The world's largest known wild chimpanzee group — the roughly 200-member Ngogo community in Uganda's Kibale National Park — split in 2015 into two factions called Western and Central, after which the Western group launched years of lethal attacks on their former groupmates. Between 2018 and 2024, Western adults killed seven males and 17 infants from the Central group, with an additional 14 Central males disappearing under circumstances suggesting further violence. Published in the journal Science, the study shows how tensions in once-peaceful groups can escalate into deadly violence even without resource shortages or cultural divisions, with potential implications for understanding human conflict.
