The climate maps have been combined with an additional map which divides the world into 17 language families with a good distribution across continents; moreover, continental boundaries were used as the final characteristic in developing regions with the idea that geographical barriers between continents such as mountains, oceans, etc., create barriers to migration causing cultures to remain in place and develop new vernacular traditions. Combining the de Dear climate map and the map derived from the Evolution of the Human Language Project and the continental map, resulted in 114 vernacular regions across 11 climate zones that contained a unique combination of language family, climate and continent. In particular, the following pictures show the vernacular areas where the climate locations object of analysis are placed.
