The study suggests that the brains of our hunter-gatherer ancestors were perfectly adapted to life on the African savannah, where the population would have been scattered, with people living in groups of around 150. Social interaction would have been extremely important in order to survive, especially in terms of co-operation and finding a mate, but space would have been crucial as well.
这一研究表明我们狩猎祖先的大脑完全适应了非洲大草原的生活,那里的人群分散,大约150个人生活在一个群体中。为了生存,社交至关重要,尤其是在合作和寻找配偶方面,但空间也同样重要。
