Anthropology is the systematic study of human beings, encompassing their biological origins, social relationships, cultural practices, and ways of communicating. It investigates both shared human characteristics and differences across places and historical periods. By connecting culture with biological and material evidence, anthropology draws on the social sciences, natural sciences, and humanities. Its scope extends from ancestral populations to contemporary communities and institutions. The term derives from Greek words meaning “human” and “study.” (americananthro.org)
Scope and disciplinary organization
Anthropology is distinguished by a broad, comparative perspective. Researchers examine how aspects of life that might be studied separately—economic activity, bodily development, political authority, and religious practice—interact in particular settings. A study of food, for example, can connect agricultural techniques, ceremonial meanings, access to resources, and human physiology. This approach treats human experience as simultaneously biological, social, and historical. (americananthro.org)
In the United States, anthropology commonly follows a four-field organization: cultural anthropology, biological anthropology, archaeology, and linguistic anthropology. Individual researchers usually specialize, while the framework encourages connections among their findings. British academic traditions prominently use the designation “social anthropology” for research on social relationships, institutions, and lived experience. Social and cultural anthropology overlap substantially, although their historical emphases differ. (americananthro.org)
Principal branches
Cultural anthropology examines learned practices, values, meanings, and social organization. Its subjects include kinship, religion, ritual, work, exchange, and political relationships. Researchers investigate how people understand their circumstances, how institutions organize everyday life, and how wider economic or political forces influence local experience. Cultural anthropology studies communities in industrialized societies as well as smaller-scale societies. (openstax.org)
Biological anthropology, historically also called physical anthropology, studies human biological origins and variation. Research connects human evolution, genetics, fossil evidence, and the comparative study of nonhuman primates. It also examines interactions between environments, social conditions, and human bodies. Some specialists apply skeletal analysis to the identification of human remains in forensic investigations. (openstax.org)
Archaeology investigates human activity through material remains, including tools, buildings, food residues, and burial contexts. Such evidence allows researchers to reconstruct settlement, production, exchange, and social organization before and after the development of writing. Archaeology’s attention to material culture also connects it with studies of objects and practices in more recent periods. (openstax.org)
Linguistic anthropology studies language as part of social and cultural life. It examines how communication creates meaning, organizes interaction, and expresses relationships. Unlike an exclusive focus on linguistic structure, this approach places speaking and other communicative practices within their social settings, while maintaining close connections with linguistics.

Historical development
Anthropology’s institutional development included learned societies, museums, government research organizations, and universities. Nineteenth-century scholars frequently sought general accounts of human development, sometimes arranging societies along a presumed single sequence of progress. Franz Boas challenged this unilineal approach and helped establish an influential American tradition emphasizing historical circumstances and detailed empirical investigation. His work contributed to the development of the modern anthropological culture concept. (archives.acls.org)
During the early twentieth century, sustained field research became central to social and cultural anthropology. Bronisław Malinowski helped establish intensive, long-term fieldwork as a major disciplinary practice. His Argonauts of the Western Pacific, published in 1922, examined ceremonial exchange among the Trobriand Islanders through closely observed social relationships and everyday activities. (openstax.org)
Research within former European empires supplied a substantial part of early social anthropology’s ethnographic record. Since the 1960s, the field has expanded its focus to urban communities, states, international organizations, and communication media. This expansion also encouraged greater attention to researchers’ relationships with the people whose lives they describe. (anthro.ox.ac.uk)
Methods and interpretation
A characteristic method of social and cultural anthropology is ethnography: intensive investigation of social life, and the written or other account produced from it. Participant observation combines involvement in everyday activities with systematic observation and recording. Interviews, conversations, field notes, and documentary or visual materials provide complementary evidence. Researchers often learn local languages and spend extended periods developing relationships with participants. (americananthro.pressbooks.pub)
Cultural relativism is a methodological commitment to understanding practices through their cultural context rather than immediately judging them by the researcher’s own assumptions. It helps counter ethnocentrism, the tendency to treat one’s own cultural standards as universally applicable. Anthropologists also compare accounts, behavior, and different forms of evidence rather than assuming that any single viewpoint fully represents a community. (explorations.americananthro.org)
Methods vary across branches. Biological anthropology uses fossil and genetic evidence, while archaeology employs excavation and analysis of artifacts and their contexts. Cultural research can combine qualitative inquiry with quantitative analysis. A survey of anthropological research practices published in 2024 documented both a common ethnographic core and considerable methodological diversity. (openstax.org)
Applications and research ethics
Applied anthropology uses anthropological research in practical settings, including technology development, urban planning, historic preservation, communications, and forensic investigation. These activities may involve universities, public institutions, businesses, or community organizations. (americananthro.org)
Professional ethics address responsibilities to participants, collaborators, affected communities, animals, and research materials. The American Anthropological Association’s principles emphasize avoiding harm, openness about research, informed consent, accessible results, and preservation of records. Consent is understood as an ongoing dialogue rather than merely a signed document. Ethical obligations can justify discontinuing research, while archaeological work carries responsibilities for conserving an irreplaceable material record. (americananthro.org)
