Nearly 6,000 people came to Beasley Coliseum the evening of March 8 to hear Jane Goodall speak about chimpanzees, conservation, and her own growth from shy child to scientific celebrity. In the early 1960s, she became the first person to observe chimps using sticks to dig up termites to eat. That finding demolished the notion that tool use is a distinctively human activity and led to other studies showing that chimps have high mental abilities and a rich emotional life that includes joy, anger, grief, and embarrassment. What remains uniquely human is our complex speech and the ability to share ideas, said Goodall; no one will ever see several thousand chimps sitting still and listening to another chimp talk.
