Language evolved as conversation, each baby learns it in conversation and most of our use of it each day is in conversations. Exchanges, taking turns, is the essence of language. A recent paper by S. Levinson in Trends in Cognitive Sciences, "Turn-taking in Human Communication – Origins and Implications for Language Processing", looks at the complications of turn-taking. The world's languages vary in almost all levels of organization but there is a striking similarity in exchanges – rapid turns of short phrases or clauses within single sound envelopes. There are few long gaps or much overlapping speech during the changes of speaker. Not only is a standard turn-taking universal in human cultures but it is found in all types of primates and it is learned by babies before any language is
