In this paper we discuss the role of the Kushites in the spread of R1*-M173. Human y-chromosome haplogroup R1*-M173 is mainly found in Africa. Haplogroup R1*-M173 is the pristine form of haplogroup R. In Africa researchers have detected frequencies as high as 95% among Sub-Saharan Africans. The phylogenetic, craniometric, textual, historical and linguistic evidence support the dem ic diffusion of Niger- Congo (Nilo-Saharan) carriers of R1*-M173 from Africa to Eurasia between 4-5kya.
