When young, orphaned chimps first come to the sanctuary, they are given lots of affection and attention to compensate for the loss of their mothers. Jane Goodall, 64, who spent three decades studying chimpanzees, now advocates for animal rights and raises money for chimpanzee sanctuaries and conservation. (AP Photo/Jean-Marc Bouju)
