EARTH Magazine: Of Temperature and Tone - Has Climate Shaped Human Languages

EARTH Magazine

From EARTH Magazine, 04/23/2015  --  We have known for a long time that an environment can influence the vocalizations of animals. Scientists at the Max Plank Institute for Psycholinguistics wanted to see if a similar correlation between environment and language could be demonstrated for humans.

In a new study, described this month in EARTH Magazine, the geography of tonal languages - those using variations in pitch to distinguish distinct meanings for the same word - was plotted relative to non-tonal languages. The results revealed a potential correlation between warmer, more humid climates and tonal language. This hypothesis, presented in the Proceedings of the National Academy of Sciences, would suggest that a cooler, drier climate could inhibit evolution of a more complex tonal language. 

While natural analogues in the animal kingdom exist, not all linguists are convinced this correlation is specifically related to climatic variations.
