Survival of hunter-gatherer ancestry in West-Central European Neolithic

Recent papers on France and neighbouring regions, Ancient genome-wide DNA from France highlights the complexity of interactions between Mesolithic hunter-gatherers and Neolithic farmers, by Rivollat et al.

I. Survival of HG ancestry in Central Europe

From Rivollat et al. (2020):

Here, we present newly typed genome-wide data from 101 individuals from 12 sites from modern-day France and Germany (3 Late Mesolithic and 98 Neolithic, 7000–3000 cal BCE (…)

Maros shows Yamnaya-derived East BBC ancestry and local admixture

bronze-age-danubian-eba

New preprint Kinship, acquired and inherited status, and population structure at the Early Bronze Age Mokrin necropolis in northern Serbia, by Zegarac et al. bioRxiv (2020).

Intersesting excerpts about this 2100-1800 BC cemetery (emphasis mine):

Ancestry

The individual Mokrin genomes are best modelled as a mixture of Central European hunter-gatherers, Aegean Neolithic farmers and influences from the Eastern European steppes (mean qpAdm tail probability individually 0.46, pooled 0.08).

We observed no significant variation in the eastern European steppe-like component between individuals. Pooling individuals, admixture proportions are estimated to be around 8% (± 1.2% SE) western hunter gatherers, 55% (±

Early arrival of Steppe ancestry in Switzerland

late-neolithic-western-europe

Open access paper Ancient genomes reveal social and genetic structure of Late Neolithic Switzerland by Furtwängler et al. Nat. Commun. (2020).

Interesting excerpts (emphasis mine):

The ancient individuals from this study originate from 13 Neolithic and Early Bronze Age sites in Switzerland, Southern Germany, and the Alsace region in France. All samples taken from the individuals were radiocarbon dated.

The arrival of Steppe ancestry

Two distinct clusters can be identified and were also confirmed by ADMIXTURE analysis, one consisting of individuals dating to 4770–2500 calBCE, and one comprising individuals dating to 2900–1750 calBCE. The oldest individuals from the sites of

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”

A very “Yamnaya-like” East Bell Beaker from France, probably R1b-L151

bell-beaker-expansion

Interesting report by Bernard Sécher on Anthrogenica, about the Ph.D. thesis of Samantha Brunel from Institut Jacques Monod, Paris, Paléogénomique des dynamiques des populations humaines sur le territoire Français entre 7000 et 2000 (2018).

A summary from user Jool, who was there, translated into English by Sécher (slight changes to translation, and emphasis mine):

They have a good hundred samples from the North, Alsace and the Mediterranean coast, from the Mesolithic to the Iron Age.

There is no major surprise compared to the rest of Europe. On the PCA

Minimal Corded Ware culture impact in Scandinavia – Bell Beakers the unifying maritime elite

Abstract (emphasis mine):

Along the western Norwegian coast, in the northwestern region of the Nordic Late Neolithic and Bronze Age (2350–500 BCE) there is cultural homogeneity but variable expressions of political hierarchy. Although new ideological institutions, technology (e.g., metallurgy and boat building), intensified agro‑pastoral farming, and
