A closer look
Renowned primatologist Jane Goodall was deeply disturbed when a single chimpanzee community split into two rival factions and engaged in a systematic four-year war. Between 1974 and 1978 in Tanzania, the northern Kasakela chimpanzees launched coordinated, tactical strikes against the southern Kahama group, deliberately eliminating the rival males one by one. The conflict forever shattered the romanticized scientific notion that organized warfare was a strictly human behavior.
