When Jane Goodall first observed wild chimpanzees hunting and eating meat nearly 40 years ago, skeptics suggested that their behavior was aberrant and that the amount of meat eaten was trivial. Today, we know that chimpanzees everywhere eat mainly fruit, but are also predators in their forest ecosystems. In some sites the quantity of meat eaten by a chimpanzee community may approach one ton annually. Recently revealed aspects of predation by chimpanzees, such as its frequency and the use of meat as a political and reproductive tool, have important implications for research on the origins of human behavior. These findings come at a time when many anthropologists argue for scavenging rather than hunting as a way of life for early human ancestors. Research into the hunting ecology of wild chimpanzees may therefore shed new light on the current debate about the origins of human behavior.
