Race operates as one of the most powerful organizing forces in modern societies, shaping health outcomes, educational opportunities, and criminal justice. Yet anthropology reveals a paradox: race profoundly affects people’s lives while having no biological validity. As The Human Story (Brewis et al.) puts it, race “is a belief system, not a scientifically valid way to understand human biological variation” (403). Understanding how something socially constructed can have real, material consequences is essential for anyone trying to understand inequality, power, and human variation.
Architecture: this page is the anthropological concept canonical for race and racism, drawn from two lectures in the Introduction to Anthropology course using The Human Story. Part 1 covers what race is and isn’t—colonial origins, pre-Darwinian typology, Darwin and eugenics, Franz Boas, W.E.B. Du Bois and Montague Cobb, the forensic puzzle, and how racism becomes biology. Part 2 covers how a racialized society reproduces itself—property taxes and school segregation, colorism, the census, policing, incarceration, and industrial abandonment. For Michel-Rolph Trouillot’s argument that racism produces race rather than the reverse, see Racism Produces Race. For whiteness as the unmarked category, white privilege, and intersectionality, see Whiteness as Unmarked Category. Race and racism are ultimately about power: who defines categories, who benefits, and how advantage becomes institutionalized—see the Power Analysis Hub.
Key Concepts: Race and Racism in Anthropology
- Race is a belief system, not a scientifically valid way to understand human biological variation (403). Humans are biologically varied, but the categories we use to group them don’t capture that variation.
- Individual racism (acts and beliefs people hold) is distinct from structural racism (402): “the system of inequality, often state-sanctioned and created historically” that institutionalizes racial categories regardless of individual attitudes.
- Before transoceanic colonialism, skin color varied clinally—gradually, with no sharp boundaries—as an adaptation to sun protection and vitamin D needs at different latitudes.
- Colonialism took clinal variation and blocked it into fixed racial categories over the last 500 years to organize labor and resources, placing some groups on top and forcing others to labor below.
- Carl Linnaeus (1753) and Johann Blumenbach (1795) built pre-Darwinian racial typologies as creationists; the word “Caucasian” comes from a Georgian skull Blumenbach judged most beautiful, tied to Garden of Eden mythology (406).
- Darwin’s principles—variation drives evolution, species have no fixed essence—should have demolished racial typology, but “survival of the fittest” was instead twisted into social Darwinism and eugenics (407).
- Franz Boas, founder of American academic anthropology, documented developmental plasticity: immigrants’ head and body form changed in one generation with no genetic mixing (411). W.E.B. Du Bois and Montague Cobb, among the first Black PhDs in the United States, produced empirical evidence against biological racial hierarchy.
- Race is a social construction, but racism becomes biology: “experiencing the effects of racism directly affects biology” (412), producing measurable disparities in maternal mortality, hypertension, and accelerated aging.
- Racialized societies persist (415) because advantage is institutionalized through schools, the census, policing, and housing—no individual needs to be racist for the system to reproduce itself.
Part 1: What Race Is and Isn’t

Race is a belief system—like believing the Sun goes around the Earth. Every day we see the Sun rise and set, moving around us. We believe the Earth orbits the Sun only because someone taught us in school. Race works the same way: it’s hard to shake because it’s so ingrained, but it is “not a scientifically valid way to understand human biological variation” (403).
Humans are biologically varied—different skin tones, heights, malaria resistance, lactose tolerance—but the categories we use to group people don’t capture this real variation. Even biological traits don’t bundle together under the headings we call race. Race doesn’t help us understand actual human biological diversity.
Individual vs. Structural Racism
Understanding that race isn’t biologically valid doesn’t eliminate structural racism. There’s a crucial difference. Individual racism is the acts and beliefs people hold about others—what most of us picture when we hear “racism.” Structural racism is something else: “the system of inequality, often state-sanctioned and created historically, that builds on the belief that people can be classified into distinctive, separate groups on the basis of ancestry or visible body characteristics and that these typologies reflect meaningful biological differences, justifying the belief that members of some groups are superior or inferior to others” (402).
Structural racism operates through institutions regardless of individual attitudes. Once advantages are institutionalized, individuals in the privileged group don’t need to be individually racist to benefit from the system. If a hospital treats you in a certain way based on stereotypes about who you are and how much pain you can tolerate, you have experienced structural racism whether or not anyone involved is actively racist.
The Colonial Origins of Racial Categories
In 1492, walking through various parts of the world, you would find clinal variation—gradual changes in skin color from north to south. You wouldn’t encounter sharp boundaries where populations suddenly changed from one “type” to another. This gradual variation developed from the need for sun protection and vitamin D absorption at different latitudes. You could walk from northern Europe toward the equator, or from west to east across Eurasia, and see continuous variation the whole way, with every population in between carrying some mix and wide individual variation within each.
People noticed and discussed human variation 500 to 600 years ago, but they didn’t group it into what we now call race. Racial categories emerged over the last 500 years during colonialism, when certain populations crossed oceans, subjugated others, and enslaved Africans to labor on American plantations. The colonial system took gradual variation and blocked it into fixed racial categories to justify the organization of labor and resources—some people on top, others forced to labor below. Because our categories were built from this colonial encounter, they remain a poor sample of the rest of the world: people from Papua New Guinea or the enormous range of South Asia don’t fit the early so-called science of race.
Early Scientific Racism: Pre-Darwinian Typologies
Carl Linnaeus (1753) created the kingdom-phylum-genus-species classification (and placed humans among the primates). He also sorted human “types” by skin color and temperament, describing different groups as lazy, serious, or irascible (406). He was building a typology—fixing a trait like laziness onto an entire group—combined with essentialism, the idea that species have unchanging core essences. Linnaeus was a creationist who believed he was categorizing God’s creation.
Johann Blumenbach (1795) gave us the word “Caucasian” in a five-category scheme. Like Linnaeus, he was a creationist dealing in pre-evolutionary ideas. He believed God created perfect people, and that other races “degenerated” from the most beautiful—Caucasians. The term comes from a Georgian woman’s skull he considered most beautiful, linked to the Caucasus Mountains, which he believed was the location of the Garden of Eden and Noah’s Ark. Both Linnaeus and Blumenbach produced European categories imposed on the rest of the world, based on religious belief rather than empirical evidence. Medieval Christians had already combined divine creation with typology to produce the Great Chain of Being, ranking all creatures by proximity to the divine.
How Darwin Should Have Destroyed Race (But Eugenics Emerged Instead)
Darwin introduced a radically different, scientific way of thinking about species. Natural selection depends on population diversity—you can’t have evolution without variation. Everything is always changing; species don’t have fixed essences. There is no unchanging core; the idea of essential characteristics is impossible. Properly applied, Darwinian thinking should have demolished racial typology and essentialism, because people are always changing and variable within any category. Shovel-shaped incisors illustrate the point: they vary genetically and cluster by region (large percentages in Central, Southeast, and East Asian and Melanesian populations), but there’s no population where everyone has them and can be grouped off separately. Like lactose tolerance, malaria resistance, height, and skin color, such traits come as a percentage of a population that is always changing—measurable, but never an essentialist typology.
Social Darwinism & Eugenics Instead
That’s not what happened. Instead, Darwin’s ideas were twisted into social Darwinism and eugenics (407). Darwin had preferred “descent with modification,” but he borrowed Herbert Spencer’s phrase “survival of the fittest.” That phrase fed the idea you could “breed out” less fit traits—ensuring “criminals” didn’t reproduce—which contradicts actual evolution, since evolution requires population variation. The same logic justified anti-immigration laws backed by racist science claiming that race mixing caused declining intelligence and crime—rhetoric that still echoes today in claims that certain people are “genetically bad.”
This pseudoscience was called “scientific racism,” but it wasn’t scientific—it wasn’t based on hypothesis testing, just beliefs imposed on the world. First developed in the United States and United Kingdom, it led to forced sterilization, anti-immigration laws, and the preservation of the “White race.” Hitler admired American race science and wanted to implement it in Germany, taking it even further. Some early physical anthropologists promoted eugenics, seeing it as progressive improvement of humanity.
Boas, Du Bois, and Cobb: Anthropologists Who Fought Race Science
Franz Boas, founder of American academic anthropology, was a Jewish immigrant from Germany fleeing anti-Semitism. At Ellis Island he studied Eastern European Jews and Italians, measuring their heads and comparing them over time in New York City. His discovery: even when immigrants married only within their own group (no genetic mixing), their children’s head form and body shape changed in one generation (411). This developmental plasticity—physical change based on environment without genetic change—undercut the idea that racial essences were fixed. It was radical then, and people still resist it because it dismantles fixed racial categories. There is no essential human skull.
Boas was not alone. W.E.B. Du Bois and Montague Cobb, among the first Black or African American PhDs in the United States, fought scientific racism with empirical evidence against the claim that one race was biologically inferior or superior to another. Their work helped establish what is now a common statement: race is a social construction—an idea we hold about how people group in the world, which does not describe our actual biological variation well.
Race as Social Construction: What It Means & What It Doesn’t
Anthropology eventually developed the concept that race is a social construction—a belief system we impose on real human variation. To be precise: racial categories as currently constructed don’t map onto meaningful biological variation. The categories themselves are not valid biological groupings, even though human biological variation is real. For Michel-Rolph Trouillot’s sharper formulation—that racism produces race rather than the reverse—see Racism Produces Race.
The Forensic Anthropology Puzzle
If race is socially constructed, why can forensic anthropologists identify “race” from bones? The forensic anthropologist Norman Sauer framed the question directly: “If races don’t exist, why are forensic anthropologists so good at identifying them?” (427) The answer reveals how context shapes racial classification.
The Iowa Creek Bones Example
- Bones found in an Iowa creek were analyzed against a world database; the closest match was Easter Islander.
- How many Easter Islanders in Iowa? Almost none—the world-database match alone is misleading.
- Recalculated against Iowa’s demographics (roughly 90% White), the bones come out as highly probably White.
- The same bones found in Gary, Indiana (predominantly Black) would be classified Black; found in Hawaii, Native Pacific Islander.
Forensic anthropologists give probability estimates based on geographical ancestry and local context, not fixed racial identity. They cannot tell skin color, eye shape, or ethnic markers from bones—only an estimate of ancestry mapped onto today’s racial categories. The same bones yield at least three different racial classifications depending on where they’re found.
When Race Becomes Biology: Health Disparities & Embodied Racism
Even though race isn’t biologically real, “experiencing the effects of racism directly affects biology” (412). In US hospitals, Black women are roughly three times more likely to die during childbirth, their babies about 50% more likely to be born premature and more than twice as likely to die in the first year (412). These statistics are depressing, but they’re not biological givens: some US counties achieve very different outcomes through systemic change, which proves the disparities are socially produced rather than genetic. One driver is the false assumption—held even by medical professionals—that Black patients better tolerate pain, leading to underdiagnosed pain and undertreated conditions such as sickle cell trait.
Over a lifetime, experiencing racism also produces embodied stress (414): increased hypertension, poorer sleep quality, telomere shortening, and accelerated aging. None of this is genetically transmitted—these are biological effects of living in a society with racial differentials in how people are treated. Race may not be biologically real, but its effects are.
Part 2: How a Racialized Society Reproduces Itself
Course Navigation for Intro to Anthro
← Previous: Death | Next: Extractivism →
Race is not biologically valid, yet racialized societies persist (415). Many of the structures we live inside were built decades or centuries ago, and even though we know biologically that race shouldn’t exist, the effects are deeply embedded in our social fabric. Saying “I don’t see color” doesn’t change them. Racism functions as an ideology—a set of beliefs and practices attached to a group—and racialization is how we learn from an early age to sort people into categories and then institutionalize advantages so the system perpetuates itself. Once those advantages are institutionalized, no one needs to be individually racist to benefit.
Property Taxes and School Segregation
Schools in the United States are largely funded by property taxes, which depend on home values—the single largest purchase most families make. Neighborhoods are stratified by wealth, and wealth is stratified by race: on average, the average White household holds something in the range of six to twelve times the wealth of a comparable Black household. School quality tracks wealth, and wealth tracks racial categorization. No one has to call anyone names or hold bad attitudes; wanting your children in the best school you can afford quietly reproduces a system in which some groups have far better educational opportunities than others. Brown v. Board of Education legally desegregated US schools in 1954, yet schools today are about as segregated by percentage as they were 60 or 70 years ago—driven by wealth allocation, property taxes, and the rise of private schools after legal desegregation.
Colorism: The Color Continuum
Racialization often operates through colorism (416)—valuing those closer to Whiteness, whether in skin tone, features, or general proximity to the dominant group. It’s a multi-billion-dollar global industry: skin-lightening products are sold across the Philippines, other Asian countries, and Latin America, sometimes with dangerous mercury content (the Philippines’ “Miss Poison Mercury” campaign warned against exactly this). Colorism also operates within marginalized communities—Black, Latina, and Latinx—not only between racial groups, and it surfaces in unexpected places: Cuba’s revolution promised equality, yet light-skinned leaders dominated and anti-Blackness persists, carrying into Cuban migrant communities. White Americans practice colorism too, often without realizing it: studies show people impose harsher sentences on darker-skinned than lighter-skinned Black defendants for the same crime, even though both would be classified as Black. The disparities along this color continuum can be comparable to or even exceed disparities between Black and White people overall.
Learning to Racialize: Census, Policing, Incarceration
We learn racial categorization through institutions (417–424). The census (417–418) requires everyone in the United States to answer the race question; in the census’s own terms, Hispanic, Latino, or Spanish origin is treated as an either-or rather than a race, which collides with how many people understand their own identity. Until the year 2000, respondents could check only one box—and often the census taker, not the respondent, decided. People are always mixing, and the categories can’t capture them. Policing (419–421) carries this forward: the US police system originated partly in catching escaped enslaved people, and sundown towns barred Black people from city limits after dark. Differential rates of stops, sentencing, and imprisonment persist statistically today, in a country with one of the highest incarceration rates in the industrialized world. Prisons function as an industry; voting rights are stripped, post-release employment is difficult, and many are incarcerated for offenses that arguably shouldn’t warrant prison—which is why the abolition movement asks whether the prison system itself needs rethinking.
Microaggressions and Mock Spanish
Everyday interactions (422–423) reinforce the system through small comments sometimes called microaggressions. Linguists call one form “mock Spanish”—phrases like “el cheapo” that aren’t Spanish at all but rely on stereotypes that Mexican Americans and Latinos are cheap or crazy. Speakers often want to seem easygoing and cool while reinforcing racialized stereotypes through language. These small actions, in schools, on the streets, and at home, communicate who belongs and who doesn’t.
White Supremacy
These practices reinforce what anthropology now calls white supremacy (408): “a political, economic, and cultural system in which those who are identified as ‘White’ overwhelmingly control power and material resources.” This doesn’t mean there are no wealthy or powerful people of color, or that all White people are rich—but statistically, most power and resources remain within the White population. The textbook adds that “conscious and unconscious ideas of White superiority are widespread,” that “racism is daily reenacted,” and that “systematic oppression of non-White people is justified” (408).
Ten years ago, anthropology textbooks generally did not use the term “white supremacy”—it would have been seen as too radical. With the events of 2020, including the murder of George Floyd, anthropologists became more willing to use this analytical term, and it appears in The Human Story. Today, teaching these concepts faces renewed restrictions in many states.
From Gary, Indiana to the Sugar Plantations: Extraction and Abandonment
The Iowa-and-Gary forensic example carries a deeper history. Gary, Indiana was founded by US Steel in 1906 and named for chairman Elbert H. Gary; it produced much of the steel that built American cars, bridges, and factories. With the collapse of US steel production, Gary was left impoverished and environmentally toxic—a pattern that repeats globally: extract, exploit, abandon. People go where there is silver, or steel, or sugar, bring in labor that is often coerced, take the wealth, and leave the place in ruins. Roughly four million enslaved Africans were brought to Brazilian sugar plantations, where the average working lifespan was about seven years, fueling a world economy of sugar-sweetened beverages. This bridge from racialization to colonial extraction continues on the next page: Colonial Extractivism.
Frequently Asked Questions
Is race biological?
No. Race is “a belief system, not a scientifically valid way to understand human biological variation” (403). Humans are genuinely biologically varied, but those variations are clinal and don’t bundle into the categories we call race. At the same time, racism becomes biology: “experiencing the effects of racism directly affects biology” (412), producing real disparities in health and lifespan. Both halves are true—race is not a valid biological category, and racism produces measurable biological effects.
Where do racial categories come from?
From the last 500 years of colonialism. Before transoceanic voyages, skin color varied clinally with no sharp boundaries. Colonial powers blocked that gradual variation into fixed racial categories to organize labor and resources, especially on American plantations. Pre-Darwinian creationists like Linnaeus (1753) and Blumenbach (1795) then hardened those categories into typologies, imposing European classifications on the rest of the world (406).
If races don’t exist, why can forensic anthropologists identify them?
Forensic anthropologists estimate geographical ancestry, not fixed racial identity, and the result depends on local context (427). The same Iowa creek bones read as White in Iowa, Black in Gary, Indiana, or Pacific Islander in Hawaii, because the estimate is mapped onto local demographics. Bones reveal an ancestry probability—not skin color, eye shape, or ethnic markers.
What is the difference between individual and structural racism?
Individual racism is the prejudiced acts and beliefs people hold. Structural racism is “the system of inequality, often state-sanctioned and created historically” (402) that institutionalizes racial categories through schools, housing, the census, and policing. Once advantage is institutionalized, the system reproduces itself regardless of individual attitudes—no one needs to be individually racist to benefit.
Why doesn’t educating people about race end racism?
Because structural racism operates independently of individual belief. Knowing race isn’t biologically valid doesn’t change how property taxes fund schools or how housing wealth accumulates. Michel-Rolph Trouillot argues that racism produces race rather than the reverse, which suggests education alone cannot dismantle institutional racism—developed further in Racism Produces Race.
