A clip, from 1997, where Jane Goodall compares the aggressive behavior found in chimpanzees to war (see also: war thermodynamics) and human nature. |
“In the Gombe, wild chimps patrol territories of up to five to eight square miles. Regularly, small groups of males steal along the border of their range, sniffing the ground for the trace of strangers, and climbing trees to peer across neighboring territories. When an unfamiliar chimp, all except childless females, comes too close, they charge, attack, and occasionally severely injure the intruder. In one instance, an older female was attacked so severely by four males that she died five days later of her wounds. In 1970, a chimpanzee war began. A splinter group of seven males and three females with their young split off from their comrades in the north of the reserve and began a group of their own in the south. For a while individuals met at the border to solve their differences by loud calling, hurling branches and mock charges at each other. But in 1974 five males from the original Gombe community began to roam deep into the southern territory. Within three years, they attacked and murdered all of the adult males (except two who died of natural causes) and one old female—extinguishing the splinter enclave and extending their territory to the south.”
