In human genetics, E-V68, is a major Y chromosome haplogroup found in Africa, Western Asia and Europe, and is in turn part of the larger haplogroup known as E-M35. It is identified by the presence of a single nucleotide polymorphism (SNP) mutation on the Y chromosome known as V68. It is a subject of discussion and study in genetics as well as genetic genealogy, archaeology, and historical linguistics.

E-V68 is dominated by its longer-known subclade E-M78. In various publications, both E-V68 and E-M78 have been referred to by other names, especially phylogenetic names such as "E3b1a" which are designed to show their place on the family tree of all humans. These various names change as new discoveries are made and are discussed below.

Origins

E-M78, like its parent clade E-V68, is thought to have an African origin. Based on genetic STR variance data, Cruciani et al. (2007) suggests that this subclade originated in "Northeastern Africa", which in the study refers specifically to the region of Egypt and Libya.^[3]

Prior to Cruciani et al. (2007), Semino et al. (2004) had proposed a place of origin for E-M78 further south in East Africa. This was because of the high frequency and diversity of E-M78 lineages in the region of Ethiopia. However, Cruciani et al. (2007) were able to study more data, and concluded that the E-M78 lineages in the Horn of Africa were dominated by relatively recent branches (see E-V32 below). They concluded that the region of Egypt was the likely place of origin of E-M78 based on "the peripheral geographic distribution of the most derived subhaplogroups with respect to northeastern Africa, as well as the results of quantitative analysis of UEP and microsatellite diversity".

Cruciani et al. (2007) also note this as evidence for "a corridor for bidirectional migrations" between Northeast Africa (Egypt and Libya in their data) on the one hand and East Africa on the other. Because Cruciani et al. (2007) also proposed that E-M35, the parent clade of E-M78, originated in East Africa during the paleolithic and subsequently spread to the region of Egypt. E-M78 in East Africa, is therefore the result of a back migration. The authors believe there were "at least 2 episodes between 23.9–17.3 ky and 18.0–5.9 ky ago".

Another probable migration to the south from Egypt was noted by Hassan et al. (2008) based upon their survey of Sudan. Specifically E-V12 and E-V22, "might have been brought to Sudan from North Africa after the progressive desertification of the Sahara around 6,000-8,000 years ago".

Northwards from Egypt and Libya, E-M78 migrated into the Middle East, but additionally Trombetta et al. (2011) proposed that the earlier E-V68 carrying population may have migrated by sea directly from Africa to southwestern Europe, because they observed cases of E-V68* (without the M78 mutation) only in Sardinia, and not in the Middle Eastern samples. Concerning E-M78, like other forms of E-V68 there is evidence of multiple routes of expansion out of an African homeland.

On the other hand, while there were apparently direct migrations from North Africa to Iberia and Southern Italy (of people carrying E-V68*, E-V12, E-V22, and E-V65), the majority of E-M78 lineages found in Europe belong to the E-V13 sub-clade which appears to have entered Europe at some time undeterminded from the Near East, where it apparently originated, via the Balkans.

Coming to similar conclusions as the Cruciani and Trombetta team, Battaglia et al. (2008), writing prior to the discovery of E-V68, describe Egypt as "a hub for the distribution of the various geographically localized M78-related sub-clades" and, based on archaeological data, they propose that the point of origin of E-M78 (as opposed to later dispersals from Egypt) may have been in a refugium which "existed on the border of present-day Sudan and Egypt, near Lake Nubia, until the onset of a humid phase around 8500 BC. The northward-moving rainfall belts during this period could have also spurred a rapid migration of Mesolithic foragers northwards in Africa, the Levant and ultimately onwards to Asia Minor and Europe, where they each eventually differentiated into their regionally distinctive branches".

The division of E-V68 into sub-clades such as E-V12, E-V13, etc. has largely been the work of an Italian team including Fulvio Cruciani, Beniamino Trombetta, Rosario Scozzari and others. They started on the basis of STR studies in 2004, and then in 2006 they announced the discoveries of single nucleotide polymorphism (SNP) mutations which could define most of the main branches with better clarity, which was then discussed further in 2007.^[1][4][5] These articles were the basis of the updated phylogenies found in Karafet (2008), and ISOGG, which is in turn the basis of the phylogeny given below.

Age

No separate calculation has been done for the age of E-V68, but as it is approximately identical to E-M78, any approximation of its age is also approximately identical.

The M78 mutation has been estimated to have occurred up to 18,600 years ago (17,300–20,000 years ago), with some possibility that it may have been more recent. Cruciani et al. (2007) use two calculation methods for estimating the age of E-M78 which give very different results. For the main 18,600 years ago, the ASD method is used, while for a second "ρ method", used as a check, gives 13.7kya with a standard deviation of 2.3kya, but the difference between the two methods is only large for the age estimation of E-M78, not its sub-clades. The authors state the big difference is "attributable to the relevant departure from a star-like structure because of repeated founder effects".

Battaglia et al. (2007) estimated that E-M78 (called E1b1b1a1 in that paper) has been in Europe longer than 10,000 years. And more recently, Lacan et al. (2011) found that human remains excavated in a Spanish funeral cave dated to approximately 7000 years ago were in the E-V13 branch of E-M78.

Family tree

This phylogenetic tree of haplogroup subclades is based on the YCC 2008 tree and subsequent published research as summarized by ISOGG in 2013.^[6][7][8]

M521 E-M521 (E1b1b1a1e) Found in two individuals in Greece by Battaglia et al. 2008

Distribution

So far, three individuals who are in E-V68 but not E-M78 have been reported in Sardinia, by Trombetta et al. (2010), when announcing the discovery of V68.

E-M78 is widely distributed in North Africa, Horn of Africa, West Asia (stretching as far as Southern Asia), and Europe.^[1][5]

The most basal and rare E-M78* paragroup has been found at its highest frequencies in Egyptians from the Gurna Oasis (5.88%), with lower frequencies also observed in Moroccan Arabs, Sardinians, the Balkans, and Andalusians from Huelva.^[1][2][9]

The highest frequencies of all the defined E-M78 sub-clades is found amongst populations in the large area stretching from northern Kenya (amongst the Borana people) to Southern Egypt, and including all of the Horn of Africa and most of Sudan.^[4]

Outside of the areas where it is most common in Africa (North Africa and the Horn of Africa), E-V68 is also observed in other parts of Africa, in lower frequencies, for example in Guinea-Bissau, where its presence has been tentatively attributed to trans-Saharan movements of people from North Africa.^[10]

The European distribution, dominated by E-V13 except in Iberia, has a frequency peak centered in parts of the Balkans (approximately 20% in southern areas; up to almost 50% is some particular places and populations^[11][12]) and Italy and declining frequencies evident toward western, central, and northeastern Europe. This is discussed in more detail below.

E-V12

This sub-clade of E-M78 is the one which appears to have split from the others first (it arose c. 13.7-15.2 kya^[1]). According to Cruciani et al. (2007), E-V12 likely originated in North Africa.

Undifferentiated E-V12* lineages

Undifferentiated E-V12* lineages (not E-V32 or E-M224, so therefore named "E-V12*") are found at especially high levels (44.3%) in Southern Egyptians, but also scattered widely in small amounts in both Northern Africa and Europe, but with very little sign in Western Asia, apart from Turkey.^[1] These E-V12* lineages were formerly included (along with many E-V22* lineages^{[Note 1]}) in Cruciani et al.'s original (2004) "delta cluster", which he had defined using Y-STR profiles. With the discovery of the defining SNP, Cruciani et al. (2007) reported that V-12* was found in its highest concentrations in Egypt, especially Southern Egypt. Hassan et al. (2008) report a significant presence of E-V12* in neighboring Sudan, including 5/33 Copts and 5/39 Nubians. E-V12* made up approximately 20% of the Sudanese E-M78. They propose that the E-V12 and E-V22 sub-clades of E-M78 might have been brought to Sudan from their place of origin in North Africa after the progressive desertification of the Sahara around 6,000–8,000 years ago. Sudden climate change might have forced several Neolithic cultures/people to migrate northward to the Mediterranean and southward to the Sahel and the Nile Valley.^[13] The E-V12* paragroup is also observed in Europe (e.g. amongst French Basques) and Eastern Anatolia (e.g. Erzurum Turks).^[1]

Sub-clades of E-V12

E-M224

E-M224 has been found in Israel among Yemeni population (5%) and appears to be a minor subclade.

Its discovery was announced in Underhill et al. (2001) and Shen et al. (2004) found 1 out of their 20 Yemeni Israelis they tested. Cruciani et al. (2006) called M224 "rare and rather uninformative" and they found no exemplars.

Onofri et al. (2006), while testing a new multiplex, claimed to find several M224 examples in both African and European samples.^{[Note 2]}

E-V32

Cruciani et al. (2007) suggest that this sub-clade of E-V12 originated in North Africa, and then subsequently expanded further south into the Horn of Africa, where it is now prevalent.^{[Note 3]} Before the discovery of V32, Cruciani et al. (2004) referred to the same lineages as the "gamma cluster", which was estimated to have arisen about 8,500 years ago. They stated that "the highest frequencies in the three Cushitic-speaking groups: the Borana from Kenya (71.4%), the Oromo from Ethiopia (32.0%), and the Somali (52.2%). Outside of eastern Africa, it was found only in two subjects from Egypt (3.6%) and in one Arab from Morocco". Sanchez et al. (2005) found it extremely prominent in Somali men and stated that "the male Somali population is a branch of the Horn African population – closely related to the Oromos in Ethiopia and North Kenya (Boranas)" and that their gamma cluster lineages "probably were introduced into the Somali population 4000–5000 years ago". More recently, Tillmar et al. (2009) typed 147 males from Somalia for 12 Y-STR loci, and observed that 77% (113/147) had typical E-V32 haplotypes. This is currently the highest frequency of E-V32 found in any single sample population. Similarly, Hassan et al. (2008) in their study observed this to be the most common of the sub-clades of E-M78 found in Sudan, especially among the Beja, Masalit and Fur. The Beja, like Somalis and Oromos, speak an Afro-Asiatic language and live along the "corridor" from the Horn of Africa to Egypt. Hassan et al. (2008) interpret this as reinforcing the "strong correlation between linguistic and genetic diversity" and signs of relatedness between the Beja and the peoples of the Horn of Africa such as the Amhara and Oromo. On the other hand, the Masalit and Fur live in Darfur and speak a Nilo-Saharan language. The authors observed in their study that "the Masalit possesses by far the highest frequency of the E-M78 and of the E-V32 haplogroup", which they believe suggests "either a recent bottleneck in the population or a proximity to the origin of the haplogroup." However, More recently, Tillmar et al. (2009) typed 147 males from Somalia for 12 Y-STR loci, and observed that 77% (113/147) had typical E-V32 haplotypes. This is the highest frequency of E-V32 found in any single sample population.

The STR data from Cruciani et al. (2007) concerning E-V12 can be summarized as follows.

E-V13

The E-V13 clade is equivalent to the "alpha cluster" of E-M78 reported in Cruciani et al. (2004), and was first defined by the SNP V13 in Cruciani et al. (2006). Another SNP is known for this clade, V36, reported in Cruciani et al. (2007). All known positive tests for V13 are also positive for V36. So E-V13 is currently considered "phylogenetically equivalent" to E-V36.

Haplogroup E-V13 is the only lineage that reaches the highest frequencies out of Africa. In fact, it represents about 85% of the European E-M78 chromosomes with a clinal pattern of frequency distribution from the southern Balkan peninsula (19.6%) to western Europe (2.5%). The same haplogroup is also present at lower frequencies in Anatolia (3.8%), the Near East (2.0%), and the Caucasus (1.8%). In Africa, haplogroup E-V13 is rare, being observed only in northern Africa at a low frequency (0.9%).

—Cruciani et al. (2007)

Within Europe, E-V13 is especially common in the Balkans and some parts of Italy. In different studies, particularly high frequencies have been observed in Kosovar Albanians (45.6%) (Peričic et al. (2005)), Macedonian Albanians (34.4% reported in Battaglia et al. (2008)), and in some parts of Greece (about 35% in some of the areas studied by King et al. (2008).^[14] More generally, high frequencies have also been found in other areas of Greece, and amongst Bulgarians, Romanians, Macedonians and Serbs.^{[4][12][15][16]}

Within Italy, frequencies tend to be higher in Southern Italy,^[1] with particularly high results sometimes seen in particular areas; for example, in Santa Ninfa and Piazza Armerina in Sicily.^[17] High frequencies appear to exist also in some northern areas^{[Note 4]} for example around Venice,^{[Note 5]} Genoa^[18] and Rimini,^[19] as well as on the island of Corsica, which is to the west of mainland northern Italy.^[20]

E-V13 is also found in scattered and small amounts in Libya (in the Jewish community) and Egypt, but this is considered most likely to be a result of migration from Europe or the Near East.^[1]

E-V13 and ancient migrations

The apparent movement of E-M78 lineages from the Near East to Europe, and their subsequent rapid expansion, make its E-V13 sub-clade a particularly interesting subject for speculation about ancient human migrations.

Phylogenetic analysis have suggested to some researchers that these lineages have spread through Europe, from the Balkans in a "rapid demographic expansion".^[1] Before then, the SNP mutation, V13 apparently first arose in West Asia around 10 thousand years ago, and although not widespread there, it is for example found in high levels (>10% of the male population) in Turkish Cypriot and Druze Arab lineages.^[1] The Druze are considered a genetically isolated community, and are therefore of particular interest.^[21] The STR DNA signature of some of the E-V13 men amongst them was actually originally classified in the delta cluster in Cruciani et al. (2004). This means that Druze E-V13 clustered together with most E-V12 and E-V22, and not with European E-V13, which was mostly in the alpha cluster. This can be summarized in a table format...

Early migration from the Middle East to Europe

The distribution and diversity of V13 are often thought to represent the introduction of early farming technologies, during the Neolithic expansion, into Europe by way of the Balkans.^[11] The haplogroup J2b (J-M12) has also frequently been discussed in connection with V13, as a haplogroup with a seemingly very similar distribution and pre-history.^[2][4][11] (There is no consensus regarding the circumstances or timing of its evolution.)

Cruciani et al. (2007) says there were at least four major demographic events which have been envisioned for this geographic area:

• The "post-Last Glacial Maximum expansion (about 20 kya)"
• The "Younger Dryas-Holocene reexpansion (about 12 kya)"
• The "population growth associated with the introduction of agricultural practices (about 8 kya)"
• The "development of Bronze technology (about 5kya)"

The last two seem within the timespan possible for V13 given its STR age of arise putatively in the Middle East. In favor of the agricultural connection, human remains excavated in a Spanish funeral cave dating from approximately 7000 years ago were shown to be in this haplogroup.^[22]

However, earlier entry into Europe is also possible. Battaglia et al. (2008), for example, propose that the E-M78* lineage ancestral to all modern E-V13 men moved rapidly out of a Southern Egyptian homeland, in the wetter conditions of the early Holocene; arrived in the Balkans with only Mesolithic technologies and then only subsequently integrated with Neolithic cultures which arrived later in the Balkans.

E-V13 is in any case often described in population genetics as one of the components of the European genetic composition which shows a relatively recent link of populations from the Middle East, entering Europe and presumably associated with bringing new technologies.^[23][24][25] As such, it is also sometimes remarked that it is a relatively recent genetic movement out of Africa into Eurasia, and has been described as "a signal for a separate late-Pleistocene migration from Africa to Europe over the Sinai ... which is not manifested in mtDNA haplogroup distributions".^[26]

After its initial entry in Europe, there was then a dispersal from the Balkans into the rest of Europe. Also for this movement, a wide range of possibilities exists. Battaglia et al. (2008) suggest that the E-V13 sub-clade of E-M78 originated in situ in Europe, and propose that the first major dispersal of E-V13 from the Balkans may have been in the direction of the Adriatic Sea with the Neolithic Impressed Ware culture often referred to as Impressa or Cardial. The above mentioned find of archaic E-V13 in Spain supports this suggestion.

In contrast, Cruciani et al. (2007) suggest that the movement out of the Balkans may have been more recent than 5300 years ago. The authors suggest that for the most part, modern E-V13 descends from a population which remained in the Balkans until the Balkan Bronze age. They consider that "the dispersion of the E-V13 and J-M12 haplogroups seems to have mainly followed the river waterways connecting the southern Balkans to north-central Europe". Peričic et al. (2005) propose the Vardar-Morava-Danube rivers as a possible route of Neolithic dispersal into central Europe. Bird (2007) proposes a still more recent dispersal out of the Balkans, around the time of the Roman empire.

In contrast, another major discovery relevant to the study of E-V13 origins was the announcement in Lacan et al. (2011) that a 7000 year old skeleton in a Neolithic context in a Spanish funeral cave, was an E-V13 man. (The other specimens tested from the same site were in haplogroup G2a, which has been found in Neolithic contexts throughout Europe.) Using 7 STR markers, this specimen was identified as being similar to modern individuals tested in Albania, Bosnia, Greece, Corsica, and Provence. The authors therefore proposed that, whether or not the modern distribution of E-V13 of today is a result of more recent events, E-V13 was already in Europe within the Neolithic, carried by early farmers from the Eastern Mediterranean to the Western Mediterranean, much earlier than the Bronze age.

Greek soldiers in Pakistan

Both E-M78 and J-M12 have also been used in studies seeking to find evidence of a remaining Greek presence in Afghanistan and Pakistan, going back to the time of Alexander the Great.

An extensive analysis of Y diversity within Greeks and three Pakistani populations – the Burusho, Kalash and Pathan – who claim descent from Greek soldiers allowed us to compare Y lineages within these populations and re-evaluate their suggested Greek origins. This study as a whole seems to exclude a large Greek contribution to any Pakistani population, confirming previous observations. However, it provides strong evidence in support of the Greek origins for a small proportion of Pathans, as demonstrated by the clade E network and the low pairwise genetic distances between these two populations.

—Firasat et al. (2006)

This study however tested only for M78, and not V13, the typical type of M78 from the Balkans. More recent and detailed analyses of E-V13 in this region have however concluded that this hypothesis is incorrect, and that the variants found there are not the types typical of the Balkans.^[27] Instead "Afghanistan's lineages are correlated with Middle Easterners and Iranians but not with populations from the Balkans"^[28]

Roman soldiers in Britain

Significant frequencies of E-V13 have also been observed in towns in Wales, Chester (ancient Deva Victrix) in England, and Scotland. The old trading town of Abergele on the northern coast of Wales in particular showed 7 out of 18 local people tested were in this lineage (approximately 40%), as reported in Weale et al. (2002). Bird (2007) attributes the overall presence of E-V13 in Great Britain, especially in areas of high frequency, to settlement during the 1st through 4th centuries CE by Roman soldiers of Thracian and Dacian ancestry from the Balkan peninsula. Bird proposes a connection to the modern region encompassing Kosovo, southern Serbia, northern Republic of Macedonia, and extreme northwestern Bulgaria (a region corresponding to the Roman province of Moesia Superior), which was identified by Peričic et al. (2005) as harboring the highest frequency worldwide of this sub-clade.^{[Note 6]}

However, according to data published so far,^{[Note 7]} E-V13 appears to be notably absent in Central England, a fact which Bird (2007) suggests reflects a genuine population replacement of Romano-British people with Anglo-Saxons:^{[Note 8]}

The "E3b hole" suggests that either (a) a massive displacement of the native Romano-British population by invasion or, (b) the substantial genetic replacement of Romano-British Y-DNA through an elite dominance ("apartheid") model [ Thomas et al. (2006) ], has occurred in Central England. Regardless of the mechanism, the Central England region of Britain, with its lack of E3b haplotypes, is the area having the most "striking similarity in the distribution of Y-chromosomes" with Friesland.

—Bird (2007)

Sub-clades of E-V13

Although most E-V13 individuals do not show any known downstream SNP mutations, and are therefore categorized as E-V13* there are several recognized sub-clades, all of which may be very small. These are one of two cases where Karafet et al. (2008) remarked that at the time of that article, it was not certain that the two clades were truly separate ("the positions of these mutations have not been resolved because of a lack of a DNA sample containing the derived state at V27").

• E-V27. Defined by V27. Cruciani et al. (2007) found one case in Sicily.
• E-P65. Defined by P65.
• E-L17. Defined by L17.
• E-L143. Defined by L143.
• E-M35.2. Defined by M35.2.
• E-L241. Defined by L241.
• E-L250. Defined by L250, L251, and L252.

E-V22

This clade comprises most of those classified in the "delta cluster" of Cruciani et al. (2004). Cruciani et al. (2006) later noted that "E-V22 and E-V12* chromosomes are intermingled and not clearly differentiated by their microsatellite haplotypes".

This sub-clade of E-M78 is "relatively common"^[1] in the Horn of Africa and Egypt, with higher microsatellite variance (0.35 vs. 0.46, respectively) in Egypt. In the article announcing this first information, Cruciani et al. (2007) described it as uncommon in Western Asia and they proposed Northeast Africa (Libya/Egypt) as this sub-clade's likely place of origin. Hassan et al. (2008) also reported a significant presence in neighboring Sudan, making up about 30% of the diverse range of the country's E-M78 lineages in their study, including 8 out of 26 Fulani (about 31%), a widely-dispersed pastoral people.^{[Note 9]} E-V22 was also present in much smaller frequencies amongst the Shilluk (2 of 15 samples, 13%) and Dinka (3 of 26, 11.5%) Nilotes of Southern Sudan. Hassan et al. suggest that E-V22, like E-V12, might have entered Sudan from North Africa "after the progressive desertification of the Sahara around 6,000–8,000 years ago". They add that the gene flow to Sudan "is not only recent (Holocene onward) but also largely of focal nature", and that "most speakers of Nilo-Saharan languages, the major linguistic family spoken in the country, show very little evidence of gene flow and demonstrate low migration rate, with exception of the Nubians, who appear to have sustained considerable gene flow from Asia and Europe together with the Beja."

Other frequencies reported by Cruciani et al. (2007) include Asturians (4.44% out of 90 people), Sicilians (4.58% out of 153 people), Moroccan Arabs (7.27%, 55 people), Moroccan Jews (8%, 50 people), Istanbul Turkish (5.71% out of 35 people), and Palestinians (6.9% out of 29 people). Cadenas et al. (2007) found a 6.7% presence in the UAE.

Sub-clades of E-V22

There are two recognized sub-clades, which are apparently separate, although Karafet (2008) remarked that at the time of that article, "the positions of these mutations have not been resolved because of a lack of a DNA sample containing the derived state at [...] V19".

• E-M148 Defined by M148. Underhill et al. (2000) found 1 example in the Indian subcontinent. Cruciani et al. (2006) calls M148 "rare and rather uninformative".
• E-V19 Defined by V19. Cruciani et al. (2007) found 2 exemplars in Sardinia.

E-V65

This sub-clade, equivalent to the previously classified "beta cluster", is found in high levels in the Maghreb regions of far northern Africa. Cruciani et al. (2007) report levels of about 20% amongst Libyan Arab lineages, and about 30% amongst Moroccan Arabs. It appears to be less common amongst Berbers, but still present in levels of >10%. The authors suggest a North African origin for this lineage. In Europe, only a few individuals were found in Italy and Greece. The results from the article can be summarized as follows...

E-V65	YCAIIa	YCAIIb	DYS413a	DYS413b	DYS19	DYS391	DYS393	DYS439	DYS460	DYS461	A10

number	38	38	38	38	38	38	38	38	38	38	38

Capelli et al. (2009) studied the beta cluster in Europe. They found small amounts in Southern Italy, but also traces in Cantabria, Portugal and Galicia, with Cantabria having the highest level in Europe in their study, at 3.1% (5 out of 161 people).

E-M521

This sub-clade's discovery was announced in Battaglia et al. (2008) They found 2 out of 92 Greeks to have this mutation.

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.
