Haplogroup E-P2

E-P2 had an ancient presence in the Levant; presently, it is primarily distributed in Africa where it may have originated, and occurs at lower frequencies in the Middle East and Europe.

Using the principle of the phylogeographic parsimony, the resolution of the E-M215 trifurcation in favor of a common ancestor of E-M2 and E-M329 strongly supports the hypothesis that haplogroup E-P2 originated in eastern Africa, as previously suggested, and that chromosomes E-M2, so frequently observed in sub-Saharan Africa, trace their descent to a common ancestor present in eastern Africa.

The paraclade, referred to as E-P2*, and including cases which are neither in E-V38 or E-M215 are either rare or nonexistent, and so far none have been found.

[9] Stefflova et al. (2009) reported one individual out of a sample of 199 African American men from Philadelphia with E-P2 (xM35, xM2).

[1] Prior to 2002, there were in academic literature at least seven naming systems for the Y-Chromosome Phylogenetic tree.

This allows a researcher reviewing older published literature to quickly move between nomenclatures.
