Haplogroup E1b (Y-DNA)

Haplogroup E1b
Possible time of origin 40000 years BP
Possible place of origin Africa[1]
Ancestor E1
Descendants E1b1, E1b2
Defining mutations P177

In human genetics, Haplogroup E1b (P177) is a human Y-chromosome DNA haplogroup.

Haplogroup E1b, along with haplogroup E1a, make up the two main components of the older E1. So far there are no attested exempliars of E1b*. The clade is dominated by subclade E1b1 (E-P2 or E-PN2), which is by far the most frequent. Another subclade of E1b, E1b2 (P75), was announced in Hammer et al. (2003) and confirmed as a sibling to E1b1 in Karafet et al. (2008).

Tree

This phylogenetic tree of haplogroup subclades is based on the YCC 2008 tree [2] and subsequent published research.
