceramic or charred deposits adhering to pottery vessel surfaces, using a combined methodology, namely GC-MS, GC-c-IRMS and EA-IRMS. However, while animal products (e.g., marine, freshwater, ruminant, porcine) have the benefit of being lipid-rich and well-characterised at the molecular and isotopic level, the identification of plant resources still suffers from a lack of specific criteria for identification. In huntergatherer contexts this problem is exacerbated by the wide range of wild, foraged plant resources that may have been potentially exploited. Here we evaluate approaches for the characterisation of terrestrial plant food in pottery through the study of pottery assemblages from Zamostje 2 and Sakhtysh 2a, two hunter-gatherer settlements located in the Upper Volga region of Russia.

GC-MS analysis of the lipids, extracted from the ceramics and charred residues by acidified methanol, suggests that pottery use was primarily oriented towards terrestrial and aquatic animal products. However, while many of the Early Neolithic vessels contain lipids distinctive of freshwater resources, triterpenoids are also present in high abundance suggesting mixing with plant products. When considering the isotopic criteria, we suggest that plants were a major commodity processed in pottery at this time. This is supported by the microscopic identification of Viburnum (Viburnum Opulus L.) berries in the charred deposits on several vessels from Zamostje.

The study of Upper Volga pottery demonstrated the importance of using a multidisciplinary approach to determine the presence of plant resources in vessels. Furthermore, this informs the selection of samples, often subject to freshwater reservoir effects, for 14C dating.

Studies on hunter-gatherer pottery – appearing in eastern Europe before Middle Eastern Neolithic pottery – may be important to understand the arrival of R1a-M17 lineages to the region before ca. 7000 BC. Or not, right now it is not very clear what happened with R1b-P297 and R1a-M17, and with WHG—EHG—ANE ancestry

Bronze Age population dynamics and the rise of dairy pastoralism on the eastern Eurasian steppe

Bronze Age population dynamics and the rise of dairy pastoralism on the eastern Eurasian steppe, by Warinner et al.

Recent paleogenomic studies have shown that migrations of Western steppe herders (WSH), beginning in the Eneolithic (ca. 3300-2700 BCE), profoundly transformed the genes and cultures of Europe and Central Asia. Compared to Europe, the eastern extent of this WSH expansion is not well defined. Here we present genomic and proteomic data from 22 directly dated Bronze Age khirigsuur burials from Khövsgöl, Mongolia (ca. 1380-975 BCE). Only one individual showed evidence of WSH ancestry, despite the presence of WSH populations in the nearby Altai-Sayan region for more than a millennium. At the same time, LCMS/ MS analysis of dental calculus provides direct protein evidence of milk consumption from Western domesticated livestock in 7 of 9 individuals. Our results show that dairy pastoralism was adopted by Bronze Age Mongolians despite minimal genetic exchange with Western steppe herders.

The origin of social complexity in the development of the Sintashta culture


Very interesting PhD thesis by Igor Chechushkov, Bronze Age human communities in the Southern Urals steppe: Sintashta-Petrovka social and subsistence organization (2018).


Why and how exactly social complexity develops through time from small-scale groups to the level of large and complex institutions is an essential social science question. Through studying the Late Bronze Age Sintashta-Petrovka chiefdoms of the southern Urals (cal. 2050–1750 BC), this research aims to contribute to an understanding of variation in the organization of local communities in chiefdoms. It set out to document a segment of the Sintashta-Petrovka population not previously recognized in the archaeological record and learn about how this segment of the population related to the rest of the society. The Sintashta-Petrovka development provides a comparative case study of a pastoral society divided into sedentary and mobile segments.

Subsurface testing on the peripheries of three Sintashta-Petrovka communities suggests that a group of mobile herders lived outside the walls of the nucleated villages on a seasonal basis. During the summer, this group moved away from the village to pasture livestock farther off in the valley, and during the winter returned to shelter adjacent to the settlement. This finding illuminates the functioning of the year-round settlements as centers of production during the summer so as to provide for herd maintenance and breeding and winter shelter against harsh environmental conditions.

The question of why individuals chose in this context to form mutually dependent relationships with other families and thus give up some of their independence can be answered with a combination of two necessities: to remain a community in a newly settled ecological niche and to protect animals from environmental risk and theft. Those who were skillful at managing communal construction of walled villages and protecting people from military threats became the most prominent members of the society. These people formed the core of the chiefdoms but were not able to accumulate much wealth and other possessions. Instead, they acquired high social prestige that could even be transferred to their children. However, this set of relationships did not last longer than 300 years. Once occupation of the region was well established the need for functions served by elites disappeared, and centralized chiefly communities disintegrated into smaller unfortified villages.

Some interesting excerpts (emphasis mine):

The quintessential archaeological evidence of Sintashta-Petrovka communities takes the form of highly nucleated and fortified settlements paired with easily-recognized kurgan (burial mound) cemeteries. This pattern spread across Northern Central Eurasia in a relatively short period of about 300 years (cal. 2050–1750 BC), and the period consists of two chronological phases (Hanks et al. 2007). The earlier Sintashta phase (cal. 2050–1850 BC) is distinguished from the later Petrovka phase (cal. 1850–1750 BC) by some differences in ceramic styles and some techniques of bronze metallurgy (Degtyareva et al. 2001; Vinogradov 2013). Bronze Age subsistence patterns apparently relied on a wide variety of resources, among which meat and milk production played a major role (…). The most outstanding graves are individual male burials accompanied by weaponry (projectile weapons and chariots), the insignia of power (stone mace heads), craft tools, and a specific set of sacrificed animals (horses, cows, and dogs). (…) there were at least two adults buried with chariots and one with sacrificed horses (Epimakhov 1996b). Chariots – the most famous and spectacular material component of Sintashta-Petrovka society – are known exclusively from burial contexts. Two-wheeled vehicles represent complex technology, incorporating some crucial innovations and the investment of substantial resources. Highly developed craft and military skills were required for their production and use. Burials with chariots probably represent military elites who used them (Anthony 2009; Chechushkov 2011; Frachetti 2012:17) and played especially important social roles in Sintashta-Petrovka societies. This pattern strongly suggests that military leadership extended into the realm of ideology and general social prestige (Earle 2011:32–33).

The following sequence of archaeological cultures – based on the sample of radiocarbon dates (Epimakhov 2007a; 2010a), – is adopted: (1) the Sintashta-Petrovka phase 1 dated to cal. 2050–1750 BC and (2) the Srubnaya-Alakul’ phase 2 dated to cal. 1750–1350 BC.

(…) control of craft might have provided a source of power for elites in the fortified settlements (Steponaitis 1991). Some bronze tools, such as chisels, adzes, and handsaws seem more abundantly represented at some fortified settlements than at others, raising the possibility of a stronger focus on different craft products and some degree of exchange and interdependence between fortified settlements. (…) Zdanovich (1995:35) estimates 2500 people within the walls at Arkaim. He bases his conclusion an average house size of 140 m2 and the idea that Arkaim households consisted of an extended family of several generations, similar to Iroquois longhouse inhabitants. He also suggests that the entire population did not live in the “town” all the time, but moved around. The fully permanent residents were shamans, warriors, and craftsmen, i.e., elites and attached specialists.

Summarizing, excavated households represent very strongly similar architectural patterns, similar levels of wealth and prestige, little productive differentiation, and no evidence of elites amassing wealth through control of craft or subsistence production or any other mechanism (Earle 1987). These observations sharply contradict the burial record, where strong social differentiation is visible. The description above recalls the Regional Classic period elites of the Alto Magdalena whose standard of living differed little if at all from anyone else’s. Their elaborate tombs and sculptures suggest supernatural powers and ritual roles were much more important bases of their social prominence than economic control or accumulation of wealth (Drennan 1995:96–97). On the other hand, craft activities (especially metal production) are highly obvious in the Sintashta-Petrovka settlements. Defensive functions could also have played some role for the entire population. This benefit might attract people in an unstable or wild environment to spend much of their time in or near such settlements (Earle 2011:32–33). Since the construction of ditches and outer walls, as well as dwellings with shared walls, requires planning and organization, purposeful collective effort must have been a key feature of Sintashta-Petrovka communities (Vinogradov 2013; Zdanovich 1995). Sintashta-Petrovka communities thus evidence substantial investment of effort in non-subsistence activities, potentially resulting in a subsistence deficit in an economy with a heavy emphasis on herding. Altogether, this makes it plausible to think of the known Sintashta-Petrovka communities as special places where elites for whom military activities were important resided, and where metal production and possibly other crafts were carried out. It remains unclear just how a subsistence economy relying heavily on herding was managed from these substantial sedentary communities. Moving herds around the landscape seasonally is generally thought to be a part of subsistence strategy in Inner Eurasia (Frachetti 2008; Bachura 2013). In this area migration to exploit seasonal pastures is the best strategy for maintaining a regular supply of food for livestock due to shortages of capital or of labor pool to produce, harvest, and store fodder (Dyson-Hudson and Dyson-Hudson 1980:17). The recent stable isotope studies support this notion showing high likelihood that during the Bronze Age livestock was raised locally (Kiseleva et al. 2017).

The above raises the possibility that the residential remains that have been excavated within the fortifications of Sintashta-Petrovka communities represent only a portion of the population (Hanks and Doonan 2009, Johnson and Hanks 2012). It could be (along with the general lines suggested by D. Zdanovich [1997]) that the archaeological remains of the ordinary people who made up the majority of the population, built the impressive fortifications and stoked the subsistence economy have gone largely undetected. In global comparative perspective, many societies with the features known for Sintashta-Petrovka organization consisted of elite central-place settlements and hinterland populations. In such a scenario, the “missing” portion of the Sintashta population would reside in smaller unfortified settlements scattered around in the vicinity of the fortified ones.


In terms of wealth and productive differentiation, the inside assemblage of Kamennyi Ambar demonstrates a higher degree of richness and diversity in its material assemblage, leading to the conclusion that the outside materials may represent a semi-mobile group of people who used significantly less durable materials and accumulated less possessions. As for the diversity within the inside artifact assemblage, some households at Kamennyi Ambar demonstrate more diverse artifact assemblages than others, as well as bigger sizes, that could be related to differences in productive activities and/or wealth differentiation between families. A focus on specific objects of ceramic production in House 1 suggests some degree of productive specialization, while the elite goods in House 5 clearly point out the presence of elite members of the society.

There are two possible social scenarios that explain the settlement situation during the Sintashta-Petrovka phase. The first scenario considers all three communities as simultaneous and the second scenario suggests seeing the three sites as the same community that moved around the landscape during the Late Bronze Age in order to keep the pasture grounds from degradation.

Since no remains of permanent structures were found and any people living outside the walls must have stayed in temporary shelters. If this was the case, then the outside part of the population consisted of a semi-mobile group of people who moved to live near the fortified settlement during the winter. The pattern of animal slaughtering supports this conclusion. Animal teeth found near Kamennyi Ambar and Konoplyanka demonstrate a tendency for animal butchering during the fall, throughout the winter and spring, with less evidence of summer meat consumption. Moreover, since the Bronze Age subsistence strategy relied heavily on pastoralism, herds had to be grazed during the summer and kept safe during the winter. This strongly suggests that the part of the population responsible for management of animals spent their time in the summer pastures with the livestock. During the winter the animals had to be kept in the warm and safe environment of the walled settlements (as suggested by the highest level of phosphorus on the house floors) while the herders stayed in portable shelters in close to the walls.

(…) the outsiders used a less diverse set of tools, as well as less durable materials (for example, wooden instead of metal) in their everyday life and did not accumulate much in the way of archaeologically visible possessions. On the other hand, a few stone and lithic artifacts demonstrate that craft activities were carried out using cheap and abundant raw materials. The artefact assemblages also point out that the people inside accumulated wealth in the form of material belongings and luxury goods, especially, things like metal artifacts and symbolic or military-related stone artifacts, while people outside did not do that. However, the presence of semi-precious stones could signify some kind of wealth accumulation by the segment of population outside the walls. Since there are limits to our ability to assess social relationships from material remains, it is difficult to say if the people who lived outside the walls were oppressed or less respected. Their possible concentration on herding-related activities and livestock keeping might suggest less prestigious social status. The most prominent members of the society were, nonetheless, buried with the attributes of warriors or craft specialists, not those of shepherds, suggesting that those involved in livestock management had less social prestige.

Furthermore, Kuzmina (1994:72) cites linguistic studies demonstrating that the Sanskrit word for a permanent village earlier meant a circle of mobile wagon homes, situated together for defensive purposes for an overnight camp (Kuzmina 1994:72).

The likely population of semi-mobile herders represented some 30%–60% of the entire local community, while the other of 40%–70% were inhabitants of the walled settlement. The almost completely excavated kurgan cemetery of Kamennyi Ambar-5 (only two kurgans remain unstudied) yielded about 100 individuals, or about 2%–5% of the total of 4,896±1,960 individuals in four generations who lived at the nearby settlement for 100 years. In other words, no more than 10% of the population was entitled to be buried under the kurgan mound and this proportion can be taken as an estimate of those with elevated social status. Perhaps, these elites were kin, since analysis of the burial patterns suggests sex/age rather than wealth/prestige differentiation between buried individuals within this elite group (Epimakhov and Berseneva 2011; Ventresca Miller 2013). The remaining non-elite members of the permanently resident community, then, represented some 30%–60% of the complete local community, but did not show evidence of standards of living particularly lower than the elites eventually interred in the kurgan.

(…) The buried population in the Sintashta Cemetery is about 80 individuals or only about 2%–3% of the total estimated population. However, these few individuals were buried with extremely rich offerings, like complete chariots, decorations made of precious metals or sacrifices of six horses (equal to about 900 kg of meat), etc. With such a low proportion of the population assigned such high prestige, the Sintashta local community can easily be labeled a local chiefdom. In Pitman and Doonan’s view (2018) the social structure of the chifedom consisted of a chief and his kin at the highest level; warriors, religious specialists, and craftsmen in the middle; and the pastoral community at the bottom level.


In the Bronze Age, the people who comprised the majority of the permanent population were involved in craft activities, including extraction of copper ores, metallurgy, bone, leather, and woodwork. The most important and labor-intensive part of the economy, however, was haymaking. The evidence of hay found in the cultural layer near Kamennyi Ambar supports the idea that animals were fed during the winter. Nowadays, hay cutting is typically done in July-August, the period of most intensive grazing for animals. Thus, the part of the collective that remained in the settlement had to provide the labor force for haymaking.

In the wintertime, the herders returned to the settlements with the herds, and animals were kept inside the walls––a practice which is known archaeologically (Zakh 1995) and ethnographically (Shahack-Gross et al. 2004)––while herders stayed outside in their tents.

In sum, the Sintashta-Petrovka chiefdoms demonstrate a three-part social order. In Kuzmina’s (1994) view, this is similar to the Varna system of ancient India, that consisted of priests (Sansk. Brahmanis), rulers and warriors (Sansk. Kshatriyas), free producers (Sansk. Vaishyas) and laborers and service providers (Sansk. Shudras). In the Sintashta-Petrovka chiefdom, the elite 2%–5% of the population would have consisted of priests and warriors; 48%–55% would have been dependent producers; and 50%–60% would have been herders of lower social rank.

In the case of the Sintashta-Petrovka chiefdoms, the questions of why and how exactly social complexity developed through time and why individuals choose to integrate and give up their independence can be answered as some combination of two necessities: to persist as a larger community in the ecological niche of the newly settled region, and to protect herds from theft.

There is general agreement among researchers that the Sintashta phenomenon had no local roots and originated with a large-scale migration of pastoral communities from Eastern Europe to the marginal area of the Southern Urals. This process forced families to stay together and fueled the necessity in the walled villages for ensuring the reproduction of herds in the extreme climatic conditions of the southern Urals that are colder and dryer than the eastern Black Sea region from which the Sintashta populations are thought to have migrated (Kuzmina 1994, 2007; Anthony 2007; Vinogradov 2011, etc.). At the same time, the herds needed protection from animal and human predators. Probably, the risk of losing animals was a threat to survival that created tensions between neighboring communities, and the Neolithic hunter-gatherers who had populated the Urals before the arrival of Sintashta people could have hunted the domestic animals. Apparently, those who were talented in managing the construction of closely-packed villages surrounded by ditches and walls to protect people and livestock from threats from neighbors, and who otherwise served the community in the newly colonized zone became the most prominent members of society. Theses people formed the core of the Sintashta-Petrovka chiefdom but were not able to accumulate much personal wealth in the form of material possessions. Instead, they acquired high social prestige that could even be transferred to their children (since up to 65% of the buried elite population consists of infants [Razhev and Epimakhov 2005). In this sense, the Sintashta-Petrovka elites were simmilar to their counterparts in the Alto Magdalena of Colombia (Drennan 1995; Gonzalez Fernandez 2007; Drennan and Peterson 2008).

However, this situation did not last longer than 300 years, since after the initial phase of colonization of the Southern Urals was over, the need for social services provided by an elite disappeared and centralized chiefly communities disintegrated into the smaller unfortified villages of the Srubnaya-Alakul’ period.

As I have said many times already (see e.g. here) the outsider pastoralists, forming originally the vast majority of the population, were most likely Pre-Proto-Indo-Iranian speakers of haplogroup R1b-Z2103, and their elite groups (whose inheritance system was based on kinship) probably incorporated gradually Uralic-speaking families of haplogroup R1a-Z93, whose relative importance increased gradually, and then eventually expanded massively with the migrations of Andronovo and Srubna, creating a second Y-chromosome bottleneck that favoured again Z93 subclades. The adaptation of Pre-Proto-Indo-Iranian to the Uralic pronunciation, and the adoption of PII vocabulary in neighbouring Proto-Finno-Ugric bear witness to this process.
