The Clime’s Speech
21st February 2015
(Phys.org)—Human speech is not typically thought to adapt to the environment, and a standard assumption in linguistics is that sound systems are in fact immune to ecological effects. Recently, however, scientists at University of Miami and several Max Planck Institutes in Germany and The Netherlands have, in a single study, predicted that complex tone patterns should not evolve in arid climates by reviewing laryngology data on the negative effects of aridity on vocal cord movement, and – by analyzing climatic and phonological data on over 3,700 languages – found support for their prediction.
