Final answer:
Jane Goodall revolutionized primatological fieldwork in the 1960s through her groundbreaking observations of chimpanzees.
Step-by-step explanation:
In the 1960s, Jane Goodall revolutionized primatological fieldwork through her groundbreaking observations of chimpanzees in Tanzania. Goodall's meticulous and long-term study of chimpanzee behavior in their natural habitat challenged many prevailing beliefs about primates and their capabilities. Her discoveries, such as the use of tools by chimpanzees, transformed our understanding of primate behavior and the similarities between humans and chimpanzees. Goodall's work not only changed the structure of primatological fieldwork but also paved the way for future research in the field.
