". Such racial identities reflect the cultural attitudes of imperial powers dominant during the age of European colonial expansion. This view rejects the notion that race is biologically defined. According to geneticist David Reich, "while race may be a social construct, differences in genetic ancestry that happen to correlate to many of today's racial constructs are real." In response to Reich, a group of 67 scientists from a broad range of disciplines wrote that his concept of race was "flawed" as "the ''meaning and significance'' of the groups is produced through social interventions". Although commonalities in physical traits such as facial features, skin color, and hair texture comprise part of the race concept, this linkage is a social distinction rather than an inherently biological one. Other dimensions of racial groupings include shared history, traditions, and language. For instance, African-American English is a language spoken by many

Historical origins of racial classification

Groups of humans have always identified themselves as distinct from neighboring groups, but such differences have not always been understood to be natural, immutable and global. These features are the distinguishing features of how the concept of race is used today. In this way the idea of race as we understand it today came about during the historical process of exploration and conquest which brought Europeans into contact with groups from different continents, and of the ideology of classification and typology found in the natural sciences. The term ''race'' was often used in a general biological taxonomic sense, starting from the 19th century, to denote genetically differentiated human

s defined by phenotype. The modern concept of race emerged as a product of the colonial enterprises of European powers from the 16th to 18th centuries which identified race in terms of skin color and physical differences. Author Rebecca F. Kennedy argues that the Greeks and Romans would have found such concepts confusing in relation to their own systems of classification. According to Bancel et al., the epistemological moment where the modern concept of race was invented and rationalized lies somewhere between 1730 and 1790.

suggested that human populations that have long inhabited separated parts of the world should, in general, be considered different subspecies by the criterion that most individuals of such populations can be allocated correctly by inspection. Wright argued that, "It does not require a trained anthropologist to classify an array of Englishmen, West Africans, and Chinese with 100% accuracy by features, skin color, and type of hair despite so much variability within each of these groups that every individual can easily be distinguished from every other." While in practice subspecies are often defined by easily observable physical appearance, there is not necessarily any evolutionary significance to these observed differences, so this form of classification has become less acceptable to evolutionary biologists. Likewise this typological approach to race is generally regarded as discredited by biologists and anthropologists.


Ancestrally differentiated populations (clades)

might be used to categorize human races biologically, and that races can be both biologically real and socially constructed. Andreasen cited tree diagrams of relative genetic distances among populations published by Luigi Cavalli-Sforza as the basis for a phylogenetic tree of human races (p. 661). Biological anthropologist Jonathan Marks (2008) responded by arguing that Andreasen had misinterpreted the genetic literature: "These trees are phenetic (based on similarity), rather than cladistic (based on

descent, that is from a series of unique ancestors)." Evolutionary biologist Alan Templeton (2013) argued that multiple lines of evidence falsify the idea of a phylogenetic tree structure to human genetic diversity, and confirm the presence of gene flow among populations. Marks, Templeton, and Cavalli-Sforza all conclude that genetics does not provide evidence of human races. Previously, anthropologists Lieberman and Jackson (1995) had also critiqued the use of cladistics to support concepts of race. They argued that "the molecular and biochemical proponents of this model explicitly use racial categories ''in their initial grouping of samples''". For example, the large and highly diverse macroethnic groups of East Indians, North Africans, and Europeans are presumptively grouped as Caucasians prior to the analysis of their DNA variation. They argued that this ''a priori'' grouping limits and skews interpretations, obscures other lineage relationships, deemphasizes the impact of more immediate clinal environmental factors on genomic diversity, and can cloud our understanding of the true patterns of affinity. In 2015, Keith Hunley, Graciela Cabana, and Jeffrey Long analyzed the Human Genome Diversity Project sample of 1,037 individuals in 52 populations, finding that diversity among non-African populations is the result of a serial founder effect process, with non-African populations as a whole nested among African populations, that "some African populations are equally related to other African populations and to non-African populations," and that "outside of Africa, regional groupings of populations are nested inside one another, and many of them are not monophyletic." Earlier research had also suggested that there has always been considerable gene flow between human populations, meaning that human population groups are not monophyletic. Rachel Caspari has argued that, since no groups currently regarded as races are monophyletic, by definition none of these groups can be clades.


Clines

One crucial innovation in reconceptualizing genotypic and phenotypic variation was the anthropologist C. Loring Brace's observation that such variations, insofar as it is affected by
natural selection Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Cha ...

, are distributed along geographic gradations or clines. For example, with respect to skin color in Europe and Africa, Brace writes:
To this day, skin color grades by imperceptible means from Europe southward around the eastern end of the Mediterranean and up the Nile into Africa. From one end of this range to the other, there is no hint of a skin color boundary, and yet the spectrum runs from the lightest in the world at the northern edge to as dark as it is possible for humans to be at the equator.
In part this is due to
isolation by distance Isolation by distance (IBD) is a term used to refer to the accrual of local genetic variation under geographically limited dispersal. The IBD model is useful for determining the distribution of gene frequencies over a geographic region. Both disp ...
. This point called attention to a problem common to phenotype-based descriptions of races (for example, those based on hair texture and skin color): they ignore a host of other similarities and differences (for example, blood type) that do not correlate highly with the markers for race. Thus, anthropologist Frank Livingstone's conclusion, that since clines cross racial boundaries, "there are no races, only clines". In a response to Livingstone,
Theodore Dobzhansky Theodosius Grigorievich Dobzhansky (russian: Феодо́сий Григо́рьевич Добржа́нский; uk, Теодо́сій Григо́рович Добржа́нський; January 25, 1900 – December 18, 1975) was a prominent ...
argued that when talking about race one must be attentive to how the term is being used: "I agree with Dr. Livingstone that if races have to be 'discrete units', then there are no races, and if 'race' is used as an 'explanation' of the human variability, rather than vice versa, then the explanation is invalid." He further argued that one could use the term race if one distinguished between "race differences" and "the race concept". The former refers to any distinction in gene frequencies between populations; the latter is "a matter of judgment". He further observed that even when there is clinal variation, "Race differences are objectively ascertainable biological phenomena ... but it does not follow that racially distinct populations must be given racial (or subspecific) labels." In short, Livingstone and Dobzhansky agree that there are genetic differences among human beings; they also agree that the use of the race concept to classify people, and how the race concept is used, is a matter of social convention. They differ on whether the race concept remains a meaningful and useful social convention. In 1964, the biologists Paul Ehrlich and Holm pointed out cases where two or more clines are distributed discordantly – for example, melanin is distributed in a decreasing pattern from the equator north and south; frequencies for the haplotype for beta-S hemoglobin, on the other hand, radiate out of specific geographical points in Africa. As the anthropologists Leonard Lieberman and Fatimah Linda Jackson observed, "Discordant patterns of heterogeneity falsify any description of a population as if it were genotypically or even phenotypically homogeneous". Patterns such as those seen in human physical and genetic variation as described above, have led to the consequence that the number and geographic location of any described races is highly dependent on the importance attributed to, and quantity of, the traits considered. A skin-lightening mutation, estimated to have occurred 20,000 to 50,000 years ago, partially accounts for the appearance of light skin in people who migrated out of Africa northward into what is now Europe. East Asians owe their relatively light skin to different mutations. On the other hand, the greater the number of traits (or

s) considered, the more subdivisions of humanity are detected, since traits and gene frequencies do not always correspond to the same geographical location. Or as put it:


Genetically differentiated populations

Another way to look at differences between populations is to measure genetic differences rather than physical differences between groups. The mid-20th-century anthropologist
William C. Boyd William Clouser Boyd (March 4, 1903 – February 19, 1983) was an American immunochemist. In the 1930s, with his wife Lyle, he made a worldwide survey of the distribution of blood types. Biography Born in Dearborn, Missouri, Boyd was educat ...
defined race as: "A population which differs significantly from other populations in regard to the frequency of one or more of the genes it possesses. It is an arbitrary matter which, and how many, gene loci we choose to consider as a significant 'constellation'". Leonard Lieberman and Rodney Kirk have pointed out that "the paramount weakness of this statement is that if one gene can distinguish races then the number of races is as numerous as the number of human couples reproducing." Moreover, the anthropologist Stephen Molnar has suggested that the discordance of clines inevitably results in a multiplication of races that renders the concept itself useless. The

states "People who have lived in the same geographic region for many generations may have some alleles in common, but no allele will be found in all members of one population and in no members of any other." Massimo Pigliucci and Jonathan Kaplan argue that human races do exist, and that they correspond to the genetic classification of

s, but that real human races do not correspond very much, if at all, to folk racial categories. In contrast, Walsh & Yun reviewed the literature in 2011 and reported that "Genetic studies using very few chromosomal loci find that genetic polymorphisms divide human populations into clusters with almost 100 percent accuracy and that they correspond to the traditional anthropological categories." Some biologists argue that racial categories correlate with biological traits (e.g.

), and that certain genetic markers have varying frequencies among human populations, some of which correspond more or less to traditional racial groupings.


= Distribution of genetic variation

= The distribution of genetic variants within and among human populations are impossible to describe succinctly because of the difficulty of defining a population, the clinal nature of variation, and heterogeneity across the genome (Long and Kittles 2003). In general, however, an average of 85% of statistical genetic variation exists within local populations, ≈7% is between local populations within the same continent, and ≈8% of variation occurs between large groups living on different continents. The recent African origin theory for humans would predict that in Africa there exists a great deal more diversity than elsewhere and that diversity should decrease the further from Africa a population is sampled. Hence, the 85% average figure is misleading: Long and Kittles find that rather than 85% of human genetic diversity existing in all human populations, about 100% of human diversity exists in a single African population, whereas only about 60% of human genetic diversity exists in the least diverse population they analyzed (the Surui, a population derived from New Guinea). Statistical analysis that takes this difference into account confirms previous findings that, "Western-based racial classifications have no taxonomic significance."


= Cluster analysis

= A 2002 study of random biallelic genetic loci found little to no evidence that humans were divided into distinct biological groups. In his 2003 paper, " Human Genetic Diversity: Lewontin's Fallacy", A. W. F. Edwards argued that rather than using a locus-by-locus analysis of variation to derive taxonomy, it is possible to construct a human classification system based on characteristic genetic patterns, or ''clusters'' inferred from multilocus genetic data. Geographically based human studies since have shown that such genetic clusters can be derived from analyzing of a large number of loci which can assort individuals sampled into groups analogous to traditional continental racial groups.

cautioned that while genetic clusters may one day be shown to correspond to phenotypic variations between groups, such assumptions were premature as the relationship between genes and

remains poorly understood. However, Risch denied such limitations render the analysis useless: "Perhaps just using someone's actual birth year is not a very good way of measuring age. Does that mean we should throw it out? ... Any category you come up with is going to be imperfect, but that doesn't preclude you from using it or the fact that it has utility." Early human genetic cluster analysis studies were conducted with samples taken from ancestral population groups living at extreme geographic distances from each other. It was thought that such large geographic distances would maximize the genetic variation between the groups sampled in the analysis, and thus maximize the probability of finding cluster patterns unique to each group. In light of the historically recent acceleration of human migration (and correspondingly, human gene flow) on a global scale, further studies were conducted to judge the degree to which genetic cluster analysis can pattern ancestrally identified groups as well as geographically separated groups. One such study looked at a large multiethnic population in the United States, and "detected only modest genetic differentiation between different current geographic locales within each race/ethnicity group. Thus, ancient geographic ancestry, which is highly correlated with self-identified race/ethnicity – as opposed to current residence – is the major determinant of genetic structure in the U.S. population." have argued that even when individuals can be reliably assigned to specific population groups, it may still be possible for two randomly chosen individuals from different populations/clusters to be more similar to each other than to a randomly chosen member of their own cluster. They found that many thousands of genetic markers had to be used in order for the answer to the question "How often is a pair of individuals from one population genetically more dissimilar than two individuals chosen from two different populations?" to be "never". This assumed three population groups separated by large geographic ranges (European, African and East Asian). The entire world population is much more complex and studying an increasing number of groups would require an increasing number of markers for the same answer. The authors conclude that "caution should be used when using geographic or genetic ancestry to make inferences about individual phenotypes." Witherspoon, et al. concluded that, "The fact that, given enough genetic data, individuals can be correctly assigned to their populations of origin is compatible with the observation that most human genetic variation is found within populations, not between them. It is also compatible with our finding that, even when the most distinct populations are considered and hundreds of loci are used, individuals are frequently more similar to members of other populations than to members of their own population." Anthropologists such as C. Loring Brace, the philosophers Jonathan Kaplan and Rasmus Winther, and the geneticist Joseph Graves, have argued that while there it is certainly possible to find biological and genetic variation that corresponds roughly to the groupings normally defined as "continental races", this is true for almost all geographically distinct populations. The cluster structure of the genetic data is therefore dependent on the initial hypotheses of the researcher and the populations sampled. When one samples continental groups, the clusters become continental; if one had chosen other sampling patterns, the clustering would be different. Weiss and Fullerton have noted that if one sampled only Icelanders, Mayans and Maoris, three distinct clusters would form and all other populations could be described as being clinally composed of admixtures of Maori, Icelandic and Mayan genetic materials. Kaplan and Winther therefore argue that, seen in this way, both Lewontin and Edwards are right in their arguments. They conclude that while racial groups are characterized by different allele frequencies, this does not mean that racial classification is a natural taxonomy of the human species, because multiple other genetic patterns can be found in human populations that crosscut racial distinctions. Moreover, the genomic data underdetermines whether one wishes to see subdivisions (i.e., splitters) or a continuum (i.e., lumpers). Under Kaplan and Winther's view, racial groupings are objective social constructions (see Mills 1998) that have conventional biological reality only insofar as the categories are chosen and constructed for pragmatic scientific reasons. In earlier work, Winther had identified "diversity partitioning" and "clustering analysis" as two separate methodologies, with distinct questions, assumptions, and protocols. Each is also associated with opposing ontological consequences vis-a-vis the metaphysics of race. Philosopher Lisa Gannett has argued that

= Clines and clusters in genetic variation

= Recent studies of human genetic clustering have included a debate over how genetic variation is organized, with clusters and clines as the main possible orderings. argued for smooth, clinal genetic variation in ancestral populations even in regions previously considered racially homogeneous, with the apparent gaps turning out to be artifacts of sampling techniques. disputed this and offered an analysis of the Human Genetic Diversity Panel showing that there were small discontinuities in the smooth genetic variation for ancestral populations at the location of geographic barriers such as the

. Nonetheless, stated that their findings "should not be taken as evidence of our support of any particular concept of biological race... Genetic differences among human populations derive mainly from gradations in allele frequencies rather than from distinctive 'diagnostic' genotypes." Using a sample of 40 populations distributed roughly evenly across the Earth's land surface, found that "genetic diversity is distributed in a more clinal pattern when more geographically intermediate populations are sampled." Guido Barbujani has written that human genetic variation is generally distributed continuously in gradients across much of Earth, and that there is no evidence that genetic boundaries between human populations exist as would be necessary for human races to exist. Over time, human genetic variation has formed a nested structure that is inconsistent with the concept of races that have evolved independently of one another.

Upon examining the data from the genome mapping, Venter realized that although the genetic variation within the human species is on the order of 1–3% (instead of the previously assumed 1%), the types of variations do not support notion of genetically defined races. Venter said, "Race is a social concept. It's not a scientific one. There are no bright lines (that would stand out), if we could compare all the sequenced genomes of everyone on the planet."

According to anthropologist Marvin Harris, this pattern reflects a different history and different social relations. Race in Brazil was "biologized", but in a way that recognized the difference between ancestry (which determines

differences. There, racial identity was not governed by rigid descent rule, such as the one-drop rule, as it was in the United States. A Brazilian child was never automatically identified with the racial type of one or both parents, nor were there only a very limited number of categories to choose from, to the extent that full siblings can pertain to different racial groups. Over a dozen racial categories would be recognized in conformity with all the possible combinations of hair color, hair texture, eye color, and skin color. These types grade into each other like the colors of the spectrum, and not one category stands significantly isolated from the rest. That is, race referred preferentially to appearance, not heredity, and appearance is a poor indication of ancestry, because only a few genes are responsible for someone's skin color and traits: a person who is considered white may have more African ancestry than a person who is considered black, and the reverse can be also true about European ancestry. The complexity of racial classifications in Brazil reflects the extent of genetic mixing in Brazilian society, a society that remains highly, but not strictly,

, for those of lower quantity of Amerindian descent a higher European genetic contribution is expected to be grouped as a ''pardo''. In several genetic tests, people with less than 60-65% of European descent and 5–10% of Amerindian descent usually cluster with Afro-Brazilians (as reported by the individuals), or 6.9% of the population, and those with about 45% or more of Subsaharan contribution most times do so (in average, Afro-Brazilian DNA was reported to be about 50% Subsaharan African, 37% European and 13% Amerindian). If a more consistent report with the genetic groups in the gradation of genetic mixing is to be considered (e.g. that would not cluster people with a balanced degree of African and non-African ancestry in the black group instead of the multiracial one, unlike elsewhere in Latin America where people of high quantity of African descent tend to classify themselves as mixed), more people would report themselves as white and ''pardo'' in Brazil (47.7% and 42.4% of the population as of 2010, respectively), because by research its population is believed to have between 65 and 80% of autosomal European ancestry, in average (also >35% of European mt-DNA and >95% of European Y-DNA).

until the 1950s, the proportion of the white population increased significantly while Brazil welcomed 5.5 million immigrants between 1821 and 1932, not much behind its neighbor Argentina with 6.4 million,, Cited in and it received more European immigrants in its colonial history than the United States. Between 1500 and 1760, 700.000 Europeans settled in Brazil, while 530.000 Europeans settled in the United States for the same given time. Thus, the historical construction of race in Brazilian society dealt primarily with gradations between persons of majority European ancestry and little minority groups with otherwise lower quantity therefrom in recent times.

The concept of racial origin relies on the notion that human beings can be separated into biologically distinct "races", an idea generally rejected by the scientific community. Since all human beings belong to the same species, the ECRI (European Commission against Racism and Intolerance) rejects theories based on the existence of different "races". However, in its Recommendation ECRI uses this term in order to ensure that those persons who are generally and erroneously perceived as belonging to "another race" are not excluded from the protection provided for by the legislation. The law claims to reject the existence of "race", yet penalize situations where someone is treated less favourably on this ground.

era, increasing numbers of Americans began to consider anyone with " one drop" of known "Black blood" to be Black, regardless of appearance. By the early 20th century, this notion was made statutory in many states. Amerindians continue to be defined by a certain percentage of "Indian blood" (called '' blood quantum''). To be White one had to have perceived "pure" White ancestry. The one-drop rule or hypodescent rule refers to the convention of defining a person as racially black if he or she has any known African ancestry.

The one-drop rule is specific to not only those with African ancestry but to the United States, making it a particularly African-American experience.

Views across disciplines over time


Anthropology

The concept of race classification in physical anthropology lost credibility around the 1960s and is now considered untenable. A 2019 statement by the American Association of Physical Anthropologists declares:
Race does not provide an accurate representation of human biological variation. It was never accurate in the past, and it remains inaccurate when referencing contemporary human populations. Humans are not divided biologically into distinct continental types or racial genetic clusters. Instead, the Western concept of race must be understood as a classification system that emerged from, and in support of, European colonialism, oppression, and discrimination.
Wagner et al. (2017) surveyed 3,286 American anthropologists' views on race and genetics, including both cultural and biological anthropologists. They found a consensus among them that biological races do not exist in humans, but that race does exist insofar as the social experiences of members of different races can have significant effects on health. Wang, Štrkalj et al. (2003) examined the use of race as a biological concept in research papers published in China's only biological anthropology journal, ''Acta Anthropologica Sinica''. The study showed that the race concept was widely used among Chinese anthropologists. In a 2007 review paper, Štrkalj suggested that the stark contrast of the racial approach between the United States and China was due to the fact that race is a factor for social cohesion among the ethnically diverse people of China, whereas "race" is a very sensitive issue in America and the racial approach is considered to undermine social cohesion – with the result that in the socio-political context of US academics scientists are encouraged not to use racial categories, whereas in China they are encouraged to use them. Lieberman et al. in a 2004 study researched the acceptance of race as a concept among anthropologists in the United States, Canada, the Spanish speaking areas, Europe, Russia and China. Rejection of race ranged from high to low, with the highest rejection rate in the United States and Canada, a moderate rejection rate in Europe, and the lowest rejection rate in Russia and China. Methods used in the studies reported included questionnaires and content analysis. Kaszycka et al. (2009) in 2002–2003 surveyed European anthropologists' opinions toward the biological race concept. Three factors, country of academic education, discipline, and age, were found to be significant in differentiating the replies. Those educated in Western Europe, physical anthropologists, and middle-aged persons rejected race more frequently than those educated in Eastern Europe, people in other branches of science, and those from both younger and older generations." The survey shows that the views on race are sociopolitically (ideologically) influenced and highly dependent on education."

According to one academic journal entry, where 78 percent of the articles in the 1931 ''Journal of Physical Anthropology'' employed these or nearly synonymous terms reflecting a bio-race paradigm, only 36 percent did so in 1965, and just 28 percent did in 1996.

s: 69% * cultural anthropologists: 80% A line of research conducted by Cartmill (1998), however, seemed to limit the scope of Lieberman's finding that there was "a significant degree of change in the status of the race concept". Goran Štrkalj has argued that this may be because Lieberman and collaborators had looked at all the members of the American Anthropological Association irrespective of their field of research interest, while Cartmill had looked specifically at biological anthropologists interested in human variation. In 2007, Ann Morning interviewed over 40 American biologists and anthropologists and found significant disagreements over the nature of race, with no one viewpoint holding a majority among either group. Morning also argues that a third position, "antiessentialism", which holds that race is not a useful concept for biologists, should be introduced into this debate in addition to "constructionism" and "essentialism".

has said that the idea that race is only skin deep "is simply not true, as any experienced forensic anthropologist will affirm" and "Many morphological features 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.)" While he can see good arguments for both sides, the complete denial of the opposing evidence "seems to stem largely from socio-political motivation and not science at all". He also states that many biological anthropologists see races as real yet "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". In partial response to Gill's statement, Professor of Biological Anthropology C. Loring Brace argues that the reason laymen and biological anthropologists can determine the geographic ancestry of an individual can be explained by the fact that biological characteristics are clinally distributed across the planet, and that does not translate into the concept of race. He states: The concept of "race" is still sometimes used within forensic anthropology (when analyzing skeletal remains),

, and race-based medicine. Brace has criticized forensic anthropologists for this, arguing that they in fact should be talking about regional ancestry. He argues that while forensic anthropologists can determine that a skeletal remain comes from a person with ancestors in a specific region of Africa, categorizing that skeletal as being "black" is a socially constructed category that is only meaningful in the particular social context of the United States, and which is not itself scientifically valid.


Biology, anatomy, and medicine

s and 36% of the surveyed developmental psychologists disagreed with the proposition: "There are biological races in the species ''Homo sapiens''." The authors of the study also examined 77 college textbooks in biology and 69 in physical anthropology published between 1932 and 1989. Physical anthropology texts argued that biological races exist until the 1970s, when they began to argue that races do not exist. In contrast, biology textbooks did not undergo such a reversal but many instead dropped their discussion of race altogether. The authors attributed this to biologists trying to avoid discussing the political implications of racial classifications, and to the ongoing discussions in biology about the validity of the idea of "subspecies". The authors concluded, "The concept of race, masking the overwhelming genetic similarity of all peoples and the mosaic patterns of variation that do not correspond to racial divisions, is not only socially dysfunctional but is biologically indefensible as well (pp. 5 18–5 19)." A 1994 examination of 32 English sport/exercise science textbooks found that 7 (21.9%) claimed that there are biophysical differences due to race that might explain differences in sports performance, 24 (75%) did not mention nor refute the concept, and 1 (3.1%) expressed caution with the idea. In February 2001, the editors of '' Archives of Pediatrics and Adolescent Medicine'' asked "authors to not use race and ethnicity when there is no biological, scientific, or sociological reason for doing so." The editors also stated that "analysis by race and ethnicity has become an analytical knee-jerk reflex." ''Nature Genetics'' now ask authors to "explain why they make use of particular ethnic groups or populations, and how classification was achieved." Morning (2008) looked at high school biology textbooks during the 1952–2002 period and initially found a similar pattern with only 35% directly discussing race in the 1983–92 period from initially 92% doing so. However, this has increased somewhat after this to 43%. More indirect and brief discussions of race in the context of medical disorders have increased from none to 93% of textbooks. In general, the material on race has moved from surface traits to genetics and evolutionary history. The study argues that the textbooks' fundamental message about the existence of races has changed little. Surveying views on race in the scientific community in 2008, Morning concluded that biologists had failed to come to a clear consensus, and they often split along cultural and demographic lines. She notes, "At best, one can conclude that biologists and anthropologists now appear equally divided in their beliefs about the nature of race." Gissis (2008) examined several important American and British journals in genetics, epidemiology and medicine for their content during the 1946–2003 period. He wrote that "Based upon my findings I argue that the category of race only ''seemingly'' disappeared from scientific discourse after World War II and has had a ''fluctuating yet continuous use'' during the time span from 1946 to 2003, and has even ''become more pronounced from the early 1970s on''". 33 health services researchers from differing geographic regions were interviewed in a 2008 study. The researchers recognized the problems with racial and ethnic variables but the majority still believed these variables were necessary and useful. A 2010 examination of 18 widely used English

textbooks found that they all represented human biological variation in superficial and outdated ways, many of them making use of the race concept in ways that were current in 1950s anthropology. The authors recommended that anatomical education should describe human anatomical variation in more detail and rely on newer research that demonstrates the inadequacies of simple racial typologies. A 2021 study that examined over 11,000 papers from 1949 to 2018 in The American Journal of Human Genetics, found that "race" was used in only 5% of papers published in the last decade, down from 22% in the first. Together with an increase in use of the terms "ethnicity," "ancestry," and location-based terms, it suggests that human geneticists have mostly abandoned the term "race."


Sociology

Lester Frank Ward (1841–1913), considered to be one of the founders of American sociology, rejected notions that there were fundamental differences that distinguished one race from another, although he acknowledged that social conditions differed dramatically by race. At the turn of the 20th century, sociologists viewed the concept of race in ways that were shaped by the scientific racism of the 19th and early 20th centuries. Many sociologists focused on African Americans, called

es at that time, and claimed that they were inferior to whites. White sociologist Charlotte Perkins Gilman (1860–1935), for example, used biological arguments to claim the inferiority of African Americans. American sociologist Charles H. Cooley (1864–1929) theorized that differences among races were "natural," and that biological differences result in differences in intellectual abilities Edward Alsworth Ross (1866–1951), also an important figure in the founding of American sociology, and a

(1868–1963), one of the first African-American sociologists, was the first sociologist to use sociological concepts and empirical research methods to analyze race as a social construct instead of a biological reality. Beginning in 1899 with his book ''The Philadelphia Negro'', Du Bois studied and wrote about race and racism throughout his career. In his work, he contended that social class, colonialism, and capitalism shaped ideas about race and racial categories. Social scientists largely abandoned scientific racism and biological reasons for racial categorization schemes by the 1930s.Fitzgerald, Kathleen J. ''Recognizing Race and Ethnicity: Power, Privilege, and Inequality.'' 2014. Boulder, CO: Westview Press. Other early sociologists, especially those associated with the Chicago school (sociology), Chicago School, joined Du Bois in theorizing race as a socially constructed fact. By 1978, William Julius Wilson argued that race and racial classification systems were declining in significance, and that instead, social class more accurately described what sociologists had earlier understood as race. By 1986, sociologists Michael Omi and Howard Winant successfully introduced the concept of Racial formation theory, racial formation to describe the process by which racial categories are created. Omi and Winant assert that "there is no biological basis for distinguishing among human groups along the lines of race." Eduardo Bonilla-Silva, Sociology professor at Duke University, remarks, "I contend that racism is, more than anything else, a matter of group power; it is about a dominant racial group (whites) striving to maintain its systemic advantages and minorities fighting to subvert the racial status quo." The types of practices that take place under this new color-blind racism is subtle, institutionalized, and supposedly not racial. Color-blind racism thrives on the idea that race is no longer an issue in the United States. There are contradictions between the alleged color-blindness of most whites and the persistence of a color-coded system of inequality. Today, sociologists generally understand race and racial categories as socially constructed, and reject racial categorization schemes that depend on biological differences.


Political and practical uses


Biomedicine

In the United States, federal government policy promotes the use of racially categorized data to identify and address health disparities between racial or ethnic groups. In clinical settings, race has sometimes been considered in the diagnosis and treatment of medical conditions. Doctors have noted that some medical conditions are more prevalent in certain racial or ethnic groups than in others, without being sure of the cause of those differences. Recent interest in race-based medicine, or race-targeted pharmacogenomics, has been fueled by the proliferation of human genetic data which followed the Human Genome Project, decoding of the human genome in the first decade of the twenty-first century. There is an active debate among biomedical researchers about the meaning and importance of race in their research. Proponents of the use of racial categories in biomedicine argue that continued use of racial categorizations in biomedical research and clinical practice makes possible the application of new genetic findings, and provides a clue to diagnosis. Biomedical researchers' positions on race fall into two main camps: those who consider the concept of race to have no biological basis and those who consider it to have the potential to be biologically meaningful. Members of the latter camp often base their arguments around the potential to create genome-based personalized medicine. Other researchers point out that finding a difference in disease prevalence between two socially defined groups does not necessarily imply genetic causation of the difference. They suggest that medical practices should maintain their focus on the individual rather than an individual's membership to any group. They argue that overemphasizing genetic contributions to health disparities carries various risks such as reinforcing stereotypes, promoting racism or ignoring the contribution of non-genetic factors to health disparities. International epidemiological data show that living conditions rather than race make the biggest difference in health outcomes even for diseases that have "race-specific" treatments. Some studies have found that patients are reluctant to accept racial categorization in medical practice.


Law enforcement

In an attempt to provide general descriptions that may facilitate the job of law enforcement officers seeking to apprehend suspects, the United States Federal Bureau of Investigation, FBI employs the term "race" to summarize the general appearance (skin color, hair texture, eye shape, and other such easily noticed characteristics) of individuals whom they are attempting to apprehend. From the perspective of
law enforcement Law enforcement is the activity of some members of government who act in an organized manner to enforce the law by discovering, deterring, rehabilitating, or punishing people who violate the rules and norms governing that society. The term ...
officers, it is generally more important to arrive at a description that will readily suggest the general appearance of an individual than to make a scientifically valid categorization by DNA or other such means. Thus, in addition to assigning a wanted individual to a racial category, such a description will include: height, weight, eye color, scars and other distinguishing characteristics. Criminal justice agencies in England and Wales use at least two separate racial/ethnic classification systems when reporting crime, as of 2010. One is the system used in the United Kingdom Census 2001#Ethnicity, 2001 Census when individuals identify themselves as belonging to a particular ethnic group: W1 (White-British), W2 (White-Irish), W9 (Any other white background); M1 (White and black Caribbean), M2 (White and black African), M3 (White and Asian), M9 (Any other mixed background); A1 (Asian-Indian), A2 (Asian-Pakistani), A3 (Asian-Bangladeshi), A9 (Any other Asian background); B1 (Black Caribbean), B2 (Black African), B3 (Any other black background); O1 (Chinese), O9 (Any other). The other is categories used by the police when they visually identify someone as belonging to an ethnic group, e.g. at the time of a stop and search or an arrest: White – North European (IC1), White – South European (IC2), Black (IC3), Asian (IC4), Chinese, Japanese, or South East Asian (IC5), Middle Eastern (IC6), and Unknown (IC0). "IC" stands for "Identification Code;" these items are also referred to as Phoenix classifications. Officers are instructed to "record the response that has been given" even if the person gives an answer which may be incorrect; their own perception of the person's ethnic background is recorded separately. Comparability of the information being recorded by officers was brought into question by the Office for National Statistics (ONS) in September 2007, as part of its Equality Data Review; one problem cited was the number of reports that contained an ethnicity of "Not Stated." In many countries, such as
France France (), officially the French Republic ( ), is a country primarily located in Western Europe. It also comprises of Overseas France, overseas regions and territories in the Americas and the Atlantic Ocean, Atlantic, Pacific Ocean, Pac ...
, the state is legally banned from maintaining data based on race. In the United States, the practice of racial profiling has been ruled to be both unconstitutional and a violation of civil rights. There is active debate regarding the cause of a marked correlation between the recorded crimes, punishments meted out, and the country's populations. Many consider ''de facto'' racial profiling an example of institutional racism in law enforcement. Mass incarceration in the United States disproportionately impacts African American and Latino communities. Michelle Alexander, author of ''The New Jim Crow: Mass Incarceration in the Age of Colorblindness'' (2010), argues that mass incarceration is best understood as not only a system of overcrowded prisons. Mass incarceration is also, "the larger web of laws, rules, policies, and customs that control those labeled criminals both in and out of prison." She defines it further as "a system that locks people not only behind actual bars in actual prisons, but also behind virtual bars and virtual walls", illustrating the second-class citizenship that is imposed on a disproportionate number of people of color, specifically African-Americans. She compares mass incarceration to Jim Crow laws, stating that both work as racial caste systems. Many research findings appear to agree that the impact of victim race in the interpersonal violence (IPV) arrest decision might include a racial bias in favor of white victims. A 2011 study in a national sample of IPV arrests found that female arrest was more likely if the male victim was white and the female offender was black, while male arrest was more likely if the female victim was white. For both female and male arrest in IPV cases, situations involving married couples were more likely to lead to arrest compared to dating or divorced couples. More research is needed to understand agency and community factors that influence police behavior and how discrepancies in IPV interventions/ tools of justice can be addressed. Recent work using DNA cluster analysis to determine race background has been used by some criminal investigators to narrow their search for the identity of both suspects and victims. Proponents of DNA profiling in criminal investigations cite cases where leads based on DNA analysis proved useful, but the practice remains controversial among medical ethicists, defense lawyers and some in law enforcement. The Constitution of Australia contains a line about 'people of any race for whom it is deemed necessary to make special laws', despite there being no agreed definition of race described in the document.


Forensic anthropology

Similarly, forensic anthropologists draw on highly heritable morphological features of human remains (e.g. cranial measurements) to aid in the identification of the body, including in terms of race. In a 1992 article, anthropologist Norman Sauer noted that anthropologists had generally abandoned the concept of race as a valid representation of human biological diversity, except for forensic anthropologists. He asked, "If races don't exist, why are forensic anthropologists so good at identifying them?" He concluded: Identification of the ancestry of an individual is dependent upon knowledge of the frequency and distribution of phenotypic traits in a population. This does not necessitate the use of a racial classification scheme based on unrelated traits, although the race concept is widely used in medical and legal contexts in the United States. Some studies have reported that races can be identified with a high degree of accuracy using certain methods, such as that developed by Giles and Elliot. However, this method sometimes fails to be replicated in other times and places; for instance, when the method was re-tested to identify Native Americans, the average rate of accuracy dropped from 85% to 33%. Prior information about the individual (e.g. Census data) is also important in allowing the accurate identification of the individual's "race". In a different approach, anthropologist C. Loring Brace said: In association with a NOVA program in 2000 about race, he wrote an essay opposing use of the term. A 2002 study found that about 13% of human craniometric variation existed between regions, while 6% existed between local populations within regions and 81% within local populations. In contrast, the opposite pattern of genetic variation was observed for skin color (which is often used to define race), with 88% of variation between regions. The study concluded that "The apportionment of genetic diversity in skin color is atypical, and cannot be used for purposes of classification." Similarly, a 2009 study found that craniometrics could be used accurately to determine what part of the world someone was from based on their cranium; however, this study also found that there were no abrupt boundaries that separated craniometric variation into distinct racial groups. Another 2009 study showed that American blacks and whites had different skeletal morphologies, and that significant patterning in variation in these traits exists within continents. This suggests that classifying humans into races based on skeletal characteristics would necessitate many different "races" being defined. In 2010, philosopher Neven Sesardic argued that when several traits are analyzed at the same time, forensic anthropologists can classify a person's race with an accuracy of close to 100% based on only skeletal remains. Sesardic's claim has been disputed by philosopher Massimo Pigliucci, who accused Sesardic of "cherry pick[ing] the scientific evidence and reach[ing] conclusions that are contradicted by it." Specifically, Pigliucci argued that Sesardic misrepresented a paper by Ousley et al. (2009), and neglected to mention that they identified differentiation not just between individuals from different races, but also between individuals from different tribes, local environments, and time periods.
