Final answer:
Jane Goodall, Birutė Galdikas, and Dian Fossey were all primatologists who made significant contributions to the study of great apes and conservation biology.
Step-by-step explanation:
Jane Goodall, Birutė Galdikas, and Dian Fossey are renowned for their pioneering work in primatology. They each studied one of the three great apes in their natural habitats: Goodall researched chimpanzees in Tanzania, Galdikas studied orangutans in Borneo, and Fossey's work focused on gorillas in Rwanda. These three women made monumental contributions to our understanding of great apes, their behavior, and the need for conservation which had a profound impact on conservation biology and animal behavior studies. Jane Goodall is known for her groundbreaking research on chimpanzees, Birute Galdikas studied orangutans, and Dian Fossey focused on mountain gorillas. They all conducted extensive fieldwork, observed primates in their natural habitats, and advocated for their protection.
