Cro-magnons are diverse but more akin to Africans phenotypically than today's modern Europeans. Gene sequences that link contaminated or uncontaminated with current European populations do not change the well-documented phenotypical pattern, though there is diversity. As proponents of various racial models and concepts often make "common sense" appeals to phenotype, the results are what they are. The great genetic diversity of Africa and its role in the OOA evolutionary sequence also means that some sequences claimed to be exclusively "European" in fact developed in Africa first, whether as root types or foundational variants, before branching out to the rest of the world.
Genetic studies showing that pale skin is a relatively recent occurrence also add to the mix. Pale skin is not "exclusively" European. Variants are clearly present in Africa, and no doubt before branching out elsewhere. Mutation and change of course also occurred over time in various parts of the world, but this does not change the African foundation.
