Duke University assistant professor Brian Hare and colleagues study the behavior of bonobos -- apes that are genetically close to humans.

Sharing is a behavior on which day care workers and kindergarten teachers tend to offer young humans a lot of coaching. But for our ape cousins the bonobos, sharing just comes naturally.

A new study of chimpanzees living in the wild adds to evidence that our closest primate relatives have cultural differences, too.

American researchers who have been studying the rare and threatened bonobo ape will lead monitoring efforts after a group of orphan bonobos are returned to the wild in the Congo for the first time this month.

Despite enormous costs and often-tragic results, humans have waged war throughout the course of history, and continue to do so today.
