This text focuses on the groundbreaking work of Jane Goodall in understanding animal communication, specifically with chimpanzees. It highlights how her observations challenged previous assumptions about animal intelligence and communication abilities. Goodall's studies demonstrated that chimpanzees can communicate through touch, sound, and even sign language, and that they use tools, a trait previously thought to be exclusive to humans. The text emphasizes the impact of Goodall's research on our understanding of animal behavior and communication, and how it has paved the way for further studies on animal communication in other species, such as whales and elephants.
