1/10 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. Chart style inspired by @Maptysk
The distribution of Prague-Korchak, otherwise ethnically associated with the Sclaveni mentioned in Byzantine sources. Just like all other Early Slav groups it descends from the Kiev Culture and is ancestral to West and East Slavs.

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. universiteitleiden.nl/en/new…

Distribution of the Kyiv culture during the Late Roman Period Kyiv's origin is mainly Zarubintsy with influences from the synchronous Chernyakhov and served as the basis for Penk'ovka, Kolochin and Prague-Korchak. It also had a parallel Volga variant.

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
Distribution of Imenkovo Culture in the Volga during the Migration Period (possibly Antes ethnically) They mostly share similarities with Late Zarubintsy, as well as Przeworsk and some from Chernyakhov

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 cell.com/cell/fulltext/S0092…

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
Updated and Corrected version accounting for missing samples and with deeper clades (Clade depth of 11 from the first 3 digits) Corded Ware has 20 / 135 samples on the same Clade as Yamnaya, which is a 14.8% similarity.

Female skeleton (16–20 years) from Spain dated to the 8th–5th centuries BC shows a genetic profile of North Iberian with a high proportion of Steppe ancestry and mitochondrial haplogroup U5a1, typical of Western European Mesolithic hunter-gatherers.

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 biorxiv.org/content/10.64898…
New solo paper from David Reich might provide some clarity to the Muddle in the Middle. Maybe Humans and Neanderthals are both hybrids of an old expansion of the "MSA population" and local European / African humans:

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. 🧵

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).
Prominent scientist Gregor Mendels Y-DNA has been determined to be R1a and his mitochondrial (mtDNA) is H1C1. In terms of physical characteristics, he had blue eyes, brown hair, and fair skin, along with a tendency towards baldness.

Not surprising on the result of new Sintashta samples, but nevertheless always great with new samples. Ancient DNA analysis identified the Y-chromosome haplogroup R1a1a1b2a (Z94). Also evidence of a well-healed intravital trepanation was identified, which in terms of the technique (scraping), has the closest analogies among people of the Middle Volga Abashevo culture. nav.jvolsu.com/index.php/en/…

This paper argues that Scandinavian Mesolithic hunter-gatherers, particularly Early Mesolithic groups in Denmark, may have hunted with poisoned arrows, and that this could explain the prevalence and design of their tiny microlithic projectile points. sciencedirect.com/science/ar…

Napoleon was not only a military genius but a polymath who was elected to France’s premier intellectual institution. He could pick up almost anything: his literary criticism impressed Goethe, he could debate mathematical theory with Laplace, and his knowledge of music impressed Berlioz.
