The primary explanation given for the relatively rapid increase in average human height in recent years is improved nutrition, health care and living standards. Many argue that evolution plays a very small role in the increase of human height, as evinced by the comparative shortness of people in developing countries. However, differences in climate also seem to have an impact on height, since peoples originating in colder climates tend to be shorter and broader, and those from hot climates are taller and thinner.
