During the period of juvenile, from 6 to 9 years old, chimpanzees behave independently but still close to their mother. The mother chimp teaches their offspring how to survive in the wild. Jane Goodall did the research on wild chimpanzee at Gombe, Tanzania. She found out mother chimpanzees will teach their kids how to use and make tools so that baby chimpanzees can learn living skills. For instance, when arriving at the termite nests, the mother chimp carries the useful tool and uses the strategy to grab termite. Therefore, offspring will mimic their mother’s behavior and learn the skill. On the other hand, the mother chimp will teach young chimps how to act in social system. Chimpanzees learn the skill by watching their mother chimp commutes with other chimpanzees. It is important to build up the relationship with the group for safety and support. For example, if the mother chimpanzee is dead, the older siblings or other females in the group will take care of baby chimp. This kind of interaction represents that chimps are the social animals, living in the community of the big family.
