“So beer gogles may be at work, or it is more complicated than that, if these genetic markers prove out.”
Does PC still allow one to whisper that perhaps the genes got into our pool through Neanderthal men raping Homo Sapiens women?
And not for any PC reasons either. A Neanderthal man/Sapiens woman cross would likely have a very large head in comparison to a pure Sapiens baby. Chances of the child being delivered alive and mother and child living would be quite small.
A Neanderthal woman/Sapiens man cross would likely have a smaller head then a pure Neanderthal baby would be so the mother and child would have had a greater chance of living.
PC or not, I agree, that may have happened. But it may have been the other way around. Beer goggles could make Neanderthal gals cute. Lots and lots of beer.
