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 ...
This article summarizes the genetic makeup and population history of East Asian peoples and their connection to genetically related populations such as Southeast Asians and North Asians, as well as Oceanians, and partly, Central Asians, South Asians, and Native Americans. They are collectively referred to as "East Eurasians" in population genomics.
Results from the team's genetic analysis were published in January 2018 in the scientific journal Nature. The analysis compared the infant's genomes with both ancient and contemporary genomes. The results suggested that the pre-"Ancestral Native American" lineage derived from the East Asian lineage after 36 kya, with gene flow until about 25 kya.
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 ...
Genetic studies have used high resolution analytical techniques applied to DNA samples from modern Native Americans and Asian populations regarded as their source populations to reconstruct the development of human Y-chromosome DNA haplogroups (yDNA haplogroups) and human mitochondrial DNA haplogroups (mtDNA haplogroups) characteristic of ...
Maya intra-population variation has been examined by means of the following tests: Human leukocyte antigen (HLA) polymorphisms, polymorphic Alu insertions, mitochondrial DNA (mtDNA), and Y chromosome data. The results indicate that ancestors of the Mayas made a finite number of entries into the Americas over the Bering land bridge. [1]
A genealogical DNA test is a DNA-based genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnic mixture of an individual. Since different testing companies use different ethnic reference groups ...
Some 20 years ago, David Reed, a coauthor of the new study and a researcher and curator at the Florida Museum of Natural History, found that human head lice are composed of two ancient lineages ...
