Maybe, see the map above.
That would be a map of R1b distribution in modern
Europe. Note the 15% frequency in Turkey as well.
However, consider this:R1b Distribution
Haplogroup R1b is the most frequent Y-chromosome haplogroup in Western Europe, where its frequency is highest.
More specifically, its frequency is highest in Atlantic Europe and, due to European emigration, in North America, South America, and Australia. In southern England, the frequency of R1b is about 70%, and in parts of north and western England, Spain, Portugal, France, Wales, Scotland and Ireland the frequency of R1b is greater than 90%. It is also found among Italians, particularly in northern Italy.
R1b is also present at lower frequencies throughout Eastern Europe, although diversity is higher than in western Europe, suggesting an ancient migration of R1b from the east.It also appears in North Africa where its frequency surpasses 10% in some parts of Algeria.
Haplogroup R1b is defined by the presence of single nucleotide polymorphism (SNP) M343, which was discovered in 2004. From 2002 to 2005, R1b was defined by the presence of SNP P25. Prior to 2002, today's Haplogroup R1b had a number of names in differing nomenclature systems, such as Hg1 and Eu18.
Origins: I. Dupandunlop argued in 2002 that Basque genes and hence haplogroup R1b1b2 (R1b1c) were the most representative of Paleolithic European population
. In this she followed previous research done fundamentally on mitochondrial DNA. Many other authors have followed her conclusions for further research, assuming thereafter that R1b1b2 (R1b1c) is of Paleolithic origin.
Based on R1b frequency and variability, most researchers considered the genetic pool of western European countries - Belgium, France, Germany, Ireland, the Netherlands, north Italy, Portugal, Spain and United Kingdom - to date back to Paleolithic times, noticing the overlap between R1b previously estimated age (about 25,000 to 30,000 years ago)
and the European Upper Paleolithic. The hypothesis met apparent confirmation in the fact that the Basques, who traditionally have been considered descendants of the European Paleolithic strata, have one of the highest frequencies of R1b in the world.
However, linguistic-historical studies performed by paleo-Hispanists, and also some genetic research, the latter focusing on the lower R1b1b2 (R1b1c) diversity among Basques, disputed either their assumed remote Hispanic origins or their position as the group who has best conserved their Paleolithic European genetic ancestry, and deny Basque territory represents a mayor focus of expansion:
"Contrary to previous suggestions, we do not observe any particular link between Basques and Celtic populations beyond that provided by the Paleolithic ancestry common to European populations, nor we find evidence supporting Basques as the focus of major population expansions"
Despite lower frequencies, diversity is higher in Eastern Europe than in the west. Analysis indicates that all European variants of R1b shared an existence in Kazakhstan before migrating to Russia and then splitting into two major migrations, primarily along rivers and coastlines.
Diversity peaks also occur in other low frequency areas, especially northern Croatia.
By 2008, T. Karefet et al., based on the latest discoveries on polymorphisms, rearranged the human paternal phylogenetic tree by adding one new haplogroup and altering some of the estimated ages of previously known haplogroups, including the parent haplogroup to R1b, R1, now considered to have originated 18,500 BP.Studies from Volga-Urals on the border of Europe and Asia have revealed high frequencies of R1b1b2 in Bashkirs, although the genetic diversity is low, suggesting a founder effect.R1b1b2: Most of the present-day European males with the M343 marker also have the P25 and M269 markers. These markers define the R1b1b2 subclade.This subgroup is believed by some to have existed before the last Ice Age and has been associated with the Aurignacian culture (32,000 - 21,000 BC). Archeological evidence supports the view of the arrival of Aurignacian culture to Anatolia from Europe during the Upper Paleolithic rather than from the Iranian plateau.Although the precise route of the M269 marker is not known, it is theorized to have originated in Central Asia/South Central Siberia. It could have entered prehistoric Europe from the area of Ukraine/Belarus or Central Asia (Kazakhstan) via the coasts of the Black Sea and the Baltic Sea. It is considered widespread in Europe throughout the Paleolithic already before the last Ice Age.Traditionally this culture is associated with the Cro-Magnon people, the first modern humans to enter Europe. However, this view has recently been challenged. The people of the Aurignacian culture were the first documented human artists, making sophisticated cave paintings. Famous sites include Lascaux in France, Altamira in Spain and Valley of Foz Côa in Portugal.
The glaciation of the ice age intensified, and the continent became increasingly uninhabitable. The genetic diversity narrowed through founder effects and population bottlenecks, as the population became limited to a few coastal refugia in Southern Europe. The present-day population of R1b in Western Europe are believed to be the descendants of a refugium in the Iberian Peninsula (Portugal and Spain), where the R1b1b2 haplogroup may have achieved genetic homogeneity. As conditions eased with the Allerød Oscillation in about 12,000 BC, descendants of this group migrated and eventually recolonised all of Western Europe, leading to the dominant position of R1b in variant degrees from Iberia to Scandinavia, so evident in haplogroup maps.A second R1b1b2 population, reflected in a somewhat different distribution of haplotypes of the more rapidly varying Y-STR markers, appear to have survived alongside other haplogroups in Eastern Europe. However, they do not have the same dominance that R1b has in Western Europe. Instead the most common haplogroup in Eastern Europe is haplogroup R1a1.
Note that haplogroup R1b and haplogroup R1a first existed at very different times. The mutations that characterize haplogroup R1b occurred ~30,000 years bp, whereas the mutations that characterize haplogroup R1a occurred ~10,000 years bp.
(In earlier literature the M269 marker, rather than M343, was used to define the R1b haplogroup. Then, for a time [from 2003 to 2005] what is now R1b1b2 was designated R1b3. From 2005 to 2008 it was R1b1c. This shows how nomenclature can evolve as new markers are discovered and then investigated).
