    Forgive me for my different opinions.

    I think we should divide the ancients 40k years ago into two categories. The first category includes IUP-BKs, (y-C1 and mt-M), they are likely to be related to the later GoyetQ116-1, IUP-BKs go deep into Europe and harbor a relatively high proportion of Neanderthal ancestry. Europe is the last refuge of Neanderthals. Therefore, IUP-BKs have a similar situation to Papuans in Southeast Asia -- they are unlikely to expand abroad. Later, the volcanic eruption in Italy was a fatal blow to IUP-BKs, but they were not extinct. There is only one sub branch of y-C1 in Europe, and the combination of y-C1 and mt-M suggests that they come from east Eurasia, and they have been mixed with west Eurasians.

    The second category includes UstIshim and Tianyan (y-K2). Compared with IUP-BKs, they are far away from Europe and harbor a lower proportion of Neanderthal ancestry. It is well known that y-K2 branch is very successful. There is one exception to the K2 branch (Oase1). Unfortunately, he went in the wrong direction. I think Tianyuan comes from west Eurasia.

    According to figure 1 of Hajdinjak et al. 2021, UstIshim and Tianyan have no IUP context. In fact, most early East Eurasians did not use blade technology at all, they use stone tools that are still backward than Neanderthals. It is not a good idea to track the gene flow of Homo sapiens with stone technology. At least it is unfair to the people in east Eurasia.

    Ust-Ishim man has no context at all. The single bone of Ust-Ishim man was found literally laying on the bank of the river by an artist who carves bone figurines, he didn't realize it was a human bone. So we don't know archaeological association of Ust-Ishim man, he may have used IUP tools, but we don't know.

    You are right that EHG and WHG basically are the same population except that the former have an higher contribution of ANE. This map basically tells the whole story of european hunters. Common West Eurasian is ancestral to both WHG and EHG. EHG is different because it has something like 9% ANE. Common West Eurasian is the father of WHG and EHG

    This model seems inaccurate since modern Northern Europeans have around 25% ANE ancestry, and there are also major differences in EHG/WHG phenotypes.
