Now I'm worried that this will lend another weapon to the 'autistic = Neanderthal genes' hypothesis, in that Neanderthals weren't farmers, and didn't consume bovine milk or wheat...
There are people who seriously believe that Asperger's is just having Neanderthal DNA? Wow, I never knew.
Also, when Neanderthals were around, Humans had not developed agriculture or husbandry either.
