The origins of language. THE SOCIAL INTERACTION SOURCE. Language arose out of the rhythmical grunts of people working together, involved in physical effort that has to be coordinated (yo-he-ho theory). Early humans may have developed a set of grunts, groans and curses used when lifting and carrying trees/mammoths. Makes sense as early humans must have lived in groups, which require some form of organization and hence communication to maintain development of language placed in a social context. THE PHYSICAL ADAPTATION SOURCE. Physical features that distinguish humans from other creatures may have supported speech production. Evolutionary development resulted in partial adaptions making speech possible for early humans. • Teeth. • Lips. • Mouth. • Tongue. • Larynx. • Pharynx.
