By the late 1960s, a remote outpost in Tanzania was bustling with field assistants and students studying wild chimpanzees in Gombe National Park. This research, begun by renowned ethologist and conservationist Jane Goodall, transformed our understanding of our closest living relatives and, in turn, our own place in the world. Her early observations of chimpanzee tool use, hunting, and complex social relationships revolutionized the field of primatology. Since that time, a dedicated team has collected daily handwritten data on chimpanzee life—grouping, feeding, and ranging—on check sheets, as well as longhand narrative observations of behavior, including grooming, tool use, dominance, and mating.
