    There's definitely a Basal Eurasian and separate North African group. Absolutely wild.
    I heavily suspected this would be the case.

    I guess that the north african group is likely ancestral to the first AMH in Europe aka Aurignacian and maybe Uluzzian.

    This also make quite a bit of sense considering some of the African samples I have have tiny traces of affinity to Karitiana in qpadm which only get stronger when I impute them.

One is ancestral to kostenki, around 70%+ ancestral to Sunghir and 50% ancestral to Vestonice. I suspect that this clade is also mostly ancestral to WHGs but in a different line from the one that contributed to Gravettians and Kostenki.

    The second clade was ancestral to both Goyet Aurignacian (and by extension gravettians like Vestonice which were modeled as 50% goyet) and to Yana (+ma1) on a separate line in the same second clade.

    Have you seen that model?
    Maybe you are right. FWIW I came up with a paper not long ago ( do no remember exactly which) that indicated a population very close to Goyet was the source ( named Early West Eurasian) of the west eurasian component in the Yana cluster.
    Which started my personal take that Yana could be 3/4 Aurignacian and the rest east eurasian.

    There's no ancient Villabruna cluster. They are only mixes of a lot of the same stuff as UP West Asians. This is not a pure population.

    Another way too look at it is Goyet is Yana plus Gravettian.

    So the problem is not really solved, but one should make more sense than the other?

    It seems Aurignacians are something like 10000 years older than Yana and Gravettians too are younger than Aurignacians

    Would contradict the salkhit paper which models gravettians as being goyet admixed but papers in general don't agree with one anothere.
