- A permanent fission occurred in the largest-known group of wild chimpanzees, transitioning from cohesion to polarization by 2015 and forming two distinct groups by 2018.
- Over seven years following the split, one group conducted 24 attacks on the other, killing at least seven mature males and 17 infants.
- This event demonstrates that group identities can shift and escalate into lethal hostility in chimpanzees, even without cultural markers often associated with human warfare, offering insights into human civil war dynamics.
