20th-century British zoologists

Dame Valerie Jane Morris Goodall was an English primatologist and anthropologist. Regarded as a pioneer in primate ethology, and described by many publications as "the world's preeminent chimpanzee expert", she was best known for more than six decades of field research on the social and family life of wild chimpanzees in the Kasakela chimpanzee community at Gombe Stream National Park in Tanzania. Beginning in 1960, under the mentorship of the palaeontologist Louis Leakey, Goodall's research demonstrated that chimpanzees share many key traits with humans, such as using tools, having complex emotions, forming lasting social bonds, engaging in organised warfare, and passing on knowledge across generations, which redefined the traditional view that humans are uniquely different from other animals.
