Chimps in Uganda start a civil war lasting years after splitting into rival factions

Scientists found sustained chimp violence eerily like human wars

A new investigation from Uganda’s Kibale National Park reports the first clearly documented civil war among chimpanzees. Since 2015, the Ngogo group has fractured into rival factions, and violence has persisted in patterns rarely seen outside human conflicts. The findings suggest complex, long-running political conflict may exist in other primates too.
