A group of individuals is said to belong to race when all its members share in certain common physical traits that are transmitted through the mechanism of heredity.

The term race or racial group usually refers to the categorization of humans into populations or groups on the basis of various sets of heritable characteristics. The most widely used human racial categories are based on salient traits (especially skin color, cranial or facial features and hair texture), and self-identification.

Conceptions of race, as well as specific ways of grouping races, vary by culture and over time, and are often controversial for scientific as well as social and political reasons. The controversy ultimately revolves around whether or not the concept of race is biologically warranted the ways in which political correctness might fuel either the affirmation or the denial of race and the degree to which perceived differences in ability and achievement, categorized on the basis of race, are a product of inherited (i.e., genetic) traits or environmental, social and cultural factors.
