- West Eurasians appear to have become less Mediterranean and Near Eastern after the Neolithic, or even the Copper Age.Feel free to post your own inferences from the data in the comments below. I'll try this again when more genomes roll in. I'm expecting quite a few to be published next year, especially from Central and Eastern Europe. Fingers crossed.
- Populations closely related to MA-1 had a profound impact on the genetic structure of almost all West Eurasians and South and Central Asians.
- West Eurasians share basically the same ancestral components, although often in very different proportions (which unfortunately the f3-stats aren't able to show).
- The only groups in Europe that are better fitted as mixtures of Stuttgart and Loschbour or La Brana-1, as opposed to Stuttgart and MA-1, are found in southwestern Europe, which just happens to be the most distant part of Europe from the Eastern European/Central Asian steppe.
- Turkic and Uralic groups generally show stronger signals of admixture with the Saqqaq as one of the reference genomes than the Indo-Europeans.
- Only two European groups, Lithuanians and Finns, are better fitted as Gokhem2/MA-1 than Stuttgart/MA-1, probably because they harbor the lowest levels of Near Eastern ancestry in this analysis.
- None of the European populations has any of the post-Copper Age genomes near the top of their stats, which suggests that the present-day European genetic structure formed very rapidly during or just after the Copper Age.
By the way, on a related note, here's a new paper on isotope data from various steppe groups, including Yamnaya:
A Multi-Isotopic Approach to the Reconstruction of Prehistoric Mobility and Economic Patterns in the West Eurasian Steppes 3500 to 300 BC
Every bit of new information on this very exciting topic is welcome, and I really don't want to sound ungrateful, but after reading that the first thing that came to my mind was thank God for ancient DNA.
