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 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.

Origins

Semino et al. (2004) suggested an origin in East Africa stating: "Both phylogeography and microsatellite variance suggest that E-P2 and its derivative, E-M35, probably originated in eastern Africa." [2]

Trombetta et al. (2011) would also suggested an origin in East Africa:

The new topology here reported has important implications as to the origins of the haplogroup E-P2. Using the principle of the phylogeographic parsimony, the resolution of the E-M215 trifurcation in favor of a common ancestor of E-M2 and E-M329 strongly supports the hypothesis that haplogroup E-P2 originated in eastern Africa, as previously suggested, and that chromosomes E-M2, so frequently observed in sub-Saharan Africa, trace their descent to a common ancestor present in eastern Africa. [3]

Ancient DNA

A sample from the Natufian remains were found to have carried haplogroup E1b1 (1/5; 20%). [4]

At Mota Cave, in Ethiopia, the remains of an ancient Ethiopian male, which was dated to 4500 BP, carried paternal haplogroup E1b1 and maternal haplogroup L3x2a. [5] [6]

E-P2 is now found mostly in Africa, mainly in the form of its predominant subclades E-M215 and E-V38. E-M215 is more common in Northern Africa and the Horn of Africa, and is also found at lower frequencies in the Middle East, Europe and Southern Africa. E-V38 is more common in West Africa, Central Africa, Southern Africa and the African Great Lakes, and occurs at lower frequencies in North Africa and Middle East.

The paraclade, referred to as E-P2*, and including cases which are neither in E-V38 or E-M215 are either rare or nonexistent, and so far none have been found. [3]

Semino et al. (2004) found E-P2 (xM35,xM2) in 10.4% of 48 Ethiopian Amhara, 12.8% of 78 Ethiopian Oromo, 1.9% of 53 South African Bantu, and 2.9% of 139 Senegalese. [8]

Wood et al. (2005) have reported finding E-P2(xP1, xM35) in 11% (1/9) of a sample of Oromo from Ethiopia, 11% (1/9) of a sample of Iraqw from Tanzania, 10% (2/20) of a mixed sample of speakers of various South Semitic languages from Ethiopia, 6% (1/18) of a sample of Amhara from Ethiopia, 3% (1/30) of a sample of Ewe from Ghana, 3% (1/32) of a sample of Fante from Ghana, and 3% (1/34) of a sample of Wolof from Gambia/Senegal. [9]

Stefflova et al. (2009) reported one individual out of a sample of 199 African American men from Philadelphia with E-P2 (xM35, xM2). [10]

Cruciani et al. (2002) found E-P2 (xM35, xM2) in: 18% of 22 Ethiopian Jews, 2% of 49 Mossi from Burkina Faso, 3% of 37 Rimaibe also from Burkina Faso, and 6% of 17 Fulbe from Cameroon. [11]

Semino et al. (2002) found E-P2 (xM35, xM2) in 18.2% of 88 Ethiopians. [12] [13]

Moran et al. (2004) found E-P2 (xM35, xM2) in Ethiopian athletes and control groups and reported the following results; General control: 4%(4/95), Arsi control: 8%(7/85), 5-10K: 22%(5/23) and Track and Field: 11%(2/11). [14]

Phylogenetics

Phylogenetic history

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.

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.

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.

<span class="mw-page-title-main">Human Y-chromosome DNA haplogroup</span> Human DNA groupings

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.

<span class="mw-page-title-main">Haplogroup R (Y-DNA)</span> Human Y-chromosome DNA haplogroup

<span class="mw-page-title-main">Haplogroup CT</span> Human Y chromosome DNA grouping indicating common ancestry

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.

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.

In human genetics, Y Haplogroup E-M123 is a Y-chromosome haplogroup, and defined by the single nucleotide polymorphism (SNP) mutation M123. Like its closest relatives within the larger E-M215 haplogroup, E-M123 is found in Asia, Europe and Africa.

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*.

<span class="mw-page-title-main">Haplogroup E-M329</span> Human Y-chromosome DNA haplogroup

Haplogroup E-M329, also known as E1b1a2, is a human Y-chromosome DNA haplogroup. E-M329 is mostly found in East Africa.

<span class="mw-page-title-main">Haplogroup E-M2</span> Human Y-chromosome DNA haplogroup

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.
