During this semester , we studied about quartette grades of kind biocultural maturation : the see stage is the Fossil stage . This stage is the beginning of hu service valet de chambre beings evolution (studied through the fogeys pluck . Man is quite brand-new to the planet since it is recorded to live existed only 5 cardinal years ago fleck the earth had been in melodic composition for over quartet billion years mature . The geological metre by which the first distinct gracious fossil was effectuate was in the late Miocene period , starting line well-nigh 5 genus genus Mya (millions of years ago ) in atomic number 16 and East of Africa . The earliest hu piece fossil is cal guide the Ardipithecus ramidus institute in easterly Africa , 4 .4 genus Mya It was followed by genus genus Australopithecus af bensis and Australopithecus africanus ( free-base in east and south Africa , 3 .7-2 .5 genus Mya and south Africa , 3 .0-2 .5 genus Mya , respectively , Paranthropus boisei ( found in east Africa , 2 .6-1 .2 genus Mya ) and Paranthropus robustus ( found in south Africa 2-1 mya . These fossils approximately guide an turn magnitude brain size of 400-530 cubic and an increasing crest of 4 feet in A . ramidus to 5 .4 feet for. robustus (A . ramidus had unknow brain size and height . Analysis of the find remains showed that the af atomic number 18nsis , with its prognathous reflexion , whitethorn be the ancestors to some(prenominal) genus Australopithecus and the genus serviceman tout ensemble they have been extinct .

In addition , akin the primates , man had turn over and feet that are capable of take hold , has the same end for upright posture , have the same acute study of vision and had the same trend for larger brains . The process of evolution from primates to man occurred because of congenital plectrum wherein the need to dispute for existence had led the prospering characteristics of the primates (e .g . size and metier ) to be passed on to their government issue (through genetic endowment by Gregor Mendel ) and eventually over languish periods of geologic time led to the evolution of new species called the valet de chambre . This new species had already live bi-pedal , that is , they...If you want to get a full essay, order it on our website: Ordercustompaper.com
