Final answer:
Jane Goodall's study of chimpanzees in the jungle exemplifies a field study, as it involved observing chimpanzees in their natural environment to understand their behavior and social interactions.
Step-by-step explanation:
Jane Goodall's study of chimpanzees in the jungle was an example of a field study. This type of research is conducted in the natural environment of the organisms being studied, allowing researchers to observe their behavior in their natural habitat without manipulation. Goodall's work is renowned for its contributions to primatology and our understanding of chimpanzee behavior, tool use, and social structures. Her approach involved making detailed observations without altering the chimpanzees' environment or actions, thereby maintaining the natural context of their lives. This is crucial for understanding behavior and social interactions, which can vary dramatically in different populations, as seen in the chimpanzees of Gombe National Park compared to those in Fongoli, Senegal.
