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