Jane Goodall branches out
Goodall, who is set to receive the Leakey Prize, is focusing on humanitarian efforts. She says chimps in Africa can't be protected unless people's living conditions are improved. Jane Goodall's research has changed the definition of what it means to be a human. When she went to what is now Tanzania in 1960 to study the chimpanzees of Gombe, humans were thought to be the only animals capable of making and using tools. Goodall showed not only that chimps could do that, but also that they had personalities and complex social lives, could hunt for game and even engage in warfare. She is to be in San Francisco today to accept the Leakey Foundation's prestigious Leakey Prize in human evolutionary science. This week, Goodall, 74, answered questions in a phone interview.
