The name Jane Goodall is synonymous with chimpanzees. Having devoted her life to observing these animals in their native African homes, she has gained a plethora of information related to these primates. Ironically, Goodall was not always an animal behavioral analyst. But upon completing secretarial school she began working with well-known paleontologist, Louis Leakey, and was given her first assignment to study apes and chimps in Africa. While Dr. Leakey asserted that ancient apes were the descendants of chimps and humans, Goodall did not concur. Her research contradicted Leakey’s and he advised her to pursue her ideas. From there, Jane began to exclusively study chimpanzees and developed an overwhelming desire to spend her time in the jungles learning about these intriguing creatures.Which of the following accurately compares Dr. Leakey to Jane Goodall?
