Approximate distribution of Haplogroup R1b in Europe.

In human genetics, Haplogroup R1b is the most frequently occurring Y-chromosome haplogroup in Western Europe, parts of central Eurasia (for example Bashkortostan[3]), and in parts of sub-Saharan Central Africa (for example around Chad and Cameroon). R1b is also present at lower frequencies throughout Eastern Europe, Western Asia, Central Asia, and parts of North Africa. Due to European emigration it also reaches high frequencies in the Americas and Australia. While Western Europe is dominated by the R1b1b2 (R-M269) branch of R1b, the Chadic-speaking area in Africa is dominated by the branch known as R1b1a (R-V88). These represent two very successful "twigs" on a much bigger "family tree".

Nomenclature

"R1b", "R1b1", and so on are "phylogenetic" or family tree based names which explain the branching of the family tree of R1b. For example R1b1a and R1b1b would be branches of R1b1, descending from a common ancestor. This means that these names can change with new discoveries.

The alternative way of naming haplogroups is to refer to the mutations used to define and identify them, for example "R-M343" which is equivalent to "R1b". Haplogroup R1b is in other words now identified by the presence of the single-nucleotide polymorphism (SNP) mutation M343, which was discovered in 2004.[4] From 2002 to 2005, R1b was defined by the presence of SNP P25.

Standardized naming as described above, both using phylogenetic or mutational systems, was first proposed in 2002 by the Y Chromosome Consortium. Prior to 2002, today's Haplogroup R1b had a number of names in differing nomenclature systems, such as Hg1 and Eu18.[5]

Further information: [[:Conversion table for Y chromosome haplogroups]]

After 2002, a major update of the YCC phylogenetic nomenclature was made in 2008 by Karafet et al. which took account of newer discoveries of branches which could be clearly defined by SNP mutations, including some which changed the understanding of R1b's family tree.[1] Since 2008 it has become increasing necessary to refer to the frequently updated listing made on the ISOGG website.[2]

Origin and dispersal

R1b is a sub-clade within the much larger Eurasian MNOPS "macro-haplogroup", which is one of the predominant groupings of all human male lines outside of Africa, and this whole group, along indeed with all of macro-haplogroup F, is believed to have originated in Asia.

Macro-haplogroup MNOPS

Haplogroup M. New Guinea, Melanesia, eastern Indonesia, and Polynesia.

Macro-haplogroup NO

Haplogroup N. Mainly found in North Asia and northeastern Europe.

Haplogroup O. Mainly found in East Asia, Southeast Asia, and Austronesia.

Macro-haplogroup P

Haplogroup R1b. Mainly found in Western Europe, Central Africa and South West Asia.

Haplogroup R2. Mainly found in South Asia.

Haplogroup S. New Guinea, Melanesia, and eastern Indonesia.

The point of origin of R1b is thought by many to lie in Eurasia, with one of the most recent article on this subject arguing for a likely origin in Western Asia.[6] T. Karafet et al. estimated the age of R1, the parent of R1b, as 18,500 years before present.[1]

In 2000 Ornella Semino and colleagues argued that R1b was ancient in Europe, and spread north from an Iberian Ice Age refuge after the Last Glacial Maximum.[7]This is one of main theories concerning the subject at hand and was supported by a mid 2010 study of the haplogroup R1b1b2 y-chromosome across Europe [8]

Barbara Arredi and colleagues were the first to point out that the distribution of R1b forms a cline from east to west, which is far more consistent with an entry into Europe from Western Asia with the spread of farming.[9] Their conclusions on the eastern origin of R1b were supported by two detailed studies based on large datasets published in 2010. Both detected that the earliest subclades of R1b are found in western Asia and the most recent in western Europe.[10] Another paper added to this perspective by using R1b as an example of a wave haplogroup distribution, in this case from east to west.[11] However Myres et al. (August 2010) remained undecided on the dating of the migration or migrations responsible for this distribution. While concentrating their attention on the Neolithic, they do not rule out earlier or later movements.[6]

Root of R1b tree

The identifiers below are those from the 2010 revision of the ISOGG tree.[2]

M343
still un‑defined

R-M343* (R1b*)

P25
still un‑defined

R-P25* (R1b1*)

V88

R-V88 (R1b1a). Most common Sub-Saharan African R1b.

P297
still un‑defined

R-P297* (R1b1b*)

M73

R-M73 (R1b1b1). Found in Central Asia.

M269
still un‑defined

R-M269* (R1b1b2*)

L23

R-L23 (R1b1b2a). Most common European R1b

R1b*

R1b* (that is R1b with no subsequent distinguishing SNP mutations) is extremely rare. Two cases were reported in a large study of Turkey.[4] In a study of Jordan it was found that no less than 20 out of all 146 men tested (13.7%), including most notably 20 out of 45 men tested from the Dead Sea area, were positive for M173 (R1) but negative for P25 and M269, mentioned above, as well as the R1a markers SRY10831.2 and M17, so they are either R1b* or R1a*.[12] Hassan et al. (2008) found an equally surprising 14 out of 26 (54%) of Sudanese Fulani who were M173+ and P25-.<[13] Wood et al. report 2 Egyptian cases of R1-M173 which were negative for SRY10831 (R1a1) and P25 (R1b1), out of a sample of 1122 males from various African countries, including 92 from Egypt.[14] Such cases could possibly be either R1b* (R-M343*) or R1a* (R-M420*) (demonstrating the importance of checking exact mutations tested when comparing findings in this field).

It is however also possible that some of the rare examples represent a reversion of marker P25 from a positive back to a negative ancestral state.[15]

Ancient clades within R1b1 (R-P25)

An up-to-date compilation of data taking the latest information into account can be found in Cruciani et al. (2010) which can be summarised as follows[16]. As will be discussed below however, in some parts of western and northwestern Europe, R-M269 frequencies can reach even higher levels.

R1b1*

R1b1*, like R1b* is rare. As mentioned above, examples are described in older articles, for example two in a sample from Turkey,[4] but most cases, especially in Africa, are now thought to be almost mostly in the more recently discovered sub-clade R-V88 (see below). Most or all examples of R1b therefore fall into subclades R1b1a (R-V88) or R1b1b (R-P297). Cruciani et al. in the large 2010 study found 3 cases amongst 1173 Italians, 1 out of 328 West Asians and 1 out of 156 East Asians.[16] Varzari found 3 cases in the Ukraine, in a study of 322 people from the Dniester-Carpathian region, who were P25 positive, but M269 negative.[17] Cases from older studies are mainly from Africa, the Middle East or Mediterranean, and are discussed below as probable cases of R1b1a (R-V88).

R1b1a

R1b1a is defined by the presence of SNP marker V88, the discovery of which was announced in 2010 by Cruciani et al.[16] Apart from individuals in southern Europe and Western Asia, the majority of R-V88 was found in northern and central Africa:

As can be seen in the above data table, R1b1a is found in northern Cameroon in west central Africa at a very high frequency, where it is considered to be caused by a pre-Islamic movement of people from Eurasia.[14][18]

Suggestive results from other studies which did not test for the full range of new markers discovered by Cruciani et al. have also been reported, which might be in R-V88.

  • Wood et al. reported high frequencies of men who were P25 positive and M269 negative, amongst the same north Cameroon area where Cruciani et al. reported high R-V88 levels. However they also found such cases amongst 3% (1/32) of Fante from Ghana, 9% (1/11) of Bassa from southern Cameroon, 4% (1/24) of Herero from Namibia, 5% (1/22) of Ambo from Namibia, 4% (4/92) of Egyptians, and 4% (1/28) of Tunisians.[14]
  • Luis et al. found the following cases of men M173 positive (R1), but negative for M73 (R1b1b1), M269 (R1b1b2), M18 (R1b1a1, a clade with V88, M18 having been discovered before V88) and M17 (R1a1a): 1 of 121 Omanis, 3 of 147 Egyptians, 2 of 14 Bantu from southern Cameroon, and 1 of 69 Hutu from Rwanda.[19]

R1b1a1

R1b1a1 is a sub-clade of R-V88 which is defined by the presence of SNP marker M18.[1] It has been found only at low frequencies in samples from Sardinia[20][21] and Lebanon.[22]

R1b1b

R1b1b is defined by the presence of SNP marker P297. In 2008 this polymorphism was recognised to combine M73 and M269 into one R1b1b cluster.[1] The majority of Eurasian R1b is within this clade, representing a very large modern population. Although P297 itself has not yet been much tested for, the same population has been relatively well studied in terms of other markers. Therefore the branching within this clade can be explained in relatively high detail below.

R1b1c

R1b1c is defined by the presence of SNP marker M335. This haplogroup was created by the 2008 reorganisation of nomenclature and should not be confused with R1b1b2, which was previously called R1b1c. Its position in relation to the much more populous sub-clade R1b1b is uncertain.[1] The M335 marker was first published in 2004, when one example was discovered in Turkey, which was classified at that time as R1b4.[4]

Major clades within R1b1b (R-P297)

R1b1b1 (R-M73)

R1b1b1 is defined by the presence of SNP marker M73. It has been found at generally low frequencies throughout central Eurasia,[20] but has been found with relatively high frequency among particular populations there including Hazaras in Pakistan (8/25 = 32%)[23]; and Bashkirs in Bashkortostan (62/471 = 13.2%), 44 of these being found among the 80 tested Bashkirs of the Abzelilovsky District in the Republic of Bashkortostan (55.0%).[3] High levels were also spotted in very small samples from particular ethnic groups in China in the study by Sengupta et al in 2006. This included the Naxi (4/8) and Uygur (3/8), but R-M73 individuals were also found in the small samples for Japan, and the Chinese Mongola, Tu, and Han.[23] Four R-M73 men were also found in a 523 man study of Turkey.[4]

In 2010, Myres et al. report that out of 193 R-M173 men found amongst 10355 widespread men, "all except two Russians occurred outside Europe, either in the Caucasus, Turkey, the Circum-Uralic and North Pakistan regions".[24]

R1b1b2 (R-M269)

R1b1b2 is defined by the presence of SNP marker M269. European R1b is dominated by R-M269. It has been found at generally low frequencies throughout central Eurasia,[20] and with relatively high frequency among Bashkirs of the Bashkortostan and Perm region (84.0%).[3] Out of 523 men tested across Turkey 76 tested positive for M269[4].

R-M269
Long-hand: R1b1b2 (formerly R1b1c, R1b3)
Defining SNP: M269
Parent Clade: R-P297

From 2003 to 2005 what is now R1b1b2 was designated R1b3. From 2005 to 2008 it was R1b1c.

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 it's closest relatives, in R-L23*, that 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 also present but in generally much lower levels apart from "an instance of 27% in Switzerland's Upper Rhone Valley".[6]

In articles published around 2000 it was proposed that this clade came into existence in Europe before the last Ice Age,[25] but more recently this scenario is no longer receiving much mainstream attention. A range of newer estimates for R1b1b2 are from 4,000 to a maximum of about 10,000 years ago, and coming from Western Asia via southeastern Europe.[2][9][6] Western European R1b is dominated by R-P310.[2] It is this Western European branch which is in turn dominated by U106 and P312, and the typical most common STR Y DNA signature for Western Europe, the so-called Atlantic Modal Haplotype, which is also sometimes referred to as "Haplotype 15".[2] "Haplotype 15" is contrasted with "Haplotype 35", which has long been noted as a distinct type of R1b1b2, more common towards the southeast of Europe. For example, in the Balkans, Georgia and Turkey "Haplotype 35" is prevalent[4]. In 2009, DNA extracted from the femur bones of 6 skeletons in an early-medieval burial place in Ergolding (Bavaria, Germany) dated to around 670 AD yielded the following results: 4 were found to be haplogroup R1b with the closest matches in modern populations of Germany. Ireland and the USA while 2 were in Haplogroup G2a.[26]

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 in Europe, North Africa, the Middle East and Central Asia as far as China and Nepal.

R1b1b2a1a1 (R-U106) - a sub-clade within R1b1b2

This subclade is defined by the presence of the marker U106, also known as S21 and M405.[2][41] It appears to represent over 25% of R1b in Europe.[2]

R1b1b2a1a2 (R-P312) - a sub-clade within R1b1b2

Along with R-U106, R-P312 is one of the most common types of R1b1b2 (R-M269) in Europe. It has been the subject of significant study concerning its sub-clades, and those so far recognized by the ISOGG website are summarized in the following table.[2]

R1b1b2a1a2b

This subclade is defined by the presence of the marker R-M153. It has been found mostly in Basques and Gascons, among whom it represents a sizeable fraction of the Y-DNA pool[42][43], though is also found occasionally among Iberians in general. The first time it was located (Bosch 2001[44]) it was described as H102 and included 7 Basques and one Andalusian.

R1b1b2a1a2c

This subclade is defined by the presence of the marker M167, also known as SRY2627. 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[45]. 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[46] 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, in 5 Basques and 5 Catalans.[44] Further regional studies have located it in significant amounts in Asturias, Cantabria and Galicia, as well as again among Basques.[44] Cases in the Azores and Latin America have also been reported. In 2008 two research papers by López-Parra[43] and Adams,[42] respectively, confirmed a strong association with all or most of the Pyrenees and Eastern Iberia.

In a larger study of Portugal in 2006, with 657 men tested, Beleza et al. confirmed similar low levels in all the major regions, from 1.5%-3.5%.[47]

R1b1b2a1a2d

This subclade is defined by the presence of the marker U152, also called S28[2]. Its discovery was announced in 2005 by EthnoAncestry[48] and subsequently identified independently by Sims et al. (2007).[41] Out of a sample of 135 men in Tyrol, Austria, 45 men tested positive for M343 (R1b). Of these 45, 25 tested positive for U106/S21, and 9 for U152/S28. 8 Men could not be further identified in the study. One man testing positive for U106 also tested positive for U198[49]. Myres et al. report this clade "is most frequent (20-44%) in Switzerland, Italy, France and Western Poland, with additional instances exceeeding 15% in some regions of England and Germany".[24]

R1b1b2a1a2e

This subclade is defined by the presence of the marker S68, also known as L165.

R1b1b2a1a2f

This subclade is defined by the presence of the marker L21, also referred to as M529.[2] Myres et al. report it is most common in England and Ireland (25-50% of the whole male population).[6]

R1b1b2a1a2f2

This subclade within R-L21 is defined by the presence of the marker M222. It is particularly associated with male lines which are Irish or Scottish. In this case, the relatively high frequency of this specific subclade among the population of certain counties in northwestern Ireland may be due to positive social selection, as it is suggested to have been the Y-chromosome haplogroup of the Uí Néill dynastic kindred of ancient Ireland.[28] However it is not restricted to the Uí Néill as it is also associated with the closely related Connachta dynasties, called the Uí Briúin and Uí Fiachrach.[50] M222 is also found as a substantial proportion of the population of Scotland which may indicate substantial settlement from northern Ireland or at least links to it.[28][51] Those areas settled by large numbers of Irish and Scottish emigrants such as North America have a substantial percentage of M222.[28]

R1b1b2a1a2f4

This subclade 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.[52]

Bryan Sykes, in his book Blood of the Isles, gives the populations associated with R1b the name of Oisín for a clan patriarch, much as he did for mitochondrial haplogroups in The Seven Daughters of Eve.

Stephen Oppenheimer also deals with this haplogroup in his book Origins of the British, giving the R1b clan patriarch the Basque name "Ruisko" in honour of what he thought was the Iberian origin of R1b.
