Official Syllabus: Paper I, Unit 1.3

1. The Four-Field Structure

Think of one tribal community, such as the Santal of Jharkhand. A socio-cultural anthropologist studies their festivals, clans and village council. A biological anthropologist studies their growth, blood groups and genetic ancestry. An archaeologist studies the stone tools and pottery left at old settlement sites. A linguistic anthropologist studies the Santali language and how it is used. Each of these is a branch of one discipline.

• Anthropology is one discipline with four branches because humans are at once biological, social, historical and symbolic (using language and meaning). No single method can capture all four.
• The four-field model is American in origin. Franz Boas, the German-born founder of American academic anthropology, built it into teaching at Columbia University. His reasoning was practical: to understand a Native American people properly, one needed their bodies, languages, past and customs together, and all four were vanishing at the same time.
• British usage long recognised three branches: physical anthropology, social (or cultural) anthropology and archaeology, with linguistics treated as a specialist field (Colin Renfrew and Paul Bahn, British archaeologists, in Archaeology, 1991).
• Indian departments follow an integrated model: all branches are studied together and specialisation comes late. The UPSC syllabus mirrors this.
• Applied anthropology is often called the “fifth field”. It has no subject matter of its own; it uses the knowledge of all four branches to solve practical problems (§6).

The table below sets the four branches side by side. Notice that each asks a different question and works with a different kind of evidence.

Branch	Core question	Main evidence	Time depth	Typical method	Bridges to
Social-cultural	How do people live, organise and give meaning?	Observed behaviour, narratives, institutions	Present and recent past	Participant observation, comparison	Sociology, history, psychology
Biological	How did humans evolve and why do they vary?	Fossils, bodies, genes, primates	7 million years to now	Measurement, laboratory analysis	Anatomy, genetics, medicine
Archaeological	How did past people live and change?	Artefacts, ecofacts, features	3.3 million years to recent	Survey, excavation, dating	Geology, history, chemistry
Linguistic	How do language and culture shape each other?	Speech, texts, grammars	Present, reconstructed past	Recording, transcription, analysis	Linguistics, psychology, semiotics

Read the table across each row and a pattern appears. The branches differ mainly in evidence and time depth: socio-cultural and linguistic anthropologists work with living people who can be asked and observed, while archaeologists and palaeoanthropologists work with silent remains that must be interpreted. This is also why their methods differ, from conversation and observation at one end to excavation and laboratory dating at the other. Yet every row ends in the same question, what makes humans what they are, which is why the four belong to one discipline.

• Why keep the branches together? Holism: studying a group as a connected whole, because its biology, society, language and history affect one another. In West Africa, forest clearing for farming (culture) created pools where malaria mosquitoes bred (environment), which favoured the sickle-cell gene (biology); one branch alone would miss the chain (Unit 1.1 §2.1).
• How the branches cooperate in practice, and the pressures pulling them apart, are discussed in §7.

2. Social-Cultural Anthropology

2.1 Meaning and definitions

• Social-cultural anthropology is the comparative study of living human societies and cultures: their institutions (established patterns such as marriage, markets or councils), their values, and the meanings people give to them.
• Charles Winick, an American anthropologist who compiled the Dictionary of Anthropology (1956), described it as the study of social behaviour, especially through the systematic comparison of social forms and institutions.
• A.R. Radcliffe-Brown, the British founder of structural-functionalism, called social anthropology “comparative sociology” and a “theoretical natural science of human society” (A Natural Science of Society, lectures of 1937, published 1957). He meant that societies can be studied like natural systems, to find general laws.
• E.E. Evans-Pritchard, the Oxford anthropologist known for his work on the Nuer of Sudan, defined it as the branch of sociological studies that devotes itself chiefly to primitive societies (Social Anthropology, 1951). Unlike Radcliffe-Brown, he argued that it is closer to history than to natural science, because it interprets meanings rather than discovering laws (Unit 1.2).
• Because humans always have culture and always live in societies, in a broad sense all anthropology is socio-cultural. Within the discipline, the label marks those who study existing or recent ways of life rather than fossils or ancient sites.

The two names of the branch reflect two national traditions. The table shows how they differed and how they have since come together.

Basis	Social anthropology (British)	Cultural anthropology (American)
Key concept	Social structure: the network of relations and institutions	Culture: learned traditions, values, symbols
Founders	Radcliffe-Brown, Malinowski, Evans-Pritchard	Boas, Kroeber, Benedict, Mead
Relation of the two	Culture as an aspect of social structure	Society as an aspect of culture
Typical question	How does an institution sustain social order?	What does a pattern mean; how did it develop?
Today	The distinction has largely merged into “socio-cultural anthropology”

The two traditions began from different starting points, not different subjects. A British social anthropologist studying a Nuer feud asked how the feud maintains order between lineages; an American cultural anthropologist studying the same feud would ask what values and meanings it expresses. Both answers are needed, which is why the labels have merged.

2.2 Ethnography, ethnology and social anthropology

These three words are easily confused. A simple way to remember them: ethnography describes one community, ethnology compares many, and anthropology generalises about all humans.

• Ethnography: the detailed descriptive account of one community, written after long fieldwork. Bronisław Malinowski, the Polish-born anthropologist who pioneered long-term fieldwork in the Trobriand Islands, set the standard with Argonauts of the Western Pacific (1922). S.C. Roy‘s The Mundas and Their Country (1912) is the Indian landmark: Roy, a Ranchi lawyer, became the first major Indian ethnographer of tribal life.
• Ethnology: in Evans-Pritchard’s sense, the classification of peoples by racial and cultural traits and the explanation of their present distribution by migration and diffusion (the spread of traits from one group to another). Its reconstructions are conjectural: for peoples without written history, several contrary hypotheses can fit the same facts, so ethnology can tell us what may have happened, not what did.
• Social anthropology: studies a custom as part of the whole social life of a people today. For the ethnologist, a custom plotted on a distribution map is evidence of past contact between peoples. For the social anthropologist, it matters as a working part of a social system, whatever its origin. For example, if a bride-price custom is found in several neighbouring tribes, the ethnologist asks who borrowed it from whom, while the social anthropologist asks what it does today: how it links two families, stabilises the marriage and moves wealth.
• Claude Lévi-Strauss, the French founder of structuralism, treated the three as stages of one enterprise: ethnography (observation and description), ethnology (synthesis and comparison) and anthropology (general knowledge of humankind) (Structural Anthropology, 1958).
• In American usage, “ethnology” is often simply a synonym for cultural anthropology.

2.3 Scope

What the branch tries to do. Its classic aims are to describe cultures in their present form; to study culture contact and change (what happens when societies meet); to reconstruct social history where records are missing; and to search for general regularities that hold across cultures. Its method is to study every aspect of one culture together (holism) and then compare across cultures.

As the branch grew, specialists began to focus on one area of social life each. The table lists the main sub-fields with an Indian study for each.

Sub-field	Studies	Indian anchor
Kinship and social organisation	Marriage, family, descent, alliance	Irawati Karve, Kinship Organisation in India (1953)
Economic	Production, exchange, reciprocity	Jajmani system (Wiser, The Hindu Jajmani System, 1936)
Political and legal	Power, authority, dispute settlement	Tribal councils; PESA gram sabhas
Religion	Belief, ritual, magic, shamanism	Vidyarthi’s nature–man–spirit complex (The Maler, 1963)
Psychological	Individual, personality and culture	Culture-and-personality, later cognitive studies (§6)
Ecological	Culture as adaptation to environment	Shifting cultivation of the Dongria Kondh (Odisha)
Medical	Illness, healing, health systems	Ethno-medicine; sickle cell outreach (§3)
Urban, development, visual, digital	Cities, planned change, images, online life	Village studies (Srinivas, S.C. Dube, Indian Village, 1955)

The sub-fields are lenses, not separate subjects. In a real community, the economy, kinship, politics and religion are bound together: the jajmani system, for instance, is at once an economic exchange, a caste hierarchy and a ritual relationship. A specialist therefore starts from one lens but must keep the whole society in view, which is the holistic habit that distinguishes the branch.

Why “primitive” societies were studied first

• In anthropology the word primitive was a technical term. It meant societies that are small in scale, with simple technology and economy, little specialisation of work and no writing. It never meant earlier in time or inferior: such societies have as long a history as any other, and are often more developed in some respects (kinship, ritual, ecological knowledge).
• Four reasons made them the first focus:
  • they could be observed as wholes by one fieldworker, which helped in seeing how institutions fit together
  • their “otherness” sharpened observation, because unfamiliar customs are easier to notice than one’s own
  • they were disappearing under colonial and industrial pressure, so there was an urgency to record them (salvage ethnography)
  • they extend the range of variation that comparison needs: a theory of marriage is tested better against polyandry and group marriage than against monogamy alone
• Critique: the focus froze peoples as timeless isolates and often served colonial administration (Talal Asad, ed., Anthropology and the Colonial Encounter, 1973). Since the 1950s the branch studies peasants, cities, corporations and states as well: Robert Redfield on peasant society, and M.N. Srinivas and S.C. Dube on Indian villages.

2.4 The comparative method in social-cultural anthropology

Comparison is the anthropologist’s substitute for the laboratory experiment. A chemist can repeat an experiment under controlled conditions; an anthropologist cannot. Instead, the anthropologist compares societies that differ in one respect to see what follows from that difference.

How the method developed (summary of Unit 1.1 §4.2). The 19th-century evolutionists compared customs from all over the world, torn out of their context, and arranged them on a single ladder from “savagery” to “civilisation”. Boas showed in 1896 that this was unsound: similar customs can arise from different causes, so they cannot be ranked without knowing each society’s history. Later schools compared in more careful ways, as the table shows.

School	What is compared	Purpose
Evolutionists (Tylor, Morgan, Frazer)	Customs torn from context, ranked on a ladder	Reconstruct stages of human progress
Diffusionists (Graebner, Schmidt, Elliot Smith)	Distribution of traits and trait complexes	Trace historical contact and culture circles
Structural-functionalists (Radcliffe-Brown, 1951)	Whole social structures, synchronically (at one point in time)	Find general laws of social life
Controlled comparison (Fred Eggan, 1954)	Societies within one region sharing history	Hold background constant; isolate variables
Cross-cultural survey (G.P. Murdock)	Coded samples of world societies	Statistical tests of correlations

The table shows comparison becoming more careful over time. The evolutionists and diffusionists compared single traits taken out of context, and used them to write conjectural history. Later schools compared whole systems (the functionalists), compared within a controlled region (Eggan), or compared many cases statistically (Murdock). The direction of change is from reconstructing the past to explaining how societies work.

• Fred Eggan (American; Pueblo societies) compared neighbours with a shared history, so their differences could be traced to specific causes, much like a controlled experiment. G.P. Murdock (American, Yale) built the Human Relations Area Files (HRAF), a coded archive of ethnographies for statistical testing across hundreds of cultures.

Gopala Sarana, an Indian anthropologist at Lucknow University who wrote the standard study of comparison, The Methodology of Anthropological Comparisons (1975), classified all these methods into three types according to how the cases are chosen: picked to illustrate a point, all cases in one bounded area, or a statistical sample of the world (hologeistic, from Greek holo, whole, and geo, earth).

Type	How it works	Example	Merit	Demerit
Illustrative comparison	Cases chosen to illustrate a point	Frazer, The Golden Bough	Rich, quick to build	Selection bias; proves nothing
Complete-universe comparison	Every unit in a bounded universe	Eggan on the Western Pueblo; Schapera on Bantu Africa	Context kept; no sampling error	Limited to one region; hard to generalise
Hologeistic (sampled) comparison	Statistical sample of world cultures	Murdock, Social Structure (1949), 250 societies; the HRAF files	Tests hypotheses worldwide	Coding strips context; units unclear

The three types trade depth against breadth. Illustrative comparison is easy but can prove anything, because the author chooses only the cases that fit. Complete-universe comparison keeps each custom in its context but covers one region only. Hologeistic comparison covers the whole world and allows statistical tests, but to code hundreds of societies it must reduce rich customs to simple categories, and it is often unclear what counts as one “society”.

• Galton’s problem (raised by Francis Galton in 1889 when Tylor presented a statistical comparison): societies may share a trait because one borrowed it or both inherited it, not because it has the same cause in each. Such cases are not independent, so statistics can mislead. For example, if ten societies in a sample practise cross-cousin marriage because all ten descend from one ancestral group, they are really one case counted ten times, and any correlation built on them is inflated.
• Radcliffe-Brown‘s classic illustration (1951): Australian Aborigines divide society into two halves (moieties) named after the Eaglehawk and the Crow, two birds seen as rivals yet related. He compared this with paired oppositions in other societies and found a general principle of opposition and unity: groups are defined by being both opposed and linked.
• Sarana concluded that comparison is inescapable in anthropology. Among the three types he favoured complete-universe comparison, because it keeps each custom in its context while still allowing generalisation.

2.5 Two approaches within the branch

Two debates, about where theory comes from and what culture is, run through the branch.

• Empiricism: the British view that theory must be built inductively (step by step, from observed facts upward) from field data. Malinowski’s long fieldwork and Radcliffe-Brown’s classification of social types followed this path.
  • Edmund Leach (British; highland Burma) mocked endless typing of societies as “butterfly collecting” (Rethinking Anthropology, 1961): sorting specimens without explaining them. His point was that a list of types (patrilineal, matrilineal, and so on) says nothing about why a society works as it does; classification had become a substitute for theory.
  • Lévi-Strauss‘s structuralism was the rationalist reply: the real structures of society are models in the mind, which the analyst reaches by reasoning, not by counting observed facts.
• Cognitive approach (also called ethnoscience or the new ethnography, 1950s–60s): culture is what one must know in order to behave acceptably among a people (Ward Goodenough, an American anthropologist, 1957). Culture is thus treated as knowledge in people’s heads, like the grammar of a language.
  • Method: componential analysis (breaking terms into their meaning components, e.g. a kin term into sex, generation and side of the family), used by Goodenough and Floyd Lounsbury (1956); folk classifications such as Harold Conklin‘s study of colour categories among the Hanunóo of the Philippines (1955).
  • Implication: an emic description, that is, one built from the insider’s own categories rather than the observer’s.
  • Critique: the neat formal models may not match what is really in people’s minds; Robbins Burling asked whether they were “God’s truth or hocus-pocus?” (1964). The approach also neglected actual behaviour and power. Burling’s point was that several different models can fit the same set of kin terms equally well, so there is no way to know which one is in people’s heads; and knowing the rules of a culture does not tell us what people actually do or who benefits.

2.6 Relevance

What use is the study of living cultures? Its main value is that it shows policy-makers and planners how a community actually works from the inside.

• Policy for tribal and rural India: anthropological fieldwork underlies Fifth and Sixth Schedule administration, the identification of Particularly Vulnerable Tribal Groups (PVTGs) and the Forest Rights Act process.
  • In the Niyamgiri case (Supreme Court, April 2013), the Dongria Kondh gram sabhas (village assemblies) were asked to decide on bauxite mining because the hill is their deity, Niyam Raja; all rejected it. The case turned on what the hill meant to the community, which is what ethnography provides.
• Institutions: the Anthropological Survey of India (1945); the People of India project under K.S. Singh (launched 1985) profiled 4,635 communities.
• Displacement and rehabilitation, health, education and disaster response need an insider view; plans made without it often fail.
• Business and design: Genevieve Bell, an Australian anthropologist at Intel, studied how people in different cultures use technology, to guide product design.
• Ethics debate: the US Army’s Human Terrain System (2007–2014) embedded social scientists with troops in Iraq and Afghanistan. The American Anthropological Association condemned it in 2007 as incompatible with its ethics code, because research subjects could not freely consent and could be harmed.

3. Biological Anthropology

3.1 Meaning and development

• Biological (physical) anthropology is the oldest branch. It studies humans as a biological species in a cultural setting: the comparative science of humans as physical organisms in relation to their total environment, social, cultural and physical.
• Founders: Buffon (French naturalist); Johann Blumenbach (German physician who classified humans by skull form, often called the father of physical anthropology); Samuel Morton (American skull-measurer, craniometry); Paul Broca (French surgeon, Société d’Anthropologie de Paris, 1859); Darwin and Wallace (evolution by natural selection).
• Name change: “physical” stressed measuring the body; “biological” stresses evolution, genetics and adaptation. The American Association of Physical Anthropologists became the American Association of Biological Anthropologists in 2021.
• What sets it apart from other human biology: medicine studies disease in individuals, and anatomy studies the standard human body. Biological anthropology studies the normal variation between populations and always asks how culture shapes it.

3.2 From measurement to science: how the agenda changed

For its first century, physical anthropology mostly measured bodies and sorted people into racial types. From about 1950 it became a science of populations and evolutionary processes. Understanding this shift explains most of what the branch does today.

Washburn’s “New Physical Anthropology” (summary of Unit 1.1 §4.4). Sherwood Washburn, an American physical anthropologist, argued in 1951 that the field should stop measuring for its own sake and should instead ask questions about how and why human bodies change. He drew on the Modern Synthesis (the union of Darwin’s natural selection with Mendelian and population genetics, completed in the 1930s–40s), which explains evolution as changes in gene frequencies within populations. The table contrasts the two phases.

Classical physical anthropology (to c. 1950)	New physical anthropology (from Washburn, 1951)
Anthropometry (measuring the body) as an end in itself; static racial typology	Populations, variation and evolutionary process
Lasker‘s five areas: form of bones and teeth; age, sex and ethnic group from bones; growth; body composition; body build for human engineering. Plus dermatoglyphics (finger- and palm-print patterns)	Serology (blood groups); biochemical genetics of polymorphisms; mutation, selection, gene flow; primatology; demographic genetics of inbreeding and drift; anthropometry linked to nutrition; ecology of biological and cultural adaptation
Describes what a trait is	Explains why: function and adaptation

The key contrast in the table is between typology and process. Classical work assumed that each race had a fixed “type”, and that careful measurement would reveal it. The new approach assumed that populations change constantly through mutation, selection, migration and drift, so the task is to explain how and why a trait came to vary, not to sort people into boxes.

• Gabriel Lasker, an American biological anthropologist, listed the classical areas of interest shown in the table.
• Example: classical work measured brow ridges (the bony ridges above the eyes) in isolation. The new approach recognised that brow ridges depend on the size and shape of the skull and face as a whole, and must be read functionally, in terms of chewing forces and skull growth.
• Old data were not discarded: Lasker’s areas still supply data for new questions. Classification remains the first step, but it is now followed by a problem and its interpretation.

Milestones in the scientific turn

• Boas (1911): he measured the head form of immigrants’ children in the USA and found it changed with the new environment. This showed plasticity (the body’s capacity to change with conditions) in a trait thought to be a fixed racial marker.
• 1950: the Cold Spring Harbor symposium joined geneticists and anthropologists; W.C. Boyd classified populations by blood-group genes; Coon, Garn and Birdsell treated races as adapted populations; the UNESCO Statement on Race rejected racial hierarchy.
• 1951: Washburn, “The New Physical Anthropology”.
• 1958: Frank Livingstone, an American anthropologist, linked the sickle-cell gene, malaria and yam cultivation in West Africa. The mechanism: a person with one copy of the sickle-cell gene resists malaria; a person with two copies suffers sickle-cell disease. Where malaria is common, carriers survive and have children more often, so the gene stays common despite the disease it causes. Forest clearing for yam farming spread malaria, and with it the gene.
• 1964–74: the Human Adaptability section of the International Biological Programme studied populations at high altitude (Andes, Ethiopia, Nepal), in cold (Inuit) and in heat.
• Molecular era: the molecular clock (dating splits from protein differences; Sarich and Wilson, 1967); mitochondrial Eve (the common maternal ancestor of living humans, in Africa; Cann, Stoneking and Wilson, 1987); the Neanderthal genome (2010); Svante Pääbo‘s Nobel Prize (2022) for ancient-DNA work.

3.3 Branches and scope

The older textbook division of the branch is threefold, and is still used in answers:

• Palaeontology (study of extinct forms): fossil humans and fossil primates.
• Neontology (study of living forms): anatomy, variation, genetics, growth and adaptation of living humans.
• Ethology (study of behaviour), today usually called primatology: behaviour of monkeys and apes in the wild and in captivity, which helps explain the origins of human social life.

Modern biological anthropology has many more specialised fields. The table lists them with an Indian example for each.

Branch	Studies	Indian anchor
Palaeoanthropology (human palaeontology)	Fossil hominins, the evolutionary record	Narmada hominin, Hathnora (Arun Sonakia, GSI, 1982)
Primate palaeontology	Fossil primates	Siwalik fossil apes such as Sivapithecus
Primatology (ethology)	Behaviour and biology of living primates	Sarah Hrdy, The Langurs of Abu (1977): infanticide by langur males
Human population genetics	Gene frequencies, mating systems, drift	Reich et al. (2009): ANI–ASI ancestral components; caste endogamy produced strong founder effects (2017)
Human adaptability and ecology	Adaptation to altitude, heat, cold, disease	High-altitude adaptation in Himalayan populations
Growth and nutrition (auxology)	Growth, maturation, nutritional status	NFHS-5 (2019–21): 35.5% of children under five stunted
Forensic anthropology	Identifying age, sex, stature from remains	Mass-disaster and crime identification
Kinanthropometry and ergonomics	Body build for sport and design	Equipment sizing (Unit 12)
Serology and dermatoglyphics	Blood groups, finger-ridge patterns	D.N. Majumdar’s anthropometric and serological survey of UP (1941) with P.C. Mahalanobis
Palaeopathology and bioarchaeology	Disease and life from skeletons	Harappan skeletons (§4.5)

The table shows the branch moving from bones to genes to bodies in society. Palaeoanthropology works with millions of years, population genetics with thousands, and growth and forensic studies with a single lifetime. What links them is the question of variation: how and why human bodies differ across time, space and social conditions.

• ANI and ASI (Ancestral North and South Indians): two ancient populations whose mixing, in different proportions, accounts for most Indian ancestry today.
• Founder effect: a population’s genes reflect its few founders; centuries of caste endogamy (marriage within the group) let rare disease genes become common within one group.
• Stunting: low height for age, a marker of long-term undernutrition.

3.4 The bio-cultural approach

Example first. Sickle-cell disease is common among tribal communities of central and western India. To understand why, one needs both biology and culture. The sickle-cell gene protects carriers against malaria; malaria was endemic in the forested areas where these communities live; and forest clearing for cultivation increases mosquito breeding. Biology alone or culture alone cannot explain the pattern; the two together can.

• Core idea: human biology cannot be explained without culture, and culture often responds to biology. The task is to explain the interplay, not to divide traits neatly into “heredity” and “environment”.
• Culture shapes biology:
  • mating rules and inbreeding: cross-cousin and uncle–niece marriage in South India raise homozygosity (inheriting the same gene version from both parents), so recessive disorders appear more often (Units 2.3 and 9)
  • diet and food taboos; body modification
  • migration and settlement history
  • dairying selected for lactase persistence (the ability of adults to digest milk), an example of gene–culture co-evolution: once people kept cattle and drank milk, adults who could digest it had a survival advantage, so the gene spread in herding populations
  • forest clearing for cultivation spread malaria and so favoured the sickle-cell allele (Livingstone)
• Biology shapes culture: disease loads shape settlement, ritual and health practices; growth and nutrition shape work and fertility.
• Indian application: the National Sickle Cell Anaemia Elimination Mission (launched 1 July 2023 at Shahdol, MP) aims at elimination by 2047. By July 2025 about 6 crore people had been screened. Its counselling depends on understanding marriage customs in the affected communities, a bio-cultural task.
• Critique and caution: the branch’s history includes race science:
  • Morton’s ranking of races by skull size
  • H.H. Risley, a British colonial official, used the nasal index (nose width relative to height) to rank castes (The People of India, 1908)
  • eugenics, the discredited programme of “improving” populations by controlling who may reproduce

Modern biological anthropology rejects racial typology and studies clines (gradual geographic change in a trait) and populations instead (Unit 9).

4. Archaeological Anthropology

4.1 Meaning

• Archaeological anthropology reconstructs past ways of life from material remains. These remains fall into three types:
  • artefacts: objects made or used by people (tools, pottery, ornaments)
  • ecofacts: natural remains that reveal human activity (seeds, pollen, animal bones, charcoal)
  • features: things that cannot be lifted out of the ground (hearths, pits, walls, burials)
• It is the “past tense of cultural anthropology”: it asks the same questions about economy, society and belief, but with different evidence. A cultural anthropologist can ask people; an archaeologist must read objects.
• Why it is indispensable: writing began only about 3000 BCE in West Asia, and much later elsewhere (Australia not until 1788 CE). For over 99% of the human past, material remains are the only record.
• Lewis Binford, an American archaeologist who led the “New Archaeology”, argued in “Archaeology as Anthropology” (1962) that archaeology’s goal is the anthropological explanation of culture change, not just the collection of objects.
• Archaeologists work with many specialists: geologists, palynologists (pollen experts), zoologists, chemists and physicists for dating (Unit 1.8).

4.2 Divisions and specialisations

• By period (Indian usage):
  • prehistoric: before writing
  • protohistoric: writing exists but is undeciphered, or the people are described only by outsiders (e.g. the Harappans, whose script is unread)
  • historical: periods with readable written records
• A four-way division by the role of texts:
  • prehistoric (from the first humans to writing)
  • text-aided or classical (literate civilisations, where texts guide the excavation)
  • text-free (non-literate peoples of the Old and New Worlds, known only from digging)
  • salvage (rescuing sites threatened by dams, roads or erosion before they are lost)

Within archaeology, many specialisations have grown up. Each uses a different kind of evidence or setting, as the table shows.

Specialisation	Focus	Example
Ethnoarchaeology	Living people’s material culture to interpret the past	Binford among the Nunamiut (Alaska): butchery and bone refuse; megalith-raising as a living tradition among the Khasi and Naga (North-East India)
Environmental archaeology	Past climate, plants and animals around sites	Pollen, snails and rodents as climate indicators
Underwater (marine) archaeology	Submerged sites and shipwrecks	Dwarka (Gujarat): S.R. Rao’s offshore work from the 1980s; ASI explorations resumed 2025
Garbology	Archaeology of modern waste	William Rathje’s Garbage Project, Tucson (from 1973): households under-reported their beer drinking compared with what their bins showed
Experimental archaeology	Replicating tools and processes	Knapping stone tools to read use-wear
Bioarchaeology	Human remains in their cultural context	Diet, disease and kinship from skeletons and ancient DNA

Each specialisation answers a gap in the evidence. Bones and tools alone cannot tell how they came to lie where they did, so ethnoarchaeology watches living people; sites alone do not show the landscape, so environmental archaeology reconstructs it; some evidence lies underwater or in modern bins, so special methods were built for those settings. Together they widen what can be known about the past.

• Why ethnoarchaeology matters: excavated bones do not explain themselves. Watching living hunters butcher and discard, Binford learned which patterns in a site come from human activity and which from natural processes. Garbology shows the same methods work on the present: what people throw away is more honest than what they say.

4.3 Old, new and post-processual archaeology

Archaeology’s aims have changed in three broad phases, from describing the past, to explaining it scientifically, to interpreting its meanings.

Phase	Approach	Key figures
Culture-historical (to c. 1960)	Description and chronology of cultures; spread explained by diffusion and migration	Childe; in India, Wheeler
Processual or New Archaeology (1960s)	Culture as an adaptive system; evolutionary and ecological focus; hypothetico-deductive testing (stating a hypothesis, then testing it against evidence); ethnographic analogy	Binford (1962); David Clarke, Analytical Archaeology (1968)
Post-processual (1980s)	Meaning, symbols, agency, gender; many interpretations; the archaeologist’s own position	Ian Hodder, a British archaeologist

• Processualists faulted the older approach for listing cultures and dates without asking why change happened; post-processualists faulted them in turn for treating people as parts of a system and ignoring what objects meant to their makers. For instance, a processualist might explain a burial with rich grave goods as a sign of economic surplus, while a post-processualist would ask what the goods symbolised to the mourners and whose view of the past the explanation reflects.

4.4 Field methods

Example first. At Rakhigarhi in Haryana, one of the largest Harappan sites, archaeologists surveyed the mounds, excavated houses and a cemetery layer by layer, recorded every find, dated the layers, and finally extracted ancient DNA from a skeleton in the laboratory. Each of these is a stage of archaeological method, shown in the sequence below.

1. Exploration and survey: finding sites before digging: surface walking, satellite imagery, LiDAR (airborne laser scanning that sees through vegetation), ground-penetrating radar, magnetometry, place-names and local knowledge.
2. Excavation:
   • vertical excavation (deep, narrow trenches) to establish the sequence of layers
   • horizontal (open-area) excavation to expose the layout of a settlement at one period
   • Mortimer Wheeler, the British archaeologist who headed the Archaeological Survey of India in the 1940s, introduced the grid or box system in India. He trained Indian archaeologists at the Taxila school (1944) and excavated Arikamedu (1945)
3. Stratigraphy: the study of layers. By the law of superposition, lower layers are older than those above them, unless disturbed (by pits, burrowing animals or floods). So even without a date in years, the order of layers tells which objects are earlier and later; this is the basis of relative dating. Layers are recorded and ordered, today often with a Harris matrix (a diagram showing the sequence of layers).
4. Recording and sampling: the 3-D position of every find, section drawings, photogrammetry, flotation (floating soil in water to recover charred seeds). Excavation destroys the site, so the record is all that survives.
5. Dating: relative methods give order (stratigraphy, typology, fluorine); absolute methods give years (radiocarbon, potassium–argon, luminescence, dendrochronology). Detail in Unit 1.8.
6. Laboratory analysis:
   • typology (sorting objects by form) and use-wear (microscopic traces showing how a tool was used)
   • zooarchaeology (animal bones) and archaeobotany (plant remains)
   • stable isotopes in bones and teeth, which reveal diet and movement
   • ancient DNA
7. Interpretation and publication: working out formation processes (how natural and human actions created the site), using ethnographic analogy and building models. Ethics: consent and involvement of descendant communities.

4.5 Relevance

• Deep-time view of adaptation: how societies met climate change and collapse. A drying phase around 4,200 years ago is debated as a factor in Harappan de-urbanisation (cities declining into villages).
• Ancient DNA joins archaeology to biology: the Rakhigarhi genome (Shinde et al., Cell, 2019) showed no steppe pastoralist ancestry (ancestry from the Central Asian grasslands). It carried an ancestry related to early Iranian groups that split before farming began, suggesting farming in South Asia arose largely locally.
• Heritage and identity: protection of sites, museums, tourism and community memory; underwater cultural heritage.
• Salvage before development (Nagarjunakonda) and forensic archaeology in crime and disaster investigation.
• Critique: interpretations are built from fragmentary and biased samples, since only durable materials survive; and the past can be pulled into nationalist or identity politics.

5. Linguistic Anthropology

5.1 Meaning

• Linguistic anthropology is the study of language as a cultural resource and speaking as a cultural practice (Alessandro Duranti, an Italian-American linguistic anthropologist, Linguistic Anthropology, 1997).
• How it differs from linguistics: linguistics studies the history, structure, variation and meaning of language apart from its social setting. Linguistic anthropology studies the same things inside social and cultural contexts.
• Unlike the polyglot (who simply speaks many languages) or the philologist (who studies language through literature and old texts), the linguistic anthropologist asks how language relates to the rest of culture.
• Roots: Boas, Handbook of American Indian Languages (1911), recording unwritten languages; his student Edward Sapir, Language (1921); and Sapir’s student Benjamin Lee Whorf, on language and thought.
• Name: the field was called “anthropological linguistics” until Dell Hymes, an American linguist-anthropologist, argued in 1964 for “linguistic anthropology”, to stress that the questions should be anthropological ones.

Alessandro Duranti divided the history of the branch into three phases, each with a different main interest. The table summarises them.

Paradigm	Period	Focus
1. Documentation	Boas to the 1950s	Recording and describing unwritten languages; grammars, texts, dictionaries
2. Ethnography of communication	1960s onward	Variation and language use in speech events: Gumperz and Hymes (1964, 1972); Hymes’s SPEAKING model
3. Language as social action	1990s onward	Identity, power, ideology, socialisation through talk

The three paradigms show the branch moving from the dictionary to the conversation. The first asked what a language is: its sounds, words and grammar. The second asked how language is used in real situations, such as a ritual or a village dispute. The third asks what speaking does: how it builds identities, signals power and passes on culture to children.

• Hymes’s SPEAKING model is a checklist for describing any speech event: Setting, Participants, Ends (purposes), Act sequence, Key (tone), Instrumentalities (channel and variety), Norms and Genre.

5.2 Branches

Each branch of linguistic anthropology asks a different question about language. The table lists them with an example each.

Branch	Studies	Example
Historical (comparative) linguistics	Language change, families, reconstruction of proto-languages; glottochronology (Swadesh)	Indo-European, Dravidian, Austroasiatic, Tibeto-Burman families; Grierson’s Linguistic Survey of India (1894–1928)
Descriptive (structural) linguistics	Phonology, morphology, syntax: how sounds make words and words make sentences	Grammars of tribal languages such as Santali and Kurukh
Sociolinguistics	Speech variation by class, caste, gender, situation	Labov, New York (1966); Gumperz, Khalapur (UP, 1958): caste groups marked by dialect differences
Ethnosemantics (ethnoscience)	How a people classify their world: plants, colours, illness, kin	Berlin and Kay, Basic Color Terms (1969)
Psycholinguistics	Acquisition and processing of language	Language socialisation (Schieffelin and Ochs, 1986)
Ethnography of communication	Who speaks, how, when, to whom, for what purpose	Hymes’s SPEAKING grid
Language and thought	Whether language shapes perception	Sapir–Whorf hypothesis (Unit 7)

The first two branches study language itself (its history and structure); the rest study language in relation to society and the mind. The linguistic anthropologist uses both: a careful description of a language is needed before one can study how it varies by caste or how it shapes a people’s classification of the world.

• Proto-language: the reconstructed ancestor of a language family, e.g. Proto-Dravidian, rebuilt by comparing Tamil, Telugu, Kannada and Malayalam words. Glottochronology (Morris Swadesh, American linguist) dates such splits from the rate at which basic words are replaced; it is used with caution because the rate is not constant.
• William Labov (American linguist, 1966) found New Yorkers pronounced the “r” in “fourth floor” more often in higher-status stores: speech varies systematically with class. John Gumperz found the same for caste in Khalapur.
• Sapir–Whorf hypothesis: the language we speak shapes how we perceive and think (Unit 7 treats it in detail).
• South Asia as a “linguistic area”: M.B. Emeneau, an American scholar of Dravidian languages, showed in 1956 that unrelated language families in India share features such as retroflex sounds (made with the tongue curled back), because of centuries of contact.

5.3 Language use in social and cultural settings

Example first. In a Hindi-speaking household, a child calls a younger sibling tū, a friend tum, and a teacher āp. The choice of one small word shows intimacy, equality or respect. This is what linguistic anthropologists mean by language use in social settings: the same message changes meaning depending on who speaks to whom.

• Status and respect: Hindi tū / tum / āp encode intimacy and hierarchy; Brown and Gilman (American psychologists, 1960) called such pronouns markers of power and solidarity.
• Caste and dialect: in Khalapur, Gumperz found speech differences tracking caste and touchability, not just region. Speech can mark social boundaries as clearly as dress or food.
• Code-switching: shifting between languages mid-conversation to signal identity or change the frame, as between English and Hindi (Gumperz). A manager may give instructions in English but switch to Hindi to joke or show warmth; the switch itself carries social meaning.
• Diglossia: a high variety of a language for formal and written use alongside a low variety for everyday speech (Charles Ferguson, an American linguist, 1959). Tamil, with its literary and spoken forms, is a standard Indian case.
• Kinship terms as social categories: Irawati Karve, the pioneering Indian anthropologist, contrasted northern and southern Indian kin vocabularies and linked them to different marriage rules (Unit 2.5).
• Avoidance: in many north Indian households a wife does not utter her husband’s name.
• Language and political identity:
  • linguistic reorganisation of states (1956)
  • Santali in the Eighth Schedule (2003), written in the Ol Chiki script

5.4 Structuralism in linguistics and in social anthropology

Structuralism is an approach that looks for the hidden system of relations behind what we observe. It began in linguistics and was then borrowed by social anthropology, which is why the two fields are often compared.

• Source in linguistics:
  • Ferdinand de Saussure (Swiss linguist): signs mean through differences (“cat” is not “bat”); langue (the shared system) vs parole (individual speech); synchronic analysis (a system at one time).
  • the Prague school (Trubetzkoy, Jakobson): phonemes (basic sound units) are bundles of binary distinctive features, such as voiced vs unvoiced.
• Borrowing in anthropology: Lévi-Strauss, in “Structural analysis in linguistics and in anthropology” (1945), argued that kinship terms are like phonemes. They mean something only as parts of systems and are generated by unconscious rules. From this came his atom of kinship (the basic unit of brother, sister, her husband and their son, which explains the avunculate, the special tie between mother’s brother and sister’s son) and his analysis of myths into mythemes (the smallest units of a myth).

The analogy works in some respects and fails in others, as the table shows.

Common ground	Where the analogy fails
Elements defined by relations, not by themselves	Kinship and myth carry content, power and sentiment, not only contrasts
Binary oppositions	Social systems change through history; phonology is relatively closed
Unconscious structure behind conscious usage	Structures are hard to verify in observed behaviour
Synchronic analysis	Leach and others: too formal, ignores individual choice

The analogy is strongest where both language and kinship are systems of relations: a kin term like “mother’s brother” means something only in contrast with “father” and “father’s brother”, just as a phoneme is defined by contrast with other phonemes. It is weakest where social life involves feelings, interests and change. People choose whom to marry, quarrel over inheritance and alter customs, while speakers do not choose their phonemes, so a model built for sounds can miss the human agency in society.

• Gopala Sarana (1965) noted that structuralism in linguistics and functionalism in anthropology grew from a similar concern: to see each element as part of a working system.

5.5 Relevance

• Fieldwork depends on language: a people’s own categories, kin terms and ritual vocabulary are the social anthropologist’s data. Malinowski insisted on learning the local language for exactly this reason. This is the core of the relationship between linguistics and social-cultural anthropology (§7).
• Endangered languages:
  • Boa Sr, last speaker of Bo (a Great Andamanese language), died in 2010; with her went a body of knowledge about the islands
  • the People’s Linguistic Survey of India (G.N. Devy, from 2010) recorded about 780 languages
  • the Scheme for Protection and Preservation of Endangered Languages (CIIL, 2013)
• Education: children learn best in the language they speak at home. Multilingual education in tribal mother tongues (Odisha) and NEP 2020, which prefers the home language as the medium of instruction at least up to Grade 5, apply this finding.
• Health and law: culturally fitted health messages; language in courts and police interviews; language technology for low-resource languages (languages with little digital text).

6. Applied, Action and Other Branches

Most of these branches draw on all four main fields, which is why they are listed separately. The table summarises them.

Branch	Meaning	Key points
Applied anthropology	Use of anthropological knowledge to solve practical problems	Malinowski, “Practical Anthropology” (1929); in India, tribal administration, Tribal Research Institutes, impact assessment; detail in Unit 12
Action anthropology	Research with a community to meet its goals while learning from the process	Sol Tax, Fox (Meskwaki) Project, Iowa (1948–59); the community, not the anthropologist, decides
Medical anthropology	Health, illness and healing in cultural context	Ethno-medicine, illness narratives, health programmes, epidemics
Psychological anthropology	Culture and the individual mind	From culture and personality (Benedict, Mead, Kardiner) to cognitive, psychiatric and cultural-psychology studies
Applied physical anthropology	Biological knowledge put to use	Forensics, ergonomics, sports, nutrition (Unit 12)

These branches are defined by purpose, not by evidence or method: each borrows from the four main fields to address a practical concern, such as health, development or the mind.

• Applied vs action anthropology: in applied work, the anthropologist usually advises a government or agency, which then decides. In action anthropology, as Sol Tax (an American anthropologist at Chicago) practised it among the Meskwaki, the community sets the goals and the anthropologist helps while learning. The difference lies in who holds the power to decide.
• Recent trends in psychological anthropology: the early culture-and-personality school gave whole nations one personality type, criticised as stereotyping. Later work turned to cognition within a culture, mental illness across cultures, and how culture and mind make each other.
• Medical anthropology asks why people choose one form of healing over another and why health programmes succeed or fail; in India it is central to tribal health and sickle-cell counselling.

7. Synergy of the Branches: Reviving Holism

One case, four branches: the Andaman Islands

• Social-cultural: Radcliffe-Brown, The Andaman Islanders (1922): ritual and myth as expressions of social sentiment, the feelings that hold a society together.
• Biological: Thangaraj et al. (Science, 2005) found unique mitochondrial lineages (M31, M32) among the Onge and Great Andamanese. Mitochondrial DNA is inherited through the mother, so these lineages trace an unbroken maternal line pointing to an early out-of-Africa dispersal.
• Linguistic: Anvita Abbi, an Indian linguist, showed that Great Andamanese and Ongan (Onge, Jarawa) are separate language families; the Bo language died with Boa Sr in 2010.
• Archaeological: late-Holocene shell middens (refuse heaps of shells and other food waste), studied by Zarine Cooper, record foraging and pottery over centuries.
• Together they answer what no branch can alone: who the islanders are, how long they have been there, and what threatens them now.

Why the branches need each other. Each pair of branches exchanges something essential, as the table shows.

Pair	What each gives the other
Linguistic ↔ social-cultural	Language gives access to emic categories; structuralism and ethnoscience came from linguistics; kin terms are social data
Archaeological ↔ social-cultural	Archaeology adds time depth; ethnography supplies analogies (ethnoarchaeology)
Biological ↔ social-cultural	Culture explains mating, diet and disease patterns; biology tests claims about “race” and caste origins
Biological ↔ archaeological	Skeletons, isotopes and ancient DNA tell who lived at a site (Rakhigarhi)
Linguistic ↔ biological / archaeological	Language families, genes and material cultures together trace population history

The table makes one point clear: no branch is self-sufficient. Archaeology without ethnography has no living analogies to interpret its finds; genetics without archaeology cannot place ancestry in time and place; socio-cultural study without language cannot reach people’s own meanings. Each branch fills a gap that the others leave.

• Pressures toward fragmentation: specialisation (separate journals, methods and jargon); Stanford split its department in 1998 and reunited it about a decade later; the American Anthropological Association‘s 2010 debate over dropping “science” from its mission showed the gap between scientific and interpretive anthropologists. Fragmentation matters because the questions that matter most, such as caste and health, migration or climate adaptation, cross branch lines; a discipline split into separate camps loses the holistic view that is its chief strength.
• Indian situation: integrated teaching survives, but under-equipped laboratories push biological anthropologists into survey-type work that imitates socio-cultural research. Real integration needs teams of specialists around shared problems, such as endemic and community-specific diseases, rather than one generalist doing everything.
• Ways of synergising:
  • the biocultural synthesis (Alan Goodman and Thomas Leatherman, 1998), which studies how social inequality and political economy shape human biology
  • ancient DNA joined to archaeology and linguistics, as at Rakhigarhi
  • ethnoarchaeology, joining living cultures to the archaeological record
  • forensic teamwork between biological anthropologists and archaeologists
  • community-based documentation of language, heritage and health

Contemporary Developments

• GenomeIndia (January 2025): whole genomes of 10,000 individuals from across India were archived at the Indian Biological Data Centre, Faridabad, as a reference for Indian genetic diversity.
• Sickle cell mission: about 6 crore people screened by July 2025 against a target of 7 crore; 2.15 lakh diagnosed and 16.7 lakh carriers identified, mostly in tribal belts.
• Underwater archaeology revived (February 2025): the ASI’s Underwater Archaeology Wing resumed explorations off Dwarka and Bet Dwarka, with a team that included more women archaeologists than any earlier ASI underwater team.
• Renaming: the US professional body became the American Association of Biological Anthropologists (2021), marking the shift from measurement to biology and evolution.
• Language technology: mother-tongue instruction under NEP 2020 and AI tools for low-resource languages have created new applied work for linguistic anthropologists.
