Chimpanzees have been taught to use sign language. There have been studies and experiments conducted with chimpanzees, such as the famous case of Washoe, who was able to learn and use sign language. While there have been limited studies with other primates such as macaques, baboons, lemurs, and vervets, they have not been shown to use sign language to the same extent as chimpanzees.
