Innate behaviour

Innate Behaviour refers to the actions of an animal, or human, that aren't quite described in genes, but they are expressed without prior experience through watching another individual. They are the responses, to a stimulus, that are quickly figured out through an attempt. Since nerves and pathways in the brain are connected through certain regions, then a response which stimulates the area of the original stimulus (desire) through another body region or organ, will be remembered. The Innate behavior is the use of these connected areas to solve the stimulus response problem. Taste or smell can stimulate hunger. These areas are connected in that eating, causing tasting, together solve the hunger issue. Since just smelling a food causes more hunger, the next closest cause of hunger is probably the pathway to the fix.
