Revision summary
Morgan ranked families from group marriage to Victorian monogamy. He linked terms, property, and a three-age history of culture. No ethnography confirms consanguine or punaluan stages. Boas, Lévi-Strauss, and feminist work dismantled the ladder. Keep his comparative kinship method, not his timetable.
Model answer
Introduction
Lewis Henry Morgan ranked families from promiscuity to monogamy as stages of progress. The scheme organised a vast kinship vocabulary. As history and as ethnography it fails.
Body
What he classified
- In Ancient Society and Systems of Consanguinity, Morgan moved from the consanguine family (sibling group marriage) through the punaluan (group of brothers marrying a group of sisters), syndyasmian pairing, patriarchal, and the monogamian family.
- He tied these to savagery, barbarism, and civilisation, and to Malayan, Turanian, and Aryan kinship terms.
- Engels took the scheme into a Marxist history of the family and private property.
Critical evaluation
- Fieldwork found no consanguine or punaluan stage as a real household. Trobriand, Nuer, and Andaman families are not rungs on that ladder.
- Boas and historical particularism rejected unilinear family history. Terms can be classificatory without proving group marriage.
- Lévi-Strauss shifted the problem to alliance and incest prohibition, not to Morgan’s fossils of promiscuity.
- Weiner and feminist kinship showed that Morgan’s endpoint—Victorian monogamy as the highest family—was ethnocentric.
- What survives is the method of comparing kinship terms, the Iroquois case, and the insight that family form is social, not a natural given.
Verdict
- Use Morgan as a founder of kinship study. Do not use his five families as a timetable of humankind.

Conclusion
Morgan classified family as evolutionary stages ending in monogamy. The typology is historically false. The comparative study of terms and of property in the family is his lasting gift.

-
Did Morgan invent kinship study?
He professionalised the comparison of terms and descent. Later schools kept the data and dropped the stages.
-
Is the nuclear family the last stage?
That was his Victorian endpoint. Anthropology treats many family forms as contemporary, not as leftovers.

Critically examine James Frazer's theory of evolutionism. Elucidate the place of religion in modernity
Classical evolutionism (Tylor, Morgan and Frazer)
Frazer moved from magic as coercion, to religion as petition, to science as law, with sympathetic magic and survivals. Critique him for armchair method, unilinear stages, intellectualism and colonial ranking. Magic, religion and science coexist. The usable fragment is like-produces-like and contact. Modernity is incomplete disenchantment: civil religion, revival movements and political religion. A smartphone pilgrimage is not a fossil stage. Durkheim and Weber are better guides to religion as social fact and meaning.

Classical evolutionism (Tylor, Morgan and Frazer)
Classical evolutionism arranged societies on universal stages using decontextualised comparison. Boas argued that similar traits may have different causes and histories. His 1896 critique required fieldwork, language, distribution and chronology before comparison. The Boasian school separated race, language and culture and advanced cultural relativism. Baffin Island and Northwest Coast research replaced armchair sequence with documented context. Its limits were anti-generalisation, salvage assumptions and insufficient attention to colonial power.

Classical evolutionism (Tylor, Morgan and Frazer)
Morgan sequenced family from promiscuity to monogamy with property. Socio-political order ran gens to tribe to territorial state. Savagery–barbarism–civilisation was invention-marked. McLennan, Maine, Bachofen, and Tylor kept evolution but not his rungs. Boas and Lowie rejected unilinear necessity.
