Haplogroup T-PF7455 is the only localized African branch of T-M70. Entering the Green Sahara of North Africa from the Levant, this clade spread Afro-Asiatic languages within Africa, along with pastoralism and cultivation of new animals and farming methods that previously did not exist in Africa before these Levantine farmers turned Saharan Pastoralists entered. Early samples of T show this was a paternally led movement which mixed PPNB (before any Irano-Caucaso ancestry) + Local North African (Berber-like) ancestry. This paternal group would eventually go on to father 31% of Toubou, a Chadic people, 18% of Fulanis (Woodabe and Adamawa tribe), 10% of Egyptians, Sudanese/Nubians, and Maghrebis.
T-FT7904 became the westward moving branch in the Sahel. T-Y13384 (T-Y12641) localized in the Eastern Sahara of Egypt and Sudan seen in Kulubnarti Nubians. T-Y22559 followed a Barbary coast medditeranean route, with earliest clades T-FT222060 seen in Egypt & Libya (this is the clade with an Ancient Egyptian). Other branches of T-Y22559 sporadically settled in the Barbary coast. The youngest main branch is T-CTS6087, moving north from Maghreb - Gibraltar into Spain and settling with different Mediterranean Europeans, reaching the British Isles. All descendants of T-PF7455 were originally North African.
