Chimpanzees in Uganda locked in vicious 'civil war', say researchers

Researchers have documented an eight-year-long violent 'civil war' among the Ngogo chimpanzees of Uganda's Kibale National Park, where the once-cohesive community split into Western and Central groups in 2018, resulting in at least 24 recorded killings including 17 infants. Published in the journal Science, the study suggests this intraspecies violence offers insights into the evolutionary roots of human conflict, indicating group division alone can drive lethal aggression without human-specific constructs like religion or ethnicity.
