[QUOTE]Originally posted by Mystery Solver: [QB] [QUOTE]Originally posted by Habari: No [/QUOTE]Alright then, cutting to the chase: [i][b]it's interesting to see that the precursors of E3a and E3b are mainly found in the Sahara corridor[/b], which could be an indication of the African dispersal through the Sahara…[/i] - Habari I questioned you on the above [highlighted] because E3 is obviously the precursor of E3a and E3b clades, as already noted, but as far as can I recall, it appears to be relatively even more rarer than its own derivative branches, or either E1 or E2 clades in its overall frequency and distribution pattern in the Sahara. E1 and E2 seem to be more widely distributed in sub-Saharan groups of West Africa, including the Cameroonian region, than those in East Africa and elsewhere on the continent. Based on samplings undertaken, which have been brought to my attention, E3 appears in highest frequencies in Ethiopian populations, and relatively lower frequencies in other sub-Saharan groups like Senegalese, the Burkina Faso Mossi and Rimaibe, Cameroonian Fulani, and so forth. E.g., [i]Both phylogeography and microsatellite variance suggest that E-P2 and its derivative, E-M35, probably originated in eastern Africa. This inference is further supported by the presence of additional Hg E lineal diversification and by the [b]highest frequency of E-P2*[/b] and E-M35* in the same region. The distribution of E-P2* appears limited to eastern African peoples. The [b]E-M35* lineage shows its highest frequency (19.2%) in the Ethiopian Oromo[/b] but with a [b]wider distribution range than E-P2*[/b].[/i] - Semino et al., [i][b]Origin, diffusion, and differentiation of Y-chromosome haplogroups E and J[/b][/i]. Don't know if it has to do with samplings undertaken thus far, or else just not brought to my attention, but E3 generally appears to be rare in the Sahara itself, in comparison to its presence in 'sub-Saharan' designated territories.
