During this period, the natural and social scientists of the day not only accepted without question the genetic and cultural superiority of the Caucasian; they also asserted that the Caucasian race held a monopoly on evolutionary progress, arguing that "inferior races" were no more than evolutionary survivors doomed by their genetic legacy to remain outcasts from evolution.
Hereditarians and evolutionists believed that "less fit" human races were perishing from the rigors of civilization's struggle and competition. Indeed, racial inferiority lay at the very foundation of the evolutionary framework and, remaining there, rose to the pinnacle of "truth" with the myth of scientific certainty.
