The Nature of Race Book. Submitted to Open Behavioral Genetics December 25, 2014 Published in Open Behavioral Genetics June 20, 2015 The Nature of Race John Fuerst1 Abstract: Racial constructionists, anti-naturalists, and anti-realists have challenged users of the biological race concept to provide and defend, from the perspective of biology, biological philosophy, and ethics, a biologically informed concept of race. In this paper, an onto- epistemology of biology is developed. What it is, by this, to be "biological real" and "biologically meaningful" and to represent a "biological natural division" is explained. Early 18th century race concepts are discussed in detail and are shown to be both sensible and not greatly dissimilar to modern concepts. A general biological race concept (GBRC) is developed. It is explained what the GBRC does and does not entail and how this concept unifies the plethora of specific ones, past and present. Other race concepts as developed in the philosophical literature are discussed in relation to the GBRC. The sense in which races are both real and natural is explained. Racial essentialism of the relational sort is shown to be coherent. Next, the GBRC is discussed in relation to anthropological discourse. Traditional human racial classifications are defended from common criticisms: historical incoherence, arbitrariness, cluster discordance, etc. Whether or not these traditional human races could qualify as taxa subspecies – or even species – is considered. It is argued that they could qualify as taxa subspecies by liberal readings of conventional standards. Further, it is pointed out that some species concepts potentially allow certain human populations to be designated as species. It is explained why, by conventional population genetic and statistical standards, genetic differences between major human racial groups are at least moderate. Behavioral genetic differences associated with human races are discussed in general and in specific. The matter of race differences in cognitive ability is briefly considered. Finally, the race concept is defended from various criticisms. First, logical and empirical critiques are dissected. These include: biological scientific, sociological, ontological, onto-epistemological, semantic, and teleological arguments. None are found to have any merit. Second, moral-based arguments are investigated in context to a general ethical frame and are counter-critiqued. Racial inequality, racial nepotism, and the “Racial Worldview" are discussed. What is dubbed the Anti-Racial Worldview is rejected on both empirical and moral grounds. Finally, an area of future investigation – the politics of the destruction of the race concept – is pointed to.

It is infrequently acknowledged that the first through fourth statements can not all be true at the same time: if "race" is meaningless, it makes no sense to say that it is non-biological; if it is non- biological, it can not exist in nonhuman animals; and so on and so forth. Nevertheless, these four contrary claims, individually flawed as they are, are thought by many to constitute, in composite, an ironclad argument against any attempt to characterize certain divisions of Homo sapiens as biological races. (Presumably it is not yet considered „scientifically racist' to study biodiversity in other animal species, though we can not be sure. 2) There is, of course, an element of truth to all four of the stated claims: the word “race” indeed has no unique definition; anyone can deem that whatever genetically based differences exist between human populations are unimportant; there are race concepts which are fundamentally non-biological; and there are biological race concepts (frequently made of straw) by which there are no human biological races. All of this is true, and rather trivial, but since the statements are so often taken to mean something true and nontrivial – that there is no robust sense in which human biological races exist - we feel compelled to provide a precise conceptual framework for biological race. 2We use single quotes to signify that a term is unclear; some of the quoted passages, however, use double quotes to signify the same. We use double quotes to call to attention that we are referring to a term, not a concept. 4 Still, in the same way as we classify races and degenerations of horses and poultry, of pinks and tulips, so also, in addition, must we classify the varieties of mankind – Blumenbach (1806) I. Biology – A Philosophical Clarification I-A. Existing Views: Confusions Abound We must start by carving out a conceptual space for biologically real race. Regarding the panoply of existing views on race (and its biological reality, if any), we must confess to deep confusion. The least bewildering account may be that of philosopher Quayshawn Spencer (2012), which we quote simply to give a sense of the depths into which we are getting: Historically, “biological racial realism” has been interpreted in either one of two ways. One is “race is a natural kind in biology,” and the second is “race is a real biological kind.” However, race theorists adopt at least four different views about what a natural kind is. Let me begin with the natural kind views. First, some race theorists – such as Anthony Appiah (1996, 40), Robin Andreasen (2000, S655- S657), and Naomi Zack (2002, 4) – define a natural kind as an objectively real kind. A paradigm example is Andreasen‟s view. According to Andreasen (2000, S655), race must be a “natural kind” in order to be biologically real… Second, some race theorists – such as Edouard Machery (2005, 446) and Glasgow (2009, 81) – define a natural kind as an inductively useful kind in science. For example, Machery (2005, 445, 446)

  • Religion, Homosexuality, and Collisions of Liberty and Equality in American Public Law
    A Jurisprudence of "Coming Out": Religion, Homosexuality, and Collisions of Liberty and Equality in American Public Law William N. Eskridge, Jr.! Conflicts among religious and ethnic groups have scored American cultural and political history. Some of these conflicts have involved campaigns of suppression against deviant religious and minority ethnic groups by the mainstream. Although the law has most often been deployed as an instrument of suppression, there is now a public law consensus to preserve and protect the autonomy of religious and ethnic subcultures, as well as the ability of their members to self-identify without penalty. One thesis of this Essay is that this vaunted public law consensus should be extended to sexual orientation minorities as well. Like religion, sexual orientation marks both personal identity and social divisions.' In this century, in fact, sexual orientation has steadily been replacing religion as the identity characteristic that is both physically invisible and morally polarizing. In 1900, one's group identity was largely defined by one's ethnicity, social class, sex, and religion. The norm was Anglo-Saxon, middle-class, male, and Protestant. The Jew, Roman Catholic, or Jehovah's Witness was considered deviant and was subject to social, economic, and political discrimination. In 2000, one's group identity will be largely defined by one's race, income, sex, and sexual orientation. The norm will be white, middle-income, male, and heterosexual. The lesbian, gay man, or transgendered person will be considered deviant and will be subject to social, economic, and political discrimination. t Professor of Law, Georgetown University Law Center. An earlier draft of this Essay was presented at workshops held at the Georgetown University Law Center.

  • Lysenkoism: the Danger of Political Correctness Emily G. Badger
    Badger !0 Lysenkoism: The Danger of Political Correctness Emily G. Badger Senior Division Historical Paper Paper Length: 2,334 words Badger !1 What is truth? A simple definition of truth would be anything that can be tested and proven in a universal process, for example, the scientific method. What happens in an environment where truth is not allowed to be tested? What would the consequences be? Unfortunately, there was a time in history when this was true, and it was strikingly recent. In the late 1920’s Mendelian genetics were replaced by Lysenkoism in Soviet Russia, just before the start of World War II. Though the conflict started as a dispute of truth within scientific circles, it quickly became evident that Lysenko’s underlying motive was not to make scientific discoveries, but to gain political power. The tragic result of politically correct truth replacing scientific truth was mass starvation and ultimately the crippling of a world superpower. To understand how such a catastrophic event could occur, it is necessary to understand the political climate of the Soviet Union at the time. First, it is important to note that Russia was a communist state, which meant there was an intense hatred of anyone who was considered bourgeois, a member of the middle class who upheld the interests of capitalism rather than communism (Collins English Dictionary). Bourgeois members of Russian society were hated because they were property owners; they were not considered to be working for a living and thus were the enemy of Communism. Being called bourgeois in Russia at this time was essentially a death sentence, as those who disagreed with Communist values were “removed” by the government.

    ANTHROPOLOGICAL PAPERS OF THE AMERICAN MUSEUM OF NATURAL HISTORY VOLUME XXIII NEW YORK PUBLISHED BY ORDER OF THE TRUSTEES 1925 Editor CLARK WISSLER FOREWORD Louis ROBERT SULLIVAN Since this volume is largely the work of the late Louis Robert Sulli- van, a biographical sketch of this able anthropologist, will seem a fitting foreword. Louis Robert Sullivan was born at Houlton, Maine, May 21, 1892. He was educated in the public schools of Houlton and was graduated from Bates College, Lewiston, Maine, in 1914. During the following academic year he taught in a high school and on November 24, 1915, he married Bessie Pearl Pathers of Lewiston, Maine. He entered Brown University as a graduate student and was assistant in zoology under Professor H. E. Walters, and in 1916 received the degree of master of arts. From Brown University Mr. Sullivan came to the American Mu- seum of Natural History, as assistant in physical anthropology, and during the first years of his connection with the Museum he laid the foundations for his future work in human biology, by training in general anatomy with Doctor William K. Gregory and Professor George S. Huntington and in general anthropology with Professor Franz Boas. From the very beginning, he showed an aptitude for research and he had not been long at the Museum ere he had published several important papers. These activities were interrupted by our entrance into the World War. Mr. Sullivan was appointed a First Lieutenant in the Section of Anthropology, Surgeon-General's Office in 1918, and while on duty at headquarters asisted in the compilation of the reports on Defects found in Drafted Men and Army Anthropology.

DOI: https://doi.org/10.25222/larr.300 OTHER ARTS AND HUMANITIES Blackface at the Andean Fiesta: Performing Blackness in the Danza de Caporales Danielle Roper University of Chicago, US [email protected] This study assesses the deployment of blackface in a performance of the Danza de Caporales at La Fiesta de la Virgen de la Candelaria in Puno, Peru, by the performance troupe Sambos Illimani con Sentimiento y Devoción. Since blackface is so widely associated with the nineteenth- century US blackface minstrel tradition, this article develops the concept of “hemispheric blackface” to expand common understandings of the form. It historicizes Sambos’ deployment of blackface within an Andean performance tradition known as the Tundique, and then traces the way multiple hemispheric performance traditions can converge in a single blackface act. It underscores the amorphous nature of blackface itself and critically assesses its role in producing anti-blackness in the performance. Este ensayo analiza el uso de “blackface” (literalmente, cara negra: término que designa el uso de maquillaje negro cubriendo un rostro de piel más pálida) en la Danza de Caporales puesta en escena por el grupo Sambos Illimani con Sentimiento y Devoción que tuvo lugar en la fiesta de la Virgen de la Candelaria en Puno, Perú. Ya que el “blackface” es frecuentemente asociado a una tradición estadounidense del siglo XIX, este artículo desarrolla el concepto de “hemispheric blackface” (cara-negra hemisférica) para dar cuenta de elementos comunes en este género escénico.

R. solanacearum race 3 biovar 2 occurs in highlands in the tropics and in subtropical and some warm-temperate areas throughout the world. It has also occurred in cold-temperate regions in Europe, where several outbreaks of brown rot of potato have been reported in the last 30 years. It has been reported in more than 30 countries and almost all continents. In the United States, several introductions of R. solanacearum race 3 biovar 2 have already occurred as a result of importation of infested geranium cuttings from off-shore production sites, but the pathogen was apparently eradicated. However, because of the risk of its possible re-introduction through importation of infected plant material, and its potential to affect potato production in cold-temperate areas in the northern United States, R. solanacearum race 3 biovar 2 is considered a serious threat to the United States potato industry.

  • Race Categorization and the Regulation of Business and Science
    617 Race Categorization and the Regulation of Business and Science Catherine Lee John D. Skrentny Despite the lack of consensus regarding the meaning or significance of race or ethnicity amongst scientists and the lay public, there are legal requirements and guidelines that dictate the collection of racial and ethnic data across a range of institutions. Legal regulations are typically created through a political process and then face varying kinds of resistance when the state tries to implement them. We explore the nature of this opposition by comparing responses from businesses, scientists, and science-oriented businesses (phar- maceutical and biotechnology companies) to U.S. state regulations that used politically derived racial categorizations, originally created to pursue civil rights goals. We argue that insights from cultural sociology regarding insti- tutional and cultural boundaries can aid understanding of the nature of re- sistance to regulation. The Food and Drug Administration’s guidelines for research by pharmaceutical companies imposed race categories on science- based businesses, leading to objections that emphasized the autonomy and validity of science. In contrast, similar race categories regulating first business by the Equal Employment Opportunity Commission (EEOC) and later scien- tific research sponsored by the National Institutes of Health (NIH) encoun- tered little challenge. We argue that pharmaceutical companies had the motive (profit) that NIH-supported scientists lacked and a legitimate discourse (boundary work of science) that businesses regulated by the EEOC did not have. The study suggests the utility of a comparative cultural sociology of the politics of legal regulation, particularly when understanding race-related reg- ulation and the importance of examining legal regulations for exploring how the meaning of race or ethnicity are contested and constructed in law.

Classical models of the spatial structure of population genetics rely on the assumption of migration-drift equilibrium, which is seldom met in natural populations having only recently colonized their current range (e.g., postglacial). Population structure then depicts historical events, and counfounding effects due to recent secondary contact between recently differentiated lineages can further counfound analyses of association between geographic and genetic distances. Mitochondrial polymorphisms have revealed the existence of two closely related lineages of the lake cisco, Coregonus artedi, whose signi®cantly different but overlaping geographical distributions provided a weak signal of past range fragmentation blurred by putative subsequent extensive secondary contacts. In this study, we analyzed geographical patterns of genetic variation at seven microsatellite loci among 22 populations of lake cisco located along the axis of an area covered by proglacial lakes 12,000±8000 years ago in North America. The results clearly con®rmed the existence of two genetically distinct races characterized by different sets of microsatellite alleles whose frequencies varied clinally across some 3000 km. Equilibrium and nonequilibrium analyses of isolation by distance revealed historical signal of gene ¯ow resulting from the nearly complete admixture of these races following neutral secondary contacts in their historical habitat and indicated that the colonization process occurred by a stepwise expansion of an eastern (Atlantic) race into a previously established Mississippian race.

Race is a biological grouping within human species distinguished or classified according to genetically transmitted differences. Anthropologists define race as a principal division of mankind, marked by physical characteristics that breed. According to Vidal de la Blache: “A race is great divisions of mankind, the members of which though individually vary, are characterized as a group by certain body characteristics as a group by certain body characteristics which are transmitted by nature & retained from one generation to another”. Race is a biological concept. The term race should not be used in connection with those grouping of mankind such as nation, religion, community & language which depends on feelings, ideas or habits of people and can be changes by the conscious wishes of the individual.
