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

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

We emigrated to South Africa and later to Canada so I went to school in several places.

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

I then moved to the University of Western Ontario where I was made a full professor in 1985.

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

But with each passing year and each new study, the evidence for the genetic contribution to these [individual and group] differences becomes more firmly established than ever.
