Is skin tone an accurate indicator of where your direct ancestors evolved? In particular is it safe to assume that a fair skin means that your pre- agricultural revolution ancestors evolved in a far northern latitude with low levels of sunlight quantity and intensity? Also, were paleolithic humans in cold areas selected for ability to get fat? Whilst I am aware of the discussion about the "fat gene",can you confirm that in colder climates ( equal chicago today ) only humans able to quickly gain weight in a short annual ( fall ) period of plenty could have survived the severe winter/early spring?
Re: Are fair skin or fat deposits good indicators of ancestral lineage in very cold regions?
