I think there were,i think black skin and white skin is a mutation,there seem to be more brown people,
White skinned blue eyed people there melanin cell mutated and adabted to the enviroment of north(northern europe,caucasia,central asia)melanin in their skin,hair,eyes reduced)and maybe also diet
Black african there skin adapted to there enviroment,doesnt explain why arabs arent black,and i think it was @Apollo that wrote they might have intermated with other sapiens,most sub saharan african have sickle cell anemia as an adaptation to fight malaria
Just a thought
