YouTube. YouTube. Monkeys co-operate for food. Primatologists at the Yerkes Primate Center of Emory University in Atlanta have found new evidence that capuchin monkeys (a small but large-brained South American primate) cooperate to obtain food and share the rewards of their efforts.
In the three-year study, Dr. Frans de Waal, director of Yerkes' Living Links Center, and Michelle Berger, senior laboratory assistant, modeled the natural hunting behavior of capuchin monkeys. In the wild, these primates pursue a prey as a group, but only one actually makes the capture. YouTube.
