Humans exhibit physical variation in appearance due to a combination of genetic diversity, environmental factors, and evolutionary adaptation. Genetic variations accumulated over generations, along with environmental influences such as diet and climate, contribute to the wide range of physical characteristics seen in human populations. Additionally, natural selection and genetic drift have played roles in shaping human diversity as different populations adapted to diverse environments.
