Summary

On page 102, primatologists describe two dozen behaviors that are present in some orangutan groups and absent in others. The practices are apparently learned from other group members and passed from generation to generation. Such observations give biologists richer insights into animal behavior, others say, and they might help researchers understand how human culture evolves.
