The genetic divergence of R1a (M420) is estimated to have occurred 25,000 [2] years ago, which is the time of the last glacial maximum.A 2014 study by Peter A. Underhill et al., using 16,244 individuals from over 126 populations from across Eurasia, concluded that there was "a compelling case for the Middle East, possibly near present-day Iran, as the geographic origin of hg R1a".

The genetic history of Europe includes information around the formation, ethnogenesis, and other DNA-specific information about populations indigenous, or living in Europe. European early modern human (EEMH) lineages between 40 and 26 ka ( Aurignacian ) were still part of a large Western Eurasian "meta-population", related to Central and ...
R1b1a1a2 (M269) is the second most common Y-DNA haplogroup found among Indigenous Americans after Y-DNA haplogroup Q. [ 66 ] The R1b1a1a2 (M269) lineages commonly found in Native Americans are in most cases belonged to R1b1a1a2 (M269) subclade most common in western Europeans, and its highest concentration is found among a variety of the ...
Haplogroup H is a human mitochondrial DNA (mtDNA) haplogroup. The clade is believed to have originated in Southwest Asia , near present day Syria, [ 1 ] around 20,000 to 25,000 years ago. Mitochondrial haplogroup H is today predominantly found in Europe, and is believed to have evolved before the Last Glacial Maximum (LGM).
A recent Y-DNA study from 2018 on a modern sample of 113 individuals from Volterra, a town of Etruscan origin, Grugni at al. keeps all the possibilities open, although the autochthonous scenario is the most supported by numbers, and concludes that "the presence of J2a-M67* (2.7%) suggests contacts by sea with Anatolian people, the finding of ...
Y chromosome haplogroup distribution of Turkish people [4]. A 2021 study which looked at whole genomes and whole-exomes of 3,362 Turkish people found that the most common Y chromosome haplogroups were J2a, R1b, and R1a (18.4%, 14.9%, and 12.1% respectively).
The technology to test for DF27 was developed by Thomas Krahn, then of Family Tree DNA. This marker was discovered to exist among people who had taken part in the Human Genome Diversity Project . Richard A. Rocca made a pioneering study of DF27, which was published in 2012 in the article Discovery of Western European R1b1a2 Y Chromosome ...
DNA analysis on native European Americans by geneticist Mark D. Shriver showed an average of 0.7% Native African admixture and 3.2% Native American admixture. [75] The same author, in another study, claimed that about 30% of all European Americans, approximately 66 million people, have a median of 2.3% of native African admixture. [76]
