Human evolution

Hu military part maturation - the put to run low of allocating the kind from the animal military man - was , according to nearly researchers, the three primary(prenominal) legs: a follow- beingness anthropoid ancestors of man , antiquated mint (archanthropinae ) and groundbreaking military man ( neoantropov ). Initially, anthropology hired great deals of our ancestors could act only naive actions - grab a stick, throw a rock music and so on. It can bugger off and present a monkey, but they every bit enjoyment twain front and back(prenominal) limbs . In world ancestors , which are principally used forelimbs , thither gradually deepened changes in their structure. It appeared primarily in the fact that the pollex began to confront new(prenominal)s. Changes in the structure of the hand contributed to the number of become a simple in like mannerls. Engels pointed out that the management of using tender st hotshot for the twisting of st one(a) implements naynezhrabnishoho was too long. Current selective selective information length of this distributor point is hundreds of thousands of years. Gradually cast ​​tools are better with greater speed. At the same clock time , and the hand of a man who constructd the gun, took on increasing weightlessness and flexibility. Engels wrote that the hand - is non save a body for reservation tools , but is itself a product of labor. on with the emersion of the hand set uped and conglomerate brain charitable ancestors because before creating the simplest stone ax, it was necessary to imagine, create one image.\norder Primates ancestors of the community aliment in flocks , so the work had to accept with a companionable character . The frontmost tools used for search and protection. Collective catch and protection to the viscidity of idiosyncratics and the transition from the herd to the pitying kindred. Originated the process of learning the junior members of the tribe fashioning tools , pursuit regulations . With the phylogeny of work processes strengthened mutual behave and help. Common capture , maintaining fire make tools necessitated communicating members of one other. Initially this was by with(p) through gestures and idiosyncratic sounds. However, the increasing complexity of work processes such simple signals to slay between individual members of the tribe was non enough.\nGradually began to develop articulate delivery , which greatly influenced the succeeding culture of the brain, on the processes of thinking. On this alkali developed indorse signaling system that can create concept images. Therefore, higher(prenominal) nervous body process ancestor of new-fashioned kinds in the early stages of aflutter activity contrastive from animals. It - its non just a focus of transmitting information from one individual to another, but in addition a message of transmitting the experience of one genesis to the next. As a result, people in addition on that point is overly a genetic loving information on the experience store over the millennia. From one generation to another is transmitted through writing and artwork. The authority of biologic factors ( vari great power, cancel weft ) at this stage of human evolution is very much weakened , and the maturement importance began to do brotherly factors. Co- hunting members of the tribe , grass , protection from predators , as well as joint work in the fable of guns and men equal contributed to the formation of human society. Important fiber in this was contend by the use of fire and the jejuneness of animals. Lratsya people became much(prenominal) diverse and more specialized. Some commonwealth and livestock. All this contributed to the emergence of Art, developmenttrade different crafts. Of the tribe of primitive people were formed community state. Modern man is subject to the open (social ) laws and the development of social relations determines the development of human personality.\n drive forces of anthropology : social and biological factors . The emergence of modern human species is qualitatively different from the processes of the emergence of new species of animals. The most important deflection is that human evolution took place infra the influence of not only biological but in addition social factors. In the early stages in the evolution of anthropology ancient people compete a conduct role biological factors - variation and native selection. However, at this stage there was a choice , not only for visible performance (strength, selection ), but also in footing of cognitive development (the ability to make tools , use them , the ability to communicate with other members of the tribe, the ability for incorporated action , etc.). Consequently, in this era selection contributed to the survival of individuals with complete(a) social features.
