[QUOTE]Originally posted by DD'eDeN: [QB] All black-skin people today had long-ago white-skin ancestors with non-white hair (so obviously not albino). So there has been an ancestral melanising process (from rainforest outwards) and more recently an albanizing process (from tropics polewards). Comparable sequence occurred in the peppered moth. http://www.bing.com/search?q=peppered+moth&src=IE-TopResult&FORM=IE10TR Regarding the True Arab, heavy clothing & tents reduce direct (UV & IR) sunlight exposure, while camouflage is less significant in herders than hunters but still important in protecting herds. In The Road To Ubar, there is a reference to Mahra herding goats in canyons, canyons have much sharper sun-shadowing than open plains or deserts, dark skin would provide camouflage better than light skin there.
