Most biologists and anthropologists do not recognize race as a biologically valid classification, in part because there is more genetic variation within groups than between them.
2. A group of people united or classified together on the basis of common history, nationality, or geographic distribution: the Celtic race.
3. A genealogical line; a lineage.
