Does Race Exist?

  • Posted 02.15.00
  • NOVA

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.

AN ANTAGONIST'S PERSPECTIVE

by C. Loring Brace

I am going to start this essay with what may seem to many as an outrageous assertion: There is no such thing as a biological entity that warrants the term "race."

The immediate reaction of most literate people is that this is obviously nonsense. The physician will retort, "What do you mean 'there is no such thing as race'? I see it in my practice everyday!" Jane Doe and John Roe will be equally incredulous. Note carefully, however, that my opening declaration did not claim that "there is no such thing as race." What I said is that there is no "biological entity that warrants the term 'race'." "You're splitting hairs," the reader may retort. "Stop playing verbal games and tell us what you really mean!"

A bit of context

And so I shall, but there is another charge that has been thrown my way, which I need to dispel before explaining the basis for my statement. Given the tenor of our times at the dawn of the new millennium, some have suggested that my position is based mainly on the perception of the social inequities that have accompanied the classification of people into "races." My stance, then, has been interpreted as a manifestation of what is being called "political correctness." My answer is that it is really the defenders of the concept of "race" who are unwittingly shaped by the political reality of American history. [Read a proponent's perspective, that of anthropologist George Gill.]

But all of this needs explaining. First, it is perfectly true that the long-term residents of the various parts of the world have patterns of features that we can easily identify as characteristic of the areas from which they come. It should be added that they have to have resided in those places for a couple of hundred thousand years before their regional patterns became established. Well, you may ask, why can't we call those regional patterns "races"? In fact, we can and do, but it does not make them coherent biological entities. "Races" defined in such a way are products of our perceptions. "Seeing is believing" will be the retort, and, after all, aren't we seeing reality in those regional differences?

"There is nothing wrong with using geographic labels to designate people."

I should point out that this is the same argument that was made against Copernicus and Galileo almost half a millennium ago. To this day, few have actually made the observations and done the calculations that led those Renaissance scholars to challenge the universal perception that the sun sets in the evening to rise again at the dawn. It was just a matter of common sense to believe that the sun revolves around the Earth, just as it was common sense to "know" that the Earth was flat. Our beliefs concerning "race" are based on the same sort of common sense, and they are just as basically wrong.

Despite the obvious physical differences apparent in these photos, if you traveled south on foot from Scandinavia to Egypt and on to Kenya, you would find a subtle range of gradations in looks such that racial differences are hard to see, Brace says.

No visible boundary

I would suggest that there are very few who, of their own experience, have actually perceived at first hand the nature of human variation. What we know of the characteristics of the various regions of the world we have largely gained vicariously and in misleadingly spotty fashion. Pictures and the television camera tell us that the people of Oslo in Norway, Cairo in Egypt, and Nairobi in Kenya look very different. And when we actually meet natives of those separate places, which can indeed happen, we can see representations of those differences at first hand.

But if one were to walk up beside the Nile from Cairo, across the Tropic of Cancer to Khartoum in the Sudan and on to Nairobi, there would be no visible boundary between one people and another. The same thing would be true if one were to walk north from Cairo, through the Caucasus, and on up into Russia, eventually swinging west across the northern end of the Baltic Sea to Scandinavia. The people at any adjacent stops along the way look like one another more than they look like anyone else since, after all, they are related to one another. As a rule, the boy marries the girl next door throughout the whole world, but next door goes on without stop from one region to another.

We realize that in the extremes of our transit—Moscow to Nairobi, perhaps—there is a major but gradual change in skin color from what we euphemistically call white to black, and that this is related to the latitudinal difference in the intensity of the ultraviolet component of sunlight. What we do not see, however, is the myriad other traits that are distributed in a fashion quite unrelated to the intensity of ultraviolet radiation. Where skin color is concerned, all the northern populations of the Old World are lighter than the long-term inhabitants near the equator. Although Europeans and Chinese are obviously different, in skin color they are closer to each other than either is to equatorial Africans. But if we test the distribution of the widely known ABO blood-group system, then Europeans and Africans are closer to each other than either is to Chinese.

While in skin color Europeans and Chinese are closer to each other than either is to Africans, the distribution of blood groups indicates that Europeans and Africans are closer to each other than either is to Chinese. Enlarge Photo credit: © Huchen Lu/iStockphoto

A matter of geography

Then if we take that scourge sickle-cell anemia, so often thought of as an African disease, we discover that, while it does reach high frequencies in some parts of sub-Saharan Africa, it did not originate there. Its distribution includes southern Italy, the eastern Mediterranean, parts of the Middle East, and over into India. In fact, it represents a kind of adaptation that aids survival in the face of a particular kind of malaria, and wherever that malaria is a prominent threat, sickle-cell anemia tends to occur in higher frequencies. It would appear that the gene that controls that trait was introduced to sub-Saharan Africa by traders from those parts of the Middle East where it had arisen in conjunction with the conditions created by the early development of agriculture.

Every time we plot the distribution of a trait possessing a survival value that is greater under some circumstances than under others, it will have a different pattern of geographical variation, and no two such patterns will coincide. Nose form, tooth size, relative arm and leg length, and a whole series of other traits are distributed each in accordance with its particular controlling selective force. The gradient of the distribution of each is called a "cline" and those clines are completely independent of one another. This is what lies behind the aphorism, "There are no races, there are only clines."

Yes, we can recognize people from a given area. What we are seeing, however, is a pattern of features derived from common ancestry in the area in question, and these are largely without different survival value. To the extent that the people in a given region look more like one another than they look like people from other regions, this can be regarded as "family resemblance writ large." And as we have seen, each region grades without break into the one next door.

"The word 'race' has no coherent biological meaning."

There is nothing wrong with using geographic labels to designate people. Major continental terms are just fine, and sub-regional refinements such as Western European, Eastern African, Southeast Asian, and so forth carry no unintentional baggage. In contrast, terms such as "Negroid," "Caucasoid," and "Mongoloid" create more problems than they solve. Those very terms reflect a mix of narrow regional, specific ethnic, and descriptive physical components with an assumption that such separate dimensions have some kind of common tie. Biologically, such terms are worse than useless. Their continued use, then, is in social situations where people think they have some meaning.

America has a leading role in generating and perpetuating the concept of "race," Brace argues. Enlarge Photo credit: © digitalskillet/iStockphoto

America's role in race

The role played by America is particularly important in generating and perpetuating the concept of "race." The human inhabitants of the Western Hemisphere largely derive from three very separate regions of the world—Northeast Asia, Northwest Europe, and Western Africa—and none of them has been in the New World long enough to have been shaped by their experiences in the manner of those long-term residents in the various separate regions of the Old World.

It was the American experience of those three separate population components facing one another on a daily basis under conditions of manifest and enforced inequality that created the concept in the first place and endowed it with the assumption that those perceived "races" had very different sets of capabilities. Those thoughts are very influential and have become enshrined in laws and regulations. This is why I can conclude that, while the word "race" has no coherent biological meaning, its continued grip on the public mind is in fact a manifestation of the power of the historical continuity of the American social structure, which is assumed by all to be essentially "correct."

Finally, because of America's enormous influence on the international scene, ideas generated by the idiosyncrasies of American history have gained currency in ways that transcend American intent or control. One of those ideas is the concept of "race," which we have exported to the rest of the world without any realization that this is what we were doing. The adoption of the biologically indefensible American concept of "race" by an admiring world has to be the ultimate manifestation of political correctness.

A PROPONENT'S PERSPECTIVE

by George W. Gill

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."

"I am more accurate at assessing race from skeletal remains than from looking at living people standing before me," Gill says. Enlarge Photo credit: © Christopher Futcher/iStockphoto

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.

I happen to be one of those very few forensic physical anthropologists who actually does research on the particular traits used today in forensic racial identification (i.e., "assessing ancestry," as it is generally termed today). Partly this is because for more than a decade now U.S. national and regional forensic anthropology organizations have deemed it necessary to quantitatively test both traditional and new methods for accuracy in legal cases. I volunteered for this task of testing methods and developing new methods in the late 1980s. What have I found? Where do I now stand in the "great race debate?" Can I see truth on one side or the other—or on both sides—in this argument?

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.

"Clines" represent gradients of change, such as that between areas where most people have blue eyes and areas in which brown eyes predominate. Enlarge Photo credit: © Nicholas Monu/iStockphoto

I have a respected colleague, the skeletal biologist C. Loring Brace, who is as skilled as any of the leading forensic anthropologists at assessing ancestry from bones, yet he does not subscribe to the concept of race. [Read Brace's position on the concept of race.] Neither does Norman Sauer, a board-certified forensic anthropologist. My students ask, "How can this be? They can identify skeletons as to racial origins but do not believe in race!" My answer is that we can often function within systems that we do not believe in.

"The idea that race is 'only skin deep' is simply not true."

As a middle-aged male, for example, I am not so sure that I believe any longer in the chronological "age" categories that many of my colleagues in skeletal biology use. Certainly parts of the skeletons of some 45-year-old people look older than corresponding portions of the skeletons of some 55-year-olds. If, however, law enforcement calls upon me to provide "age" on a skeleton, I can provide an answer that will be proven sufficiently accurate should the decedent eventually be identified. I may not believe in society's "age" categories, but I can be very effective at "aging" skeletons.

Deeper than the skin

The next question, of course, is how "real" is age biologically? My answer is that if one can use biological criteria to assess age with reasonable accuracy, then age has some basis in biological reality even if the particular "social construct" that defines its limits might be imperfect. I find this true not only for age and stature estimations but for sex and race identification.

The "reality of race" therefore depends more on the definition of reality than on the definition of race. If we choose to accept the system of racial taxonomy that physical anthropologists have traditionally established—major races: black, white, etc.—then one can classify human skeletons within it just as well as one can living humans. The bony traits of the nose, mouth, femur, and cranium are just as revealing to a good osteologist as skin color, hair form, nose form, and lips to the perceptive observer of living humanity. I have been able to prove to myself over the years, in actual legal cases, that I am more accurate at assessing race from skeletal remains than from looking at living people standing before me. So those of us in forensic anthropology know that the skeleton reflects race, whether "real" or not, just as well if not better than superficial soft tissue does. The idea that race is "only skin deep" is simply not true, as any experienced forensic anthropologist will affirm.

Does discussing the concept of race promote racism? Enlarge Photo credit: © tirc83/iStockphoto

Seeing both sides

Where I stand today in the "great race debate" after a decade and a half of pertinent skeletal research is clearly more on the side of the reality of race than on the "race denial" side. Yet I do see why many other physical anthropologists are able to ignore or deny the race concept. Blood-factor analysis, for instance, shows many traits that cut across racial boundaries in a purely clinal fashion with very few if any "breaks" along racial boundaries. (A cline is a gradient of change, such as from people with a high frequency of blue eyes, as in Scandinavia, to people with a high frequency of brown eyes, as in Africa.)

Morphological characteristics, however, like skin color, hair form, bone traits, eyes, and lips tend to follow geographic boundaries coinciding often with climatic zones. This is not surprising since the selective forces of climate are probably the primary forces of nature that have shaped human races with regard not only to skin color and hair form but also the underlying bony structures of the nose, cheekbones, etc. (For example, more prominent noses humidify air better.) As far as we know, blood-factor frequencies are not shaped by these same climatic factors.

So, serologists who work largely with blood factors will tend to see human variation as clinal and races as not a valid construct, while skeletal biologists, particularly forensic anthropologists, will see races as biologically real. The common person on the street who sees only a person's skin color, hair form, and face shape will also tend to see races as biologically real. They are not incorrect. Their perspective is just different from that of the serologist.

So, yes, I see truth on both sides of the race argument.

On political correctness

Those who believe that the concept of race is valid do not discredit the notion of clines, however. Yet those with the clinal perspective who believe that races are not real do try to discredit the evidence of skeletal biology. Why this bias from the "race denial" faction? This bias seems to stem largely from socio-political motivation and not science at all. For the time being at least, the people in "race denial" are in "reality denial" as well. Their motivation (a positive one) is that they have come to believe that the race concept is socially dangerous. In other words, they have convinced themselves that race promotes racism. Therefore, they have pushed the politically correct agenda that human races are not biologically real, no matter what the evidence.

"How can we combat racism if no one is willing to talk about race?"

Consequently, at the beginning of the 21st century, even as a majority of biological anthropologists favor the reality of the race perspective, not one introductory textbook of physical anthropology even presents that perspective as a possibility. In a case as flagrant as this, we are not dealing with science but rather with blatant, politically motivated censorship. But, you may ask, are the politically correct actually correct? Is there a relationship between thinking about race and racism?

Race and racism

Does discussing human variation in a framework of racial biology promote or reduce racism? This is an important question, but one that does not have a simple answer. Most social scientists over the past decade have convinced themselves that it runs the risk of promoting racism in certain quarters. Anthropologists of the 1950s, 1960s, and early 1970s, on the other hand, believed that they were combating racism by openly discussing race and by teaching courses on human races and racism. Which approach has worked best? What do the intellectuals among racial minorities believe? How do students react and respond?

Three years ago, I served on a NOVA-sponsored panel in New York, in which panelists debated the topic "Is There Such a Thing as Race?" Six of us sat on the panel, three proponents of the race concept and three antagonists. All had authored books or papers on race. Loring Brace and I were the two anthropologists "facing off" in the debate. The ethnic composition of the panel was three white and three black scholars. As our conversations developed, I was struck by how similar many of my concerns regarding racism were to those of my two black teammates.

Although recognizing that embracing the race concept can have risks attached, we were (and are) more fearful of the form of racism likely to emerge if race is denied and dialogue about it lessened. We fear that the social taboo about the subject of race has served to suppress open discussion about a very important subject in need of dispassionate debate. One of my teammates, an affirmative-action lawyer, is afraid that a denial that races exist also serves to encourage a denial that racism exists. He asks, "How can we combat racism if no one is willing to talk about race?"

Who will benefit?

In my experience, minority students almost invariably have been the strongest supporters of a "racial perspective" on human variation in the classroom. The first-ever black student in my human variation class several years ago came to me at the end of the course and said, "Dr. Gill, I really want to thank you for changing my life with this course." He went on to explain that, "My whole life I have wondered about why I am black, and if that is good or bad. Now I know the reasons why I am the way I am and that these traits are useful and good."

A human-variation course with another perspective would probably have accomplished the same for this student if he had ever noticed it. The truth is, innocuous contemporary human-variation classes with their politically correct titles and course descriptions do not attract the attention of minorities or those other students who could most benefit. Furthermore, the politically correct "race denial" perspective in society as a whole suppresses dialogue, allowing ignorance to replace knowledge and suspicion to replace familiarity. This encourages ethnocentrism and racism more than it discourages it.
