A very important factor to this principle, is evolution. As the theory of evolution has been accepted, it is agreed that it works through genetics and inheritance, thus accepting too that behavior follows the same pattern of evolution.
 * 1. Behavior can be inherited as its genetically based **

 * STUDY:** Bouchard et al. (1990) - Twins (Nature vs Nurture)

Following the theory of evolution, it is said that humans derive from animals, thus a resemblance between both exists. As some anatomy and behavior is shared between both species, research done on animals may at times give us the required knowledge to hypothesize what would happen to humans on the same situation.
 * 2. Animal research can give important insight on human behavior **

Rosenweig & Bennet (1972) - Thickness of Cortex
 * STUDY:** Heath & Olds (1950's) - Dopamine Addiction

There is a relationship between behavior and physiology, as emotions and behavior are the result of anatomy and physiology of the nervous and endocrine system. The idea in BLOA is; therefore, to find a link between a biological factor such as a hormone, and a specific behavior.
 * 3. There is a biological correlation of behavior **
