Some of the best of this work are in understanding emotions and the development of our emotional processes.   Anxiety and Fear The pure form of anxiety is that it is the experience of some sort of fear. If you think about how your body feels when you are anxious compared to when you would consider yourself fearful, you may notice a lot of similarities. But the anxiety experience may be slightly less intense. Consider anxiety as a way your body is alerting you to some sort of fear of the future, failure, or embarrassment. Evolutionary Psychology The basics of evolutionary psychology are that we all have two basic evolutionary tasks: survival and reproduction. Over thousands of years, most of our experience can now be understood as having some sort of “evolutionary advantage,” meaning that having these traits (even higher anxiety) helped us survive and/or reproduce successfully. Evolution and Emotions One of the major theories on the function of emotions is that they evolved to quickly organize all of our cognitive functions when necessary. For example, if we encounter an angry tiger, we become fearful. The experience of fear sharpens our senses, quickens our thinking, activates our fight-or-flight response, and does a variety of other things. Therefore, we don’t have to consciously get ourselves to notice the danger of the tiger. We are instantly prepared to deal with it. People who were able to do this better clearly could survive and reproduce. The same principle can be applied to anxiety. Obviously, anxiety and fear are linked, so the organizing power of anxiety is important. Additionally, the evolutionary advantage of anxiety specifically could be that worrying about danger forces people to take fewer risks, seek safety, and focus on doing things well. Clearly, this would help the basic evolutionary tasks.   Generalized Anxiety Disorder People with generalized anxiety disorder (GAD) could have a predisposition to experience greater levels of anxiety that in previous times of human history were advantageous. Essentially, GAD can be seen as an over-reaction to the fear response in modern society. As modern society has created a place for more people to be evolutionarily successful, this chronic anxiety becomes a burden and seen as an obstacle. Seeking treatment for GAD can certainly be helpful in this, but know that you are likely carrying the genes of your ancestors who found some advantage in them that allowed you to be here today.
