Nature | The secret of the apes

This film explores a scientific debate on the culture, or lack thereof, of great apes. Internationally acclaimed primatologist Christophe Boesch and colleague Michael Tomasello investigate the behavior of chimpanzees in the wild and in captivity to assess their behaviors and begin to understand why certain groups develop skills differently than others. A conflict exists in the scientific community with some scientists believing that apes certainly have established cultures, while other scientists disagree and feel culture separates apes from humans. British primatologist Jane Goodall provides her own theories based on fifty years of research in the field.
