1959 breakthrough of genus Zinjanthropus cranium at Olduvai
Started modern intuition 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 million years ago, remote earlier than was believed at the time of the discovery.
in Kenya in 1947, Mary Leakey detect the skull of Proconsul africanus, an ape-like ancestor of both apes and prehistoric man that ived ab extinct 25 million years ago.
1978 she made her most important discovery: footprints frozen for 3.5 million years in volcanic bumble that demonstrated that early hominids walked upright much earlier than antecedently thought.
she found fossilized parts of the upper teeth and skull of a hominid no one had recorded before, eroding out of an area near Bed I. In the next common chord weeks the Leakeys found more than 400 pieces to comprise an almost carry out skull. It was not too varied from remains found in South Africa by Raymond Dart in 1924 and by Robert sweep up in 1936. (Those finds had not been accurately dated because of the way they were found and the lack of dating technology.) But the Leakeys thought their find different enough to constitute a new category of hominids, and called it Zinjanthropus boisei. They suggested that it lived 1.75 million years ago In 1960, Mary Leakey and son Jonathan found another, smaller form of hominid at Olduvai that they believed was different and more advanced. They called it Homo habilis (handy human) 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...
