What is the history of the American Indians?
About 25,000 years ago, Native Americans’ ancestors split from the people living in Siberia. Later, they moved across a land bridge connecting Siberia and Alaska, making it into the Pacific Northwest between 17,000 and 14,000 years ago.
Immigration to the United States from India started in the early 19th century when Indian immigrants began settling in communities along the West Coast. Although they originally arrived in small numbers, new opportunities arose in middle of the 20th century, and the population grew larger in following decades.
According to an autosomal genetic study from 2012, Native Americans descend from at least three main migrant waves from East Asia. Most of it is traced back to a single ancestral population, called ‘First Americans’.
According to David Reich, a geneticist at Harvard Medical School and a member of the research team, the new DNA sequence also shows that Native Americans and people from East Asia have more Neanderthal DNA, on average, than Europeans.
Red Indian is an offensive term for a native North American. The use of the term Indian for the natives of the Americas originated with Christopher Columbus, who mistakenly believed that the Antilles were the islands of the Indian Ocean, known to Europeans as the Indies.
Greenfield Lake, Wilmington, NC 1950The Cherokee, members of the Iroquoian language group, are descended from the native peoples who occupied the southern Appalachian Mountains beginning in approximately 8000 b.c. By 1500 b.c., a distinct Cherokee language had developed, and by 1000 a.d.
All major ABO blood alleles are found in most populations worldwide, whereas the majority of Native Americans are nearly exclusively in the O group. O allele molecular characterization could aid in elucidating the possible causes of group O predominance in Native American populations.
Only one Neanderthal’s blood had been typed in the past, and was found to be type O under the ABO system used to classify the blood of modern humans. Since all chimpanzees are type A, and all gorillas are type B, it was assumed that all Neanderthals were type O.
East Asians seem to have the most Neanderthal DNA in their genomes, followed by those of European ancestry. Africans, long thought to have no Neanderthal DNA, were recently found to have genes from the hominins comprising around 0.3 percent of their genome.
First discovered in Czechia, the woman known to researchers as Zlatý kůň (golden horse in Czech) displayed longer stretches of Neanderthal DNA than the 45,000-year-old Ust’-Ishim individual from Siberia, the so-far oldest modern human genome.
