Both fogys - humankind erectus and homosexual habilis - were discovered in Kenya go almost Lake Turkana . Actually , these fossils are claimed to change scientific views of behavior and ontogenesis of Homo sapiens . Homo erectus is date at about 1 .55 one million million years and the fossil is anonymous . H . erectus was in all likelihood to suffer from tortuosity and only minor postmodernism damage . Anthropologists assume that H . erectus is a young crowing with oviform calvia as a moderate of sloping frontal . In posterior view the fossil is heptangular with greatest breadth and in superior view it is in tear-drop construct . Homo habilis is dated at 1 .44 million years and this fossil is likely to be the youngest among other fossils of this mintage The fossil includes the parts of palatine and zygomatic processes . The nasal sill is often missing , and palatine processes point the midline . Cusp morphology isn t absent . The molar shape of the fossil is rectangular . Scientists argued that two fossils seemed to live in the aforesaid(prenominal) areas as chimpanzees and gorillasAnthropologists were surprised having revealed that H . erectus and H habilis were likely to defend been contemporaries . Actually , the phylogenesis of Homo sapiens was viewed as a linear progression get-go from H habilis and deprivation to H . erectus , and finally to modern populace . That husking of H . erectus skull changed the ideas about the evolution of modern existence . The size of H . erectus skulls was too small to belong to a young adult but it was truth . Earlier anthropologies sight that H erectus skull was larger than they imagined . It was inferred that H erectus males were bigger than females . Anthropologies assumed that H erectus was homogeneous to H .
sapiens as life style and body shape were similar . The new discovery showed that H . erectus lifestyle was similar to that of gorillas , where males were prevailing with a harem of females Such discovery appeared a veritable surprise for scientists as they had to re-shape their ideas about evolution . So , H . erectus is less likely to be a descendant of H . habilis as it was believed earlierReferencesHopkin , Michael (2007 , August 8 .
