Breaking down the question
This is a 20-mark question that asks for a conceptual discussion, not a descriptive survey. The examiner has deliberately paired two terms — lineage and descent — that students often treat as interchangeable, and the phrase conceptual issues signals that the answer must probe the analytical problems, ambiguities and debates surrounding them rather than merely define them.
The demand for suitable illustrations is equally important. India, with its striking regional and community diversity, is a testing ground where the neat models of descent theory, largely built on African material, run into difficulties. A strong answer therefore does two things at once: it clarifies the concepts of descent, filiation and lineage, and it shows, through concrete Indian examples, where these concepts strain or blur. Breadth of illustration combined with conceptual precision is what separates a top-band script here.
How to approach it
Open by distinguishing descent as a principle of tracing relationships from lineage as an actual corporate group formed on that principle. Then move to the conceptual issues — the confusion between descent and filiation, the applicability of unilineal models to India, the north–south contrast, the fit of matrilineal and bilateral cases, and the changing salience of lineage under modern conditions.
Each conceptual point should be anchored to an Indian illustration: the patrilineal gotra and lineage of the north, the Nayar taravad of Kerala, the Khasi and Garo matriliny of the north-east. Weave in the theoretical apparatus of Radcliffe-Brown and Fortes and the Indian scholarship of Irawati Karve and T. N. Madan. The note on lineage and descent in India develops this framework in detail.
Model answer
Descent is the principle by which an individual traces membership of a kin group through a socially recognised chain of parent–child links, while lineage is the concrete, often corporate group of persons who can actually demonstrate such descent from a common known ancestor. The distinction matters: descent is a rule or ideology, lineage is a group formed in accordance with it. Much of the conceptual difficulty in the Indian material arises from conflating the two, or from importing models developed elsewhere onto a subcontinent whose kinship is regionally plural.
A first conceptual issue is the difference between descent and filiation, sharpened by Meyer Fortes. Filiation is the universal fact of being someone's child and connects a person to both parents; descent, in unilineal systems, selects only one line, patrilineal or matrilineal, for group membership. In north-Indian Hindu society the patrilineal principle assigns a person to the father's gotra and lineage, yet ties to the mother's kin — the maternal uncle, the nanihal — remain socially vital. Descent theory, which stresses the single reckoned line, can obscure these complementary bonds that everyday kinship actually sustains.
A second issue concerns the applicability of the classical unilineal descent group model, elaborated by Radcliffe-Brown and the African lineage theorists, to Indian conditions. In segmentary African societies the lineage was a jural and political corporation. In India the corporate functions of the lineage are entangled with, and often subordinated to, caste, the joint family and the village, so that lineage rarely operates as an autonomous political unit. The gotra, for instance, is an exogamous descent category that regulates marriage but is not a residential or property-holding corporation, whereas the smaller localised lineage may hold ancestral land. Treating gotra and lineage as one blurs a real analytical divide.
A third and central conceptual issue is regional variation, mapped classically by Irawati Karve. The northern zone is firmly patrilineal, patrilocal and exogamous, with descent, inheritance and ritual duty passing through the male line. The southern Dravidian zone, though also predominantly patrilineal, overlays descent with a preference for cross-cousin marriage, so that affines are often existing kin and the sharp descent-based separation of wife-givers and wife-takers found in the north is softened. The same word, lineage, thus organises social life differently in the two zones, and any single model of Indian descent is bound to distort one region or the other.
The matrilineal cases press the concepts hardest. Among the Nayars of Kerala, descent, residence and property once passed through the female line within the taravad, authority lay with the mother's brother rather than the husband, and the sambandham union so loosened the conjugal tie that Kathleen Gough questioned whether Nayar arrangements even constituted marriage in the conventional sense. Among the Khasi and Garo of the north-east, matrilineal descent coexists with male political authority, producing a divergence between the line of descent and the locus of power. These illustrations show that descent, residence and authority — bundled together in the ideal-typical model — can in fact vary independently.
Further issues arise at the margins. Some communities, such as sections in Gujarat, display bilateral tendencies that fit neither pole cleanly. Muslim kinship permits parallel-cousin marriage, forbidden under Hindu north-Indian norms, complicating any pan-Indian generalisation about descent and marriage. And under urbanisation, migration and legal change — the Hindu Succession Act's grant of coparcenary rights to daughters, for example — the corporate lineage is weakening as a property-holding and ritual body even where descent ideology persists, so that the concept must now be used historically as much as descriptively. T. N. Madan's study of Kashmiri Pandit kinship illustrates how descent principles are lived and negotiated within concrete household relations rather than mechanically applied.
In sum, the conceptual issues about lineage and descent in India are those of definition, applicability and fit. Descent must be kept distinct from filiation and from the concrete lineage group; the unilineal corporate model built abroad must be applied to India with caution; regional, matrilineal and bilateral variation must be respected; and the changing salience of the lineage under modernity must be acknowledged. Indian material, precisely because it resists the tidy models, has been a valuable corrective within descent theory.
Examiner's perspective
At 20 marks the examiner is looking for genuine conceptual engagement, not a rehearsal of definitions. The scripts that reach the top band open by separating descent from lineage and descent from filiation, and then organise the answer around clearly stated issues — the limits of the unilineal model, regional contrast, the matrilineal puzzle and modern change — rather than drifting into a general essay on Indian kinship.
Illustration is the decisive discriminator. Naming and using the gotra, the Nayar taravad, and Khasi or Garo matriliny to make analytical points, and citing Karve, Fortes, Radcliffe-Brown, Gough and Madan appropriately, signals command. A weaker answer defines lineage and descent, lists a few examples and stops; the stronger answer shows why the Indian cases are theoretically interesting. Disciplined structure, precise terminology and measured British prose complete a first-class response.
