It's not just about skin color. Nor does cosmetic surgery alter the genetic code.

As Dr. David Duke has explained: A race is a more or less distinct combination of inherited physiological, morphological and behavioral traits. J.Phillippe Rushton describes it this way:

A race is what zoologists term a variety or subdivision of a species. Each race (or variety) is characterized by a more or less distinct combination of inherited morphological, behavioral, physiological traits. In flowers, insects, and non-human mammals, zoologists consistently and routinely study the process of racial differentiation. 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. This process is most apparent when the individuals live in diverse geographic areas and therefore evolve unique, recognizable adaptations (such as skin color) that are advantageous in their specific environments.

But differentiation also occurs under less extreme circumstances. Zoologists and evolutionists refer to such differentiated populations as races. (Within the formal taxonomic nomenclature of biology, races are termed subspecies). Zoologists have identified two or more races (subspecies) in most mammalian species.

Differences between the major races of mankind include over 50 physiological and social variables. Other than the obvious differences in skin color and hair texture, they include brain size, cranial structure, dentition, intelligence, musculature, hormonal levels, sexual norms, temperament, longevity and a wide range of personality traits. As Rushton says eloquently, "If race were an arbitrary, socially constructed concept, devoid of all biological meaning, such consistent relationships would not exist."
