So says Danny Vendramini, a writer with whose credentials are hard for me to find after a a bit of searching. A bio pages says "Australian born, Danny Vendramini had successful careers as a theater and film director and scriptwriter before turning to evolutionary biology". Find me ANYBODY with serious background in the biological sciences who supports Vendramini's hypothesis, and maybe I'll pay attention.
Reconstructions by people with actual science backgrounds have Neanderthals looking not too different from us. Give one a shave, shower, and modern clothes and you would probably walk pass him on the street without thinking him that unusual.
What is it they say, you can lead a donkey to water.....
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.
