“.....The mating of a female Neanderthal with a modern human male was unlikely because she would find him gracile and he would find her robust.....”
Ever spent much time in a trailer park? This kind of thing happens every day.
As an acquaintance of mine said, concerning a mutual friend, who was skinny and dating a “robust” woman (whom he later married),
“If she don’ weigh more ‘n’ he do, he don’ wan’ ‘er!”
I’ve always wondered how the cavemen could be reconciled on a time scale with Biblical teachings of Adam & Eve being the origination of humans?
