Few concepts are as emotionally charged as that of race. The word conjures up a mixture of associations—culture, ethnicity, genetics, subjugation, exclusion and persecution. But is the tragic history of efforts to define groups of people by race really a matter of the misuse of science, the abuse of a valid biological concept? Is race nevertheless a fundamental reality of human nature? Or is the notion of human “races” in fact a folkloric myth? Although biologists and cultural anthropologists long supposed that human races—genetically distinct populations within the same species—have a true existence in nature, many social scientists and geneticists maintain today that -- Ad Right The consensus among Western researchers today is that human races are sociocultural constructs. Still, the concept of human race as an objective biological reality persists in science and in society. It is high time that policy makers, educators and those in the medical-industrial complex rid themselves of the misconception of race as type or as genetic population. This is the message of two recent books: Race?: Debunking a Scientific Myth, by Ian Tattersall and Rob DeSalle, and Race and the Genetic Revolution: Science, Myth, and Culture, edited by Sheldon Krimsky and Kathleen Sloan. Both volumes are important and timely. Both put race in the context of the history of science and society, relating how the ill-defined word has been given different meanings by different people to refer to groups they deem to -- Before we turn to the books themselves, a little background is necessary. A turning point in debates on race was marked in 1972 when, in a paper titled “The Apportionment of Human Diversity,” Harvard geneticist Richard Lewontin showed that human populations, then held to be races, were far more genetically diverse than anyone had imagined. Lewontin’s study was based on molecular-genetic techniques and provided statistical analysis of 17 polymorphic sites, including the major blood groups in the races as they were conventionally defined: Caucasian, African, Mongoloid, South Asian Aborigines, Amerinds, Oceanians and Australian Aborigines. What he found was unambiguous—and the inverse of what one would expect if such races had any biological reality: The great majority of genetic variation (85.4 percent) was within so-called races, not between them. Differences between local populations accounted for 8.5 percent of total variation; differences between regions accounted for 6.3 percent. The genetic divergence between -- human genome, Craig Venter of the Institute of Genetic Research and Francis Collins of the National Institutes of Health declared that the concept of race had no genetic basis. Genetics offered no support for those wishing to place precise racial boundaries around groups. Despite rebuttals and objections, no matter how one cuts it, the data have come out much the same: Between 5 and 7 percent of human genetic diversity is between subgroups within the classically defined races; 6 to 10 percent of the total human variation is between those groups that we think of as races in an everyday sense based on skin color. The remainder of the variation occurs at the individual level and cannot be categorized by group or subgroup. -- Certainly some traits are more clustered in specific populations than in others, such as skin color, hair form, nose shape and blood type. But race is little more than skin deep in biological terms, and individuals are frequently more genetically similar to members of other so-called races than they are to their own said race. Race?: Debunking a Scientific Myth is a beautifully presented book, elegantly reasoned and skillfully written. Tattersall, a physical anthropologist, and DeSalle, a geneticist, are both senior scholars at -- of previously isolated groups—due to migrations, invasions and colonization—is that no clear boundaries can be drawn around the variety of humans, no “races” of us. The data for tracking lineages come from genomics, DNA comparisons and the study of genetic markers. Tattersall and DeSalle argue that not only are the differences between the classically defined “races” very superficial, they are also of surprisingly recent origin; the variety of human populations seems to have both accumulated and begun to -- us has arisen in a blink of evolution’s eye. The process of relative geographic isolation of local populations into what might have been true races (genetically differentiated populations) during the last Ice Age began to reverse as formerly isolated human groups came back into contact and interbred. That reintegration, which has occurred -- great migration and widespread mating of individuals from disparate geographic origins. The result is that individuals identified as belonging to one “race,” based on the small number of visible characters used in historical race definitions, are likely to have diverse ancestry. The distinction between ancestry and race has important implications, as the authors discuss. Although race is void of biological foundation, it has a profound social reality. All too apparent are disparities in health and welfare. Despite all the evidence indicating that “race” has no biological or evolutionary meaning, the biological-race concept continues to gain strength today in science and society, and it is reinforced by those who design and market DNA-based technologies. Race is used more and more in forensics, medicine and the genetic-ancestry business. Tattersall and DeSalle confront those industries head on and in no uncertain terms, arguing that “race-based medicine” and “raced-based genomics” are deeply flawed. Individuals fall ill, not populations. Belonging to any socioculturally defined race is a poor predictor of an individual’s genes, and one’s genes a poor predictor of one’s health. Race and the Genetic Revolution: Science, Myth, and Culture arose from two projects, both funded by the Ford Foundation and organized by the Council for Responsible Genetics, that “examined the persistence of the concept of human races within science and the impacts such a concept has had on disparities among people of different geographical ancestries.” The first project brought together academics and social-justice advocates to discuss “racialized” forensic DNA databases and seek policy solutions. The second focused on the effects of modern genetic technology in reinscribing and naturalizing the concept of race in science and society. The resulting book is a fine and richly textured compilation, in which a multidisciplinary group of scholars explore racialized medicine, various uses of genetic testing in forensics and the genetic-ancestry industry, and attempts to link intelligence and race. Sociologist Troy Duster argues that the growing genetic-ancestry industry not only reinforces a biological conception of race but is sorely in need of government regulation in regard to claims made and accuracy of methods used to pinpoint ancestry, as was suggested by the -- A different aspect of racial profiling is evident in the growing industry of racialized medicine, whose proponents might argue that even if race has no evolutionary or biological meaning, it can still be useful for medical treatments. After all, more and more diseases are reportedly correlated with ethnicity and race. But as evolutionary biologists Joseph L. Graves Jr. and Jonathan Kahn argue in their respective chapters on the subject, racialized medicine is a bad investment and is bound to fail for two reasons. First, although individual ancestries are useful on medical questionnaires, ancestry should not be conflated with race. “The issue is not primarily one of whether to use racial categories in medical practice but how,” Kahn writes. Carefully taking account of race to help understand broader social or environmental factors that may be influencing health disparities can be warranted. . . . But it is always important to understand that race itself is not an inherent causal factor in such conditions. -- and other cultural factors. Science has exposed the myth of race, but as the diverse array of essays in Race and the Genetic Revolution shows, folk conceptions of racial typology are kept alive in various sociopolitical forms, and proponents of various DNA-based technologies continue to use erroneous biological conceptions of race as the rationale for using these technologies. Race is not just a sociocultural construct; it is a technological and commercial artifact that persists today. __________________________________________________________________
