Yamnaya ancestry: mapping the Proto-Indo-European expansions


The latest papers from Ning et al. Cell (2019) and Anthony JIES (2019) have offered some interesting new data, supporting once more what could be inferred since 2015, and what was evident in population genomics since 2017: that Proto-Indo-Europeans expanded under R1b bottlenecks, and that the so-called “Steppe ancestry” referred to two different components, one – Yamnaya or Steppe_EMBA ancestry – expanding with Pro-Indo-Europeans, and the other one – Corded Ware or Steppe_MLBA ancestry – expanding with Uralic speakers.

The following maps are based on formal stats published in the papers and supplementary materials from 2015 until today, mainly on Wang et al. (2018 & 2019), Mathieson et al. (2018) and Olalde et al. (2018), and others like Lazaridis et al. (2016), Lazaridis et al. (2017), Mittnik et al. (2018), Lamnidis et al. (2018), Fernandes et al. (2018), Jeong et al. (2019), Olalde et al. (2019), etc.

NOTE. As in the Corded Ware ancestry maps, the selected reports in this case are centered on the prototypical Yamnaya ancestry vs. other simplified components, so everything else refers to simplistic ancestral components widespread across populations that do not necessarily share any recent connection, much less a language. In fact, most of the time they clearly didn’t. They can be interpreted as “EHG that is not part of the Yamnaya component”, or “CHG that is not part of the Yamnaya component”. They can’t be read as “expanding EHG people/language” or “expanding CHG people/language”, at least no more than maps of “Steppe ancestry” can be read as “expanding Steppe people/language”. Also, remember that I have left the default behaviour for color classification, so that the highest value (i.e. 1, or white colour) could mean anything from 10% to 100% depending on the specific ancestry and period; that’s what the legend is for… But, fere libenter homines id quod volunt credunt.


  1. Neolithic or the formation of Early Indo-European
  2. Eneolithic or the expansion of Middle Proto-Indo-European
  3. Chalcolithic / Early Bronze Age or the expansion of Late Proto-Indo-European
  4. European Early Bronze Age and MLBA or the expansion of Late PIE dialects

1. Neolithic

Anthony (2019) agrees with the most likely explanation of the CHG component found in Yamnaya, as derived from steppe hunter-fishers close to the lower Volga basin. The ultimate origin of this specific CHG-like component that eventually formed part of the Pre-Yamnaya ancestry is not clear, though:

The hunter-fisher camps that first appeared on the lower Volga around 6200 BC could represent the migration northward of un-admixed CHG hunter-fishers from the steppe parts of the southeastern Caucasus, a speculation that awaits confirmation from aDNA.

The typical EHG component that formed part eventually of Pre-Yamnaya ancestry came from the Middle Volga Basin, most likely close to the Samara region, as shown by the sampled Samara hunter-gatherer (ca. 5600-5500 BC):

After 5000 BC domesticated animals appeared in these same sites in the lower Volga, and in new ones, and in grave sacrifices at Khvalynsk and Ekaterinovka. CHG genes and domesticated animals flowed north up the Volga, and EHG genes flowed south into the North Caucasus steppes, and the two components became admixed.

To the west, in the Dnieper-Dniester area, WHG became the dominant ancestry after the Mesolithic, at the expense of EHG, revealing a likely mating network reaching to the north into the Baltic:

Like the Mesolithic and Neolithic populations here, the Eneolithic populations of Dnieper-Donets II type seem to have limited their mating network to the rich, strategic region they occupied, centered on the Rapids. The absence of CHG shows that they did not mate frequently if at all with the people of the Volga steppes (…)

North-West Anatolia Neolithic ancestry, proper of expanding Early European farmers, is found up to border of the Dniester, as Anthony (2007) had predicted.

2. Eneolithic

From Anthony (2019):

After approximately 4500 BC the Khvalynsk archaeological culture united the lower and middle Volga archaeological sites into one variable archaeological culture that kept domesticated sheep, goats, and cattle (and possibly horses). In my estimation, Khvalynsk might represent the oldest phase of PIE.

(…) this middle Volga mating network extended down to the North Caucasian steppes, where at cemeteries such as Progress-2 and Vonyuchka, dated 4300 BC, the same Khvalynsk-type ancestry appeared, an admixture of CHG and EHG with no Anatolian Farmer ancestry, with steppe-derived Y-chromosome haplogroup R1b. These three individuals in the North Caucasus steppes had higher proportions of CHG, overlapping Yamnaya. Without any doubt, a CHG population that was not admixed with Anatolian Farmers mated with EHG populations in the Volga steppes and in the North Caucasus steppes before 4500 BC. We can refer to this admixture as pre-Yamnaya, because it makes the best currently known genetic ancestor for EHG/CHG R1b Yamnaya genomes.

From Wang et al (2019):

Three individuals from the sites of Progress 2 and Vonyuchka 1 in the North Caucasus piedmont steppe (‘Eneolithic steppe’), which harbour EHG and CHG related ancestry, are genetically very similar to Eneolithic individuals from Khvalynsk II and the Samara region. This extends the cline of dilution of EHG ancestry via CHG-related ancestry to sites immediately north of the Caucasus foothills

This map corresponds roughly to the map of Khvalynsk-Novodanilovka expansion, and in particular to the expansion of horse-head pommel-scepters (read more about Khvalynsk, and specifically about horse symbolism)

NOTE. Unpublished samples from Ekaterinovka have been previously reported as within the R1b-L23 tree. Interestingly, although the Varna outlier is a female, the Balkan outlier from Smyadovo shows two positive SNP calls for hg. R1b-M269. However, its poor coverage makes its most conservative haplogroup prediction R-M343.

The formation of this Pre-Yamnaya ancestry sets this Volga-Caucasus Khvalynsk community apart from the rest of the EHG-like population of eastern Europe.

Anthony (2019) seems to rely on ADMIXTURE graphics when he writes that the late Sredni Stog sample from Alexandria shows “80% Khvalynsk-type steppe ancestry (CHG&EHG)”. While this seems the most logical conclusion of what might have happened after the Suvorovo-Novodanilovka expansion through the North Pontic steppes (see my post on “Steppe ancestry” step by step), formal stats have not confirmed that.

In fact, analyses published in Wang et al. (2019) rejected that Corded Ware groups are derived from this Pre-Yamnaya ancestry, a reality that had been already hinted in Narasimhan et al. (2018), when Steppe_EMBA showed a poor fit for expanding Srubna-Andronovo populations. Hence the need to consider the whole CHG component of the North Pontic area separately:

NOTE. Fits for WHG + CHG + EHG in Neolithic and Eneolithic populations are taken in part from Mathieson et al. (2019) supplementary materials (download Excel here). Unfortunately, while data on the Ukraine_Eneolithic outlier from Alexandria abounds, I don’t have specific data on the so-called ‘outlier’ from Dereivka compared to the other two analyzed together, so these maps of CHG and EHG expansion are possibly showing a lesser distribution to the west than the real one ca. 4000-3500 BC.

Natural neighbor interpolation of WHG ancestry among Eneolithic populations. See full map.

Anatolia Neolithic ancestry clearly spread to the east into the north Pontic area through a Middle Eneolithic mating network, most likely opened after the Khvalynsk expansion:

Regarding Y-chromosome haplogroups, Anthony (2019) insists on the evident association of Khvalynsk, Yamnaya, and the spread of Pre-Yamnaya and Yamnaya ancestry with the expansion of elite R1b-L754 (and some I2a2) individuals:

3. Early Bronze Age

Data from Wang et al. (2019) show that Corded Ware-derived populations do not have good fits for Eneolithic_Steppe-like ancestry, no matter the model. In other words: Corded Ware populations show not only a higher contribution of Anatolia Neolithic ancestry (ca. 20-30% compared to the ca. 2-10% of Yamnaya); they show a different EHG + CHG combination compared to the Pre-Yamnaya one.

Yamnaya Kalmykia and Afanasievo show the closest fits to the Eneolithic population of the North Caucasian steppes, rejecting thus sizeable contributions from Anatolia Neolithic and/or WHG, as shown by the SD values. Both probably show then a Pre-Yamnaya ancestry closest to the late Repin population.

EBA maps include data from Wang et al. (2018) supplementary materials, specifically unpublished Yamnaya samples from Hungary that appeared in analysis of the preprint, but which were taken out of the definitive paper. Their location among Yamnaya settlers from Hungary is speculative, although most uncovered kurgans in Hungary are concentrated in the Tisza-Danube interfluve.

The Y-chromosome bottleneck of elite males from Proto-Indo-European clans under R1b-L754 and some I2a2 subclades, already visible in the Khvalynsk sampling, became even more noticeable in the subsequent expansion of late Repin/early Yamnaya elites under R1b-L23 and I2a-L699:

Maps of CHG, EHG, Anatolia Neolithic, and probably WHG show the expansion of these components among Corded Ware-related groups in North Eurasia, apart from other cultures close to the Caucasus:

4. Middle to Late Bronze Age

The following maps show the most likely distribution of Yamnaya ancestry during the Bell Beaker-, Balkan-, and Sintashta-Potapovka-related expansions.

4.1. Bell Beakers

The amount of Yamnaya ancestry is probably overestimated among populations where Bell Beakers replaced Corded Ware. A map of Yamnaya ancestry among Bell Beakers gets trickier for the following reasons:

  • Expanding Repin peoples of Pre-Yamnaya ancestry must have had admixture through exogamy with late Sredni Stog/Proto-Corded Ware peoples during their expansion into the North Pontic area, and Sredni Stog in turn had probably some Pre-Yamnaya admixture, too (although they don’t appear in the simplistic formal stats above). This is supported by the increase of Anatolia farmer ancestry in more western Yamna samples.
  • Later, Yamnaya admixed through exogamy with Corded Ware-like populations in Central Europe during their expansion. Even samples from the Middle to Upper Danube and around the Lower Rhine will probably show increasing contributions of Steppe_MLBA, at the same time as they show an increasing proportion of EEF-related ancestry.
  • To complicate things further, the late Corded Ware Espersted family (from ca. 2500 BC or later) shows, in turn, what seems like a recent admixture with Yamnaya vanguard groups, with the sample of highest Yamnaya ancestry being the paternal uncle of other individuals (all of hg. R1a-M417), suggesting that there might have been many similar Central European mating networks from the mid-3rd millennium BC on, of (mainly) Yamnaya-like R1b elites displaying a small proportion of CW-like ancestry admixing through exogamy with Corded Ware-like peoples who already had some Yamnaya ancestry.
Natural neighbor interpolation of Yamnaya ancestry among Middle to Late Bronze Age populations (Esperstedt CWC site close to BK_DE, label is hidden by BK_DE_SAN). See full map. You can see how this map correlated with the map of Late Copper Age migrations and Yamanaya into Bell Beaker expansion.

NOTE. Terms like “exogamy”, “male-driven migration”, and “sex bias”, are not only based on the Y-chromosome bottlenecks visible in the different cultural expansions since the Palaeolithic. Despite the scarce sampling available in 2017 for analysis of “Steppe ancestry”-related populations, it appeared to show already a male sex bias in Goldberg et al. (2017), and it has been confirmed for Neolithic and Copper Age population movements in Mathieson et al. (2018) – see Supplementary Table 5. The analysis of male-biased expansion of “Steppe ancestry” in CWC Esperstedt and Bell Beaker Germany is, for the reasons stated above, not very useful to distinguish their mutual influence, though.

Based on data from Olalde et al. (2019), Bell Beakers from Germany are the closest sampled ones to expanding East Bell Beakers, and those close to the Rhine – i.e. French, Dutch, and British Beakers in particular – show a clear excess “Steppe ancestry” due to their exogamy with local Corded Ware groups:

Only one 2-way model fits the ancestry in Iberia_CA_Stp with P-value>0.05: Germany_Beaker + Iberia_CA. Finding a Bell Beaker-related group as a plausible source for the introduction of steppe ancestry into Iberia is consistent with the fact that some of the individuals in the Iberia_CA_Stp group were excavated in Bell Beaker associated contexts. Models with Iberia_CA and other Bell Beaker groups such as France_Beaker (P-value=7.31E-06), Netherlands_Beaker (P-value=1.03E-03) and England_Beaker (P-value=4.86E-02) failed, probably because they have slightly higher proportions of steppe ancestry than the true source population.


The exogamy with Corded Ware-like groups in the Lower Rhine Basin seems at this point undeniable, as is the origin of Bell Beakers around the Middle-Upper Danube Basin from Yamnaya Hungary.

To avoid this excess “Steppe ancestry” showing up in the maps, since Bell Beakers from Germany pack the most Yamnaya ancestry among East Bell Beakers outside Hungary (ca. 51.1% “Steppe ancestry”), I equated this maximum with BK_Scotland_Ach (which shows ca. 61.1% “Steppe ancestry”, highest among western Beakers), and applied a simple rule of three for “Steppe ancestry” in Dutch and British Beakers.

NOTE. Formal stats for “Steppe ancestry” in Bell Beaker groups are available in Olalde et al. (2018) supplementary materials (PDF). I didn’t apply this adjustment to Bk_FR groups because of the R1b Bell Beaker sample from the Champagne/Alsace region reported by Samantha Brunel that will pack more Yamnaya ancestry than any other sampled Beaker to date, hence probably driving the Yamnaya ancestry up in French samples.

The most likely outcome in the following years, when Yamnaya and Corded Ware ancestry are investigated separately, is that Yamnaya ancestry will be much lower the farther away from the Middle and Lower Danube region, similar to the case in Iberia, so the map above probably overestimates this component in most Beakers to the north of the Danube. Even the late Hungarian Beaker samples, who pack the highest Yamnaya ancestry (up to 75%) among Beakers, represent likely a back-migration of Moravian Beakers, and will probably show a contribution of Corded Ware ancestry due to the exogamy with local Moravian groups.

Despite this decreasing admixture as Bell Beakers spread westward, the explosive expansion of Yamnaya R1b male lineages (in words of David Reich) and the radical replacement of local ones – whether derived from Corded Ware or Neolithic groups – shows the true extent of the North-West Indo-European expansion in Europe:

Y-DNA haplogroups in West Eurasia during the Bell Beaker expansion. See full map and see maps of cultures, ADMIXTURE, Y-DNA, and mtDNA of the Late Copper Age and of the Yamnaya-Bell Beaker transition.

4.2. Palaeo-Balkan

There is scarce data on Palaeo-Balkan movements yet, although it is known that:

  1. Yamnaya ancestry appears among Mycenaeans, with the Yamnaya Bulgaria sample being its best current ancestral fit;
  2. the emergence of steppe ancestry and R1b-M269 in the eastern Mediterranean was associated with Ancient Greeks;
  3. Thracians, Albanians, and Armenians also show R1b-M269 subclades and “Steppe ancestry”.

4.3. Sintashta-Potapovka-Filatovka

Interestingly, Potapovka is the only Corded Ware derived culture that shows good fits for Yamnaya ancestry, despite having replaced Poltavka in the region under the same Corded Ware-like (Abashevo) influence as Sintashta.

This proves that there was a period of admixture in the Pre-Proto-Indo-Iranian community between CWC-like Abashevo and Yamnaya-like Catacomb-Poltavka herders in the Sintashta-Potapovka-Filatovka community, probably more easily detectable in this group because of the specific temporal and geographic sampling available.

Supplementary Table 14. P values of rank=3 and admixture proportions in modelling Steppe ancestry populations as a four-way admixture of distal sources EHG, CHG, Anatolian_Neolithic and WHG using 14 outgroups.
Left populations: Steppe cluster, EHG, CHG, WHG, Anatolian_Neolithic
Right populations: Mbuti.DG, Ust_Ishim.DG, Kostenki14, MA1, Han.DG, Papuan.DG, Onge.DG, Villabruna, Vestonice16, ElMiron, Ethiopia_4500BP.SG, Karitiana.DG, Natufian, Iran_Ganj_Dareh_Neolithic.

Srubnaya ancestry shows a best fit with non-Pre-Yamnaya ancestry, i.e. with different CHG + EHG components – possibly because the more western Potapovka (ancestral to Proto-Srubnaya Pokrovka) also showed good fits for it. Srubnaya shows poor fits for Pre-Yamnaya ancestry probably because Corded Ware-like (Abashevo) genetic influence increased during its formation.

On the other hand, more eastern Corded Ware-derived groups like Sintashta and its more direct offshoot Andronovo show poor fits with this model, too, but their fits are still better than those including Pre-Yamnaya ancestry.

The bottleneck of Proto-Indo-Iranians under R1a-Z93 was not yet complete by the time when the Sintashta-Potapovka-Filatovka community expanded with the Srubna-Andronovo horizon:

4.4. Afanasevo

At the end of the Afanasevo culture, at least three samples show hg. Q1a2-M25 (ca. 2900-2500 BC), which seemed to point to a resurgence of local lineages, despite continuity of the prototypical Pre-Yamnaya ancestry. On the other hand, Anthony (2019) makes this cryptic statement:

Yamnaya men were almost exclusively R1b, and pre-Yamnaya Eneolithic Volga-Caspian-Caucasus steppe men were principally R1b, with a significant Q1a minority.

Since the only available samples from the Khvalynsk community are R1b (x3), Q1a(x1), and R1a(x1), it seems strange that Anthony would talk about a “significant minority”, unless Q1a will pop up in some more individuals of those ca. 30 new to be published. Because he also mentions I2a2 as appearing in one elite burial, it seems Q1a (like R1a-M459) will not appear under elite kurgans, although it is still possible that hg. Q1a was involved in the expansion of Afanasevo to the east.

Y-DNA haplogroups in West Eurasia during the Middle Bronze Age. See full map and see maps of cultures, ADMIXTURE, Y-DNA, and mtDNA of the Middle Bronze Age and the Late Bronze Age.

Okunevo, which replaced Afanasevo in the Altai region, shows a majority of hg. Q1a2-M25, and at least one Q1a1-B284, but also some R1b-M269 samples proper of Afanasevo, suggesting partial genetic continuity.

NOTE. Other sampled Siberian populations clearly show a variety of Q subclades that likely expanded during the Palaeolithic, such as Baikal EBA samples from Ust’Ida and Shamanka with a majority of Q1a2-M25 (in particular Q1a2-L712), and hg. Q reported from Elunino, Sagsai, Khövsgöl, and also among peoples of the Srubna-Andronovo horizon (the Krasnoyarsk MLBA outlier), and in Karasuk. Q1a-M25 was earlier found in a Baltic hunter-gatherer, which supports a widespread distribution of Q1a2 and Q1a1 in North Eurasia during the Neolithic and Bronze Age.

From Damgaard et al. Science (2018):

(…) in contrast to the lack of identifiable admixture from Yamnaya and Afanasievo in the CentralSteppe_EMBA, there is an admixture signal of 10 to 20% Yamnaya and Afanasievo in the Okunevo_EMBA samples, consistent with evidence of western steppe influence. This signal is not seen on the X chromosome (qpAdm P value for admixture on X 0.33 compared to 0.02 for autosomes), suggesting a male-derived admixture, also consistent with the fact that 1 of 10 Okunevo_EMBA males carries a R1b1a2a2 Y chromosome related to those found in western pastoralists. In contrast, there is no evidence of western steppe admixture among the more eastern Baikal region region Bronze Age (~2200 to 1800 BCE) samples.

This Yamnaya ancestry has been also recently found to be the best fit for the Iron Age population of Shirenzigou in Xinjiang – where Tocharian languages were attested centuries later – despite the haplogroup diversity acquired during their evolution, likely through an intermediate Chemurchek culture (see a recent discussion on the elusive Proto-Tocharians).

Haplogroup diversity seems to be common in Iron Age populations all over Eurasia, most likely due to the spread of different types of sociopolitical structures where alliances played a more relevant role in the expansion of peoples. A well-known example of this is the spread of Akozino warrior-traders in the whole Baltic region under a partial N1a-VL29-bottleneck associated with the emerging chiefdom-based systems under the influence of expanding steppe nomads.

Y-DNA haplogroups in West Eurasia during the Early Iron Age. See full map and see maps of cultures, ADMIXTURE, Y-DNA, and mtDNA of the Early Iron Age and Late Iron Age.

Surprisingly, then, Proto-Tocharians from Shirenzigou pack up to 74% Yamnaya ancestry, in spite of the 2,000 years that separate them from the demise of the Afanasevo culture. They show more Yamnaya ancestry than any other population by that time, being thus a sort of Late PIE fossils not only in their archaic dialect, but also in their genetic profile:


The recent intrusion of Corded Ware-like ancestry, as well as the variable admixture with Siberian and East Asian populations, both point to the known intense Old Iranian and Old/Middle Chinese contacts. The scarce Proto-Samoyedic and Proto-Turkic loans in Tocharian suggest a rather loose, probably more distant connection with East Uralic and Altaic peoples from the forest-steppe and steppe areas to the north (read more about external influences on Tocharian).

Interestingly, both R1b samples, MO12 and M15-2 – likely of Asian R1b-PH155 branch – show a best fit for Andronovo/Srubna + Hezhen/Ulchi ancestry, suggesting a likely connection with Iranians to the east of Xinjiang, who later expanded as the Wusun and Kangju. How they might have been related to Huns and Xiongnu individuals, who also show this haplogroup, is yet unknown, although Huns also show hg. R1a-Z93 (probably most R1a-Z2124) and Steppe_MLBA ancestry, earlier associated with expanding Iranian peoples of the Srubna-Andronovo horizon.

All in all, it seems that prehistoric movements explained through the lens of genetic research fit perfectly well the linguistic reconstruction of Proto-Indo-European and Proto-Uralic.


Volga Basin R1b-rich Proto-Indo-Europeans of (Pre-)Yamnaya ancestry


New paper (behind paywall) by David Anthony, Archaeology, Genetics, and Language in the Steppes: A Comment on Bomhard, complementing in a favourable way Bomhard’s Caucasian substrate hypothesis in the current issue of the JIES.

NOTE. I have tried to access this issue for some days, but it’s just not indexed in my university library online service (ProQuest) yet. This particular paper is on Academia.edu, though, as are Bomhard’s papers on this issue in his site.

Interesting excerpts (emphasis mine):

Along the banks of the lower Volga many excavated hunting-fishing camp sites are dated 6200-4500 BC. They could be the source of CHG ancestry in the steppes. At about 6200 BC, when these camps were first established at Kair Shak III and Varfolomievka (42 and 28 on Figure 2), they hunted primarily saiga antelope around Dzhangar, south of the lower Volga, and almost exclusively onagers in the drier desert-steppes at Kair-Shak, north of the lower Volga. Farther north at the lower/middle Volga ecotone, at sites such as Varfolomievka and Oroshaemoe hunter-fishers who made pottery similar to that at Kair-Shak hunted onagers and saiga antelope in the desert-steppe, horses in the steppe, and aurochs in the riverine forests. Finally, in the Volga steppes north of Saratov and near Samara, hunter-fishers who made a different kind of pottery (Samara type) and hunted wild horses and red deer definitely were EHG. A Samara hunter-gatherer of this era buried at Lebyazhinka IV, dated 5600-5500 BC, was one of the first named examples of the EHG genetic type (Haak et al. 2015). This individual, like others from the same region, had no or very little CHG ancestry. The CHG mating network had not yet reached Samara by 5500 BC.

Eneolithic settlements (1–5, 7, 10–16, 20, 22–43, 48, 50), burial grounds (6, 8–9, 17–19, 21, 47, 49) and kurgans (44–46) of the steppe Ural-Volga region: 1 Ivanovka; 2 Turganik; 3 Kuzminki; 4 Mullino; 5 Davlekanovo; 6 Sjezheye (burial ground); 7 Vilovatoe; 8 Ivanovka; 9 Krivoluchye; 10–13 LebjazhinkaI-III-IV-V; 14 Gundorovka; 15–16 Bol.

Pushkino; 48 Elshanka; 49 Novoorsk; 50 Khutor Repin. Modified from Morgunova (2014).

But before 4500 BC, CHG ancestry appeared among the EHG hunter-fishers in the middle Volga steppes from Samara to Saratov, at the same time that domesticated cattle and sheep-goats appeared. The Reich lab now has whole-genome aDNA data from more than 30 individuals from three Eneolithic cemeteries in the Volga steppes between the cities of Saratov and Samara (Khlopkov Bugor, Khvalynsk, and Ekaterinovka), all dated around the middle of the fifth millennium BC. Many dates from human bone are older, even before 5000 BC, but they are affected by strong reservoir effects, derived from a diet rich in fish, making them appear too old (Shishlina et al 2009), so the dates I use here accord with published and unpublished dates from a few dated animal bones (not fish-eaters) in graves.

Only three individuals from Khvalynsk are published, and they were first published in a report that did not mention the site in the text (Mathieson et al. 2015), so they went largely unnoticed. Nevertheless, they are crucial for understanding the evolution of the Yamnaya mating network in the steppes. They were mentioned briefly in Damgaard et al (2018) but were not graphed. They were re-analyzed and their admixture components were illustrated in a bar graph in Wang et al (2018: figure 2c), but they are not the principal focus of any published study. All of the authors who examined them agreed that these three Khvalynsk individuals, dated about 4500 BC, showed EHG ancestry admixed substantially with CHG, and not a trace of Anatolian Farmer ancestry, so the CHG was a Hotu-Cave or Kotias-Cave type of un-admixed CHG. The proportion of CHG in the Wang et al. (2018) bar graphs is about 20-30% in two individuals, substantially less CHG than in Yamnaya; but the third Khvalynsk individual had more than 50% CHG, like Yamnaya. The ca. 30 additional unpublished individuals from three middle Volga Eneolithic cemeteries, including Khvalynsk, preliminarily show the same admixed EHG/CHG ancestry in varying proportions. Most of the males belonged to Y-chromosome haplogroup R1b1a, like almost all Yamnaya males, but Khvalynsk also had some minority Y-chromosome haplogroups (R1a, Q1a, J, I2a2) that do not appear or appear only rarely (I2a2) in Yamnaya graves.

Wang et al. (2018) discovered that this middle Volga mating network extended down to the North Caucasian steppes, where at cemeteries such as Progress-2 and Vonyuchka, dated 4300 BC, the same Khvalynsk-type ancestry appeared, an admixture of CHG and EHG with no Anatolian Farmer ancestry, with steppe-derived Y-chromosome haplogroup R1b. These three individuals in the North Caucasus steppes had higher proportions of CHG, overlapping Yamnaya. Without any doubt, a CHG population that was not admixed with Anatolian Farmers mated with EHG populations in the Volga steppes and in the North Caucasus steppes before 4500 BC. We can refer to this admixture as pre-Yamnaya, because it makes the best currently known genetic ancestor for EHG/CHG R1b Yamnaya genomes. The Progress-2 individuals from North Caucasus steppe graves lived not far from the pre-Maikop farmers of the Belaya valley, but they did not exchange mates, according to their DNA.

The hunter-fisher camps that first appeared on the lower Volga around 6200 BC could represent the migration northward of un-admixed CHG hunter-fishers from the steppe parts of the southeastern Caucasus, a speculation that awaits confirmation from aDNA. After 5000 BC domesticated animals appeared in these same sites in the lower Volga, and in new ones, and in grave sacrifices at Khvalynsk and Ekaterinovka. CHG genes and domesticated animals flowed north up the Volga, and EHG genes flowed south into the North Caucasus steppes, and the two components became admixed. After approximately 4500 BC the Khvalynsk archaeological culture united the lower and middle Volga archaeological sites into one variable archaeological culture that kept domesticated sheep, goats, and cattle (and possibly horses). In my estimation, Khvalynsk might represent the oldest phase of PIE.

Anatolian Farmer ancestry and Yamnaya origins

The Eneolithic Volga-North Caucasus mating network (Khvalynsk/Progress-2 type) exhibited EHG/CHG admixtures and Y-chromosome haplogroups similar to Yamnaya, but without Yamnaya’s additional Anatolian Farmer ancestry. (…)

Like the Mesolithic and Neolithic populations here, the Eneolithic populations of Dnieper-Donets II type seem to have limited their mating network to the rich, strategic region they occupied, centered on the Rapids. The absence of CHG shows that they did not mate frequently if at all with the people of the Volga steppes, a surprising but undeniable discovery. Archaeologists have seen connections in ornament types and in some details of funeral ritual between Dnieper-Donets cemeteries of the Mariupol-Nikol’skoe type and cemeteries in the middle Volga steppes such as Khvalynsk and S’yez’zhe (Vasiliev 1981:122-123). Also their cranio-facial types were judged to be similar (Bogdanov and Khokhlov 2012:212). So it it surprising that their aDNA does not indicate any genetic admixture with Khvalynsk or Progress-2. Also, neither they nor the Volga steppe Eneolithic populations showed any Anatolian Farmer ancestry. (…)

All three of the steppe-admixed exceptions were from the Varna region (Mathieson et al. 2018). One of them was the famous “golden man’ at Varna (Krause et al. 2016), Grave 43, whose steppe ancestry was the most doubtful of the three. If he had steppe ancestry, it was sufficiently distant (five+ generations before him) that he was not a statistically significant outlier, but he was displaced in the steppe direction, away from the central values of the majority of typical Anatolian Farmers at Varna and elsewhere. The other two, at Varna (grave 158, a 5-7-year-old girl) and Smyadovo (grave 29, a male 20-25 years old), were statistically significant outliers who had recent steppe ancestry (consistent with grandparents or great-grandparents) of the EHG/CHG Khvalynsk/Progress-2 type, not of the Dnieper Rapids EHG/WHG type.

(…) I believe that the Suvorovo-Cernavoda I movement into the lower Danube valley and the Balkans about 4300 BC separated early PIE-speakers (pre-Anatolian) from the steppe population that stayed behind in the steppes and that later developed into late PIE and Yamnaya.

This archaeological transition marked the breakdown of the mating barrier between steppe and Anatolian Farmer mating networks. After this 4300-4200 BC event, Anatolian Farmer ancestry began to pop up in the steppes. The currently oldest sample with Anatolian Farmer ancestry in the steppes in an individual at Aleksandriya, a Sredni Stog cemetery on the Donets in eastern Ukraine. Sredni Stog has often been discussed as a possible Yamnaya ancestor in Ukraine (Anthony 2007: 239- 254). The single published grave is dated about 4000 BC (4045– 3974 calBC/ 5215±20 BP/ PSUAMS-2832) and shows 20% Anatolian Farmer ancestry and 80% Khvalynsk-type steppe ancestry (CHG&EHG). His Y-chromosome haplogroup was R1a-Z93, similar to the later Sintashta culture and to South Asian Indo-Aryans, and he is the earliest known sample to show the genetic adaptation to lactase persistence (I3910-T). Another pre-Yamnaya grave with Anatolian Farmer ancestry was analyzed from the Dnieper valley at Dereivka, dated 3600-3400 BC (grave 73, 3634–3377 calBC/ 4725±25 BP/ UCIAMS-186349). She also had 20% Anatolian Farmer ancestry, but she showed less CHG than Aleksandriya and more Dereivka-1 ancestry, not surprising for a Dnieper valley sample, but also showing that the old fifth-millennium-type EHG/WHG Dnieper ancestry survived into the fourth millennium BC in the Dnieper valley (Mathieson et al. 2018).

Pontic-Caspian steppe and neighbouring groups in the Late Eneolithic. See full map.

Probably, late PIE (Yamnaya) evolved in the same part of the steppes—the Volga-Caucasus steppes between the lower Don, the lower and middle Volga, and the North Caucasus piedmont—where early PIE evolved, and where appropriate EHG/CHG admixtures and Y-chromosome haplogroups were seen already in the Eneolithic (without Anatolian Farmer). There have always been archaeologists who argued for an origin of Yamnaya in the Volga steppes, including Gimbutas (1963), Merpert (1974), and recently Morgunova (2014), who argued that this was where Repin-type ceramics, an important early Yamnaya pottery type, first appeared in dated contexts before Yamnaya, about 3600 BC. The genetic evidence is consistent with Yamnaya EHG/CHG origins in the Volga-Caucasus steppes. Also, if contact with the Maikop culture was a fundamental cause of the innovations in transport and metallurgy that defined the Yamnaya culture, then the lower Don-North Caucasus-lower Volga steppes, closest to the North Caucasus, would be where the earliest phase is expected.

I would still guess that the Darkveti-Meshoko culture and its descendant Maikop culture established the linguistic ancestor of the Northwest Caucasian languages in approximately the region where they remained. I also accept the general consensus that the appearance of the hierarchical Maikop culture about 3600 BC had profound effects on pre-Yamnaya and early Yamnaya steppe cultures. Yamnaya metallurgy borrowed from the Maikop culture two-sided molds, tanged daggers, cast shaft hole axes with a single blade, and arsenical copper. Wheeled vehicles might have entered the steppes through Maikop, revolutionizing steppe economies and making Yamnaya pastoral nomadism possible after 3300 BC.

For those who still hoped that Proto-Indo-Europeans of Yamnaya/Afanasievo ancestry from the Don-Volga region were associated with the expansion of hg. R1a-M417, in a sort of mythical “R1-rich” Indo-European society, it seems this is going to be yet another prediction based on ancestry magic that goes wrong.

Proto-Indo-Europeans were, however, associated with other subclades beyond R1b-M269, probably (as I wrote recently) R1b-V1636, I2a-L699, Q1a-M25, and R1a-YP1272, but also interestingly some J subclade, so let’s see what surprises the new study on Khvalynsk and Yamnaya settlers from the Carpathian Basin brings…

On the bright side, it is indirectly confirmed that late Sredni Stog formed part of the neighbouring Corded Ware-like populations of ca. 20-30%+ Anatolian farmer ancestry that gave Yamnaya its share (ca. 6-10%), relative to the comparatively unmixed Khvalynsk and late Repin population (as shown by Afanasevo).

In this steppe mating network that opened up after the Khvalynsk expansion, the increasing admixture of Anatolian farmer-related ancestry in Yamnaya from east (ca. 2-10%) to west (ca. 6-15%) points to an exogamy of late Repin males in their western/south-western regions with populations around the Don River basin and beyond (and endogamy within the Yamnaya community), in an evolution relevant for language expansions and language contacts during the Late Eneolithic.

NOTE. “Mating network” is my new preferred term for “ancestry”. Also great to see scholars finally talk about “Pre-Yamnaya” ancestry, which – combined with the distinction of Yamnaya from Corded Ware ancestry – will no doubt help differentiate fine-scale population movements of steppe- and forest-steppe-related populations.

The whole issue of the JIES is centered on Caucasian influences on Early PIE as an Indo-Uralic dialect, and this language contact/substrate is useful to locate the most likely candidates for the Northeast and Northwest Caucasian and the Proto-Indo-European homelands.

On the other hand, it would also be interesting to read a discussion of how this Volga homeland of Middle PIE and Don-Volga-Ural homeland of Late PIE would be reconciled with the known continuous contacts of Uralic with Middle and Late PIE (see here) to locate the most likely Proto-Uralic homeland.

Especially because Corded Ware fully replaced all sub-Neolithic groups to the north and east of Khvalynsk/Yamnaya, like Volosovo, so no other population neighbouring Middle and Late Proto-Indo-Europeans survived into the Bronze Age…

EDIT: For those new to this blog, this information on unpublished samples from the Volga River basin is yet another confirmation of Khokhlov’s report on the R1b-L23 samples from Yekaterinovka, and its confirmation by a co-author of The unique elite Khvalynsk male from a Yekaterinovskiy Cape burial, apart from more support to the newest data placing Yekaterinovka culturally and probably chronologically between Samara and Khvalynsk.


Kurgan origins and expansion with Khvalynsk-Novodanilovka chieftains


The concept of ‘Kurgan peoples’ is a general idea whereby ‘kurgan builders’ are identified with Indo-European speakers. It is a consequence of the oversimplification of Gimbutas’ theory, and is still widespread among linguists, archaeologists, geneticists, and amateurs alike.

NOTE. On the already simplistic assumptions of Gimbutas regarding the so-called ‘kurgan’ burials, see e.g. Häusler’s early criticism.

However, as more ancient DNA studies appear, many ancient cultures once held as ‘kurganized’ are becoming more and more clearly disconnected from Proto-Indo-Europeans: So for example Varna, Cucuteni-Trypillia, Maykop, or Northern Iranian kurgan builders.

The first marked burials

In his chapter Aspects of Pontic Steppe Development (4550-3000 BC), Ukrainian researcher Yuri Rassamakin makes some interesting remarks.

NOTE. As you may know, Rassamakin supports a ‘Skelyan’ (macro-)culture encompassing every group from the North Pontic steppe and steppe-forest, where (therefore) Novodanilovka or Suvorovo would be just rich elites among Sredni Stog and related ‘commoners’. So he can hardly be described as interested in supporting Khvalynsk over Sredni Stog influence…

The first period of development (ca. 4550 – 4100/4000 BC) is marked as a period of emergence of the first burial symbols.

Gimbutas – like later her pupil Mallory -, Merpert, or Danilenko believed that the first mark of emerging kurgans were precisely the presence of constructions above burials, such as simple, small, stone henges, dolmens, cists, or cairns. Hence the traditional connection of ‘kurgans’ with Sredni Stog. This Sredni Stog connection is currently still a widespread belief, that is kept alive because it appears in many secondary sources (e.g. the much beloved as it is outdated and simplistic reference book Encyclopedia of Indo-European Culture).

These first constructions described as from Sredni Stog were nevertheless found solely among Sredni Stog ‘elites’. That is, burials from Novodanlilovka-type cultural sites. So, following the initial assessments of this culture by Soviet archaeologists (like Telegin), for Gimbutas (1956) they were among ‘Sredni Stog’ burials, and for Merpert (1959) they might have been due to an “initial, genetic basis” originally from Khvalynsk, and thus (what was described as) Sredni Stog seemed to have been formed under “strong eastern influences”.

NOTE. From Rassamakin’s own account: Gimbutas’ model was later corrected, when in the mid-1980s Telegin judged that the cemeteries in fact represented an independent cultural type (Novodanilovka-type sites), developing over two stages (Telegin 1985a, 311-20; 1991). These were the same burials which Danilenko thought reflected a distinct pastoralist culture among the early Yamnaya tribes, which Gimbutas attributed to the first kurgan wave, and which Merpert, in part, ascribed to the first chronological period of the early Yamnaya culture-historical province.

The classification of megalithic monuments of the Pantie steppe. (After Dovzhenko 1993, fig. 1 with changes by the author.)

These early constructions, however, are not found anywhere else in the North Pontic region except for those ‘Sredni Stog elites’:

  • Rooves made from separate slabs with cairns are known in the Dnieper and Volga regions: In the Khvalynsk I culture, 17% of burials were superimposed with stone cairns or had a single stone marker.
  • Cists with cairns are known from Severskii Donets and Azov areas.
  • A unique cromlech is described from the Dniester-Danube area (Suvorovo).
  • In the remaining cases, especially for the Volga area and pre-Caucasus steppe, there are some specific variants:
    1. Use of natural hills as a burial marker
    2. Presence of smalll earthen or wooden constructions.

If we accept that these constructions are the first rudimentary kurgans or proto-kurgans, and that kurgans were a mark of expanding Indo-European culture, let’s see who built them first and why:

The emergence of kurgans

emergence-kurganIn his book Рождение Кургана (2012), The Emergence of the Kurgan, Sergei Korenevskiy makes a thorough analysis of the first kurgan finds.

The Novodanilovka group (ca. 4500-4000 BC), coincident with the Trypillia B1 stage, is characterized by the presence of ochre (in great quantity) in burials, as seen in Khvalynsk, as well as stone constructions in burials.

NOTE. Similarly to Rassamakin, Korenevskiy believes in the unity of North Pontic cultures, and specifically of Novodanilovka chiefs among Sredni Stog commoners, and of all of them with Khvalynsk in a Khvalynsk-Sredni Stog cultural-historical region, because of their “chronological and regional coincidence” and similar pottery, in spite of differences in burial and symbolism. So, hardly an interested party in supporting the expansion of Khvalynsk to the west, either.

Obviously, for those of us who believe that symbolism and burials do mean something beyond similar pottery decoration, in the instances where Sredni Stog appears in his text, it should be read Novodanilovka (and Khvalynsk-Sredni Stog should be read Khvalynsk-Novodanilovka) instead; because he is not referring to the older Khvalynsk – Sredni Stog community of the beginning of the 5th millennium, but to a very distinct group of sites related to the Khvalynsk expansion with horse symbolism at the end of the 5th millenium.

For the early Eneolithic time and the existence of the Khvalynsk-Sredni Stog community, on the problem under consideration, the main source [of knowledge for the first kurgans] may be the Nalchik and Khvalynsk burial grounds.

The kurgans themselves were not simple pits filled with earth. There was a belief that the funerary structure was the place where the buried moved to another world. Most likely, such a place could be considered to be a generic collective cemetery.

The second important point may be that the Eneolithic era was the time of development of a prestigious economy that created its values ​​in the form of different things. Among them were items requiring high skills or manufacturing techniques (different woolen tools, scepters, stone bracelets), as well as tools that occupy an important role in labor, war and industry (stone flat axes, arrowheads, knife-like plates and chips of flint). The decorations of the burial costume included certain iconic objects – bone plates from canine fang, pins, bone sticks with a hole- “zurki”).

Presented were a variety of beads from bone, stone, shell. Bead washers could be collected in whole garlands, thus acquiring a special value. Prestigious cult things, presumably, were copper jewelry: beads, rings, bracelets. They, like the shells, were products of the gift exchange and reflected the direct or indirect involvement of the owners.

Khvalynsk and Nalchik first marked burials

[The Nalchik burials:] with respect to the reconstruction of social relations, data are few. In general, the funerary practice of this necropolis does not reflect the position of any fighting tools in the grave. (…)

Judging by the rare ornaments from the burials of the necropolis, the population that left it was implicated in the prestigious values of the Khvalynsk-Sredni Stog community. A more detailed picture of the era of early Eneolithic reflects the data of the Khvalynsk-type burial ground.

The dashed line illustrates a hypothetical geographic border between genetically distinct Steppe and Caucasus clusters.

(…) the Khvalynsk burial ground was characterized by a system of age groups and a forming social structure based on the hierarchy of estate groups. The social organization of Khvalynians can be characterized by the stage of evolution of a small-family variant of the development of a primitive society, in which the social status of a man and a woman became closer. The role of the married woman / mother was accentuated. Archaeological signs of this process can be considered joint burials of old people and children and as part of burials with same and mixed genders.

Statistics of the Khvalynsk burial ground. Примечание: ж. — женский, п. — подросток, р. — ребенок, м. — мужской, вз. — взрослый

In summary, one can arrive at the following conclusions. It is unlikely to be a mistake if we assume that the Khvalynsk burial ground was abandoned by a local community that lived on the basis of the tribal collective. Their economic activities were connected with hunting, fishing, homestead cattle breeding with an obvious acquaintance with the horse (it is not known if the object of hunting or domestication). In the mythology of the afterlife and the funerary traditions of the Khvalynians, the same egalitarianism of the forms of funerary buildings was dominant, but signs of the personification of graves began to appear, with marks in the rarest of cases with stones.

Unlike the Nalchik cemetery, in the Khvalynsk and Khlopkovsky burial grounds, new trends in assessments of the suitability of implements for funerary practice are clearly discernible. So, they expressed themselves in the appearance of rare graves with scepters, axes – buggers, stone adzes, harpoons and fishing hooks. Basically, all these symbols of the rite are associated with male burials. The least saturated with burial items with stone adzes, and they are represented in small forms. But the fact is important. Society began to pay attention to these categories of objects, linking their symbols with mythological ideas about the things of the afterlife and their functions in the “other dimension of reality” specifically as tools of war and symbols of military power or valor (axes with trunnions), spiritual power (scepters), as well as woodworking (adzes). In terms of “wealth”, these complexes were not particularly distinguished from other inventory sets.

The population that left the Khvalynsk burial ground had to do with the deficit of the era, which was copper products. The latter emphasized, apparently, the age status of some men from 40 to 60 years old and adult women. Another scarce raw material could be a sea shell (item 38) from the burial of a man aged 25-35 years.

As a result, it can be concluded that the complexes of funerary ritual of the Khvalynsk burial ground indicate the existence of ideas about a person at the time of his transition to another world, as a member of the collective of the clan (community) with the admitted individual prestige of things that emphasize his age or social status, but in the framework of the common egalitarian tradition of a collective necropolis. At this time, presumably, views were developing on the relationship of the things put in the grave with the “property” of the buried.

The aftermath of the kurgan expansion

The most important phenomenon in the Weltanschauung of the late Eneolithic population in the steppes of Eastern Europe and Ciscaucasia was the spread of the religious tradition, relatively new in comparison with the time of the Mariupol cultural and historical community, according to which the deceased began to go to another world in a position on his back, crocheted, in the company of ochre magic.

This position appears to be dominant in the materials of the Khvalynsk cemetery, and as a very significant – but not dominant – feature of the materials of the Nalchik cemetery. The posture on the back is crocheted, becoming typical for the Sredni Stog culture, as well as the bearers of the oldest Kurgan traditions in the Ciscaucasia and the Volga-Don region.

Our position on this issue is as follows. I can fully adhere to the opinion of B. Govedaritsa and I.V. Manzura that the transition of the population of the Khvalynsk – Sredni Stog community to the tradition of the burial crouched on their backs looks like the most important ideological innovation in the mythology of death among the local population of Eastern Europe and Ciscaucasia in relation to the earlier time of the Mariupol cultural and historical community.

Chronology of Cucuteni-Tripolye cultures after Videiko (2004), with corresponding Khvalynsk / Nalchik / Novodanilovka / Pre-Maykop / Maykop kurgans.

In the funerary practice of this cultural education there is much in common with the traditions of the funerary practice of the Balkan-Danube region. At the same time, the posture pose on the back is spread more widely in the Neolithic and Eneolithic than only Western Europe. It was recorded in the necropolis of Kul-Tepe I in Azerbaijan (Abibulaev, 1982), the necropolis of Tepe Gissar in Iran (Schmidt, 1933, 1937), in burials 1, 2 in the settlement of Poylu II of Leleatepin culture in Azerbaijan (the Kura valley) (Museibli , 2010. P. 208). In other words, it is the same universal way of inhumation, like a pose on one side or a burial on the back, although not so widespread on a global scale.

From where and how such ritualism could appear in its specific carriers, it definitely cannot always be established. But let us pay attention to the fact that the peculiarity of the posture of the deceased population of the Khvalynsk – Sredni Stog community on the back is that the deceased was not simply placed on his back, he was often heavily sprinkled with ochre. The last detail of the ritual clearly has a prototype for the carriers of the Mariupol community of the Northern Black Sea Region. This suggests that such funerary practice of the Khvalynsk – Sredni Stog community was formed on the spot, as an internal transformation of the ritual of a stretched-out body with a copious sprinkling of the bone with mineral red paint. The idea of ​​innovation was to set the feet on the ground, which caused the knees to rise.

The consequence for the Proto-Indo-European homeland

So, from now on, when someone says “the oldest known kurgans come from Sredni Stog”, you know what that means: first, these are not the oldest ‘kurgans’, but rather ‘proto-kurgans’ (after, all, some of the first radiocarbon dates of full fledged steppe kurgans come from the Repin culture, if we don’t take the rich Maykop variant into account); and second, they were not really from Sredni Stog, but from Khvalynsk-related cultures, because the first rudimentary kurgans can be clearly traced back to Khvalynsk, Novodanilovka, Northern-Caucasus, and Suvorovo sites.

The latest genetic research on Khvalynsk- and Yamna-related migrations should have been a party for all involved in a quest to know the truth about Proto-Indo-Europeans, as it is becoming clear that their language and culture expanded from the eastern Pontic-Caspian steppe. This is a short checklist of relevant facts:

✅ Khvalynsk formed from EHG + local steppe Neolithic groups: checked.

✅ Kurgan origins and expansion from Khvalynsk: checked.

✅ Expansion of horse domestication and horse symbolism from Khvalynsk: checked.

✅ Arrival of steppe ancestry in the Balkans with Suvorovo: checked.

✅ Patrilineal clans proven by Y-DNA bottlenecks in Khvalynsk and Yamna: checked.

✅ Homogeneous genetic admixture of expanding Yamna: checked.

✅ Admixture different from Yamna in coetaneous West and Central European, Corded Ware, Fennoscandian, Caucasus, and Indus Valley samples: checked.

✅ Expansion of Khvalynsk as Early Yamna and Afanasevo: checked.

✅ Expansion of Yamna Hungary as East Bell Beakers: checked.

✅ Y-DNA bottlenecks of expanding Bell Beakers: checked.

✅ Expansion of East Yamna (and admixture with CWC) in Sintashta/Potapovka: checked.

✅ Y-DNA bottlenecks of expanding Andronovo/Srubna: checked.

✅ Yamna in the Balkans and steppe ancestry in Mycenaeans (in contrast with Minoans): checked.

✅ Bell Beaker expansion over Europe and later resurge of R1a-Z645 in Central-East Europe: checked.

All this combined is giving a clear-cut image of how Proto-Indo-Europeans expanded. More importantly, it shows – as I have said many times already – that Proto-Indo-European was a real language, spoken by an evolving and expanding community (with radical language changes beautifully coupled with archaeological expansions). The implications of this are huge, if only because we can finally get rid of all naysayers in linguistics and archaeology, who wanted to speak about ‘constellations of languages’ and ‘pots not people’.

So why would some of those who describe themselves as interested in Prehistory not accept this as the most likely picture right now? I can just think of one tiny item of the checklist, among many that are left unchecked or have been unchecked due to the latest genetic research:

❌ ‘MY haplogroup’ was involved in the expansion of ‘MY people’: Unchecked.

It is not just that this isn’t checked. It was checked by many in the 1990s and in the 2000s, and some stupid magical meaning was attributed to it. But now it has been unchecked for most Europeans, and this has caused an absurd unrest among some of them, who are now joining those who already opposed mainstream theories (e.g. supporters of the Anatolian homeland, the Iran homeland, the Indus Valley homeland, etc.) with a common aim: to spread reactionary views against the mainstream theories.

If all samples from Khvalynsk, Yamna, Afanasevo, and Bell Beaker had been R1a-Z645; most European Neolithic samples had shown R1b-L23 subclades; and results from Sredni Stog, Corded Ware and part of the Indo-Iranian community were of haplogroup N1c-L392 (although eventually R1a-Z645 had expanded with Indo-Iranians)… Would these people doubt all those facts from the checklist? I don’t think so.
