Haplogroup R-M269

R-M269 had formerly been dated to the Upper Paleolithic, but by about 2010 it was thought to have formed near the beginning of the Neolithic Revolution, about 10,000 years ago. More recent archaeogenetics studies since 2015, however, strongly suggest an origin among Eneolithic hunter-gatherers from eastern Europe. Balaresque et al. (2010) based on the pattern of Y-STR diversity argued for a single source in the Near East and introduction to Europe via Anatolia in the Neolithic Revolution. In this scenario, Mesolithic hunter-gatherers in Europe would have been nearly replaced by the incoming farmers. By contrast, Busby et al. (2012) could not confirm the results of Balaresque et al. (2010) and could not make credible estimates of the age of R-M269 based on Y-STR diversity. Furthermore, more recent studies have found that the Y-DNA of Early European Farmers is typically haplogroup G2a. According to Lazaridis et al. (2022), "the most likely hypothesis" is that the entire R-M269 clade originated "in the North Caucasus and steppe to the north". The subclade R-P311 is substantially confined to Western Europe in modern populations. R-P311 is absent from Neolithic-era ancient DNA found in Western Europe, strongly suggesting that its current distribution is due to population movements within Europe taking place after the end of the Neolithic. The three major subclades of P311 are U106 (S21), L21 (M529, S145), and U152 (S28). These show a clear articulation within Western Europe, with centers in the Low Countries, the British Isles and the Alps, respectively. These lineages are associated with the non-Iberian steppe-related groups of the Bell Beaker culture, and demonstrate the relationship between steppe-related ancestry and R1b-M269 subclades, which are "the major lineage associated with the arrival of Steppe ancestry in western Europe after 2500 BC". ==Distribution==

European R1b is dominated by R-M269. It has been found at generally low frequencies throughout central Eurasia, but with relatively high frequency among the Bashkirs of the Perm region (84.0%) and Baymaksky District (81.0%). This marker is present in China and India at frequencies of less than one percent. The table below lists in more detail the frequencies of M269 in regions in Asia, Europe, and Africa. Distribution of R-M269 in Europe increases in frequency from east to west. It peaks at the national level in Wales at a rate of 92%, at 82% in Ireland, 70% in Scotland, 68% in Spain, 60% in France (76% in Normandy), about 60% in Portugal, 50% in Germany, 50% in the Netherlands, 47% in Italy, 45% in Eastern England, 43% in Denmark and 42% in Iceland. It is as high as 95% in parts of Ireland. It is also found in some areas of North Africa, where its frequency peaks at 10% in some parts of Algeria. M269 has likewise been observed among 8% of the Herero in Namibia. The R-M269 subclade has been found in ancient Guanche (Bimbapes) fossils excavated in Punta Azul, El Hierro, Canary Islands, which are dated to the 10th century (~44%). In western Asia, R-M269 has been reported in 29.2% of Assyrian males from Iran. Haplogroup R1b1 and its subclades in Asia. M269* (xL23) is found at highest frequency in the central Balkans notably Kosovo with 7.9%, North Macedonia 5.1% and Serbia 4.4%. the type of R1b found in the recently analyzed Yamna remains of the Samara Oblast and Orenburg Oblast. Especially Western European R1b is dominated by specific sub-clades of R-M269 (with some small amounts of other types found in areas such as Sardinia). Within Europe, R-M269 is dominated by R-M412, also known as R-L51, which according to Myres et al. (2010) is "virtually absent in the Near East, the Caucasus and West Asia." This Western European population is further divided between R-P312/S116 and R-U106/S21, which appear to spread from the western and eastern Rhine river basin respectively. Myres et al. note further that concerning its closest relatives, in R-L23*, it is "instructive" that these are often more than 10% of the population in the Caucasus, Turkey, and some southeast European and circum-Uralic populations. In Western Europe it is present but in generally much lower levels apart from "an instance of 27% in Switzerland's Upper Rhone Valley." Population studies which test for M269 have become more common in recent years, while in earlier studies men in this haplogroup are only visible in the data by extrapolation of what is likely. The following gives a summary of most of the studies which specifically tested for M269, showing its distribution (as a percentage of total population) in Europe, North Africa, the Middle East and Central Asia as far as China and Nepal. ==Sub-clades==

R1b1a1a2a (R-L23) R-L23* (R1b1a1a2a*) is now most commonly found in Europe, Anatolia, the Caucasus. R1b1a1a2a1 (R-L51) R-L51* (R1b1a1a2a1*) is now concentrated in a geographical cluster centred on southern France and northern Italy. R1b1a1a2a1a (R-L151) R-L151 (L151/PF6542, CTS7650/FGC44/PF6544/S1164, L11, L52/PF6541, P310/PF6546/S129, P311/PF6545/S128) also known as R1b1a1a2a1, and its subclades, include most males with R1b in Western Europe. R1b1a1a2a1a1 (R-U106) This subclade is defined by the presence of the SNP U106, also known as S21 and M405. It appears to represent over 25% of R1b in Europe. In terms of total population numbers, its epicenter is Central Europe, where it comprises 60% of R1 combined. though is also found occasionally among Iberians in general. The first time it was located (Bosch 2001) it was described as H102 and included seven Basques and one Andalusian. R-M167 R-M167 is a subclade of R-DF27 defined by the presence of the marker M167. 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. He found it relatively common among Basques (13/117: 11%) and Catalans (7/32: 22%). Other occurrences were found among other French, British, Spaniards, Béarnais, and Germans. In 2000 Rosser et al., in a study which tested 3616 men in various populations 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%), Spaniards (2%), Southern Portuguese (2%), and in single occurrences among Romanians, Slovenians, Dutch, Belgians and English.::In 2001 Bosch described this marker as H103, in 5 Basques and 5 Catalans. In 2008 two research papers by López-Parra R-L165 This subclade is defined by the presence of the marker S68, also known as L165. It is found in England, Scandinavia, and Scotland (in this country it is mostly found in the Northern Isles and Outer Hebrides). It has been suggested, therefore, that it arrived in the British Isles with Vikings. R-U152 R-U152 is defined by the presence of the marker U152, also called S28. reported frequency peaks in Northern and Central Italy and France. Out of a sample of 135 men in Tyrol, Austria, 9 tested positive for U152/S28. Far removed from this apparent core area, Myres et al. also mention a sub-population in north Bashkortostan, where 71% of 70 men tested belong to R-U152. They propose this to be the result of an isolated founder effect. Ancient samples from the central European Bell Beaker, Hallstatt and Tumulus cultures belonged to this subclade. Analyzed Iron Age Latins, Etruscans and Alpine Celts, dating between 1000 and 100 BCE, belonged primarily to haplogroup R1b-U152 (including the clades L2, Z56 and Z193). Ancient samples of Cenomani Cisalpine Gauls from Verona who lived between the 3rd and 1st centuries BCE were predominantly R-U152. U152 is also found at low frequencies of around 3%-4% in Morocco, Algeria, and Tunisia, pointing to direct maritime contacts between the European and North African sides of the western Mediterranean. R-L21 R-L21, also known as R-M529 and R-S145, • R-L159.2 is a subclade of R-DF13, defined by the marker L159/S169. It is known as R-L159.2 because of an unrelated parallel mutation (L159.1), found within haplogroup I2a1a1a (a.k.a. I-L158 or I-M26). Consequently, some Y-DNA trees exclude L159/S169 completely, on the basis that it may be an unreliable marker. For instance, as of 2024, Yfull refers to an equivalent subclade as R-FGC80001 (i.e. R-L21 > R-S552 > R-DF13 > R-Z255 > R-FGC80001). R-L159.2 appears to be associated with the Laigin, an ethno-tribal group, after whom the Kingdom of Leinster was named. It is common in males from coastal areas surrounding the Irish Sea, including western Wales, the Isle of Man and the Hebrides; R-L159.2 has also been found at significant levels in Norway, western and southern Scottish mainland, parts of England, northwest France, and northern Denmark. • R-L193: this subclade within R-DF13 is defined by the presence of the marker L193. Many surnames with this marker are associated geographically with the western "Border Region" of Scotland. A few other surnames have a Highland association. R-L193 is a relatively young subclade likely born within the last 2000 years. • R-L226, under R-DF13, is defined by the presence of the marker L226, also known as S168. Commonly referred to as Irish Type III, it is concentrated in central western Ireland and associated with the Dál gCais kindred. • R-L371: a subclade within R-DF13 defined by the presence of the marker L371 – sometimes referred to as the "Welsh modal haplotype". It is associated with ancient Welsh kings and princes. == See also ==
