Final answer:
Jane Goodall, Dian Fossey, and Birutė Galdikas are primatologists who studied great apes and are collectively known as Leakey's Angels, a group supported by Louis Leakey.
Step-by-step explanation:
Jane Goodall, Dian Fossey, and Birutė Galdikas are renowned primatologists and researchers noted for their groundbreaking work studying great apes in their natural habitats. They are famously referred to as Leakey's Angels, named after the paleoanthropologist Louis Leakey who encouraged and supported each of their research endeavors. Goodall is known for her extensive study of chimpanzee behavior in Tanzania, Fossey for her work on gorillas in Rwanda, and Galdikas for her research on orangutans in Borneo. Each of their studies provided a deeper understanding of these primates, contributing significantly to the field of primatology and influencing the way humans understand their connection to other species.
