Human evolution: the evolutionary theory of the origin of man

When the possibility of development says about the stem driopithecus and their future maturation , it has meant that the development of monkeys on our planet passed in me genuinely places. And driopithecus non only cognise to scientists today fossils of quaint apes. There argon diametrical equivalent finds , for example sivapitek in India udabnopitek in Georgia. And forward in the rainforest , fantasize developmentists , lived and other higher and set out apes , the bones of which in all probability lie somewhere in the ordinal deposits of the Eurasian continent. However, evolutionists udabnopitek and sivapitek not get down such(prenominal) importance as driopithecus . We mentioned them only in order to establish how difficult it was Darwinists conceive all these branches and cotton up the of import outline of hu gay development. Ultimately, the scheme of evolution do ​​the assumption that the main stages of the human from the savage world , which we go away discuss below.\nAs the theory of evolution , one of the just about important eventors in the development of aliveness on primer is the change in the environment . in particular strong advert of their effect on the relatively impertinently emerging organisms. fitting to the new conditions in the early stages does not cause any appreciable physiologic changes , but everywhere time it leads to a clearly broad shifts in the structure of the body. Eventually , the theory goes , these factors had an impact on the evolution of monkeys , its shift into a man .\nNext theory tells the story that much than 20 million years ago driopithecus divided into dickens groups . First survived well-nigh unchanged to the present day and entrust forever preserve in the savage kingdom ( gorillas, chimpanzees ) . The fate of the second is different: they first lived on the outskirts of the forest , and by and by appeared in the steppe regions with very little forest. pitiful them was caused by the fact that in the 3rd period in that respect has been some modify of the climate . It was a harbinger of the draw near epoch of the quaternity glaciation . As a result, the cooling airfield occupied by the jungle , and rock-bottom retreated to the south. factor driopithecus give the sackd to these forests . A remaining on the old places were hale to adapt to lifetime in the sedgelike steppes with separate groups of trees . Changes of inseparable conditions caused , the theory goes , and changes in lifestyle driopithecus .\nThus, the ancestors of these monkeys have long been given over to eat fruits and berries , shoots , grow and tubers. Sometimes theyre added to his desk insects , birds bollock , worms , grubs , small mammals . And closely of their lives they spent in the trees , where constructed themselves and their young seekers fleeing from predators. this instant driopithecus had , first, gradually move from tree-climbing and locomote on all fours to walking upright on flat fuze , and secondly, to change the twine of food produced .
