DNA Ancestry Tests: Simultaneously Powerful and Limited

Using a common DNA ancestry test, President Obama would be 100% Caucasian.

Sometimes genetic tests aren’t as useful as you think they will be. For example, if President Obama were to take a common ancestry DNA test, it would almost certainly come back as 100% Caucasian. Useful, huh?

This sort of test, a mitochondrial DNA (mtDNA) test, can look into the deep past but it can only see mom’s side of the family. And it isn’t even really that powerful. It not only ignores dad’s side of the family, but in reality it can only see a sliver of mom’s as well…

…The other kind of test, the Y chromosome test, can go as far back along the paternal line as the mtDNA test can along the maternal line but it suffers from the same problems. In fact, a surprising number (35%?) of African-American men actually have Caucasian Y chromosomes (well, given plantation life, maybe not so surprising). None of these men will learn anything about their African heritage with this test.

So the bottom line is don’t put too much faith into DNA testing alone. It is kind of fun to trace back your history this way but you are really only following one strand of your ancestral web back in time. The rest of the web is invisible to DNA testing…

…II. THE MYTH OF BLOOD AND OF THE INFERIORITY OF CROSS-BREEDS

Human miscegenation has been and is the subject of infinite debate. Opinions on the subject are conditioned by the views of the disputants on race and racial differences, the opponents of miscegenation starting from the assumption of racial inequality, whereas its defenders take the view that the differences between human groups are not such as to constitute an objection to cross-breeding between them. Hence the first thing needed in the study of the problems raised by human inter-breeding is a clear definition of what is meant by race and the selection of criteria for deciding whether or not any pure races exist.

Even under the loosest definition, race implies the existence of groups presenting certain similarities in somatic characteristics which are perpetuated according to the laws of biological inheritance, allowing for a margin of individual variation.

The peoples of Europe are of such mongrel origin that any attempt at classification according to only two characteristics (colour of eyes and hair) would exclude two-thirds of the population in any region studied; the addition of a third characteristic (cranial formation) would leave us with a still smaller fraction of the population presenting the required combination of all three characteristics; and with the inclusion of stature and nasal index, the proportion of «pure» types would become infinitesimal.

We may take it then that there are no pure human races; at the very most it would be possible to define a pure race in terms of the incidence of one selected somatic characteristic, but never in terms of all or even of the majority of hereditary traits. Nevertheless there is a widespread belief that there was a time in antiquity when racial types were pure, that miscegenation is of relatively recent date, and that it threatens humanity with a general degeneration and retrogression. This belief lacks the slightest support from science. The mixing of races has been going on since the very beginning of human life on earth, though obviously the improvement of communications and the general increase in population has stimulated it in the last two centuries. Migration is as old as the human race, and automatically implies cross-breeding between groups. It is quite possible that the Cro-Magnon type of the upper Paleolithic interbred with Neanderthal man, as seems to be indicated by the discovery of remains displaying intermediate characteristics. Moreover the existence of Negroid and Mongoloid races in prehistoric Europe is a further proof that cross-breeding is not a recent phenomenon, and that the oldest populations of Europe are no more than the product of such miscegenation over thousands of years. Yet they show neither the disharmony nor the degeneration which many writers believe to result from racial interbreeding.

History shows us that all the areas in which a high culture has developed have been the scene of the conquest of an indigenous race by foreign nomadic groups, followed by the breaking down of caste divisions and the creation of new amalgams; these, though regarded as racially homogeneous nations, were in fact no more than new  nationalities comprising different races.

Those who, like Jon A. Mjöen, consider miscegenation dangerous for the future of mankind, assert that it is a source of physical degeneracy and that immunity against certain diseases diminishes. They allege that prostitutes and vagrants are commoner among half-bred than among purebred races, while an increased incidence of tuberculosis and other diseases is observable among the former group, with a diminution of mental balance of vigour and, an increase in criminal tendencies (Harmonic and Disharmonic Race Crossing and Harmonic and Unharmonic Crossings, 1922). These data are not valid because the writer does not specify the types of individuals studied nor the general characteristics of the races which have interbred; he ought also to prove that the specific families whose interbreeding produced the half-breeds examined were physically and mentally healthy and free of any sign of degeneracy or disability. Mjöen also entirely overlooks the influence of the social background on the subjects’ behaviour.

C. B. Davenport also demonstrates (in The Effects of Racial Miscegenation, 1917) the existence of disharmonic phenomena in half-breeds-relatively small digestive organs in a bulky body, well developed teeth in weak jaws, large thighs out of proportion to the body, etc. It is not disputed that there are individuals displaying such characteristics, but it has not been shown that the phenomena are due to miscegenation; similar cases are found among old families while generally speaking crossbreeding between black and white produces well proportioned individuals…

…The notion of humanity as being divided into completely separate racial compartments is inaccurate. It is based on false premises, and more particularly on the «blood» theory of heredity which is as false as the old racist theory. «Of one blood» is a phrase without meaning, since the genes or factors of heredity have no connection whatever with the blood, and are independent elements which not only do not amalgamate but tend to become most sharply differentiated. Heredity is not a fluid transmitted through the blood, nor is it true that the different «bloods» of the progenitors are mixed and combined in their offspring.

The myth of «blood» as the decisive criterion regarding the value of a cross persists even in our own day and men still speak of «blood» as the vehicle of inherited qualities, «of my own blood», «the voice of blood», «mixed blood», «new blood», «half blood», etc. The terms, «blue blood» and «plebeian blood» have become a permanent part of everyday speech as descriptions of the descendants of aristocratic and plebeian families respectively, the last being used in a depreciative sense. «Blood» is also to mean nationality: «German blood», «Spanish blood», «Jewish blood», etc. The criterion reaches the nadir of absurdity in such cases as the classification in the United States of those individuals as «Negroes» or «Indians» who have one-sixteenth part of Indian blood» or «black blood»—that is, when one of their sixteen direct ancestors (great-great-grandparents) was a Negro or an Indian…

…Accordingly we can sum up the position more or less as follows: (a) miscegenation has existed since the dawn of human life; (b) miscegenation results in a greater somatic and psychic variability and allows of the emergence of a great variety of new gene combinations, thus increasing the range of hereditary characteristics in the new population group; (c) speaking biologically, miscegenation is neither good nor bad, its effects being dependent in every case on the individual characteristics of the persons between whom such crossbreeding takes place. As, in general, miscegenation occurs more frequently between individuals on the lower social levels and in unsatisfactory economic and social circumstances, the causes of certain anomalies observable must be sought in this fact rather than in the fact of miscegenation as such; (d) examples of «pure races» or of isolated human groups having developed a high culture independently are the exception; (e) on the contrary the great majority of areas of high civilization are inhabited by obviously cross-bred groups….

TEDxNorthwesternU – Rick Kittles – The Biology of Race in the Absence of Biological Races

TEDxTalks
2011-01-25

Rick Kittles, Professor of Medicine
University of Illinois, Chicago
College of Medicine

Defining “race” continues to be a nemesis. Knowledge from human genetic research is increasingly challenging the notion that race and biology are inextricably linked, engendering tremendous ramifications for human relations, identity and public health. It has become fashionable for geneticists and anthropologists to declare that race is a social construction. However, there is little practical value to this belief since few in the public believe and act on it. Thus race is mainly a social concept which in the US has been based on skin color and ancestry. Yet biomedical studies continue to examine black/ white differences. Kittles discusses why using race in biomedical studies is problematic using examples from U.S. groups which transcend “racial” boundaries and bear the burden of health disparities.

Rick Kittles, PhD, received a BS in biology from the Rochester Institute of Technology in 1989 and a PhD in biological sciences from George Washington University in 1998. He then helped establish the National Human Genome Center at Howard University. Currently, Kittles is an associate professor of medicine in the Division of Epidemiology and Biostatistics at the University of Illinois at Chicago (UIC), as well as the associate director of the UIC Cancer Center.

Kittles is well known for his research of prostate cancer and health disparities among African Americans. He has also been at the forefront of the development of ancestry-informative genetic markers, and how genetic ancestry can be used to map genes for common traits and disease. His work on tracing the genetic ancestry of African Americans has brought light to many issues, new and old, which relate to race, ancestry, identity, and group membership.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.

The Growing Need for a National Eugenic Program

The Growing Need for a National Eugenic Program

Bios
Volume 7, Number 3 (October, 1936)
pages 176-187

Sue D. Comer

This paper received second award in the 1936 undergraduate competition.

There has been much discussion during the past half century concerning Eugenics. This discussion has not been limited to scientists but has interested laymen as well who have looked upon the subject as something mysterious and new. As a matter of fact, however, Eugenics is not new. The old saying “There’s nothing new under the sun” holds true again. In very early times a sort of Eugenics program was carried out by nature herself; there was natural selection or to put it in another way the survival of the fittest. In ancient Sparta there was a rather ruthless program in which all the defective children were abandoned because there was no place for them in society. Thus on up through the years men have given the subject of human betterment consideration. “As early as the first half of the sixth century B.C. the Greek poet, Theognis of Megara, wrote: ‘We look for rams and asses and stallions of good stock, and one believes that good will come of good: yet a good man minds not to wed an evil daughter of an evil sire, if he but give her much wealth. . . . Wealth confounds our stock. Marvel not that the stock of our fold is tarnished, for the good is mingled with the base.’ ” A century later Plato set forth a eugenic plan in which the best were to mate the best and the worst, the worst. The best were to be encouraged in having large families; the worst, small families or none at all, and the children of the unfit were to be done away with. At about this same time, Aristotle had a program for eugenics which was based on the belief that the state should have the right of intervention in the interest of reproductive selection.

“For nearly two thousand years after this, conscious eugenic ideals were largely ignored. Constant war reversed natural selection, as it is doing today, by killing off the physically fit and leaving the relatively unfit to reproduce the race, while monasticism and the enforced celibacy of the priesthood performed a similar office for many of the mentally superior, attracting them to a career in which they could leave no posterity. At the beginning of the last century a germ of modern eugenics is visible in Malthus famous essay on population, in which he directed attention to the importance of the birthrate for human welfare, since this essay led Darwin and Wallace to enunciate the theory of natural selection, and to point out clearly the effects of artificial selection. It is really on Darwin’s work that the modern science of eugenics is based, and it owes its beginning to Darwin’s cousin, Francis Galton.”…

…We have considered the inbreeding of the human race; now let us turn to the question of outbreeding.

The outbreeding of the human race may result happily or unhappily depending upon elements entering in the cross from either side. There is undoubtedly a difference of temperament among the races and, though this difference may seem small, it is to this that a nation may owe its success or failure. Between races of such great diversity as European and Japanese there is hardly likely to result a happy blend. “The genes now carried by each group are the foundations of at least moderately successful and distinct racial types, and it is hardly likely that a mixture of genes would produce an equally coherent and satisfactory type.” There are records of extremely successful crosses of such nature but these should not lead us to expect such lucky accidents each time. If, however, the races to be blended are of the same fundamental type, there should be no hesitancy concerning the success of the marriage on the racial score.

Professor Thorndike has made measurements in comparing the white and colored races and finds the difference to be from five to ten per cent lower intellect in the Negroes. It is evident from this information that interbreeding with the colored race will tend to lower the intellect of the population as a whole. Such a cross is undesirable, therefore, not only from a social view which everyone, particularly those in the South, readily sees but also from the biological or eugenic standpoint…

…One of the greatest dysgenic forces of both the past and the present is war. In the time of conflict the young and the most able men both physically and mentally are used in the army. By far the greater per cent of these men are either killed or seriously disabled. This leaves the weaklings to marry and bring forth the next generation. Not only is war a menace but also the preparation for war. Army and naval academies and the army service as well are factors in cutting down on the birth rate of the upper middle classes for the men, if they marry at all, marry rather late in life. War must be abolished…

Nigeria’s dangerous skin whitening obsession

Nigeria’s dangerous skin whitening obsession
 
Al Jazeera
2013-04-06

Mohammed Adow

Nigeria has the world’s highest percentage of women using skin lightening agents in the quest for “beauty”.

Lagos, Nigeria – After carefully washing her face, legs and arms, Taiwo Solomon vigorously rubs cream over her body. She is meticulous and makes sure she covers her entire face. Soloman, 32, is bleaching her skin. She believes fairer skin could be her ticket to a better life. So she spends her meager savings on cheap black-market concoctions that promise to lighten her pigment.

This has been a daily routine for the past 15 years. Now several shades lighter she says her new skin makes her feel more beautiful and confident.

“Bleaching just makes me feel special, like am walking around in a spotlight,” she told Al Jazeera. “I am not seeking to be totally white, I just want to look beautiful. I cannot stop using the lightening agents,” she adds.

Solomon is not alone. According to the World Health Organisation (WHO), 77 percent of women in Nigeria use skin-lightening products, the world’s highest percentage. That compares with 59 percent in Togo, and 27 percent in Senegal. The reasons for this are varied but most people say they use skin-lighteners because they want “white skin”.

In many parts of Africa, lighter-skinned women are considered more beautiful and are believed to be more successful and likely to find marriage.

It’s not only women though who are obsessed with bleaching their skins. Some men too are involved in the practice…

…Dangerous consequences

Skin bleaching comes with hazardous health consequences. The dangers associated with the use of toxic compounds for skin bleaching include blood cancers such as leukemia and cancers of the liver and kidneys as well as severe skin conditions.

Hardcore bleachers use illegal ointments containing toxins like mercury, a metal that blocks production of melanin, which gives the skin its colour, but can also be toxic…

The Genomic Revolution and Beliefs about Essential Racial Differences: A Backdoor to Eugenics?

The Genomic Revolution and Beliefs about Essential Racial Differences: A Backdoor to Eugenics?

Could the explosion of genetic research in recent decades affect our conceptions of race? In Backdoor to Eugenics, Duster argues that reports of specific racial differences in genetic bases of disease, in part because they are presented as objective facts whose social implications are not readily apparent, may heighten public belief in more pervasive racial differences. We tested this hypothesis with a multi-method study. A content analysis showed that news articles discussing racial differences in genetic bases of disease increased significantly between 1985 and 2008 and were significantly less likely than non–health-related articles about race and genetics to discuss social implications. A survey experiment conducted with a nationally representative sample of 559 adults found that a news-story vignette reporting a specific racial difference in genetic risk for heart attacks (the Backdoor Vignette) produced significantly greater belief in essential racial differences than did a vignette portraying race as a social construction or a no-vignette condition. The Backdoor Vignette produced beliefs in essential racial differences that were virtually identical to those produced by a vignette portraying race as a genetic reality. These results suggest that an unintended consequence of the genomic revolution may be the reinvigoration of age-old beliefs in essential racial differences.

Will Personalized Medicine Challenge or Reify Categories of Race and Ethnicity?

Will Personalized Medicine Challenge or Reify Categories of Race and Ethnicity?

In the last 5 years, medical geneticists have been conducting studies to examine possible links between DNA and disease on an unprecedented scale, using newly developed DNA genotyping and sequencing technologies to quickly search the genome. These techniques have also allowed researchers interested in human genetic variation to begin to catalogue the range of genetic similarities and differences that exist across individuals from around the world, through initiatives such as the International Haplotype Mapping Project. These studies of human genetic variation promise to produce new kinds of information about our DNA, but they have also raised ethical questions.

Early results from genome-wide studies of possible links between DNA and various medical conditions are being used by various actors to develop what they call “personalized medicine,” the effort to tailor and individualize diagnoses and treatments for use during routine medical care. The promises of personalized medicine are built on the idea that each individual’s genome is unique. They are also built on the idea that genetic variation among individuals will help explain differential susceptibilities to disease and why some patients respond better to some treatments than others. To this end, researchers have focused on characterizing genetic differences between individuals and groups…

…We note two ethical dilemmas posed by the claims made by these and other similar studies that attempt to link genetics, ancestry, and disease, particularly when ancestries are described in terms of continent of origin, for example, European, African, and Asian. Such labels are based on socioculturally defined U.S. categories of race and ethnicity, such as white, black, and Asian. The first dilemma arises because these studies are based on a relatively small subset of individuals who identify within any of these continental ancestry or race groupings. Thus, any extension of study findings to others who identify within these broad groupings would be fraught with problems of accuracy and precision. Indeed, much genetic evidence suggests that those who identify with a particular U.S. race or ethnicity census category are quite genetically heterogeneous. Thus, there is no neat correspondence between genetic variation and one’s assumed race or ethnicity. Indeed, no single pattern of genetic variation is diagnostic of affiliation with any particular race or ethnicity.

Second, and consequently, many worry that the new technologies being used to develop personalized medicine may also become technologies that are used to define “genetic signatures” for, or “genetic stereotyping” of, different racial or ethnic groups. This aspect of personalized medicine, if developed and nurtured into broader clinical use, will popularize the idea that it is possible to infer underlying genetic makeup from an observer-defined or self-reported race or ethnicity, when even proponents of using race in genetics research argue that this is a logical fallacy. This possibility recalls some of the past attempts to link race and biology, e.g., the eugenics movements of the early twentieth century…

…Nor is race new to American medical genetics. Many scholars have analyzed the American eugenics movements of the early twentieth century and the more ethically aware field of medical genetics that they eventually gave rise to in the mid-twentieth century. Prior to the start of the Human Genome Project, medical genetics focused primarily on relatively rare, familially inherited diseases. Certain generalizations about the relationships between race and genetics, now part of popular understanding and medical training programs, grew out of these studies. For example, medical school and college biology curricula continue to propagate the idea that some single-gene, highly heritable diseases, like Tay-Sachs disease or sickle-cell anemia, are prevalent in only certain groups—as in Jewish and African American groups, respectively—than other groups. What is often not acknowledged is that Tay-Sachs has also been observed at high prevalence in non-Jewish groups in Quebec, Canada and that sickle-cell and other hemoglobin disorders are common in many groups around the world. The misconception that a particular disease like sickle-cell is specific to African Americans may lead to patients being misdiagnosed or diagnosed too late in the progression of disease simply because they are not of the ethnic group “marked” by the disease…

…Personalized medicine is at a crossroads. It may be used to sustain old beliefs about racial differences, yoking them to supposed differences in health and susceptibilities to illness. This in turn may fuel the view that our genetics establishes an innate, definitive roadmap of our future health. However, recent studies of hundreds of common complex diseases suggest that genetics has only a small part to do with our susceptibilities to these diseases.

An alternative route for personalized medicine is for its practitioners to take stock of the various environmental onslaughts that individuals are subjected to and tailor medical diagnoses and treatments by considering each patient’s unique complement of environmental and biological factors that may contribute to health or disease. If personalized medicine is to bear out its name and become truly “personalized,” then a focus on racial differences at the level of the genome constitutes a step off the path with many ramifications, including the possibility of racial and ethnic stereotyping and discrimination during routine medical care that could lead to misdiagnoses and ineffective treatment regimens. Efforts to achieve personalized medicine in clinical settings would do better to focus on patterns in genomes and how such patterns may be associated with disease, rather than trying to find genetic correlates for existing racial and ethnic categories…

The Elusive Variability of Race

The Elusive Variability of Race

GeneWatch
Council for Responsible Genetics
Volume 21, Issue 3-4 (July-August 2009)

Pages 4-6

Patricia J. Williams, James L. Dohr Professor of Law
Columbia University

The question of race is, at its core, a questioning of humanity itself.  In various eras and locales, race has been marked by color of skin, texture of hair, dress, musical prowess, digital dexterity, rote memorization, mien, mannerisms, disease, athletic ability, capacity to write poetry, sense of rhythm, sobriety, childlike cheerfulness, animal anger, language, continent of origin, hypodescent, hyperdescent, religious affiliation, thrift, flamboyance, slyness, physical size, or presence of a moral conscience. These presumed markers may appear random in the aggregate, but they have nevertheless been deployed to rationalize the distribution of resources and rights to some groups and not others. Behind the concept of race, in other words, is a deeper interrogation of what distinguishes beasts from brothers;  of who is presumed entitled or dispossessed,  person or slave, autonomous or alien, compatriot or enemy.

In the contemporary United States, race is based chiefly on broad and variously calibrated metrics of African ancestry. To get a full sense of the ideological incoherence of race and racism, however, one must also include the longer history: the centuries-old Chinese condescension to native Taiwanese Islanders; the English derogation of the Irish for “pug noses”; the plight of the Dalit (i.e., untouchables) in India; or comprehensively eugenic regimes like Hitler’s.

Despite the enormous definitional diversity of what race even means, and despite the fact that the biological studies – from Charles Darwin’s observations to the Human Genome Project – have patiently, repetitively and definitively shown that all humans are a single species, there remain many determined to reinscribe a multitude of old racialist superstitions onto the biotechnologies of the future.  Despite the biological evidence – and a towering body of social science that is cumulative (observations over time), comprehensive (multiple levels of inquiry) and convergent (from a variety of sources, places, disciplines) – we are still asking the same centuries-old questions…

…So what is race if not biology?

Race is a hierarchical social construct that assigns human value and group power. Social constructions are human inventions, the products of mind and circumstance. This is not to say that they are imaginary. Racialized taxonomies have real consequences upon biological functions, including the expression of genes. They affect the material conditions of survival-relative respect and privilege, education, wealth or poverty, diet, medical and dental care, birth control, housing options and degree of stigma…

…If history has shown us anything, it’s that race is contradictory and unstable. Yet our linguistically embedded notions of race seem to be on the verge of transposing themselves yet again into a context where genetic percentages act as the ciphers for culture and status, as well as economic and political attributes. In another generation or two, the privileges of whiteness may be extended to those who are “half” this or that.  Indeed, some of the discussions about Barack Obama’s “biracialism” seemed to invite precisely such an interpretation. Let us not mistake it for anything like progress, however: biracialism always has a short shelf life. For example, by the time he was elected President, Barack Obama was no longer our first “half and half president” but had become all African-American all the time. Indeed, Obama himself seemed to acknowledge the more complex reality of his own lineage in an off-the-cuff aside, when, speaking about his daughters’ search for a puppy, he observed that most shelter dogs are “mutts like me.”

In fact, of course, we’re all mutts – and as Americans, we’ve been mixing it up faster and more thoroughly than anyplace on earth. At the same time, we live in a state of tremendous denial about the rambunctiousness of our recent lineage. The language by which we assign racial category narrows or expands our perception of who is more like whom, tells us who can be considered marriageable or untouchable. The habit of burying the relentlessly polyglot nature of our American identity renders us blind to how intimately we are tied as kin.

In the United States’ vexed history of color-consciousness, anti-miscegenation laws (the last of which were struck down only in 1967) enshrined the notion of hypodescent. Hypodescent is a cultural phenomenon whereby the child of parents who come from differing social classes will be assigned the status of the parent with the lower standing. Most parts of the Deep South adhered to it with great rigidity, in what is commonly called the “one drop and you’re black” rule. Take for example, New York Times editor Anatole Broyard, who denied any relation to his darker-skinned siblings and “passed” as white for most of his adult life. There were many who expressed shock when it was uncovered that he was “really” black. Some states, like Louisiana, practiced a more gradated form of hypodescent, indicating hierarchies of status with vocabulary like “mulatto,” “quadroon,” and “octaroon.” And even today, despite our diasporic, fragmented, postmodern cosmopolitanism, there is a thoughtless or unconscious tendency to preserve these taxonomies, no matter how incoherent. Consider Essie Mae Washington-Williams, the daughter Senator Strom Thurmond had by his family’s black maid. She lived her life as a “Negro,” then as an “African American,” and attended an “all-black” college. But in her 70s, when Thurmond’s paternity became publicized, she was suddenly redesignated “biracial.” Tiger Woods and Kimora Lee Simmons are alternatively thought of as African-American or “biracial,” but rarely as “Asian-American.”

In contrast, many parts of Latin America, like Brazil or Mexico, assign race by the opposite process, hyperdescent. That’s when those with any ancestry of the dominant social group, such as European, identify themselves as European or white, when they may also have African or Indian parents. As more Latinos have become citizens of the United States, we have interesting examples of this cultural cognitive dissonance: Just think about Beyoncé Knowles and Jennifer Lopez. Phenotypically they look very similar. Yet Knowles is generally referred to as black or African-American; Lopez is generally thought of as white (particularly among her Latino fan base) or Latina (among the rest of us), but she is never called black or even biracial…

Professor Roberts will be discussing her latest project in connection with the “Understanding Race” theme semester. In “Fatal Invention: How Science, Politics, and Big Business Re-create Race in the Twenty-First Century” she argues that America is experiencing a dangerous resurgence of classifying populations into biological races. By searching for differences at the molecular level, a new race-based science is obscuring racism in our society and legitimizing state brutality against communities of color at a time when many claim that the United States is “post-racial.” Moving from an account of the evolution of the concept of race—proving that it has always been a mutable and socially defined political division supported by mainstream science—Roberts delves deeply into the current debates, interrogating cutting-edge genomic science and biotechnology, interviewing its researchers, and exposing the political consequences of the focus on race-based genetic difference. Fatal Invention is a powerful call for us to affirm our common humanity by eliminating the social inequities preserved by the political system of race…

In Race in a Bottle, Jonathan Kahn tracks the contentious history of BiDil, the first drug targeted specifically to African Americans. Ironically, race-based drug treatment emerged in the wake of the sequencing of the human genome, a project that theoretically promised both to scientifically refute the notion of genetically distinct racial groups and to usher in an era of personalized medicine. Though hyped by researchers, the FDA, and the press as an important first step toward personalized medicine, BiDil is a drug administered to patients based on their membership in a group…

…Critical to Kahn’s argument regarding evidence is the fact that the clinical trials on which the company based its patent application for BiDil were never designed to compare racial difference in response to the drug. Using “care of the data” as an organizing theme, Kahn highlights one of the many troubling aspects of this controversy: the extraordinarily loose, if not sloppy, construction of what passed as evidence in the patent application and FDA hearings. From the use of misleading statistics on mortality from heart failure in African Americans, to the failure to define the central variable of race, to the design of a clinical trial (A-HeFT) that included only African Americans (and therefore could not determine differential efficacy) to the lack of any mechanistic understanding for a differential effect, Kahn shows that attention to the data was consistently problematic when it came to matters of race. The chapter on the FDA hearings is particularly illuminating…
