Haplogroup T-M184

Haplogroup T-M184, also known as Haplogroup T, is a human Y-chromosome DNA haplogroup. The unique-event polymorphism that defines this clade is the single-nucleotide polymorphism known as M184.

This article is about the human Y-chromosome haplogroup T-M184. For the unrelated human mtDNA Haplogroup, see Haplogroup T (mtDNA).

T-M184 is unusual in that it is both geographically widespread and relatively rare. T1 (T-L206) – the numerically dominant primary branch of T-M184 – appears to have originated in Western Asia, and possibly spread from there into East Africa, South Asia, Europe and adjoining regions. T1* may have expanded with the Pre-Pottery Neolithic B culture (PPNB).

Subclades of T-M70 appear to have been present in Europe since the Neolithic with Neolithic Farmers from Western Asia. The moderately high frequency (~18%) of T1b* chromosomes in the Lemba of southern Africa supports the hypothesis of a West Asian origin for their paternal line.
