Is there a scientific basis for the idea of "races" of human beings? Where did the idea of "races" originate? When did the "race" idea first come into being? Who is responsible for the "race" idea? How does it function--what purpose does it serve? How is this idea perpetuated, and by whom? How did the human species come to be so inclined toward self-loathing as to invent so divisive an idea as that of "race?"
