The Friends of Charles Darwin

Humans are not the only conformists in the animal kingdom. New research shows that chimpanzees also tend to imitate their peers, suggesting that the human penchant for follow-the-leader may be more deeply rooted than thought. Chimpanzees have behavioural traditions that vary between groups in the wild but, so far, direct experimental evidence of how these traditions are spread and maintained has been lacking. So Andrew Whiten of St Andrews University, UK, led a team that sought to show a chimpanzee proclivity for cultural conformity in a population of captive animals.
