“Two decades ago, analysis of the human genome established that all human beings are 99.9 percent the same. “Race is a social concept, not a scientific one,” said J. Craig Venter, the geneticist who ran Celera Genomics when the mapping was completed in 2000. “We all evolved in the last 100,000 years from the small number of tribes that migrated out of Africa and colonized the world.” Which means that an entire racial caste system, the catalyst of hatreds and civil war, was built on what the anthropologist Ashley Montagu called “an arbitrary and superficial selection of traits,” derived from a few of the thousands of genes that make up a human being. “The idea of race,” Montagu wrote, “was, in fact, the deliberate creation of an exploiting class seeking to maintain and defend its privileges against what was profitably regarded as an inferior caste.”
