Charles Darwin(1809-1882), known for his theory of natural selection, believed that there were distinct races, and that human evolution was progressive, meaning that the white races were thought to be more evolved than the black races as he stated in his The Decent of Man. Carl Linnaeus(1707-1778), who created the binomial nomenclature to show the relations between species of animals, put humans into the order primates, and thought that there were four human sub-species- European Whites, American Reds (Native Americans), Asian Browns, and African Blacks.
