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.
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 spread from there into East Africa, South Asia, Europe, Egypt and adjoining regions. T1* may have expanded with the Pre-Pottery Neolithic B culture (PPNB) which originated in West Asia.
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.
