    OOA Question

    Hi,

    I came across two models one which suggest single OOA and repopulation of eurasia from India, and other which suggests a split of OOA into west eurasia and east eurasia (specifically east asians) and India being the admix between these west and east split lineages.

    Both models are quite different, I wanted to know what is the consensus/evidence for each model.


    Thanks,

    80kya: Humans leave Africa and enter the middle east
    ?kya: the people in the middle east split into two; one group is called 'basal eurasians', the other group is 'crown eurasians' ancestral to both east and west eurasians
    50kya: the crown eurasians split (I don't think we know exactly where, northern middle east/central asia maybe, India possible I suppose) into west and east
    - west splits into european and siberian/central asian (ANE) branches
    - east splits into an indian, oceanian, and asian branches (all 3 roughly equally related)
    20kya: asian and ANE meet somewhere in northeast asia, becoming native americans
    10kya: here is what eurasia looks like
    - Europe: predominantly the same people that have been there since 40kya, with a gradient of ANE towards the northeast
    - Middle east: Anatolia, Levant population is a mix of european + basal, in Iran + Caucasus the population is a mix of mostly ANE + basal
    Neolithic:
    - Anatolians move into Europe
    - Iranians move into India

    That's a gross overview...
