Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread among modern populations.

Some descendant subclades have been found since pre-history in Europe, Central Asia and South Asia. Others have long been present, at lower levels, in parts of West Asia and Africa. Some authorities have also suggested, more controversially, that R-M207 has long been present among Native Americans in North America – a theory that has not yet been widely accepted.[5]

According to geneticist Spencer Wells, haplogroup K originated in the Middle East or Central Asia.[6] However, Karafet et al. (2014) proposed that "rapid diversification ... of K-M526", also known as K2, likely occurred in Southeast Asia (near Indonesia) and later expanded to mainland Asia, although they could not rule out that it might have arisen in Eurasia and later went extinct there, and that either of these scenarios are "equally parsimonious".[7] According to Bergstorm et al, haplogroup K2b1 (Y-haplogroup S/M) found in Indigenous Australians and ancestors of haplogroup R and Q (Y-haplogroup K2b2/root P) split in Southeast Asia near Sahul.[8]

## Origins

[edit]

Geneticist Spencer Wells suggests that haplogroup K likely originated in the Middle East or Central Asia, perhaps in the region of Iran or Pakistan.[6] According to Bergstorm et al, deep-rooted haplogroup K2b1 (Y-haplogroup S/M) found in Indigenous Australians and ancestors of haplogroup R and Q (Y-haplogroup K2b2/root P) split in Southeast Asia near Sahul.[8] Haplogroup P1 may have emerged in Southeast Asia, however according to Karafet, et al. this hypothesis is "parsimonious" and it is just as likely that it originated elsewhere in Eurasia.[7] The SNP M207, which defines Haplogroup R, is believed to have arisen during the Upper Paleolithic era, about 27,000 years ago.[2][1]

Remains of the Mal'ta boy (MA-1) with tomb artifacts, Hermitage Museum, Saint-Petersburg.[9]

Only one confirmed example of basal R* has been found, in 24,000-year-old remains, known as MA1, found at Mal'ta–Buret' culture near Lake Baikal in Siberia.[2] (While a living example of R-M207(xM17,M124) was reported in 2012, it was not tested for the SNP M478; the male concerned – among a sample of 158 ethnic Tajik males from Badakshan, Afghanistan – may therefore belong to R2.)

It is possible that neither of the primary branches of R-M207, namely R1 (R-M173) and R2 (R-M479) still exist in their basal, original forms, i.e. R1* and R2*. No confirmed case, either living or dead, has been reported in scientific literature. (Although in the case of R2*, relatively little research has been completed.)

Despite the rarity of R* and R1*, the relatively rapid expansion – geographically and numerically – of subclades from R1 in particular, has often been noted: "both R1a and R1b comprise young, star-like expansions" (Karafet 2008).

The wide geographical distribution of R1b, in particular, has also been noted. Hallast et al. (2014) mentioned that living examples found in Central Asia included:

* the "deepest subclade" of R-M269 (R1b1a1a2) – the most numerous branch of R1b in Western Europe, and;
* the rare subclade R-PH155 (R1b1b) found only in one Bhutanese individual and one Tajik.

(While Hallast et al. suggested that R-PH155 was "almost as old as the R1a/R1b split", R-PH155 was later discovered to be a subclade of R-L278 (R1b1) and has been given the phylogenetic name R1b1b.)

## Distribution

[edit]

Y-haplogroup R-M207 is common throughout Europe, South Asia and Central Asia (Kayser 2003). It also occurs in the Caucasus and Siberia. Some minorities in Africa also carry subclades of R-M207 at high frequencies.

Proposed migration routes of Haplogroup P among others.[10]

While some indigenous peoples of The Americas and Australasia also feature high levels of R-M207, it is unclear whether these are deep-rooted, or an effect of European colonisation during the early modern era.

### R (R-M207)

[edit]

Haplogroup R* Y-DNA (xR1,R2) was found in 24,000-year-old remains from Mal'ta in Siberia near Lake Baikal.[11] In 2013, R-M207 was found in one out of 132 males from the Kyrgyz people of East Kyrgyzstan.[12]

### R1 (R-M173)

[edit]

Main article: Haplogroup R1

There are many downstream mutations of haplogroup R.(Semino 2000 and Rosser 2000).

Initially, there was debate about the origin of haplogroup R1b in Native Americans. Two early studies suggested that this haplogroup could have been one of the founding Siberian lineages of Native Americans, however this is now considered unlikely, because the R1b lineages commonly found in Native Americans are in most cases identical to those in western Europeans, and its highest concentration is found among a variety of culturally unaffiliated tribes, in eastern North America.[13]

Thus, according to several authors, R1b was most likely introduced through admixture during the post-1492 European settlement of North America.[14][15][16]

### R2 (R-M479)

[edit]

Main article: Haplogroup R2

Haplogroup R-M479 is defined by the presence of the marker M479. The paragroup for the R-M479 lineage is found predominantly in South Asia, although deep-rooted examples have also been found among Portuguese, Spanish, Tatar (Bashkortostan, Russia), and Ossetian (Caucasus) populations (Myres 2010).

One rare subclade may occur only among Ashkenazi Jews, possibly as a result of a founder effect.

"In most cases, there is widespread agreement about whether a particular haplogroup represents an ancient Native American lineage or post-1492 admixture, but the status of haplogroup R-M173 has recently been subject to some debate. Some authors have argued that this haplogroup represents a founding Native American lineage (Lell et al. 2002; Bortolini et al. 2003), whereas others suggest that it instead reflects recent European admixture (Tarazona-Santos and Santos 2002; Bosch et al. 2003; Zegura et al. 2004). In eastern North America, the pattern of haplotype variation within this haplogroup supports the latter hypothesis: R-M173 haplotypes do not cluster by population or culture area, as haplotypes in the other founding haplogroups do, and most match or are closely related to R-M173 haplotypes that are common in Europe but rare in Asia. This pattern is opposite than expected if the Native American R-M173 haplotypes were descended from Asian haplotypes and suggests that recent European admixture is responsible for the presence of haplogroup R-M173 in eastern North America."
