John Ferguson McLennan

Born 14 Oct 1827; died 16 Jun 1881 at age 53.British lawyer and anthropologist who undertook a vast comparative research of the ceremonies of marriage. His theory of social evolution, in which he first used the terms exogamy (marriage outside the group) and endogamy (marriage within the group), stemmed from his interest in the survival of primitive cultures. He did much to stimulate and guide anthropological research. He developed influential theories on cultural evolution, kinship and the origin of religion. McLennan's pioneering work on totems (as survivals of primitive worship of fetishes, plants, animals and anthropomorphic gods) had a great influence upon contemporary social scientists, including Sigmund Freud. McLennan was influenced strongly by Charles Darwin's theory of evolution.
