| Outline of Final Research Achievements |
To elucidate the evolution of the cooperative breeding social system in human, we conducted a comparative study of human and nonhuman primates. 1) Observation of interactions between immatures (infants and juveniles) and non-mothers among gorillas, chimpanzees, and Japanese macaques; 2) Experimental study on responses to mother and non-mother by human infants; 3) Observation of social interactions between human juveniles and non-mothers in natural conditions.
In great apes and macaques, immatures engage in affiliative interaction with nonmothers from their early developmental stage. However, they remain responsive to direct solicitation by non-mother partners, except when the partner are also immatures. In contrast, human immatures are sensitive to the behaviors by non-mother adults as well as immatures. This difference between human and nonhuman primates is thought to be related to the differences in prosociality among them.
