In addition Neanderthals were probably mostly blue eyed and red headed. The so called “ginger” gene found in about 40% of people of that coloration in the British Isles, or is it 40% of all or something like that. That coloration made Vitamin D formation and absorbtion from skin more effective, and thus better formation of female pelvic (birth) structure.
The “Redheads ‘Are Neanderthal’” topic that originally enticed me to FR years ago is gone (it was one of the old-style topics that got purged, I believe as part of the out of court agreement with AP) but there’s plenty more where that came from:
