Why a chimp 'civil war' shows how societies collapse
In the mid-1970s, primatologist Jane Goodall witnessed a four-year conflict amongst chimpanzees in Tanzania where they killed each other—a primate civil war. Now it's happening again in the largest known chimpanzee community, offering insights into how human societies can fall apart.
