E1b1b is the most common paternal haplogroup among the Tuareg. Most belong to its E1b1b1b (E-M81) subclade, which is colloquially referred to as the Berber marker due to its prevalence among Mozabite, Middle Atlas, Kabyle and other Berber groups. It reaches frequencies of up to 100 percent in some parts of the Maghreb, and is dominated by its sub-clade E-M183. M81 is thought to have originated in North Africa up to 14,000 years ago, but a single 2200-year-old branch M183-PF2546 dominates Northern and Eastern Berbers. Its parent haplogroup E1b1b is associated with Afro-Asiatic-speaking populations, and is thought to have arisen in the Horn of Africa.
