A serious conflict has emerged among chimpanzees in Kibale National Park, Uganda, leading to the deaths of at least 28 individuals since 2018. Researchers observed that the once-unified group of nearly 200 chimps has split into two factions: the Western group, which has been executing planned attacks on the Central group. The decline in social cohesion is attributed to several factors, including the deaths of older chimps, the rise of a new alpha male, and disease outbreaks in 2014 and 2017. The violence escalated after a shocking incident in 2019, where a male chimp named Basie was attacked by former companions. This situation illustrates how quickly social structures can collapse among animals known for their communal living, marking only the second instance of such a conflict among chimpanzees, the first being recorded in Tanzania in the 1970s.
