Leakey, Louis Seymour Bazett (1903-1972)
SYNONYMS OR RELATED TERMS: L.S.B. Leakey
CATEGORY: person
DEFINITION: Kenyan-born British archaeologist and anthropologist whose brilliant career was devoted to the recovery and interpretation of the bones and tools of early man and his forebears in East Africa. His name is particularly associated with Olduvai Gorge and Homo habilis, and his work was extended and continued by his wife Mary and son Richard. As a geologist and paleontologist, he clarified the paleoclimatic scale of the Pleistocene. His intensive early Hominid research in East Africa included finds of Australopithecus boisei (Zinjanthropus) and Homo habilis, dating to c 1.75 million years ago. These discoveries proved that man was far older than had previously been believed and that human evolution was centered in Africa, rather than in Asia, as earlier discoveries had suggested. Leakey was also noted for his controversial interpretations of these archaeological finds. He was also instrumental in persuading Jane Goodall and Dian Fossey to undertake their pioneering long-term studies of chimpanzees and gorillas, respectively, in those animals' natural habitats. Leakey wrote "Adam's Ancestors" (1934; rev. ed. 1953) "Stone-Age Africa" (1936) "White African" (1937) "Olduvai Gorge" (1952) "Mau Mau and the Kikuyu" (1952) "Olduvai Gorge 1951-61" (1965) "Unveiling Man's Origins" (1969; with Jane Goodall) and "Animals of East Africa" (1969).
Leakey, Mary Douglas (1913-1996)
CATEGORY: person
DEFINITION: English-born archaeologist and paleoanthropologist who made several of the most important fossil finds subsequently interpreted and publicized by her husband, the noted anthropologist Louis Leakey. She discovered the skull of Proconsul africanus, an apelike ancestor of both apes and early humans that lived about 25,000,000 years ago. At Olduvai Gorge she found the skull of an early hominid Australopithecus boisei (Zinjanthropus). At Laetoli, she discovered several sets of footprints made in volcanic ash by early hominids who lived about 3.5 million years ago. The footprints indicated that their makers walked upright; this discovery pushed back the advent of human bipedalism to a date earlier than had previously been suspected by the scientific community. Among Mary Leakey's books were "Olduvai Gorge: My Search for Early Man" (1979) and the autobiographical "Disclosing the Past" (1984).
Leakey, Richard (1944- )
CATEGORY: person
DEFINITION: Kenyan physical anthropologist and paleontologist, son of Louis and Mary Leakey, responsible for extensive fossil finds of human ancestral forms in East Africa. His investigations suggested that relatively intelligent, tool-using ancestors of true man lived in eastern Africa as early as 3,000,000 years ago, or almost twice the time span of previous estimates. Leakey uncovered some 400 hominid fossils, making Koobi Fora the site of the richest and most varied assemblage of early human remains found to date in the world. Leakey proposed controversial interpretations of his fossil finds. In two books written with science writer Roger Lewin, "Origins" (1977) and "People of the Lake" (1978) Leakey said that about 3 million years ago three hominid forms coexisted with each other: Homo habilis Australopithecus africanus and Australopithecus boisei. Leakey contended that a relatively large-brained upright bipedal form of the species Homo lived in eastern Africa c 2.5-3.5 million years ago. He also wrote "The Making of Mankind" (1981).
