Now, Andrew Whiten from the University of St Andrews has published the first evidence that groups of chimpanzees can pick up new traditions from each other. In an experimental game of Chinese whispers, he seeded new behaviours in one group and saw that they readily spread to others.Whiten ran an experiment in which he taught some chimps, but not others, how to extract food from trick boxes. He then put those chimps in a position to be observed by other chimps who couldn't interact directly with them. And this is what he discovered:
Whiten found that the techniques were accurately and quickly transmitted between the different chimpanzee groups. His experiment clearly shows that chimps have an immense capacity for learning new behaviours from their peers. They do this accurately and different groups can acquire and maintain several varied cultural traditions.Deary, deary me. That sounds an awful lot like what happens in traditional human societies, don't it just? That's going to get the creationists' knickers in quite a twist.
In light of this evidence, the regional behaviour patterns seen in chimp groups across Africa are, without a doubt, the result of cultural transmission. In the wild, rival groups are often hostile towards each other and it is unlikely that chimps sit down in jungle conferences to share new ideas. But females do move between groups and Whiten believes that they carry new cultural traditions with them.
I know some people get really steamed over the idea that we're not on some high pinnacle above the mere beasts, but I find things like this comforting. I feel like humanity is less alone in the universe. Not to mention, no needing to worry about how, if humans are supposed to be teh awesome, we're often so bloody, bloody ridiculous. We're just natural, no better and no worse than the rest of our cousins, but with the responsibility to at least try to use the brains evolution gave us to become better creatures.
