Early Uralic – Indo-European contacts within Europe

north-west-indo-european-uralic

One of the most interesting aspects for future linguistic research, boosted by the current knowledge in population genomics, is the influence of Uralic – most likely spread initially with Corded Ware peoples across northern Europe – on early Indo-European dialects.

Whereas studies on the potential Afroasiatic (or Semitic), Vasconic, Etruscan, or non-Indo-European in general abound for ancient and southern IE branches (see e.g. more on the NWIE substrate words), almost exclusively Uralicists have dealt with the long-term mutual influences between Indo-European and Uralic dialects, and often mostly from the Uralic side.… Read the rest “Early Uralic – Indo-European contacts within Europe”

Spread of Indo-European and Uralic speakers in ADMIXTURE

indo-european-uralic-admixture

The following are updated files for unsupervised ADMIXTURE of most available ancient Eurasian samples with K=7. For reference, see PCA of ancient and modern Eurasian samples.

NOTE. For a precise interpretation of ancestry evolution, be sure to first check the posts on the expansion of “Steppe ancestry”, on the spread of Yamnaya ancestry with Indo-Europeans, and on the evolution of Corded Ware ancestry typical of modern Uralic populations.

ADMIXTURE timeline

This is a YouTube video similar to the one on Indo-Europeans and Y-DNA evolution:

The expansion of Indo-Europeans in Y-chromosome haplogroups

yamnaya-corded-ware-y-dna-haplogroups

I have compiled for two years now the reported Y-DNA and mtDNA haplogroups of ancient DNA samples published, including also SNPs from analysis of the BAM files by hobbyists.

EDIT (2 FEB 2020): I have published the All Ancient DNA dataset and updated OpenLayers maps in this post, now also divided by ages.

Y-DNA timeline

Here is a video with a timeline of the evolution of Indo-European speakers, according to what is known today about reconstructed languages, prehistoric cultures and ancient DNA:

R1b-L23-rich Bell Beaker-derived Italic peoples from the West vs. Etruscans from the East

final-bronze-age-italy

New paper (behind paywall) Ancient Rome: A genetic crossroads of Europe and the Mediterranean, by Antonio et al. Science (2019).

The paper offers a lot of interesting data concerning the Roman Empire and more recent periods, but I will focus on Italic and Etruscan origins.

NOTE. I have updated prehistoric maps with Y-DNA and mtDNA data, and also the PCA of ancient Eurasian samples by period including the recently published samples, now with added sample names to find them easily by searching the PDFs.

“Steppe ancestry” step by step (2019): Mesolithic to Early Bronze Age Eurasia

yamnaya-gac-maykop-corded-ware-bell-beaker

The recent update on the Indo-Anatolian homeland in the Middle Volga region and its evolution as the Indo-Tocharian homeland in the Don–Volga area as described in Anthony (2019) has, at last, a strong scientific foundation, as it relies on previous linguistic and archaeological theories, now coupled with ancient phylogeography and genomic ancestry.

There are still some inconsistencies in the interpretation of the so-called “Steppe ancestry”, though, despite the one and a half years that have passed since we first had access to the closest Pontic–Caspian steppe source populations. Even my post “Steppe ancestry” step by step from a year ago … Read the rest ““Steppe ancestry” step by step (2019): Mesolithic to Early Bronze Age Eurasia”

Corded Ware and Bell Beaker related groups defined by patrilocality and female exogamy

tumulus-culture-eba-danube

Two new interesting papers concerning Corded Ware and Bell Beaker peoples appeared last week, supporting yet again what is already well-known since 2015 about West Uralic and North-West Indo-European speakers and their expansion.

Below are relevant excerpts (emphasis mine) and comments.

#UPDATE (27 OCT 2019): I have updated Y-DNA and mtDNA maps of Corded Ware, Bell Beaker, EBA, MBA, and LBA migrations. I have also updated PCA plots, which now include the newly reported samples and those from the Tollense valley, and I have tried some qpAdm models (see below).

Bell Beakers and Mycenaeans from Yamnaya; Corded Ware from the forest steppe

eba-yamnaya-ancestry-hungary

I have recently written about the spread of Pre-Yamnaya or Yamnaya ancestry and Corded Ware-related ancestry throughout Eurasia, using exclusively analyses published by professional geneticists, and filling in the gaps and contradictory data with the most reasonable interpretations. I did so consciously, to avoid any suspicion that I was interspersing my own data or cherry picking results.

Now I’m finished recapitulating the known public data, and the only way forward is the assessment of these populations using the available datasets and free tools.

Understanding the complexities of qpAdm is fairly difficult without a proper genetic and statistical background, which I … Read the rest “Bell Beakers and Mycenaeans from Yamnaya; Corded Ware from the forest steppe”

Yamnaya replaced Europeans, but admixed heavily as they spread to Asia

I am currently not on holidays anymore, and the information in the paper is huge, with many complex issues raised by the new samples and analyses rather than solved, so I will stick to the Indo-European question, … Read the rest “Yamnaya replaced Europeans, but admixed heavily as they spread to Asia”
