2. Jane Goodall
Jane Goodall is a British primatologist, known as the world’s foremost expert on chimpanzees. She has studied social and family interactions with wild chimps for over 55 years. Her revolutionary work showed that chimpanzees, and not only humans, can learn to make and use tools. She also made pioneering observations on the violent nature of chimpanzees, finding some to hunt and eat smaller monkeys.
Founder of the Jane Goodall Institute, Goodall is a tireless advocate for conservation, biodiversity and other environmental causes.Jane Goodall, the world’s foremost authority on chimpanzees, communicates with chimpanzee Nana, 06 June 2004 at the zoo of Magdeburg (eastern Germany).
