How Jane Goodall revolutionised our knowledge of chimp behaviour

For a long time, chimpanzees were misunderstood. Then Jane Goodall came along. As a young primatologist without any formal training, she travelled to the deep jungle of Tanzania in the 1960s, where she pioneered new ways to study our closest living relatives. She soon discovered that they were much more social and intelligent than scientists had previously believed. Behavioural biologist Lisette van den Berg, explains how Goodall’s work revolutionized our understanding of chimps, and radically changed the way we think about the relationship between humans and other species.
