In the end, it may come with encoded new behaviors that which are required for a new physiological function and thereby discourse the selective advantage.

Nutrigenomics involves the characterization of gene products and the physiological function and interactions of these products.

If the acids remained in the body, they would accumulate in areas of low blood flow (like joints), thereby obstructing normal physiological function.

Combined, these changes result in decreased efficiency and resiliency of physiological function.

A decrease in estrogen levels can lead to osteoporosis, cognitive disorders, and can affect many important genes related to normal physiological function.
