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

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

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

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.

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

Sometimes it is claimed by those who argue that race is just a social construct that the human genome project shows that because people share roughly 99% of their genes in common, that there are no races. This is silly.

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.
