Haplogroup E-M96 is a human Y-chromosome DNA haplogroup. It is one of the two main branches of the older and ancestral haplogroup DE, the other main branch being haplogroup D. The E-M96 clade is divided into two main subclades: the more common E-P147, and the less common E-M75.
Underhill (2001) proposed that haplogroup E may have arisen in East Africa. [10] Some authors as Chandrasekar (2007), accept the earlier position of Hammer (1997) that Haplogroup E may have originated in West Asia, [11] given that:
However, several discoveries made since the Hammer articles are thought to make an Asian origin less likely:
Kohl et al. (2009) presumed a West African origin for haplogroup E, stating: "From the 20 main haplogroups in the Y-chromosomal haplogroup tree, only 5 were detected in the analysed Amharic population in Ethiopia. Haplogroup A is near the roots of the tree and is only found among males on the African continent. The major haplogroup detected was E. Haplogroup E has its origin in West Africa. Due to immigration haplogroup A, which originally dominated in Ethiopia, has been partly replaced." [7]
In 2015, Poznik & Underhill et al. claimed haplogroup E arose outside Africa, arguing that, "This model of geographical segregation within the CT clade requires just one continental haplogroup exchange (E to Africa), rather than three (D, C, and F out of Africa). The timing of this putative return to Africa, between the emergence of haplogroup E and its differentiation within Africa by 58 kya, is consistent with proposals, based on non–Y chromosome data, of abundant gene flow between Africa and Arabia 50–80 kya." [8]
In 2015, Trobetta et al. suggested an East African origin for haplogroup E, stating: "our phylogeographic analysis, based on thousands of samples worldwide, suggests that the radiation of haplogroup E started about 58 ka, somewhere in sub-Saharan Africa, with a higher posterior probability (0.73) for an eastern African origin." [6]
Cabrera et al. (2018) hypothesizes a Eurasian center of origin and dispersal for haplogroup E based on the similar age of the clade's parent haplogroup DE and the mtDNA haplogroup L3. According to this hypothesis, after an initial Out-of-Africa migration of early anatomically modern humans around 125 kya, haplogroup DE diversified around the Himalayas and in or westward of the Tibet, after which E-carrying males are proposed to have back-migrated from the paternal haplogroup's place of origin in Eurasia around 70 kya along with females bearing the maternal haplogroup L3, which the study also hypothesizes to have originated in Eurasia, into Africa. These new Eurasian lineages were then suggested to have largely replaced the old autochthonous male (such as haplogroup B-M60) and female African lineages. [9]
Haber et al. (2019) study proposed an African origin for haplogroup E based on an analysis of the Y-chromosomal phylogenetic structure, haplogroup divergence times, and the recently discovered haplogroup D0 found in three Nigerians, an additional branch of the DE lineage diverging early from haplogroup D. The authors support an African origin for haplogroup DE, and the immigration of haplogroups C, D and FT out of Africa around 50,300–81,000 ybp. The early divergence dates found in the study for DE, E, and D0 (all dated to about 71-76 kya), which are determined to predate the migration out-of-Africa of the ancestors of Eurasians (dated to ca. 50-60 kya), are also considered by the authors to support an African origin for those haplogroups. [3]
Pre-Pottery Neolithic B remains from the Levant were found to have carried haplogroup E (1/7; ~14%). [14]
At Nyarindi Rockshelter, in Kenya, there were two individuals, dated to the Later Stone Age (3500 BP); one carried haplogroup L4b2a and another carried haplogroup E (E-M96, E-P162). [15] [16]
At Kindoki, in the Democratic Republic of Congo, there were three individuals, dated to the protohistoric period (230 BP, 150 BP, 230 BP); one carried haplogroups E1b1a1a1d1a2 (E-CTS99, E-CTS99) and L1c3a1b, another carried haplogroup E (E-M96, E-PF1620), and the last carried haplogroups R1b1 (R-P25 1, R-M415) and L0a1b1a1. [15] [16]
Most members of haplogroup E-M96 belong to E1, while haplogroup E2-M75 is rare. Haplogroup E1a is split into two main branches: E1a1 (E-M44) which has been mostly found in Europe, West Asia and among Ashkenazi Jews; and E1a2 (E-Z958) which has been exclusively identified in Sub-Saharan Africa. [17] Haplogroup E-M2 is the most prevalent subclade of E in Sub-Saharan Africa and is strongly associated with expansion of Bantu speakers.
E-M215 is found at high frequencies in North Africa, West Asia, East Africa and Europe. E-M215 is most common among Afro-Asiatic speakers in the Near East, North Africa and the Horn of Africa, and it has also been reported among some Nilo-Saharan and Niger–Congo speakers in North East Africa and Sudan. E-M215 is far less common in West, Central, and Southern Africa, though it has been observed among some Khoisan speakers [18] and among Niger–Congo speakers in Senegambia, [19] Guinea-Bissau, [20] Burkina Faso, [21] Ghana, Gabon, [22] the Democratic Republic of the Congo, Rwanda, [23] Namibia, and South Africa.
Paragroup E-M96* refers to lineages belonging to the E clade but which cannot be classified into any known branch. E(xE1-P147, E2-M75) - that is, E which has tested negative for both P147 and M75 - has been reported in 3 males from Lebanon, [24] 2 Amharas from Ethiopia, [25] 2 males from Syria, [26] 2 males from Saudi Arabia, [27] and in a single Bantu-speaking male from South Africa. [13] E(xE1a-M33, E1b1-P2, E2-M75) was reported among several Southern African populations and in an Egyptian man; [28] E(xE1a-M33, E1b1a1-M2, E1b1b-M215, E2-M75) has also been observed amongst pygmies and Bantu from Cameroon and Gabon; [22] and also in Burkina Faso [29] and a Fulbe man from Niger. [30]
Recently it was discovered that 3 East African men previously classified only as E*-M96 could be assigned to a new branch, E-V44, which is a sister branch to E1-P147; E-P147 and E-V44 share the V3725 mutation, making E2-M75 and E-V3725 the two known primary branches of E. [31] Two Saudi private testers from Mecca and Jizan were also found to belong to this elusive and rare branch. [32] It is not known whether or not some (or all) other E*(xE1,E2) in previous studies would fall into V44 as well.
E-P147 (also known as E1) is by far the most numerous and widely distributed branch of E-M96. It has two primary branches: E-M132 (E1a) and E-P177 (E1b). Haplogroup E1a is split into two branches: E1a1 (E-M44) which has been mostly found in Europe, West Asia and among Ashkenazi Jews; and E1a2 (E-Z958) which has been exclusively identified in Sub-Saharan Africa. [33]
Haplogroup E-P2 (E1b1) is the most frequent variant of E-M96 and the most common Y-DNA lineage in Africa with two main descendants: E-V38 (E1b1a) and E-M215 (E1b1b). Haplogroup E (xE3b,E3a) - that is, E tested negative for both M35 and M2, has been reported in 11 males from Morocco in Zalloua et al. (2008b). [34]
Haplogroup E-V38 is the ancestor of E-M2 (E1b1a1) which is the most common subclade of E in the entirety of Sub-Saharan Africa, and is strongly associated with the expansion of Bantu speakers throughout Central and Southern Africa. Another descendant of E-V38, E-M329 (E1b1a2), has been observed in an Ethiopian hunter-gatherer from 4,200 ybp, and is mostly found in males from the Horn of Africa and Arabian Peninsula. [35]
On the other hand, haplogroup E-M215 (E1b1b) is distributed in high frequencies throughout North Africa, Western Asia, East Africa and Europe. Haplogroup E-Z827 was found in Natufian samples (E-Z830+) dated to 10,000 ybp from Palestine, and is commonly found throughout West Asia, North Africa, Europe and Ethiopia. Haplogroup E-V68 is also commonly observed in North Africa and West Asia, and has been found in Iberomaurusian remains dating to 15,000 ybp from Morocco, with its prolific downstream descendant E-V32 dominating male lineages in Horn of Africa.
E-M75 (also known as E2) is present throughout Subequatorial Africa, particularly in the African Great Lakes and Central Africa. The highest concentration of the haplogroup has been found among the Alur (66.67%), [28] Hema (38.89%), [28] Rimaibe (27.03%), [21] Mbuti (25.00%), [21] Daba (22.22%), [21] Eviya (20.83%), [22] Zulu (20.69%), [28] and Kenyan Bantus (17.24%). [23]
Haplogroup E-M75(xM41,M54) has been found in 6% (1/18) of Dama from Namibia, [28] 4% (1/26) of Ganda from Uganda, [28] 3% (1/39) of Mandinka from Gambia/Senegal, [28] and 2% (1/49) of Sena from Mozambique . [28]
Private commercial DNA testing at Family Tree DNA shows numerous E-M75 males originating from the Arabian Peninsula (Saudi Arabia, Bahrain, Kuwait, Yemen, and the United Arab Emirates), and among Ashkenazi Jews. [36] E-M75 has also been identified in a Lebanese male. [37]
Prior to 2002, there were in academic literature at least seven naming systems for the Y-Chromosome Phylogenetic tree. This led to considerable confusion. In 2002, the major research groups came together and formed the Y-Chromosome Consortium (YCC). They published a joint paper that created a single new tree that all agreed to use. Later, a group of citizen scientists with an interest in population genetics and genetic genealogy formed a working group to create an amateur tree aiming at being above all timely. The table below brings together all of these works at the point of the landmark 2002 YCC Tree. This allows a researcher reviewing older published literature to quickly move between nomenclatures.

The following research teams per their publications were represented in the creation of the YCC tree.
This phylogenetic tree of haplogroup subclades is based on the Y-Chromosome Consortium (YCC) Tree, [38] the ISOGG Y-DNA Haplogroup Tree, [39] and subsequent published research.
Haplogroup J-M304, also known as J, is a human Y-chromosome DNA haplogroup. It is believed to have evolved in Western Asia. The clade spread from there during the Neolithic, primarily into North Africa, the Horn of Africa, the Socotra Archipelago, the Caucasus, Europe, Anatolia, Central Asia, South Asia, and Southeast Asia.
E-M215 or E1b1b, formerly known as E3b, is a major human Y-chromosome DNA haplogroup. E-M215 has two basal branches, E-M35 and E-M281. E-M35 is primarily distributed in North Africa and the Horn of Africa, and occurs at moderate frequencies in the Middle East, Europe, and Southern Africa. E-M281 occurs at a low frequency in Ethiopia.
Haplogroup A is a human Y-chromosome DNA haplogroup, which includes all living human Y chromosomes. Bearers of extant sub-clades of haplogroup A are almost exclusively found in Africa, in contrast with haplogroup BT, bearers of which participated in the Out of Africa migration of early modern humans. The known branches of haplogroup A are A00, A0, A1a, and A1b1; these branches are only very distantly related, and are not more closely related to each other than they are to haplogroup BT.
Haplogroup E-V38, also known as E1b1a-V38, is a major human Y-chromosome DNA haplogroup. E-V38 is primarily distributed in Africa. E-V38 has two basal branches, E-M329 and E-M2. E-M329 is a subclade mostly found in East Africa. E-M2 is the predominant subclade in West Africa, Central Africa, Southern Africa, and the region of African Great Lakes; it also occurs at moderate frequencies in North Africa, West Asia, and Southern Europe.
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). The Y-chromosome accumulates approximately two mutations per generation, and Y-DNA haplogroups represent significant branches of the Y-chromosome phylogenetic tree, each characterized by hundreds or even thousands of unique mutations.
Haplogroup DE is a human Y-chromosome DNA haplogroup. It is defined by the single nucleotide polymorphism (SNP) mutations, or UEPs, M1(YAP), M145(P205), M203, P144, P153, P165, P167, P183. DE is unique because it is distributed in several geographically distinct clusters. An immediate subclade, haplogroup D, is mainly found in East Asia, parts of Central Asia, and the Andaman Islands, but also sporadically in West Africa and West Asia. The other immediate subclade, haplogroup E, is common in Africa, and to a lesser extent the Middle East and southern Europe.
Haplogroup CT is a human Y chromosome haplogroup. CT has two basal branches, CF and DE. DE is divided into a predominantly Asia-distributed haplogroup D-CTS3946 and a predominantly Africa-distributed haplogroup E-M96, while CF is divided into an East Asian, Native American, and Oceanian haplogroup C-M130 and haplogroup F-M89, which dominates most non-African populations.
E-M35, also known as E1b1b1-M35, is a human Y-chromosome DNA haplogroup. E-M35 has two basal branches, E-V68 and E-Z827. E-V68 and E-Z827 are primarily distributed in North Africa and the Horn of Africa, and occur at lower frequencies in the Middle East, Europe, and Southern Africa.
Haplogroup E-P147 is a human Y-chromosome DNA haplogroup. Haplogroup E-P147, along with the less common haplogroup E-M75, is one of the two main branches of the older haplogroup E-M96. The E-P147 clade is commonly observed throughout Africa and is divided into two subclades: the less common, haplogroup E-M132, and the more common, haplogroup E-P177.
Haplogroup E-M132, formerly known as E-M33 (E1a), is a human Y-chromosome DNA haplogroup. Along with E-P177, it is one of the two main branches of the older E-P147 paternal clade. E-M132 is divided into two primary sub-branches, E-M44 and E-Z958, with many descendant subclades.
Haplogroup E-P177 is a human Y-chromosome DNA haplogroup. E-P177 has two known subclades, which are haplogroup E-P2 and haplogroup E-P75.
Haplogroup E-M75 is a human Y-chromosome DNA haplogroup. Along with haplogroup E-P147, it is one of the two main branches of the older haplogroup E-M96.
Haplogroup E-V68, also known as E1b1b1a, is a major human Y-chromosome DNA haplogroup found in North Africa, the Horn of Africa, Western Asia and Europe. It is a subclade of the larger and older haplogroup, known as E1b1b or E-M215. The E1b1b1a lineage is identified by the presence of a single nucleotide polymorphism (SNP) mutation on the Y chromosome, which is known as V68. It is a subject of discussion and study in genetics as well as genetic genealogy, archaeology, and historical linguistics.
Haplogroup E-P2, also known as E1b1, is a human Y-chromosome DNA haplogroup. E-P2 has two basal branches, E-V38 and E-M215. E-P2 had an ancient presence in East Africa and the Levant; presently, it is primarily distributed in Africa where it may have originated, and occurs at lower frequencies in the Middle East and Europe.
In human population genetics, Y-Chromosome haplogroups define the major lineages of direct paternal (male) lines back to a shared common ancestor in Africa. Men in the same haplogroup share a set of differences, or markers, on their Y-Chromosome, which distinguish them from men in other haplogroups. These UEPs, or markers used to define haplogroups, are SNP mutations. Y-Chromosome Haplogroups all form "family trees" or "phylogenies", with both branches or sub-clades diverging from a common haplogroup ancestor, and also with all haplogroups themselves linked into one family tree which traces back ultimately to the most recent shared male line ancestor of all men alive today, called in popular science Y Chromosome Adam.
E-Z827, also known as E1b1b1b, is a major human Y-chromosome DNA haplogroup. It is the parent lineage to the E-Z830 and E-V257 subclades, and defines their common phylogeny. The former is predominantly found in the Middle East; the latter is most frequently observed in North Africa, with its E-M81 subclade observed among the ancient Guanche natives of the Canary Islands. E-Z827 is also found at lower frequencies in Europe, and in isolated parts of Southeast Africa.
Moroccan genetics encompasses the genetic history of the people of Morocco, and the genetic influence of this ancestry on world populations. It has been heavily influenced by geography.
Haplogroup A-L1085, also known as haplogroup A0-T is a human Y-DNA haplogroup. It is part of the paternal lineage of almost all humans alive today. The SNP L1085 has played two roles in population genetics: firstly, most Y-DNA haplogroups have diverged from it and; secondly, it defines the undiverged basal clade A-L1085*.
Haplogroup E-M329, also known as E1b1a2, is a human Y-chromosome DNA haplogroup. E-M329 is mostly found in East Africa.
Haplogroup E-M2, also known as E1b1a1-M2, is a human Y-chromosome DNA haplogroup. E-M2 is primarily distributed within Africa followed by West Asia. More specifically, E-M2 is the predominant subclade in West Africa, Central Africa, Southern Africa, and the region of the African Great Lakes; it also occurs at moderate frequencies in North Africa, and the Middle East. E-M2 has several subclades, but many of these subhaplogroups are included in either E-L485 or E-U175. E-M2 is especially common among indigenous Africans who speak Niger-Congo languages, and was spread to Southern Africa and East Africa through the Bantu expansion.
