Fiorella, eagerly following the newest Neanderthal info, is interested to learn that, according to DNA studies, non-African homo sapiens show evidence of Neanderthal DNA, but Neanderthals show no evidence of our DNA. The obvious conclusion is that Neanderthal men could sire children on Cro-Magnon women, but Cro-Magnon men could not mate productively with Neanderthal women.
All of which ties in with a theory Fio has held for years, that the females of the species are the key. Neanderthal women's pelvises were built differently than those of homo sapiens, they carried their babies in utero longer, and their children had more developed bone structures at birth--all of which could have negatively affected them giving birth to sapiens babies.
And Husband has chimed in with the theory that children born to Neanderthal mothers and Cro Magnon fathers could have been mules, unable to breed.
Scientific world, do you hear us?
