The term was first employed by the British anthropologist Edward Burnett Tylor (Tylor, Sir Edward Burnett) in his Primitive Culture (1871). Tylor believed that seemingly irrational customs (custom) and beliefs, such as peasant superstitions (superstition), were vestiges of earlier rational practices. He distinguished between continuing customs that maintained their function or meaning and those that had both lost their utility and were poorly integrated with the rest of culture. The latter he termed survivals. Tylor later expanded the notion of survivals to include material culture. Among other examples he invoked men's formal wear, specifically the styling of the tailcoat, as an example in which vestiges of a past item—in this case the greatcoat, with its waist-length front and split tail for ease in riding horses—had survived into the present.
