i saw this re-run on tv and it was about how chimpanzee's will kill members of their own clan and others, for similar reasons to humans i.e revenge or dislike, it said they even beat up female chimps.
this is different than other killings because it isn't for survival or for food, they think it's more of a social culture thing

is the article abuot it.
so that makes me think.. since chimps DNA is so close to humans, do you think violence in general is
natural behaviour for humans as well? just that in our society violence is not acceptable as say in a chimps society
