Our single race is independent of geographic origin, ethnicity, culture, color of skin or shape of eyes — we all share a single phenotype, the same or similar observable anatomical features and behavior.
Science highlights these similarities in our embryonic development, physiology (our organ-based systems), biochemistry (our metabolites and reactions), and more recently, genomics (our genetic makeup). As a molecular biologist, this last one is indeed the most important to me — data show that the DNA of any two human beings is 99.9 percent identical, and we all share the same set of genes, scientifically validating the existence of a single biological human race and one origin for all human beings. In short, we are all brothers and sisters.
Genetically speaking, studies have shown that there is much greater genetic variation within a given human population (e.g., Africans, Caucasians, or Asians) than between populations (Africans vs. Caucasions), indicating that human variation cannot be subdivided into discrete races.

Race and Racial Identity Are Social Constructs

What We Mean When We Say 'Race Is a Social Construct'
Andrew Sullivan and Freddie Deboer have two pieces up worth checking out. I disagree with Andrew's (though I detect some movement in his position.) Freddie's piece is entitled "Precisely How Not to Argue About Race and IQ." He writes:
The problem with people who argue for inherent racial inferiority is not that they lie about the results of IQ tests, but that they are credulous about those tests and others like them when they shouldn't be; that they misunderstand the implications of what those tests would indicate even if they were credible; and that they fail to find the moral, analytic, and political response to questions of race and intelligence.

Turkheimer's findings make perfect sense once you recognize that IQ scores reflect some varying combination of differences in native ability and differences in opportunities. Among rich kids, good opportunities for developing the relevant cognitive skills are plentiful, so IQ differences are driven primarily by genetic factors. For less advantaged kids, though, test scores say more about the environmental deficits they face than they do about native ability.
More generally, IQ tests reward the possession of abstract theoretical knowledge and a facility for formal analytical rigor. But for most people throughout history, intelligence would have taken the form of concrete practical knowledge of the resources and dangers present in the local environment. To grasp how culturally contingent our current conception of intelligence is, just imagine how well you might do on an IQ test devised by Amazonian hunter-gatherers or medieval European peasants.
