In Genetic genealogy and human genetics, Y DNA haplogroup J-M267, also commonly known as Haplogroup J1 is a subclade (branch) of Y-DNA haplogroup J-P209, (commonly known as Haplogroup J) along with its sibling clade Y DNA haplogroup J-M172 (commonly known as Haplogroup J2). (All these haplogroups have had other historical names listed below.[Phylogenetics 1][Phylogenetics 2])
Men from this lineage share a common paternal ancestor, which is demonstrated and defined by the presence of the SNP mutation referred to as M267, which was announced in (Cinnioğlu 2004). This haplogroup is found today in significant frequencies in many areas in or near the Middle East, and parts of the Caucasus, Sudan and Ethiopia. It is also found in high frequencies in parts of North Africa, Southern Europe, and amongst Jewish groups, especially those with Cohen surnames. It can also be found much less commonly, but still occasionally in significant amounts, throughout Europe and as far east as Central Asia and the Indian Subcontinent.

Since the discovery of haplogroup J-P209 it has generally been recognized that it shows signs of having originated in or near West Asia. The frequency and diversity of both its major branches, J-M267 and J-M172, in that region makes them candidates as genetic markers of the spread of farming technology during the Neolithic, which is proposed to have had a major impact upon human populations.
J-M267 has several recognized subclades, some of which were recognized before J-M267 itself was recognized, for example J-M62 Y Chromosome Consortium "YCC" 2002. With one notable exception, J-P58, most of these are not common (Tofanelli 2009). Because of the dominance of J-P58 in J-M267 populations in many areas, discussion of J-M267's origins require a discussion of J-P58 at the same time.
North Africa and Horn of Africa
North Africa received Semitic migrations, according to some studies it may have been diffused in recent time by Arabs who, mainly from the 7th century a.d., expanded to northern Africa (Arredi 2004 and Semino 2004). However the Canary islands is not known to have had any Semitic language. There J-M267 is dominated by J-P58, and dispersed in a very uneven manner according to studies so far, often but not always being lower among Berber and/or non-urban populations. In Ethiopia there are signs of older movements of J-M267 into Africa across the Red Sea, not only in the J-P58 form. This also appears to be associated with Semitic languages. According to a study in 2011, in Tunisia, J-M267 is significantly more abundant in the urban (31.3%) than in the rural total population (2.5%). According to the authors, these results could be explained by supposing that Arabization in Tunisia was a military enterprise, therefore, mainly driven by men that displaced native Berbers to geographically marginal areas but they frequently married Berber women (Ennafaa 2011).

The P58 marker which defines subgroup J1c3 was announced in (Karafet 2008), but had been announced earlier under the name Page08 in (Repping 2006 and called that again in Chiaroni 2011). It is very prevalent in many areas where J-M267 is common, especially in parts of North Africa and throughout the Arabian peninsula. It also makes up approximately 70% of the J-M267 among the Amhara of Ethiopia. Notably, it is not common among the J-M267.
Chiaroni 2009 proposed that J-P58 (that they refer to as J1e) might have first dispersed during the Pre-Pottery Neolithic B period, "from a geographical zone, including northeast Syria, northern Iraq and eastern Turkey toward Mediterranean Anatolia, Ismaili from southern Syria, Jordan, Palestine and northern Egypt." They further propose that the Zarzian material culture may be ancestral. They also propose that this movement of people may also be linked to the dispersal of Semitic languages by hunter-herders, who moved into arid areas during periods known to have had low rainfall. Thus, while other haplogroups including J-M267 moved out of the area with agriculturalists who followed the rainfall, populations carrying J-M267 remained with their flocks (King 2002 and Chiaroni 2008).
According to this scenario, after the initial neolithic expansion involving Semitic languages, which possibly reached as far as Yemen, a more recent dispersal occurred during the Chalcolithic or Early Bronze Age (approximately 3000–5000 BCE), and this involved the branch of Semitic which leads to the Arabic language. The authors propose that this involved a spread of some J-P58 from the direction of Syria towards Arab populations of the Arabian Peninsula and Negev.
On the other hand, the authors agree that later waves of dispersion in and around this area have also had complex effects upon the distributions of some types of J-P58 in some regions. They list three regions which are particularly important to their proposal:
- The Levant (Syria, Jordan, Israel and Palestine). In this area, Chiaroni 2009 note a "patchy distribution of J1c3 or J-P58 frequency" which is difficult to interpret, and which "may reflect the complex demographic dynamics of religion and ethnicity in the region".
- The northern area of eastern Anatolia, northern Iraq and northwest Iran. In this area, Chiaroni 2009 recognize signs that J-M267 might have an older presence, and on balance they accept the evidence but note that it could be in error.
- The southern area of Oman, Yemen and Ethiopia. In this area, Chiaroni 2009 recognize similar signs, but reject it as possible a result of "either sampling variability and/or demographic complexity associated with multiple founders and multiple migrations."
The "YCAII=22-22 and DYS388≥15" cluster
Not only is the J-P58 group itself very dominant in many areas where J-M267 or J1 is common, but J-P58 in turn contains a large cluster which had been recognized before the discovery of P58, and is still a subject of research. This relatively young cluster, compared to J-M267 overall, was identified by STR markers haplotypes - specifically YCAII as 22-22, and DYS388 having unusual repeat values of 15 or higher, instead of more typical 13 (Chiaroni 2011) This cluster was found to be relevant in some well-publicized studies of Jewish and Palestinian populations (Nebel 2000 and Hammer 2009). More generally, since then this cluster has been found to be frequent among men in the Middle East and North Africa, but less frequent in areas of Ethiopia and Europe where J-M267 is nevertheless common. The pattern is therefore similar to the pattern of J-P58 generally, described above, and may be caused by the same movements of people (Chiaroni 2009).
Tofanelli 2009 refers to this overall cluster with YCAII=22-22 and high DYS388 values as an "Arabic" as opposed to a "Eurasian" type of J-M267. This Arabic type includes Arabic speakers from Maghreb, Sudan, Iraq and Qatar, and it is a relatively homogeneous group, implying that it might have dispersed relatively recently compared to J-M267 generally. The more diverse "Eurasian" group includes Europeans, Kurds, Iranians and Ethiopians (despite Ethiopia being outside of Eurasia), and is much more diverse. The authors also say that "Omanis show a mix of Eurasian pool-like and typical Arabic haplotypes as expected, considering the role of corridor played at different times by the Gulf of Oman in the dispersal of Asian and East African genes." Chiaroni 2009 also noted the anomalously high apparent age of Omani J-M267 when looking more generally at J-P58 and J-M267 more generally.
This cluster in turn contains three well-known related sub-clusters. First, it contains the majority of the Jewish "Cohen modal haplotype", found among Jewish populations, but especially in men with surnames related to Cohen. It also contains both the Galilee modal haplotype and Palestinian & Israeli Arab modal haplotype associated with Palestinians and Israeli Arabs by Nebel 2000 and Hammer 2009. Nebel 2002 then pointed out that the Galilee modal is also the most frequent type of J-P209 haplotype found in northwest Africans, and in Yemen, so it is not isolated to the area of Israel and the Palestine. But notably, this particular variant "is absent from two distinct non-Arab Middle Eastern populations, Jews and Muslim Kurds", even though both these populations do have high levels of J-P209 haplotypes.
Nebel 2002 noted not only the presence of the Galilee modal of J-M267 in the Maghreb but also that J-M267 in this region had very little diversity generally. They concluded that J-M267 in this region "is derived not only from the early Neolithic dispersion but also from recent expansions from the Arabian peninsula" proposing that they might have been carried from the Middle East with the Arab expansion in the seventh century AD. Semino 2004 later agreed that this seemed consistent with the evidence and generalized from this that distribution of the entire YCAII=22-22 cluster of J-M267 in the Arabic speaking areas of the Middle East and North Africa might in fact mainly have an origin in historical times.
More recent studies have emphasized doubt that the Islamic expansions are old enough to completely explain the major patterns of J-M267 frequencies. Chiaroni 2009 rejected this for J-P58 as a whole, but accepted that "some of the populations with low diversity, such as Bedouins from Israel, Qatar, Sudan and UAE, are tightly clustered near high-frequency haplotypes suggesting founder effects with star burst expansion in the Arabian Desert". They did not comment on the Maghreb.
Tofanelli 2009 take a stronger position of rejecting any strong correlation between the Arab expansion and either the YCAII=22-22 STR-defined sub-cluster as discussed by Semino 2004 or the smaller "Galilee modal" as discussed by (Nebel 2002). They also estimate that the Cohen modal haplotype must be older than 4500 years old, and maybe as much as 8600 years old - well before the supposed origin of the Cohanim. Only the so-called Palestinian & Israeli Arab modal had a strong correlation to an ethnic group, but it was also rare. In conclusion, the authors were negative about the usefulness of STR defined modals for any "forensic or genealogical purposes" because "they were found across ethnic groups with different cultural or geographic affiliation".
Hammer 2009 disagreed, at least concerning the Cohen modal haplotype. They said that it was necessary to look at a more detailed STR haplotype in order to define a new "Extended Cohen Modal Haplotype" which is extremely rare outside Jewish populations, and even within Jewish populations is mainly only found in Cohanim. They also said that by using more markers and a more restrictive definition, the estimated age of the Cohanim lineage is lower than the estimates of Tofanelli 2009, and it is consistent with a common ancestor at the approximate time of founding of the priesthood which is the source of Cohen surnames.
The correspondence between P58 and high DYS388 values, and YCAII=22-22 is not perfect. For example the J-M267 subclade of J-P58 defined by SNP M368 has DYS388=13 and YCAII=19-22, like other types of J-M267 outside the "Arabic" type of J-M267, and it is therefore believed to be a relatively old offshoot of J-P58, that did not take part in the most recent waves of J-M267 expansion in the Middle East (Chiaroni 2009). These DYS388=13 haplotypes are most common in the Caucasus and Anatolia, but also found in Ethiopia (Tofanelli 2009).
