Much of the information we have today about chimpanzees(黑猩猩)comes from the research of Jane Goodall.

From an early age, Jane was interested in animals and animal stories. At the age of 10, she was talking about going to Africa to live among the animals there. At that time, in the early 1940s, this was a radical(激进的)idea because women did not go to Africa by themselves.

As a young woman, Jane finished school in London and then worked for filmmaker for a while. When a school friend invited her to visit Kenya, she worked as a waitress until she had earned(挣)the fare to travel there by boat. She was 23 years old at that time.

Once in Kenya, she met Dr. Louis Leakey, a famous paleontologist(古生物学家). He was impressed with her knowledge of Africa and its wildlife and hired her to help him and his wife on a fossil-hunting tour. Dr. Leakey soon realized that Jane was the perfect person to complete a study he had been planning for some time. she expressed her interest in the idea of studying animals by living in the wild with them, rather than studying dead animals like fossils(化石).
