Another hint at the role of Corded Ware peoples in spreading Uralic languages into north-eastern Europe, found in mtDNA analysis of the Finnish population

corded-ware-migration-yamna

Open article at Scientific Reports (Nature): Identification and analysis of mtDNA genomes attributed to Finns reveal long-stagnant demographic trends obscured in the total diversity, by Översti et al. (2017).

Of special interest is its depiction of Finland’s past as including the expansion of Corded Ware population of mtDNA U5b1b2 (and probably Y-DNA R1a-M417 subclades), most likely Uralic speakers of the Forest Zone, to the north of the Yamna culture (where Late Proto-Indo-European was spoken).

A later expansion of other subclades – particularly Y-DNA N1c -, was probably associated with the later western expansion of the Eurasian Seima-Turbino phenomenon, and its current prevalence in Finnish Y-DNA haplogroups might have been the consequence of the population decline ca. 1500 BC, and later Iron Age population bottleneck (with the population peak ca. 500 AD) described in the article.

That would more naturally explain the ‘cultural diffusion’ of Finnic languages into invading eastern N1c lineages, a diffusion which would have been in fact a long-term, quite gradual replacement of previously prevalent Y-DNA R1a subclades in the region, as supported by the prevalent “steppe” component in genome-wide ancestry of Finns.

Therefore, there were probably no sudden, strong population (and thus cultural) changes associated with the arrival of N1c lineages, like the ones seen with R1a (Corded Ware / Uralic) and R1b (Yamna / Proto-Indo-European) expansions in Europe.

How the Saami fit into this scheme is not yet obvious, though.

Abstract:

In Europe, modern mitochondrial diversity is relatively homogeneous and suggests an ubiquitous rapid population growth since the Neolithic revolution. Similar patterns also have been observed in mitochondrial control region data in Finland, which contrasts with the distinctive autosomal and Y-chromosomal diversity among Finns. A different picture emerges from the 843 whole mitochondrial genomes from modern Finns analyzed here. Up to one third of the subhaplogroups can be considered as Finn-characteristic, i.e. rather common in Finland but virtually absent or rare elsewhere in Europe. Bayesian phylogenetic analyses suggest that most of these attributed Finnish lineages date back to around 3,000–5,000 years, coinciding with the arrival of Corded Ware culture and agriculture into Finland. Bayesian estimation of past effective population sizes reveals two differing demographic histories: 1) the ‘local’ Finnish mtDNA haplotypes yielding small and dwindling size estimates for most of the past; and 2) the ‘immigrant’ haplotypes showing growth typical of most European populations. The results based on the local diversity are more in line with that known about Finns from other studies, e.g., Y-chromosome analyses and archaeology findings. The mitochondrial gene pool thus may contain signals of local population history that cannot be readily deduced from the total diversity.

From its results:

In general, there appears to be two loose and largely overlapping clusters among the Finn-characteristic haplogroups: the first between 1,000–2,000 ybp and the second around 3,300–5,500 ybp. The age of the older cluster coincides temporally with the arrival of the Corded-Ware culture and, notably, the spread of agriculture in Finland. The arrival and spread of agriculture, temporally corresponding with the age estimates for most of the haplogroups characteristic of Finns, might be a sign of population size increase enabled by the new mode of subsistence, resulting in reduced drift and accumulation of genetic diversity in the population.

(…)

Another insight in the past population sizes in Finland is based on radiocarbon-dated archaeological findings in different time periods. These analyses suggest two prehistoric population peaks in Finland, the Stone Age peak (c. 5,500 ybp) and the Metal Age peak (~1,500 ybp). Both of these peaks were followed by a population decline, which appears to have reached its ebb around 3,500 ybp. These developments are not distinguishable in the BSPs. However, these ages correspond well to the two haplogroup age clusters described above. The presumably less severe Iron Age population bottleneck seen in the archaeological data, 1,500–1,300 ybp, temporally coincides with the population size reduction visible for the Finn-characteristic subhaplogroups.

Germanic–Balto-Slavic and Satem (‘Indo-Slavonic’) dialect revisionism by amateur geneticists, or why R1a lineages *must* have spoken Proto-Indo-European

haplogroup-R1a

I feel there has recently been an increase in references to quite old – and generally outdated – terms, such as Germano-Balto-Slavic and “Indo-Slavonic” (i.e. Satem), described as Late Indo-European dialects. This is happening in forums and blogs that deal with “Indo-European genetics”, and only marginally (if at all) with the main anthropological subjects that form Indo-European studies, that is Linguistics and Archaeology.

Firstly, let me go apparently against the very aim of this post, by supporting the common traits that these dialects actually share.

Satem Indo-European or Indo-Slavonic

Balto-Slavic is a complex dialect, whose known proto-history and history offers already a difficult picture. Contrary to the opinion of many, there is no single document that can identify the terms Antes, Sklavenes, and Venedi with the cultures that are usually identified as speaking languages ancestral to East Slavic, South Slavic, and West Slavic . These names were used interchangeably in the Byzantine Empire, which was obviously not involved in classifying Slavic peoples by their linguistic branches… For more on the historical identification of Slavic tribes, read Florin Curta‘s The Making of the Slavs: History and Archaeology of the Lower Danube Region, c. 500-700 A.D. On the identification of potential candidates for early Slavic and Baltic cultures, you can read the appropriate entries in the Encyclopedia of Indo-European Culture, by Mallory & Adams.

Baltic and Slavic tribes seem to have a too recently recorded history to be able to confidently trace back their cultural predecessors. In its recent history, close to the formation of its community, Proto-Slavic must have had intense contacts with Iranian-speaking peoples. Also, previously, if R1a-M417 subclades are in fact the most common lineages expanded with the Corded Ware culture (as it seems now), they have no doubt shared a common language, most likely a non-Indo-European one. Not Indo-European in the strict sense, at least, since it formed part most likely of the Indo-Uralic continuum that must have been spoken during the Mesolithic in Eastern Europe, and a language probably nearer to Uralic than to classic Indo-European.

A strong connection between Balto-Slavic and Indo-Iranian in a common Satem branch, as supported by Kortlandt (see e.g. Balto-Slavic and Indo-Iranian 2016, or a reconstruction of Schleicher’s Fable in PIE branches), would imply that a Corded Ware culture from the Dnieper-Donets – speaking a Graeco-Aryan dialect – interacted for centuries with Uralic and other Graeco-Aryan languages, only later influenced by North-West Indo-European (as late as its contact with East Germanic during the Barbarian migration). This model cannot justify the shared traits of Balto-Slavic with North-West Indo-European, unless a third, substrate language – like Holzer’s (1989) Temematic proposal – is added to the equation. Such models are not impossible, but seem too complex.

On the other hand, linguistically Balto-Slavic seems to have split in its known branches quite early, and traits such as the satemization trend appear to have affected each main dialect (Baltic and Slavic) differently, as attested in the different ruki development, hence the assumption of its early but different influence of the trend to both Indo-Iranian and Balto-Slavic (or, more exactly, Indo-Iranian, Baltic, and Slavic). Also, the common North-West Indo-European vocabulary, as well as morphological trends shared by NW IE dialects, clearly affects the oldest layer of both languages (hence the parent Proto-Balto-Slavic too), which predates thus the satemization trend, and further contributes to the idea of a common root between West Indo-European (or Italo-Celtic), Northern Indo-European (the language ancestral to Pre-Germanic), and Proto-Balto-Slavic.

Germano-Balto-Slavic or North European

A common group between Germanic and Balto-Slavic is justified by the presence of certain common isoglosses, such as the famous shared oblique cases in *-m- instead of *-bh-, and support for such a group is found recently e.g. in Gramkelidze-Ivanov (1993-1994) – who nevertheless support a North-West Indo-European continuum -, or in Jasanoff, for whom both languages (regarding phonological traits) “began their post-IE history together”.

proto-indo-european-language-tree
Proto-Indo-European language tree, including early (Indo-Hittite) and late (European) stages by Trager & Smith (1950). From the paper On the Origin of North Indo-European, Gimbutas (1952)

On the other hand, such shared traits could have derived either from old contacts – supported traditionally because of their proximity -, or by a common substrate to both without a need for direct contacts, as supported by Kortlandt in Baltic, Slavic, Germanic (2016), among others).

The fact that there might have been a different, third language involved – the hypothetic Temematic substrate language to Balto-Slavic, potentially nearer to Baltic because of the stronger superstrate influence in Slavic – further complicates the dialectal identification of Baltic and Slavic – that is, if one supports a common Germanic and Balto-Slavic group.

This Northern group was supported by Gimbutas (1952) based on a previous linguistic paper by Trager & Smith (1950) – published in the infancy of dialectal PIE differentiation -, but this model is not mainstream nowadays. The linguistic model followed by Anthony (based on Ringe, Warnow, and Taylor 2002), did not link Germanic to Balto-Slavic (or to Italo-Celtic, for that sake) more than to any other dialect, but it seems that the three might have spread from the same western (Repin-derived) Yamna region, according to their maps. See for example their recent article The Indo-European Homeland from Linguistic and Archaeological Perspectives, which sums up and partly corrects Anthony’s detailed account of steppe migrations in the already classic book The Horse, the Wheel, and Language: How Bronze-Age Riders from the Eurasian Steppes Shaped the Modern World (2007). Dialectal groups and implications are unclear from their publications, with changing linguistic schemes since 2007, but with a quite stable archaeological framework.

Dialectal Late Indo-European

I am not implying that a common group of Balto-Slavic with Indo-Aryan (or of Germanic with Balto-Slavic) is fully discarded by linguistics: history and archaeology can indeed support a close interaction between these languages, and there has been historically some support to the inclusion of Balto-Slavic within a Graeco-Aryan group. However, Linguistics and Archaeology are each day more supportive of the association of Italo-Celtic with Germanic in a North-West Indo-European group, and Balto-Slavic with them (Oettinger 1997). See for example any recent article or book by Mallory, Adams, Beekes, Adrados, etc., or if you prefer, refer to the mainstream models followed by scholars in the German, Spanish, Leiden, or American schools. As you probably know, Clackson for the British school supports an abstract “constellation analogy” model for the language reconstruction, and the French school is dominated by archaeologist Jean Paul Demoule’s rejection of a Proto-Indo-European community; both schools, as you can imagine, will have to revise their theories in light of recent genetic studies…

Regarding Archaeology, North-West Indo-European must have expanded with the westward Yamna expansion, i.e. associated with the Bell Beaker expansion. That was supported in mainstream Archaeology before the most recent genetic studies.

Even Anthony (2007), who has related the Corded Ware culture to the expansion of Indo-European languages through cultural diffusion, recognizing the expansion of Yamna migrants to the west (identifying them with Italo-Celtic and Proto-Greek speakers), has to offer two or three separate cultural diffusion events (!), whereby Pre-Germanic, Proto-Balto-Slavic, and Proto-Indo-Iranian had been learned by the influence of the Yamna culture on neighbouring (unrelated) peoples of Corded Ware cultures: in Central European – Single Grave culture (from Pre-Germanic Usatovo), Middle Dnieper culture (from Balto-Slavic in the Contact Zone), and Potapovka (from Poltavka) cultures, respectively. No actual spread or migration from Yamna into Corded Ware has been supported since Gimbutas.

Balto-Slavic is indeed a complex group of languages – with some supporting (since Toporov and Ivanov proposal in the 1960s) three dialectal groups, composed of East Baltic, West Baltic, and Slavic branches (thus implying an older split of Baltic). Because of the close interaction of eastern Europe with Eurasian invasions, the nature of their language won’t probably ever be solved. Genetics is not the savior that overcomes these difficulties; so long it has only brought more (albeit no doubt interesting) questions, and even though their correct interpretation might offer some new light, we will be far from obtaining a clear picture of the cultural and linguistic development of Proto-Baltic and Proto-Slavic communities.

What I am criticizing here, therefore, is this recent revisionist trend whereby PIE must have been spoken by R1a-Z645 lineages, a trend found not only among amateur geneticists. I am beginning to think – judging from online comments, posts or tweets – that this trend is becoming stronger as a reaction to the fact that not a single R1a-Z645 sample has been found in Yamna or its expansion. These new revisionist models depict a common group of R1a-Z645 lineages hidden somewhere in the steppe, sharing some sort of Indo-Germanic (??) group, or argue for a shared Late PIE community without dialectal divisions, to justify its potential find somewhere marginal to the PIE territory, and then a later development of Corded Ware into Bell Beaker cultures (and, it is implied, peoples).

While not impossible, these are unlikely models, not based on knowledge but on wishes, since linguistic data strongly suggest a North-West Indo-European dialect including Italo-Celtic, Germanic, and (at the very least in its substrate and thus western R1a lineages) Balto-Slavic, and archaeological findings don’t show any meaningful population exchange between Corded Ware and Yamna… That is, it hadn’t until after the first famous papers on the so-called ‘steppe admixture’ of 2015, when (surprise!) Kristiansen has already jumped on the bandwagon (and Anthony seems to be beginning to suggest the same) of previously discarded Yamna -> Corded Ware, and Corded Ware -> Bell Beaker migrations.

Not a single serious researcher can deny that a hidden community of R1a-417 in Yamna is possible. But no one should support that it is the most likely explanation to the current genetic picture, whether based on Linguistic, Archaeology, Anthropology, or Genetics (be it phylogeography or admixture analyses).

I think this recent trend must therefore be the fruit of the influence of previous, deeply entrenched concepts regarding the Corded Ware culture and its link with Proto-Indo-European. These concepts are based on Gimbutas’ Kurgan model, Anthony’s revision of it – explaining the expansion as multiple cultural diffusions (thus renewing Gimbutas’ claim) -, and early studies of modern populations’ haplogroups. Apart from those trends, especially worrying for the future of the field (if it is to be taken seriously), is the interest of some pressure groups, including especially eastern Slavic peoples of R1a lineages, and Finnic speakers of N1c lineages, who are linking some fantastic ancient ethnolinguistic community to their modern national pride.

Adapting to reality

You can find support for anything you like in anthropology: there is certainly a paper out there that apparently supports your personal view on prehistoric ethnolinguistic Europe. You only have to do a quick search in Academia.edu, and you can justify whatever new genetic results you personally obtained playing with the freely available datasets and open source software – e.g. from Reich’s lab, or the famous ADMIXTURE. If you are one of those few interested in the field who haven’t tried it out yet, Razib Khan helps introduce you to DIY Genetics, so you can show off some graphics and proportions, like most popular bloggers and forum users are doing. Then you can also publish your results in BioRxiv, just to try it out.

So there is no merit at all in justifying these genetic results by supporting a potential anthropological scenario for it. Heck, you can invent it! Here, I said it. Anyone can do Anthropology. In fact, it seems that everyone does Human Evolutionary Genetics nowadays, no matter their background. Some lab knowledge and experience in doctoral research seems to be enough.

Admixture analyses are obtained using one or more algorithms, which have a limited potential to inform of possible migrations (its ultimate objective, at least regarding its complementary function to Archaeology within Indo-European studies). Such algorithms invariably have:

  • Intrinsic constraints: You have to understand each algorithm’s intrinsic limitations to be able to apply them correctly, and to derive meaningful but cautious conclusions. Using software commands and obtaining graphics and percentages does not imply you understand the constraints at stake. If you have tried them out, you have seen their great limitations; if you don’t see them, you certainly realize how little you understand of them.
  • Extrinsic constraints. Most are known, and often mentioned explicitly in research papers:
    • Few DNA samples, from limited sites.
    • Scarce and variable material recovered from these samples.
    • Quality of the retrieval, human errors, etc.
    • Lack of precise anthropological context.

Admixture results (whether by professionals or amateurs) are nevertheless often illustrated with tailored anthropological models: in case of the renown papers most likely because of ignorance of anthropological context, broad (philosophical or theoretic) and precise (historical), or lack of sufficient understanding of the different fields involved, and in case of many amateur geneticists also (often) to justify a desire for a prehistoric ethnolinguistic identification similar to their social or political agendas, in a new Kossinnian trend.

Admixture analyses are not wrong per se. It is wrong to trust them to inform you of something they can’t; because they need context, and ancient samples need ancient context, which in prehistoric times is obviously quite limited. If you don’t know as much as possible about the ancient context (i.e. Linguistics, Archaeology, Anthropology), you get the wrong conclusions. Period. If you look for papers on ancient context expecting to find whichever model fits your results (or worse, your wish), that is called bias. Don’t expect to get the right conclusions doing that, either. If you find it, that’s called confirmation bias. Such results are not useful. For anyone, not even you, you just deceive yourself and maybe others.

Some apparently think that a group of geneticists can achieve a meaningful interpretation of data just by adding one or more archaeologists to the research group – or as ‘co-authors’ of individual research papers. Wrong again. Ten people with IQ 20 don’t make the reasoning of a person with IQ 200 (not that I believe in measuring intelligence, but you get the point). Similarly, twenty researchers, each one with knowledge exclusively (or almost exclusively) of their own field, can’t achieve a meaningful explanation for the data obtained. Geneticists look for an anthropological model that coherently fits their results. Archaeologists will look for a model known to them that fits the genetic results (or more likely the interpretations thereof) they are given. That way, when working together, they can achieve a common ground. If neither of them understands the complexities and shortcomings of the others’ materials and methods (and their whole background), the results will be formally correct, but still wrong. They need to know all aspects involved in the others’ fields in great detail, to understand all potential implications of new data.

Since the advent of ancient DNA samples and especially PCA analyses, phylogeography (leaning predominantly on Y chromosomes) has been relegated to a (probably deserved) second place in assessing DNA samples. However, as Razib Khan states, “in the scaffold of the ancient DNA framework it can resolve some issues”. I think this is one of those issues, an issue that is not trivial at all – in that it affects migration models from the steppe at a critical period of linguistic expansion -, and the shortcomings of not relying on it are becoming quite evident with each new publication.

Many amateur geneticists that support the mainstream genetic models of the past two years don’t like the ad hoc explanations that others have been constantly giving to support their previous theories. After all, it seems unfair that some people would reject data that offers an obvious prehistoric picture of populations, because of the unwillingness to change one’s own preconceptions, right? For example, against the mainstream steppe migration theory, we have those who support that R1b must have been western European (Palaeolithic or Mesolithic) hunter-gatherers expanded from Iberia; or those who want R1a to have expanded from India. No matter how strong the evidence is against those models, some groups harbour a desire to fit anything in one’s previous image of reality.

However, some people who can’t stand those absurd ad hoc explanations and rationalisations, are quite ready to embrace the idea that, somehow, during the Chalcolithic expansion of Yamna, an imaginary community was formed where communities of divergent lineages R1a-Z645 (found mostly north of the steppe and later in Corded Ware cultures) and R1b-M269 (found mostly in the steppe and later in the cultures known to have evolved from Yamna, like Afanasevo, Vučedol, and Bell Beaker) lived together and spoke the same language for centuries, or even millennia. And that community would have existed after a Late Neolithic westward expansion of the Khvalynsk culture, and another westward expansion of the Repin culture, both of which probably reduced the diversity of Y-DNA lineages within Yamna: the first to R1b-M269 lineages, the second to R1b-L23 subclades.

Both communities of R1a and R1b lineages, described then as united until the Yamna expansion (although no sample of R1a-Z645 subclade has been ascribed to any steppe expansion) would have expanded somehow separately, R1a-M417 exclusively to the north into Corded Ware – without any migratory connection found between Yamna and Corded Ware in mainstream Archaeology -, and forming thus dialectal groups (like “Germano-Balto-Slavic” or “Indo-Slavonic”) that are not supported by mainstream linguistics.

On the other hand, R1b-Z2103 and R1b-L51 lineages, which were already separated within Yamna and probably forming different communities, are known to have spread to the west with the Yamna expansion, in some places and cultures they are found together (like Bell Beaker), which would be expected in a common migration of separate groups. No single R1b-L23 sample has been found in the Corded Ware expansion, no single R1a-M417 individual in the Yamna expansion.

These convoluted explanations of how R1a lineages must have spoken Indo-European are based on the assumption that admixture analyses (from the current limited data, with the current wrong interpretation of their context) necessarily means that Corded Ware peoples spread as Yamna migrants – hence R1a lineages must come from Yamna – and then spread into Bell Beaker.

It is possible, and in my opinion expected, that eventually some R1a-M417 subclade will be found in Yamna samples (east or west), and some haplogroup R1b-M269 (especially R1b-L23 and subclades) will be found in samples from Corded Ware cultures (west or east). Indeed, there must have been close contacts between both cultures (between Yamna–Southeast Europe–East Bell Beaker and Corded Ware), and not only through female exogamy. It would be quite strange not to find a single R1b-L23 sample in Corded Ware cultures, or an R1a-M417 sample in Late Proto-Indo-European-speaking territories. Those scattered samples, whenever they are found, will probably not change the data: but they might give a reason for some to keep supporting a model that is not the most likely one. It won’t still be the most reasonable, the simplest model that explains all data.

What it means to be an ‘ethnic’ Balt or Slav

Older models – older even than Gimbutas’ kurgan model of the 1950s, as you can see -, by presupposing an instant breakup of a unitary Proto-Indo-European language into different linguistic communities without previous dialectal relation with each other, cannot explain our common European linguistic heritage. More recent models based on recent genetic studies (and on outdated or newly invented linguistic and archaeological theories), by trying to connect genetically (directly) modern eastern Europeans with Proto-Indo-Europeans, are in fact disconnecting Balto-Slavic peoples from the rest of Europe for three thousand years, and connecting them either with Uralic or with Indo-Iranian speakers. Ethnolinguistic identification, however, is not about genetics – and it has never been, and I hope it will never be -; it is related to self-identification into groups, and more broadly to a common culture, and often specifically a common language.

In terms of language, it makes sense to support a situation where Balto-Slavic was a North-West Indo-European dialect (sharing a common language ancestral to Germanic and Italo-Celtic too), with certain ancient (Uralic?) innovative traits shared with Indo-Iranian and partly with Germanic (but with no direct contacts necessary between these branches). Its recent transition to a Baltic and Slavic proto-languages, already by eastern European groups, shows their strong external influence from Uralic and Iranian, respectively, so an identification of Balto-Slavic with the expansion of R1a lineages is probably to be found in a western group of R1a-Z282 subclades expanding eastwards between the Bronze Age and the Iron Age.

Eastern Europe’s Indo-European heritage (Balto-Slavic) is therefore connected to the western European one (Italo-Celtic and Germanic), each with its own linguistic substrate and influences, but with a common, shared ancient language. North-West Indo-European derived in turn from Late Indo-European, a language ancestral to Indo-Iranian and Palaeo-Balkan languages, the latter showing continued contacts with western Europe for millennia.

In the minimum-case scenario – for supporters of a Satem proto-language like Kortlandt – the language substrate to Baltic and Slavic must be a North-West Indo-European language (to fit its shared traits with North-West Indo-European), like Holzer’s Temematic (a hypothesis which Kortlandt seems to support) that would have then been recently absorbed by Satem speakers of Eastern Europe. In that context, central European R1a-Z282 lineages (which form the majority of West Slavic lineages) would have spoken that NWIE language for millennia , until proto-historic times, when a cultural diffusion of a Graeco-Aryan dialect (mainly spoken by R1a-Z93 or eastern European R1a-Z282 lineages, then) would have happened in eastern Europe, and then a cultural diffusion (or demic diffusion?) of Slavic-speaking peoples would have happened to the west, into central Europe.

In none of these scenarios is any sort of Proto-Indo-European -> Balto-Slavic ethnolinguistic, genetic, or territorial continuity to be seen. The former model is not only the simpler explanation for Slavic and Baltic, but it is also the communis opinio today by most Indo-Europeanists, it is supported by Archaeology, and Genetics is likely to keep supporting it with each new paper. I don’t find anything shameful, or that could diminish modern Baltic and Slavic identities a bit, by accepting any of those models, so I don’t understand the imperative need some people seem to have of identifying R1a lineages with the Yamna expansion and thus Proto-Indo-European.

For those who will still be vying for a more prominent role of haplogroup R1a in the Proto-Indo-European ethnogenesis, there are alternative older scenarios to the arrival of Proto-Indo-European to the steppe, as there are older models for an Anatolian origin of PIE. So, for example I already laid out the possibility that the invasion of R1a-M417 brought Indo-European (or, more precisely, Indo-Uralic) to eastern Europe – as part of a Uralo-Yukaghir or Paleo-Siberian group -, while R1b communities may have originally been speakers of Afroasiatic (cf. R1b-V88 and the potential Afroasiatic homeland in Lake Megachad), and R2 would have been associated with the spread of Dravidian (and maybe Kartvelian and Altaic), all of them departing from a common Nostratic associated with haplogroup R. This model could find support in genetics in the link found between Mesolithic Northeast Europeans and Neolithic Siberians, from an Ancient North Eurasian (ANE) population probably rich in Y-chromosome haplogroup R1a.

This is just one of many highly hypothetic ancient scenarios, and it requires more assumptions than a continuity of Indo-Uralic (or even Indo-Uralic and Afroasiatic) with R1b lineages – R1a potentially marking the spread of Paleo-Siberian languages -, and above all it is based on controversial linguistic macrofamilies, not (yet?) supported by mainstream anthropological disciplines. It is nevertheless one theory certain romantics can place their hopes in, as R1b communities of the steppe become accepted as those originally speaking (Middle and Late) Proto-Indo-European in the steppe.

Wrap-up

I am not saying I am right. There is still too much to be said and corrected. In fact, I could be wrong, and we may lack a lot of interesting data: there might have been a late R1a-R1b North-West Indo-European-speaking community within western Yamna, and we might need to revise what we knew about Archaeology yet again (and maybe even Linguistics!) before admixture algorithms; then maybe geneticists have come to save the day after all. However, all anthropological evidence points strongly (and genetic studies more strongly with each new study) to the image we had previous to the first genetic data based on haplogroups.

I think it is preposterous of some researchers (no matter if professional or amateur geneticists, or archaeologists, or even linguists) to think algorithms can beat more than two hundred years and thousands of works on this matter. In Academia, mathematics rarely revolutionize a field; it could usually help, but it can just make you sound scientifish, and point in the wrong direction.

And no, I am not smarter than the rest, I can only judge from what I know, and that is always too little, far less than I would like to. But maybe I am in a more neutral position regarding the end result, given my renewed skepticism in revolutionary methods to solve academic problems, and my indifference as to a western European or eastern European origin of R1b or R1a lineages. And I am not alone in my lack of confidence in the interpretation of recent genetic admixture results – read Voker Heyd’s papers, for example, if you want the view of a renown and experienced archaeologist who was in the field of Indo-European studies earlier than any of those now popular geneticists.

In fact, I also fell for the R1a-Corded Ware expansion of Late Indo-European, and before many in the Anthropological fields, and with even less proof, back when we only had haplogroups of modern populations and the promises of Cavalli-Sforza. When I decided to publish a grammar to learn Indo-European as a modern language, the aim was to offer a mainstream reconstruction of Late Proto-Indo-European without adding my own contributions; despite this, I added the newly, archaeogenetically-supported Corded Ware migration model (see A Grammar of Modern Indo-European, Third Edition, pp. 74 and ff.).

I guess I liked the picture of an old romantic Europe, divided in western Vasconic (R1b) and eastern Uralic (N1c) hunter-gatherers (and later farmers) being invaded by warring kurgan-makers from the steppe (R1a) … And I really liked the article of Haak et al. (2015) – the first one I read on this subject -, which I saw, like everyone else, as supporting what many of us already believed about a single, common expansion of North-West Indo-European into western Europe. It also made our life – regarding the linguistic unity of Balto-Slavic with the West Indo-European core – much easier…

calcolithic-expansion
Chalcolithic expansion from Yamna into Corded Ware (as early North-West Indo-European dialects), as interpreted in the second edition of A Grammar of Modern Indo-European.

Recent papers, when compared to what linguists and archaeologists had been saying for years – before even Y-DNA haplogroup was a thing for any of these now popular genetic labs (not to speak about internet geneticists) -, leave little space for doubt right now. I embraced the results of haplogroup analysis of modern populations, which seemed to support an expansion of Proto-Indo-European R1a-lineages with the Corded Ware culture, and dismissed thus Gimbutas’ and Anthony’s model (of a Yamna -> Bell Beaker expansion of Italo-Celtic). I also embraced the results of the publications on genetics of 2015 with open arms.

But, I was able to change my mind when the careful observation of individual samples of these recent studies began to contradict what we thought, and I did so publicly only recently (publishing the Indo-European demic diffusion model), and more strongly after the latest papers (publishing the updated second edition), without remorse. And I will reverse that decision again if needed, and change it again and again as I feel necessary, no matter how many times. In Science, to adapt to new data does not make you a brownnoser, it makes you a scientist. Not to adapt to new data does not make you a man of firm ideals, or any chivalrous concept you might have about that, it makes you look ignorant and biased. It’s that simple.

Some of you may think that there is a third way: to keep an old, now unlikely idea you have supported in the past, but not bragging about it in the meantime until it is proven fully wrong, just in case it is demonstrated to be right in the end – because then you might claim you were right all along, like you had some magic understanding or hidden data the rest of us didn’t. I don’t think that’s the correct way to behave in a scientific environment, either. That makes you a coward. And you wouldn’t have been right all along: you would have been right, then wrong, then right again. Everybody can see that, and so do you.

Geneticists working on future publications should be planning ahead of what might happen. The overconfidence of Haak et al. (2015), Mathieson et al. (2015), and Allentoft et al. (2015), including Lazaridis et al. (2016), in supporting a Yamna -> Corded Ware migration, and a Corded Ware -> Bell Beaker migration are understandable in a rapidly growing field that didn’t leave enough time to study complex anthropological questions. The recent errors of following that simplistic and wrong model in Mathieson et al. (2017), and Olalde et al. (2017), coupled with Kristiansen’s (2017) and Anthony’s (2017) new interpretations (to fit the conclusions of those genetic studies), can be forgiven, because of all the fuss created around the Steppe admixture concept, and the desire of journals to publish popular papers, and of researchers to go with the tide and gain some popularity along the way.

From now on, however, if the evidence keeps pointing in the same direction, a lack of attention to anthropological detail will be simple wishful ignorance, and that cannot be forgiven in any field that strives to ascertaining the truth. If continued, this trend will damage the field of Human Evolutionary Biology for years – at least in the view of anthropologists, who are the real filter of this field’s conclusions -, when its current results prove wrong. Genetic studies will be banished from anthropological studies, dismissed as a pseudo-science, and avoided by any scientific or academic journal worthy of a minimum self-respect.

To regain trust in a field that purportedly uses “more scientific methods” but is nonetheless proven that wrong for years in its essential assumption (a Yamna -> Corded Ware migration model), and especially when it is associated with the traditionally despised ‘Kossinnian trends‘, will be a hard task for those involved. So many postdoc offers in so many labs being created right now will vanish, as the interest in publishing papers of this discredited field will disappear. This could also threaten the recently renewed impulse by archaeologists and linguists of migration models, which had been rejected for a long time, giving impulse to those who deny them ( e.g. in the UK and in France), or who just don’t want to see Archaeology or Linguistics get involved with such a controversial question, or even between each other.

High-impact factor journals like Nature, Science, PNAS, and those not so famous, as well as their reviewers and readers, are doing a disservice to the endeavour of ascertaining the historical truth, if they allow this to happen without protesting. But such consequences for the field will be their making, and not that of suspicious anthropologists, who do well in distrusting any revolutionary results published by overconfident researchers from newly developed and too broadly defined subfields.

Indo-European and Central Asian admixture in Indian population, dependent on ethnolinguistic and geodemographic divisions

indian-population-genetics

Preprint paper at BioRxiv, Dissecting Population Substructure in India via Correlation Optimization of Genetics and Geodemographics, by Bose et al. (2017), a mixed group from Purdue University and IBM TJ Watson Research Center. A rather simple paper, which is nevertheless interesting in its approach to the known multiple Indian demographic divisions, and in its short reported methods and results.

Abstract:

India represents an intricate tapestry of population substructure shaped by geography, language, culture and social stratification operating in concert. To date, no study has attempted to model and evaluate how these evolutionary forces have interacted to shape the patterns of genetic diversity within India. Geography has been shown to closely correlate with genetic structure in other parts of the world. However, the strict endogamy imposed by the Indian caste system, and the large number of spoken languages add further levels of complexity. We merged all publicly available data from the Indian subcontinent into a data set of 835 individuals across 48,373 SNPs from 84 well-defined groups. Bringing together geography, sociolinguistics and genetics, we developed COGG (Correlation Optimization of Genetics and Geodemographics) in order to build a model that optimally explains the observed population genetic sub-structure. We find that shared language rather than geography or social structure has been the most powerful force in creating paths of gene flow within India. Further investigating the origins of Indian substructure, we create population genetic networks across Eurasia. We observe two major corridors towards mainland India; one through the Northwestern and another through the Northeastern frontier with the Uygur population acting as a bridge across the two routes. Importantly, network, ADMIXTURE analysis and f3 statistics support a far northern path connecting Europe to Siberia and gene flow from Siberia and Mongolia towards Central Asia and India.

Among the most interesting results (emphasis mine):

Our meta-analysis of the ADMIXTURE output shows that the IE and DR populations across castes shared very high ancestry, indicating the autochthonous origin of the caste system in India (Figure 2). f3 statistics show that most of the castes and tribes in India are admixed, with contributions from other castes and/or tribes, across languages affiliations (Supplementary Table 4 and Supplementary Note). The geographically isolated Tibeto-Burman tribes and the Dravidian speaking tribes appear to be the most isolated in India. Linear Discriminant Analysis on the normalized data set clearly supports genetic strati cation by castes and languages in the Indian sub-continent

(…)

Our meta-analysis of the ADMIXTURE plot in Figure 4A quantifies the ADMIXTURE results (darker colors indicate higher pairwise shared ancestry). Indian populations show a greater proportion of shared ancestry with the so-called Indian Northwestern Frontier populations, namely the tribal populations spanning Afghanistan and Pakistan. Central Asian populations share higher degrees of ancestry with IE and DR Froward castes. Uygurs share high degrees of ancestry with Indian populations.

(…)

f3 statistics (all negative Z-scores are shown) indicate Chinese and Siberian ancestry contributing to the Tibeto-Burman tribal speakers. On the other hand, the Mongols and the Europeans have contributed significant amounts of ancestry to the Indo-European and Tibeto-Burman forward castes. F3 statistics also show that the Central Asians are an admixed population with signs of admixture from Caucasus and other parts of Europe.

Among the results for proportions of shared ancestry between Indians and Eurasians (FIG. 4), there is an obvious influence of European admixture (Caucasus, and Southern, Central, and Northern EU), potentially from the Yamna-Corded Ware expansion, in IE_ForwardCaste, which is lessened in IE_BackwardCaste and also in IE_Tribal, while DR_ForwardCaste shows again more admixture than IE_Tribal, but diminishing with lower castes and quite low in DR_Tribal.

Ancestry from Central Asia is strong with a similar pattern, which hints at the influence of Sintashta, Andronovo, and BMAC influence in the expansion of the Steppe component, even more than a later Turkic component.

On the other hand, the influence from Turkey is difficult to assess, given the complex genetic history of Anatolia, but the map contained in Fig. 6 doesn’t feel right, not only from a genetic viewpoint, but also from linguistic and archaeological points of view. This is the typical map created with admixture analyses that is wrong because of not taking into account anthropological theories.

Quite interesting is then the influence of admixture in these different ethnolinguistic groups, Indo-European and Dravidic, which points to an initially greater expansion of Indo-European speakers, and later resurge of Dravidian languages.

The over-simplistic “Kossinian Model”: homogeneous peoples speaking a common language within clearly delimited cultures

proto-greek-mynian-ware

There seems to be a growing trend to over-simplistic assumptions in archaeology and linguistics, led by amateur and professional geneticists alike, due to the recent (only partially deserved) popularity of Human Evolutionary Biology.

These studies are offering ancient DNA samples, whose Y-DNA and mtDNA haplogroups and admixture analyses are showing some new valuable information on ancient cultures and peoples. However, their authors are constantly giving uninformed conclusions.

I have read a good, simple description of the Kossinnian model in the book Balkan Dialogues (Routledge, 2017), which has been shared to be fully read online by co-editor Maria Ivanova.

Chapter 3, The transitions between Neolithic and Early Bronze Age in Greece, and the “Indo-European problem”, by Jean-Paul Demoule, offers a clear account of the difficulties found in tracing the arrival of Proto-Greek speakers to Greece or the “Coming of the Greeks”. The identifications of cultural breaks most commonly supported by academics as potentially signaling the arrival of Proto-Greeks are cited, including the Early Helladic III period ca. 2300 BC (with the diffusion of Mynian ware), or the Middle Helladic period ca. 2000 BC. The problem of finding a clear cultural break before the emergence of Mycenaean Greece (which obviously spoke an early Greek dialect) has led some to adopt a “Palaeolithic autochthonous theory” (Giannopoulos 2012), which offers still more problems than it solves.

Of interest is his reference to Kossina in light of the recent popularity in resorting to DNA to answer all problems. It is mandatory for the field of Indo-European studies – regardless of what renown labs and journals of high impact factor are publishing – to avoid carrying on “in the steps of race based cranial measurement which enjoyed its floruit in the 19th century before fading into oblivion.”

This is why, without denying the relationship between Indo-European languages, we need to question the validity of the overall model itself, which has shown itself to be over-simplistic in assuming the movement of permanent and long-lasting homogeneous “peoples”. More precisely, we have to criticize in details the “Kossinnian Model” underlying all those assumptions – “Kossinnian”, because of the German archaeologist Gustaf Kossina (1858–1931), well known for the famous sentence: “Cultural provinces, which are clearly delimited on the basis of archaeology, correspond in every era to specific peoples or tribes” (“Scharf umgrenzte archäologische Kultur-provinzen decken sich zu allen Zeiten mit ganz bestimmten Völkern und Völkerstämmen”). Four basic assumptions arise from this central idea:

  1. Changes in languages are due to population movements, usually involving conquest, and every migration implies a linguistic change.
  2. Archaeological “cultures” are homogenous ethnic groups, with defined frontiers, based on the model of 19th- and 20th-century nation-states and equally on the model of biological entities that reproduce by parthenogenesis.
  3. There is coincidence between language and material culture.
  4. Finally, languages are also homogenous biological entities which are autonomous and clearly delimited, and which can reproduce by parthenogenesis or by scissiparity.

Unfortunately, none of these points is self-evident and each can be countered by a number of historical examples (Demoule 2014: 553–592).

While I agree with the first part of the first statement attributed to the “Kossinnian model”, i.e. that languages are usually the product of population movements (either involving conquest or not), the other statements are obviously and demonstrably false, and are frequently assumed in comments, blog posts, forums, and even research articles – particularly in those based on genetic studies -, and this trend seems to be increasing lately.

The Aryan migration debate, the Out of India models, and the modern “indigenous Indo-Aryan” sectarianism

indus-valley-early-harappan

The Proto-Indo-European Urheimat

Not long ago, the Proto-Indo-European language Urheimat problem used to be cyclic in nature: linguistic and archaeological publications appeared supporting a Copper Age migration from the steppe proposed by Marija Gimbutas, or a Neolithic expansion from Anatolia (or Armenia) proposed by Colin Renfrew, and back again.

I have always supported the simpler, more recent Chalcolithic migration of Late Indo-Europeans from the Pontic-Caspian steppe over an older Neolithic expansion from Anatolia with agriculture. The latter model implied a complex cultural diffusion over a greater span of time than is warranted by linguistic guesstimates, understood as the general grasp that anyone can have on how much a language changes in time, comparing the different stages of different Indo-European languages. Whether they like to talk about it or not, or whether they would describe them as such (or else as terminus ante or post quem), most known linguists and archaeologists involved in Indo-European studies have published at some point their own guesstimates.

To have an idea about how guesstimates work, you only have to learn some Indo-European languages from different branches, the ancient languages from which they are derived, how they have evolved from them through time, and their proto-languages, to see how unlikely it is that the differences from Late Indo-European to Proto-Greek, Proto-Indo-Iranian, Proto-Celtic, or Proto-Italic need a leap of ca. 3000 years almost without change, as required by the Anatolian hypothesis. Some have strong reactions against guesstimates arguing you cannot compare historic or proto-historic changes to prehistoric ones, to support a different linguistic change rate from Proto-Indo-European to proto-languages. I find this to be a sound criticism, but often used justify a worse, ad-hoc estimate that supports other theory.

Glottochronology – in case you are looking for mathematics or statistics to solve the problem – is as useless today as it always was. Not everything – in fact few things in anthropology – can be solved with algorithms and statistics. I do love algorithms and statistics, because their results – if based on sound assumptions – are hard to be contested, but not a single good one has been proposed for comparative grammar, as far as I know.

Algorithms solve everything

Steppe hypothesis

The steppe hypothesis was always the simpler connection with modern Indo-European languages, from a linguistic and archaeological point of view, and archaeogenetics (since the advent of haplogroup investigation, and the finding of modern R1a distribution) did also support it. However, it implied a conquest by warring patrilocal peoples, that substituted the ‘original’ Neolithic European and Asian population and languages, and invasions have not been a fashionable antrhopological subject for a long time.

One of the consequences of the genocidal racism and xenophobia seen during World War II was the strong reaction to its ideological foundations, and there was a common will to end with Kosinna’s trend of historic ethnolinguistic identification of modern peoples. Linguistics and archaeology did then search for more complex models of human relations and exchange, mostly to avoid what appeared as simplistic concepts of migration or invasion. Marija Gimbutas’ simplistic kurganist, male-driven invasion of territories inhabited by matrilocal Old Europeans, albeit reasonable, did not fit well with these post-war times. One could accept historic and proto-historic atrocities and genocide by any people against others, and even tribal conflicts between prehistoric hunter-gatherers that ended in the destruction of one of them, but a violent, massive spread of ‘Aryans’ was considered a dangerous idea to be avoided.

Thanks to the effort of David Anthony (among others) in supporting migration models in Archaeology, the steppe model did have a strong revival even before archaeogenetics began to be a thing in anthropological research.

Anatolian hypothesis

The Anatolian hypothesis, on the other hand, seemed like a fine, long evolution of a language accompanying the peaceful spread of a technological innovation, farming and cattle herding. Originally believed to be mostly a cultural diffusion (now it has been demonstrated to be a mixed diffusion event, with strong demic diffusion in its early phase), it was thus in line with a more politically correct view of prehistoric events.

This cultural diffusion gave in turn way to more peaceful and innovative solutions to language spread, like waves of expansion, or a constellation of languages influencing each other for long periods, so that even the potential reconstruction of a single Proto-Indo-European language or people was doubted. Prehistoric friendly neighbours would have adopted farming and exchanged goods and languages for thousands of years, and only with proto-historic events did people have ethnolinguistic identification that caused conflicts…

While recently there have been some doubts expressed by Mathieson et al. (2017) on the of the steppe hypothesis regarding Proto-Anatolian, it is likely that the lack of enough ancient DNA of the Balkans and Anatolia is the key factor here.

An interesting linguistic proposal, the glottalic theory, while sound in its assumptions and results – much less likely in my opinion than the more common two-dorsal theory, and this much more likely than the prevalent three-dorsal one – gave some theoretical support to the Anatolian (or Armenian) hypothesis, since some proponents felt that a glottalic Proto-Indo-European should have an origin near to the Armenian homeland – because glottalic Proto-Armenian would have retained a phonetic state nearer to the “original” Proto-Indo-European.

That simplistic regional continuity explanation is akin to the trend of Basque researchers to discover links of Proto-Basque with the Pyrenees in Mesolithic and Palaeolithic times, when there is no data to warrant such identifications – and it seems in fact that Proto-Basque, Proto-Iberian, and Palaeo-Sardinian might have accompanied the expansion of farming in the Neolithic. Probably most proponents left of the Glottalic theory today (like Frederik Kortlandt and Alan Bomhard) would accept a steppe migration unrelated to an Armenian or Anatolian origin.

Marginal proposals

There were indeed other marginal proposals, with people supporting origins of Proto-Indo-European in both ends of the current distribution of Indo-European languages, from the “Indo-” in Out of India theories, to the “-European” in Eurocentric proposals. Most Eurocentric proposals – based on certain archaeological cultures and their evolution in- and outside Europe – have been dismissed with archaeological and genetic research, and the remaining ones usually favour the more fashionable peaceful spread of languages.

Palaeolithic Continuity Theory

A small group in support of the more recent Palaeolithic Continuity Theory remains. It seems to me as deeply flawed from a linguistic point of view (with a much larger time span needed than for a Neolithic expansion), but their arguments are led by research on genetics and archaeology, and not much is left for European romanticism, so it has always appeared to me as a professionally acceptable – although futile – attempt by eccentric researchers to disentangle prehistoric events.

Similar to what happens with proponents of the Anatolian hypothesis, new linguistic, archaeological, and genetic research is used to remake PCT models – instead of just dismissing it -, so it is likely that we will have many different proposals of stepped population movements that will make both models eventually converge with the steppe migration theory, to the point where only the steppe migration theory remains, with some added details on its most ancient origin. I guess sometimes it is difficult to let (part of) your life’s research just go away without fighting for some recognition… You desperately look for a tap on the back by some colleagues, even out of pity, who will tell you ‘it seems you might have been right in some details, after all!’…

Out of India

The Out of India theory is the name given to a group of (mostly) independent models that usually propose a Proto-Indo-European homeland based on or around India. Contrary to the PCT, an Out of India theory set during the Mesolithic or Neolithic would be feasible from a linguistic point of view: you could somehow connect some archaeological migrations to support the spread of Early-Proto-Indo-European-speaking R1a lineage happen east-to-west (and north), and genetically it had support in some papers on modern distribution of R1a subclades, for example in Underhill et al. (2014). Underhill himself has since questioned his conclusion in view of recent papers publishing ancient DNA analysis.

Out of India theories, overall, could thus be as strong (or as weak) as the theories concerning an Anatolian origin, in their potential for explanation of the ancient origin of the Proto-Indo-European language spoken in the steppe during the Neolithic and Chalcolithic. However feasible they might a priori be, I have yet to encounter a decent modern paper with that kind of proposal, based on recent genetic papers. Most modern articles are just Indian nationalist crap, and the only decent papers on this matter are becoming quite old fpr this relatively young field of Indo-European studies. Maybe that’s because I don’t have enough time to look for the hidden good anthropological papers among so much dirt. After all, it is not a very likely theory, and one has a limited amount of time.

In recent papers, if you get rid of simplistic reactionary and revisionist views, conservative Indo-Aryan Hindu nationalist or religious bigotry, fantastic connections with the Indus Valley civilization, and simplistic identifications of Proto-Indo-European as ‘nearer’ to Vedic Sanskrit – with absurdly old and odd references to Schleicher’s reconstruction and dialectal Indo-Slavonic or Satem references -, you are left at best with some basic criticisms of Eurocentrism and the known shortcomings of anthropological disciplines in investigating Proto-Indo-European Urheimat, but no data to support any connection with India whatsoever.

If there is a reason for a generalised inferiority complex in India, I would find it in the shameless publication and popularity of such worthless research papers, a trend that is also seen in scientific fields, with Indian researchers having a increasingly tougher time passing editorial and peer reviews, and resorting thus to national journals. In the case of Indo-European studies, instead of trying to fit data with what we know, the only aim in Indian research seems to be to connect the Indus Valley with Proto-Indo-European, and Proto-Indo-European with a “pure” (i.e. Vedic) Indo-Aryan, to support a mythological Indo-Aryan Hinduist India. And that is mostly what you will find in any Out of India article today, whether based on linguistic, archaeological, or – what is prevalent today – genetic investigation.

This has been The Out of India Controversy Week: it began last week with the publication of a quite decent article in The Hindu by Tony Joseph summing up the current situation of anthropological research. It was followed by reactions in conservative Indian news, and this in turn was contested by Davidsky and Razib Khan. The original article by Tony Joseph has been echoed by Victor Mair in Language Log, and I agree with his description of Joseph’s paper as “informed, sensitive, balanced, and nuanced. This is responsible science journalism”, even if I disagree with some of his statements (in a different way than Mr. Mair). However, this propaganda disguised as scientific criticism is what you get from Indian nationalists.

EDIT (25/6/2017): Razib Khan has published a thorough post on Indian evolutionary genetics as follow-up to this week’s controversy. I think there is too much effort being invested during these controversies precisely by the people who need not explain themselves. Anyway, good summaries of anthropological matters are always welcome.

EDIT (29/6/2017): Other posts on the subject, from Brown Pundits: On the “Aryan” debate – the linguistics POV; Razib Khan’s Indian genetics, part n of many; and Aryan Migration and its Discontents.

Interestingly, any time new research comes to shake certain Indian nationalist foundations, a stronger backfire effect happens, and more criticism is done on the shortcomings of such anthropological research. Because, indeed, if the anthropological theory is flawed, mythical Indo-Aryans spread from the Indus Valley, right…? One can only expect this kind of controversies to escalate in conservative Indian blogs and fora alike, and then deescalate until the next paper is published. A dialectic cycle whose only evident result is the increased opposition that conservative Indian researchers – or researchers that depend on funding by such groups – will have in publishing anything related to a potential Aryan invasion, and the addition of a stronger bias in Indian research.

Western European history

It might well be because I am western European, and western Europeans tend to accept quite well multiple invasions from the East. After all, they have happened so many times in proto-historical and historical times, that it is part of our ethnolinguistic nation-building lore. French people trace their history to the expansion of Celts, Romans, and Franks; Spaniards and Portuguese trace it to the spread of Celts, Ibero-Basques, Romans, and Westgoths; Italians to the expansion of Etruscans, Celts and Italics, Romans, Ostrogoths and Langobards; the English to the expansion of Celts, Angles and Saxons, Vikings, and Normans…

It often seems to me that western Europeans will romanticise their origins no matter what appears in historic and genetic investigation: if Neanderthals are unrelated to Europeans, they are ‘cavemen’; if they intermixed with our ancestors, then they suddenly become quite human in their behaviour, and it is great to have more Neanderthal admixture. If Indo-European-speaking R1a lineages invaded central Europe from the east, and transferred their languages, great, because “we” are heirs of original western European hunter-gatherers of Palaeolithic R1b lineages; if R1b lineages represent an invasion of eastern peoples speaking Late Indo-European, great too, because it means that our paternal forefathers were the ‘original’ Indo-European speakers…

This reaction, our history is great no matter what, seems to be a good one for research, since it allows for any change in our romantic views of the past. This, however, does not seem to be the case for some nations, and this inability to change their views is likely related to the inferiority complex that some nations have developed, in turn probably caused by western European colonialism, so one is left to wonder how responsible we are of modern chauvinist trends.

The sad future

Seeing how so many people of eastern European ancestry are convinced of an origin of R1a-M417 in Indo-European migrations from Yamna – when there is (yet?) not a single proof of it – may be just as troubling as the Indian case, or maybe more, since it affects an important part of Europe. I cannot believe that even today only western Europeans are capable of romanticising their own past no matter what, while the rest of the world lives in a quest to appropriate whatever they view as some great ancient culture, people, or language for their own ancestors.

I have already received complaints and have seen people (of Y-DNA haplogroup R1a) complain online that their forefathers cannot have been Uralic speakers, and some Uralic speakers (of haplogroup N) that original Uralic speakers cannot have been of R1a lineages. Firstly, if I were eastern European – be it Germanic, Balto-Slavic, or Uralic speaker, or a speaker of Indo-Aryan languages, of R1a or N lineage, whatever my country of origin, I like to think I would prefer to know where my forefathers actually came from, and what languages they did in fact speak thousands of years ago, even if that disrupts everything I or my fellow countrymen (wrongly) assumed for a long time. Secondly, we – as western Europeans speaking Romance or Germanic languages – have the right to know exactly how our peoples and languages really came to be, even if that means disrupting others’ dreams. Our paternal ancestors probably changed languages 3 or 4 times during their multiple migrations from the east, and were not peaceful hunter-gatherers living since the Palaeolithic in the same region we do now, as traditionally held; if we can get over this, eastern Europeans and Indians can get over it, too.

I think everyone deserves to know the truth, and they will eventually like it and fantasise with it. But many individuals want to disrupt any possible change to keep their current ethnic and nationalist agendas untouched, and that can affect us all. Nationalistic and romantic trends are understandable: Romans needed Virgil at the peak of their conquests to tell them that they had a glorious past in Troy, connecting them to the immortal Greek epics. The most important lesson one can learn from that example is that Italian researchers are still (2000 years later!) influenced by that myth, and they keep trying to look for Anatolian remains in Latin studies, and in the archaeology and evolutionary genetics of Italy. I guess you could therefore say these mythification trends are naturally human…but losing so much time in absurd quests for mythological identities seems absurd, and can only damage research.

It is sad to think about future generations of Indians looking for any sign to support an autochthonous Indo-Aryan homeland, while the rest of the world keeps moving in the right direction…

Wiik’s theory about the spread of Uralic into east and central Europe, and the Uralic substrate in Germanic and Balto-Slavic

vasconic-uralic

I recently wrote about how Wiik’s model was wrong in supporting a Mesolithic European Vasconic-Uralic harmony – genetically based on the modern distribution of R1b vs. N1c haplogroups -, and thus also the disruption of this harmony by Indo-Europeans (supposedly a population of R1a-lineages invading central Europe from a Balkan homeland).

Romanticism does this quite frequently: it makes us believe in some esoteric fantasy, like the ethnic continuity of our ancestors in the region we live (and a far, far greater original territory that has been unfairly diminished by invaders), providing us with strong links to support our artificial borders and their potential expansion.

Even though my article on the demic diffusion of Indo-European languages does only slightly comment on the origins (and potential language) of N1c-lineages and of Proto-Basque and Proto-Uralic languages, I have already received some angry emails by Basque and Finnish genetic amateurs. I don’t get the point of fantasizing on one’s own ethnicity and prehistoric territory, and then getting through the five stages of grief when one is confronted with different (usually sounder) theories, time and time again. It seems like a lot of time lost by generations in wholly stupid quests and self-negotiation.

However wrong Wiik’s basic theses are, though, if you have read my paper you have seen that Corded Ware groups spread from north-western Ukraine might have spoken Uralic languages. Therefore, it is reasonable to assume that Pre-Germanic, Pre-Balto-Slavic and Pre-Indo-Iranian might have been adopted by peoples who spoke Uralic languages, probably related with each other, possibly belonging to early Finno-Ugric dialects. In that sense, Wiik’s work has a renewed linguistic interest, regarding the potential substrate words he investigated.

This is not a picture that certain Basque, Finnish, Russian, or Indian romantics would have hoped (or even hope today) for, in terms of ethnic, linguistic, and territorial identification, but that is not a real problem, anyway, just another building of imaginary origins that will fall as many others before them. In the same sense, Germanic ethnogenesis has become more complicated than what some would have wanted, with at least three main paternal lineages with completely different ethnolinguistic origins developing together since ca. 2500 BC to form a more homogeneous community only during the Bronze Age. Therefore, no homogeneous exclusive ethnic ‘original’ European regional community can be fantastically invented anymore.

This seems to me a real coup de grâce to genetic-based nationalism in Europe, and it is encouraging for the European Union that Germany, as the central European country, is not only a central territory, but also a central cultural and genetic bridge between west and east Europe, in terms of history, of North-West Indo-European languages, and paternal lineages and admixture analyses.
