[QUOTE]Originally posted by Cass/: [QB] Gene flow is bilateral. If you're arguing for a small amount of gene flow from south Levant into northern Egypt since the Neolithic, then there was gene flow the other direction. Even if asymmetrical, i.e. more gene flow one way than the other this makes little difference: "the genetic effects of asymmetry are not very different from those expected under a symmetric model" (Relethford, 1999). The only way south Levantine ancestry would accumulate in northern Egyptians over many generations with small-scale gene flow - is if the northern Egyptian population was continuously much smaller than the south Levant population: this is because over-time a population that is a lot larger in size will exert the greatest genetic impact; I showed this with migration matrices from Relethford (1999) in the thread I made on Multiregionalism. I see no evidence that Neolithic-to-Bronze Age southern Levant was significantly larger in population size to northern Egypt. They were both rather sparsely population compared to the Fertile Crescent and Upper Egypt. And there's little archaeological evidence for Mesopotamian-Egyptian contact, e.g. most of the foreign pottery or goods in northern Egypt from the Neolithic and Early/Middle Bronze Age are from the south Levant, not Fertile Crescent. You're trying to come up with 'clever' (although erroneous) ways to avoid the actual reality of these DNA results. [/QB][/QUOTE]
