Contribution of Leakey family to our increased understanding of human evolution.

bloody shame 1959 breakthrough of genus genus Zinjanthropus brainpan at Olduvai Started modern light of paleoanthropology (Study of Human Origins) Louis and Mary Leakey open fossils in Tanzania and Kenya that indicated mans evolution began in East Africa 2 billion age ago, unlike to begin with than was believed at the quantify of the discovery. in Kenya in 1947, Mary Leakey attain the skull of Proconsul africanus, an ape-like ancestor of both apes and prehistoric man that ived ab proscribed(p) 25 million eld ago. 1978 she made her about authorised discovery: footprints frozen for 3.5 million years in volcanic bumble that demonstrated that premature hominians walked upright much earlier than antecedently thought. she effect fossilized parts of the upper teething and skull of a hominid no one had recorded before, dilapidate out of an area beneficial Bed I. In the following common chord weeks the Leakeys found more than 400 pieces to plant an almost carry out skull. It was not too change from remains found in South Africa by Raymond pass in 1924 and by Robert drag out up in 1936. (Those beats had not been accurately dated because of the bearing they were found and the lack of geological dating technology.) But the Leakeys thought their find antithetical enough to install a new kinfolk of hominids, and called it Zinjanthropus boisei. They suggested that it lived 1.75 million years agoIn 1960, Mary Leakey and male child Jonathan found another, smaller lick of hominid at Olduvai that they believed was different and more advanced. They called it Homo habilis (handy serviceman) because it appeared to be the graduation exercise human to use tools. The designation of these two new groups embossed a great deal of controversy. Zinjanthropus has since been put by most scientists into the Australopithecine genus, which the South African finds also choke to, though in different species. Homo...
