What does modern scientific evidence really tell us about human variation, and what do our differences mean? I read the genetic and medical literature, I investigated the history of the scientific ideas, I interviewed some of the leading researchers in their fields. What became clear was that biology can’t answer this question, at least not fully. The key to understanding the meaning of race is understanding power. When you see how power has shaped the idea of race and continues to shape it, how it affects even the scientific facts, everything finally begins to make sense.
