Darker skin pigmentation in the ancestors to all humans may have been an adaptation to increase UV- resistance that followed the loss of fir in early hominids. The subsequent loss of pigmentation in at least two human populations may have conferred what advantage in those populations, both of which inhabited areas with less sun exposure?
