 "The cooperative nature of human communication and the cooperative structure of human social interaction and culture are closely related. Early forms of communication were most likely gestural in nature, including pointing and pantomiming. The cooperative nature of these gestures differs qualitatively from other primate communication, which is primarily requesting to fill immediate needs. In contrast, cooperative communication requires socio-cognitive skills of shared intentionality. While chimpanzees, with whom we share a common ancestor, do have and understand individual intentionality, most do not have the skills of shared intentionality, such as joint goals and joint attention that are necessary for cooperative communication."
