In my recent post about the origin and expansion of haplogroup R1b-L51, Chetan made an interesting comment on the origin and expansion of R1a-Z645. Since this haplogroup is also relevant for European history and dialectal North-West Indo-European and Indo-Iranian expansion, I feel compelled to do a similar post, although the picture right now is more blurry than that of R1b-L51.
I find it interesting that many geneticists would question the simplistic approach to the Out of Africa model as it is often enunciated, but they would at the same time consider the current simplistic model of Yamna expansion… Read the rest “On the origin and spread of haplogroup R1a-Z645 from eastern Europe”
(Continued from the post Corded Ware culture origins: The Final Frontier).
Looking at the PCA of Wang et al. (2018), I realized that Sredni Stog / Corded Ware peoples seem to lie somewhere between:
- the eastern steppe (i.e. Khvalynsk-Yamna); and
- Lower Danube and Balkan cultures affected by Anatolian- and steppe-related (i.e. Khvalynsk-Novodanilovka) migrations.
This multiethnic interaction of the western steppe fits therefore the complex archaeological description of events in the North Pontic, Lower Danube, and Dnieper-Dniester regions. Here are some interesting samples related to those long-lasting contacts:
1. I3719 (mtDNA H1, Y-DNA I2a2a) Ukraine Neolithic sample … Read the rest “Trypillia and Greece Neolithic outliers: the smoking gun of Proto-Anatolian migrations?”
As you can imagine from my latest posts (on kurgan origins and on Sredni Stog), I am right now in the middle of a revision of the Corded Ware culture for my Indo-European demic diffusion model, to see if I can add something new to the draft. And, as you can see, even with ancient DNA on the table, the precise origin of the Corded Ware migrants – in spite of the imaginative efforts of the Copenhagen group to control the narrative – are still unknown.

I wanted to repeat what I said last week in two different posts (see on the new Caucasus and Yamna Hungary samples, and on local groups in contact with Yamna settlers).
We already knew that expanding East Bell Beakers had received influence from a population similar to the available Globular Amphorae culture samples.
- Without Yamna settlers, but with Yamna Ukraine and East Bell Beaker samples, including an admixed Yamna Bulgaria sample (from Olalde & Mathieson 2017, and then with their Nature 2018 papers), the most likely interpretation was that Yamna settlers had received GAC ancestry probably during

I wrote a series of posts at the end of 2017 / beginning of 2018, to answer the wrong assumptions I could read in forums and blogs since 2015.
I decided not to publish them then, seeing how many successive papers were confirming my Indo-European demic diffusion model in a (surprisingly) clear-cut way.
Nevertheless, because I keep reading the same comments no matter what gets published, even in mid-2018 – the latest ones in our Facebook page (“was haplogroup X Indo-European?”), and in this very blog (“I see it very difficult to link Bell Beaker with Balto-Slavic, when now Balto-Slavic … Read the rest “The R1b-L23/Late PIE expansions, and the ‘R1a – Indo-European’ association”
I wrote recently about Anthony’s new model of Corded Ware culture expansion from Yamna settlements of Hungary. I am extremely sceptic about it in terms of current genetic finds, and suspicious of the real reasons behind it – probably misinterpretations of the so-called ‘Yamnaya ancestral component’ in recent genetic papers, rather than archaeological finds.
Nevertheless, it means a definitive rejection by Anthony of:
- The multiple patron-client relationships he proposed to justify a cultural diffusion of Late Indo-European dialects from Yamna into different Corded Ware cultures in the forest-steppe and Forest Zone (see one of his latest summaries of the

I recently wrote about the Indo-European Corded Ware Theory of Kristian Kristiansen and his workgroup, a sort of “Danish school”, whose aim is to prove a direct, long-lasting interaction between the North Pontic steppe and east European cultures during the Late Neolithic, which supposedly gave rise to a Late Indo-European-speaking Corded Ware culture. That is, a sort of renewed Kurgan model; or, more exactly, Kurgan models, since there is no single one preferred right now.
David Anthony had remained more or less in the background after the controversial assessment of the so-called Yamnaya ancestral component by recent … Read the rest “The new “Indo-European Corded Ware Theory” of David Anthony”
New open access article, Genome diversity in the Neolithic Globular Amphorae culture and the spread of Indo-European languages, by Tassi et al. (2017).
It is unclear whether Indo-European languages in Europe spread from the Pontic steppes in the late Neolithic, or from Anatolia in the Early Neolithic. Under the former hypothesis, people of the Globular Amphorae culture (GAC) would be descended from Eastern ancestors, likely representing the Yamnaya culture. However, nuclear (six individuals typed for 597 573 SNPs) and mitochondrial (11 complete sequences) DNA from the GAC appear closer to those of earlier Neolithic groups than to

I published an essay (or “dissertation”) some weeks ago, about what seems to me one of the most likely models of expansion of Indo-European-speaking peoples, based on Y-DNA haplogroups. Recently J.P. Mallory had proposed* (although he was not the first) that North-West Indo-European (the ancestor of Italo-Celtic and Germanic, and Balto-Slavic**) expanded with the Bell Beaker culture, a hypothesis that is supported by the most recent radiocarbon data (and subsequent proposal of an eastern origin of the pre-Bell Beaker culture, linked to the Yamna expansion, by Volker and Heyd). As I outline in the paper, ancient DNA samples and … Read the rest “Indo-European Demic Diffusion – The expansion of Proto-Indo-Europeans potentially explained as the expansion of R1b subclades”
