Jane Goodall couldn’t believe her eyes. It was November 1960, and she was in a forest in Tanzania, a country on the east coast of Africa. The 26-year-old Goodall had arrived in what is now Gombe National Park four months earlier. She was there to study wild chimpanzees—which no one had ever done before.
Goodall watched as a chimp she had named David Greybeard stripped the leaves from a stalk of grass and stuck it into a mound where termites lived. He then pulled the stalk from the hole and ate the termites covering it.
“At that time, science believed that humans, and only humans, used and made tools,” Goodall, now 88, explains.
Goodall’s discovery was a major step in changing the way we think about our closest relatives in the animal kingdom. More than 60 years later, Goodall is one of the world’s most famous conservationists. She’s working to make the planet a better place not just for chimps but for all living things.
