Super excited to share our two papers published in Nature today! 🧬 We use ancient genomics to explore how Germanic and Celtic languages spread across Europe. Here's a video of our findings, produced by Nicolas Delgado Clausen!

Today we're sharing with you all the name of the next Elder Scrolls title (did you guess correctly?).

It’s not all about polygenic scores.
Some striking population differences involve particular variants, whole-gene deletions or extra gene copies.
Here are examples involving appearance, alcohol reactions, digestion and parasite defence. 🧵

Y-DNA and MtDNA of Early Medieval Saxony-Anhalt Slavs.
Although migration period sampling is very scarce these represent the main patrilineages of Prague-Korchak upon arrival.

There will be a aDNA study on the Greek/Eastern Mediterranean component in Italy with 500 new samples.

Reconstructed face of a 2,000 years old Roman soldier.
Who was this brutally murdered man? The researchers think he was more likely to have been a regular soldier than an officer.
At around 1.90 metres, the man was surprisingly tall for the time and very muscular. Archaeologists in the early 1980s therefore suggested that he might have been a Frisian. The latest dating methods led the team to a different conclusion: isotopes in the man’s tooth enamel indicate a childhood spent in Southern Europe.

PCA Projection of the main Imenkovo clusters taken from Leonid Vyazov’s video essay and qpAdm BA-IA Modeling
Cluster A is closest to what Early Kiev would’ve looked like although it and B have excess Iranic ancestry possibly from the preceeding Late Sarmatian burials in the area

Contrasting demographic impacts of Roman colonization and early medieval migrations in the Iberian Peninsula
Highlights
• 245 ancient genomes revealing Roman and early medieval Iberian diversity
• Roman rule transformed Iberia into a genetically diverse population mosaic
• Eastern Mediterranean and North African ancestry spread widely in Iberia
• Migration period elites contributed ancestry without major population replacement

A simplified phylogenetic tree schematic to visually represent the recent findings on the emergence of modern humans.
– It also shows ancient source components relevant for later groups (e.g. OOA-like, European or East Asian HGs, ANE, etc.), not modern populations...

Distribution of Slavic sites in Romania and Moldova during the Migration Period.
These groups are the result of Prague-Korchak and Penk'ovka diffusing into the region and fusing into a homogeneous horizon, although ethnically these are identified mainly as Antes.

Yamnaya, Corded Ware and Bell Beaker haplogroup similarity.
20 / 135 (14.8%) of Corded Ware have a clade from Yamnaya
156 / 179 (87.2%) of Bell Beaker have a clade from Corded Ware
Using a clade depth of 11 from the first 3 digits

David massively revised his preprint. Check out the new version!
Some highlights are more evidence for why range expansion specifically works better than an admixture pulse and what genes may have been inherited from the expanding "mode 3" population

1) Ancient DNA comes often with bad coverage. You can fill the gaps statistically using GLIMPSE fairly standard practice. The obvious worry however is does that quietly drag the ancient genome toward the moderns you borrowed from in Admixtools? So I tested it. 🧵
ALT PCA of Imputed Genomes side by side with regular capture data.
Gregor Mendel, the godfather of genetics, carried Y-DNA R1a and mtDNA H1c1. On smartPCA, he falls between West Slavs and Northern/Western Europeans, typical of eastern Germans and Austrians. Distal qpAdm: 46.7% Samara Yamnaya, 40.4% Barcin ANF, 12.9% Loschbour WHG (p=0.301).
