“the earliest known American skeleton had its closest similarities with early Australians, Zhoukoudian Upper Cave 103, and Taforalt 18. The results obtained clearly confirm the idea that the Americas were first colonized by a generalized Homo sapiens population which inhabited East Asia in the Late Pleistocene, before the definition of the classic Mongoloid morphology.”
That's Australia, China and North Africa The “Australian” morphology seems to have been widespread at the end of the Pleistocene.
I think its a mistake to assume that people should be physically similar to very distant ancestors
“Powell has already noted (Powell 1995; Powell and Neves n.d.; Steele and Powell 1992, 1994) that the geographic groupings or races seen among modern peoples are at best fuzzy and at worst non-existent when examining late Pleistocene and early Holocene populations world-wide. “
Morphology can change drastically in isolated popluations. This has been demonstrated many times with island species. I don’t see why people would be any different.
Native Americans/American Indians have Sinodont (shovel) teeth (Turner) like most Northern Chinese. Kennewick Man, Spirit Cave man, etc have Sundadont teeth like most SE Asians.
Take this Journey Of Mankind based on the DNA studies of Professor Stephen Oppenheimer. Notice that the haplogroup X arrived early (25,000 ya) at Meadowcroft and became isolated there during the LGM (Last GlacialMaximum).
About 25% of the people in the Ojabiou(sp) tribe (Northern US) have haplogroup X genes, the highest in the Americas.
