Humans pride themselves on having extensive and diverse cultures. However, cultures can also be observed in animals. The research presented in this video aims at understanding the cultures of wild chimpanzee populations in several African countries and how they differ from each other. As chimpanzees avoid human contact, CHRISTOPHE BOESCH explains, the research team conducted the study by setting up camera traps to catch chimpanzee behavior on video. Forty locations were carefully selected to make sure interesting behavioral patterns would be observable. The vast amount of video material reveals how the diversity of chimpanzee culture is still underestimated: the chimpanzee groups exhibit a surprising variety of behavior, for example in food hunting or display, which is partly shaped by their environment. Sadly, this study also indicates to what extent the habitat of chimpanzees has already been irretrievably destroyed.
