Race: scientific nonproblem, cultural quagmire.
The matter of biological differentiation among human beings has been a perennial concern of physical anthropologists, whose profession grew out of the monogenist/polygenist debates of the 18th century, and who periodically feel impelled to issue sonorous pronouncements on the subject. In spite of (or perhaps because of) the extensive and difficult cultural ramifications of the race issue, such pronouncements have usually presented the matter of race as one that requires extensive bioanthropological exegesis. In reality, however, race is the most banal of biological issues. Within any species, including Homo sapiens, two biological processes are possible: physical differentiation (as routinely occurs in small population isolates) and reintegration (should the resulting differentiated populations come together in the absence of any barrier to mating). The history of Homo sapiens reflects both of these processes: initial differentiation among small, scattered populations in the later part of the Pleistocene, and subsequent reintegration as the human population expanded and these populations came together once more. It is for this reason that, while certain modal physical types can be recognized on any urban street today (differentiation), it is impossible to recognize any clear boundaries between them (reintegration). All of this is perfectly unremarkable in evolutionary terms, and requires no special explanation. The complexities of the race issue are real, of course, and it is important that we come to terms with them; but they will not be resolved by biologists.
