Historically, our knowledge of the kansoittaen North America, announced that the archaeological, geographical and ethnographic evidence. This video claimed that the ancestors of modern Native Americans moved to North America, Asia, about 15.000 to 13.000 years ago, shortly after the end of the Pleistocene period. With the development of new technologies, however, new evidence suggests that sometimes challenges a long anthropological theories. Such a restructuring of our understanding of early kansoittaen of the Americas is currently running. This new understanding of American Indian time depth in the western hemisphere is largely due to the dawn of molecular genetics techniques and theories applied kansoittaen questions about early America.
Two types of information are the basis for molecular genetic evidence to suggest that the original migration of the Americas originated somewhere in South-Central Siberia between 35.000 to 20,000 years before present. These dates are much earlier than previous estimates based on carbon measurements, the analysis of archaeological material, even as new items, such as the Gault in Texas, the time during this period. Using the frequency of genetic markers can be found in both mitochondrial DNA (mtDNA) or Y-chromosome DNA, the new understanding of kansoittaen U.S. claims that the first migrants, after what was called the north-west coast route. These early migrants in the North-East Asia has been speculated, went north-west coast of North America until south of the Pleistocene ice age glaciers which a large part of Canada, when they extended to all areas of the continent covered. These early American Indians are thought to have imported mtDNA haplogroups AD and the Y-chromosome haplogroup P-M45a and Q-242/Q-M3 haplotypes. Another migration is also speculated to have been in America, either at the same time or slightly later, that mtDNA haplogroup X and the Y-chromosome haplogroups P-M45b, C-M130 and M17-R1a1. The third and last migration is assumed to have occurred after the last ice age in northern North America. The basis of genetic evidence, it is also possible to position in the geographic region in North-East Asia, where these early immigrants are more likely to fire. Thus, the major Y haplotype present in most American Indians, are traced back to the last common ancestor of the Siberians, namely the market and away from the Altaians Yenissey River Basin and Altai Mountains, respectively. To go back, the next common ancestor gave rise to the genetics of the Y chromosome is also white, probably in the Central Eurasian region. MtDNA evidence supports the same conclusion, even if the country takes first North Asian Americans somewhere between contemporary Mongolia and Siberia, probably around the current Tibet and Ulan Bator. This is based on the evidence that all mtDNA lineages found in Siberia, except for line B, which can be found in Ulan Bator in the North-East Asia. No molecular genetic evidence is found for theories that claim to support Pleistocene Europeans, Polynesians Ocean going, seafaring Persians, or other cultural groups in America. In fact, molecular genetics, the screen is quite impressive: contemporary American Indian, Alaska Native, and First Nation people for parents originally moved to North America-Asia. Exact times when these migrations took place are still controversial, but the molecular genetic evidence is strongly in favor of more time in the depths of human habitation in the Americas than previously considered.
