[QUOTE]Originally posted by xyyman: [QB] Can you grasp the significance of this? (play Jeopardy Song). So how long have the Amazigh been in Africa? Back migration my…… From the paper cited by TP. Quote(Cruciani) ===== Four subjects ([b]two Berbers from northwest Africa, one Tuareg and one Fulbe from Niger) were confirmed as belonging to clade A1a.24,29 [/b]It is worth noting that this clade was previously detected in west Africa, although at low frequencies.10,30–32 Three chromosomes from the Bakola pygmy group from southern Cameroon (central Africa) were found to carry the derived allele at V164, V166, V196, and P114 and were classified as A1b. [b]Interestingly, one chromosome from an Algerian Berber group (northwest Africa) was found to carry the derived allele at V164, V166, and V196 but carried the ancestral one at P114, implying a bipartite structure for A1b, where P114 defines an internal node.[/b] [b]Clearly, calculation of the precise age of the tree largely depends on the accuracy of the ASSUMED mutation rate[/b]. In any case, an antiquity of the root greater than that previously estimated is evident from the present tree structure. It is worth noting that A1b, long neglected in previous large-scale resequencing studies of the MSY, contributes to the older TMRCA and [b]high nucleotide diversity values that we observe[/b], highlighting the importance of targeted studies on rare haplogroups. Third,[b] contrary to previous phylogeny-based conclusions, 15,16 the deepest clades of the revised MSYphylogeny are currently found in central and northwest Africa.[/b] MSY lineages from these regions coalesce at an older time (142 KY) than do those from east and south Africa (105 KY), opening new perspectives concerning early modern human evolution. [b]A scenario of a Y chromosome ‘‘Adam’’ living in central-northwest Africa about 140 KY ago [/b]would provide a good fit to the present data. ======= As I said. More to come. Unlike DNATribes I woukd put the “basal Eurasia” gene pool not along the Nile but further South and West. [/QB][/QUOTE]
