Language Development and Geography

The evolution of language is a puzzle that has intrigued and confounded linguists for years. The path languages take as they grow and evolve around the world brings new insights into the history of the human race and can answer some very important questions about how we evolved. New linguistics research has just come out which explores the relationship between location and language development, shedding light onto some previously unexplored territory.

Researchers around the world are pooling their resources and knowledge to find out how climate affects language development. They are looking into how climate, such as rainforests or deserts, affect what languages are spoken there and what those languages sound like. For instance, languages that develop in hot, humid locations are more likely to utilize consonants less, while languages that exist in a more temperate, flat landscape may be more consonant-heavy.

English is a language that is full of consonants and high frequency noises. These noises are less likely to be heard in places that have a lot of trees or are mountainous and windy. In these areas sounds bounce off the mountains and trees or will be carried away by the wind, so what the other person hears can be very different from what was actually said.

Vowels like “e” or “a” are more easily heard in dense rainforests or through rocky hills. Additionally, in hot climates vowels are better understood because warm air can disrupt some consonants and higher frequency sounds. The linguists’ theories, therefore, ride on the idea that language is developing in certain climates to make it easier to understand and communicate with one another by the people who live there.

The researchers are basing this line of inquiry into human language development on similar studies that have been conducted on birds. Scientists have researched the way different species of birds sing in different climates and found that birds living in rain forests sing songs with fewer audible consonants than their counterparts in more flat or open places.

This linguistic theory hasn’t been entirely validated, however. Other influences for language development include the close relationship between people groups who speak the same (or similar) languages and the geographical path language has taken around the world over thousands of years. For instance, the Hawaiian language developed in a hot and lush climate, as did the Maori language in New Zealand; both these languages are also related to an older Eastern Polynesian language.

Nature certainly has a major effect on language development in humans, but the extent of this influence is still yet to be discovered in its entirety. Linguists will continue to work on the origin and evolution of the world’s languages as they relate to people groups, geography, and climate.
