When I started ruminating in 2016 over the apparent differences between populations that kept the two-velar distinction of Indo-Tocharian, and the only two unrelated dialectal groups that showed a strong satemization trend, I believed that – much like in modern times – there would be no clear-cut division in terms of ancestry or Y-DNA haplogroups between neighbouring forest-steppe and steppe populations.
The answer to the question of interacting ethnolinguistic groups had to lie, as everything else, on the investigation of fine-scale population movements that must have put Uralic-speaking peoples as the main substratum of Balto-Slavic and Indo-Iranian.
Still, … Read the rest “RISE1.SG, R1b from Poland CWC, a likely mislabelled Balto-Slav”
Now that it has become evident that Late Repin (i.e. Yamnaya/Afanasevo) ancestry was associated with the migration of R1b-L23-rich Late Proto-Indo-Europeans from the steppe in the second half of the the 4th millennium BC, there’s still the question of how R1a-rich Uralic speakers of Corded Ware ancestry expanded , and how they spread their languages throughout North Eurasia.
Modern North Eurasians
I have been collecting information from the supplementary data of the latest papers on modern and ancient North Eurasian peoples, including Jeong et al. (2019), Saag et al. (2019), Sikora et al. (2018), or … Read the rest “Corded Ware ancestry in North Eurasia and the Uralic expansion”
Open access Population genomics of the Viking world, by Margaryan et al. bioRxiv (2019), with a huge new sampling from the Viking Age.
#EDIT (16 SEP 2020): The paper has been published in Nature.
Interesting excerpts (emphasis mine, modified for clarity):
To understand the genetic structure and influence of the Viking expansion, we sequenced the genomes of 442 ancient humans from across Europe and Greenland ranging from the Bronze Age (c. 2400 BC) to the early Modern period (c. 1600 CE), with particular emphasis on the Viking Age. We find that the period preceding the Viking Age was

Some very specific prosodic innovations affected the Balto-Slavic linguistic community, probably at a time when it already showed internal dialectal differences. Whether those innovations were related to archaic remnants stemming from the parent Proto-Indo-European language, and whether that disintegrating community included different dialects, remains an object of active debate.
The main question about Balto-Slavic is whether this concept represents a single community, or it was rather a continuum formed by two (Baltic and Slavic) or possibly three (East Baltic, West Baltic, Slavic) neighbouring communities, speaking closely related Northern European dialects, which just happened to evolve very close … Read the rest “Balto-Slavic accentual mobility: an innovation in contact with Balto-Finnic”
First look of an accepted manuscript (behind paywall), Genome-wide sequence analyses of ethnic populations across Russia, by Zhernakova et al. Genomics (2019).
There remain ongoing discussions about the origins of the ethnic Russian population. The ancestors of ethnic Russians were among the Slavic tribes that separated from the early Indo-European Group, which included ancestors of modern Slavic, Germanic and Baltic speakers, who appeared in the northeastern part of Europe ca. 1,500 years ago. Slavs were found in the central part of Eastern Europe, where they came in direct contact with (and likely assimilation of) the populations speaking

This is part of a series of posts analyzing the findings of the recent Nature papers Olalde et al.(2018) and Mathieson et al.(2018) (abbreviated O&M 2018).
The recent publication of Narasimhan et al. (2018) has outdated the draft of this post a bit, and it has made it at the same time still more interesting.
While we wait for the publication of the dataset (and the actual Y-DNA haplogroups and precise subclades with the revision of the paper), and as we watch the wrath of Hindu nationalists vented against the West (as if the steppe was in Western Europe) … Read the rest “Consequences of O&M 2018 (III): The Balto-Slavic conundrum in Linguistics, Archaeology, and Genetics”
