Race differences show up early in life.

The biological factors underlying race differences in sports have consequences for educational achievement, crime and sexual behavior.

Startling, and alarming to many, is the conclusion that follows from these data that if all people were treated the same, most average race differences would not disappear.

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

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

Nonetheless, much has been learned by studying the statistical differences between the various human races.
