Documentary, Genetic history of P1-M45 Native American migration - R1 & Q people passing the Bering Strait 2 <br />Link; https://en.wikipedia.org/wiki/Genetic_history_of_the_Indigenous_peoples_of_the_Americas <br /><br />Haplogroups Q and R, specifically subclades of P1-M45, are key markers in the genetic history of Native American migration from Asia. P1-M45 is believed to have originated in Central Asia or Siberia. Haplogroup Q (Q-M242) is dominant among Native Americans, while R (R-M207) is more prevalent in Europe and Central Asia. The presence of these haplogroups, particularly R1 subclades, in both North America and Siberia suggests a prehistoric migration from Asia. <br />Here's a more detailed look: <br />Haplogroup P1 (P-M45): <br />This is the parent haplogroup of both Q and R, with basal P1* found in Siberia and Central Asia. <br />Haplogroup Q (Q-M242): <br />This haplogroup is a primary lineage among Native Americans, likely arriving in the Americas via Beringia during a prehistoric migration. <br />Haplogroup R (R-M207): <br />While R is not as prevalent in the Americas as Q, it is present and shares a common ancestor with Q in P1-M45. R1 subclades, especially R1b, are commonly found in Europe and have also been identified in North America, suggesting a connection to migrations from Asia. <br />Migration Patterns: <br />One theory suggests an initial migration from southern central Siberia into the Americas, extending southward, followed by a later migration from eastern Siberia to North and Central America. <br />Ancestry: <br />Native American ancestry is a mix of East Asian and Paleolithic Siberian (Ancient North Eurasian) lineages, with the Ancient North Eurasian component potentially linked to the R haplogroup. <br />Further Research: <br />The specific migration routes and the relationships between R subclades in different populations are still areas of ongoing research.
