Does Race Exist?
The concept of race is one of the most intellectually and emotionally charged subjects, not only in society but in science as well. NOVA Online asked two leading anthropologists, Dr. Loring Brace of the University of Michigan and Dr. George Gill of the University of Wyoming, who fall on either side of the debate about whether race exists in biologic terms, to state their points of view. Regardless of where you stand on the issue, we think you will find their arguments well-reasoned and thought-provoking.
Slightly over half of all biological/physical anthropologists today believe in the traditional view that human races are biologically valid and real. Furthermore, they tend to see nothing wrong in defining and naming the different populations of Homo sapiens. The other half of the biological anthropology community believes either that the traditional racial categories for humankind are arbitrary and meaningless, or that at a minimum there are better ways to look at human variation than through the "racial lens."
Pro and con
Are there differences in the research concentrations of these two groups of experts? Yes, most decidedly there are. As pointed out in a recent 2000 edition of a popular physical anthropology textbook, forensic anthropologists (those who do skeletal identification for law-enforcement agencies) are overwhelmingly in support of the idea of the basic biological reality of human races, and yet those who work with blood-group data, for instance, tend to reject the biological reality of racial categories.
Bones don't lie
First, I have found that forensic anthropologists attain a high degree of accuracy in determining geographic racial affinities (white, black, American Indian, etc.) by utilizing both new and traditional methods of bone analysis. Many well-conducted studies were reported in the late 1980s and 1990s that test methods objectively for percentage of correct placement. Numerous individual methods involving midfacial measurements, femur traits, and so on are over 80 percent accurate alone, and in combination produce very high levels of accuracy. No forensic anthropologist would make a racial assessment based upon just one of these methods, but in combination they can make very reliable assessments, just as in determining sex or age. In other words, multiple criteria are the key to success in all of these determinations.
