The environment (hot/cold, wet/dry, etc) can favour certain body types so that people in cold countries (before the mixing of peoples in the modern world) tended to be more bulky than those of hot countries. Inuits have a better periferal circulatory sytem to keep their hands and feet warm. An early response to environmentl pressure led to humans living in grasslands. Waking upright on two legs saved energy (about the same as if found in two Oreo cookies a year). This was enough of an edge to make upright walkers more likely to survive than "on all fours walkers.Similarly food supply changes people. In the case of milk the ability to digest milk appeared about 10,000 years ago in Africa and Europe. Apparently milk was an available food and those who couldn't eat it died. No one is use of the more recent mutaion of blue eye colour. The newest mutation seems to be AIDS resistance in response to the AIDS epidemic in some parts of the world.
