Africa: the Great Lakes Twa, Bahrwa, Baka, Aka and Bambuti of central Africa (commonly referred to as Pygmees), the Hadzabe, Hai//om, !Kung and Gǀwi of South Africa (commonly referred to as Bushmen)
It was the ancestral haplogroup of not only modern Pygmies like the Baka and Mbuti, but also Hadzabe from Tanzania, who often have been considered, in large part because of some typological features of their language, to be a remnant of Khoisan people in East Africa.
