All chimpanzees, including this young female, have culture.
Chimpanzees living in different colonies have invented 8 effective -- albeit sometimes messy -- ways of opening a hard-peeled fruit that is a delicacy in the chimp world, a new study has found.
The study, published in the latest issue of Animal Cognition, supports the idea that chimpanzees have culture. Just as human cultures are associated with unique ways of preparing food, chimpanzees can now be associated with unique methods of preparing their edibles. In this case, the food is the green monkey orange.
"Cultural behaviors are those that are established within a social group, are passed on through social learning (learning through observing others)," lead author Bruce Rawlings, a University of Portsmouth comparative and evolutionary psychologist, told Discovery News. "For many decades, humans were thought to be unique in their ability for culture...A growing body of research has begun to challenge the idea of human exclusivity for culture."
