A race is what zoologists term a variety or subdivision of a species.

Each race (or variety) is characterized by a more or less distinct combination of inherited morphological, behavioral, physiological traits.

Deconstructing the concept of race not only conflicts with people's tendency to classify and build family histories according to common descent but also ignores the work of biologists studying non-human species.

To deny the predictive validity of race at this level is nonscientific and unrealistic.

Race differences show up early in life.

Those objecting to the concept of race argue that the taxonomic definitions are arbitrary and subjective.
