Radiating from the Southeastern Corner of the Mediterranean, this people may have an even greater influence in Y-DNA explaining a large part of the current distribution haplogroups E1b1b and J1c3 and perhaps others, some of which may now be more frequent out of Egypt due to founding effects. Also maybe the tiny percentage of L mt-DNA in Europe.
I don't know what the Pygmy pole is picking up in Europe but it's definitely not Pygmy. I think it's probably nothing much, but I named it "Forager B?" rather than naming it "noise".
Hunter-gatherer tribes in Europe were likely much closer to each other than in Africa, even though much more different over the same distances than a Neolithic Core component. Siberians don't easily get their own ethnic component in ADMIXTURE runs as San and Pygmies do. Still don't know if "Pygmy" (Forager B?) and Hadza represent anything at all, most likely not.
Basques have no or only a small "Nile Core" element. They lack many of the more colourful elements found in residual amounts in both Spaniards and the French. In general a good question is are groups with different languages/cultures/religions from their related neighbours more isolated because of said language/culture/religion, or do they have less subsequent outside influence and different cultural paths because they were isolated for other reasons (like geography) from the start? This could also explain why the Druze and others have relatively less of a "second wave" element.I suspect not many Southern, Mediterranean French were genotyped into this set, maybe there's one?
Khazars to mind, but probably mostly due to their Eastern European origins.
Corded Ware zone, and the East Slavs perhaps radiated from there into the East. It's possible that armed with this new productive food tech and maybe some other innovations for colder climates, they were finally able to go all the way to Vladivostok.
