People make assumptions about how psychology works that could easily be debunked by studying chimpanzees, bonobos and other kinds of species. For example, the chimpanzee is a dulce when they're 16. They learn a lot of things in their lifetime before they are adults. And we know that there's a lot of cultural habits that they have. So if you look at the other primates, you see also culture. If you look at humans, you see more culture than biology.
