A Late Proto-Indo-European self-learning language course

guidebook-ie

Fernando López-Menchero has just published the first part of his A Practical Guidebook for Modern Indo-European Explorers (2018).

It is a great resource to learn Late Proto-Indo-European as a modern language, from the most basic level up to an intermediate level (estimated B1–B2, depending on one’s previous background in Indo-European and classical languages).

Instead of working on unending details and discussions of the language reconstruction, it takes Late Proto-Indo-European as a learned, modern language that can be used for communication, so that people not used to study with university manuals on comparative grammar can learn almost everything necessary about PIE in the most comfortable way.

(see also the announcement on Facebook)

NOTE. Even though we help each other with our works, Fernando is not the least interested in genetics (the “steppe ancestry” or the “R1b–R1a” question, or any other issue involving population genomics), or even too much about archaeology or the homeland question (although he uses the mainstream view that Late Proto-Indo-Europeans expanded from Yamna). His only interest is language reconstruction, and I doubt you can find anything else in his works but pure love for linguistics, including this one.

I was starting to call his project of a self-learning method The Winds of Winter, seeing how it appeared to be always in the making, but never actually finished. It seems that the publication of this first part will make my revision of the Indo-European demic diffusion model become the true The Winds of Winter here, in this our common series of books on Late Proto-Indo-European and its dialects…

As you can see, I am publishing less and less in this blog lately, and it’s all just to be able to finish a revision in time (that is, before more new genetic research compels me to delay it again…). It is a very thorough revision, so those of you who liked it are not going to be disappointed.

I hoped to have it ready for mid-December, but, as it turns out, due to different unexpected delays, I am now more confident about a mid-January / February date, and that only if everything goes well.

On the origin of haplogroup R1b-L51 in late Repin / early Yamna settlers

steppe-eneolithic-migrations

A recent comment on the hypothetical Central European origin of PIE helped me remember that, when news appeared that R1b-L51 had been found in Khvalynsk ca. 4250-4000 BC, I began to think about alternative scenarios for the expansion of this haplogroup, with one of them including Central Europe.

Because, if YFull‘s (and Iain McDonald‘s) estimation of the split of R1b-L23 in L51 and Z2103 (ca. 4100 BC, TMRCA ca. 3700 BC) was wrong, by as much as the R1a-Z645 estimates proved wrong, and both subclades were older than expected, then maybe R1b-L51 was not part of the Yamna expansion, but rather part of an earlier expansion with Suvorovo-Novodanilovka into central Europe.

That is, R1b-L51 and R1b-Z2103 would have expanded wih Khvalynsk-Novodanilovka migrants, and they would have either disappeared among local populations, or settled and expanded with successful lineages in certain regions. I think this may give rise to two potential models.

A hidden group in the European east-central steppes?

Here is what Heyd (2011), for example, has to say about the effect of the Khvalynsk-Novodanilovka expansion in the 4th millennium BC, with the first Kurgan wave that shuttered the social, economic, and cultural foundations of south-eastern Europe (before the expansion of west Yamna migrants in the region):

As the Boleraz and Baden tumuli cases in Serbia and Hungary demonstrate, there are earlier, 4th millennium cal. B.C. round tumuli in the Carpathian basin. There are also earlier north-Pontic steppe populations who infiltrated similar environments west of the Black Sea prior to the rise of the Yamnaya culture. This situation can be traced back to the 2nd half of the 5th millennium cal. B.C. to a group of distinct burials, zoomorphic maceheads, long flint blades, triangular flint points, etc., summarized under the term Suvurovo-Novodanilovka (Govedarica 2004; Rassamakin 2004; Anthony 2007; Heyd forthcoming 2011). They also erected round personalized tumuli, though smaller in size and height, above inhumations of single individuals. Suvorovo and Casimcea are the key examples in the lower Danube region of Romania. In northeast Bulgaria, the primary grave of Polska Kosovo (ochre-stained supine extended body position: information communicated by S. Alexandrov) can also be seen as such, as should the Targovishte-“Gonova mogila” primary grave 1 in the Thracian plain with a burial arranged in a supine position with flexed legs, southeast-northwest orientated, and strewed with ochre (Kanchev 1991 , p. 56- 57; Ivanova Gaydarska 2007). In addition to the many copper and shell beads, the 17.4cm long obsidian blade is exceptional, which links this grave to the Csongrád-“Kettoshalom” grave in the south Hungarian plain (Ecsedy 1979). It also yielded an obsidian blade ( 13.2cm long) and copper, shell and limestone beads.

The Southeast European distribution of graves of the Suvorovo-Novodanilovka group and such unequipped ones mentioned in the text which can be attributed by burial custom and stratigraphic position in the barrow, plus zoomorphic and abstract animal head sceptres as well as specific maceheads with knobs as from Decea Maresului (mid-5th millennium until around 4000 BC). Heyd (2016).

However, no traces of a tumulus have been recorded above the Kettoshalom tomb. Conventionally, it is dated to the Bodrogkeresztur-period in east Hungary, shortly after 4000 cal. B.C., which would correspond very well with the suggested Cernavodă I (or its less known cultural equivalent in the Thracian plain) attribution for the “Gonova mogila” grave, a cultural background to which the Csongrád grave should have also belonged. Bodrogkeresztur and Cernavodă I periods are not the only examples of 4th millennium cal. B.C. tumuli and burials displaying this steppe connection. Indeed we can find this early steppe impact throughout the 4th millennium cal. B.C. These include adscriptions to the Horodiștea II (Corlateni-Dealul Stadole, grave I: Burtanescu l 998, p. 37; Holbocai, grave 34: Coma 1998, p. 16); to Gordinești-Cernavodă 11 (Liești-Movila Arbănașu, grave 22: Brudiu 2000); to Gorodsk-Usatovo (Corlăteni Dealul Cetăţii, grave I: Comșa 1998, p. 17- 18, in Romania; Durankulak, grave 982: Vajsov 2002, in Bulgaria); and to Cernavodă III(Golyama Detelina, tum. 4: Leshtakov, Borisov 1995), and early (end of 4th millennium cal. B.C.) Ezero in Ovchartsi, primary grave (Kalchev 1994, p. 134-138) and Golyama Detelina, tum. 2 (Kanchev 1991) in Bulgaria. Also the Boleráz and Baden tumuli of Banjevac-Tolisavac and Mokrin in the south Carpathian basin account for this, since one should perhaps take into account primary grave 12 of the Sárrédtudavari-Orhalom tumulus in the Hungarian Alfold: a left-sided crouched juvenile ( 15- 17 y) individual in an oval, NW-SE orientated grave pit 14C dated to 3350-3100 cal. B.C. at 2 sigma (Dani, Ncpper 2006). Neither the burial custom (no ochre strewing or depositing a lump of ochre has been recorded), nor date account for its ascription to the Yamnaya!

All of these tumuli and burials demonstrate, though, that there is already a constant but perhaps low-level 4th millennium cal. B.C. steppe interaction, linking the regions of the north of the Black Sea with those of the west, and reaching deep into the Carpathian basin. This has to be acknowledged. even if these populations remain small, bounded to their steppe habitat with an economy adapted to this special environment, and are not always visible in the record. Indirect hints may help in seeing them, such as the frequent occurrence of horse bones, regarded as deriving from domesticated horses, in Hungarian Baden settlements (Bokonyi 1978; Benecke 1998), and in those of the south German Cham Culture (Matuschik 1999, p. 80-82) and the east German Bernburg Culture (Becker 1999; Benecke 1999). These occur, however, always in low numbers, perhaps not enough to maintain and regenerate a herd. Does this point us towards otherwise archaeologically hidden horsebreeders in the Carpathian basin, before the Yamnaya? In any case, I hope to make one case clear: these are by no means Yamnaya burials in the strict definition! Attribution to the Yamnaya in its strict definition applies.

In Alin Frînculeasa, Bianca Preda, Volker Heyd, Pit-Graves, Yamnaya and Kurgans along the Lower Danube.

Also, about the expansion of Yamna settlers along the steppes:

However, it should have been made clear by the distribution map of the Western Yamnaya that they were confining themselves solely to their own, well-known, steppe habitat and therefore not occupying, or pushing away and expelling, the locally settled farming societies. Also, living solely in the steppes requires another lifestyle, and quite different economic and social bases, most likely very different to the established farming societies. Although surely regarded as incoming strangers, they may therefore not have been seen as direct competitors. This argument can be further enforced when remembering that the lowlands and the steppes in the southeast of Europe had already been populated throughout the 4th millennium cal. B.C., as demonstrated above, by societies with a similar north-Pontic steppe origin and tradition, albeit in lower numbers. It is only for these groups that the Yamnaya may have become a threat, but their common origin and perhaps a similar economic/ social background with comparable lifestyles would surely have assisted to allow rapid assimilation. More important, though, is that farming societies in this region may therefore have been accustomed to dealing and interacting with different people and ethnic strangers for a long time. (…)

When assessing farming and steppe societies’ interaction from a general point of view, attitudes can diverge in three main directions:

  1. the violent one; with raids, fights, struggles, warfare, suppression and finally the superiority and exploitation of the one over the other;
  2. the peaceful one; with a continuous exchange of gifts, goods, work, information and genes in a balanced reciprocal system, leading eventually to the merging of the two societies and creation of a new identity;
  3. the neutral one; with the two societies ignoring each other for a long time.

What we see from trying to understand the record of the Yamnaya, based on their tumuli and burials, and the local and neighbouring contemporary societies, based on their settlements, hoards, and graves, is likely a mixture of all three scenarios, with the balance perhaps more towards exchange in a highly dynamic system with alterations over time. However, violence and raids cannot be ruled out; they would be difficult to see in the archaeological record; or only indirectly, such as the building of hill forts, particularly the defence-like chain of Vucedol hillforts along the south shore of the Danube on the Serbian/Croatian border zone (Tasic 1995a), and the retreat of people into them (Falkenstein 1998, p. 261-262), with other interpretations also possible. And finally, we are dealing here with very different local and neighbouring societies, as well as with more distant contemporary ones, looking, in reality, rather like a chequer board of societies and archaeological cultures (see Parzinger 1993 for the overview). These display different regional backgrounds and traditions leading to different social and settlement organizations, different economic bases and material cultures in the wide areas between Prut and Maritza rivers, and Black Sea and Tisza river. They surely found their individual way of responding to the incoming and settling Yamnaya people.

Yamnaya tumuli signalling the expansion of West Yamna from ca. 3100 BC (especially after ca. 2950 BC). Heyd (2011).

The best data we have about this potential non-Yamna origin of R1b-L51 – and thus in favour of its admixture in the Carpathian basin – lies in:

  1. The majority of R1a-Z2103 subclades found to date among Yamna samples.
  2. The presence of R1b-Z2103 in the Catacomb culture – in the Northern Caucasus and in Ukraine.
  3. The limited presence of (ancient and modern) R1b-L51 in eastern Europe and India, whose isolated finds are commonly (and simplistically) attributed to ‘late migrations’.
  4. The presence of R1b-L51 (xZ2103) in cultures related to the ‘Yamna package’, but supposedly not to Yamna settlers. So for example I7043, of haplogroup R1b-L151(xU106,xP312), ca. 2500-2200 BC from Szigetszentmiklós-Üdülősor, probably from the Bell Beaker (Csepel group), but maybe from the early Nagýrev culture.
  5. The expansion of its subclades apparently only from a single region, around the Carpathian basin, in contrast to R1b-Z2103.
  6. The already ‘diluted’ steppe admixture found in the earliest samples with respect to Yamna, which points to the appearance after the Yamna admixture with the local population.
  7. Ukrainian archaeologists (in contrast to their Russian colleagues) point to the relevance of North Pontic cultures like Kvitjana and Lower Mikhailovka in the development of Early Yamna in the west, and some eastern European researchers also believe in this similarity.
  8. If R1b-Z2103 and R1b-L51 had expanded with Suvorovo-Novodanilovka migrants to the west, and had admixed later as Hungary_LCA-LBA-like peoples with Yamna migrants during the long-term contacts with other ‘kurganized cultures’ ca. 2900-2500 BC in the Great Hungarian Plains, it could explain some peculiar linguistic traits of North-West Indo-European, and also why R1b-Z2103 appears in cultures associated with this earlier ‘steppe influence’ (i.e. not directly related to Yamna) such as Vučedol (with a R1b-Z2103 sample, see below). That could also explain the presence of R1b-L151(xP312, xU106) in similar Balkan cultures, possibly not directly related to Yamna.

A hidden group among north or west Pontic Eneolithic steppe cultures?

The expansion of Khvalynsk as Novodanilovka into the North Pontic area happened through the south across the steppe, near the coast, with the forest-steppe region working as a clear natural border for this culture of likely horse-riding chieftains, whose economy was probably based on some rudimentary form of mobile pastoralism.

Although archaeologists are divided as to the origin of each individual Middle Eneolithic group near the Black Sea after the end of the Khvalynsk-Novodanilovka period, it seems more or less clear that steppe cultures like Cernavodă, Lower Mikhailovka, or Kvitjana are closer (or “more archaic”) in their steppe features, which connects them to Volga–Ural and Northern Caucasus cultures, like Northern Caucasus, Repin or Khvalynsk.

On the other hand, forest-steppe cultures like Dereivka (including Alexandria) show innovative traits and contacts with para- or sub-Neolithic cultures to the north, like Comb-Pit Ware groups, apart from corded decoration influenced by Trypillian groups to the west, especially in their later (‘Proto-Corded Ware‘) stage after ca. 3500 BC.

If Ukrainian researchers like Rassamakin are right, Early Yamna expanded not only from Repin settlers, but also from local steppe cultures adopting Repin traits to develop an Early Yamna culture, similar to how eastern (Volga–Ural groups) seem to have synchronously adopted Early Yamna without massive affluence of Repin settlements.

Furthermore, local traits develop in southern groups, like anthropomorphic stelae (shared with Kemi-Oba, direct heir of Lower Mikhailovka), and rich burials featuring wagons. These traits are seen in west Yamna settlers.

Problems of this model include:

  1. On the North Pontic area – in contrast to the Volga–Ural region – , there was a clear “colonization” wave of Repin settlers, also supported by Ukrainian researchers, based on the number of new settlements and burials, and on the progressive retreat of Dereivka, Kvitjana, as well as (more recent) Maykop- and Trypillia-related groups from the North Pontic area ca. 3350/3300 BC. It seems unlikely that these expansionist, semi-nomadic, cattle-breeding, patrilineally-related steppe clans that were driving all native populations out of their territories suddenly decided, at some point during their spread into the North Pontic area ca. 3300-3100 BC, to join forces with some foreign male lineages from the area, and then continue their expansion to the west…
  2. Similar to the fate of R1b-P297 subclades in the Baltic after the expansion of Corded Ware migrants, previous haplogropus of the North Pontic region – such as R1a, R1b-V88, and I2 subclades basically disappeared from the ancient DNA record after the expansion of Khvalynsk-Novodanilovka, and then after the expansion of Yamna, as is clear from Yamna, Afanasevo, and Bell Beaker samples obtained to date. This, in combination with what we know about Y-chromosome bottlenecks in post-Neolithic expansions, leaves little space to think that a big enough territorial group with a majority of “native” haplogroups could survive later expansions (be it R1b-L51 or R1a-Z645).
  3. Supporting an expansion of the same male (and partly female) population, the Yamna admixture from east to west is quite homogeneous, with the only difference found in (non-significant) EEF-like proportion which becomes elevated in distant areas [apart from significant ‘southern’ contribution to certain outlier samples]. Based on the also homogeneous Y-DNA picture, the heterogeneity must come, in general, from the female exogamy practiced by expanding groups.
  4. There is a short period, spanning some centuries (approximately 3300-2700 BC), in which the North Pontic area – especially the forest-steppe territories to the west of the Dnieper, i.e. the Upper Dniester, Boh, and Prut-Siret areas – are a chaos of incoming and emigrating, expanding and shrinking groups of different cultures, such as late Trypillian groups, Maykop-related traits, TRB, GAC, (Proto-)Corded Ware, and Early Yamna settlements. No natural geographic frontier can be delimited between these groups, which probably interacted in different ways. Nevertheless, based on their cultural traits, admixture, and especially on their Y-DNA, it seems that they never incorporated foreign male lineages, beyond those they probably had during their initial expansion trends.
  5. The further expansionist waves of Early Yamna seen ca. 3100 BC, from the Danube Delta to the west, give an overall image of continuously expanding patrilineal clans of R1b-M269 subclades since the Khvalynsk-Novodanilovka migration, in different periodic steps, mostly from eastern Pontic-Caspian nuclei, usually overriding all encountered cultures and (especially male) populations, rather than showing long-term collaboration and interaction. Such interaction is seen only in exceptional cases, e.g. the long-term admixture between Abashevo and Poltavka, as seen in Proto-Indo-Iranian peoples and their language.

Consequences

We are living right now an exemplary ego-, (ethno-)nationalism-, and/or supremacy-deflating moment, for some individuals of eastern and northern European descent who believed that R1a or ‘steppe ancestry proportions’ meant something special. The same can be said about those who had interiorized some social or ethnolinguistic meaning for the origin of R1b in western Europe, N1c in north-eastern Europe, as well as Greeks, Iranians, Armenians, or Mediterranean peoples in general of ‘Near Eastern’ ancestry or haplogroups, or peoples of Near Eastern origin and/or language.

These people had linked their haplogroups or ancestry with some fantasy continuity of ‘their’ ancestral populations to ‘their’ territories or languages (or both), and all are being proven wrong.

Apart from teaching such people a lesson about what simplistic views are useful for – whether it is based on ABO or RH group, white skin, blond hair, blue eyes, lactase persistence, or on the own ancestry or Y-DNA haplogroup -, it teaches the rest of us what can happen in the near future among western Europeans. Because, until recently, most western Europeans were comfortably settled thinking that our ancestors were some remnant population from an older, Palaeolithic or Mesolithic population, who acquired Indo-European languages by way of cultural diffusion in different periods, including only minor migrations.

Judging by what we can see now among some individuals of Northern and Eastern European descent, the only thing that can worsen the air of superiority among western Europeans is when they realize (within a few years, when all these stupid battles to control the narrative fade) that not only are they the cultural ‘heirs’ of the Graeco-Roman tradition that began with the Roman Empire, but that most of them are the direct patrilineal descendants of Khvalynsk, Yamna, Bell Beaker, and European Bronze Age peoples, and thus direct descendants of Middle PIE, Late PIE, and NWIE speakers.

steppe-chalcolithic-migrations
Steppe-related migrations ca. 3100-2600 BC with tentative linguistic identification.

The finding of R1b-L51 and R1b-Z2103 among expanding Suvorovo-Novodanilovka chieftains, with pockets of R1b-L51 remaining in steppe-like societies of the Balkans and the Carpathian Basin, would have beautifully complemented what we know about the East Yamna admixture with R1a-Z93 subclades (Uralic speakers) ca. 2600-2100 BC to form Proto-Indo-Iranian, and about the regional admixtures seen in the Balkans, e.g. in Proto-Greeks, with the prevalent J subclades of the region.

It would have meant an end to any modern culture or nation identifying themselves with the ‘true’ Late PIE and Yamna heirs, because these would be exclusively associated with the expansion of R1b-Z2103 subclades with late Repin, and later as the full-fledged Late PIE with Yamna settlers to south-east and central Europe, and to the southern Urals. The language would have had then obviously undergone different language changes in all these territories through long-lasting admixture with other populations. In that sense, it would have ended with the ideas of supremacy in western Europe before they even begin.

The most likely future

However limited the evidence, it seems that R1b-L51 expanded with Yamna, though, based on the estimates for the haplogroups involved, and on marginal hints at the variability of L23 subclades within Yamna and neighbouring populations. If R1b-L51 expanded with West Repin / Early Yamna settlers, this is why they have not yet been found among Yamna samples:

steppe-eneolithic-migrations
Simplified map of Repin expansions from ca. 3500/3400 BC.
  • The subclade division of Yamna settlers needs not be 50:50 for L51:Z2103, either in time or in space. I think this is the simplistic view underlying many thoughts on this matter. Many different expanding patrilineal clans of L23 subclades may have been more or less successful in different areas, and non-Z2103 may have been on the minority, or more isolated relative to Z2103-clans among expanding peoples on the steppe, especially on the east. In fact, we usually talk in terms of “Z2103 vs. L51” as if
    1. these two were the only L23 subclades; and
    2. both had split and succeeded (expanding) synchronously;

    that is, as if there had not been multiple subclades of both haplogroups, and as if there had not been different expansion waves for hundreds of years stemming from different evolving nuclei, involving each time only limited (successful) clans. Many different subclades of haplogroups L23 (xZ2103, xL51), Z2103, and L51 must have been unsuccessful during the ca. 1,500 years of late Khvalynsk and late Repin-Early Yamna expansions in which they must have participated (for approximately 60-75 generations, based on a mean 20-25 years).

  • If we want to imagine a pocket of ‘hidden’ L51 for some region of the North Pontic or Carpathian region, the same can be imagined – and much more likely – for any unsampled territory of expanding late Repin/Early Yamna settlers from the Lower Don – Lower Volga region (probably already a mixed society of L51 and Z2103 subclades since their beginning, as the early Repin culture, ca. 3800 BC), with L51 clans being probably successful to the west.
  • The Repin culture expanded only in small, mobile settlements from the Lower Don – Lower Volga to the north, east, and south, starting ca. 3500/3400 BC, in the waves that eventually gave a rather early distant offshoot in the Altai region, i.e. Afanasevo. Starting ca. 3300 BC in the archaeological record, the majority of R1b-Z2103 subclades found to date in Afanasevo also supports either
    • a mixed Repin society, with Z2103-clans predominating among eastern settlers; or
    • a Repin society marked by haplogroup L51, and thus a cultural diffusion of late Repin/Early Yamna traits among neighbouring (Khvalynsk, Samara, etc.) groups of essentially the same (early Khvalynsk-Novodanilovka) genetic stock in the Volga–Ural region.

    Both options could justify a majority of Z2103 in the Lower Volga–Ural region, with the latter being supported by the scattered archaeological remains of late Repin in the region before the synchronous emergence of Early Yamna findings in the whole Pontic-Caspian steppe.

  • Most Z2103 from Yamna samples to date are from around 3100 BC (in average) onward, and from the right bank of the Lower Don to the east, particularly from the Lower Volga–Ural area (especially the Samara region), which – based on the center of expansion of late Repin settlers – may be depicting an artificially high Z2103-distribution of the whole Yamna community.

Repin expansion into the Volga–Ural region from ca. 3500/3400 BC. Map made by me based on maps and data from Morgunova (2014, 2016). Lopatino is marked with number 64.
  • Yamna sample I0443, R1b-L23 (Y410+, L51-), ca. 3300-2700 BCE from Lopatino II, points to an intermediate subclade between L23 and L51, near one of the supposed late Repin sites (based on kurgan burials with late Repin cultural traits) in the Samara region.
  • Other Balkan cultures potentially unrelated to the Yamna expansion also show Z2103 (and not only L51) subclades, like I3499 (ca. 2884-2666 calBC), of the Vučedol culture, from Beli Manastir-Popova zemlja, which points to the infiltration of Yamna peoples in other cultures. In any case, the appearance of R1b-L23 subclades in the region happens only after the Yamna expansion ca. 3100 BC, probably through intrusions into different neighbouring regions, if these Balkan cultures are not directly derived from Yamna settlements (which is probably the case of the Csepel Bell Beaker or early Nagýrev sample, see above).
  • The diversity of haplogroups found in or around the Carpathian Basin in Late Chalcolithic / Early Bronze Age samples, including L151(xP312, xU106), P312, U106, Z2103, makes it the most likely sink of Yamna settlers, who spread thus with expanding family clans of different R1b-L23 subclades.
  • Even though some Yamna vanguard groups are known to have expanded up to Saxony-Anhalt before ca. 2700 BC, haplogroup Z2103 seems to be restricted to more eastern regions, which suggests that R1b-L51 was already successful among expanding West Yamna clans in Hungary, which gave rise only later to expanding East Bell Beakers (overwhelmingly of L151 subclades). The source of R1b-L51 and L151 expansion over Z2103 must lie therefore in the West Yamna period, and not in the Bell Beaker expansion.

Yamna migrants ca. 3300-2600. Most likely site of admixture with GAC circled in red.
  • The R1b-Z2103 found in Poltavka, Catacomb, and to the south point to a late migration displacing the western R1b-L51, only after the late Repin expansion. This is also seen in the steppe ancestry and R1b-Z2103 south of the Caucasus, in Hajji Firuz, which points to this route as a potential source of the supposed “Earliest Proto-Indo-Iranian” (the mariannu term) of the Near East. A similar replacement event happened some centuries later with expanding R1a-Z93 subclades from the east wiping out haplogroup R1b-Z2103 from the Pontic-Caspian steppe.
  • Many ancient samples from Khvalynsk, Northern Caucasus, Yamna, or later ones are reported simply as R1b-M269 or L23, without a clear subclade, so the simplistic ‘Yamna–Z2103’ picture is not real: if one takes into account that Z2103 might have been successful quite early in the eastern region, it is more likely to obtain a successful Y-SNP call of a Z2103 subclade in the Volga–Ural region than a xZ2103 one.
  • There are some modern samples of R1b-L51 in eastern Europe and Asia, whose common simplistic attribution to “late expansions” is usually not substantiated; and also ancient R1b-L51 samples might be confirmed soon for Asia.
  • ‘Western’ features described by archaeologists for West Yamna settlers, associated with Kemi Oba and southern Yamna groups in the North Pontic area – like rich burials with anthropomorphic stelae and wagons – are actually absent in burials from settlers beyond Bulgaria, which does not support their affiliation with these local steppe groups of the Black Sea. Also, a mix with local traditions is seen accross all Early Yamna groups of the Pontic-Caspian steppe, and still genetics and common cultural traits point to their homogeneization under the same patrilineal clans expanding continuously for centuries. The maintenance of local traditions (as evidenced by East Bell Beakers in Iberia related to Iberian Proto-Beakers) is often not a useful argument in genetics, especially when the female population is not replaced.

Conclusion

This is what we know, using linguistics, archaeology, and genetics:

  • Middle Proto-Indo-European expanded with Khvalynsk-Novodanilovka after ca. 4800 BC, with the first Suvorovo settlements dated ca. 4600 BC.
  • Archaic Late Proto-Indo-European expanded with late Repin (or Volga–Ural settlers related to Khvalynsk, influenced by the Repin expansion) into Afanasevo ca. 3500/3400 BC.
  • Late Proto-Indo-European expanded with Early Yamna settlers to the west into central Europe and the Balkans ca. 3100 BC; and also to the east (as Pre-Proto-Indo-Iranian) into the southern Urals ca. 2600 BC.
  • North-West Indo-European expanded with Yamna Hungary -> East Bell Beakers, from ca. 2500 BC.
  • Proto-Indo-Iranian expanded with Sintashta, Potapovka, and later Andronovo and Srubna from ca. 2100 BC.

It seems that the subclades from Khvalynsk ca. 4250-4000 BC were wrongly reported – like those of Narasimhan et al. (2018). However, even if they are real and YFull estimates have to be revised, and even if the split had happened before the expansion of Suvorovo-Novodanilovka, the most likely origin of R1b-L51 among Bell Beakers will still be the expansion of late Repin / Early Yamna settlers, and that is what ancient DNA samples will most likely show, whatever the social or political consequences.

The only relevance of the finding of R1b-L51 in one place or another – especially if it is found to be a remnant of a Middle PIE expansion coupled with centuries of admixture and interaction in the Carpathian Basin – is the potential influence of an archaic PIE (or non-IE) layer on the development of North-West Indo-European in Yamna Hungary -> East Bell Beaker. That is, more or less like the Uralic influence related to the appearance of R1a-Z93 among Proto-Indo-Iranians, of R1a-Z284 among Pre-Germanic peoples, and of R1a-Z282 among Balto-Slavic peoples.

I think there is little that ancient DNA samples from West Yamna could add to what we know in general terms of archaeology or linguistics at this point regarding Late PIE migrations, beyond many interesting details. I am sure that those who have not attributed some random 6,000-year-old paternal ancestor any magical (ethnic or nationalist) meaning are just having fun, enjoying more and more the precise data we have now on European prehistoric populations.

As for those who believe in magical consequences of genetic studies, I don’t think there is anything for them to this quest beyond the artificially created grand-daddy issues. And, funnily enough, those who played (and play) the ‘neutrality’ card to feel superior in front of others – the “I only care about the truth”-type of lie, while secretly longing for grandpa’s ethnolinguistic continuity – are suffering the hardest fall.

Copenhagen group: Germanic and Balto-Slavic from Bell Beaker; Indo-Anatolian homeland in the Caucasus

invasion-from-the-steppe-yamnaya

Article of general knowledge in Der Spiegel, Invasion from the Steppe, with comments from Willerslev and Kristiansen, appeared roughly at the same time as the Damgaard et al. Nature (2018) and Science (2018) papers were published.

NOTE. You can read the article (in German) from Kristiansen’s Academia.edu account.

Excerpts translated from German (emphasis mine):

On the Y-DNA data

Particularly striking is the genetic signature from the steppe on the Y chromosome. From this the researchers conclude that the majority of migrants were males. Kristian Kristiansen, chief archaeologist in the Willerslev team, also has an idea of ​​how this could be explained: “Maybe it’s a rite of initiation, as it was spread among the steppe peoples,” he says.

The younger sons of the Yamnaya herders, who were excluded from the succession, had to seek their fortune on their own. As part of a solemn ritual, they threw themselves to wolves’ skins and then swarmed in warlike gangs to buy their own herds by cattle-stealing.

(…)

An ally that they seem to have brought from their homeland may also have contributed to the genetic success of the steppe people: Yersinia pestis, the plague bacterium. Its genes were found by researchers from the Max Planck Institute in Jena – and apparently it emerged exactly at the same time as the Yamnaya thrust began.

About the Hittites

(…) And yet now, where Asia and Europe meet geographically, there is no trace of the Yamnaya genes. The wander-loving people from the Pontic-Caspian steppe apparently found neither the way across the Balkans nor through the Caucasus mountains.

Now the researchers are puzzled: How can it be that a language goes on a walk, without the accompanying speakers coming along? Is it possible that the Indo-European seeped into Anatolia, much like the English language spread today without the need for Englishmen?

Archaeologist Kristiansen does not believe it. The researchers would find it hard to reconsider their theories, he says: “Especially the first chapter of the story has to be rewritten.”

He suspects that there was a predecessor of the Yamnaya culture, in which a kind of Proto-Proto-Indo-European was spoken. And he also has a suspicion, where this people could have drifted around: The Caucasus, says Kristiansen, was their homeland. But that remains unproven: “There’s another hole left,” he admits.

invasion-yamnaya-steppe
Spread of Indo-European languages

About the Botai

The study of [the Botai] genome revealed that it was genetically radically different from the members of the Yamnaya culture. The Botai, it seems, consistently avoided any contact with their neighbors – even though they must have crossed the territory of the Botai on their migratory waves.

Willerslev assumes that the art of keeping horses from the Yamnaya steppe nomads was adopted from these peoples, and then they developed it further. At some point, the Botai could then have itself become doomed by its groundbreaking innovation: While the descendants of the Yamnaya spread over half of Eurasia, the Botai disappeared without leaving a trace.

Even more interesting than the few words that set the Copenhagen group’s views for future papers (such as the expected Maykop samples with EHG ancestry) is the artistic sketch of the Indo-European migrations, probably advised by the group.

A simple map does not mean that all members of the Danish workgroup have changed their view completely, but I would say it is a great improvement over the previous “arrows of migration” (see here), and it is especially important that they show a more realistic picture of ancient migrations to general readers.

NOTE. Especially absurd is the identification of the ‘Celtic’ expansion with the first Bell Beakers in the British Isles (that idea is hold by few, such as Koch and Cunliffe in their “Celtic from the West” series). Also inexact, but not so worrying, are the identification of ‘Germanic’ in Germany/Únětice, or the spread of ‘Baltic’ and ‘Slavic’ directly to East Europe (i.e. I guess Mierzanowice/Nitra -> Trzciniec), which is probably driven by the need to assert a close connection with early Iranians and thus with their satemization trends.

Also, as we know now thanks to Narasimhan et al. (2018), there is no need to support that convoluted west arrow (representing CWC) from West Yamna to Central Europe, and then to East Yamna, since the Proto-Indo-Iranian community – represented by the Steppe MLBA cloud that later expanded Indo-Aryan and Iranian languages – has a more direct connection with the in situ admixture of Poltavka/Abashevo within the Volga-Ural region.

I think we can keep this from the article:

Their results, as well as those of the competition labs at Harvard University and Jena’s Max Planck Institute for the History of Humanity, leave no doubt: Yes, the legendary herdsmen in the Pontic-Caspian steppe really existed. They belonged to the so-called Yamnaya culture, and they spread, as linguists had predicted, in massive migrations towards Central Europe and India – a later triumph for linguists.

This can be added to a recent comment by de Barros Damgaard:

The project has been an extremely enriching and exciting process. We were able to direct many very different academic fields towards a single coherent approach. By asking the right questions, and keeping limitations of the data in mind, contextualizing, nuancing, and keeping dialogues open between scholars of radically different backgrounds and approaches, we have carved out a path for a new field of research. We have already seen too many papers come out in which models produced by geneticists working on their own have been accepted without vital input from other fields, and, at the other extreme, seen archaeologists opposing new studies built on archaeogenetic data, due to a lack of transparency between the fields.

Data on ancient DNA is astonishing for its ability to provide a fine-grained image of early human mobility, but it does stand on the shoulders of decades of work by scholars in other fields, from the time of excavation of human skeletons to interpreting the cultural, linguistic origins of the samples. This is how cold statistics are turned into history.

Consequences of Damgaard et al. 2018 (III): Proto-Finno-Ugric & Proto-Indo-Iranian in the North Caspian region

copper-age-early_yamna-corded-ware

The Indo-Iranian – Finno-Ugric connection

On the linguistic aspect, this is what the Copenhagen group had to say (in the linguistic supplement) based on Kuz’mina (2001):

(…) a northern connection is suggested by contacts between the Indo-Iranian and the Finno-Ugric languages. Speakers of the Finno-Ugric family, whose antecedent is commonly sought in the vicinity of the Ural Mountains, followed an east-to-west trajectory through the forest zone north and directly adjacent to the steppes, producing languages across to the Baltic Sea. In the languages that split off along this trajectory, loanwords from various stages in the development of the Indo-Iranian languages can be distinguished: 1) Pre-Proto-Indo-Iranian (Proto-Finno-Ugric *kekrä (cycle), *kesträ (spindle), and *-teksä (ten) are borrowed from early preforms of Sanskrit cakrá- (wheel, cycle), cattra- (spindle), and daśa- (10); Koivulehto 2001), 2) Proto-Indo-Iranian (Proto-Finno-Ugric *śata (one hundred) is borrowed from a form close to Sanskrit śatám (one hundred), 3) Pre-Proto-Indo-Aryan (Proto-Finno-Ugric *ora (awl), *reśmä (rope), and *ant- (young grass) are borrowed from preforms of Sanskrit ā́rā- (awl), raśmí- (rein), and ándhas- (grass); Koivulehto 2001: 250; Lubotsky 2001: 308), and 4) loanwords from later stages of Iranian (Koivulehto 2001; Korenchy 1972). The period of prehistoric language contact with Finno-Ugric thus covers the entire evolution of Pre-Proto-Indo-Iranian into Proto-Indo-Iranian, as well as the dissolution of the latter into Proto-Indo- Aryan and Proto-Iranian. As such, it situates the prehistoric location of the Indo-Iranian branch around the southern Urals (Kuz’mina 2001).

NOTE. While I agree with the evident ancestral nature of the *kekrä borrowing, I will repeat it here again: I don’t believe that the distinction of late Proto-Indo-Iranian from ‘Pre-Proto-Indo-Aryan’ loans is warranted; not for words reconstructed from recent Finno-Ugric languages.

copper-age-late-urals
The time and place for Finno-Ugric and Indo-Iranian contacts. Late Copper Age migrations in Asia ca. 2800-2300 BC.

In this period of a Pre-Proto-Indo-Iranian community, which is to be associated with East Yamna/Poltavka, ca. 3000-2400 BC – as accepted in the supplement from de Barros Damgaard et al. (Nature 2018) – , both Poltavka and Abashevo/Balanovo herders were expanding ca. 2800-2600 BC to the east (and Abashevo already admixing into Poltavka territory), near the southern Urals.

There is no other, clearer, later connection between Finno-Ugric and Proto-Indo-Iranian speakers. Even the arrival of the Seima-Turbino phenomenon (after ca. 2000 BC), if it brought migrants to North-East Europe, would not fit the linguistic, archaeological, or genetic data. It is by now quite clear that Seima-Turbino does not fit with incoming N1c1 lineages and/or Siberian ancestry, either, for those looking for these as potential signs of incoming Uralic speakers.

While the Copenhagen group did not have access to data from Sintashta ca. 2100 BC onwards – now available in Narasimhan et al. (2018) – when submitting the papers, we already know that there was a clear long period of slow progressive admixture in the North Caspian region. It can be seen in the genetic contribution of Yamna to incoming Abashevo groups, and in the R1b-L23 samples still appearing in Sintashta until ca. 1800 BC (as I predicted could happen).

Since the first sample signalling incoming Abashevo migrants is found in the Poltavka outlier dated ca. 2700 BC (of R1a-Z93 lineage), this represents a rather unique, several centuries long process of admixture in the North Caspian region, different from the massive Afanasevo or Bell Beaker migrations in Asia and Europe, whereby a great part of the native male population was suddenly replaced.

This offers further support for language continuity despite genetic replacement in the development of East Yamna/Poltavka (part of the Steppe EMBA cline, formed by Yamna and Afanasevo) mixing with Abashevo migrants (probably identical to Corded Ware samples) to form Potapovka, Sintashta, and later Srubna, and Andronovo communities (all forming, with Corded Ware groups, a wide Eurasian Steppe MLBA cloud). See the available data from Narasimhan et al. (2018).

yamna-late-proto-indo-european
Image modified from Narasimhan et al. (2018), including the most likely proto-language identification of different groups. Original description “Modeling results including Admixture events, with clines or 2-way mixtures shown in rectangles, and clouds or 3-way mixtures shown in ellipses”. See the original full image here.

The continuous interactions and migrations left thus eventually two communities in the southern Urals genetically similar, but ethnolinguistically diverse:

  • To the north, Abashevo-Balanovo – but potentially also Fatyanovo, and related North-East European late Corded Ware groups – borrowed necessary words from Indo-Iranian neighbours, while maintaining their Finno-Ugric language and culture.
  • To the south, immigrants (or their descendants) of Abashevo origin expanding among Pre-Proto-Indo-Iranian-speaking North Caspian communities assimilated the surrounding culture and language, giving it their own accent (i.e. ‘satemizing’ it) and turning it into Proto-Indo-Iranian (see e.g. Parpola’s account).

Anthropologically, this ‘long-term founder effect’ that appears as genetic replacement is probably explained by the faster life history in MLBA North Caspian populations, likely due to a combination of changing environmental and social circumstances.

NOTE. The prevalent explanation before the latest studies on the Sintashta society were social strife and isolation of small groups, an argument I used in my demic diffusion model. Other, similar cases of proven linguistic continuity despite genetic replacement are seen in Iberian Bronze Age after the expansion of R1b-L23 lineages (with Vasconic, Iberian, and Tartessian surviving at least until proto-historic times), and in Remote Oceania.

Diachronic map of migrations in Asia ca. 2250-1750 BC

Implications for Late PIE migrations

I am happy to see that people are resorting now to dialectal classifications and Y-DNA to explain the findings in Old Hittites, Tocharians (and related migrations), and Indo-Iranians. It is especially interesting to see precisely this Danish group downplay the relevance of ancestry and favor complex anthropological models when assessing migrations and ethnolinguistic identification.

So let’s talk about the growing elephant in the room.

It seems we all accept now Tocharian’s more archaic Late PIE nature, which is supported by waves of late Khvalynsk migrants starting probably ca. 3300 BC, as seen in different samples to the east in Central Asia, and to the south in Iran. Almost all of them share R1b-L23 lineages.

NOTE. Whereas their early LPIE dialects have not survived to historic times, the rather speculative hypotheses of Euphratic and Gutian languages may be of interest.

We also know of the coetaneous migrants that settled to the west of the Don River (in the territory of the previous late Sredni Stog culture), to form the western South-Bug / Lower Don groups, which, together with the Volga-Ural / North Caucasian groups formed the early Yamna culture, that dominated from ca. 3300 BC over the Pontic-Caspian steppe.

It is only logical that the other attested languages belonging to the common Late PIE trunk must come from these groups, which must have stuck together for quite some time – after the recently proven late Khvalynsk migrations – , to allow for the spread of isoglosses (not found in Tocharian) among them.

This is agreed, even by the Copenhagen group, who expressly state that Yamna is to be identified with the rest of Late PIE languages after the Tocharian-related migrations.

copper-age-early_yamna-corded-ware
Early Yamna community and its migrations ca. 3000 BC onwards.

The period of an early Yamna community constrained to the Pontic-Caspian steppe (ca. 3300-3000 BC) is followed by renewed waves of Late Proto-Indo-European migrations, during which areal contacts and innovations (even between unrelated LPIE branches) can still be reconstructed.

These later migrations can be precisely described as follows (after the latest studies):

  • Yamna migrants, of mixed R1b-L51 and R1b-Z2103 lineages, settle ca. 3000-2600 BC along the lower Danube, in the Balkans and the Carpathian basin, giving rise later to groups of:
  • In the Pontic-Caspian steppe, early Yamna groups evolve into (from west to east) Late Yamna, Catacomb, and Poltavka groups, ca. 2800-2300 BC, all still dominated by R1b-L23 lineages (see discussion on the Catacomb sample), with:
    • Poltavka peoples admixing with Abashevo migrants to form admixed Potapovka and Sintashta-Petrovka groups, showing still after ca. 1800 BC a mixed society of R1a-Z93 and R1b-Z2103 lineages (see Narasimhan et al. 2018);
      • Expanding early Proto-Iranian and Proto-Indo-Aryan groups in Srubna (to the west) and Andronovo (to the east), during the first half of the 2nd millennium BC, dominate over the Bronze Age steppe and Central Asia with expanding R1a-Z93 lineages.

Conclusion

chalcolithic_late_Europe_Bell_Beaker
Diachronic map of Late Copper Age migrations including Classical Bell Beaker (east group) expansion from central Europe ca. 2600-2250 BC

1) East Bell Beakers clearly dominated culturally and genetically over almost all of Europe, ca. 2500-2000 BC, including previous Corded Ware territory, representing thus the most recent massive migration of steppe peoples in Europe, and being the only pan-European culture derived from Late Proto-Indo-European-speaking Yamna. They must therefore be identified with North-West Indo-European speakers, as proposed by Mallory (2013), and not just Italo-Celtic (as supported recently by the Danish school, based on Gimbutas’ outdated model):

1.A) For Germanic, we already have proof that an appropriate, unitary Scandinavian society, ripe for the development of a common Pre-Germanic language (that expanded much later, during the Iron Age, as Proto-Germanic) could have developed only after the arrival of Bell Beakers (see Prescott 2017). The association of proto-historic Germanic tribes mainly with the expansion of R1b-U106 lineages bears witness to that.

NOTE. Even without taking into account the likely L51 samples from Khvalynsk, it is by now quite clear that R1b-L51 lineages were already admixed in Yamna settlers from the Carpathian Basin, and any subclade of U106, L21, DF27, or U152 can thus be found everywhere in Europe associated with any of those North-West Indo-European migrations. What we are seing later, as in the East Bell Beaker migrants arriving in the British Isles (L21), Iberia (DF27), or the Netherlands/Scandinavia (U106), is the further reduction in variability coupled with the expansion of a few sucessful families (and their lineages), as we know it usually happens during migrations.

1.B) For Balto-Slavic, it seems they were not part of the eastern Corded Ware peoples: the Copenhagen group denies an Indo-Slavonic group in the Nature paper, referring instead to a dominion of early Iranians in the steppes, following their traces to proto-historic and historic Iranian-speaking peoples. And we knew already that Bell Beakers dominated over Central-East Europe, before the resurge of R1a-Z645 lineages in the region, which is compatible with the North-West Indo-European nature of their language undergoing a satemization process similar (but not equal to) to the Indo-Iranian one (see the full discussion on Balto-Slavic here).

NOTE. The few ancestral traits common to Germanic and Balto-Slavic are today considered a common substrate language to both, and not due to close contacts (and still less a common branch, as was proposed in the 1st half of the 20th c.). You can read e.g. Kortlandt’s Baltic, Slavic, Germanic (2017), or our Corded Ware substrate hypothesis (2017). In both theories, the referenced substrate is likely a non-Indo-European language, and in both cases it is related to the Corded Ware culture, which represents their most common immediate ancestral population before the spread of Bell Beakers.

2) The late Corded Ware groups of Finland and Estonia, as well as Fatyanovo and Abashevo (and succeeding groups of Eastern Europe) may now be more clearly associated with Proto-Finno-Ugric dialects, and thus probably Corded Ware groups in general with Uralic languages, whose western branches have not survived to this day, with their culture and language being replaced quite early by expanding Bell Beakers.

NOTE. While the demise of Central and Central-East European CWC groups is evident, continuous contacts among Battle Axe culture groups in Scandinavia and the Gulf of Finland through the Baltic Sea – and the strong Bronze Age Palaeo-Germanic influence on Finnic languages (stronger than earlier Indo-Iranian borrowings) may point to the continuity of Proto-Finnic in Northern Scandinavia, which may force a reinterpretation of the prehistoric location of Proto-Finnic-speaking groups.

Those supporting a Corded Ware expansion of Germanic or Balto-Slavic with R1a subclades, now rejecting the expansion of Proto-Indo-European from an Anatolian homeland (following the spread of Neolithic farmer ancestry), and negating the close Proto-Indo-Iranian – Uralic contacts, are willfully ignoring linguistic, archaeological, and genetic data whenever it does not fit with their previous theories.

Good times ahead to chase false syllogisms and contradictions everywhere.

Consequences of Damgaard et al. 2018 (II): The late Khvalynsk migration waves with R1b-L23 lineages

chalcolithic_early-asia

This post should probably read “Consequences of Narasimhan et al. (2018),” too, since there seems to be enough data and materials published by the Copenhagen group in Nature and Science to make a proper interpretation of the data that will appear in their corrected tables.

The finding of late Khvalynsk/early Yamna migrations, identified with early LPIE migrants almost exclusively of R1b-L23 subclades is probably one of the most interesting findings in the recent papers regarding the Indo-European question.

Although there are still few samples to derive fully-fledged theories, they begin to depict a clearer idea of waves that shaped the expansion of Late Proto-Indo-European migrants in Eurasia during the 4th millennium BC, i.e. well before the expansion of North-West Indo-European, Palaeo-Balkan, and Indo-Iranian languages.

Late Khvalynsk expansions and archaic Late PIE

Like Anatolian, Tocharian has been described as having a more archaic nature than the rest of Late PIE. However, Pre-Tocharian belongs to the Late PIE trunk, clearly distinguishable phonetically and morphologically from Anatolian.

It is especially remarkable that – even though it expanded into Asia – it has more in common with North-West Indo-European, hence its classification (together with NWIE) as part of a Northern group, unrelated to Graeco-Aryan.

The linguistic supplement by Kroonen et al. accepts that peoples from the Afanasevo culture (ca. 3000-2500 BC) are the most likely ancestors of Tocharians.

NOTE. For those equating the Tarim Mummies (of R1a-Z93 lineages) with Tocharians, you have this assertion from the linguistic supplement, which I support:

An intermediate stage has been sought in the oldest so-called Tarim Mummies, which date to ca. 1800 BCE (Mallory and Mair 2000; Wáng 1999). However, also the language(s) spoken by the people(s) who buried the Tarim Mummies remain unknown, and any connection between them and the Afanasievo culture on the one hand or the historical speakers of Tocharian on the other has yet to be demonstrated (cf. also Mallory 2015; Peyrot 2017).

New samples of late Khvalynsk origin

These are are the recent samples that could, with more or less certainty, correspond to migration waves from late Khvalynsk (or early Yamna), from oldest to most recent:

  • The Namazga III samples from the Late Eneolithic period (in Turkmenistan), dated ca. 3360-3000 BC (one of haplogroup J), potentially showing the first wave of EHG-related steppe ancestry into South Asia. Not related to Indo-Iranian migrations.

NOTE. A proper evaluation with further samples from Narasimhan et al. (2018) is necessary, though, before we can assert a late Khvalynsk origin of this ancestry.

  • Afanasevo samples, dated ca. 3081-2450 BC, with all samples dated before ca. 2700 BC uniformly of R1b-Z2103 subclades, sharing a common genetic cluster with Yamna, showing together the most likely genomic picture of late Khvalynsk peoples.

NOTE 1. Anthony (2007) put this expansion from Repin ca. 3300-3000 BC, while his most recent review (2015) of his own work put its completion ca. 3000-2800. While the migration into Afanasevo may have lasted some time, the wave of migrants (based on the most recent radiocarbon dates) must be set at least before ca. 3100 BC from Khvalynsk.

NOTE 2. I proposed that we could find R1b-L51 in Afanasevo, presupposing the development of R1b-L51 and R1b-Z2103 lineages with separating clans, and thus with dialectal divisions. While finding this is still possible within Khvalynsk regions, it seems we will have a division of these lineages already ca. 4250-4000 BC, which would require a closer follow-up of the different inner late Khvalynsk groups and their samples. For the moment, we don’t have a clear connection through lineages between North-West Indo-European groups and Tocharian.

tocharian-early-copper-age
Early Copper Age migrations in Asia ca. 3300-2800, according to Anthony (2015).
  • Subsequent and similar migration waves are probably to be suggested from the new sample of Karagash, beyond the Urals (attributed to the Yamna culture, hence maintaining cultural contacts after the migration waves), of R1b-Z2103 subclade, ca. 3018-2887 BC, potentially connected then to the event that caused the expansion of Yamna migrants westward into the Carpathians at the same time. Not related to Indo-Iranian migrations.
  • The isolated Darra-e Kur sample, without cultural adscription, ca. 2655 BC, of R1b-L151 lineage. Not related to Indo-Iranian migrations.
  • The Hajji Firuz samples: I4243 dated ca. 2326 BC, female, with a clear inflow of steppe ancestry; and I2327 (probably to be dated to the late 3rd millennium BC or after that), of R1b-Z2103 lineage. Not related to Indo-Iranian migrations.

NOTE. A new radiocarbon dating of I2327 is expected, to correct the currently available date of 5900-5000 BC. Since it clusters nearer to Chalcolithic samples from the site than I4243 (from the same archaeological site), it is possible that both are part of similar groups receiving admixture around this period, or maybe I2327 is from a later period, coinciding with the Iron Age sample F38 from Iran (Broushaki et al. 2016), with which it closely clusters. Also, the finding of EHG-related ancestry in Maykop samples dated ca. 3700-3000 BC (maybe with R1b-L23 subclades) offers another potential source of migrants for this Iranian group.

NOTE. Samples from Narasimhan et al. (2018) still need to be published in corrected tables, which may change the actual subclades shown here.

These late Khvalynsk / early Yamna migration waves into Asia are quite early compared to the Indo-Iranian migrations, whose ancestors can only be first identified with Volga-Ural groups of Yamna/Poltavka (ca. 3000-2400 BC), with its fully formed language expanding only with MLBA waves ca. 2300-1200 BC, after mixing with incoming Abashevo migrants.

While the authors apparently forget to reference the previous linguistic theories whereby Tocharian is more archaic than the rest of Late PIE dialects, they refer to the ca. 1,000-year gap between Pre-Tocharian and Proto-Indo-Iranian migrations, and thus their obvious difference:

The fact that Tocharian is so different from the Indo-Iranian languages can only be explained by assuming an extensive period of linguistic separation.

Potential linguistic substrates in the Middle East

A few words about relevant substrate language proposals.

Euphratic language

What Gordon Whittaker proposes is a North-West Indo-European-related substratum in Sumerian language and texts ca. 3500 BC, which may explain some non-Sumerian, non-Semitic word forms. It is just one of many theories concerning this substratum.

eneolithic_steppe
Diachronic map of Eneolithic migrations ca. 4000-3100 BC

This is a summary of his findings from his latest writing on the subject (a chapter of a book on Indo-European phonetics, from the series Copenhagen Studies in Indo-European):

In Sumerian and Akkadian vocabulary, the cuneiform writing system, and the names of deities and places in Southern Mesopotamia a body of lexical material has been preserved that strongly suggests influence emanating from a superstrate of Indo-European origin. his Indo-European language, which has been given the name Euphratic, is, at present, attested only indirectly through the filters of Sumerian and Akkadian. The attestations consist of words and names recorded from the mid-4th millennium BC (Late Uruk period) onwards in texts and lexical lists. In addition, basic signs that originally had a recognizable pictorial structure in proto-cuneiform preserve (at least from the early 3rd millennium on) a number of phonetic values with no known motivation in Sumerian lexemes related semantically to the items depicted. This suggests that such values are relics from the original logographic values for the items depicted and, thus, that they were inherited from a language intimately associated with the development of writing in Mesopotamia. Since specialists working on proto-cuneiform, most notably Robert K. Englund of the Cuneiform Digital Library Initiative, see little or no evidence for the presence of Sumerian in the corpus of archaic tablets, the proposed Indo-European language provides a potential solution to this problem. It has been argued that this language, Euphratic, had a profound influence on Sumerian, not unlike that exerted by Sumerian and Akkadian on each other, and that the writing system was the primary vehicle of this influence. he phonological sketch drawn up here is an attempt to chart the salient characteristics of this influence, by comparing reconstructed Indo-European lexemes with similarly patterned ones in Sumerian (and, to a lesser extent, in Akkadian).

His original model, based on phonetic values in basic proto-cuneiform signs, is quite imaginative and a very interesting read, if you have the time. His Academia.edu account hosts most of his papers on the subject.

We could speculate about the potential expansion of this substrate language with the commercial contacts between Uruk and Maykop (as I did), now probably more strongly supported because of the EHG found in Maykop samples.

NOTE. We could also put it in relation with the Anatolian language of Mari, but this would require a new reassessment of its North-West Indo-European nature.

Nevertheless, this theory is far from being mainstream, anywhere. At least today.

NOTE. The proposal remains still hypothetic, because of the flaws in the Indo-European parallels – similar to Koch’s proposal of Indo-European in Tartessian inscriptions. A comprehensive critic approach to the theory is found in Sylvie Vanséveren’s A “new” ancient Indo-European language? On assumed linguistic contacts between Sumerian and Indo-European “Euphratic”, in JIES (2008) 36:3&4.

Gutian language

References to Gutian are popping up related to the Hajji Firuz samples of the mid-3rd millennium.

The hypothesis was put forward by Henning (1978) in purely archaeological terms.

This is the relevant excerpt from the book:

(…) Comparativists have asserted that, in spite of its late appearance, Tokharian is a relatively archaic form of Indo-European.3 This claim implies that the speakers of this group separated from their Indo-European brethren at a comparatively early date. They should accordingly have set out on their migrations rather early, and should have appeared within the Babylonian sphere of influence also rather early. Earlier, at any rate, than the Indo-Iranians, who spoke a highly developed (therefore probably later) form of Indo-European. Moreover, as some of the Indo-Iranians after their division into Iranians and Indo-Aryans4 appeared in Mesopotamia about 1500 B.C., we should expect the Proto-Tokharians about 2000 B.C. or even earlier.

If, armed with these assumptions as our working hypothesis, we look through the pages of history, we find one nation – one nation only – that perfectly fulfills all three conditions, which, therefore, entitles us to recognize it as the “Proto-Tokharians”. Tis name was Guti; the intial is also spelled with q (a voiceless back velar or pharyngeal), but the spelling with g is the original one. The closing -i is part of the name, for the Akkadian case-endings are added to it, nom. Gutium etc. Guti (or Gutium, as some scholars prefer) was valid for the nation, considered as an entity, but also for the territory it occupied.
(…).

The text goes on to follow the invasion of Babylonia by the Guti, and further eastward expansions supposedly connected with these, to form the attested Tocharians.

The referenced text by Thorkild Jakobsen offers the interesting linguistic data:

Among the Gutian rulers is one Elulumesh, whose name is evidently Akkadian Elulum slightly “Gutianized” by the Gutian case(?) ending -eš.40 This Gutian ruler Elulum is obviously the same man whom we find participating in the scramble for power after the death of Shar-kali-sharrii; his name appears there in Sumerian form without mimation as Elulu.

The Gutian dynasty, from ca. 22nd c. BC appears as follows:

gutian-rulers

I don’t think we could derive a potential relation to any specific Indo-European branch from this simple suffix repeated in Gutian rulers, though.

The hypothesis of the Tocharian-like nature of the Guti (apart from the obvious error of considering them as the ancestors of Tocharians) remains not contrasted in new works since. It was cited e.g. by Gamkrelidze and Ivanov (1995) to advance their Armenian homeland, and by Mallory and Adams in their Encyclopedia (1997).

It lies therefore in the obscurity of undeveloped archaeological-linguistic hypotheses, and its connection with the attested R1b-Z2103 samples from Iran is not (yet) warranted.

Eurasian steppe dominated by Iranian peoples, Indo-Iranian expanded from East Yamna

yamna-indo-iranian-expansion

The expected study of Eurasian samples is out (behind paywall): 137 ancient human genomes from across the Eurasian steppes, by de Barros Damgaard et al. Nature (2018).

Dicussion (emphasis mine):

Our findings fit well with current insights from the historical linguistics of this region (Supplementary Information section 2). The steppes were probably largely Iranian-speaking in the first and second millennia bc. This is supported by the split of the Indo-Iranian linguistic branch into Iranian and Indian33, the distribution of the Iranian languages, and the preservation of Old Iranian loanwords in Tocharian34. The wide distribution of the Turkic languages from Northwest China, Mongolia and Siberia in the east to Turkey and Bulgaria in the west implies large-scale migrations out of the homeland in Mongolia since about 2,000 years ago35. The diversification within the Turkic languages suggests that several waves of migration occurred36 and, on the basis of the effect of local languages, gradual assimilation to local populations had previously been assumed37. The East Asian migration starting with the Xiongnu accords well with the hypothesis that early Turkic was the major language of Xiongnu groups38. Further migrations of East Asians westwards find a good linguistic correlate in the influence of Mongolian on Turkic and Iranian in the last millennium39. As such, the genomic history of the Eurasian steppes is the story of a gradual transition from Bronze Age pastoralists of West Eurasian ancestry towards mounted warriors of increased East Asian ancestry—a process that continued well into historical times.

This paper will need a careful reading – better in combination with Narasimhan et al. (2018), when their tables are corrected – , to assess the actual ‘Iranian’ nature of the peoples studied. Their wide and long-term dominion over the steppe could also potentially explain some early samples from Hajji Firuz with steppe ancestry.

Principal component analyses. The principal components 1 and 2 were plotted for the ancient data analysed with the present-day data (no projection bias) using 502 individuals at 242,406 autosomal SNP positions. Dimension 1 explains 3% of the variance and represents a gradient stretching from Europe to East Asia. Dimension 2 explains 0.6% of the variance, and is a gradient mainly represented by ancient DNA starting from a ‘basal-rich’ cluster of Natufian hunter-gatherers and ending with EHGs. BA, Bronze Age; EMBA, Early-to-Middle Bronze Age; SHG, Scandinavian hunter-gatherers.

For the moment, at first sight, it seems that, in terms of Y-DNA lineages:

  • R1b-Z93 (especially Z2124 subclades) dominate the steppes in the studied periods.
  • R1b-P312 is found in Hallstatt ca. 810 BC, which is compatible with its role in the Celtic expansion.
  • R1b-U106 is found in a West Germanic chieftain in Poprad (Slovakia) ca. 400 AD, during the Migration Period, hence supporting once again the expansion of Germanic tribes especially with R1b-U106 lineages.
  • A new sample of N1c-L392 (L1025) lineage dated ca. 400 AD, now from Lithuania, points again to a quite late expansion of this lineage to the region, believed to have hosted Uralic speakers for more than 2,000 years before this.
  • A sample of haplogroup R1a-Z282 (Z92) dated ca. 1300 AD in the Golden Horde is probably not quite revealing, not even for the East Slavic expansion.
  • Also, interestingly, some R1b(xM269) lineages seem to be associated with Turkic expansions from the eastern steppe dated around 500 AD, which probably points to a wide Eurasian distribution of early R1b subclades in the Mesolithic.

NOTE. I have referenced not just the reported subclades from the paper, but also (and mainly) further Y-SNP calls studied by Open Genomes. See the spreadsheet here.

Interesting also to read in the supplementary materials the following, by Michaël Peyrot (emphasis mine):

1. Early Indo-Europeans on the steppe: Tocharians and Indo-Iranians

The Indo-European language family is spread over Eurasia and comprises such branches and languages as Greek, Latin, Germanic, Celtic, Sanskrit etc. The branches relevant for the Eurasian steppe are Indo-Aryan (= Indian) and Iranian, which together form the Indo-Iranian branch, and the extinct Tocharian branch. All Indo-European languages derive from a postulated protolanguage termed Proto-Indo-European. This language must have been spoken ca 4500–3500 BCE in the steppe of Eastern Europe21. The Tocharian languages were spoken in the Tarim Basin in present-day Northwest China, as shown by manuscripts from ca 500–1000 CE. The Indo-Aryan branch consists of Sanskrit and several languages of the Indian subcontinent, including Hindi. The Iranian branch is spread today from Kurdish in the west, through a.o. Persian and Pashto, to minority languages in western China, but was in the 2nd and 1st millennia BCE widespread also on the Eurasian steppe. Since despite their location Tocharian and Indo-Iranian show no closer relationship within Indo-European, the early Tocharians may have moved east before the Indo-Iranians. They are probably to be identified with the Afanasievo Culture of South Siberia (ca 2900 – 2500 BCE) and have possibly entered the Tarim Basin ca 2000 BCE103.

The Indo-Iranian branch is an extension of the Indo-European Yamnaya Culture (ca 3000–2400 BCE) towards the east. The rise of the Indo-Iranian language, of which no direct records exist, must be connected with the Abashevo / Sintashta Culture (ca 2100 – 1800 BCE) in the southern Urals and the subsequent rise and spread of Andronovo-related Culture (1700 – 1500 BCE). The most important linguistic evidence of the Indo-Iranian phase is formed by borrowings into Finno-Ugric languages104–106. Kuz’mina (2001) identifies the Finno-Ugrians with the Andronoid cultures in the pre-taiga zone east of the Urals107. Since some of the oldest words borrowed into Finno-Ugric are only found in Indo-Aryan, Indo-Aryan and Iranian apparently had already begun to diverge by the time of these contacts, and when both groups moved east, the Iranians followed the Indo-Aryans108. Being pushed by the expanding Iranians, the Indo-Aryans then moved south, one group surfacing in equestrian terminology of the Anatolian Mitanni kingdom, and the main group entering the Indian subcontinent from the northwest.

2. Andronovo Culture: Early Steppe Iranian

Initially, the Andronovo Culture may have encompassed speakers of Iranian as well as Indo-Aryan, but its large expansion over the Eurasian steppe is most probably to be interpreted as the spread of Iranians. Unfortunately, there is no direct linguistic evidence to prove to what extent the steppe was indeed Iranian speaking in the 2nd millennium BCE. An important piece of indirect evidence is formed by an archaic stratum of Iranian loanwords in Tocharian34,109. Since Tocharian was spoken beyond the eastern end of the steppe, this suggests that speakers of Iranian spread at least that far. In the west of the Tarim Basin the Iranian languages Khotanese and Tumshuqese were spoken. However, the Tocharian B word etswe ‘mule’, borrowed from Iranian *atswa- ‘horse’, cannot derive from these languages, since Khotanese has aśśa- ‘horse’ with śś instead of tsw. The archaic Iranian stratum in Tocharian is therefore rather to be connected with the presence of Andronovo people to the north and possibly to the east of the Tarim Basin from the middle of the 2nd millennium BCE onwards110.

Since Kristiansen and Allentoft sign the paper (and Peyrot is a colleague of Kroonen), it seems that they needed to expressly respond to the growing criticism about their recent Indo-European – Corded Ware Theory. That’s nice.

They are obviously trying to reject the Corded Ware – Uralic links that are on the rise lately among Uralicists, now that Comb Ware is not a suitable candidate for the expansion of the language family.

IECWT-proponents are apparently not prepared to let it go quietly, and instead of challenging the traditional Neolithic Uralic homeland in Eastern Europe with a recent paper on the subject, they selected an older one which partially fit, from Kuz’mina (2001), now shifting the Uralic homeland to the east of the Urals (when Kuz’mina asserts it was south of the Urals).

Different authors comment later in this same paper about East Uralic languages spreading quite late, so even their text is not consistent among collaborating authors.

Also interesting is the need to resort to the questionable argument of early Indo-Aryan loans – which may have evidently been Indo-Iranian instead, since there is no way to prove a difference between both stages in early Uralic borrowings from ca. 4,500-3,500 years ago…

EDIT (10/5/2018) The linguistic supplement of the Science paper deals with different Proto-Indo-Iranian stages in Uralic loans, so on the linguistic side at least this influence is clear to all involved.

A rejection of such proposals of a late, eastern homeland can be found in many recent writings of Finnic scholars; see e.g. my references to Parpola (2017), Kallio (2017), or Nordqvist (2018).

NOTE. I don’t mind repeating it again: Uralic is one possibility (the most likely one) for the substrate language that Corded Ware migrants spread, but it could have been e.g. another Middle PIE dialect, similar to Proto-Anatolian (after the expansion of Suvorovo-Novodanilovka chiefs). I expressly stated this in the Corded Ware substrate hypothesis, since the first edition. What was clear since 2015, and should be clear to anyone now, is that Corded Ware did not spread Late PIE languages to Europe, and that some east CWC groups only spread languages to Asia after admixing with East Yamna. If they did not spread Uralic, then it was a language or group of languages phonetically similar, which has not survived to this day.

Their description of Yamna migrations is already outdated after Olalde et al. & Mathieson et al. (2018), and Narasimhan et al. (2018), so they will need to update their model (yet again) for future papers. As I said before, Anthony seems to be one step behind the current genetic data, and the IECWT seems to be one step behind Anthony in their interpretations.

At least we won’t have the Yamna -> Corded Ware -> BBC nonsense anymore, and they expressly stated that LPIE is to be associated with Yamna, and in particular the “Indo-Iranian branch is an extension of the Indo-European Yamnaya Culture (ca 3000–2400 BCE) to the East” (which will evidently show an East Yamna / Poltavka society of R1b-L23 subclades), so that earlier Eneolithic cultures have to be excluded, and Balto-Slavic identification with East Europe is also out of the way.

Lazaridis’ evolutionary history of human populations in Europe

Preprint of a review by Iosif Lazaridis, The evolutionary history of human populations in Europe.

Interesting excerpts:

Steppe populations during the Eneolithic to Bronze Age were a mix of at least two elements[28], the EHG who lived in eastern Europe ~8kya and a southern population element related to present-day Armenians[28], and ancient Caucasus hunter-gatherers[22], and farmers from Iran[24]. Steppe migrants made a massive impact in Central and Northern Europe post- 5kya[28,43]. Some of them expanded eastward, founding the Afanasievo culture[43] and also eventually reached India[24]. These expansions are probable vectors for the spread of Late Proto-Indo-European[44] languages from eastern Europe into both mainland Europe and parts of Asia, but the lack of steppe ancestry in the few known samples from Bronze Age Anatolia[45] raises the possibility that the steppe was not the ultimate origin of Proto-Indo-European (PIE), the common ancestral language of Anatolian speakers, Tocharians, and Late Proto-Indo Europeans. In the next few years this lingering mystery will be solved: either Anatolian speakers will be shown to possess steppe-related ancestry absent in earlier Anatolians (largely proving the steppe PIE hypothesis), or they will not (largely falsifying it, and pointing to a Near Eastern PIE homeland).

Our understanding of the spread of steppe ancestry into mainland Europe is becoming increasingly crisp. Samples from the Bell Beaker complex[46] are heterogeneous, with those from Iberia lacking steppe ancestry that was omnipresent in those from Central Europe, casting new light on the “pots vs. people” debate in archaeology, which argues that it is dangerous to propose a tight link between material culture and genetic origins. Nonetheless, it is also dangerous to dismiss it completely. Recent studies have shown that people associated with the Corded Ware culture in the Baltics[23,33] were genetically similar to those from Central Europe and to steppe pastoralists[28,43], and the people associated with the Bell Beaker culture in Britain traced ~90% of their ancestry to the continent, being highly similar to Bell Beaker populations there. Bell Beaker-associated individuals were bearers of steppe ancestry into the British Isles that was also present in Bronze Age Ireland[47], and Iron Age and Anglo-Saxon England[48]. The high genetic similarity between people from the British Isles and those of the continent makes it more difficult to trace migrations into the Isles. This high similarity masks a very detailed fine-scale population structure that has been revealed by study of present-day individuals[49]; a similar type of analysis applied to ancient DNA has the potential to reveal fine-grained population structure in ancient European populations as well.

Steppe ancestry did arrive into Iberia during the Bronze Age[50], but to a much lesser degree. A limited effect of steppe ancestry in Iberia is also shown by the study of mtDNA[51], which shows no detectible change during the Chalcolithic/Early Bronze Age[51], in contrast to central Europe[52]. Sex-biased gene flow has been implicated in the spread of steppe ancestry into Europe[33,53], although the presence and extent of such bias has been debated[54,55]. One aspect of the demographies of males and females was clearly different, as paternally-inherited Y-chromosome lineages experienced a bottleneck <10 kya which is not evident in maternally-inherited mtDNA[56], suggesting that many men living today trace their patrilineal ancestry to a relatively small number of men of the Neolithic and Bronze Ages.

lazaridis-europe
Modified image, from the preprint. “A sketch of European evolutionary history based on ancient DNA. Bronze Age Europeans (~4.5-3kya) were a mixture of mainly two proximate sources of ancestry: (i) the Neolithic farmers of ~8-5kya who were themselves variable mixtures of farmers from Anatolia and hunter-gatherers of mainland Europe (WHG), and (ii) Bronze Age steppe migrants of ~5kya who were themselves a mixture of hunter-gatherers of eastern Europe (EHG) and southern populations from the Near East (…)”

Firstly, Tocharian (mentioned side by side with Anatolian and LPIE) has been discussed by linguists for quite some time now to be a more archaizing language than the rest, hence the linguistic proposal that it separated first – found to correspond beautifully with the expansion of Khvalynsk/Repin into Afanasevo – ; but it separated first from the common Late PIE trunk. Anatolian clearly separated earlier, from a Middle PIE stage.

Secondly, while Genomics could no doubt falsify the Balkan route for Anatolian, and make us come back to a Maykop route from the steppe (or even a Near Eastern PIE homeland, who knows), I doubt such falsification could come simply from sampled “Anatolian speakers”:

If there is no steppe ancestry in Anatolian speakers (of the 2nd millennium BC), a dismissal of the mainstream migration model could happen only when both potential routes of expansion, the selected cultures from the Balkans and the Caucasus, are sampled in the appropriate time period since the estimated separation (i.e. from the 5th millennium BC), until one of both routes shows the right migration picture.

On the other hand, if some samples from either Romania/Bulgaria or the Caucasus (and/or Anatolian speakers) show steppe ancestry and/or R1b-M269 lineages, as is expected, then the matter won’t need much more explanation.

In fact, the text goes on to define how male lineages experienced a bottleneck after ca. 8000 BC, i.e. accompanying Neolithisation – probably including the formation of Sredni Stog and early Khvalynsk, as it is becoming now clear – , when explaining how it is possible to demonstrate that East Bell Beaker migrants (of R1b-L23 lineages, it is to be understood) with few steppe ancestry reached Iberia.

This was already pointed out not long ago by David Reich, and I am glad to see more scholars showing the importance of taking phylogeography into account over statistical methods when assessing migrations, even if it is only used in those cases in which it does not disrupt too much previous interpretations, like that of the 2015 papers and the proposal of the ‘Yamnaya ancestral component’.

I found it refreshing that for the first time Corded Ware migrants – or, rather, their shared genetic relationship with Eneolithic steppe groups – were accepted (if only indirectly) as a confounding factor in assessing migrations of Bell Beakers. It is a step in the right direction, and it is a relief to read this from someone working with the Reich Lab.

Not just a few (and not only amateurs) are still scratching their heads trying to explain with the most imaginative (and unnecessary) novel migration routes the elevated steppe ancestry and closer relation (PCA cluster, FST, F3, etc.) to CWC and Yamna (due evidently to the absorbed CWC population) in some of the recently published Bell Beaker samples from Central Europe, the Netherlands, and later in Great Britain, compared to samples of South-East Europe near the Middle to Upper Danube region, the obvious homeland of East Bell Beakers, formed from Yamna settlers.

I found it also interesting that Lazaridis mentioned a southern population element related to CHG and Iran farmers. This should help dissipate the hype that some have artificially created as of late over a potential Northern Iranian homeland based on a single paragraph from David Reich’s book.

EDIT (9 MAY 2018). Lazaridis posted an answer to my questioning of potential Proto-Anatolian origins divided in tweets (I post a link to the first tweet, then the text in full):

The steppe hypothesis predicts some genetic input from eastern Europe (EHG) to Anatolia.

– Bronze Age Anatolians (Lazaridis et al. 2017) from historically IE-speaking Pisidia lack EHG; more samples obviously needed

Possibilities:

  1. Additional Anatolian samples will have EHG: consistent with steppe PIE
  2. Additional Anatolian samples will not have EHG, then either:
    1. Steppe not PIE homeland
    2. Steppe PIE homeland but linguistic impact in Anatolia vastly greater than genetic impact

Tentative steppe->Anatolia movements reach Balkans early (Mathieson et al. 2018) and Armenia (some EHG in Lazaridis et al. 2016).

But not the last leg to Anatolia_ChL (Lazaridis et al. 2016) or Anatolia_BA (Lazaridis et al. 2017).

  • If Anatolians consistently don’t have EHG, steppe PIE is very difficult to affirm; Near Eastern alternative likely (contributing CHG/Iran_N-related ancestry to both western Anatolia/steppe)
  • If Anatolians have EHG, one could further investigate by what route they got it.

One way or another PIE homeland problem is almost solved IMHO, which is what my review tries to get at in that short section

Domestication spread probably via the North Pontic steppe to Khvalynsk… but not horse riding

Interesting paper Excavation at the Razdolnoe site on the Kalmius river in 2010, by N. Kotova, D. Anthony, D. Brown, S. Degermendzhy, P. Crabtree, In: Archaeology and Palaeoecology of the Ukrainian Steppe / IA NAS of Ukraine, Kyiv 2017.

Nothing new probably to those who have read Anthony (2007), but this new publication of his research on the North Pontic region seems to contradict recent papers which cast doubts on the presence of early forms of domestication in the North Pontic steppe, and would reject thus also the arrival of domestication to Khvalynsk from a southern route.

Interesting excerpts discussing recent research and results of this one (emphasis mine):

A brief comment about the fauna is required. A separate international archaeological project studied sites dated to the mid — 6th millennium BC in the Severskiy Donets basin (Starobelsk I, Novoselovka III) northeast of Razdolnoe, and found that they had hunting and gathering economies that made use of Unio shellfish, fish, and turtles, like the Neolithic occupation at Razdolnoe. But the Donets sites had no domesticated animal species. The author argued that the cultures of the Donets and lower Don basins in the 6th millennium BC probably had no domesticated animals, and that the domesticated sheep-goat bones identified at Semenovka, west of Razdolnoe, and dated to 5500 calBC, probably were mis-identified and actually came from wild saiga antelope (Motuzaite- Matuzeviciute 2012: 14). This suggestion was made on the basis of a single bone identified as sheep-goat at Semenovka by O.P. Zhuravlev (not N.S. Kotova as Motuzaite-Matuzeviciute wrote) and sent out for radiocarbon dating, that was re-examined by Cambridge University archaeozoologists.

Regardless of which identification is correct, a single bone is insufficient to cast doubt on sheep-goat bones identified at Sredni Stog 1, Sobachki, and other Neolithic sites in the Dnieper valley. Nevertheless, yet another international collaboration that studied the economy of Dereivka in the Dnieper valley argued that the economy of Eneolithic Dereivka site, which they dated to about 3500 calBC (ignoring 10 radiocarbon dates between 4200—3700 calBC), was still at an «initial phase of animal domestication» and that the Dereivka occupants of 3500 calBC were still largely dependent on hunting and fishing (Mileto et al. 2017: 67—68).

The dated Bos calf in the lower occupation level at Razdolnoe shows that domesticated animals were present in the Kalmius river valley in the Azov steppes in 5500 calBC, at a time when the cultures of the Donets valley were still hunters and gatherers just 200 km to the northeast of Razdolnoe. Sheep-goat and Bos bones were found in all Neolithic and Eneolithic levels at Razdolnoe. Because it was a small excavation, this evidence should not be over-interpreted. We cannot say how important domesticated animals were in the daily diet. But domesticated sheep-goat and cows had reached the Azov steppes by 5500 calBC. The appearance of cattle and sheep-goat as sacrificial animals in graves of the Khvalynsk Culture on the Volga by the early 5th millennium BC probably was a continuation of the spread of animal herding eastward from the Azov steppes.

neolithic_steppe-anatolian-migrations
Most likely route of expansion of horse domestication and horse riding (including Suvorovo-Novodanilovka chiefs) from Khvalynsk into the North Pontic steppe and the Balkans.

Re-reading the papers on this subject – in which researchers seem to be fighting among each other for a radical interpretation of few animal bones – , I would suggest that the key concept they should be emphasizing is probably not the ‘presence’ vs. ‘absence’ of domestication in North Pontic steppe cultures in absolute terms.

Since there were clearly domesticated animals to the east and west of North Pontic cultures in the Neolithic, and thus the finding there of domesticated animals is more than likely, what is of great interest is the relative measure in which domesticated animals were relied upon by forest-steppe economies, compared to the use of available natural resources.

After all, many researchers currently agree that the North Pontic steppe and forest-steppe peoples formed communities of mainly hunter-fishers and gatherers, and findings of this paper do not seem to contradict this.

NOTE. In fact, there was a more recent paper I referenced which argues in such general terms with detail – probably written at the same time as this one -, by one of the authors they discuss, Mileto et al. (2018).

Also, as the paper states,

we want to emphasize that even a small excavation in the steppe zone, where only scanty number of the Neolithic and Eneolithic sites have been known yet, is very important and always gives very interesting materials.

Hence by confirming Anthony’s account of early domestication spreading eastwards during the Neolithic expansion, and without horses’ remains in any of the periods investigated (including Sredni Stog I-III), it also supports his hypothesis of horse riding emerging in Khvalynsk and expanding westward.

The Razdolnoe site lies near modern-day Donetsk, and its latest layer investigated (ca. 4300-4150 BC) represents thus the eastern variant of Sredni Stog III, being consequently the one more in contact with expanding early Khvalynsk.

Given the absence of horse remains in all layers, these results would also suggest that Novodanilovka and Suvorovo horse-riding chiefs (emerging ca. 4400-4200 BC to the west of this region) were indeed unrelated to the surrounding Sredni Stog population, and most likely migrants from the horse-riding Khvalynsk culture.
