Abstract
Scientists have almost universally concluded that the human races are largely equal in regard to innate intelligence and most other traits. In spite of the wide social disparities between the races in the West, no more than approximately one standard deviation difference in mean intelligence exists between the whites and blacks. This fact is contrary to a basic requirement of naturalistic evolution: in order for selection to take place, differences must exist between individual organisms for selection to select from. For selection to work, something first must cause races to develop, a process which in Darwinian terms is called speciation. As evolution progresses, the contrast between groups must become greater, producing development of new definable divisions. The lack of major differences between races, especially in intelligence, the factor most crucial for the major contrast between Homo sapiens and 'lower' forms of life, creates a major difficulty for current evolution theory. In addition, misuse of the theory of evolution was an important factor in the extreme forms of racism, especially that against blacks and Jews, that flourished at the turn of the century and for many years beyond.
