Anthropological theories: evolutionism to structuralism

Anthropology (BA / B.Sc) · Social and cultural anthropology · free study notes for exams, placements and interviews

In short

Anthropological theory is the sequence of frameworks anthropologists have used to explain why human societies differ and what holds each one together — from nineteenth-century unilinear evolutionism, through diffusionism, historical particularism, functionalism and structural functionalism, to French structuralism and its neo-evolutionist and materialist rivals. It matters because every ethnographic description carries a theory inside it: what Morgan saw as a "survival", Malinowski read as a working institution and Lévi-Strauss as a sign in a system. It is the backbone paper of BA/B.Sc Anthropology under UGC CBCS (usually "History of Anthropological Thought" plus "Social and Cultural Anthropology"), and Paper I Section A of the UPSC Anthropology optional, where 15-20 marks regularly come from one theorist or one comparison. In employment terms it underlies the interpretive skills used in development consultancy, CSR and social-impact assessment, market and UX research, museum and heritage work, and the social-science research cells of bodies such as the AnSI, ICSSR institutes, NCERT and TRIs.

Explained

Classical evolutionism (c. 1860-1890): the comparative method

Diffusionism and historical particularism (c. 1890-1940): reaction against evolution

Functionalism and structural functionalism (c. 1920-1960)

Structuralism (c. 1945-1980): culture as a system of relations

Neo-evolutionism, cultural materialism and the Indian reception

Comparing the schools: what each asks and answers

Key points

Examples

Theory is not a numerical subject, so the standard exam task is to *apply* a framework to a case. Each case below is worked through to a stated conclusion, as answers are expected to be.

Case 1 — One custom, five theories: the Hindu sacred cow

  1. *Classical evolutionism (Tylor/Frazer):* a survival of an earlier animistic or totemic stage, retained after its original belief has lapsed. Weakness: it is fully alive, not a fossil.
  2. *Diffusionism:* cattle veneration spread with pastoral Indo-Aryan movement from a Central Asian centre; evidence would be trait distribution and chronology (Graebner's form and quantity criteria).
  3. *Functionalism (Malinowski):* satisfies derived needs — draught power for ploughing, dung for fuel and manure, milk — plus the integrative need for a sacred charter.
  4. *Structuralism (Lévi-Strauss/Dumont):* the cow is a term in a classification — pure/impure, vegetarian/non-vegetarian, Brahmin/untouchable — and its sanctity is positional, not intrinsic.
  5. *Cultural materialism (Harris):* infrastructure determines; the taboo is an adaptive rule protecting traction animals in a monsoon-dependent smallholder economy.

Conclusion: the "best" answer depends on the question asked — origin (1,2), present working (3,5), or meaning (4). An exam answer that names this difference scores above one that simply picks a side.

Case 2 — Deriving a structuralist reading of a myth (method, step by step)

  1. Collect all known versions; do not privilege the "authentic" one — a myth is the set of its variants.
  2. Break the narrative into mythemes (shortest sentences: "X kills the snake", "Y marries out of the village").
  3. Arrange mythemes in columns, each column a bundle sharing one relation (e.g. overrating vs underrating kinship).
  4. Read the oppositions: in the Oedipus corpus, overrating kinship / underrating kinship and denial of autochthonous origin / persistence of it.
  5. State the contradiction mediated — here, whether humans are born from the earth or from other humans.
  6. Test by transformation: does a neighbouring group's myth invert the same terms? If yes, the structure is confirmed.

Conclusion: the output is a relation, not a moral; this is why structuralism is criticised as unfalsifiable at step 6.

Case 3 — Restricted vs generalised exchange, counted

Conclusion: Lévi-Strauss's trade-off — generalised exchange buys greater integration at greater risk; this is why it correlates with hierarchy and with wife-givers/wife-takers ranking, as in parts of North-East India and in North Indian hypergamy.

Case 4 — Testing Morgan's unilinear sequence against Indian data

Conclusion: the two systems are *contemporaneous alternatives*, not successive stages, so the data falsify unilinearity and support Steward's multilinear position and Boas's particularism.

Case 5 — Which theory does Srinivas's "Sanskritisation" belong to?

  1. It is derived from fieldwork in Rampura and among the Coorgs — Malinowskian method (Srinivas trained under Radcliffe-Brown at Oxford).
  2. It explains mobility by reference to the working of the structure — a lower caste adopting the ritual, diet and ideology of a higher one, backed usually by the dominant caste's economic and numerical power.
  3. It is therefore structural-functional with a diachronic correction: it supplies the change that functionalism was accused of being unable to handle, without becoming either evolutionist or materialist.

Conclusion: classify it as structural functionalism extended to social change; contrast it with Dumont, who would read the same facts as movement within a fixed pure/impure opposition.
