Talk given to the Radical Anthropology Group at Daryll Forde Seminar Room, Anthropology Building, 14 Taviton Street, London WC1H 0BW on 30 January 2018. Chris Knight, founder of the Radical Anthropology Group, interprets a Plains Indian myth. The story suggests the social transformations that occur alongside the turn from hunting to gardening and agriculture, the change from matrilocal residence to patrilocal and the institution of marriage as we still know it today: the transformation of woman into all-purpose wife. Chris Knight contrasts his interpretation with that of Claude Lévi-Strauss.
