Scientists studying chimpanzees in Uganda have discovered that tribal conflict and lethal warfare are not exclusively human traits, suggesting that the tendency for organized violence is deeply embedded in our shared evolutionary DNA.
While common wisdom often suggests that religion and the pursuit of natural resources are the primary drivers of human conflict, new scientific insights into the natural world suggest that our penchant for warfare may be etched far deeper into our biological makeup.
Researchers studying a decade-long civil war among a chimpanzee population in Uganda’s Kibale National Park have concluded that the urge to divide into enemy tribes and engage in lethal violence exists independently of human-made ideologies or political propaganda. This discovery, detailed in the journal Science under the title Lethal conflict after group fission in wild chimpanzees, highlights a brutal reality: the propensity for organized group violence may be an evolutionary inheritance we share with our closest primate relatives, dating back millions of years. The study focuses on the Ngogo community, a group of approximately 200 chimpanzees that began to experience internal division around 2015. Following the deaths of several stabilizing elders, the troop split into two distinct factions: the dominant Central tribe and the splinter group known as the Westerners. Unlike previous observations of primate aggression, which were typically linked to immediate survival needs like mating rights or food scarcity, this conflict represents a prolonged, systematic campaign of violence. By 2024, at least seven adults and 17 infants had been confirmed killed by rival gangs, with at least four additional casualties reported since. Anthropologists like Aaron Sandel have noted that these interactions involve tactical planning, raids, and high levels of brutality, effectively mirroring the mechanics of human warfare despite the complete absence of cultural or political catalysts. The documentation of this conflict was facilitated by three decades of intensive study, including footage captured by filmmakers for the Netflix series Chimp Empire. The narrative of the conflict is punctuated by heartbreaking individual stories, such as the death of a gentle chimp named Pork Pie. An amiable, non-aggressive member of the Central clan, Pork Pie was isolated from his peers while foraging and was subsequently mauled to death by Westerner raiders. For the researchers and film crews observing these events, the experience was profoundly traumatic. They witnessed not only the tactical nature of the chimpanzees' aggression—which included sentry patrols and coordinated ambushes—but also the unsettling realization that such violence is not an aberration of a civilized society, but a manifestation of a primal impulse. These observations suggest that the capacity for tribal warfare is not merely a social construction but a biological shadow, indicating that the desire to dehumanize and destroy the 'other' may be a fundamental, if devastating, component of our evolutionary history
