Jane Goodall was making observations on chimpanzees.
<u>Explanation: </u>
Jane Goodall spent years with the chimpanzees of Gombe. It all started when she found a chimp who was hungry and wonderfully used a twig of the branch to take the termites of the tree and feed on it. Goodall was fascinating to see a chimp think and behave like a human.
