Haplogroup E3b (Y-DNA)
In human genetics, Haplogroup E3b (M35) (previously called Hg21) is a Y-chromosome haplogroup with a distribution spreading from Africa around the Mediterranean into Europe and the Middle East. It is defined by the Single nucleotide polymorphism (SNP) mutations M215 and M35, which are almost always found together.
E3 (defined by SNPs P2, DYS391p) is a branch of the African haplogroup E (defined by SNPs SRY4064 (SRY8299 or M40), M96, P29). The other main branch of E3 is E3a, defined by SNPs M2 (SY81) (DYS271), M180, P1, P46.
E3b is believed to have first appeared in the Horn of Africa approximately 26,000 years ago and dispersed to the Middle East during the Upper Paleolithic and Mesolithic periods. From there, it traveled north and west with the expansion of Neolithic agriculturalists.
Outside of East Africa, its two most prevalent clades are:
Additional recommended knowledge
This haplogroup arose ca. 18.6 kya after the spread of E3b1* (E-M35) from the Horn of Africa to Egypt, and has been further divided into subclades by Fulvio Cruciani, on the basis of the following SNP mutations...
