哈佛大学的一位人类学家提出，用火做饭可以追溯到近200万年前，这可以解释人类的一些特征，比如大脑大，牙齿小。

A Harvard anthropologist has proposed that using fire to cook food could be dated back to almost two million years and that it could explain hominid features like having a large brain and small teeth.

记得你是一位人类学家，而非一位法官或决策者。

Remember that you are an anthropologist, not a judge or policy maker.
