    If these are indeed D cases, it means that there's no more real DE* cases left in Africa. While there's still a possibility for Tibetan DE* cases to be in fact M174+, there is a real Syrian DE(xM174,M96) left.

    Hypothesis

    1) DE* originated in West Eurasia
    2) D* and E* both originated in West Eurasia (see high-D Ainu and their West Eurasian autosomal tendence)
    3) Both of them migrated towards Africa and East Asia
    4) D failed in Africa and survived only in small isolated pockets; E failed in East Eurasia. Today E dominates Africa and D is restricted to isolated/mountainous populations in East Asia and South Asia
    I don't understand the motive of "back to Africa", why couldn't DE have split within Africa? Perhaps the Eastern Asian remnants of D-M174+ are the only ones who survived that particular OOA expansion?

    Ainus didn't seem to have West Eurasian tendencies according to this. They're pretty much pure East Eurasian, though perhaps an old branch.

    The Ainu did have a marginally greater affinity to West Eurasians in D stats:
    D(Yoruba, Sardinian; Ainu, X)
    Ami: -0.0035 -1.331
    Atayal: -0.0043 -1.481
    Dai: -0.0057 -2.305
    Lahu: -0.0049 -1.907
    Sherpa: -0.0031 -1.249

    Consistent but not really significant.

    Was that in the supplements? I didn't have access to that, do you have a link? The usual threshold for significance is 3, so it makes sense they didn't mention it in the main paper.

    I don't have it either, but someone posted a link to some of the supplementary info in the recent comments at Eurogenes.

    Yeah, it is pretty borderline, it may not mean anything. There is no such pull toward MA-1 or Amerindians, so it doesn't seem to be ANE.

    Okay, found it. Ainu have statistically insignificant but consistent pull towards West Eurasians compared to Sherpa, but also towards Papuans who are more distant from West Eurasians than East Eurasians are. OTOH nothing towards Amerindians or Neanderthals/Denisovans. I would really like to see those stats with an ape outgroup instead of Yoruba to ascertain it is not related to African population history.
