他们野蛮，因为吃肉；我们温良，因为食谷。你用的是这种华语圈流行的推断吗？下面是关于欧洲人吃的基因的研究：

“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.”
