[6] According to geneticist Spencer Wells, haplogroup K or the Eurasian clan, originated in the Middle East (perhaps Iran) or Central Asia.

[1][2][3] Basal K* is exceptionally rare and under-researched; while it has been reported at very low frequencies on many continents it is not always clear if the examples concerned have been screened for subclades.

T is most common among: Fulanis, Toubou, Tuareg, Somaliland, Egyptians, some Middle East,[33] the Aegean Islands and among Kurru, Bauris and Lodha in India.

K2* (M526) has been found in an estimated 27% of indigenous Australians (based on large scale surveys in which 56% of the samples were assumed to be non-indigenous.).

[34] According to Mark Lipson et al.(2014), from MIT – Massachusetts Institute of Technology, United States Of America, from his jurnal: "New  statistical  genetic methods for elucidating the history and evolution of human populations”, K2* (M526) has also been found in Toba-Batak and Mandar in an estimated 14%.

Ancient samples include 10 out of 11 samples from Xiaohe Tomb complex, Andronovo, Pazyryk, Mongolian Altai Kurgans (R1a/Z93 mixed with Q1a2a1/L54), The Tagar Culture, Karasuk culture, Tashtyk culture, some Corded ware folk R1b West Europe, Chadic Languages, Banjara tribes of India, Hazaras of Pakistan, Armenian Highlands (Found in several Bell Beakers from Germany and in late antique Basques of whom it is still common in as well as 13.3% (4):one P probably R1b2 (V88): of Guanches from the Canary Islands, (reports of King Tut belonging to R1b, by iGENEA belonging to R1b have not been verified.)
