The mean pattern of educational and economic achievement within multi-racial countries such as Canada and the United States has increasingly been found to prove valid internationally.

Of course, individuals vary greatly within each racial group and should be treated as such.

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.

Formation of a new race takes place when, over several generations, individuals in one group reproduce more frequently among themselves than they do with individuals in other groups.

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

I received a D.Sc. from the University of London in 1992.
