Conservationist Jane Goodall, whose work revolutionized the study of primates, has died

"Jane Goodall, whose lifelong work as a primatologist helped broaden the world's understanding of animal behavior and emotions, has died, her institute said Wednesday. She was 91. Her field studies with chimpanzees not only broke barriers for women and changed the way scientists study animals, but documented emotions and personality traits within these primates that blurred the line between humans and the animal kingdom."

"She passed away due to natural causes in California during a speaking tour in the United States, according to her institute. Dr. Goodall's discoveries as an ethologist revolutionized science, and she was a tireless advocate for the protection and restoration of our natural world, the institute said in a statement on social media. Here's a look at the life of world-renowned primatologist, activist and conservationist Jane Goodall."

Jane Goodall died at 91 in California from natural causes while on a speaking tour in the United States. Her field studies of chimpanzees expanded understanding of animal behavior and emotions and broke barriers for women in science. She documented emotions and personality traits in chimpanzees, observed warfare between communities, tool use, meat-eating, altruism, and adoption of unrelated orphaned infants. She earned a Ph.D. in ethology from Cambridge in 1965 without first obtaining a bachelor's or master's degree. She named individual research subjects and became a prominent activist for protection and restoration of the natural world.
