It arose comparatively recently, after the beginning of the
European Bronze Age, and is mostly prevalent in the population of the
Pyrenees region.
Distribution
The first author to test for this marker (long before current haplogroup nomenclature existed) was Hurles in 1999, who tested 1158 men in various populations.[1] He found it relatively common among Basques (13/117: 11%) and
Catalans (7/32: 22%). Other occurrences were found among other Spanish,
Béarnais, other French, British and
Germans.
In 2000 Rosser et al., in a study which tested 3616 men in various populations[3] also tested for that same marker, naming the haplogroup Hg22, and again it was found mainly among Basques (19%), in lower frequencies among French (5%),
Bavarians (3%), Spanish (2%), Southern Portuguese (2%), and in single occurrences among
Romanians,
Slovenians,
Dutch,
Belgians and English.
In 2001 Bosch described this marker as H103, found in 5 Basques and 5 Catalans.[4] However a study in 2005 of Spanish Basques found lower levels of this haplogroup than those recorded in Basques by the earlier studies - only four samples out of the 168 tested.[5]
In 2008 a study by Adams and colleagues covered the whole of the Iberian Peninsula. It found the highest levels of this haplogroup in Catalonia.[6] In the same year a study by López-Parra and colleagues concentrated on the populations of the Spanish
Pyrenees. They discovered a high levels of this haplogroup in the central and eastern
Pyrenees. The highest level so far discovered (48%) was found in the
Val d'Aran, Catalonia.[7]
In a larger study specifically of Portugal in 2006, with 663 men tested, Beleza et al. showed low levels of this haplogroup ( described in the paper as R1b3f) in all the major regions, from 1.5%-3.5%. Breaking the results down to district, only Lisboa (at 5.7%) had over 5%.[8]
A 2012 study by Martinez-Cruz et al. found the following percentages of SRY2627: 7% in the three French departments of the Pays de Basque, 16% in Bearn, 14% in Bigorre, 7% in Chalosse, 6% in the Basque regions of Spain, 15% in La Rioja, and 19% in northern Aragon.[9]
According to an "analysis of the R1b-DF27 haplogroup" published in August 2017, SRY2627 (M167) appeared 3,458 years before present in Spain (Aragon).[10]

^K-M2313*, which as yet has no phylogenetic name, has been documented in two living individuals, who have ethnic ties to India and South East Asia. In addition, K-Y28299, which appears to be a primary branch of K-M2313, has been found in three living individuals from India. See: Poznik op. cit.;
