Peopling of the Americas
check out kambiz's post at Anthropology.net on a forthcoming paper about a polymorphism found in "all" Native American populations and only in two populations of Siberians in the Asian northeast. This could mean (or not mean) a lot of things, and you can't really draw many conlusions from this, but I suppose it does lend further support to the idea that Native Americans and northeastern (asia) Siberians shared a recent common ancestor. Is this anything really new?.. and it's just one marker... Actually, I'm not really familiar with the background research on this issue of Native American/Asian/Siberian population genetics so I shouldn't say too much. I guess the competing hypothesis here is that NA could trace some of their ancestry to other Asian populations.
