- To learn as much as possible, Goodall carefully observed the chimps. She interacted with them. When chimps climbed trees, so
did Goodall. She also ate with them. Goodall's observations taught scientists many new things about chimpanzees. Chimps have
their own language that includes different sounds, and they sometimes communicate through touch. One of the most stunning
and important observations Goodall made was that chimpanzees use tools in the same way humans do. Goodall saw chimps take
the leaves off sticks and use the sticks to get food. This astonished the scientific community because, before this discovery,
people believed that no animals used tools.
