Mary Leakey :: essays research papers

Though technically defined as an archaeologist, bloody shame chose to follow a route of elicit research relating to physical anthropology. She is known mostly for the excavation of a two million-year-old fossilized human skull in 1959. She has also worked to help the world understand that the organic evolution of humans follows a principle rather than a theory.The name Leakey is synonymous in most peoples minds with the successive dramatic discoveries of fossilized hominian bones and colliery artifacts that have, over the years, pushed the origins of true man further and further back in prehistory. Less flamboyant than her husband, Louis S. B. Leakey, or her son Richard Leakey, Mary Leakey was the "unsung hero, of the clan for years, unconstipated though she was, in fact, responsible for many of the spectacular Leakey finds, including the nearly complete skull of Zinjanthropus, which was at first thought to be the missing human evolutionary link. Mrs. Leakey last received a measure of long-overdue public recognition with her discovery, in 1978, of 3.5-million-year-old fossilized hominid footprints at Laetoli in Tanzania, proving beyond a doubt that the australopithecines had walked upright. On July 17, 1959 Mary Leakey made her second major discovery. Accompanied only by her two Dalmatians, Mary Leakey set off to investigate the oldest layer at the site. As she surveyed the scene with her practiced eye, a scrap of bone protruding from the ground caught her attention. Gently brushing aside some of the deposit, she saw two large hominid odontiasis in place in an upper jaw. Mrs. Leakey raced back to camp shouting, "Ive got him Ive got him" Using camels-hair brushes and dental picks, the Leakeys gingerly uncovered a full palate and set of odontiasis by sifting through tons of eroded scree, they eventually found about 400 bone fragments, which when pieced together formed an almost complete hominid skull, later dated at 1.75 million years, of th e genus Zinjanthropus. Over the next few months, Mary Leakey found other hominid bones and 164 stone tools of twelve diametric types, including choppers, scrapers, anvils, and hammerstones.As luck would have it, a camera crew for the British television series On Safari arrived on the scene the day later on Mary Leakeys momentous find, and thus it was that "Zinj" came to international public attention. For the Leakeys, it meant worldwide recognition. Fame brought controversy, too, and it was not long before Louis Leakeys bold assertion that "Zinj" was the so-called "missing link" betwixt the primitive ape-men and Homo sapiens was proved to be incorrect.
