| Abstract: | Intensive longitudinal behavior observations of male chimpanzees in stable mixed-sex social groups in a semi-natural environment were analyzed by state of development as defined by dental, growth and hormonal signals. Initial increase of sexual behaviors preceded adolescent hormonal changes. Peak prevalence of sexual behaviors coincided with the adolescent period. This period is also characterized by peak activity level and feeding. The major increase in aggression and stabilization of submissive behavior at adult level occurred concomitant with achievement of adult hormone levels and body size, and these were accompanied by increase of grooming affiliative behaviors. |
