(a) Scope and relevance of Social and Cultural Anthropology

Social and Cultural Anthropology studies living human societies comparatively, through ethnographic fieldwork: social organisation, kinship, economy, religion, politics and change. Its scope runs from small-scale tribal and peasant communities to urban and global processes, and it covers applied, medical, visual and development anthropology.

Its relevance in India is practical. Ethnographic knowledge from the Anthropological Survey of India supports the identification of Scheduled Tribes and the designing of Fifth and Sixth Schedule administration, forest-rights recognition and tribal welfare schemes. It explains the cultural dimension of displacement, health, poverty and conflict, and helps to make development and policy culturally sensitive. It also counters ethnocentrism and promotes cultural relativism and understanding among groups.

(b) Cultural impact of Iron Age

In India the Iron Age began around 1200–1000 BCE. Iron axes cleared the Ganga plain forests, and the iron ploughshare raised agricultural surplus, which supported population growth, specialised crafts, trade and later the second urbanisation (Kaushambi, Taxila, Pataliputra). Political change followed in the form of janapadas and mahajanapadas, leading to early states, standing armies and taxation.

Social stratification grew with the varna–jati order, and the settled agrarian economy changed labour division and gender roles. Religious ferment produced Buddhism and Jainism. In the peninsula, Megalithic cultures (Brahmagiri, Hallur, Adichanallur) with iron tools and burial monuments show the regional spread of iron. Iron weapons and tools also changed warfare and ritual.

(c) Race and ethnicity

Race is a classification of human populations on the basis of visible physical traits such as skin colour, hair form and skull shape. Modern anthropology, reflected in the UNESCO statements of 1950 and 1951, rejects discrete biological races: variation is clinal and continuous, most genetic variation lies within populations, and traits do not go together. Race survives as a social construct, and racism is its political use.

Ethnicity is a cultural identity based on shared language, ancestry, religion, territory and historical memory, maintained through boundaries and self-ascription (Barth). In India, tribes, castes and linguistic groups show ethnic identity, and confusing the two leads to essentialist and discriminatory policy.

(d) Customary laws and environmental conservation

Customary laws are unwritten, community-made norms on the use of land, forest, water and wildlife, enforced by social and religious sanctions. They have conserved nature through sacred groves (Law Kyntang among the Khasi, Sarna or Jaherthan among the Munda and Santhal, Devrai in Maharashtra), taboos on hunting and felling, totemic protection of species, rotational grazing, and community water systems such as the tanka of Rajasthan and the phad irrigation of Maharashtra.

Such rules work because compliance rests on belief and community pressure, not on policing. Legal recognition is seen in the Forest Rights Act, 2006, the PESA Act, 1996 and community-conserved areas, while Joint Forest Management tries to share management. Their revival supports sustainable development and climate adaptation.

(e) Gene expression

Gene expression is the process by which a gene's information is used to make a functional product, usually a protein, by transcription of DNA into mRNA and translation of mRNA into protein. It is regulated at many levels, by transcription factors, promoters and enhancers, and epigenetic mechanisms such as DNA methylation and histone modification, which change gene activity without altering the sequence.

Regulation explains cell differentiation and environmental response. Anthropologically, it underlies adaptation: Tibetan highlanders carry EPAS1 variants (encoding HIF-2α) linked to lower haemoglobin concentration, which avoids excess red-cell production at altitude, and lactase persistence shows gene–culture co-evolution in milk-drinking pastoralists.
