My main problem is that I do not think that there was any proto-East Eurasian population before arrival to East Asia (or more exactly SE Asia most likely) c. 60 or 70 Ka ago, and similarly there was no proto-West Eurasian population until an Eurasian subgroup migrated westward from, probably, Pakistan (although many lineages must have reached first as far east as at least Bengal: Y-DNA P and mtDNA N and R) c. 50 Ka ago. <br /><br />I'd say that there was no divergence west of Burma, after all Europeans, Chinese and Papuans share a lot of dominant lineages within Y-DNA MNOPS and mtDNA R, what precludes any "early" divergence before arriving together to at least Bengal. Hence the admixture should (if not "must") have been a unique event.<br /><br />Also we discussed recently other "evidence" in favor of this difference and I underlined that while some minor elements are different most are the same and hence must be a matter of drift after divergence between these two populations. <br /><br />But well, I think that this matter is less important and also less clear than the other: the likelihood that "Denisovan" admixture is nothing but a proxy for that from Homo erectus.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.com
