The purpose of this paper is to investigate the characteristics of human constitution adapting to environment. Human constitution adapting to climate zone is basically classified into four types: The Af〈그림〉constitution adapting to warm-humid climate, the Aw〈그림〉 constitution adapting to warm-arid climate, the Dw〈그림〉 constitution adapting to cold-arid climate and the Df〈그림〉constitution adapting to cold-humid climate. The 〈그림〉constitution can be changed into a 〈그림〉constitution by adapting to cold climate or by heredity combination with the 〈그림〉constitution. The 〈그림〉constitution can be changed into a 〈그림〉constitution by adapting to warm climate or by heredity combination with the 〈그림〉constitution. The four constitution types consequently can be classified into eight types: The Af〈그림〉 constitution, the At〈그림〉 constitution, the Aw〈그림〉 constitution, the Aw〈그림〉 constitution, the Dw〈그림〉 constitution, the Dw〈그림〉 constitution, the Df〈그림〉 constitution and the Df〈그림〉 constitution. This study investigated the characteristics of fingers of people with these constitutions and confirmed that the fingers of the 〈그림〉constitution man are longer, slender and cooler than the fingers of the 〈그림〉constitution man.
