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 colours -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.
