What kind of design did Jane Goodball use?

Jane Goodall is known for her pioneering field research and observational study design in primatology, particularly her work with chimpanzees in Tanzania's Gombe Stream National Park. She employed a longitudinal, naturalistic approach, immersing herself in the chimpanzees' habitat to observe their behaviors over time without direct interference. This design allowed her to gather detailed insights into their social structures, tool use, and emotional expressions, fundamentally changing our understanding of primates and their similarities to humans.
