Document Summary
Smaller change, shift in gene frequency to one form. The extremes are picked off due to low health and ability to be birthed. Short term not inherited due to your adjustment to mental stresses. They have more exposure to high uv. Dramatic effect on physiology because of the role of pressure in exchange of air. Can acclimatize to it, develop different types of breathing a deeper faster breath, higher heart rate and blood rate, alkaline blood stream. Increased lung size (large chest), more powerful heart muscle (developmental changes, permanent) reduced fertility, Slower maturation rate, also live longer due to disparate populations among high altitude in addition to active lifestyle that accompanies the high altitude lifestyle. Other animals like the yak have adapted.
