What is Anthropology?

Key Concepts

• Anthropology’s scope: the study of what it means to be human “in the broadest possible sense,” across all places and times (The Human Story, 3, 18).
• The founding question: “How do you know other humans when you see them?” Anthropology emerged among Europeans and North Americans reluctant to count other peoples as fully human, and insists all people in all times and places are equally part of the human family.
• Humans are hominins: bipedal, upright-walking primates sharing a most recent common ancestor with chimpanzees, gorillas, and bonobos roughly 6–8 million years ago. Homo sapiens is the sole survivor; Lucy (~3.2 million years ago), Homo erectus, Neandertals, and Denisovans are gone. Today any bipedal primate you meet is human—but that is a recent condition.
• We are primates: we did not evolve from primates—we are primates, classified among them by Linnaeus. Variation across populations is also what makes evolution possible at all.
• The four fields: biological anthropology, archaeology, cultural anthropology, and linguistic anthropology—the four subfields Franz Boas established as the North American approach, all bearing on one question: what does it mean to be human?
• Culture is learned: norms and symbols—a wedding ring, the numeral “7”—feel natural but are entirely learned, and cultures are dynamic and ever-changing rather than fixed boxes that lock people in.
• Ethnocentrism vs. cultural relativism: ethnocentrism treats one’s own culture as the natural or god-given way; cultural relativism is the intellectual commitment to understand a practice in its own context before judging—not moral relativism.
• The paradox: the very things that unite us—food, language, kinship, death rituals—are exactly what we most use to mark others as different, sometimes even as less than human.

Core Concepts & Contemporary Relevance

How Do You Know Other Humans When You See Them?

This question sits at the heart of anthropology. In our divided world, the things that make us most human—food, language, rituals, kinship—are exactly what we use to mark others as different, sometimes even to exclude them from humanity itself. Anthropology emerged to challenge this dangerous tendency, insisting that all people in all times and places are equally part of the human family.

The Scope: “All Places and Times”

Anthropology is the study of what it means to be human in the broadest possible sense. This ambitious scope emerges from a specific historical context: European and North American scholars who were reluctant to consider other peoples fully human. What might have been called straight-up racism, anthropology confronts directly by expanding our very definition of humanity.

This expansion goes deep into time. When we talk about humans, we’re part of a group called hominins—upright walking primates whose lineage stretches back 6-8 million years to our divergence from other great apes. From Lucy (3-4 million years ago) through Homo erectus, Neanderthals, Denisovans, and others, we are the sole surviving species of a once-diverse family. Today you can be confident any bipedal primate you encounter is human–but that’s a recent condition. For most of the past several million years, multiple bipedal primate species coexisted. Variation across populations is also what makes evolution possible at all: without diversity in a population, there’s nothing for natural selection to work with. We didn’t evolve from primates; we ARE primates—the last of the upright walking ones. (See the bipedalism lecture.)

The Four Fields: Different Lenses, Same Question

Because studying all humans in all times and places is impossibly broad, anthropologists organize into four interconnected subfields:

Biological Anthropology

Studies human evolution, biological diversity, and our primate relatives. Biological anthropologists examine everything from ancient fossils to contemporary human variation, showing us that while humans are 99.9% genetically similar, our visible diversity doesn’t organize into the racial categories we’ve invented.

Archaeology

Investigates the human past through material remains and artifacts. Archaeologists face a fundamental challenge: most of what humans create disappears. The plants take over, structures fade into the ground, organic materials decompose. Even when artifacts survive thousands of years, their meaning isn’t self-evident. A toilet rim might be interpreted as ceremonial headwear by future archaeologists—context is everything, and most context is lost.

Cultural Anthropology

The largest subfield in the US, studying how people share, change, and dispute culture within societies. Culture consists of learned norms (beliefs about what’s acceptable) and symbols (objects or gestures with assigned meanings). A wedding ring on the left hand means marriage in the US, but the same band might go on the right hand in Colombia. The numeral “7” only means seven because we learned it. These symbols become so ingrained they feel natural, but they’re all deeply learned.

Importantly, cultures are dynamic, fluid, and ever-changing—not static boxes that lock people into particular ways of life. People constantly navigate between multiple cultural contexts, modifying and reinterpreting their traditions.

Linguistic Anthropology

Examines human language in social context—the most important symbol-based system humans use. There’s no natural reason we call a dog “dog” instead of “perro” or “chien.” Languages encode meaning in ways that seem impossible if you weren’t raised with them: some change meaning based on inhaling versus exhaling.

The Method: Fieldwork & Participant Observation

What distinguishes anthropology is fieldwork—leaving academic spaces to immerse ourselves in lived experience. Cultural anthropologists practice ethnography (literally “writing about people”) through participant observation. Rather than just interviewing or surveying, anthropologists live with communities, participating in daily life to understand how symbols and practices make sense within their own contexts.

Crucially, anthropologists study WITH people, not just studying them as objects of research. This collaborative approach recognizes that the people we work with are experts in their own lives and cultures, making them partners in knowledge production rather than passive subjects.

The Paradox: Similarities That Divide Us

Here’s anthropology’s central insight: the very things that unite us as humans are what we use to categorize others as different. We all need to eat, but food becomes a marker of civilization versus barbarism. Everyone has kinship systems, but we judge others’ family structures as unnatural. All humans have sex, but we’re scandalized by different expressions of sexuality. Every society has death rituals, but others’ practices seem primitive or shocking.

This paradox manifests as ethnocentrism—believing your culture’s way is the right, natural, or god-given way. To counter this, anthropology proposes cultural relativism: not moral relativism that says everything’s acceptable, but an intellectual commitment to understand practices within their own contexts before judging them.

Why This Matters

In our polarized times, when political opponents get labeled “less than human,” when immigrants are dehumanized, when social media amplifies our tendency to see difference as threat, anthropology’s founding principle becomes revolutionary: recognizing the full humanity of all people.

Anthropology doesn’t just document human diversity—it reveals how our similarities become weapons of division. By understanding how we learn to see some behaviors as “natural” and others as “weird,” we can recognize the dangerous patterns that lead to dehumanization and work to counter them.

Ultimately, anthropology applies this knowledge to address real human problems. Whether examining issues of inequality, climate change, health disparities, or social justice, anthropologists use their understanding of human diversity and shared humanity to confront the pressing challenges facing our species.

The Invitation

Anthropology asks: Are you ready to see your own culture as just one possibility among many? Can you recognize that what feels natural to you might seem bizarre to others? Will you understand before you judge?

The test begins with looking at ourselves—perhaps starting with Body Ritual Among the Nacirema, where the familiar becomes foreign and the foreign, familiar.
