    I have absolutely no known ancestry even an inkling of it from Papua New Guinea, but I get a trace of it with several calculators..... that and S. Asian (Bengali). Maybe an ancient bring back from Marco Polo's travels or something....

    I wonder how the Hòabìnhian hunter gatherers of Southeast Asia fit into this picture: https://www.sciencealert.com/8-000-y...igration-china

    I wonder how true that is.Papuans and Aboriginals both appear to cluster genetically with East Eurasians,and Australoids historically have intermixed with Southeast Asians alot more than South Asians historically.This explains the existence of Oceania itself and whole populations like Polynesians,Micronesians,and Wallaceans.I would barely even count South Indians and Sri Lankans as actually Australoid admixed unlike the former groups.

    AASI is also East Eurasian.

    East eurasians branch off into northern (east asian) and southern (australoid). These two are very distantly related to each other and not close at all. Indians have direct contribution from the southern (australoid). And if you look at any pca you can see papuans/melanesians form a point at the bottom away from east asians, and indians are on a cline directly toward them. So there is a real, direct connection

    Yup onge, aasi, papuans, hoabhinians are all australoid and share a common root, they're like cousins

    Papuans are more related to even Han than some of the most AASI South Indians which isn't surprising since both East Asians and Papuans are >95% East Eurasian/ENA while Irula has significant West Eurasian ancestry as well.

    I don't see any reason to believe that AASI/Onge/Australasian populations all come from one clade to the exclusion of East Asians?
    I think there must be some more complex history of admixture especially when you also add ancient populations like Tianyuan.
    See for example the Hoabinhian paper(https://www.biorxiv.org/content/10.1101/278374v1.full) where East Asians are modelled as a mixture of something related to Onge(3/4) and something related to Tianyuan(1/4).
    IIRC I've also seen the proportions reversed(IE East Asian being mostly Tianyuan-like).

    Unfortunately we don't have any AASI-samples but my guess would be that they were a mix of Onge/Hoabinhian-related and something "even more indigenous" probably with lots of substructure as well over the Indian subcontinent.
    But perhaps someone with more knowledge could correct me.
