The profusion of skin colors and physical characteristics of different humans is due to adaptation to diverse climates and other living conditions as humans spread throughout the world. This is due to the process of evolution, where genetic mutations and natural selection result in variations in physical traits that are advantageous for survival in different environments. Pure races do not exist, as humans are too genetically diverse to be categorized into distinct races, and the emergence of dominant groups in the last three centuries has no direct influence on physical characteristics. Biology is also a factor, but it is not the sole explanation for the range of physical diversity among humans.
