Unpunished and Unreformed
Michael S. Bryant's Confronting the "Good Death" is a legal history of the postwar Nazi euthanasia trials conducted from 1945 until 1953 by U.S. and German courts in what would become the Federal Republic of Germany. In the Nazi context, euthanasia, of course, meant the murder of mentally and physically ill people without their request or consent. Meaningful legal confrontation after the war, Bryant shows, was short-lived and seriously flawed. His thesis is that the reason for the failure of various courts to punish the killers lies in the fact that "[f]or both Americans and West Germans, concerns about preserving or recuperating sovereign power consistently bedeviled the neutral quest for justice" (p. 2).
In the first chapter, Bryant provides a concise history of the Nazi euthanasia program and its administration. The chapter begins by describing the ways in which competition for scarce material and human resources during the First World War devalued the lives of mental patients, and extends beyond the Nazi killing of the mentally ill and weak to the elimination of any "life unworthy of life," including German women traumatized by allied bombing, tubercular Russian laborers, Jews, and Gypsies. This background chapter, based on existing historiography, emphasizes continuities in personnel, technologies of killing, victim control techniques, and rationalization processes that extended the moral possibility of mass murder from euthanasia to the Holocaust.
Bryant underscores the economic rationale behind the destruction of those who euthanasia proponents regarded as "useless eaters." This was indeed a critical consideration, particularly in connection with allocating resources in anticipation for and during war. However, since both the allied and German courts took pains to consider the motivations behind the perpetrators' actions, it would have been helpful if Bryant had given more attention to the larger racial ideology behind eugenics. The mentally ill and retarded were deemed not only useless, but also genetically dangerous, and this was important to the medical killers who saw themselves as physicians to the nation first and to the individual patient only secondly. Racial ideology, not merely "uselessness," was even more of a factor in the deaths of other groups that Nazis marked for mass murder. A more extensive treatment of ideological motives could have set the stage for a useful discussion of comparisons between racial hygiene programs targeting "worthless" Germans and those aimed at perceived racial outsiders. Most outsider groups were, as Bryant points out, able-minded and able-bodied who could, and often did, contribute useful work to the Nazis and their war effort.
Bryant's own research forms the basis of chapters 2 through 5, which treat the U.S. euthanasia trials from 1945 through 1947 and the German trials in three different phases from 1946 through 1953. The study focuses narrowly on a close reading of the texts created by the trials themselves--transcripts and verdicts--in search of evidence of extrajudicial influences on their outcomes.
Bryant describes two sets of U.S. euthanasia trials. The United States Army conducted the first set in October 1945 against members of the medical staff of the Hadmar killing center in Hesse-Nassau. The second set was part of the Nuremberg medical trials between November 1946 and August 1947. In both instances, the defendants were charged with war crimes, crimes against peace, and crimes against humanity. The last category was not defined until the Allies created and agreed to the London Charter in August 1945. Unlike German courts that began trying euthanasia cases in 1946, U.S. courts apparently had few qualms about invoking an ex post facto law against Nazi murderers. However, they were extremely hesitant to put Germany's internal domestic affairs on trial, because, Bryant claims, they did not want to establish a precedent that in the future could subject the United States to a similar international tribunal which would undermine its sovereignty. To get around the sovereignty issue, the United States interpreted euthanasia (as well as other National Socialist atrocities) as an extension of aggressive war by claiming that disabled persons were killed in order to dedicate medical supplies, hospital spaces, and personnel to a grand plan of subjugating the people of Europe. To attach this war-related motive to individual perpetrators, they then adopted the questionable tactic of holding all members of criminal organizations (like the Nazi Party) jointly and severally liable for the same grand conspiracy against peace.
Bryant's thesis is difficult to prove with the types of sources he uses. None of the trial records or the correspondence between various actors actually states that the main reason for the circuitous prosecution strategies chosen was to preserve or regain state sovereignty. However, it is plausible enough in the American case, given the U.S. history of avoiding such challenges to its autonomy from international organizations. It is less convincing for the Germany, where there were simply too many additional motives, and too many personal and group interests militating against conviction to assign precedence to national sovereignty. Among other factors, the author lists confusion over investigative and court jurisdictions, statutes of limitations, the feeling among many Germans that Allied war crime trials were enforcing a mere "victor's justice," the desire of both Germans and Americans to tie Germany firmly to the West during the Cold War, and Konrad Adenauer's insistence on reintegrating former Nazis into the German civil service, including the judiciary.
Reservations aside, Confronting the "Good Death" is an important book that deserves a wide readership. Despite the fact that Americans and Germans started out determined to see Nazi atrocities revealed and punished, both quickly abandoned vigorous prosecution. The contorted legal logic that ultimately led courts to exonerate and even commend men and women, who in some cases had murdered hundreds of helpless patients with their own hands, is astounding. Anyone interested in broad issues surrounding the administration of international justice; medical ethics; human rights; tensions between morality, law, and politics; or the ways that societies retrospectively deal with wartime atrocities will find a compelling case study in Bryant's work.

Race? Debunking a Scientific Myth - Book
Race? Debunking a Scientific Myth
Ian Tattersall and Rob DeSalle
Race has provided the rationale and excuse for some of the worst atrocities in human history. Yet, according to many biologists, physical anthropologists, and geneticists, there is no valid scientific justification for the concept of race.
To be more precise, although there is clearly some physical basis for the variations that underlie perceptions of race, clear boundaries among “races” remain highly elusive from a purely biological standpoint. Differences among human populations that people intuitively view as “racial” are not only superficial but are also of astonishingly recent origin.
In this intriguing and highly accessible book, physical anthropologist Ian Tattersall and geneticist Rob DeSalle, both senior scholars from the American Museum of Natural History, explain what human races actually are—and are not—and place them within the wider perspective of natural diversity. They explain that the relative isolation of local populations of the newly evolved human species during the last Ice Age—when Homo sapiens was spreading across the world from an African point of origin—has now begun to reverse itself, as differentiated human populations come back into contact and interbreed. Indeed, the authors suggest that all of the variety seen outside of Africa seems to have both accumulated and started reintegrating within only the last 50,000 or 60,000 years—the blink of an eye, from an evolutionary perspective.
The overarching message of Race? Debunking a Scientific Myth is that scientifically speaking, there is nothing special about racial variation within the human species. These distinctions result from the working of entirely mundane evolutionary processes, such as those encountered in other organisms.
IAN TATTERSALL, curator emeritus in the American Museum of Natural History, is also the author of Paleontology: A Brief History of Life (Templeton Press, 2010), The Fossil Trail: How We Know What We Think We Know about Human Evolution (Oxford University Press, 2009), and The World from Beginnings to 4000 BCE (Oxford University Press, 2008).
ROB DESALLE is a curator at the American Museum of Natural History in the Sackler Institute for Comparative Genomics. He curated the American Museum of Natural History’s new Hall of Human Origins (2006) and has written more than 300 peer-reviewed scientific publications and several books. Tattersall and DeSalle recently coauthored Human Origins: What Bones and Genomes Tell Us about Ourselves (Texas A&M University Press, 2007).
What Readers Are Saying:
"In the footsteps of Haddon and Huxley, a prominent anthropologist and a prominent evolutionary geneticist have teamed up to give us a powerful scientific critique of the commonsensical idea of race. Distinguished scholars and skilled communicators, Ian Tattersall and Rob DeSalle show clearly how “race” simply cannot be used as a synonym for “human biological diversity”. In the age of genomics, this partnership of intellectual specialties is particularly valuable, and the result is a splendid testament to the merits of trans-disciplinary collaborations."--Jon Marks, Department of Anthropology, University of North Carolina-Charlotte
"If you think you understand what 'race' is, read this book!"--Ian Paulsen, Birdbooker Report, The Guardian
"Tattersall and DeSalle argue that not only are the differences between the classically defined "races" very superficial, they are also of suprisingly recent origin...The diversity among us has risen in a blink of evolution's eye...began to reverse as formerly isolated human groups came back into contact and interbred...Tattersall and DeSalle confront those industries head on and in no uncertain terms, arguing that "race-based medicene" and "race-based genomics" are deeply flawed."--Jan Sapp, professor in the biology department at York University in Toronto, American Scientist
"This well-written, enjoyable book should be suitable for a broad range of readers interested in human diversity, its origins, and its future."--S.D. Stout, Choice
"Race? is an accessible primer on much of the biological theory relevant to the question of race...this book appeals to both general readers and students of biology, anthropology, and the history and philosophy of science as a valuable, if incomplete, overview of the topic's major themes."--Paul Mitchell, Expedition
"In Race? Debunking a Scientific Myth, they [the authors] dismantle the biological notion of race...the authors argue that a valid justification for the concept of race does not exist...that all the variations we characterize as 'racial' accumulated over a relatively short time span...an informative, well-researched, and well-written contribution to the scientific, intellectual (and even mundane) discourse on the lingering problem of race."--Okori Uneke, International Social Science Review
"This is a helpful book for anyone who wants a short, accurate and scholarly appraisal of race as a concept . . . Students in both anthropology and human genetic courses will benefit from the discussions this book will provide."--Quarterly Review of Biology
“Tattersall and DeSalle expertly and clearly summarize the scientific findings that provide the best evidence about the insignificance of race. They also survey, usefully and succinctly, the history of ideas about race from the Enlightenment through the genome project. Summarizing current biological and archaeological work, Tattersall and DeSalle note that all humans have a genetic make-up nearly 100 percent African in Origin.” — Victorian Studies

Race Finished - Jan Sapp
Race Finished. Jan Sapp
RACE?: Debunking a Scientific Myth. Ian Tattersall and Rob DeSalle. xviii + 226 pp. Texas A&M University Press, 2011. $35.
RACE AND THE GENETIC REVOLUTION: Science, Myth, and Culture. Edited by Sheldon Krimsky and Kathleen Sloan. xiv + 296 pp. Columbia University Press, 2011. $105 cloth, $35 paper.
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 there simply is no valid biological basis for the concept.
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 be inferior or superior in some way.
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 geographical populations in the course of human evolution does not compare to the variation among individuals. “Since such racial classification is now seen to be of virtually no genetic or taxonomic significance either, no justification can be offered for its continuance,” Lewontin concluded.
Further research has supported that conclusion. In 2000, at a White House event celebrating their completion of the first draft of the 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 the American Museum of Natural History. Their aim is to explain human diversity in terms of human evolution and dispersal since our ancestors walked out of Africa some 100,000 years ago. The patterns of diversity, they write, reflect the processes of divergence and reintegration, the yin and yang of evolution.
In biology, a grouping has biological meaning based on principles of common descent—the Darwinian idea that all members of the group share a common ancestry. On this basis, and on the ability to interbreed, all humans are grouped into one species as Homo sapiens, the only surviving member of the various species that the genus comprised. Species are arranged within the “tree of life,” a hierarchical classification that situates each species in only one genus, that genus only in one family and so on. Nothing confuses that classification more than the exchange of genes between groups. In the bacterial world, for example, gene sharing can occur throughout the most evolutionarily divergent groups. The result is a reticulate evolution—a global net or web of related organisms, and no species. Among humans, reticulation occurs when there is interbreeding within the species—mating among individuals from different geographical populations. The result of such genetic mixing 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 reintegrate within the past 50,000 to 60,000 years. The diversity among 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 intermittently throughout human history, is sped up today because of 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 American Society of Human Genetics in 2008.
Nowhere is the need for new government regulations more evident than in the collection, use and storage of DNA for forensic purposes, all of which have increased dramatically over the past two decades. In the chapter opening a section devoted to this subject, Michael T. Risher, staff attorney at the American Civil Liberties Union of Northern California, explains that in California suspected felons are required to give DNA samples. About 30 percent of those suspects are not convicted; whether they are convicted or not, their DNA profile remains in the database, making them “potential suspects whenever DNA is recovered from a crime scene.” A disproportionate number of those innocent people whose DNA is stored are people of color.
The same holds for Britain, as Helen Wallace, director of the advocacy group GeneWatch UK, explains. Six percent of the white population of Britain has records in the country’s DNA database. In contrast, Wallace writes, “approximately 27 percent of the entire black population, 42 percent of the male black population, 77 percent of young black men and 9 percent of all Asians have records on the National DNA Database.” An estimated 55 percent of these people have not been charged or convicted of any offense. The retention of DNA from everyone who has been arrested raises important privacy and civil-rights concerns, Wallace notes. The creation of a permanent “list of suspects” has the potential for various abuses and misuses. The practice may result in “the exacerbation of discrimination in the criminal justice system,” she writes.
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.
The second problem with racialized medicine is that it tends to overlook the evidence that discrimination, poverty, stress and restricted access to education and health care underlie the health disparities between ethnic groups in the United States. High blood pressure may be as much a social disease as a biological one. Graves notes that the U.S. National Institutes of Health allocates $2.7 billion per year for health-disparity research, much of which is based on the assumption that ethnic-minority populations are genetically predisposed to specific complex diseases. Graves argues that until this “false paradigm” that focuses on genes instead of social causes of diseases is toppled, “much of this research is following a fool’s errand.” There is no pill we can take to cure social disorders, but genetic-testing technologies may provide insight into an individual’s predisposition for a disease and the optimal use of certain drugs. Racialized medicine needs to be replaced by sound “evolutionary medicine,” based on ancestral geographic origins, socioeconomic status 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.

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 reintegrate within the past 50,000 to 60,000 years. The diversity among 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 intermittently throughout human history, is sped up today because of 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 American Society of Human Genetics in 2008.
Nowhere is the need for new government regulations more evident than in the collection, use and storage of DNA for forensic purposes, all of which have increased dramatically over the past two decades. In the chapter opening a section devoted to this subject, Michael T. Risher, staff attorney at the American Civil Liberties Union of Northern California, explains that in California suspected felons are required to give DNA samples. About 30 percent of those suspects are not convicted; whether they are convicted or not, their DNA profile remains in the database, making them “potential suspects whenever DNA is recovered from a crime scene.” A disproportionate number of those innocent people whose DNA is stored are people of color.
The same holds for Britain, as Helen Wallace, director of the advocacy group GeneWatch UK, explains. Six percent of the white population of Britain has records in the country’s DNA database. In contrast, Wallace writes, “approximately 27 percent of the entire black population, 42 percent of the male black population, 77 percent of young black men and 9 percent of all Asians have records on the National DNA Database.” An estimated 55 percent of these people have not been charged or convicted of any offense. The retention of DNA from everyone who has been arrested raises important privacy and civil-rights concerns, Wallace notes. The creation of a permanent “list of suspects” has the potential for various abuses and misuses. The practice may result in “the exacerbation of discrimination in the criminal justice system,” she writes.
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.As an example, he considers the drug called BiDil, FDA approved as an anti–heart-attack agent specifically marketed to African Americans on the grounds that they have a biological propensity for heart disease brought on by high blood pressure. Not only is the drug not effective for all African Americans, it is quite effective for many individuals who self-identify as Caucasian.
The second problem with racialized medicine is that it tends to overlook the evidence that discrimination, poverty, stress and restricted access to education and health care underlie the health disparities between ethnic groups in the United States. High blood pressure may be as much a social disease as a biological one. Graves notes that the U.S. National Institutes of Health allocates $2.7 billion per year for health-disparity research, much of which is based on the assumption that ethnic-minority populations are genetically predisposed to specific complex diseases. Graves argues that until this “false paradigm” that focuses on genes instead of social causes of diseases is toppled, “much of this research is following a fool’s errand.” There is no pill we can take to cure social disorders, but genetic-testing technologies may provide insight into an individual’s predisposition for a disease and the optimal use of certain drugs. Racialized medicine needs to be replaced by sound “evolutionary medicine,” based on ancestral geographic origins, socioeconomic status 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.
