Origin of Language - Communication, Speech and Language

Communication, Speech and Language

A distinction can be drawn between speech and language. Language is not necessarily spoken: it might alternatively be written or signed. Speech is one among a number of different methods of encoding and transmitting linguistic information, albeit arguably the most natural one.

Some scholars view language as initially a cognitive development, its 'externalisaton' to serve communicative purposes occurring later in human evolution. According to one such school of thought, the key feature distinguishing human language is recursion. – in this context, the iterative embedding of phrases within phrases. Other scholars – notably Daniel Everett – deny that recursion is universal, citing certain languages (e.g. Pirahã) which allegedly lack this feature.

The ability to ask questions is considered by some to distinguish language from nonhuman systems of communication. Some captive primates (notably bonobos and chimpanzees), having learned to use rudimentary signing to communicate with their human trainers, proved able to respond correctly to complex questions and requests. Yet they failed to ask even the simplest questions themselves. Conversely, human children are able to ask their first questions (using only question intonation) at the babbling period of their development, long before they start using syntactic structures. Although babies from different cultures acquire native languages from their social environment, all languages of the world without exception – tonal, non-tonal, intonational and accented – use similar rising "question intonation" for yes-no questions. This fact is a strong proof of the universality of question intonation.
