She found that they hunted monkeys, baboon infants, bushpig, bushbuck, and other small mammals. Hunting is undertaken by males and always in groups. Cannibalism took place on a number of occasions and the meat, as at other times, shared within the group. Because of her prolonged observation Goodall has been able to document the social development of the individual in the community as well as the histories of a number of families. Males establish a dominance hierarchy and protect the group, while females remain with their mothers until they reach sexual maturity at about the age of ten.
Young males leave a few years earlier to establish their place in the male hierarchy.
Sibling and maternal ties, however, remain strong. In more recent years Goodall has campaigned vigorously for the conservation of chimpanzees in the wild and for a less barbarous confinement of the many held in research institutions and zoos. To this end she has set up the Jane Goodall Institute for Research Education and Conservation with centers in America, Canada, and Britain. The Penguin Biographical Dictionary of Women 2.
