Chimpanzee communities can adopt their own local customs and maintain their own "multiple-tradition cultures," an international team of researchers has found. The study demonstrates that chimpanzees, like people, can acquire new traditions, and spread those new "cultural practices" to other groups.
Led by primatologists at the University of St. Andrews, the researchers introduced novel forms of behavior into different chimpanzee communities to test the theory that behaviors such as foraging habits are passed on by observation and learning.
They found that, after a period of time, unique cultures developed within different communities and new traditions spread from one group to another.
Once chimps have learned a method of doing something, such as a unique way of finding food or using a tool, they have the ability to pass on this novel tradition to members of their own group as well as to neighboring communities, the scientists discovered.
