Leakey, Richard :: essays research papers fc

Richard Leakey- gentleman habilis Richard Leakey was born December 19, 1944 in Nairobi, Kenya. His parents were the esteemed anthropologists Louis and Mary Leakey. Richard first became a tour guide in Kenya, but changed his mind when he institute an extinct human jaw. He then schooled himself by completing a two-year secondary commandment program in six months. From 1967-77 he and his co-workers dug up more or less 400 fossils, that accounted for 230 individuals. The most important discovery was an almost jazz skull found in 1977, which Richard believe to be a new species called gay habilis. Richard Leakeys accomplishments are discovering the crania of genus Australopithecus boisei in 1969 with the archaeologist Glynn Isaac on the East shores of Lake Turkana, Homo habilis in 1972, and Homo erectus in1975. He was appointed administrative director in 1968 of the National Museum of Kenya, and in director 1974. Since 1989 he has been director of the Wildlife and Conservation focus Service, Kenya. His publications include Origins in 1977 and The Making of Mankind in 1981, both with Roger Lewin. Australopithecus africanus inhabited the earth roughly 3 - 1.6 million years ago. The attribute difference between the Ausrtalopithicus afarenis and africanus is the height and mindset capacity. The height of the africanus is 1.4 m and the brain capacity is approximately 400 - 600 cc. Smaller incisor teeth and a pretty flatter face are also noted. The afarensis has a height of 1.2 m and a cranial capacity of 380 - 450 cc. Sticks, and stones were most likely used to see food by the Australopithecus africanus. Homo habilis (also known as " practised man") is theorized to have lived with Australopithecus africanus. Homo habilis was known as deft man because he used primative stone tools. The flat face and heavy(p) molars of the Homo habilis resemble the Australopithecus lineage. The brain size of the Homo habilis is near 700 cc which is larger than the Austr alopithecus). The "apelike" body structure with long implements of war and a small body was a characteristic of the Homo habilis. youthful discoveries, such as from Lake Turkana, of better-preserved fossils have revealed new insights on early Homo in the Plio-Pleistocene. Of this new habilis material, the most amazing is a nearly complete cranium discovered in 1972 at East Lake Turakana. This individual, with a cranial capacity if 775 cm3, is clearly outside the known range for Australopithecines and it overlaps the lower edge for Homo.
