computer calculation of what humans looked like 70,000 years ago based on combining an ancient skull with the face of a modern African tribe from an ancient lineage


One of my beliefs is that Africans have genetically preserved an extremely ancient phenotype , or at least preserved more of that phenotype than non-Africans.  While I may never be able to prove this in full, and educated commenters like Phil78 provide counterevidence, Wikipedia provides a tiny bit of support for my assertion:

With the evolution of hairless skin, abundant sweat glands, and skin rich in melanin, early humans could walk, run, and forage for food for long periods of time under the hot sun without brain damage due to overheating, giving them an evolutionary advantage over other species.[7] By 1.2 million years ago, around the time of Homo ergaster, archaic humans (including the ancestors of Homo sapiens) had exactly the same receptor protein as modern sub-Saharan Africans.[16]
