The mixed genetic origin of the first farmers of Europe

[davit]

Add to that the fact that West Eurasians always had a much bigger variation in body proportions and morphology than American Indians. To give you an impression, just check:

So neither West Eurasians/Caucasoids nor Subsaharan Africans (Pygmies!) have all the same proportions at all. There was quite a lot of variation within the West Eurasian sphere, this was always noted, not just for North Africa, but also for parts of the Near East, but especially South Asia, and generally for pre-LGM Upper Paleolithic specimen. Guess what, IBM WEA contribution looks to be Upper Paleolithic rather and in Tenerians Proto-Mediterranean, not coming directly from the Ice Age refugia.

There are huge individual differences in Central Europeans to this day. Some of the variation might date back to the Neolithic.

Wouldn't the South Asian diversity be caused by admixture with non West Eurasians?

To a large degree most likely yes, since the AASI heavy population are longer limbed, but on the other hand you had WEA with longer body proportions too and a wide ranging variation throughout WEA individually to this day.

I don't know about long bones, but I've seen studies comparing Amerindians who practiced agriculture with Amerindian hunters / gatherers. The study of Amerindians is very interesting, given how genetically homogeneous they are. The result is that these two groups were quite different with respect to skull morphology. So the adaptation doesn't seem to take that long.

I'd say it depends on the kind of trait we're talking about and its not like all American Indians are the same and even neighbouring foragers and farmers can have different origins. Some might have been different already even before starting to farm actually. But there are some trends among farmers under specific conditions.

This is mirrored with "Paleo American" remains that look African yet have genetic continuity with Modern Native Americans.

This makes me look forward to Gobero samples being genetically tested at some point in the future. Are those samples still kept and preserved somewhere?
