" Humans have evolved levels of cooperation that are unprecedented among primate species. You can see it even in babies. Say you are playing with a baby and begin to put the toys in a box. If you point to one of the toys, the baby is likely to put it in the box (Liebal et al. 2009)... Human babies are more likely than other primates to follow another’s pointing or gaze. Thus, even before adults have socialized them, babies show tendencies to be in sync with the social behavior of others, to infer others’ intentions to cooperate, and to prefer cooperation in others.
