As a girl in England, Jane Goodall dreamed of traveling to Africa to study animals in the wild. In the summer of 1960, her dream brought her to the shores of Lake Tanganyika, to observe the wild chimpanzees at Gombe Stream. Other scientists did not believe that a 26-year-old woman could survive alone in the bush, but Jane Goodall did more than survive. Her work revolutionized the field of primatology. Over the years, she found chimpanzees engaging in activities that were once thought definitively human, such as tool-making, cooperative hunting and even warfare. Her work, the longest continuous field study of any living creature, has forced us to redefine our understanding of what it means to be human, and provided a vital insight into the evolution of our own species. Today, Jane Goodall travels the world, campaigning for the humane treatment of all animals, and empowering young people in their own efforts to preserve the environment for all living things. In this two-part podcast, recorded at South Africa's Singita Sabi Sands Game Reserve during the 2009 International Achievement Summit, Dame Jane Goodall gives an engrossing account of her lifelong study of chimpanzees in the wild.
