In order for a species to have different subspecies, there needs to be greater genetic diversity between its populations than within its populations. What does this requirement tell us about the existence of biological races in humans? In this scrollable interactive, we explain that humans can’t be divided into biological races because we have more genetic diversity within our populations than between them. To learn more about how genetic diversity can be measured in human populations, please explore The Geographical Spread of Human Genetic Variation.
