Oh yeah, the ability to digest lactose....that one is a certainty.....That is why white skin developed
"First, the scientists confirmed an earlier report that the hunter-gatherers in Europe could not digest the sugars in milk 8000 years ago, according to a poster. They also noted an interesting twist: The first farmers also couldn’t digest milk. The farmers who came from the Near East about 7800 years ago and the Yamnaya pastoralists who came from the steppes 4800 years ago lacked the version of the LCT gene that allows adults to digest sugars in milk. It wasn’t until about 4300 years ago that lactose tolerance swept through Europe."
What, did they find some 8000 year old teenage diary that said "Today, I drank milk and turned white". Gimme a break.
