   animal that can pass memory between generations, that is, create culture.

   But I recently read a story about two monkey colonies on different sides
   of a river. One of those colonies had developed more advanced ways of
   gathering food than the other and this knowledge was passed on from mother
   to child. Apparently, amongst monkeys it???s not exclusively nature; there
   is also nurture and thus culture.
