Later in the 1960s and 1970s, Edmund Leach and his students Mary Douglas and Nur Yalman, among others, introduced French structuralism in the style of Lévi-Strauss; while British anthropology has continued to emphasize social organization and economics over purely symbolic or literary topics, differences among British, French, and American sociocultural anthropologies have diminished with increasing dialogue and borrowing of both theory and methods. Today, social anthropology in Britain engages internationally with many other social theories and has branched in many directions.
