“Before the Neolithic revolution that began around 10,000 years ago, European populations were hunter-gatherers that ate animal-based diets and some seafood. But after the advent of farming in southern Europe around 8,000 years ago, European farmers switched to primarily plant-heavy diets.
The study -- the first to separate and compare adaptations that occurred before and after the Neolithic Revolution -- reveals that these dietary practices are reflected in the genes of Europeans.”
