Haplogroup R1b (R-M343), previously known as Hg1 and Eu18, is a human Y-chromosome haplogroup.. It is the most frequently occurring paternal lineage in Western Europe, as well as some parts of Russia (e.g. the Bashkirs) and across the Sahel in Central Africa, namely: Cameroon, Chad, Guinea, Mauritania, Mali, Niger, Nigeria and Senegal (concentrated in parts of Chad with concentration in the ...
Haplogroup R1b probably originated in Eurasia prior to or during the last glaciation. It is the most common haplogroup in Western Europe and Bashkortostan ( Lobov 2009 ). It may have survived the last glacial maximum , [ 19 ] in refugia near the southern Ural Mountains and Aegean Sea .(
At Palenque, in addition to haplogroup R1b being found, including haplogroup R1b-V88, haplogroup E1b1a-M2 was found, which includes its sub-lineages (e.g., ...
Villabruna 1 is significant in terms of the genetic history of Europe: the remains were found to carry Y-DNA haplogroup R1b1a-L754* (xL389,V88). This is the oldest documented example of haplogroup R1b found anywhere. [8]
The proposed candidates include haplogroup C3, haplogroup Q, haplogroup R1b, haplogroup C2, [85] and haplogroup O. [ 86 ] Y chromosome haplogroup C2c1a1a1-M407 is carried by Mongol descendants of the Northern Yuan ruler from 1474–1517, Dayan Khan , who is a male line descendant of Genghis Khan which was found out after geneticists in Mongolia ...
Like other Western Europeans, among Spaniards and Portuguese the Y-DNA Haplogroup R1b is the most frequent, occurring at over 70% throughout most of Spain. [70] R1b is particularly dominant in the Basque Country and Catalonia, occurring at rate of over 80%. In Iberia, most men with R1b belong to the subclade R-P312 (R1b1a1a2a1a2; as of 2017).
Mt-haplogroup U5 arose in Europe just prior to the LGM, between 35 and 25 thousand years ago. [65] The 14,000 year old Villabruna 1 skeleton from Ripari Villabruna, Italy, is the oldest identified bearer of Y-haplogroup R1b (R1b1a-L754* (xL389,V88)) found in Europe, likely brought in from eastern introgression.

Haplogroup R1b is dominant throughout Western Europe. While it was once seen as a lineage connecting Britain and Ireland to Iberia, where it is also common, it is now believed that both R1b and R1a entered Europe with Indo-European migrants likely originating around the Black Sea ; [ 8 ] R1a and R1b are now the most common haplotypes in Europe.
