Haplogroup E-V68
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 (also roughly equivalent to E-M35). 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.

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 nomenclature such as "E3b1a" which are designed to show their place on the family tree of all males. These various names change as new discoveries are made and are discussed below.
