The highest frequency of this gene occurs in the Lakota Sioux tribes living on reservations like Pine Ridge and Standing Rock in South Dakota. Forensic studies show that sixty percent of them have it. It has therefore been named after their heroic leader, Crazy Horse (died September 5, 1877). Half of all Siberian natives today also have it, as do 43% of Mexican Huichol Indians, often referred to as a Nation of Shamans. Shamanism seems to be a common denominator of many of the populations carrying this marker. For the Sioux, Huichols and kindred tribes in Siberia and Mongolia spiritual action is a way of life, something inherent to life itself, a living in harmony with nature and all of creation.
