Jane Goodall has done decades of groundbreaking research on the chimpanzees of Gombe National Park in Tanzania. This is her account of her work there over thirty years, starting when it was still scientific heresy to describe animals as having thoughts and emotions--even animals so obviously close to us in evolutionary terms as chimpanzees. Goodall didn't have a degree at all, much less in ethology, when Louis Leakey recruited her to study chimpanzees, so she described what she saw in the chimpanzees' behavior. When Leakey arranged funding and sent her to Cambridge University in 1962 to get a PhD in ethology, Goodall discovered the narrow view of the scientific establishment. In order to get her scientific work published, she pushed back where she could and compromised where she had to, and gradually had an impact on the silly practice of talking about higher mammals as inanimate objects.
