[QUOTE]Originally posted by Tukuler: [QB] [QUOTE]Originally posted by the lioness,: [qb] Haplogroup U descends from the haplogroup R mtDNA branch of the phylogenetic tree. The defining mutations (A11467G, A12308G, G12372A) are estimated to have arisen between 43,000 and 50,000 years ago, in the early Upper Paleolithic Ancient DNA classified as belonging to the U* mitochondrial haplogroup has been recovered from human skeletal remains found in Western Siberia, which have been dated to c. 45,000 years ago ( Ust’-Ishim ) [/qb][/QUOTE]Thank you. U cometh from R. U is 2nd step from N. I'm not saying U6 boarded a flight or set sail directly to Morocco. Of course it crossed thru the part of AME* called SW Asia among other names. To me since the oldest U6 known is in Roumania for now any other origin is non-parsimonious speculation that could turn out correct by some later unknown find. But for now a an aDNA fossil at hand is worth. Age, frequency, diversity of U6a'b'd'c seem to weight the African pan of the coalescence and expansion scale. Afaic they're just as indigenous African as those L clades which're younger. The Africa we know is a child of Mid Holocene monsoon withdrawal. Will add some quotes later unless somebody beats me to it. - - - * [b]A[/b]frica and the [b]M[/b]iddle [b]E[/b]ast [/QB][/QUOTE]
