Scientists have discovered that chimpanzees have developed different ways of screaming during fighting. The findings, led by psychologists at the University of St Andrews, suggest that the subtle differences in vocalisations may have been developed to provide important clues for nearby allies.
When we describe someone 'aping' someone else, it implies they are mindlessly copying them. This does apes a disservice, according to a recent study by scientists from the University of St Andrews. In fact, it's the young members of our own species who are more likely to 'ape' their elders without too much thought.

Experts in evolution and animal behaviour will gather next week to debate whether chimpanzee 'culture' is any less real than human culture - the outcome of which may lead to a rethink of the human evolution process.

Chimpanzees display some of the same cultural diversity as people, according to two of the world's leading primate experts.
Everything from addiction to chimpanzee behaviour will come under the microscope at the University of St Andrews this month (Saturday 17 March 2001).
A primate expert has developed an innovative technique which is providing the first clear evidence that children and chimpanzees learn the traditions of the community they live in by similar processes of imitation.
