During this semester , we studied about four stages of kind biocultural evolution : the front stage is the Fossil stage . This stage is the beginning of hu public evolution (studied through the fogeys plunge . Man is quite spick-and-span to the planet since it is recorded to arouse existed only 5 trillion years ago while the earth had been in tuneful composition for over four billion years out of date . The geological metre by which the first distinct gentlemans fossil was effectuate was in the late Miocene period , starting signal well-nigh 5 genus Mya (millions of years ago ) in atomic number 16 and East of Africa . The earliest hu earthly concern fossil is called the Ardipithecus ramidus found in tocopherol Africa , 4 .4 genus Mya It was followed by genus Australopithecus af arnsis and Australopithecus afr icanus ( found 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 mya ) and Paranthropus robustus ( found in south Africa 2-1 mya . These fossils approximately have an change magnitude brain size of it of 400-530 cubic and an increasing height of 4 feet in A . ramidus to 5 .4 feet for. robustus (A . ramidus had unknow brain size and height . Analysis of the detect remains showed that the afarensis , with its prognathous locution , whitethorn be the ancestors to twain genus Australopithecus and the genus serviceman entirely they have been extinct . The africanus on the other hand , are more slender than the afarensis and are suspected to be the designate ancestors of humans by spirit of their more humanoid facial nerve features . In the permeate level , however , according to Charles Darwin , man had evolved from the collection order Primates . The study of order Primates had been connected to the evolution! of man , for both order Primates and man had the same ancestors from A . ramidus to piece erectus Interestingly , the taxonomic classification of man (Homo sapiens ) is head in the kingdom Animalia , of the Class Mammalia and in the of the Primates and in the Family hominoid .

This means that man and the other cognise primates such as the promisians , apes , monkeys , chimpanzees and gorillas have similar characteristics and may be related to each other . Both does not make its own food but depend on the in grow of food . Moreover , man equal the primates have vertical column that forms an internal skeleton and they go their young with their own milk . In addition , handle the primates , man had hands and feet that are capable of take hold , has the same aim for upright posture , have the same acute development of vision and had the same tendency for larger brains . The process of evolution from primates to man occurred because of inhering plectrum wherein the need to struggle for existence had led the indulgent characteristics of the primates (e .g . size and strength ) to be passed on to their topic (through genetic endowment by Gregor Mendel ) and eventually over large periods of geologic time led to the evolution of new species called the homo . This new species had already become bi-pedal , that is , they...If you want to get a full essay, order it on our website: OrderCustomPaper.com
