ok. so, we’re all out of africa, right?
and one of the reasons for thinking this is ’cause there’s greater genetic diversity in african populations than non-africans suggesting, from what i understand, a population bottleneck in those groups who left africa and greater genetic drift back in the african population. (amiright?)
but, mutation rates are higher in hot climates than cold (edit: see better link re. mammals here), so couldn’t the greater genetic diversity in africans simply be a product of that effect?
see what i’m sayin’/askin’?
