Human beings do not like to think of themselves as animals. It is thus with decidedly mixed feelings that we regard the frequent reports that activities once thought to be uniquely human are also performed by other species: chimpanzees who make and use tools, parrots who use language, ants who teach. Is there anything left?
-
Humans structure their collaborative actions with joint goals and shared commitments.

Another subtle but crucial difference can be seen in communication. The great apes — chimpanzees, bonobos, gorillas and orangutans — communicate almost exclusively for the purpose of getting others to do what they want. Human infants, in addition, gesture and talk in order to share information with others — they want to be helpful. They also share their emotions and attitudes freely — as when an infant points to a passing bird for its mother and squeals with glee. This unprompted sharing of information and attitudes can be seen as a forerunner of adult gossip, which ensures that members of a group can pool their knowledge and know who is or is not behaving cooperatively. The free sharing of information also creates the possibility of pedagogy — in which adults impart information by telling and showing, and children trust and use this information with confidence. Our nearest primate relatives do not teach and learn in this manner.

Finally, human infants, but not chimpanzees, put their heads together in pretense

create roles

Human beings have evolved to coordinate complex activities, to gossip and to playact together. It is because they are adapted for such cultural activities — and not because of their cleverness as individuals — that human beings are able to do so many exceptionally complex and impressive things.
-
Of course, humans beings are not cooperating angels; they also put their heads together to do all kinds of heinous deeds. But such deeds are not usually done to those inside “the group.” Recent evolutionary models have demonstrated what politicians have long known: the best way to get people to collaborate and to think like a group is to identify an enemy and charge that “they” threaten “us.”
