Chimpanzees live in complex social groups called communities, which can consist of 20 to over 100 individuals. These communities are often led by a dominant male known as the alpha male, who maintains his position through strength, intelligence, and social skills. Relationships within the group are crucial, and chimpanzees form strong bonds through grooming and cooperation. Within the community, there are different social hierarchies, including subordinate males and females. Female chimpanzees typically leave their birth community to join another, while males usually stay. This dynamic helps maintain genetic diversity and social stability within the group.
