<span>Since we are not able to get energy directly from the food we eat, a particular process needs to take place that converts molecules to Adenosine triphosphate, also known as ATP. This requires that the food first be broken down by being digested. As digestion takes place, the body uses the small molecules to make ATP.</span>
I believe it is a combination of polygenic inheritance and environmental factors. Several genes control the height in humans, giving an overall normal distribution. Environmental factors on the other hand such as nutrition smooth out the curve. It is therefore important to note that Human height is a quantitative, or metric trait, that is, a characteristic that is measured in quantity, and is controlled by multiple genes and environmental factors.
