Differences in ADMIXTURE between Khvalynsk/Yamna and Sredni Stog/Corded Ware


Looking for differences among steppe cultures in Genomics is like looking for a needle in a haystack.

It means, after all, looking for differences among closely related cultures, such as between South-Western and North-Western Anatolian Neolithic cultures, or among Old European cultures (such as Vinča or Cucuteni–Trypillia), or between Iberian cultures after the arrival of steppe-related populations.

These differences between closely related regions, in all these cases and especially among steppe cultures, even when they are supported by Archaeology and anthropological models of migration (and compatible with linguistic models), are expected to be minimal.

Fortunately, we have phylogeography, which helps us point in the right direction when assessing potential migrations using genomic data.

User Tomenable recently pointed out a curious finding on Anthrogenica, from data available in Mathieson et al (2017): in ADMIXTURE results with K=12, a different ancestral component (in light green in the paper, see below) is traceable from the North Caspian steppe since the Neolithic. This is also partially distinguishable on K=10 and K=11, although not so clearly differentiating among later cultures.

NOTE: Read more on the controversy regarding the ideal number of ancestral populations, the absurd use of ADMIXTURE to solve language questions, and the meaning of cross-validation (CV) values

Unsupervised ADMIXTURE plot from k=10 to 12, on a dataset consisting of 1099 present-day individuals and 476 ancient individuals. We show newly reported ancient individuals and some previously published individuals for comparison.

Explanations for this finding might include, as the user points out, a greater contribution of CHG ancestry in the eastern steppe cultures (Khvalynsk/Yamna) compared to the North Pontic steppe (Sredni Stog/Corded Ware), which is probably one of the main genomic differences among both cultures, as I pointed out in the Indo-European demic diffusion model (see accounts on the origins of Khvalynsk and Sredni Stog populations and on contacts between Yamna and the Caucasus, and see below also my sketch of Eurasian genomic history).

Interesting is also the appearance of similar ancestral components later in Vučedol – which probably received admixture from Yamna settlers (see admixture components in West Yamna samples and in the Yamna settler from Bulgaria) – , and later still in the Balkans.

On the other hand, previous ancestral components in outliers from the Balkans seem to be more similar to Sredni Stog samples, giving still more strength to the hypothesis that this common (“steppe”) component expanded westward within the Pontic-Caspian steppe with the spread of Suvorovo-Novodanilovka chiefs.

Problems with this interpretation include:

1) The scarce samples available, the different cultures included, and the CV values of the K populations selected in ADMIXTURE.

2) The lack of data for comparison with Bell Beaker peoples (from Olalde et al. 2017).

3) The sample classified as Latvia_LN/CWC has this component. I have already said before that, given the differences with all other Corded Ware samples, this quite early sample might be an outlier, with Khvalynsk/Yamna population connected directly to the ancestors of this individual, possibly through exogamy (as it is clear from my sketch below). Whether or not this is an outlier among CWC populations in the Baltic, only future samples can tell.

4) Three later individuals from Corded Ware in Germany have the component, in a minimal amount. I would bet – judging by their position in the graphic – that this might be explained through the Esperstedt family. These individuals might have in turn got the contribution directly from the oldest member, who shows what seems (in PCA) like a recent admixture from contemporary steppe cultures (such as the Catacomb culture).

NOTE: See my graphics with interesting members of the Espersted family marked: ADMIXTURE and PCA (outlier).

Tentative sketch modelling the genetic history of Europe and West Eurasia from ancient populations up to the Neolithic, according to results in recent genetic papers and archaeological models of known migrations.

Again, needle in a haystack… And confirmation bias by me, indeed.

But interesting nonetheless.

EDIT (4 JAN 2017): A reader points out that the interpretation of Unsupervised ADMIXTURE should work backwards (i.e. different contributions into different modern populations), and not based solely on ancestral populations, which seems probably right. So again, confirmation bias (and potentially wrong direction fallacy) by me…


Genomic history of Northern Eurasians includes East-West and North-South gradients


Open Access article on modern populations (including ancient samples), Between Lake Baikal and the Baltic Sea: genomic history of the gateway to Europe, by Triska et al., BMC Genetics 18(Suppl 1):110, 2017.


The history of human populations occupying the plains and mountain ridges separating Europe from Asia has been eventful, as these natural obstacles were crossed westward by multiple waves of Turkic and Uralic-speaking migrants as well as eastward by Europeans. Unfortunately, the material records of history of this region are not dense enough to reconstruct details of population history. These considerations stimulate growing interest to obtain a genetic picture of the demographic history of migrations and admixture in Northern Eurasia.

We genotyped and analyzed 1076 individuals from 30 populations with geographical coverage spanning from Baltic Sea to Baikal Lake. Our dense sampling allowed us to describe in detail the population structure, provide insight into genomic history of numerous European and Asian populations, and significantly increase quantity of genetic data available for modern populations in region of North Eurasia. Our study doubles the amount of genome-wide profiles available for this region.

We detected unusually high amount of shared identical-by-descent (IBD) genomic segments between several Siberian populations, such as Khanty and Ket, providing evidence of genetic relatedness across vast geographic distances and between speakers of different language families. Additionally, we observed excessive IBD sharing between Khanty and Bashkir, a group of Turkic speakers from Southern Urals region. While adding some weight to the “Finno-Ugric” origin of Bashkir, our studies highlighted that the Bashkir genepool lacks the main “core”, being a multi-layered amalgamation of Turkic, Ugric, Finnish and Indo-European contributions, which points at intricacy of genetic interface between Turkic and Uralic populations. Comparison of the genetic structure of Siberian ethnicities and the geography of the region they inhabit point at existence of the “Great Siberian Vortex” directing genetic exchanges in populations across the Siberian part of Asia.

f3 values to estimate (a) Eastern European Hunter-Gatherer, b Neolithic Farmer, c Caucasus hunter-gatherer, and d) Mal’ta (Ancient North Eurasian) ancestry in modern humans

Slavic speakers of Eastern Europe are, in general, very similar in their genetic composition. Ukrainians, Belarusians and Russians have almost identical proportions of Caucasus and Northern European components and have virtually no Asian influence. We capitalized on wide geographic span of our sampling to address intriguing question about the place of origin of Russian Starovers, an enigmatic Eastern Orthodox Old Believers religious group relocated to Siberia in seventeenth century. A comparative reAdmix analysis, complemented by IBD sharing, placed their roots in the region of the Northern European Plain, occupied by North Russians and Finno-Ugric Komi and Karelian people. Russians from Novosibirsk and Russian Starover exhibit ancestral proportions close to that of European Eastern Slavs, however, they also include between five to 10 % of Central Siberian ancestry, not present at this level in their European counterparts.

Admixture proportions in studied populations, K = 6. Populations from the Extended dataset. Abbreviated population codes: NSK – Russians from Novosibirsk; STV -Starover Russians; ARK: Bashkirs from Arkhangelskiy district; BRZ – Bashkirs from Burzyansky district

Our project has patched the hole in the genetic map of Eurasia: we demonstrated complexity of genetic structure of Northern Eurasians, existence of East-West and North-South genetic gradients, and assessed different inputs of ancient populations into modern populations.

More evidence on the recent arrival of haplogroup N and gradual replacement of R1a lineages in North-Eastern Europe


A new article (in Russian), Kinship Analysis of Human Remains from the Sargat Mounds, Baraba forest-steppe, Western Siberia, by Pilipenko et al. Археология, этнография и антропология Евразии Том 45 № 4 2017, downloadable at ResearchGate.


We present the results of a paleogenetic analysis of nine individuals from two Early Iron Age mounds in the Baraba forest -teppe, associated with the Sargat culture (fi ve from Pogorelka-2 mound 8, and four from Vengerovo-6 mound 1). Four systems of genetic markers were analyzed: mitochondrial DNA, the polymorphic part of the amelogenin gene, autosomal STR-loci, and those of the Y-chromosome. Complete or partial data, obtained for eight of the nine individuals, were subjected to kinship analysis. No direct relatives of the “parent-child” type were detected. However, the data indicate close paternal and maternal kinship among certain individuals. This was evidently one of the reasons why certain individuals were buried under a single mound. Paternal kinship appears to have been of greater importance. The diversity of mtDNA and Y-chromosome lineages among individuals from one and the same mound suggests that kinship was not the only motive behind burying the deceased people jointly. The presence of very similar, though not identical, variants of the Y chromosome in different burial grounds may indicate the existence of groups such as clans, consisting of paternally related males. Our conclusions need further confi rmation and detailed elaboration. Keywords: Paleogenetics, ancient DNA, kinship analysis, mitochondrial DNA, uniparental genetic markers, STR-loci, Y-chromosome, Baraba forest-steppe, Sargat culture, Early Iron Age.

From the older study of the same region (Baraba, numbered 4) “Location of ancient human groups with a high frequency of mtDNA haplogroups U5, U4 and U2e lineages. The area of Northern Eurasian anthropological formation is marked by yellow region on the map (References: 1. Bramanti et al., 2009; 2. Malmstrom et
al., 2009; 3. Krause et al., 2010; 4. this study)”

Chronological time scale of Bronze Age Cultures from the Baraba region
This is the same team that brought an ancient mtDNA study of different cultures within the Baraba steppe-forest region (from the Open Access book Population Dynamics in Prehistory and Early History).

The Baraba steppe-forest is a region between the Ob and Irtysh rivers (about 800 km from west to east), stretching over 200 km from the taiga zone in the north to the steppes in the south.

The new study brings a more recent picture of the region, from the Iron Age Sargat culture, ca. 500 BC – 500 AD, with five samples of haplogroup N and two samples of haplogroup R1a.

R1a lineages in the region probably derive from the previous expansion of Andronovo and related cultures, which had absorbed North Caspian steppe populations and their Late Indo-European culture.

N subclades prevalent in certain modern Eurasian populations are probably derived from the expansion of the Seima-Turbino phenomenon.

While samples are scarce, Y-DNA data keeps showing the same picture I have spoken about more than once:

N subclades (potentially originally speaking Proto-Yukaghir languages) gradually replacing haplogroup R1a (originally probably speaking Uralic languages), probably through successive founder effects (such as the bottlenecks found in Finland), which left their Uralic culture and ethnolinguistic identification intact.

Therefore, late Corded Ware groups of North-Eastern Europe (in the Forest Zone and the Baltic), mainly of R1a-Z645 subclades, probably never adopted Late Indo-European languages.


Prehistoric loan relations: Foreign elements in the Proto-Indo-European vocabulary


An interesting ongoing web project, Prehistoric loan relations, on potential loans of Proto-Indo-European words, from Uralic-Yukaghir, Caucasian, and Middle Eastern influence.

Based on a Ph.D. thesis by Bjørn (2017) Foreign elements in the Proto-Indo-European vocabulary (PDF).

From the website (emphasis mine):

This page allows historical linguists to compare and scrutinize proposed prehistoric lexical borrowings from the perspective of Proto-Indo-European. The first entries are all (135 in total) extracted from my master’s thesis “Foreign elements in the Proto-Indo-European vocabulary” (Bjørn 2017). Comments are encouraged at the bottom of each entry. New entries will be added, also on request.

Take this not as the conclusion, but an invitation to join the conversation.

So, we welcome the invitation, and hope that this new project thrives.

Also, I loved his fantasy-like map of the central Eurasian region (featured image on this post).


The renewed ‘Kurgan model’ of Kristian Kristiansen and the Danish school: “The Indo-European Corded Ware Theory”

Allentoft Corded Ware

A popular science article on Indo-European migrations has appeared at Science News, entitled How Asian nomadic herders built new Bronze Age cultures, signed by Bruce Bower. While the article is well-balanced and introduces new readers to the current status quo of the controversy on Indo-European migrations – including the opposing theories led by Kristiansen/Anthony vs. Heyd – , it reverberates yet again the conclusions of the 2015 Nature articles on the subject, especially with its featured image.

I have argued many times why the recent ‘Yamnaya -> Corded Ware -> Bell Beaker’ migration model is wrong, mainly within my essay Indo-European demic diffusion model, but also in articles of this blog, most recently in the post Correlation does not mean causation: the damage of the ‘Yamnaya ancestral component’, and the ‘Future America’ hypothesis). It is known that Nature is a bit of a ‘tabloid’ in the publishing industry, and these 2015 articles offered simplistic conclusions based on a wrong assessment of archaeological and linguistic data, in search for groundbreaking conclusions.

An excerpt from Bower’s article:

Corded Ware culture emerged as a hybrid way of life that included crop cultivation, breeding of farm animals and some hunting and gathering, Kristiansen argues. Communal living structures and group graves of earlier European farmers were replaced by smaller structures suitable for families and single graves covered by earthen mounds. Yamnaya families had lived out of their wagons even before trekking to Europe. A shared emphasis on family life and burying the dead individually indicates that members of the Yamnaya and Corded Ware cultures kept possessions among close relatives, in Kristiansen’s view.

“The Yamnaya and the Corded Ware culture were unified by a new idea of transmitting property between related individuals and families,” Kristiansen says.

Yamnaya migrants must have spoken a fledgling version of Indo-European languages that later spread across Europe and parts of Asia, Kristiansen’s group contends. Anthony, a longtime Kristiansen collaborator, agrees. Reconstructed vocabularies for people of the Corded Ware culture include words related to wagons, wheels and horse breeding that could have come only from the Yamnaya, Anthony says.

I have already talked about Kristiansen’s continuation of Gimbutas’ outdated ideas: we are seeing a renewed effort by some Scandinavian (mainly Danish) scholars to boost (and somehow capitalise) the revitalised concept of the “Kurgan people”, although now the fundamental issue has been more clearly shifted to the language spoken by Corded Ware migrants.

As far as I can tell, this renewed interest began two years ago, with the simultaneous publication of genetic studies by Haak et al. (2015), and Allentoft et al. (2015), and the misuse of the cursed concept of ‘Yamnaya ancestry‘ to derive far-fetched conclusions.

On the other hand, genetic research is not solely responsible for this: David Anthony – who was apparently consulted by Haak et al. (2015) for their paper, where he appears as co-author – has kept a low (or lower) profile, and only recently has he merely suggested potential links between Corded Ware and Bell Beaker cultures in Lesser Poland, that might explain what (some geneticists have told him) appeared as a potential Yamna -> Corded Ware -> Bell Beaker migration in the first ancient samples studied.

Anthony’s migration model remains otherwise strongly based on Archaeology, offering a careful interpretation of potential contacts and migrations in the Pontic-Caspian steppe, and only marginally offers some views on Linguistics (based on Ringe’s controversial ‘glottochronological model’ of 2006), to the extent that he is compelled to explain the potential adoption of Indo-European by Corded Ware culture (CWC) peoples as multiple cultural diffusion events, since no migration is observed from the steppe to CWC territories.

I think he is thus showing a great deal of restraint, not jumping on the bandwagon of this recent trend based on scarce genetic finds – and therefore losing also the opportunity to publish articles in journals of high impact factor….

This newly created Danish school, on the other hand, seems to be swimming with the tide. Kristiansen, known for his controversial ‘universal’ interpretations of European Prehistory – which are nevertheless more readable and interesting than most specialised literature on Archaeology, at least for us non-archaeologists – , has apparently seized the opportunity to give a strong impulse to his theories.

Not that there is nothing wrong with that, of course, but sometimes it might seem that a lot of papers (or even researchers) support something, when in fact there are only a few of them, working closely together

I see therefore three main “branches” of this support (two of them, Genetics and Linguistics, only recently giving some limited air to this dying hypothesis), with a closely related group of people involved in this model, and they are lending continuous support to each other, by repeating the same theory – and repeating the same misleading map images (like the one shown in the article) – , so that the circular reasoning they represent is concealed behind seemingly independent works.

The theory and its development

The main theory is officially rooted then in Kristiansen’s hypothesis, whose first article on the subject seems to be Prehistoric Migrations – the Case of the Single Grave and Corded Ware Cultures (1989), supporting the Kurgan model applied to the Corded Ware migrations. It was probably a kind of a breakthrough in Archaeology, bringing migration to mainstream Archaeology again (followed closely by Anthony), and he deserves merit for this.

After this proposal, there are mostly just his publications supporting this model. Nevertheless, Kristiansen’s model, I gather, did not involve the sudden Yamnaya -> Corded Ware migrations discussed in recent genetic articles, but long-lasting contacts between peoples and cultures from the North Pontic steppe, Trypillian, and Globular Amphora, that formed a new mixed one, the Corded Ware people and culture. Also, in Gimbutas’ original model of migration (1963), waves of Kurgan migrants are also described into Vučedol and Bell Beaker, which have been apparently forgotten in recent models*.
* The most recent model by Anthony describes such migrations into Early Bronze Age Balkan cultures – as do most archaeological publications today – , but he is unable to recognize migration waves from Yamna into the Corded Ware culture, and because of that describes mere potential routes (or modes) of cultural diffusion including language change.

Proposal for the origin and spread of the Corded Ware/ Battle Axe cultural complex: 1) Distribution of CWC groups; 2) Yamna culture; 3) presumed area of origin; 4) presumed main directions of the primary distribution. Also numbered are other individual CW cultures. From Kristiansen (1989).

Then – skipping the years of simplistic phylogeography based on modern haplogroup distribution – we have to jump directly to Allentoft (of the Natural History Museum of Denmark) and cols. and their article on population genomics of Bronze Age Eurasia (2015), with which Kristiansen collaborated, and which offers the first direct association of Corded Ware as the vector of expansion of Indo-European peoples and languages from Yamna. An interesting take on the Yamna -> Corded Ware -> Bell Beaker question is represented by their very ‘kurgan-like’ Corded Ware-centric map:

Detail of Fig. 1 from Allentoft et al. (2015): “Distribution of Early Bronze Age cultures Yamnaya, Corded Ware, and Afanasievo with arrows showing the Yamnaya expansions”.

And suddenly, we are now seeing more works that support the central thesis of the group – that Corded Ware must have brought Indo-European languages to Europe:

Recent publications by K-G Sjögren – from the same department as Kristiansen, at the University of Gothenburg – seem to imply that there was a direct connection Corded Ware -> Bell Beaker in central Europe.

Guus Kroonen‘s recent hypothesis of a potential (Proto-Semitic-like) Germanic substrate (2012) has been added recently to the cause, in supporting with Iversen (also from the University of Copenhaguen) a link with the Battle Axe/Funnelbeaker culture interaction. However, in the archaeological-linguistic model it seems that Germanic must predominate over the rest of Indo-European languages in terms of age, representing the first wave of Indo-Europeanization in Europe (wat?!), whereas Balto-Slavic is much younger and unrelated…? But didn’t they share the same substrate (as did partially Greek) in Kroonen (2012)? I think Kroonen’s hypothesis might be better explained through an earlier contact in the North Pontic steppe

Modified from Kristiansen et al. (2017). “Schematic representation of how different Indo-European branches have absorbed words (circles) from a lost Neolithic language or language group (dark fill) in the reconstructed European linguistic setting of the third millennium BC, possibly involving one or more hunter gatherer languages (light fill) (after Kroonen & Iversen 2017)”.


This recently created Danish pressure group is not something bad per se. I don’t agree with their hypothesis (or rather evolving hypotheses, since they change with new genetic results and linguistic proposals, as is shown in Kristiansen et al. 2017), but I understand that the group continues a recent tradition:

Publications are always great to advance in knowledge, and if they bring some deal of publicity, and more publications (with the always craved impact factor), and maybe more investment in the departments (with more local jobs and prestige)… why not?

However, this model of workgroup research system is reminiscent of the Anatolian homeland group loosely created around Renfrew; the Palaeolithic Continuity workgroup around Cavalli-Sforza; or (more recently) the Celtic from the West group around Cunliffe and Koch. The difference between Kristiansen’s workgroup and supporters of all those other models, in my opinion, is that (at least for the moment) their collaboration is not obvious to many.

Therefore, to be fair with any outsider, I think this group should clearly state their end model: I propose the general term “Indo-European Corded Ware Theory” (IECWT) workgroup, because ‘Danish’ is too narrow, and ‘Scandinavian’ too broad to represent the whole group. But any name will do.

My opinion on the IECWT

As you can see, no single strong proof exists in support of the IECWT:

  • Not for a solid model of PIE expansion from Corded Ware, not even within the IECWT group, where there is no support (to date) for a Balto-Slavic expansion associated with the Corded Ware culture… Or any other dialect, for that matter;
  • Not for a Corded Ware -> Bell Beaker connection – that is, before the publication of Allentoft et al. (2015) and articles reverberating their conclusions;
  • Not for a unified Pre-Germanic community before the Dagger Period, and still less linked with the expansion of the Corded Ware culture from the steppe – that connection is found only in Anthony (2007), where he links it with a cultural diffusion into Usatovo, which seems too late for a linguistic expansion with Corded Ware peoples, with the current genetic data.

The wrong interpretation of scarce initial ancient samples has been another feeble stone put over the ruins of Gimbutas’ theory. While her simple theory of Kurgan invaders was certainly a breakthrough in her time – when speaking about migrating Indo-European peoples was taboo -, it has since been overcome by more detailed archaeological and linguistic accounts of what happened in east and central Europe during the Chalcolithic and Bronze Age.

However, a lot of people are willing to consume post-truth genetic-based citebait like crazy, in a time when Twitter, Facebook, blogs, etc. seem to shape the general knowledge, while dozens of new, carefully prepared papers on Archaeology and Linguistics related to Indo-European peoples get published weekly and don’t attract any attention, just because they do not support these simplistic claims, or precisely because they fully reject them.

An older connection of Germanic to Scandinavia – and thus an ancestral Indo-European cultural diffusion from north to south – seems to better fit the traditional idea of an autochthonous Germanic homeland in Scandinavia, instead of a bunch of southern Bell Beaker invaders bringing the language that could only later develop as a common Nordic language during the Bronze Age, in a genetically-diverse community…

One is left to wonder whether the support of Corded Ware + haplogroup R1a representing Pre-Germanic is also in line with the most natural human Kossinnian trends, whereby the older your paternal line and your ancestral language are connected to your historical territory, the better. The lack of researchers from Norway – where R1b subclades brought by Bell Beakers peak – in the workgroup is revealing.

Just as we are seeing strong popular pressure e.g. to support the Out of India Theory by Hindu nationalists, or some Slavic people supporting to recreate a ‘Northern IE group’ with a Germano-Balto-Slavic Corded Ware culture – and a renewed interest in skin, hair and eye colour by amateur geneticists – , it is only natural to expect similar autochtonous-first trends in certain regions of the Germanic-speaking community.

NOTE: I feel a bit like an anti-IECWT hooligan here, and once again fulfilling Godwin’s Law. Judging by previous reactions in this blog to criticism of the Out of India Theory, and to criticism of R1a as the vector of expansion of Indo-European languages, this post is likely to cause some people to feel bad.

It is not intended to be against these researchers individually, though. All of them have certainly contributed in great ways to their fields, indeed more than I have to any field: Kristiansen is well-known for his careful, global interpretations of European prehistory (and has been supporting his model for quite a long time). I do like Kroonen’s ideas of a Pre-Germanic substratum. And people involved in the group do so probably because they collaborate closely with each other, and because of the huge pressure to publish in journals of high impact factor, so to mix their disparate research within a common model seems only natural.

But their collaboration is boosting certain wrong ideas, and is giving way to certain misconceptions in Linguistics, and also sadly renewed past ethnocentric views of language in Northern Europe – that will be luckily demonstrated, again, wrong. After all, publications (like ideas in general) are subjected to criticism, as mine are. Researchers who publish know their work is subjected to criticism, and not only before publication, but also – and probably more so – after it. That a paper can be incorrect, biased, or even completely absurd, does not mean the person who wrote it is a fool. That’s the difference between criticising ideas and insulting. If criticism offends you, you shouldn’t be publishing. Period.

Indo-European demic diffusion model, 3rd Ed. – Revised October 2017


I have just uploaded a new working draft of the third version of the Indo-European demic diffusion model.

In this new version I have added more information published recently, I have updated the maps – especially the one on Palaeolithic migrations -, I have added information on Sredni Stog and its potential role in developing the Corded Ware culture and most likely language, and I have corrected certain parts that have become obsolete, especially after the latest version (19 Sept. 2017) of Mathieson et al. (2017).

It can be read or downloaded at:

Included is my first sketch of the genetic history of Europe, as I interpret it in light of Genetic research (especially from outputs of qpGraph published to date), but also Archaeology (and, to some extent, Linguistics).

Tentative sketch modelling the genetic history of Europe and West Eurasia from ancient populations up to the Bronze Age, according to results in recent Genetic papers and archaeological models of known migrations.

I have also taken this opportunity to upload some drafts I had been preparing in September while working on the Third Edition, that I have sadly not been able to complete as I would have wanted to. The drafts are posted in the section Human Ancestry. I post them as they are, in the hope that they can help others.
