In 2000, the Human Genome Project finally answered one of the most fundamental questions about race: What, if anything, is the genetic difference between people of different skin colors -- black, white, Hispanic, Asian? The answer: nearly nothing. As it turns out, we all share 99.99 percent of the same genetic code -- no matter our race -- a fact that, geneticist J. Craig Venter claimed, proves that race is a "social concept, not a scientific one."
