"We analyze the average sonority of basic words of nearly three-quarters of the world’s languages, and confirm a positive correlation between sonority and local temperature. Our findings suggest that lower temperatures, over the course of many centuries, lead to decreased sonority. Our research provides further evidence that climate plays a role in shaping the evolution of human languages."
