Great question...East Asians have what are called "shovel incisors" which have a distinct anatomy not shared by Euros or Africans (or by the Indians of the sub-continent, either).

One of the main bits of evidence for Wolpoff's multi-regional hypothesis (that is, the theory that races originated early, before we were Homo sapiens but rather while we were Homo erectus) was the fact the Peking Man from 400,000 years ago also had shovel incisors. That's why this was so important to the researchers: if they could show that shovel incisors were "only" 35k years old, then the Peking Man similarity could be marked up to a coincidence.

Thanks Pharmboy.

But this begs another question. If American indians are descendents of east Asians then why don’t they have shovel incisors? (or do they?)
