It's recognized that fear is a primal emotion and may actually come from evolution. Some fears are ancient emotions passed on from generation to generation. Psychologists have identified this condition by testing it in laboratories. They've found as a species, we have innate fears, such as fear of certain animals, insects, or even heights. This condition has been defined as a lack of preparedness. It's theorized that in the past, those who were prepared were more likely to survive than those who were not, a form of human selection. Today, by diversion, we've made fear a fantasy, but it's a reality, and we'll feel it.
