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

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

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

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.

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

Race differences show up early in life.

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.
