Chimpanzee 'civil war' observed in Uganda

The decades-long study reveals that the violence is driven by territorial disputes and shifts in social hierarchy.

Scientists are stunned by the level of coordination and aggression displayed by the primates, which mirrors human patterns of warfare.

The conflict has resulted in multiple fatalities and has fundamentally altered the social structure of the forest community.

The findings are providing new insights into the evolutionary origins of lethal group violence and the fragility of social bonds in the animal kingdom.
