Hutu the government of Rwanda seems to no longer use any such distinction. Modern-day genetic studies of the Y-chromosome suggest that the Hutu, like the Tutsi, are largely of Bantu extraction (83% E1b1a, 8% E2). Paternal genetic influences associated with the Horn of Africa and North Africa are few (3% E1b1b and 1% R1b), and are ascribed to much earlier inhabitants who were assimilated. However, the Hutu have considerably fewer Nilo-Saharan paternal lineages (4.3% B) than the Tutsi (14.9% B). In general, the Hutu appear to share a close genetic kinship with neighboring Bantu populations, particularly the Tutsi. However, it is
Origins of Hutu, Tutsi and Twa communities (17.7% Afro-Asiatic genes found in the mixed Hutu/Tutsi population). While most supporters of the migration theory are also supporters of the "Hamitic theory", namely that the Tutsi came from the Horn of Africa, a later theory proposed that the Tutsi had instead migrated from nearby interior East Africa, and that the physical differences were the result of natural selection in a dry arid climate over millennia. Among the most detailed theories was one put forward by Jean Hiernaux, based on studies of blood factors and archeology. Noting the fossil record of a tall people with narrow facial features several
