In all, data included pattern analysis of 152 killings by chimpanzees. "A key take-away from this research is that human influence does not spur increased aggression within or between chimpanzee communities."Ī team of 30 ape researchers assembled extensive data sets spanning five decades of research gathered from 18 chimpanzee communities experiencing varying degrees of human influence. Morgan has studied chimpanzees deep in the forests of Republic of Congo for 14 years. "Humans have long impacted African tropical forests and chimpanzees, and one of the long-standing questions is if human disturbance is an underlying factor causing the lethal aggression observed," explained co-author David Morgan, PhD, research fellow with the Lester E Fisher Center for the Study and Conservation of Apes at Lincoln Park Zoo in Chicago. If we are using chimpanzees as a model for understanding human violence, we need to know what really causes chimpanzees to be violent," said University of Minnesota researcher Michael L. "This is an important question to get right. The study began as a response to a growing number of commentators claiming that chimpanzee violence was caused by human impacts. ![]() New research from an international coalition of ape researchers, published September 18 in the journal Nature, has shed new light on the subject, suggesting that human encroachment and interference is not, as previous researchers have claimed, an influential predictor of chimp-on-chimp aggression.
