Northern Asia
Friday 12 October 2007
human colonization process of northern Asia
human dispersals to the Americas
Mitochondrial haplogroups
- haplogroups A, D2, G1, M7, and I
- subhaplogroups I4, N1e, G1c, M7d, M7e, and J1b2a
- haplogroups N1a and G1b by the first hypervariable segment (HVS1)
The southern Siberian mtDNA pool harbors several lineages associated with the Late Upper Paleolithic and/or early Neolithic dispersals from both eastern Asia and southwestern Asia/southern Caucasus. (17924343)
The phylogeography of the D2 lineages suggests that southern Siberia is likely to be a geographical source for the last postglacial maximum spread of this subhaplogroup to northern Siberia and that the expansion of the D2b branch occurred in Beringia 7,000 years ago. (17924343)
A detailed analysis of mtDNA gene pools of northern Asians provides the additional evidence to rule out the existence of a northern Asian route for the initial human colonization of Asia. (17924343)
