Very difficult to tell if the East Asian phenotype is the result of the costal migration or the eastern migration across the Tibetan range. My instinct would have been the former, but the most current data I’ve seen suggests the latter pretty strongly. And that the East Asian phenotypic expansion was as dramatic as it looks. So I’m stuck with that until we have a theory with better supported data. Unfortunately, while we have a lot of genetic history in europe we are going to take a bit longer to catch up in East Asian DNA.
