Yakub was a black scientist who lived 6,600 years ago and began the creation of the white race/whites. He is said to have done this through a form of selective breeding which is referred to as "grafting", while he was living on the island of Patmos. The Nation of Islam's theology states that Yakub is the biblical Jacob.
