Environment and climate have helped shape the varied evolution of the human languages, suggested a new study by the University of New Mexico and Laboratoire Dynamique du Langage-CNRS.

The team conducted an extensive study to examine the relationship between the sound structures of a worldwide sample of human languages and climatic and ecological factors including temperature, precipitation, vegetation and geomorphology. The findings of the study shows a correlation between ecological factors and the ratio of sonorant segments, which are produced by uninterrupted airflow, to obstruent segments, which are formed by obstructing airflow, in the examined languages.

This supports the hypothesis that acoustic adaptation to the environment plays a role in the evolution of human languages. Primary researcher Ian Maddieson said, "We believe this work is by far the most extensive and careful work on a possible link between specific aspects of human languages' sound patterns and environmental factors. Our findings offer support for an application of the Acoustic Adaptation Hypothesis - which argues that species adapt their acoustic signals to optimize sound transmission in the environment they live in - to human languages." The hypothesis was first proposed by E.S. Morton in 1975 in relation to the calls of 177 bird species.

The study will be presented at the 170th Meeting of the Acoustical Society of America (ASA), being held from November 2-6, 2015, in Jacksonville.
