[QUOTE]Originally posted by Mystery Solver: [QB] [QUOTE]Originally posted by Miguel Antunes: Well Doug, when the first Humans entered Europe they were dark too, and latter lighter skin was selected, the same with other Eurasian populations. So I don't argue that when they reached those areas they were dark, only that they could not have evolved lighter skin. But it's only a proposition.[/QUOTE]UV radiation levels on the African continent, as your Jablonksi-Chaplin map demonstrates, and as other UV radiation maps show, are generally higher than that of Europe. The coastal north light toned Tamazight groups who are "outliers", in terms of skin shade gradients seen in the rest of the continent, have this feature, more likely because of historic gene flow from "Southwest Asia" and across the Mediterranean sea. If these "outlier" [in terms of skin shade] coastal North Africans underwent an "independent" parallel light skin pigmentation evolution with that of Europeans, then would studies on skin pigmentation genes not reveal this, just as it has done in the case of East Asians and Europeans?
