In a groundbreaking study published in the journal *Science*, researchers have documented the first instance of organized lethal conflict among chimpanzees, specifically within the Ngogo group in Kibale National Park, Uganda. Once a cohesive community, the group began to fracture on June 24, 2015, leading to the emergence of two polarized factions. Over the years, the western faction launched coordinated attacks against the central group, resulting in the deaths of several adult male chimps and severe injuries to an alpha male by 2017. By 2021, the conflict escalated to include frequent infanticide, with scientists recording seven attacks on adult males and 17 on infants from 2018 to 2024. This unprecedented behavior highlights the complex social dynamics of chimpanzees and raises questions about their social structures and conflict resolution.
