Document Summary
Individual level during critical period of growth and development. Capacity is inherited but change is not inherited. E. g. altitude adaptation; if you have a genetic template saying. This is how big your bones will be , but do not get the proper nutrition, then they will not be able to get to the potential. If the bones don"t do anything they think they don"t have to be strong. If the bones are used a lot (exercise) they think the need to be big and strong. (before puberty is the only time to build up bone) Stresses: hypoxia, intense solar radiation, cold, low humidity, wind, reduced nutritional base, and rough terrain. They have a shorter stature, but large chest circumference to compensate for low oxygen at altitude. Biogeographic rules of body shape and temperature adaptation. Average body size in cold climate populations is larger than body size in warm climate populations.
