Indigenous American Genetic Studies
The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the Settlement of the Americas, initial peopling of the Americas during about 20,000 to 14,000 years ago (20–14 kya), and European colonization of the Americas, European contact, after about 500 years ago. The first period of Indigenous peoples of the Americas, Indigenous American genetic history is the determinant factor for the number of genetic lineages, zygosity mutations and founding haplotypes present in today's Population history of Indigenous peoples of the Americas, Indigenous American populations. Indigenous American populations descend from an Ancient Paleo-Siberian, Ancient Paleo-Siberian population, itself a combination of an East Asian people, Ancient East Asian lineage which diverged from other East Asian peoples prior to the Last Glacial Maximum, between 36,000 and 25,000 years ago, and subsequently migrated into Siberia, were they merged with a primarily West Eur ...

Settlement Of The Americas
The settlement of the Americas began when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26,000 to 19,000 years ago). These populations expanded south of the Laurentide Ice Sheet and spread rapidly southward, occupying both North and South America, by 12,000 to 14,000 years ago. The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians. Indigenous peoples of the Americas have been linked to Siberian populations by linguistic factors, the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA. While there is general agreement that the Americas were first settled from Asia, the pattern of migration and the place(s) of origin in Eurasia of the peoples who migrated to the Americas remain unclear ...
