__Where boisei was last scene__

Australopithecus Boisei was discovered when it was extinct in 1959 by Mary Leaky in the history of paleoanthropology two million years ago. The find was justified by Louis and Mary’s that they lived in Olduvai. Olduvai has been fruitless for over 30 years. Another discovery was made by a Tokyo university group of paleoanthropologists led by Gen Suwa. Some of the remains were found in East Africa – Ethiopia, but the Boisei travelled and was spread all over Africa. Boisei was found over Olduvai, Kenya, Tanzania, Koobi Fora, west Turkan in Kenya. It was first described from a cranium recovered from Olduvai, Gorge and Tanzania. The Boisei was discovered in a dry, grassland environment. The oldest Boisei was found in Omo, Ethiopia and the youngest was found in Olduvai Gorge. The oldest skull which was found is 1.4 million years old. This was found in Knonso in Southern Ethiopia. More then 100 specimens have been found dating back 2.3 and 1.6 million years ago. The newest skull which was found was dating back from between 1.43 and 1.41 million years ago. After this they could not find any more fossils because the lineage eventually died out. People can to the conclusion that the Boisei died out because of overspecialization and the environment change. They believed that the Australopithecus Robustus and Australopithecus were very similar and have thought to descend from the Australopithecus Africanus. Every discovery that was made for the hominids group, they discovered that only one species existed in one place. This was called ‘Single species Hypothesis’. It was known that no hominid group were supposed to co exist. This was exposed when the discovery of the Boisei was found with other species. They believe that if more then one species lived in the same area, the start to act the same. Before the naming of the Boisei, fossils were found to be one of the sexually dimorphic species. Robusts being the males and Gracile being the females. Boisei fossils of both sexes were found and proved that there were co existing hominid groups. A Boisei is a different species that existed at that time. Type in the content of your page here.
