The Na-Dene, Inuit, and Native Alaskan populations exhibit haplogroup Q (Y-DNA) mutations, but are distinct from other Indigenous Americans with various mtDNA and autosomal DNA (atDNA) mutations. [ 14 ] [ 50 ] [ 51 ] This suggests that the earliest migrants into the northern extremes of North America and Greenland derived from later migrant ...
The data developed by these mainstream scientists tell us that the Native Americans have very distinctive DNA markers and that some of them are most similar, among old world populations, to the DNA of people anciently associated with the Altay Mountains area of central Asia. These evidences from a genetic perspective agree with a large body of ...
Who We Are and How We Got Here is a 2018 book on the contribution of genome-wide ancient DNA research to human population genetics by the geneticist David Reich.He describes discoveries made by his group and others, based on analysis and comparison of ancient and modern DNA from human populations around the world.
Reenactment of a Viking landing in L'Anse aux Meadows. Pre-Columbian transoceanic contact theories are speculative theories which propose that visits to the Americas, interactions with the Indigenous peoples of the Americas, or both, were made by people from elsewhere prior to Christopher Columbus's first voyage to the Caribbean in 1492.

DNA analysis of a 8,500-year-old skeleton has provided a new twist in a long running dispute over which population it belongs to. The skeleton — dubbed the Kennewick Man or the Ancient One ...
Heterozygosity averages among the ten loci from the K'iche' at 0.133, the Buctzotz group at 0.249 and the Kaqchikel 0.171. Inter-population diversity was reported in reference to differences in allelic frequencies between the Mayans and other Native Americans, Europeans, Africans and Asians as (P<0.001). [2]
The team also detected a small number of “hybrid lice” — reflecting a mix of the two clusters — that were mostly found in the Americas, which she said she interpreted as a “signal of ...
Figure 2. Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia (long chronology, single source model). The Ancient Beringian (AB) is a human archaeogenetic lineage, based on the genome of an infant found at the Upward Sun River site (dubbed USR1), dated to 11,500 years ago. [1]
