HPGL @ Stanford has a new paper up at their site titled The Levant versus the Horn of Africa: Evidence for Bidirectional Corridors of Human Migrations (PDF). Samples from Egypt & Oman tend to show an affinity with West Eurasian haplogroups with some admixture of Sub-Saharan ones, but the article focuses on the dynamics in northern Sub-Saharan Africa far more than the title indicates. I found this aside interesting:
mtDNA data in African populations…suggest a lower importance of language versus geography in defining differences among the main groups in the female genetic pool. This may reflect a general pattern of cultural assimilation of the indigenous females during the Bantu expansion….
The combination of periodic male population movements on the macro scale and dominance of exchange of females between villages and localities on the micro scale is something that needs to be systematized more. As usual, the men show a greater tendency toward extremes….
