[QUOTE]Originally posted by Ish Gebor: [QB] ^ So what ethnic group has the most / highest of this V88 clade? He is a Nkombe Cameroonian. Some of the chromosome buildup of Hg R have been traced back to Africa, before the out of Africa occurred, which means the BASAL is right there in Africa. So your theory makes no sense, but here is the math! [QUOTE]The population of [b]AMH spreading in the eastern direction included “softened” Mongoloid elements[/b]. The “dialectal continuum” consisting of Proto-Uralic, Proto-Altaic and Palaeo-Siberian- related languages formed the principal communication media of Early Modern Humans in northern Eurasia.

[QUOTE] deepest branching separates A1b from a monophyletic clade whose members (A1a, A2, A3, B, C, and R) all share seven mutually reinforcing derived mutations (five transitions and two transversions, all at non-CpG sites). […] The phylogenetic relationships we observed among chromosomes belonging to haplogroups B, C, and R are reminiscent of those reported in the tree by Karafet et al.13 [b]These chromosomes belong to a clade (haplogroup BT) in which chromosomes C and R share a common ancestor (Figure 2).[/b][/QUOTE]--Fulvio Cruciani A Revised Root for the Human Y Chromosomal Phylogenetic Tree: The Origin of Patrilineal Diversity in Africa [QUOTE] When counting from the split of hg DE on the unrooted phylogenetic tree, MA-1 is determined to be carrying the derived allele in 183 sites and the ancestral allele in 1706 sites. [i][b]The position of MA-1 on the phylogenetic tree is established by the state of the 313 basal mutations separating hgs DE and R, where MA-1 has 143 informative positions. [/b] [/i] Of these, 138 are in the derived and 5 in the ancestral state, placing MA-1 as a lineage basal to hg R. With only a few exceptions characterized below, all other informative positions in MA-1 are in the ancestral state, further supporting the phylogenetic positioning of MA-1 on the tree.

[QUOTE]The lack of Late Pleistocene human fossils from sub-Saharan Africa has limited paleontological testing of competing models of recent human evolution. We have dated a skull from Hofmeyr, South Africa, to 36.2 ± 3.3 thousand years ago through a combination of optically stimulated luminescence and uranium-series dating methods. The skull is morphologically modern overall but displays some archaic features. Its strongest morphometric affinities are with Upper Paleolithic (UP) Eurasians rather than recent, geographically proximate people. [b]The Hofmeyr cranium is consistent with the hypothesis that UP Eurasians descended from a population that emigrated from sub-Saharan Africa in the Late Pleistocene.[/b][/QUOTE]--F. E. Grine et al.
