. It is dominated by its longer-known sub-clade E1b1b1a1 (E-M78), formerly known as E3b1a and (until the discovery of V68) E1b1b1a. So far, three individuals who are in E-M68 but not E-M78 have been reported in Sardinia, by , when announcing the discovery of V68.

Origins

E1b1b1a (E-M78), like its parent clade E1b1b1 (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 Egypt

 were members of this clade. However, were able to study more data, including populations from North Africa who were not represented in the study, and found evidence that the E-M78 lineages in the Horn of Africa were relatively recent branches (see E1b1b1a1b (E-V32) below). They concluded that Northeast Africa 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".

E-M215, the parent clade of E-M78, originated in East Africa during the paleolithic and subsequently, E-M215 spread to Northeast Africa. According to , the presence of E-M78 in East Africa, is the result of a back migration of E-M215 chromosomes that had acquired the E-M78 mutation. 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. The authors believe there were "at least 2 episodes between 23.9–17.3 ky and 18.0–5.9 ky ago".


proposed that the earlier E-V68 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.

propose it as possible from "trans-Mediterranean migrations directly from northern Africa to Europe (mainly in the last 13,000 years ago)", and flow from North Africa to western Asia between 20,000 and 6,800 years ago.

 and Southern Italy (of people carrying the subclades 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

Similarly, , writing prior to the discovery of E-V68 as a larger clade containing E-M78, 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

Towards the south, also explain evidence that some subclades of E-M78, 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".

Age

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. use two calculation methods for estimating the age of E-M78 which give very different results.

E1b1b1a1b (E-V13)

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

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.

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.
