| Outline of Final Research Achievements |
The research of individual differences in animal behavior helps us to understand the evolution of human personality. The Japanese macaque (Macaca fuscata) is categorized as one of the most despotic species in the genus Macaca. Dominant monkeys can unilaterally attack subordinates without counter-aggression and monopolize provisions. In this study, I conducted the food provisioning experiments and cooperative problem solving task in the free-ranging groups of Japanese macaques. The Katsuyama and Shoodoshima groups showed despotic social structures. On the other hand, the monkeys in Awajishima groups were highly tolerant and enable to solve the cooperative food-retrieval tasks. I found that the differences between the tolerance levels of the three groups are related to polymorphisms of the candidate genes for aggressive behavior. These results indicated that individual differences in tolerance of Japanese macaques may reflect genetic background.
