Final answer:
The Leakey's, including Louis, Mary, and Richard Leakey, are key figures in paleoanthropology, while the Tri mates, Jane Goodall, Dian Fossey, and Birutė Galidas, are renowned for their studies on apes that deepened our understanding of primate behavior and evolution.
Step-by-step explanation:
The Leakey's are a renowned family of paleoanthropologists who have been instrumental in the study of human evolution. The most well-known members are Louis Leakey, his wife Mary Leakey, and their son Richard Leakey. Their work, along with John Napier, has helped identify and classify various hominin species, including Homo habilis. One of the key publications that details their work on H. habilis is 'A New Species of the Genus Homo from Olduvai Gorge' which established criteria for classifying the genus Homo, such as a brain size over 600 cc, a globular skull, tool use, and reduced prognathism.
The Tri mates refers to three prominent primatologists, each a protégé of Louis Leakey, who conducted extensive studies on different great ape species: Jane Goodall on chimpanzees, Dian Fossey on gorillas, and Birutė Galidas on orangutans. These studies provided profound insight into the behavior, culture, and society of these apes, significantly contributing to our knowledge of primate and human evolution.
