Happy new year 2019…and enjoy our new books!

song-sheep-horses-header

Sorry for the last weeks of silence, I have been rather busy lately. I am having more projects going on, and (because of that) I also wanted to finish a project I have been working on for many months already.

I have therefore decided to publish a provisional version of the text, in the hope that it will be useful in the following months, when I won’t be able to update it as often as I would like to:

EDIT (20 JAN 2019): For those of you who are more comfortable reading in your native language, I have placed some links to automatic translations by Google Translate. They might work especially well for the texts of A Game of Clans & A Clash of Chiefs.

Don’t forget to check out the maps included in the supplementary materials: I have added Y-DNA, mtDNA, and ADMIXTURE data using GIS software. The PCA graphics are also important to follow the main text.

NOTE. Right now the files are only in my server. I will try to upload them to Academia.edu and Research Gate when I have time, I have uploaded them to Academia.edu and ResearchGate, in case the websites are too slow.

I would have preferred to wait for a thorough revision of the section on archaeology and the linguistic sections on Uralic, but I doubt I will have time when the reviews come, so it was either now or maybe next December…

I say so in the introduction, but it is evident that certain aspects of the book are tentative to say the least: the farther back we go from Late Proto-Indo-European, the less clear are many aspects. Also, linguistically I am not convinced about Eurasiatic or Nostratic, although they do have a certain interest when we try to offer a comprehensive view of the past, including ethnolinguistic identities.

I cannot be an expert in everything, and these books cover a lot. I am bound to publish many corrections as new information appears and more reviews are sent. For example, just days ago (before SNP calls of Wang et al. 2018 were published) some paragraphs implied that AME might have expanded Nostratic from the Middle East. Now it does not seem so, and I changed them just before uploading the text. That’s how tentative certain routes are, and how much all of this may change. And that only if we accept a Nostratic phylum…

NOTE. Since the first book I wrote was the linguistic one, and I have spent the last months updating the archaeology + genetics part, now many of you will probably understand 1) why I am so convinced about certain language relationships and 2) how I used many posts to clarify certain ideas and receive comments. Many posts offer probably a good timeline of what I worked with, and when.

Edit (23 Jan 2019):

To be able to revise and update the text properly, I decided to start a series of posts on different aspects.

This is an updated list of the posts:

Acknowledgements

I did not add this section to the books, because they are still not ready for print, but I think this is due somewhere now. It is impossible to reference all who have directly or indirectly contributed to this, so this is a list of those I feel have played an important role.

I am indebted to the following people (which does not mean that they share my views, obviously):

First and foremost, to Fernando López-Menchero, for having the patience to review with detail many parts on Indo-European linguistics, knowing that I won’t accept many of his comments anyway. The additional information he offers is invaluable, but I didn’t want to turn this into a huge linguistic encyclopaedia with unending discussions of tiny details of each reconstructed word. I think it is already too big as it is.

I would not have thought about doing this if it were not for the interest of Wekwos (Xavier Delamarre) in publishing a full book about the Indo-European demic diffusion model (in the second half of 2017, I think). It was them who suggested that I extended the content, when all I had done until then was write an essay and draw some maps in my free time between depositing the PhD thesis and defending it.

Sadly, as much as I would like to publish a book with a professional publisher, I don’t think ancient DNA lends itself for the traditional format, so my requests (mainly to have free licenses and being able to review the text at will, as new genetic papers are published) were logically not acceptable. Also, the main aim of all volumes, especially the linguistic one, is the teaching of essentials of Late Proto-Indo-European and related languages, and this objective would be thwarted by selling each volume for $50-70 and only in printed format. I prefer a wider distribution.

At first I didn’t think much of this proposal, because I do not benefit from this kind of publications in my scientific field, but with time my interest in writing a whole, comprehensive book on the subject grew to the point where it was already an ongoing project, probably by the start of 2018.

I would not have been in contact with Wekwos if it were not for user Camulogène Rix at Anthrogenica, so thanks for that and for the interest in this work.

I would not have thought of writing this either if not for the spontaneous support (with an unexpected phone call!) of a professor of the Complutense University of Madrid, Ángel Gómez Moreno, who is interested in this subject – as is his wife, a professor of Classics more closely associated to Indo-European studies, and who helped me with a search for Indo-Europeanists.

EDIT (1 JAN 2019): I remembered that Karin Bojs sent me her book after reading the demic diffusion model. I may have also thought about writing a whole book back then, but mid-2017 is probably too early for the project.

Professor Kortlandt is still to review the text, but he contributed to both previous essays in some very interesting ways, so I hope he can help me improve the parts on Uralic, and maybe alternative accounts of expansion for Balto-Slavic, depending on the time depth that he would consider warranted according to the Temematic hypothesis.

The maps are evidently (for those who are interested in genetics) in part the result of the effort of the late Jean Manco: As you can see from the maps including Y-DNA and mtDNA samples, I have benefitted from her way of organising data and publishing it. Similarly, the work of Iain McDonald in assessing the potential migration routes of R1b and R1a in Europe with the help of detailed maps was behind my idea for the first maps, and consequently behind these, too.

I should thank all people responsible for the release of free datasets to work with, including the Reich and Jena labs, the Veeramah Lab, and also researchers from the Max Planck Institute or the Mainz Palaeogenetics group, who didn’t mind to share with me datasets to work with.

Readers of this blog with interesting comments have also been essential for the improvement of the texts. You can probably see some of your many contributions there. I may not answer many comments, because I am always busy (and sometimes I just don’t have anything interesting to say), but I try to read all of them.

EDIT (1 JAN 2019) I think I should mention at least Chetan, Egg, or Robert George; but then I would leave out old europe, Sgr Ganesh, or Tileman Ehlen; and if I include them I would leave out others…

Users of other sites, like Anthrogenica, whose particular points of view and deep knowledge of some very specific aspects are sometimes very useful. In particular, user Anglesqueville helped me to fix some issues with the merging of datasets to obtain the PCAs and ADMIXTURE, and prepared some individual samples to merge them.

Even without posting anything, Google Analytics keeps sending me messages about increasing user fidelity (returning users), and stats haven’t really changed (which probably means more people are reading old posts), so thank you for that.

I hope you enjoy the books.

Happy new year!

The Lower Danube during the Eneolithic, and the potential Proto-Anatolian community

zhivotilovka-type-burials

Local cultural settings and transregional phenomena: on the impact of a funerary ritual in the Lower Danube in the 4th millennium BC, by Frinculeasa & Mirea, In: Buletinul Muzeului Judetean Teleorman, Seria Arheologie, 9, 2017, p. 75-116.

Interesting excerpts (emphasis mine):

1. In the area under discussion, around 4300-4200 BC – a chronological segment marking the evolutionary peak of ‘Old Europe’ (Anthony 2007: 225), represented by the Cucuteni A/ Tripolie BI, Aldeni-Bolgrad, Gumelniţa-Karanovo VI cultures – the first tumular burials appeared (Govedarica 2016: 85). However, flat burials, marked by the existence of some allogeneous elements in the local Eneolithic milieu, were also present. These finds have been linked to the presence (in terms of both trade and conflicts) of Suvorovo/Suvorovo-Novodanilovka communities (Anthony 2007: 251ff.; Govedarica and Manzura 2011: 46ff.; Reingruber and Rassamakin 2016) or of some groups from the ‘western part of the Skelia culture’ (Anthony 2007: 251ff.; Govedarica and Manzura 2011: 46ff.; Reingruber and Rassamakin 2016). (…) The zoomorphic sceptres and the four-knobbed stone mace heads found east of the Prut/the Lower Danube are also related to this topic (Govedarica 2004; Govedarica and Manzura 2011: abb. 5; Gogâltan 2013).

2. The next chronological segment intersects the ‘hiatus’ recorded between the end of the Gumelniţa-Karanovo VI cultural complex and the beginning of the Cernavoda I culture (Rassamakin 2011a: 85ff.; Govedarica and Manzura 2011: 51). We should also mention the existence of a small set of absolute dates ranging within the interval 4200/ 4150 – 3900/ 3850 BC that come from the sites of Sultana, Vităneşti, Pietrele, Bucşani, Ploieşti ‘Triaj’, Ovcarovo, Hotnica etc. (Reingruber 2015; Reingruber and Rassamakin 2016; Frînculeasa 2016; Bem and Haită 2016: 63; Krause et al. 2016). The examples of Sărăteni and Krasnoe15 and the abovementioned dates seem to fill out a part of this chronological segment. It is still difficult to say whether they reflect the presence of some communities that led to the disappearance of the Gumelniţa-Karanovo VI complex or are connected with an early Cernavoda I, or possibly late Suvorovo evolution. If we refer to the absolute dates obtained for samples taken from mammal bones found in Cernavoda I settlements, we notice that the appearance of this culture in the abovementioned chronological interval is not yet confirmed (Frînculeasa 2016, tab. 3).

3. The Cernavoda I discoveries (approximately 3850/3800 – 3550/3500 BC) are represented in the Lower Danube by settlements and flat graves (the presence of tumular burials should not be completely excluded, see Brăiliţa). In the Bugeac area, the Cernavoda I culture was until recently defined only by tumular burials (Manzura 1999). The presence at Orlovka of flat graves and of a settlement (with two habitation levels, in which the Cucuteni B painted pottery occurs in association with the unpainted pottery with crushed shells into the paste) (Govedarica and Manzura 2015; Manzura 2018) shows that we are dealing with the same cultural phenomenon both west and east of the Prut, beyond the so-called ‘Bessarabian version’. North of the Danube there are flat burials, with individuals in side-crouched position. Unlike the tumular graves (including the early ones), in the flat graves there are no ornaments, only (unpainted) pottery items, including at Orlovka cemetery.

kvityana-cernavoda
Map of funerary finds with skeletons in extended position from the 4th millennium BC and
contemporaneous cultural areas.

Therefore, the presence of tumular graves east of the Prut, in the same chronological interval, may be related to phenomena located east of the Dniester. In fact, Y. Rassamakin associates these finds with the Lower Mikhailovka culture, which precedes here the ritual that is specific to Kvityana communities (Rassamakin 1994: 42, 44; 1999: 92). He establishes a chronological relation between a number of findings such as the plastic anthropomorphic representations from Cernavoda, Râmnicelu, Târpeşti, Folteşti and Satu Nou (Neagu et al. 1982) and Dereivka (Rassamakin 1994: 41; 1999: 90), which seems to point to a revival of contacts between the North Pontic area and the Lower Danube, contacts which had been interrupted with the dissolution of the Gumelniţa-Karanovo VI cultural complex (Reingruber and Rassamakin 2016).

4. At the middle of the 4th millennium BC (we do not exclude that it could reach the end of the chronological interval in which the Cernavoda I culture evolves), we can establish the occurrence (in secondary position) in tumuli – located in the Prut-Dniester interfluve – of graves with deceased laid in extended position. It is a period in which the Kvityana funeral traditions transcend their place of origin. The painted pottery culture provides evidence for, indirectly or directly through the presence of vessels in graves, including east of the Dniester (Rassamakin 2011b; 2013a), the contact and the chronological relationship. Placing the constructions with rings later towards the last third of the 4th millennium BC is supported by the Usatovo finds (Tripolie CII) which are posterior to the Cernavoda I ones (Govedarica and Manzura 2011). The relationship and direct chronological relation between the Kvityana and the (early) Usatovo is also supported by the discovery of Sadovoe (Maljukevich and Petrenko 1993: fig. 5/2). (…)

5. Another horizon with burials of individuals in supine position is stratigraphically recorded between Zhivotilovka and Yamnaya (the last third of the 4th millennium BC); however, a coexistence of both cultural/ funerary groups with specific ritual elements (side-crouched and supinely with knees folded and raised) is not excluded either. The absence of inventory and of ochre and the presence of oval-elongated pits are specific elements.

6. (…) The extended position disappeared in the Early Bronze Age/ 3rd millennium BC (Rassamakin 2013a: 116), but is to be found again in the Katacombnaya ritual (Frînculeasa et al. 2017a). Ascertaining the many discrepancies regarding the contexts and radiocarbon dates, we maintain our reservations on this matter as well. Therefore, the two samples do not represent a solid basis for a possible discussion

From the conclusions:

If the Kvityana evolution covers a significant part of the first half of the 4th millennium BC, and partially the second half, west of the Prut we are dealing with Cernavoda I and later Usatovo communities in the same chronological time frame. The relationship between this ritual/ Kvityana and the Cernavoda I culture, which is stratigraphically unclear, and the absence of items to prove direct contacts show a slight chronological gap in favour of the Cernavoda I culture and the side-crouched ritual, at least in the Prut-Dniester interfluve. This ritual continues to be present, crosses the evolution of Zhivotilovka communities and continues as far as the start of the Yamnaya. The extended position is a late occurrence within the tumular burials in the Lower Danube, but here it is also a rather discreet ritual, one that seems to be of secondary importance. The presence of this ritual (and the accurate interpretation of stratigraphic situations) is an additional element for establishing a better chronological and chorological relationship between the West Pontic area and realities located in the North Pontic steppe, amidst a phenomenon which seems to have rewritten history in other parameters, initially of the Lower Danube and then of Western Europe.

If someone was still relying on Gimbutas – and mostly anything before the 2000s, like “kurgans”, in general terms – to assess cultural developments, and particularly ethnolinguistic identifications, it is time to let it go. The situation in the North Pontic area reveals itself far more complex with each new assessment of recent findings and radiocarbon dates.

By now it is evident that the LPIE-speaking community, formed in the Khvalynsk/Repin -> Yamna period, became dominated by R1b-M269 subclades early during its formation and expansion, based on what we have already seen in the Afanasevo expansion to the east, in the Bell Beaker migrants to the west, and in the admixed lineages (with incoming Abashevo peoples) in the North Caspian steppe that formed the Early Indo-Iranian community. While we don’t have much data on the Balkan region, especially Yamna migrants leading to the Proto-Greek migration, it is quite likely to support this, too.

Therefore, earlier PIE stages are the most likely objects of controversy for the future. Just like proponents of the Anatolian and Armenian homeland theories have surreptitiously shifted their proposal of “farmers expanding LPIE languages” to “farmers expanding earlier PIE stages”, we will see many different accounts of how late Khvalynsk/Repin came to be, and especially of what new culture now represents Middle PIE, be it early Sredni Stog, Northern Iran, or the Lower Danube.

I am not a priori radically opposed to any of those territories as potential earlier ‘original’ (i.e. Early PIE) homelands, although none of them is a likely Middle PIE Urheimat. The fact that such renewed proposals seem to be mostly based on haplogroups or ancestral components mixed into newly formed pet theories, instead of sound linguistic and archaeological models of cultural continuity (following late Khvalynsk/Repin backwards to their most likely forming cultures) does not help their cause.

neolithic_steppe-anatolian-migrations
Most likely Pre-Proto-Anatolian migration with Suvorovo-Novodanilovka chiefs in the North Pontic steppe and the Balkans.

I am certainly not opposed to a strong influence on the formation of a Middle PIE-speaking community (in terms of Y-DNA lineages and potentially language, since genomics cannot change our knowledge of prehistoric cultures) due to immigrants from the Caucasus. After all:

  1. There seems to be a Northern Caucasian (phonetic) substrate in Middle PIE compared to Uralic;
  2. There is an obvious genetic contribution to both North Pontic and North Caspian steppe communities (probably greater in the latter); and
  3. If you defend an Indo-Uralic community – e.g. in a Neolithic steppe cultural-historical community, as I would be inclined to support – , a sizeable migration from the south – whether driven by female exogamy, male migrants, or both – would explain that influence.

Nevertheless, even in this case of an obvious migration (e.g. by R1b-M269 lineages) from the Caucasus, we could be talking about a Caucasian group influencing the formation of a Middle PIE community, represented by Khvalynsk, i.e. not necessarily about a Maykop-Khvalynsk community.

That is, peoples from the Caucasus could have admixed with the (already diverse) North Caspian steppe community to form the Middle PIE-speaking peoples whose expansion developed both known dialectal splits:

  1. Proto-Anatolian, probably represented by Suvorovo-Novodanilovka chiefs, but possibly by Maykop; and
  2. Late PIE, undoubtedly represented by the community forming in late Khvalynsk/Repin -> Yamna.

The Lower Danube remains thus the most important region to investigate, looking for traces of a Proto-Anatolian migration out of the steppe. Today this route seems more likely than Gimbutas’ original idea of Maykop representing a steppe offshoot, since the culture and thus its contacts with the steppe are older than she expected, Anatolian is dated earlier than she could have known based on the works available then, and even the latest available language guesstimates and radiocarbon dates don’t fit quite right in light of the known cultural contacts.

Until some proof appears of a different origin than what archaeologists have described to date, we need more than a simple one-paragraph informal pet theory to change the mainstream model.

A) Given that data from Mesolithic and Eneolithic Pontic-Caspian steppe shows a mixed population in terms of haplogroups, and R1b-M269 lineages are still nowhere to be seen – in the three samples from the Samara region of the Khvalynsk culture -, I can still only guess that it is precisely the expansion of Middle PIE (Pre-Proto-Anatolian and Pre-LPIE) the event associated with the expansion of chiefs of R1b-M269 lineages, especially R1b-L23 subclades, and the general reduction in haplogroup variability, as is obviously seen later in Yamna.

B) If this haplogroup is found first in the Caucasus, and then in Maykop and Khvalynsk during and after their known contacts, though, instead of in Suvorovo-Novodanilovka chiefs, then the question may be settled as Reich recently proposed, and we may have to revise the language split (or, rather, the loss of contact between both MPIE dialects) to a slightly later date.

C) As a third, more complex alternative, if such haplogroup reduction actually happened slightly later – which is unlikely based on modern R1b-M269* and R1b-L23* haplogroup distribution – , say during the expansion of Khvalynsk and Repin as a Yamna community, then

C.1.) any lineage up to that point with steppe ancestry (including the R1b-V88 sample found in Varna, the same lineage apparently found in a likely early chief from Samara) could be the smoking gun of a potential Proto-Anatolian community spreading through the Balkans.

C.2) Alternatively, if it’s the Caucasus or Northern Iran the origin of Middle PIE formation, then any haplogroup or admixture from Maykop to Anatolia could represent Proto-Anatolians…

We just need more samples near the steppe in time and space to depict a clearer genetic image.

EDIT 28-29 APR 2018: Changes made to the text, including the possibility of a Maykop route.

Y-DNA haplogroup R1b-Z2103 in Proto-Indo-Iranians?

chalcolithic_early-asia

We already know that the Sintashta -> Andronovo migrants will probably be dominated by Y-DNA R1a-Z93 lineages. However, I doubt it will be the only Y-DNA haplogroup found.

I said in my predictions for this year that there could not be much new genetic data to ascertain how Pre-Indo-Iranian survived the invasion, gradual replacement and founder effects that happened in terms of male haplogroups after the arrival of late Corded Ware migrants, and that we should probably have to rely on anthropological explanations for language continuity despite genetic replacement, as in the Basque case.

Nevertheless, since we have very few samples, I think we could still see a clear genetic contribution from Yamna to Corded Ware immigrants in the North Caspian region (from Abashevo, in turn a mix of Fatyanovo/Balanovo and Catacomb/Poltavka cultures) in terms of:

  • Ancestral components and PCA in new Sintashta-Petrovka, Andronovo, and/or later samples – similar the ‘steppe’ drift seen in Potapovka relative to Sintashta samples, both formed by incoming Corded Ware migrants – ; and
  • R1b-L23 subclades, either appearing scattered during the Sintashta melting pot (of Abashevo/R1a-Z645 and East Yamna-Poltavka/R1b-Z2103 peoples), or resurging after this period, as we have seen in Pre-Balto-Slavic territory.

This contribution could better explain the obvious language continuity in the region, beautifully complementing the complex anthropological model we have now of archaeological continuity of Sintashta and Potapovka with the previous Poltavka, seen in a similar material and symbolic culture that survived the arrival of newcomers.

A lot of people seem to be looking like crazy since O&M 2018 for some sort of connection between Corded Ware and Yamna migrants in Eastern and Central Europe (wheter in SNP calls of samples published, or among almost forgotten academic papers), either to support the ideas of the 2015 papers – for those who relied on their conclusions and built (even if only mentally) far-fetched migration models around it – , or just because of some sort of absurd continuity theory involving modern R1a-Z645 subclades:

NOTE. The situation we have seen with the hundreds of samples from O&M 2018, and with the recent additional Eastern European samples, depict an unexpected absolutely clear-cut distinction in Y-DNA haplogroups between Corded Ware and Yamna/Bell Beaker: I really can’t see how the situation could be more obvious for everyone, so I doubt any further samples will make certain people change their minds. Their hope is, I guess, that just one sample may give some more oxygen to infinite pet theories, as we are still surprisingly seeing even with reactionary R1b autochthonous continuists in Western Europe…

However, looking into the most likely future for the field, what we should be expecting right now is continuity of Yamna ancestry and lineages in early Proto-Indo-Iranian territory. Since we only have a few samples from Sintashta-Petrovka, Potapovka, and Andronovo, I think there might be a sizeable number of R1b-Z2103 subclades in the territory inhabited by those who – no doubt – spread the language into Central Asia.

Haplogroup_R1b_(Y-DNA)
Modern Y-DNA haplogroup R1b distribution, by Maulucioni at Wikipedia

While full population replacement by R1a-Z93 lineages in the North Caspian region ca. 2000 BC is not impossible, I don’t think it is very likely, since we already know that there are R1b-Z2103 lineages widely distributed in Indo-Iranian-speaking territory, and Z93 is now known to be an older subclade than YFull’s mean formation date suggested (due to the Ukraine_Eneolithic I6561 sample‘s SNP call), so what we can infer now that actually happened in Sintashta -> Andronovo is not exactly the spread of haplogroup Z93 during its formation, but rather a regional reduction in its variability coupled with the expansion of some of its subclades.

The main question, after the South Asia paper is finally published, will then be:

  1. Given that Yamna peoples were an elite group of patrilineally-related families mainly of R1b-L23 subclades:
  2. Accepting that PCA, ADMIXTURE, and other statistical methods are not relevant (alone) for ethnolinguistic identification: e.g. Yamna ‘outliers’ and East Bell Beaker migrants of R1b-L23 lineages without steppe ancestry; N1c1a1a-L392 lineages and Siberian ancestry unrelated to Uralic speakers; R1a-Z645 and steppe ancestry in North-East Europe related to Uralic-speaking cultures
  3. If we find now, as I expect, genetic continuity of east Yamna in Sintashta -> Andronovo (relative to other late Corded Ware peoples), probably including haplogroup R1b-Z2103 mixed with R1a-Z93 before its further reduction of subclades (e.g. to L657) and expansion during its subsequent spread southward…

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

Why exactly do we need Corded Ware to explain migrations of Late Indo-European speakers?

In other words: if we had the data we have today in 2015, would we have a need for Corded Ware to explain Indo-European migrations from the steppe? Are some people so blinded by their will to (appear to) be right in their past interpretations that they can’t just let go?

NOTE. On a side note, wouldn’t it be nice for this paper to publish some other R1b-L23 (x2103) sample – maybe even R1b-L51 – in Yamna, Andronovo, or Afanasevo territory, to end both autochthonous continuity theories (of North-Eastern and Western Europe) at the same time?

I really hope someone in David Reich’s team understands this matter, or else they will still identify Corded Ware as the (now probably ‘a’ instead) vector of expansion of Indo-European languages, and some of us will still have fun for another 2 or 3 years with such conclusions, until someone in the lab realizes that ancestry ≠ population ≠ ethnic identification ≠ language.

NOTE. It seems rather dull to read how people are discussing in the Twitterverse conventional constructs like ‘human race‘ as found in Reich’s op-ed in The New York Times, as if such grandiose semantic discussions had any practical meaning, when basic anthropological questions actually relevant for Genomics, like the essential ancestral component ≠ people tenet seem not to be of interest for anyone in the field….

Since our Indo-European demic difusion model (and its consequences for our reconstruction of North-West Indo-European) and this blog are becoming more and more popular each day – judging by the constant growth in visits in the past 6 months or so – , I guess the simplemindedness and predictability of certain geneticists is benefitting traditional anthropology directly, driving more and more amateur geneticists to look for sound academic models to answer the growing inconsistencies of genetic research.

NOTE. I am not saying the rejection of Corded Ware as spreading Indo-European is definitive. Maybe more samples within some years will depict a clear ancient expansion of Early or Middle Proto-Indo-Europeans from Khvalynsk to the forest-steppe and forest zone, and later with certain Corded Ware migrants into Central Europe, over whose territory a Late Indo-European dialect from Bell Beakers became the superstrate, as some have proposed in the past – e.g. to explain Krahe’s Old European hydronymy. I really doubt you could demonstrate such an old ethnolinguistic identification with a clear, unbroken archaeological trail, though, and we know now that this old hydronymy is probably of Late Indo-European nature (possibly even more recent).

What I am saying is: with the data we have now, it does not make any sense to keep the anthropological models invented by geneticists ex nihilo in 2015, and the hundred different alternative Late Indo-European migration models that arebornwitheachnewpaper.

These Yamna -> Corded Ware migration models didn’t have any sense for me since early 2016, but now after O&M 2017, and especially O&M 2018, I don’t think any geneticist with a little knowledge in Linguistics or Archaeology (if they are decent about their quest for truth in describing ancient European migrations) would buy them, if not for some sort of created ‘tradition’. So let’s ditch Corded Ware as Late Indo-European-speaking, let’s accept that late Corded Ware migrants should most likely be identified as early Uralic speakers, and then future data will tell if we are – again – wrong.

Please, don’t let Genomics become another pseudoscience based solely on Bioinformatics like glottochronology: let anthropologists (preferably mainstream archaeologists, but also the true Indo-Europeanists, linguists) help you interpret your raw data. Don’t deceive yourselves thinking that you have read enough about the Indo-European question, or that you know enough Indo-Europeanists (say what?) to derive your own conclusions.

Use the South Asia paper to begin expressly retracting the Corded Ware mess.

Please pretty please with sugar on top?

For commenters: this post concerns an anthropological question, and deals with the expansion of Late Proto-Indo-European speakers from Yamna, and the controversy surrounding the role of Corded Ware migrants that a handful of academics propose spread from it, based on a renewed model of Gimbutas’ outdated Kurgan theory and on the so-called ‘Yamnaya’ ancestry.

It happens so that the discussion has turned lately mainly to ancient Y-DNA haplogroups, because they help confirm previous mainstream anthropological models of cultural diffusion and migration. It is obviously not reasonable to judge prehistoric ethnolinguistic migrations from ca. 5,000 years ago based on historical nation-states and ethnic or religious concepts invented since the Middle Ages, coupled with “your” people’s main modern (or your own) paternal lineage.

Genetic origins of Minoans and Mycenaeans and their continuity into modern Greeks

mycenaean-minoan

A new article has appeared in Nature, Genetic origins of the Minoans and Mycenaeans, by Lazaridis et al. (2017), referenced by Science.

Abstract:

The origins of the Bronze Age Minoan and Mycenaean cultures have puzzled archaeologists for more than a century. We have assembled genome-wide data from 19 ancient individuals, including Minoans from Crete, Mycenaeans from mainland Greece, and their eastern neighbours from southwestern Anatolia. Here we show that Minoans and Mycenaeans were genetically similar, having at least three-quarters of their ancestry from the first Neolithic farmers of western Anatolia and the Aegean, and most of the remainder from ancient populations related to those of the Caucasus3 and Iran. However, the Mycenaeans differed from Minoans in deriving additional ancestry from an ultimate source related to the hunter–gatherers of eastern Europe and Siberia, introduced via a proximal source related to the inhabitants of either the Eurasian steppe or Armenia. Modern Greeks resemble the Mycenaeans, but with some additional dilution of the Early Neolithic ancestry. Our results support the idea of continuity but not isolation in the history of populations of the Aegean, before and after the time of its earliest civilizations.

Samples are scarce, and there is only one Y-DNA haplogroup of Mycenaeans, J2a1 (in Galatas Apatheia, ca. 1700-1200), which shows continuity of haplogroups from Minoan samples, so it does not clarify the potential demic diffusion of Proto-Greeks marked by R1b subclades.

Regarding admixture analyses, it is explicitly or implicitly (according to the press release) stated that:

  • There is continuity between Mycenaeans and living people, so that the major components of the Greeks’ ancestry was in place already in the Bronze Age, after the migration of the earliest farmers from Anatolia.
  • Anatolians may have been the source of “eastern” Caucasian ancestry in Mycenaeans, and maybe of early Indo-European languages (i.e. earlier than Proto-Greek) in the region.
  • The “northern” steppe population (speaking a Late Indo-European dialect, then) had arrived only in mainland Greece, with a 13-18% admixture, by the time studied.
  • Samples before the Final Neolithic (ca. 4100 BC) do not possess either type of ancestry, suggesting that the admixture detected occurred during the fourth to second millennium BC.
  • Admixture from Levantine or African influence (i.e. Egyptian or Phoenician colonists) cannot be supported with admixture.

All in all, there is some new interesting information, and among them the possibility of obtaining ancient DNA from arid regions, which is promising for future developments in the field.

EDIT (20/8/2017): The article received widespread media attention, and two blog posts were linked to by the main author in his Twitter account: Who are you calling Mycenaean?, and On genetics and the Aegean Bronze Age. Apart from the obviously wrong reductio ad Hitlerum that pops up in any discussion on Indo-Europeans or genetics (even I do it regarding fans of admixture analysis), I don’t know why these created so much fuss (and hate) among geneticists. There seems to be a war brewing between Archaeology and Genetics.

Razib Khan writes The Revolution Which Came To Archaeology Without Archaeologists?, and I guess this is how many people feel in the field, but if they had studied some minimal archaeology of the samples they are studying they would know that their conclusions would come as no surprise, in any case. They can solve old archaeological questions, and they can help create new hypothesis. That’s it. Regarding the study Mr. Khan believes did come as a surprise to archaeologists, that on Bell Beakers, I would like to remind him of the predictions Volker Heyd did about genetics already in 2007, based only on Archaeology.

Another nail in the coffin for the Anatolian hypothesis: continuity and isolation in the Caucasus during the Neolithic and Calcholithic, in mtDNA samples

caucasus-armenia

A new paper appeared on Current Biology, by Margaryan et al. (including Morten E. Allentoft): Eight Millennia of Matrilineal Genetic Continuity in the South Caucasus.

Among its conclusions:

The plot clearly shows the clustering of the ancient group together with the modern European, Armenian, and Caucasian populations. We observe none of the typical East Eurasian mtDNA lineages (A, C, D, F, G, and M) among the ancient individuals, and only one individual with haplogroup D is present in the modern Armenian maternal gene pool (Artsakh). As such, the archaeologically and historically attested migrations of Central Asian groups (e.g., Turks and Mongols) into the South Caucasus [14, 15] do not seem to have had a major contribution in the maternal gene pool of Armenians. Both geographic (mountainous area) and cultural (Indo-European-speaking Christians and Turkic-speaking Muslims) factors could have served as barriers for genetic contacts between Armenians and Muslim invaders in the 11th–14th centuries CE. The same pattern was observed using Y chromosome markers in geographically diverse Armenian groups.

Also, regarding the potential Indo-European migration into the area:

It appears that during the last eight millennia, there were no major genetic turnovers in the female gene pool in the South Caucasus, despite multiple well-documented cultural changes in the region [27, 28]. This is in contrast to the dramatic shifts of mtDNA lineages occurring in Central Europe during the same time period, which suggests either a different mode of cultural change in the two regions or that the genetic turnovers simply occurred later in Europe compared to the South Caucasus. More data from earlier Mesolithic cultures in the South Caucasus are needed to clarify this. During the highly dynamic Bronze Age and Iron Age periods, with the formation of complex societies and the emergence of distinctive cultures such as Kura-Araxes, Trialeti-Vanadsor, Sevan-Artsakh, Karmir-Berd, Karmir-Vank, Lchashen-Metsamor, and Urartian, we cannot document any changes in the female gene pool. This supports a cultural diffusion model in the South Caucasus, unless the demographic changes were heavily male biased, as was most likely the case in Europe during the Bronze Age migrations [29, 30]. However, genome-wide data from the few Bronze Age individuals published so far from the South Caucasus also support a continuity scenario [26]. Another possibility is that any gene flow into the South Caucasus occurred from groups with a very similar genetic composition, facilitating only subtle genetic changes that are not detectable with the current datasets.

I would obviously support the latter possibility, a demic diffusion that can be shown by precise subclade and admixture analyses, because cultural diffusion is quite difficult to justify in any ancient setting. Since it is most likely south-eastern European R1b-Z2103 lineages (or R1b-M269, if resurged during the proto-language transition in the Balkans) the original marker of Palaeo-Balkan speakers, that is what one should be looking for in Y-DNA investigation in the area. Since migrations were probably male-biased, it is not likely that mtDNA was much affected. But, especially during the Iron Age, a change should also be seen, marked by the appearance of (recent) U subclades.
