Palaeolithic Caucasus samples reveal the most important component of West Eurasians


Preprint Paleolithic DNA from the Caucasus reveals core of West Eurasian ancestry, by Lazaridis et al. bioRxiv (2018).

Interesting excerpts:

We analyzed teeth from two individuals 63 recovered from Dzudzuana Cave, Southern Caucasus, from an archaeological layer previously dated to ~27-24kya (…). Both individuals had mitochondrial DNA sequences (U6 and N) that are consistent with deriving from lineages that are rare in the Caucasus or Europe today. The two individuals were genetically similar to each other, consistent with belonging to the same population and we thus analyze them jointly.

(…) our results prove that the European affinity of Neolithic Anatolians does not necessarily reflect any admixture into the Near East from Europe, as an Anatolian Neolithic-like population already existed in parts of the Near East by ~26kya. Furthermore, Dzudzuana shares more alleles with Villabruna-cluster groups than with other ESHG (Extended Data Fig. 5b), suggesting that this European affinity was specifically related to the Villabruna cluster, and indicating that the Villabruna affinity of PGNE populations from Anatolia and the Levant is not the result of a migration into the Near East from Europe. Rather, ancestry deeply related to the Villabruna cluster was present not only in Gravettian and Magdalenian-era Europeans but also in the populations of the Caucasus, by ~26kya. Neolithic Anatolians, while forming a clade with Dzudzuana with respect to ESHG, share more alleles with all other PGNE (Extended Data Fig. 5d), suggesting that PGNE share at least partially common descent to the exclusion of the much older samples from Dzudzuana.

Our co-modeling of Epipaleolithic Natufians and Ibero-Maurusians from Taforalt confirms that the Taforalt population was mixed, but instead of specifying gene flow from the ancestors of Natufians into the ancestors of Taforalt as originally reported, we infer gene flow in the reverse direction (into Natufians). The Neolithic population from Morocco, closely related to Taforalt is also consistent with being descended from the source of this gene flow, and appears to have no admixture from the Levantine Neolithic (Supplementary Information 166 section 3). If our model is correct, Epipaleolithic Natufians trace part of their ancestry to North Africa, consistent with morphological and archaeological studies that indicate a spread of morphological features and artifacts from North Africa into the Near East. Such a scenario would also explain the presence of Y-chromosome haplogroup E in the Natufians and Levantine farmers, a common link between the Levant and Africa.

(…) we cannot reject the hypothesis that Dzudzuana and the much later Neolithic Anatolians form a clade with respect to ESHG (P=0.286), consistent with the latter being a population largely descended from Dzudzuana-like pre-Neolithic populations whose geographical extent spanned both Anatolia and the Caucasus. Dzudzuana itself can be modeled as a 2-way mixture of Villabruna-related ancestry and a Basal Eurasian lineage.

In qpAdm modeling, a deeply divergent hunter-gatherer lineage that contributed in relatively unmixed form to the much later hunter-gatherers of the Villabruna cluster is specified as contributing to earlier hunter-gatherer groups (Gravettian Vestonice16: 35.7±11.3% and Magdalenian ElMiron: 60.6±11.3%) and to populations of the Caucasus (Dzudzuana: 199 72.5±3.7%, virtually identical to that inferred using ADMIXTUREGRAPH). In Europe, descendants of this lineage admixed with pre-existing hunter-gatherers related to Sunghir3 from Russia for the Gravettians and GoyetQ116-1 from Belgium for the Magdalenians, while in the Near East it did so with Basal Eurasians. Later Europeans prior to the arrival of agriculture were the product of re-settlement of this lineage after ~15kya in mainland Europe, while in eastern Europe they admixed with Siberian hunter-gatherers forming the WHG-ANE cline of ancestry [See PCA above]. In the Near East, the Dzudzuana-related population admixed with North African-related ancestry in the Levant and with Siberian hunter-gatherer and eastern non-African-related ancestry in Iran and the Caucasus. Thus, the highly differentiated populations at the dawn of the Neolithic were primarily descended from Villabruna Cluster and Dzudzuana-related ancestors, with varying degrees of additional input related to both North Africa and Ancient North/East Eurasia whose proximate sources may be clarified by future sampling of geographically and temporally intermediate populations.

An admixture graph model of Paleolithic West Eurasians. An automatically generated admixture graph models fits populations (worst Z-score of the difference between estimated and fitted f-statistics is 2.7) or populations (also including South_Africa_HG, worst Z-score is 3.5). This is a simplified model assuming binary admixture events and is not a unique solution (Supplementary Information section 2). Sampled populations are shown with ovals and select labeled internal nodes with rectangles.

Interesting excerpts from the supplementary materials:

From our analysis of Supplementary Information section 3, we showed that these sources are indeed complex, and only one of these (WHG, represented by Villabruna) appears to be a contributor to all the remaining sources. This should not be understood as showing that hunter-gatherers from mainland Europe migrated to the rest of West Eurasia, but rather that the fairly homogeneous post-15kya population of mainland Europe labeled WHG appear to represent a deep strain of ancestry that seems to have contributed to West Eurasians from the Gravettian era down to the Neolithic period.

Villabruna is representative of the WHG group. We also include ElMiron, the best sample from the Magdalenian era as we noticed that within the WHG group there were individuals that could not be modeled as a simple clade with Villabruna but also had some ElMiron-related ancestry. Ddudzuana is representative of the Ice Age Caucasus population, differentiated from Villabruna by Basal Eurasian ancestry. AG3 represents ANE/Upper Paleolithic Siberian ancestry, sampled from the vicinity of Lake Baikal, while Russia_Baikal_EN related to eastern Eurasians and represents a later layer of ancestry from the same region of Siberia as AG3 Finally, Mbuti are a deeply diverged African population that is used here to represent deep strains of ancestry (including Basal Eurasian) prior to the differentiation between West Eurasians and eastern non-Africans that are otherwise not accounted for by the remaining five sources. Collectively, we refer to this as ‘Basal’ or ‘Deep’ ancestry, which should be understood as referring potentially to both Basal Eurasian and African ancestry.

It has been suggested that there is an Anatolia Neolithic-related affinity in hunter-gatherers from the Iron Gates. Our analysis confirms this by showing that this population has Dzudzuana-related ancestry as do many hunter-gatherer populations from southeastern Europe, eastern Europe and Scandinavia. These populations cannot be modeled as a simple mixture of Villabruna and AG3 but require extra Dzudzuana-related ancestry even in the conservative estimates, with a positive admixture proportion inferred for several more in the speculative ones. Thus, the distinction between European hunter-gatherers and Near Eastern populations may have been gradual in pre-Neolithic times; samples from the Aegean (intermediate between those from the Balkans and Anatolia) may reveal how gradual the transition between Dzudzuana-like Neolithic Anatolians and mostly Villabruna-like hunter-gatherers was in southeastern Europe.

Modified image (cut, with important samples marked). 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 365 split of Ust’Ishim, Tianyuan, and West Eurasians and can include both ‘Basal Eurasian’ and other (e.g., Sub-Saharan African) ancestry. (a) ‘Conservative’ estimates. Each population 367 cannot be modeled with fewer admixture events than shown.

Villabruna: This type of ancestry differentiates between present-day Europeans and non-Europeans within West Eurasia, attaining a maximum of ~20% in the Baltic in accordance with previous observations and with the finding of a later persistence of significant hunter-gatherer ancestry in the region. Its proportion drops to ~0% throughout the Near East. Interestingly, a hint of such ancestry is also inferred in all North African populations west of Libya in the speculative proportions, consistent with an archaeogenetic inference of gene flow from Iberia to North Africa during the Late Neolithic.

ElMiron: This type of ancestry is absent in present-day West Eurasians. This may be because most of the Villabruna-related ancestry in Europeans traces to WHG populations that lacked it (since ElMiron-related ancestry is quite variable within European hunter-gatherers). However, ElMiron ancestry makes up only a minority component of all WHG populations sampled to date and WHG-related ancestry is a minority component of present-day Europeans. Thus, our failure to detect it in present day people may be simply be too little of it to detect with our methods.

Dzudzuana: Our analysis identifies Dzudzuana-related ancestry as the most important component of West Eurasians and the one that is found across West Eurasian-North African populations at ~46-88% levels. Thus, Dzudzuana-related ancestry can be viewed as the common core of the ancestry of West Eurasian-North African populations. Its distribution reaches its minima in northern Europe and appears to be complementary to that of Villabruna, being most strongly represented in North Africa, the Near East (including the Caucasus) and Mediterranean Europe. Our results here are expected from those of Supplementary Information section 3 in which we modeled ancient Near Eastern/North African populations (the principal ancestors of present-day people from the same regions) as deriving much of their ancestry from a Dzudzuana-related source. Migrations from the Near East/Caucasus associated with the spread of the Neolithic, but also the formation of steppe population introduced most of the Dzudzuana-related ancestry present in Europe, although (as we have seen above) some such ancestry was already present in some pre-agricultural hunter-gatherers in Europe.

AG3: Ancestry related to the AG3 sample from Siberia has a northern distribution, being strongly represented in both central-northern Europe and the north Caucasus.

Russia_Baikal_EN: Ancestry related to hunter-gatherers from Lake Baikal in Siberia (postdating AG3) appears to have affected primarily northeastern European populations which have been previously identified as having East Eurasian ancestry; some such ancestry is also identified for a Turkish population from Balıkesir, likely reflecting the Central Asian ancestry of Turkic speakers which has been recently confirmed directly in an Ottoman sample from Anatolia.

Some comments

So, to try and sum up:

  • Dzudzuana shares ancestry with ‘Common West Eurasian’ (CWE). the ancestor cluster of Villabruna.
  • Dzudzuana diverges from CWE because of a Basal Eurasian ancestry contribution [which supports that Basal Eurasian ancestry was a deep Middle Eastern lineage].
  • Dzudzuana is closest to Anatolia Neolithic, and close to Gravettian.

  1. Aurignacian: First West Eurasians arrive ca. 36,000 BP, Goyet cluster expands probably with C1a2 lineages.
  2. After that, the early or ‘unmixed’ Villabruna cluster (‘hidden’ somewhere probably east of Europe, either North Eurasia or South Eurasia), lineages unknown (possibly IJ), contributes to:
    1. Gravettian (ca. 30,000 BP): Věstonice cluster expands, probably with IJ lineages.
    2. A (hidden) ‘Common West Eurasian’ population.
    3. In turn:

      • Dzudzuana ca. 26,000 BP derived from Common West Eurasian (curiously, haplogroup G seems to split in today’s subclades ca. 26,000 BP).
      • During the Gravettian (ca. 26,000 BP), an Anatolian Neolithic-like population exists already in the Near East. Both Věstonice and this Anatolian HG are close to Dzudzuana; in turn, Dzudzuana from CWE.

    4. Magdalenian (ca. 20,000 BP): El Mirón cluster expands, probably with more specific I lineages.
  3. Bølling-Allerød warming period (ca. 14,000 BP): ‘late’ Villabruna cluster or WHG (=CWE with greater affinity to Near Eastern populations) expands, probably spreading with R1b in mainland Europe and to the east (admixing with Siberian HG), creating the WHG — ANE ancestry cline, as reflected in Iron Gates HG, Baltic HG, etc.

[Here we have the possible “bidirectional gene flow between populations ancestral to Southeastern Europeans of the early Holocene and Anatolians of the late glacial or a dispersal of Southeastern Europeans into the Near East” inferred from Anatolian hunter-gatherers]

The Gravettian (30,000 to 20,000 years) is drawn in black and white; the subsequent Magdalenian (17,000 to 10,000 years) and Hamburgian (13,000-11,750 years) are in light blue and red. It is not known whether the spread of the Gravettian was a result of diffusion of people or cultures. This figure illustrates the possible monocentric origins of the Gravettian, in which the Gravettian is hypothesized to have its origin in the Middle Danube Basin, first spreading west (solid lines) and later spreading east and southeast (dashed lines). This scenario is largely based on the chronology of sites. Thus far, genome-wide data has been collected from only three of the ten< Gravettian regions indicated on the map. These regions are northern Austria (1 sample), the Czech Republic (6), southern Italy (3) and Belgium (3), indicating that they all share a genomic ancestry. However, it is unknown whether samples from the remaining regions also share a close genomic ancestry. Some skeletal remains associated with the Gravettian that could be investigated paleogenomically are from Sungir (Russia); Laghar Velho (central Portugal); Cussac Cave; Les Garennes, near Vilhonneur; and Level 2 at Abri Pataud116 (western France). Light blue and light red regions represent the approximate distributions of the Magdalenian Culture and the Hamburgian Culture (13,000-11,750 years). Figure adapted from Kozłowski.

The paper talks about possibilities for Common West Eurasian:

  1. Migration from mainland Europe to Near East or vice versa (not very likely);
  2. Migration from a geographically intermediate Ice Age refugium in southeast Europe, Anatolia, or the circum-Pontic region that explain post-glacial affinity of post-glacial Levantine and Anatolian populations.

It also re-states what was known:

  • EHG (ca. 8,000 BP) = between WHG — ANE (ca. 24,000 BP).
  • CHG (ca. 10,000 BP) = between EHG — Iran N.

I would say that the distinct CHG vs. Dzudzuana ancestry puts CHG probably to the south, within the Iranian Plateau, during the Gravettian, expanding probably later.

Also important, Ancestral North African probably accompanied by haplogroup E. Early expansion of North Africans into the Near East further confirms the impossibility of Afroasiatic (much younger) to be associated with these expansions, and confirms that the still unclear Green Sahara migrations are the key.


Migrations in the Levant region during the Chalcolithic, also marked by distinct Y-DNA


Open access Ancient DNA from Chalcolithic Israel reveals the role of population mixture in cultural transformation, by Harney et al. Nature Communications (2018).

Interesting excerpts (emphasis mine, reference numbers deleted for clarity):


The material culture of the Late Chalcolithic period in the southern Levant contrasts qualitatively with that of earlier and later periods in the same region. The Late Chalcolithic in the Levant is characterized by increases in the density of settlements, introduction of sanctuaries, utilization of ossuaries in secondary burials, and expansion of public ritual practices as well as an efflorescence of symbolic motifs sculpted and painted on artifacts made of pottery, basalt, copper, and ivory. The period’s impressive metal artifacts, which reflect the first known use of the “lost wax” technique for casting of copper, attest to the extraordinary technical skill of the people of this period.

The distinctive cultural characteristics of the Late Chalcolithic period in the Levant (often related to the Ghassulian culture, although this term is not in practice applied to the Galilee region where this study is based) have few stylistic links to the earlier or later material cultures of the region, which has led to extensive debate about the origins of the people who made this material culture. One hypothesis is that the Chalcolithic culture in the region was spread in part by immigrants from the north (i.e., northern Mesopotamia), based on similarities in artistic designs. Others have suggested that the local populations of the Levant were entirely responsible for developing this culture, and that any similarities to material cultures to the north are due to borrowing of ideas and not to movements of people.

Previous genome-wide ancient DNA studies from the Near East have revealed that at the time when agriculture developed, populations from Anatolia, Iran, and the Levant were approximately as genetically differentiated from each other as present-day Europeans and East Asians are today. By the Bronze Age, however, expansion of different Near Eastern agriculturalist populations — Anatolian, Iranian, and Levantine — in all directions and admixture with each other substantially homogenized populations across the region, thereby contributing to the relatively low genetic differentiation that prevails today. Showed that the Levant Bronze Age population from the site of ‘Ain Ghazal, Jordan (2490–2300 BCE) could be fit statistically as a mixture of around 56% ancestry from a group related to Levantine Pre-Pottery Neolithic agriculturalists (represented by ancient DNA from Motza, Israel and ‘Ain Ghazal, Jordan; 8300–6700 BCE) and 44% related to populations of the Iranian Chalcolithic (Seh Gabi, Iran; 4680–3662 calBCE). Suggested that the Canaanite Levant Bronze Age population from the site of Sidon, Lebanon (~1700 BCE) could be modeled as a mixture of the same two groups albeit in different proportions (48% Levant Neolithic-related and 52% Iran Chalcolithic-related). However, the Neolithic and Bronze Age sites analyzed so far in the Levant are separated in time by more than three thousand years, making the study of samples that fill in this gap, such as those from Peqi’in, of critical importance.

This procedure produced genome-wide data from 22 ancient individuals from Peqi’in Cave (4500–3900 calBCE) (…)


We find that the individuals buried in Peqi’in Cave represent a relatively genetically homogenous population. This homogeneity is evident not only in the genome-wide analyses but also in the fact that most of the male individuals (nine out of ten) belong to the Y-chromosome haplogroup T, a lineage thought to have diversified in the Near East. This finding contrasts with both earlier (Neolithic and Epipaleolithic) Levantine populations, which were dominated by haplogroup E, and later Bronze Age individuals, all of whom belonged to haplogroup J.

Detailed sample background data for each of the 22 samples from which we successfully obtained ancient DNA. Additionally, background information for all samples from Peqi’in that were screened is included in Supplementary Data 1. *Indicates that Y-chromosome haplogroup call should be interpreted with caution, due to low coverage data.

Our finding that the Levant_ChL population can be well-modeled as a three-way admixture between Levant_N (57%), Anatolia_N (26%), and Iran_ChL (17%), while the Levant_BA_South can be modeled as a mixture of Levant_N (58%) and Iran_ChL (42%), but has little if any additional Anatolia_N-related ancestry, can only be explained by multiple episodes of population movement. The presence of Iran_ChL-related ancestry in both populations – but not in the earlier Levant_N – suggests a history of spread into the Levant of peoples related to Iranian agriculturalists, which must have occurred at least by the time of the Chalcolithic. The Anatolian_N component present in the Levant_ChL but not in the Levant_BA_South sample suggests that there was also a separate spread of Anatolian-related people into the region. The Levant_BA_South population may thus represent a remnant of a population that formed after an initial spread of Iran_ChL-related ancestry into the Levant that was not affected by the spread of an Anatolia_N-related population, or perhaps a reintroduction of a population without Anatolia_N-related ancestry to the region. We additionally find that the Levant_ChL population does not serve as a likely source of the Levantine-related ancestry in present-day East African populations.

These genetic results have striking correlates to material culture changes in the archaeological record. The archaeological finds at Peqi’in Cave share distinctive characteristics with other Chalcolithic sites, both to the north and south, including secondary burial in ossuaries with iconographic and geometric designs. It has been suggested that some Late Chalcolithic burial customs, artifacts and motifs may have had their origin in earlier Neolithic traditions in Anatolia and northern Mesopotamia. Some of the artistic expressions have been related to finds and ideas and to later religious concepts such as the gods Inanna and Dumuzi from these more northern regions. The knowledge and resources required to produce metallurgical artifacts in the Levant have also been hypothesized to come from the north.

Our finding of genetic discontinuity between the Chalcolithic and Early Bronze Age periods also resonates with aspects of the archeological record marked by dramatic changes in settlement patterns, large-scale abandonment of sites, many fewer items with symbolic meaning, and shifts in burial practices, including the disappearance of secondary burial in ossuaries. This supports the view that profound cultural upheaval, leading to the extinction of populations, was associated with the collapse of the Chalcolithic culture in this region.

I think the most interesting aspect of this paper is – as usual – the expansion of peoples associated with a single Y-DNA haplogroup. Given that the expansion of Semitic languages in the Middle East – like that of Anatolian languages from the north – must have happened after ca. 3100 BC, coinciding with the collapse of the Uruk period, these Chalcolithic north Levant peoples are probably not related to the posterior Semitic expansion in the region. This can be said to be supported by their lack of relationship with posterior Levantine migrations into Africa. The replacement of haplogroup E before the arrival of haplogroup J suggests still more clearly that Natufians and their main haplogroup were not related to the Afroasiatic expansions.

Distribution of Semitic languages. From Wikipedia.

On the other hand, while their ancestry points to neighbouring regional origins, their haplogroup T1a1a (probably T1a1a1b2) may be closely related to that of other Semitic peoples to the south, as found in east Africa and Arabia. This may be due either to a northern migration of these Chalcolithic Levantine peoples from southern regions in the 5th millennium BC, or maybe to a posterior migration of Semitic peoples from the Levant to the south, coupled with the expansion of this haplogroup, but associated with a distinct population. As we know, ancestry can change within certain generations of intense admixture, while Y-DNA haplogroups are not commonly admixed in prehistoric population expansions.

Without more data from ancient DNA, it is difficult to say. Haplogroup T1a1 is found in Morocco (ca. 3780-3650 calBC), which could point to a recent expansion of a Berbero-Semitic branch; but also in a sample from Balkans Neolithic ca. 5800-5400 calBCE, which could suggest an Anatolian origin of the specific subclades encountered here. In any case, a potential origin of Proto-Semitic anywhere near this wide Near Eastern region ca. 4500-3500 BC cannot be discarded, knowing that their ancestors came probably from Africa.

Distribution of haplogroup T of Y-chromosome. From Wikipedia.

Interesting from this paper is also that we are yet to find a single prehistoric population expansion not associated with a reduction of variability and expansion of Y-DNA haplogroups. It seems that the supposedly mixed Yamna community remains the only (hypothetical) example in history where expanding patrilineal clans will not share Y-DNA haplogroup…


“Steppe people seem not to have penetrated South Asia”


Open access structured abstract for The first horse herders and the impact of early Bronze Age steppe expansions into Asia from Damgaard et al. Science (2018) 360(6396):eaar7711.

Abstract (emphasis mine):

The Eurasian steppes reach from the Ukraine in Europe to Mongolia and China. Over the past 5000 years, these flat grasslands were thought to be the route for the ebb and flow of migrant humans, their horses, and their languages. de Barros Damgaard et al. probed whole-genome sequences from the remains of 74 individuals found across this region. Although there is evidence for migration into Europe from the steppes, the details of human movements are complex and involve independent acquisitions of horse cultures. Furthermore, it appears that the Indo-European Hittite language derived from Anatolia, not the steppes. The steppe people seem not to have penetrated South Asia. Genetic evidence indicates an independent history involving western Eurasian admixture into ancient South Asian peoples.

According to the commonly accepted “steppe hypothesis,” the initial spread of Indo-European (IE) languages into both Europe and Asia took place with migrations of Early Bronze Age Yamnaya pastoralists from the Pontic-Caspian steppe. This is believed to have been enabled by horse domestication, which revolutionized transport and warfare. Although in Europe there is much support for the steppe hypothesis, the impact of Early Bronze Age Western steppe pastoralists in Asia, including Anatolia and South Asia, remains less well understood, with limited archaeological evidence for their presence. Furthermore, the earliest secure evidence of horse husbandry comes from the Botai culture of Central Asia, whereas direct evidence for Yamnaya equestrianism remains elusive.

We investigated the genetic impact of Early Bronze Age migrations into Asia and interpret our findings in relation to the steppe hypothesis and early spread of IE languages. We generated whole-genome shotgun sequence data (~1 to 25 X average coverage) for 74 ancient individuals from Inner Asia and Anatolia, as well as 41 high-coverage present-day genomes from 17 Central Asian ethnicities.

Model-based admixture proportions for selected ancient and present-day individuals, assuming K = 6, shown with their corresponding geographical locations. Ancient groups are represented by larger admixture plots, with those sequenced in the present work surrounded by black borders and others used for providing context with blue borders. Present-day South Asian groups are represented by smaller admixture plots with dark red borders.

We show that the population at Botai associated with the earliest evidence for horse husbandry derived from an ancient hunter-gatherer ancestry previously seen in the Upper Paleolithic Mal’ta (MA1) and was deeply diverged from the Western steppe pastoralists. They form part of a previously undescribed west-to-east cline of Holocene prehistoric steppe genetic ancestry in which Botai, Central Asians, and Baikal groups can be modeled with different amounts of Eastern hunter-gatherer (EHG) and Ancient East Asian genetic ancestry represented by Baikal_EN.

In Anatolia, Bronze Age samples, including from Hittite speaking settlements associated with the first written evidence of IE languages, show genetic continuity with preceding Anatolian Copper Age (CA) samples and have substantial Caucasian hunter-gatherer (CHG)–related ancestry but no evidence of direct steppe admixture.

In South Asia, we identified at least two distinct waves of admixture from the west, the first occurring from a source related to the Copper Age Namazga farming culture from the southern edge of the steppe, who exhibit both the Iranian and the EHG components found in many contemporary Pakistani and Indian groups from across the subcontinent. The second came from Late Bronze Age steppe sources, with a genetic impact that is more localized in the north and west.

Our findings reveal that the early spread of Yamnaya Bronze Age pastoralists had limited genetic impact in Anatolia as well as Central and South Asia. As such, the Asian story of Early Bronze Age expansions differs from that of Europe. Intriguingly, we find that direct descendants of Upper Paleolithic hunter-gatherers of Central Asia, now extinct as a separate lineage, survived well into the Bronze Age. These groups likely engaged in early horse domestication as a prey-route transition from hunting to herding, as otherwise seen for reindeer. Our findings further suggest that West Eurasian ancestry entered South Asia before and after, rather than during, the initial expansion of western steppe pastoralists, with the later event consistent with a Late Bronze Age entry of IE languages into South Asia. Finally, the lack of steppe ancestry in samples from Anatolia indicates that the spread of the earliest branch of IE languages into that region was not associated with a major population migration from the steppe.

I think the wording of the abstract is weird, but consequent with their samples and results, so probably just clickbait / citebait for Indian journalists and social networks, or maybe a new attempt to ‘show respect for the sensibilities of Indians’ related to the artificially magnified “AIT vs. OIT” controversy, that is only present in India.

However, everything is possible, since it is brought to you by the same Danish group who proposed the Yamnaya ancestral component™, the CHG = Indo-European (and simultaneously EHG in Maykop = Anatolian??), and now also the CWC/R1a = Indo-European & Volosovo = Uralic

Here is the reaction of Narasimhan: Narasimhan has deleted the Tweet, it basically questioned the sentence that steppe people did not penetrate South Asia.


Trypillia and Greece Neolithic outliers: the smoking gun of Proto-Anatolian migrations?


(Continued from the post Corded Ware culture origins: The Final Frontier).

Looking at the PCA of Wang et al. (2018), I realized that Sredni Stog / Corded Ware peoples seem to lie somewhere between:

  • the eastern steppe (i.e. Khvalynsk-Yamna); and
  • Lower Danube and Balkan cultures affected by Anatolian- and steppe-related (i.e. Khvalynsk-Novodanilovka) migrations.

This multiethnic interaction of the western steppe fits therefore the complex archaeological description of events in the North Pontic, Lower Danube, and Dnieper-Dniester regions. Here are some interesting samples related to those long-lasting contacts:

1. I3719 (mtDNA H1, Y-DNA I2a2a) Ukraine Neolithic sample from Dereivka ca. 4949–4799 BC, described in Mathieson et al. (2018) as of “entirely northwestern-Anatolian-Neolithic-related ancestry”.

2. ANI163 from Varna I ca. 4711–4550 BC (mtDNA H7a1), and I2181 from Balkans Chalcolithic (Smyadovo, in Bulgaria) ca. 4500 BC (mtDNA HV15, Y-DNA R) show the first steppe ancestry in regions known to be affected by the expansion of Suvorovo chiefs.

3. The Yamna Bulgaria outlier (Y-DNA I2a2a1b1b), 3012-2900 calBCE, shows apparently an admixture with cultures of that region (but 1,500 years later).

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.

Trypillia and Corded Ware

4. There is one ‘Trypillia outlier’ among five samples from the Verteba cave in Wang et al. (2018): I1927 (Y-DNA G2a2b2a1a1b1a1a1, mtDNA H1b), ca. 3619-2936 BC, a sample published previously in Nikitin et al. (2017) and Mathieson et al. (2017). We were very quick to dismiss Trypillia (three samples of haplogroup G2a, one sample E) and GAC as a source of Corded Ware admixture, but archaeology clearly shows important population movements at the end of the fourth millennium between late Trypillia groups, GAC, and post-Sredni Stog populations, and genetics is showing that in both cultures, too.

I am not a fan of the ‘lack of samples’ argument, but (similar to Old Hittite samples related to all Anatolian speakers) one site is not enough to describe a culture that spanned millennia and many different early and late groups. One among five Trypillian samples (from a single site), showing a late date (ca. 3228 BC) compared to the other samples (ca. 3700 BC), and quite close to the only three Ukraine Eneolithic samples we have may mean much more than what we may a priori think, i.e. some simplistic unidirectional punctual ‘intrusion’ of steppe ancestry, and instead hint at the known close contacts of late Trypillian groups and North Pontic cultures, including also the Caucasus.

NOTE. The big difference in PCA among GAC-like Hungary LCA – EBA samples (see above two star symbols close to Ukraine Neolithic outlier in the PCA, in contrast with the other three at the bottom) may also be significant, although we don’t have any data about their culture, sites, or the relationship between them.

Greece Neolithic outlier: Proto-Anatolians?

5. Especially interesting is I6423, one of the Greece Neolithic samples referred to in Wang et al. (2018), which is obviously an outlier among the three used in the paper. It does not seem to correspond to any of the ancient DNA samples published to date; it is not in Hofmanova et al. (2016), in Lazaridis et al. (2017), or in Mathieson et al. (2018).

Since the Neolithic in Greece could mean any period from ca. 6500 BC to ca. 3200 BC, I guess we are talking here about some migration related to the expansion of Khvalynsk-Novodanilovka chieftains after ca. 4500 BC, because it appears on the PCA precisely on the same spot as Varna and Smyadovo outliers, and its ADMIXTURE shows similar components

Image modified from Wang et al. (2018). “ADMIXTURE results of relevant prehistoric individuals mentioned in the text (filled symbols)”. ‘Outlier’ samples referred to in this post have been marked in red. See the original file here.

So, this may be the smoking gun of Proto-Anatolian (or maybe early Common Anatolian) expansion with steppe migrants up to the border of Western Anatolia, and we may be able to get rid of those unfounded doubts about Anatolian origins once and for all…

NOTE. Also interesting seems another Greece Neolithic sample, I6420, in ADMIXTURE, although its position in the PCA (near Minoans and Mycenaeans) does not necessarily point to potential steppe influence, but rather to the extra ‘eastern (Caucasus/Iran-related) ancestry’ contribution found in Minoans and in Mycenaeans (and Anatolia Chalcolithic) compared to previous samples of the region. The third Greece Nelithic sample, I5427 (mtDNA K1a24), from Diros, Alepotrypa Cave, is dated 6005-5879 BC (mean 5892 BC), and appeared first in Mathieson et al. (2018).

If this Greece Neolithic sample is not related to Yamna migrations – and its use for statistical analysis of Caucasus samples from Wang et al. (2018) suggests that it is not – , it may have important consequences:

If it is located near the Western Anatolian coast – especially near Troy – there won’t be much to add about the potential site of entry of Common Anatolian languages into Anatolia… I have read some comments about how ‘impossible’ it was for steppe migrants and their language to ‘invade’ the more advanced cultures of Anatolia from the west, but it seems as ‘impossible’ as it was for Barbarians to invade the Roman Empire and impose their language as elites in certain regions. (And yes, we have at least one important weak political period among Middle Eastern cultures in the early 3rd millennium BC, similar to the period of the Fall of the Western Roman Empire).

Most likely Proto-Anatolian expansion in the North Pontic and Balkan area with Khvalynsk-Novodanilovka chieftains, including ADMIXTURE data from Wang et al. (2018).

If it is located somewhere more ‘central’ in the Greek Peninsula, then it could also be used to support the Anatolian nature of the controversial Pre-Greek (‘Pelasgian’) substrate. While we know that Greek (at least since Mycenaean) shows a strong Pre-Greek cultural and linguistic heritage (also reflected in its genetic continuity), the nature of that language is usually believed to be non-Indo-European, and Anatolian contacts are rather few and coincident with the Mycenaean period. I don’t think this sample can tell much about the Pre-Greek language, though, because – if it is really Neolithic, and comparing it with later Minoan and Mycenaean samples – it seems a clear outlier.

Heyd (2016): 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). The site in the south-west Balkans is Suvodol-Šuplevec, Northern Macedonia (FYROM).

If it is, however, related to later Yamna migrations after ca. 3000 BC (and, like the ‘Ukraine Eneolithic’ sample that is likely from Catacomb, it is classified as Neolithic just because it cannot be attributed to precise Helladic periods), then we may be in front of the first obvious Yamna migrants in Greece. If that is the case (which I doubt), the sample wouldn’t be so informative for PIE dialectal expansions, because by now it is evident that we will find steppe ancestry and R1b-Z2103 subclades accompanying Yamna migrants in the southern Balkans, and probably well into Mycenaean Greece.

NOTE. Whatever the case, I am sure that for those fond of absurd autochthonous continuity theories, as well as for anti-steppe conspirationists, this sample will be just another good way of arguing for anything, ranging from a rejection of the Middle PIE – Late PIE division, to a support for some mythic ancient autochtonous Proto-Graeco-Anatolian group, or maybe some ancient Graeco–Indo-Slavonic split, or whatever new dialectal stage one can invent to support the own genealogical fantasies…

So, if it actually is a Neolithic sample, let’s hope that it shows a clear R1b-M269 (xL23 or early L23) subclade distinct from those (likely Z2103) expanded later with Late PIE-speaking Yamna (and probably to be found among Mycenaeans), so that there can be no more place for ethnic fantasies.

Corded Ware culture origins: The Final Frontier


As you can imagine from my latest posts (on kurgan origins and on Sredni Stog), I am right now in the middle of a revision of the Corded Ware culture for my Indo-European demic diffusion model, to see if I can add something new to the draft. And, as you can see, even with ancient DNA on the table, the precise origin of the Corded Ware migrants – in spite of the imaginative efforts of the Copenhagen group to control the narrative – are still unknown.

Corded Ware origins

The main objects of study in Corded Ware origins are necessarily the region where the oldest Corded Ware vessels appeared, Lesser Poland, as well as the adjacent (traditionally considered Proto-Corded Ware regions) Volhynia, Podolia, and upper Dniester river basin. These are some relevant points, continuing where I left the Eneolithic steppe developments (following Szmyt 1999, Rassamakin 1999, Kadrow 2008, Furholt 2014):

Kadrow (2008). Cultural interactions around Carpathians at the beginnings of the 3rd millennium BC: 1 – Globular Amphora culture; 2 – Sofievka group of Trypillia culture; 3 – Funnel Beaker culture; 4 – Baden culture; 5 – Kostolac culture; 6 – Coţofeni culture; 7 – Cernavoda II culture; 8 – Yamnaya culture and Usatovo group of Trypillia culture (apud Kadrow, 2001).
  • More frequent contacts were seen ca. 3500-3000 BC, with an interaction showing multidirectional migrations of larger human groups in the centuries around 3000 BC, involving a significant part of the population of central-east Europe.
  • The easternmost area of the Funnel Beaker culture had become more Baden-like with the expansion of the Baden culture in its western area ca. 3300-2900 BC (with findings up to 2600 BC), and these younger groups with Baden features moved increasingly into the western part of Volhynia.
  • The influence of the neighbouring Trypillian culture is seen in the eastern parts of Volhynia, from ca. 3000 BC, either from a younger phase CII (cf. Troyaniv, Koshilivtsy, Brînzeni, Zhvaniets, or Vychvatintsy) or later groups (cf. Gorodsk, Kasperivtsy, Sofievka, Horodiştea-Folteşti, Usatovo).
  • In the forest-steppe zone, herding and hunting activities intensified, while agricultural traditions were preserved, as shown by the Sofievka, Kasperivtsy, and Gorodsk groups. From the end of the 4th millennium BC mobile parts of the late Trypillian populations moved to the steppe zone, absorbing more and more steppe elements; among others, cord ornamentation (in Vykhvatintsy, Troyaniv, and Gorodsk groups), pottery forms (Vykhvatintsy, which served as prototype for the Thuringian Apmphorae, dispersed along the Dniester river, too), flat burials with bodies in contracted position on the left or right side (Vykhvatintsy, reminding of Polgár culture different male-female position, and later Corded Ware burials, and also Lower Mikhailovka, under a mound without stone constructions). At the end of the Trypillia culture, its agricultural system collapsed completely.
Globular Amphorae culture „exodus” to the Danube Delta: a – Globular Amphorae culture; b – GAC (1), Gorodsk (2), Vykhvatintsy (3) and Usatovo (4) groups of Trypillia culture; c – Coţofeni culture; d – northern border of the late phase of Baden culture;red arrows – direction of Globular Amphora culture expansion; blue arrow – direction of „reflux” of Globular Amphora culture (apud Włodarczak, 2008, with changes).
  • Slash and burn techniques of agriculture – especially those practiced by Trypillian and Funnel Beaker populations – must have intensified effects of natural growth of humidity (ca. 3400-2400), increasing fluvial activities in west Ukrainian river valleys, and increasing deforestation processes, which favoured pastoralism and nomadisation of the settlement system, and a consequent change of the social structure
  • At the same time, Yamna communities expanded along the lower and central Danube to the west, while the populations of the late phase of the Baden culture took the opposite direction and reached as far as Kiev in the north-east, contributing to the culture of the Sofievka group.
  • Globular Amphora communities migrated from the north-west, from eastern Poland, towards the Danube Delta and as far as the Dnieper in the east, destroying the primary structures of the communities in the supposed cradle territories of the Corded Ware culture. These communities found refuge and conditions for further development in south-eastern margin zone of the Funnel Beaker culture territories, penetrating at first the upper parts of the loess uplands like typical Funnel Beaker sites, but on the margins of their range, and also on areas avoided by Funnel Beaker settlement agglomerations. They brought with them the so-called Thuringian amphora up to Lesser Poland, borrowed from the late Trypillian Usatovo group. This resulted in the Złota culture, which eventually gave rise to the A-Amphorae.

In the end, we are left with this information about the oldest CWC (Furholt 2014):

  • The earliest radiocarbon-dated groups associated with the Corded Ware culture come from new single graves from Jutland in Denmark and Northern Germany, ca. 2900 BC. This Early Single Grave culture is associated with the appearance of individual graves (some time after the decline of the megalithic constructions), composed of a small round barrow and a new gender-differentiated burial practice emphasising male individuals orientated west-east (with regional exceptions), combined with the internment with new local battle-axe types (A-Axe). However, there is no single type of burial or burial custom in Corded Ware:
    • In southern Sweden the prevailing orientation is north-east – south-west, and south-north, contrary to the supposed rule male individuals are regularly deposited on their left and females on their right side.
    • In the Danish Isles and north-eastern Germany, the Final Neolithic / Single Grave Period is characterized by a majority of megalithic graves, with only some single graves from typical barrows. In south Germany, west-east and collective burials prevail, while in Switzerland no graves are found.
    • In Kujawia (south-eastern Poland), Hesse (Germany), or the Baltic, west-east orientation and gender differentiation cannot be proven statistically.
Furholt (2014). Map of the Corded Ware regions of central Europe. The dark shading indicates those regions where Corded Ware burial rituals are present regularly
  • The oldest Corded Ware vessels (the A-Amphorae, which define the A-Horizon of the CWC) come probably from the Złota (or a related) group in Lesser Poland, where a mixed archaeological culture connecting Funnel Beaker, Baden, Globular Amphorae and Corded Ware appears ca. 2900-2600 BC. No cultural (typological) break is seen between earlier Globular Amphorae and the first Corded Ware Amphorae, but rather a continuum of traits and characteristics among the recovered vessels. This strengthens the connection of Corded Ware with Globular Amphorae peoples. The A-horizon expanded thus probably from Lesser Poland ca. 2800-2600, as seen in local contexts.
  • And of course we have a third way of defining Corded Ware individuals, which is the presence of herding, and thus a transition from hunter-gatherers to agropastoralists. This is how some Baltic Late Neolithic individuals with no archaeological data have been classified as members of the Corded Ware culture: Even though no cultural remains were extracted with the two ‘outlier’ individuals, their haplogroup and ancestry point to a direct origin in or around the steppe and forest-steppe region (yes, that risks circular reasoning).
Correspondence analysis of amphorae from the Złota-graveyards reveals that there is no typological break between Globular Amphorae and Corded Ware Amphorae, including ‘Strichbündelamphorae’ (after Furholt 2008)

Corded Ware peoples in genetics

So, no clear origin of Corded Ware migrants, a lot of data pointing to intense migrations and interaction among GAC, Trypillia and the western steppe population (remember Kristiansen’s ‘long-lasting GAC-CWC connection’, now ignored to favour their Yamnaya admixture™ concept), and also three ways of defining Corded Ware culture…

Maybe genetics can help:

Ukraine Neolithic cultures – mainly from Dereivka – show haplogroups R1b-V88, R1a1, and R1b-L754 (xP297, xM269), which is similar to the haplogroup distribution found in Ukraine Mesolithic, but apparently with an expanding group marked by haplogroup I2a2a1b1 (possibly I2a2a1b1b).

The first thing that stands out about Ukraine Eneolithic samples is that only two of them can be said to be really Ukraine Eneolithic (i.e. from “Sredni Stog”-related groups):

  • I5876 (Y-DNA R1a-Z93(Y3+), mtDNA U5a2a), from Alexandria, 4045-3974 calBCE (5215±20BP, PSUAMS-2832)
  • I4110 (mtDN AJ2b1), from Dereivka, 3634-3377 calBCE (4725±25 BP, UCIAMS-186349), J2b1

The other two samples are quite late, and in fact one of them is clearly too late (maybe from the Catacomb culture):

  • I5882 (mtDNA U5a2a), from Dereivka, 3264-2929 calBCE (4420±20BP, PSUAMS-2826)
  • I3499 (Y-DNA R1b-Z2103, mtDNA T2e), from Dereivka, 2890-2696 calBCE (4195±20BP, PSUAMS-2828)

Corded Ware samples from Mittnik et al. (2018) offer very wide radiocarbon dates, so it is unclear which of them may be the oldest one. Most of them cluster closely to the older Ukraine Eneolithic sample I5876, but also to later steppe_MLBA samples i.e. Sintashta, Potapovka, and especially Srubna and Andronovo). This points to a genetic continuity from Pre-Corded Ware to Classic and late Corded Ware peoples. Therefore, much like Khvalynsk-Yamna and apparently many other Neolithic cultures, these peoples did not really admix; at least not with the male population.

File modified by me from Mittnik et al. (2018) to include the approximate position of the most common ancestral components, and an identification of potential outliers. Zoomed-in version of the European Late Neolithic and Bronze Age samples. “Principal components analysis of 1012 present-day West Eurasians (grey points, modern Baltic populations in dark grey) with 294 projected published ancient and 38 ancient North European samples introduced in this study (marked with a red outline).

Lucky for us, even though the culture remains undefined, haplogroup R1a-Z645 seems like a unifying trait, as I said long ago, so we only have to wait for more samples to trace their origin. Nevertheless, it is clear that Corded Ware may not have been as genetically homogeneous as Khvalynsk, Yamna and Yamna-related cultures, further supporting its archaeological complexity:

  • Jagodno1 and Jagodno2 (Silesia), dated ca. 2800 BC, show haplogroup G? and I/J? – compatible with an origin of CWC in common with Trypillia (which shows 3 samples of haplogroup G2a2b2a, and one E) and Ukraine Neolithic (showing the expansion of I2a2a1b1 subclades).
  • I7272, from Brandýsek (Czech Republic), dated ca. 2900-2200 BC shows haplogroup I2a2a2 (compatible with an origin in Ukraine Neolithic peoples – this haplogroup is also found in Yamna Kalmykia and in the Yamna Bulgaria outlier, i.e. late western samples from the Early Yamna culture).

NOTE. This precise subclade is only present to date in Chalcolithic samples from Iberia, which points (possibly like the Esperstedt family) to local Central European haplogroups integrated in a mixed Proto-Corded Ware population. The upper subclade I2a2a is found in Neolithic samples from Iberia, the British Isles, Hungary (Koros EN, ALPc), and also south-east European Mesolithic and Neolithic samples.

  • RISE1, from Oblaczkowo (Greater Poland), ca. 2865-2578 BC, shows haplogroup R1b1.
  • The Esperstedt family samples have been analysed as R1a-M417 (xZ645), although the supposed ‘xZ645’ has not been confirmed – not even in the risky new Y-calls from Wang et al. (2018) supplementary materials.
Network analysis based on the quantitative occurrence of Corded Ware pottery forms, pottery ornamentation styles, tools,
weapons and ornaments as stated in Table 1, based on the catalogues given in Table 2, line thickness representing similarity

Maybe this heterogeneity is a problem of better defining the culture, but from what we can see the oldest CWC regions and the unifying ‘Corded Ware province’ – formed after ca. 2700 BC by Jutland and Northern Germany, the Netherlands, Saale, Bohemia, Austria and the Upper Danube regions – are for the moment not the most genetically homogeneous groups.

Homogeneity comes later – which we may tentatively identify with the expansion of the A-horizon from the northern Dnieper-Dniester and Lesser Poland area – , as seen around the Baltic (like the Battle Axe culture) with R1a-Z283 subclades, and around Sintashta (i.e. probably Abashevo – Balanovo) with R1a-Z93 subclades, which is compatible with the late spread of different Z645 groups (and potentially a unifying language) .


Human sacrifice as means of social control and power display in Upper Mesopotamia (early 3rd mill. BC)


Radical ‘royals’? Burial practices at Başur Höyük and the emergence of early states in Mesopotamia, by Hasset and Sağlamtimur, Antiquity (2018) 92:640-654.

Interesting excerpts:

The discovery of sacrificial burials attending a ‘royal’ burial in a cist tomb at Early Bronze Age Arslantepe in Anatolia (Frangipane 2006; Erdal 2012) has dramatically broadened the known range of social responses to the political upheaval of the early third millennium BC. Following the longstanding interpretation of human sacrifice at the Royal Cemetery of Ur just a few hundred years later (Woolley 1934), this raises new questions about the role of human sacrifice in processes of early state formation (Sürenhagen 2002; Croucher 2012). Power over the physical bodies of a population to the point of death has been associated with the hierarchical social structures that accompanied early state-formation processes across the globe (Watts et al. 2016). There is, however, considerable variation in the practice. Sacrifice can be employed variously to achieve spiritual, ritual, political, martial or even economic ends (see Bremmer 2007; Turchin 2016), and the role of human sacrifice in ancient Near Eastern burial practices remains unclear (Porter & Schwartz 2012).

“The mound site of Ba¸sur Höyük, with the archaeological plan of the Early Bronze Age cemetery. Graves are outlined in red, Uruk-period architecture in black. Each grid square is 10 × 10m.”

Wengrow draws an interesting distinction between “sacrificial” and “archival” ritual economies, using metal finds from the much wider context of the Eurasian Bronze Age (Wengrow 2011: 137). For Wengrow, the ‘sacrificial’ deposit of metal work, particularly in burial contexts, indicates a system of metal exchange that is most frequently found on the edges of more complex, centrally administrated urban exchange systems. Metalwork serves here to consolidate and display personal wealth rather than as a standardised commodity for equitable exchange. Wilkinson has highlighted the role of shifting economic modes in marking social change, observing such a transition in ritual-economic systems in the Early Bronze Age Trans-Caucasian sphere of influence that stretched from Anatolia to Iran (Wilkinson 2014). The bronze objects buried at Başur Höyük fall into a pattern of ritual deposits that clearly mark Early Bronze Age funerary rituals as locations for the communication of wealth and status (Săglamtimur & Massimino 2015). The importance of that display is not diminished by the presence of administrative artefacts such as the cylinder seals and ceramics marked with seal impressions that were also found inside the cist tomb. The material culture of the Early Bronze Age cemetery at Başur Höyük demonstrates connections to the Anatolian world, with clear Trans-Caucasian links similar to those found along the Euphrates, and also to the southern, urban networks of the Mesopotamian core.

The utility of such sacrificial gestures waned as other means of social control and power display were brought to bear by an administrated, ‘archival’ economy that did not require the sacrifice of its human subjects.(…) In the vacuum of political centralisation that followed the withdrawal of Uruk material culture in the Mesopotamian sphere, we see precisely the instability among smaller polities that would be expected to underlie the introduction of human sacrifice. In the vast administrative state systems that rose up in southern Mesopotamia in the next millennium, it disappears again from the archaeological record and it is not unreasonable to see in this pattern an implication for the value and economy of human life during the formation of early states.

Ebla’ first kingdom at its height c. 2340 BC. Hipothetical location of Armi depicted. The first Eblaite kingdom extended from Urshu in the north,1 to Damascus area in the south.2 And from Phoenicia and the coastal mountains in the west,3 4 to Tuttul,5 and Haddu in the east.6 The eastern kingdom of Nagar controlled most of the Khabur basin from the river junction with the Euphrates to the northwestern part at Nabada.7 Page 101. From Wikipedia.

Given the potential Anatolian names in Armi inscriptions (ca. 2500-2300 BC), this crucial period of political upheaval after the fall of Uruk-period Mesopotamian interregional networks and before the rise of new state system, i.e. in the early third millennium BC, is probably to be identified with the arrival of Anatolian speakers from the west.

Similar to the Early Indo-Aryan elites ruling over Hurrian-speaking Mitanni, it is possible that some Anatolian-speaking groups imposed their rule as elites (and thus their language) after this period of instability – at least in certain regions, as is obvious from the multilingualism and multiethnic situation found in the Old Assyrian tablets of Kaneš.


About Scepters, Horses, and War: on Khvalynsk migrants in the Caucasus and the Danube


dergachev-scepters-khavlynsk-horsesAbout two months ago I stumbled upon a gem in archaeological studies related to Proto-Indo-Europeans, the book О скипетрах, о лошадях, о войне: этюды в защиту миграционной концепции М.Гимбутас (On sceptres, on horses, on war: Studies in defence of M. Gimbutas’ migration concepts), 2007, by V. A. Dergachev, from the Institute of Cultural Heritage of the Moldavian Republic.

Dergachev’s work dedicates 488 pages to a very specific Final Neolithic-Eneolithic period in the Pontic-Caspian steppe, and the most relevant parts of the book concern the nature and expansion of horses and horse domestication, horse-head scepters, and other horse-related symbology – arguably the most relevant cultural signs associated with Proto-Indo-European speakers in this period.

I haven’t had enough time to read the whole book, but I have read with interest certain important chapters.

About Scepters

Typological classification

The genetic and chronological relationship of horse-head pommel-scepters is classified with incredible detail, to the extent that one could divide subregions among those cultures using them.

Scheme of regional distribution – chronological – typological development of the carved horse-head stone scepters.

Simplified conclusions of this section include (emphasis mine):

  1. The [horse-head pommel-]scepters arose originally in the depth of the Khvalynsk culture. Following the now well-known finds, they are definitely related to those of the Middle Volga group.
  2. horse-head-pommel-scepters-distribution
    General scheme of genetic and chronological development of carved scepters by visual assessment of morphological details.
  3. In their next modifications, these scepters continued to evolve and develop into the area of the Khvalynsk culture in its latest stages, and possibly later.
  4. Simultaneously, with the same modifications, these scepters “are introduced” into common usage in the Novodanilovka culture, which in its spread by one wing was in contact and interspersed immediately with the area of Khvalynsk remains; and on the other hand, far in the south – in the Pre-Kuban and Ciscaucasian regions – within the range of the Domaikopska culture; and in the west – in the Carpathian – Post-Kuban – with the areas of early agricultural cultures Cucuteni A – Trypillia B1, Gumelnița-Karanovo VI.
  5. The simultaneous presence in the areas of the Ciscaucasian, Carpatho-Danubian, and especially Novodinilovka cultures, whose carriers continue the Khvalynian traditions of making stone scepters, and the scepters themselves (in their non-functional implication in the local cultural environment), all definitely allow us to view these findings as imported Novodanilovka objects.
Schematic depiction of the spread of horse-head scepters in the Middle Eneolithic. See a full version with notes here.

Cultural relevance of scepters

The text goes on to make an international comparison of scepters and their relevance as a cultural phenomenon, with its strong symbolic functions as divine object, its use in times of peace, in times of war, and in a system of ritual power.

Restoration of V. A. Dergachev: a) model for restoration – Paleolithic and Neolithic wands; b) the expected appearance of the Eneolithic scepter on the handle with a coupling (according to Dergachev 2007).
Especially interesting is the section dedicated to Agamemnon’s scepter in the Iliad, one of the oldest Indo-European epics. Here is an excerpt from Illiad II.100-110 (see here the Greek version) with the scepter’s human and divine genealogy:

Then among them lord Agamemnon uprose, bearing in his hands the sceptre which Hephaestus had wrought with toil. Hephaestus gave it to king Zeus, son of Cronos, and Zeus gave it to the messenger Argeïphontes; and Hermes, the lord, gave it to Pelops, driver of horses, and Pelops in turn gave it to Atreus, shepherd of the host; and Atreus at his death left it to Thyestes, rich in flocks, and Thyestes again left it to Agamemnon to bear, that so he might be lord of many isles and of all Argos.

About the horse

His studies on horse remains show an interesting, detailed quantitative and statistical approach to the importance and (cultural and chronological) origin of horses (and likely horse domestication) in each culture.

Although the part on horse remains is probably a bit outdated today, after many recent studies of Eneolithic steppe sites (see here one example), it still shows the relative distribution of horse bone remains among different steppe cultures, which is probably similar to what could be reported today:

Territorial distribution of horse remains in the Middle Eneolithic period. Absolute and relative numbers.

Even more interesting is the relationship of the distribution of horse remains with archaeological complexes and horse-related symbols. Some excerpts from the conclusions of this section:

  1. Accounting and analysis of archeo-zoological and archaeological data proper for a horse for a vast area from the Tisza and the Middle Danube to the Caucasus and the Urals (which includes the main cultures of the western agricultural, Caucasian, and Eastern European cultural zones) clearly points to the eastern cultural zone as a zone of the originally the most important social significance of a horse as the only possible zone of the earliest domestication, horseback riding and all-round use of a horse. In relation to the eastern, the western land – the ancient Carpatho-Danubian or the Caucasian cultural zones – are secondary and subordinate to the first on the phenomenon under consideration.
  2. horse-symbols
    Horse-shaped hanger-amulets made of bone.
  3. The first quantitative leap in the manifestation of the remnants of a horse, marking itself and the first qualitative changes in the social status of this animal, is due mainly to the Middle Volga culture of the developed Neolithic of the Middle Volga region (in part, the Southwest Urals), which, accordingly, determine the cultural context, time and geographic region – or, the initial, single and main epicenter of the process of taming and domestication of a horse.
  4. On the one hand, the subsequent substantial increase in the number of horse remnants, and, on the other, the wide inclusion of the horse in cults, rituals, funerary rituals (horse pendants, ornamented metacarpus, horse bones, sacrificial altars) in the Samara culture of the Early Eneolithic of the same region definitely indicates the continuing increase in the social significance of this species of animal, which was most likely expressed in the final design of a specialized horse breeding culture and, accordingly, in a wide range of applications using a horse for riding. At the same time, we can observe the beginning of the transfer of the already domesticated horse from the original historical and geographic epicenter to other cultures of the eastern cultural zone and, in part, the cultures closest to the periphery of this zone, into the western agricultural zone (Bolgrad-Aldeni P, Pre-CuCuteni-Trypillya A) .
  5. expansion-horse-steppe
    Schematic depiction of cultures and regional-chronological distribution of percentage of horse remains. (Depicted are arrows from Middle Volga and Samara culture to the rest)
  6. Middle Eneolithic – early stages. One of the leading places in the remnants of the horse is in the Middle Volga region, the Khvalynsk culture. Genetically related to the Samara, the Khvalynsk I culture preserves the traditions of the ritual, cultural meaning, the treatment of the image of a horse in funerals (altars, horse bones, funerary rituals). But, At the same time, it is in this precise culture that the image of the horse, included in the social symbolism (horse-head pommel-scepter), for the first time it acquires a special, maximum social significance. That is why the appearance and subsequent widespread distribution of the social symbols in Novodanilovka-type objects can definitely be considered as another qualitative leap in the social significance of a horse – its use for military purposes for close and distant expeditions. And such an interpretation is fully confirmed from the analysis of Novodanilovka-type objects, which is the subject of discussion.
  7. Judging by the osteological data and the typological evolution of the horse-head scepters, the Khvalynian culture and remains of the Novodanilovka type are already associated with the relatively widespread and intensive findings of domesticated horses in various areas of the eastern cultural zone (semi-desert regions of the Lower Volga and the Caspian region – Khvalynsk culture, forest-steppe and steppe from the Volga to the Dnieper – Sredni Stog, Repin cultures), and the western – agricultural (Gumelnitsa, Cucuteni A-Tripolye Bl), and the Caucasus (Pre-Maykop) zones, where, however, the horse played a very modest role.

    Schematic depiction of cultures and regional-chronological distribution of zooarchaeological and ritual data on horses. (Shadowed are from top to bottom the Middle Volga, Samara, Khvalynsk, and Novodanilovka; in bold, other percentages of unrelated cultures: e.g. to the left of Khvalynsk and Novodanilovka, Sredni Stog with 29.65% overall horse bone remains, but 0% of horse symbolism)
  9. From the functional point of view, according to the sum of the data, there is no reason to doubt that in the eastern zone the horse is already present in the Late Neolithic period. Since its domestication and the emergence of a specialized horse breeding, it has been also widely used for meat, milk and dairy products (including the traditional hippace tradition of the later Scythians), and since the beginning of the early Eneolithic for transport and for riding purposes. Another thing is the horse as a means of war, a means of distant travel and expansion. The beginning of the use of a horse for these purposes, in the opinion of the author, is determined by the appearance of social symbolism in the form of horse-head scepters, and is most fully reflected in the memories of the Khvalynsk culture and, in particular, the Novodanilovka type. Concerning western or Caucasian cultural zones related to Khvalynsk, the horse is thought to have been linked to the eastern region, used mainly for riding, as a means of transport and for communication, which, however, does not exclude its use for meat.

These are the main conclusions-interpretations, suggesting the analysis and archaeological and other sources containing information about the horse. And as for our pommel-scepters, then, as can be seen from these sources, the main thing is that the culture of the Middle Volga region, according to all the data, definitely accumulates in itself the longest traditions associated with the gradual increase of social significance of the horse. And if so, this circumstance motivates the possibility or necessity of appearing in the environment of the bearers of this culture of unique signs-symbols that carry within themselves or reflect the image of this animal as an extremely significant social reality. The revealed and characterized quality, as a matter of fact, fill or open by themselves the hypothetical elements we have previously identified, the meanings of that particularity, folded in the social sign-symbol, in our case – the horse-head-shaped scepter.

Archaeological sites with objects (signs-symbols) related to horses. Horse-head scepters included in other maps are excluded from this one (notice the conspicuous absence of such objects in Sredni Stog and neighbouring North Pontic regions).

The relevance of Dergachev’s work

As you certainly know by now if you are a usual reader of this blog, there were two other seminal publications that same year correcting and expanding Gimbutas’ model:

Each one of these works taken independently (especially the books) may give a different version of Proto-Indo-European migrations; Anthony and Dergachev are heirs of Gimbutas’ simplistic kurgan-based model, and of other previous, now rejected ideas, and they reflect them whenever they don’t deal with first-hand investigation (and even sometimes when interpreting their own data). Taken together – and especially in combination with recent genetic studies – , though, they describe a clearer, solider model of how Proto-Indo-Europeans developed and expanded.

Distribution of horse-head scepters, according to Dergachev, Sorokin (1986).

Anthony’s publication overshadowed the importance of Dergachev’s work for the English-speaking world – and by extension for the rest of us. However, V. A. Dergachev’s updated study of his previous work on steppe cultures shows the right, thorough, and diligent way of describing the expansion of early Khvalynsk-Novodanilovka chieftains with the horse and horse symbolism into the Caucasus and the Lower Danube (like the seminal work of Harrison & Heyd 2007 described the expansion of Yamna settlers with East Bell Beakers, culturally opposed to Corded Ware and to the Proto-Beakers). On the other hand, Anthony’s broad-brush, superficial description of thousands of years of potential Indo-European-speaking peoples gave a migration picture that – although generally right (like radiocarbon-based Iberian origin of the Bell Beaker culture was right) – was bound to be wrong in some essential details, as we are seeing in archaeology and genetics.

NOTE. As I have said before, Anthony’s interpretations of Sredni Stog culture representing a sort of ‘peasants’ under the rule of Novodanilovka chiefs was based on old theories of Telegin, who changed his mind – as did the rest of the Russian school well before the publication of Dergachev’s book, considering both as distinct cultural phenomena. Anthony selected the old interpretation, not to follow a Gimbutas / Kristiansen model of Sredni Stog being Indo-European and expanding with GAC into Corded Ware (because, for him, Corded Ware peoples were originally non-Indo-European speakers): he seems to have done it to prove that Proto-Anatolian traveled indeed through the North Pontic area, i.e. to avoid the regional ‘gap’ in the maps, if you like. Then with the expansion of Repin over the area, Sredni Stog peoples would have been absorbed. With genetic investigation, as we know, and with this kind of detailed archaeological studies, the traditional preference for “large and early” IE territories – proper of the mid-20th century – are no longer necessary.

Anthony (2007): “Steppe and Danubian sites at the time of the Suvorovo-Novodanilovka intrusion, about 4200-3900 BC.”

Steppe Eneolithic

We already had in 2016 a Samara hunter-gatherer sample dated ca. 5600 BC, representative of EHG ancestry, of haplogroup R1b1a. We also had three early Khvalynsk samples from Samara Eneolithic dated ca. 4600 BC, with a drift towards (what we believe now is) a population from the Caucasus, showing haplogroups Q1a, R1a1(xM198), and R1b1a, the last one described in its paper as from a high-status burial, similar to high-status individuals buried under kurgans in later Yamna graves (of R1b-L23 lineages), and therefore likely a founder of an elite group of patrilineally-related families, while the R1a1 sample showed scarce decoration, and does not belong to the M417 lineage expanded later in Sredni Stog or Corded Ware.

In 2017 we knew of the Ukraine_Eneolithic sample I6561, from Alexandria, of a precise subclade (L657) of haplogroup R1a-Z93, dated ca. 4000 BC, and likely from the Sredni Stog (or maybe Kvitjana) culture. This sample alone makes it quite likely that the expansion of R1a-Z645 subclades happened earlier than expected, and that it was associated with movements along forest-steppe cultures, most likely along the Upper Dniester or Dnieper-Dniester corridor up to the Forest Zone.

We have now confirmation that Khvalynsk samples from the Yekaterinovka Cape settlement ca. 4250-4000 BC were reported by a genetic lab (to the archaeological team responsible) as being of R1b-L23 subclades, although the precise clades (reported as P312 and U106) are possibly not accurate.

NOTE. Curiously enough, and quite revealing for the close relationship of scepters to the ritual source of power for Khvalynsk chieftains (political and/or religious leaders), the scepter found in the elite burial 45 of the Ekaterinovka cape (a riverine settlement) shows a unique zoomorphic carving, possibly resembling a toothed fish or reptile, rather than the most common horse-related motifs of the time.

With Wang et al. (2018), a real game-changer in the Khvalynsk – Sredni Stog (and also in the Yamna/Bell Beaker – Corded Ware) opposition, we also know that two Steppe Eneolithic samples from the Northern Caucasus Piedmont, dated ca. 4300-4100 BC, show haplogroup R1b1. Although its direct connection to the expansion of early Khvalynsk with horse-related symbolism is not clear from the archaeological information shared (none), this is what the paper has to say about them:

The two distinct clusters are already visible in the oldest individuals of our temporal transect, dated to the Eneolithic period (~6300-6100 yBP/4300-4100 calBCE). Three individuals from the sites of Progress 2 and Vonjuchka 1 in the North Caucasus piedmont steppe (‘Eneolithic steppe’), which harbor Eastern and Caucasian hunter-gatherer related ancestry (EHG and CHG, respectively), are genetically very similar to Eneolithic individuals from Khalynsk II and the Samara region19, 27. This extends the cline of dilution of EHG ancestry via CHG/Iranian-like ancestry to sites immediately north of the Caucasus foothills.

In contrast, the oldest individuals from the northern mountain flank itself, which are three first degree-related individuals from the Unakozovskaya cave associated with the Darkveti-Meshoko Eneolithic culture (analysis label ‘Eneolithic Caucasus’) show mixed ancestry mostly derived from sources related to the Anatolian Neolithic (orange) and CHG/Iran Neolithic (green) in the ADMIXTURE plot (Fig. 2C). While similar ancestry profiles have been reported for Anatolian and Armenian Chalcolithic and Bronze Age individuals20, 23, this result suggests the presence of the mixed Anatolian/Iranian/CHG related ancestry north of the Great Caucasus Range as early as ~6500 years ago.

On the specific burials, we have e.g. the recent open access paper New cases of trepanations from the 5th to 3rd millennia BC in Southern Russia in the context of previous research: Possible evidence for a ritually motivated tradition of cranial surgery?, by Gresky et al. J Am Phys Anthropol (2016):

During the late 5th millennium BC, cultural groups of the Eneolithic occupied the northern circumpontic area and the areas between the North Caucasus and the Lower Volga. For the first time, individual inhumations were placed below low burial mounds (Rassamakin, 2011). During the 4th millennium BC, the area split into two cultural spheres. In the northern steppe area communities continued with the burial practice of crouched inhumations below low mounds, with this culturally transforming into the early Pit Grave culture. In contrast, in the Caucasian foothill zone and the neighbouring steppe, the Majkop-Novosvobodnaya culture emerged (Kohl and Trifonov, 2014). Similarly, during the 3rd millennium BC, two cultural spheres influenced the area: The North Caucasian Culture dominated the Caucasian foothills for the next five centuries, while in the steppe area between the Lower Don and the Caucasus, regional groups of the Catacomb Culture existed side-by-side.

Burials of the Eneolithic epoch (late 5th millennium BC)

The oldest group of individuals with trepanations are found in the North Caucasian variant of the late circumpontic Eneolithic and date to the last third of the 5th millennium BC (Korenevsky, 2012). Burials of this epoch are inhumations in shallow pits, chiefly without burial goods, but covered with large quantities of red ochre. Of special interest is a collective burial of seven individuals from VP 1/12, who were interred together in a secondary burial ritual. The sites of Tuzluki, Mukhin, Voinuchka, Progress, and Sengileevskii all belong to this period.

An EHG and a Caucasus ‘clouds’ have been drawn, leaving Pontic-Caspian steppe and derived groups between them.See the original file here.

Without the datasets to test different models, you can only imagine what is happening with the processed, secondary data we have. The position of Eneolithic Steppe cluster in the PCA (probably Khvalynsk-related peoples already influenced by the absorbed, previous Caucasus population), as well as other potential Caucasus groups intermediate between Steppe Maykop and Caucasus Maykop (as suggested by other ancient and modern Caucasus samples), may indicate that Yamna is between Khvalynsk and such intermediate Caucasus populations (as the source of the additional CHG-related ancestry) and – as the paper itself states – that it also received additional EEF contribution, probably from the western cultures absorbed during these Khvalynsk-Novodanilovka migrations (or later during Khvalynsk/Repin migrations).

Also interpreted in light of these early Khvalynsk-Novodanilovka migrations of horse riding chieftains (and their close contacts with the Caucasus), you can clearly see where the similar CHG-like contribution to Ukraine Eneolithic and other North Pontic forest-steppe cultures (which later contributed to Proto-Corded Ware peoples) must have come from. The simplistically reported proportions of EHG:CHG:EEF ancestry might be similar in many of these groups, but the precise origin and evolution of such ancestral components is certainly not the same: statistical methods will eventually show this, when (and if) we have many more samples, but for the moment Y-DNA is the most obvious indicator of such differences.

There was no steppe people speaking a steppe language AKA immutable Proto-Indo-European: the glottochronological models spanning thousands of years are not valid for the steppe, just as they are not valid for an Anatolian homeland, nor for a Caucasus homeland. The actual cultural-historical early Sredni Stog – Khvalynsk community, formed earlier than ca. 5000 BC, is a thousand years older than the expansion of Khvalynsk with the horse, and some two thousand years older than the expansion of Khvalynsk-Repin/Early Yamna migrants (see here for the latest genetic research).

What lies between the formation of that early Eneolithic cultural-historical community, and what we see in archaeology and genetics in Middle and Late Eneolithic steppe cultures, is the radical differentiation of western (Ukraine Eneolithic, mainly forest-steppe) and eastern (Samara and Khvalynsk/Repin, mainly steppe) cultures and peoples, i.e. precisely the period of differentiation of an eastern, Proto-Indo-Hittite-speaking early Khvalynsk community (that expanded with the horse and horse-related symbols) from a western, probably Early Proto-Uralic speaking community of the North Pontic forest-steppe cultural area.

NOTE. I am not against a Neolithic ‘steppe’ language. But this steppe language was spoken before and/or during the first Neolithisation wave, and should be associated with Indo-Uralic. If there was no Indo-Uralic language, then some communities would have developed Early Proto-Indo-European and Early Proto-Uralic side by side, in close contact to allow for dozens of loanwords or wanderwords to be dated to this period (where, simplistically, PIH *H corresponds to EPU *k, with some exceptions).

Map of a) steppe – forest-steppe border during the Eneolithic in the Pontic-Caspian region and b) the border today, showing a more limited steppe zone in the North Pontic area (reason for the specific ways of expansion of horse-related cultures and horse-related nomadic pastoralism during the Eneolithic).

The convergence that we see in PCA and Admixture of Yamna and the earliest Baltic LN / Corded Ware ‘outlier’ samples (if not directly related exogamy of some Baltic LN/CWC groups with Yamna migrants, e.g. those along the Prut), must be traced back to the period of genetic drift that began precisely with these Khvalynsk-Novodanilovka expansions, also closely associated with populations of the Caucasus, thus bringing North Pontic forest-steppe cultures (probably behind Proto-Corded Ware peoples) nearer to Khvalynsk, and both by extension to Yamna.

We have seen this problem arise in Bell Beaker samples expanding all over Europe, turning from a fully Yamnaya-like population to something else entirely in different regions, from more EEF-like to more CWC-like, sharing one common trait: Y-DNA. We are seeing the same happen with Balkan groups and Mycenaeans, with Old Hittites, and with steppe MLBA from Andronovo peoples expanding over Central and South Asia, and we know that patrilineal clans and thus Y-chromosome bottlenecks were common after Neolithisation, especially with nomadic pastoralist steppe clans (and probably also with many previous population expansions).

Steppe Eneolithic peoples were thus no different to other previous and posterior expanding groups, and ancestry is going to be similar for people living in neighbouring regions, so Y-DNA will remain the essential tool to distinguish different peoples (see here a summary of Proto-Indo-Europeans expanding R1b-L23).

We are nevertheless still seeing “R1b zombies” (a quite appropriate name I read on Anthrogenica) still arguing for a Western European origin of R1b-L23 based on EEF-like ancestry and few steppe-related contribution found in Iberian Bell Beakers (read what David Reich has to say on this question); and “OIT zombies” still arguing for IVC representing Proto-Indo-European, based on Iran_N ancestry and the minimal steppe ancestry-related impact on certain ancient Asian cultures, now partly helped by “Caucasus homeland zombies” with the new PIE=CHG model; apart from many other pet theory zombies rising occasionally from their graves here and there. Let’s hope that this virus of the undead theories does not spread too strongly to the R1a-Indo-European association, when the official data on Khvalynsk, West Yamna, and Yamna Hungary come out and show that they were dominated by R1b-L23 lineages.

Because we need to explore in detail the continuation of Khvalynsk-related (potential Proto-Anatolian) cultures in the Lower Danube and the Balkans, e.g. from Cernavoda I to Cernavoda III, then maybe to Ezero, and then to Troy; as well as the specific areas of Late Indo-European expansions associated with Early Yamna settlers turning into Bell Beakers, Balkan EBA, and Steppe MLBA-associated cultures. There is a lot of work to do on proper definition of Bronze Age cultures and their potential dialects, as well as convergence and divergence trends, and not only of Indo-European, but also of Uralic-speaking communities derived from Corded Ware cultures.

If we let the narratives of the 2000s in Genetics (in combination with the 1960s in Archaeology) dominate the conversation, then a lot of time will be absurdly lost until reality imposes itself. And it will.

The future of the Reich Lab’s studies and interpretations of Late Indo-European migrations


Short report on advances in Genomics, and on the Reich Lab:

Some interesting details:

  • The Lab is impressive. I would never dream of having something like this at our university. I am really jealous of that working environment.
  • They are currently working on population transformations in Italy; I hope we can have at last Italic and Etruscan samples.
  • It is always worth it to repeat that we are all the source of multiple admixture events, many of them quite recent; and I liked the Star Wars simile.
  • Also, some names hinting at potential new samples?? Zajo-I, Chanchan, Gurulde?, Володарка (Ukraine – medieval?), Autodrom, Облевка, Кресты, Кудуксай (Ural region, palaeo-metal?), Золкут, etc.
Ancient DNA sample bag?

On the bad aspect, they keep repeating the same “steppe ancestry” meme (in the featured image above, or the one below). I know this is the news report (i.e. science communication), not exactly the Reich Lab, but these maps didn’t appear out of the blue.

Steppe ancestry distribution in Europe, according to PBS.

Interesting for future interpretations is the whiteboard behind David Reich’s back (apparently they like to keep relevant information on whiteboards…):

Whiteboard behind David Reich’s back (at his office?).

It seems that while the Copenhagen group will still be bound (see here) by the Gimbutas/Kristiansen starting point, the Reich Lab will remain bound by Anthony’s selection of Ringe’s (2002) glottochronological model, and they will try to make genomic data fit in with it.

In fact, the whiteboard doesn’t even include Ringe’s link of Germanic with Italo-Celtic, which could maybe hint at Anthony’s recent change of heart? (i.e. Yamna Hungary -> Corded Ware). That would mean still less Linguistics (if glottochronology can be called that), and more Archaeology…

Image from Anthony & Ringe (2015). “The Proto-Indo-European homeland, with migrations outward at about 4200 BCE (1), 3300 BCE (2), and 3000 BCE (3a and 3b). A tree diagram (inset) shows the pre-Germanic split as unresolved. Modified from Anthony (2013).”

I don’t know why university labs need to do this: To select the linguistic model preferred by a single archaeologist, which happens to be the lead archaeologist of the group, and then try to make genetic data agree again and again with that model. I guess it is a strategic question, and has to do with granting continued contacts with archaeological sites, and access to samples from them?

I understand none of them will try to learn ancient languages, too much work probably. But, wouldn’t it have been more scientifish, at least, to depart from, say, three or four reasonable potential linguistic models (that is, from Indo-Europeanists), and from there discuss the best potential fits for the current genomic data in each paper?

This is, for example, how the Heyd (archaeologist) + German/Spanish Indo-Europeanist schools would look like:

Yamnaya expansion coupled with Meid’s (1975) description of three stages of Proto-Indo-European development (as interpreted by Adrados 1998) and depiction of Heyd’s proposal of Yamna expansion.

Wouldn’t you say it could have fitted the statistical and Y-DNA data seamlessly, in contrast to Gimbutas/Trager (i.e. Kristiansen today), or to Anthony/Ringe?

NOTE. I would say the mainstream German school follows Meid’s (1975) three-stage theory coupled with Dunkel’s (e.g. 1997) nomenclature. The Spanish school follows Adrados, who has repeated ad nauseam that he was the first to mention the three-stage theory in conferences and papers previous to and coincident with Meid’s proposal (see his latest JIES article, a paper available in Scribd). In any case, Spanish and German scholars have been working hand in hand in accepting and developing a general linguistic model similar to the one above.

Archaeological theories like those of Heyd or Mallory for Yamna and Bell Beaker (in contrast to Kristiansen or Anthony), and Prescott and Walderhaug for Bell Beaker and Germanic (contrasting with Kristiansen and Iversen) are compatible with this German/Spanish model.

The French school is non-existent on the homeland matter, Italian scholars seem to be behind even in the description of Anatolian as archaic (probably related to the general wish to have Latin as derived from Vergil’s Troy), Russian scholars are still working with Nostratic and Mesolithic expansions, and Leiden, as the leading IE publisher worldwide today, is full of very different ‘divos’, each with his own pet theory (some obviously agreeing with the German/Spanish model; and especially interesting is that some of them are strong supporters of an Indo-Uralic proto-language).

The English-speaking world, on the other hand, has seen the most varied models being either proposed or translated into its language, with the most popular ones being those publicized by archaeologists (Winfred P. Lehmann being one of the noteworthy exceptions), which may explain why for some people (archaeologists or geneticists) linguistics seems more like a game. It is to be assumed that these same people haven’t taken a look at the dozens of genetic papers published to date – and hundreds of archaeological papers using a bit of linguistics to support their models – , and how wrong they have all been in their interpretations, or else they would realize that genomics does (sadly) not really look like a serious discipline at all right now among most linguists, and among many archaeologists either…

Thus, instead of comparing the main theories on Proto-Indo-European (i.e. linguistics->archaeology->genetics), which would have offered the most stable framework to assess potential prehistoric ethnolinguistic identifications, they keep using a single, simplistic language tree liked by an archaeologist, and trying to fit genetic data to it, while also adapting archaeology to genetics, i.e. genetics->archaeology->linguistics; which, as you can imagine, is not going to convince any linguist.

Especially disappointing is that the world’s leading genetic lab still relies on a marginal proposal based on glottochronology, the homeopathy of linguistics… At least in that regard everyone should know better by now.

Also, they keep interacting with the wrong audience: instead of trying to engage linguists into the real homeland and dialectal quest, to keep Genomics a serious discipline among academics, they tend to discuss with politically- or racially-motivated people, which is probably also in line with strategic decisions.

In the example below, we see the main author of their recent paper on Indo-Iranian migrations seeking once again interaction, this time through “news” promoted by Hindu nationalist bigots, so that – even if that makes them look more neutral in the eyes of those who may allow access to Indian samples – , in the end, we see in genomics a fictitious revival of the “AIT vs. OIT debate” dead long ago in linguistics and archaeology (anywhere but in India).

Pretty disappointing to see these trends; so much effort and time invested in futile discussions and infinitely reworked doomed glottochronological or 19th-century models, when it is the fine-scale population structure of expanding Yamna peoples what we should be discussing now, and thus Late PIE dialectalisation with offshoots Afanasevo, East Bell Beaker, Balkan Bronze Age, and Sintashta/Potapovka; as well as Corded Ware evolution in Uralic-speaking territory.
