Raisson's Theory Vs Evolution Theory

Depression and Evolution by Christopher He Most of us associate the word “depression” with sadness, loneliness, secludedness, and suicide. But it seems some scientists are trying to sway the pendulum the other way, looking at depression more positively than negatively. How could you make a disease that is defined in the DSM V by unproductiveness, feelings of guilt and worthlessness, and even thoughts of suicide into something good?

Scientists have created almost a dozen theories explaining the possible benefits of depression. One theory, developed by Dr. Andrew Miller and Dr. Charles Raison, claims that people who are depressed have an over-activation of the immune system which leads to inflammation, even when they are not affected by
Evolution, at it’s core, is just a change. It is simply a change in the genetic material of a population. Many people, although they understand this, think about evolution a little differently. They think of it as a filter that removes all bad traits and only leaves good ones. If we continue down that path until we reach its end, we will eventually arrive at a perfect being, that will survive forever and won’t change, because it doesn’t need to. To the contrary, evolution is a constant change. As the environment changes, a population will change accordingly. Also, as we have all been taught, everything has pros and cons. Traits or adaptations are no exception. No adaptations are completely good and none are completely bad. Take a fish’s gills for example. Gills are a great adaptation for fish. If fish did not have gills, they couldn’t get the oxygen to live. But say, suddenly, all of the water on earth dried up. Then gills would just as suddenly turn into a terrible adaptation. This case is a little unrealistic, but it shows just how wrong it is to think of evolution so
It seems impossible that the mere possibility of a positive side to depression could defeat death. That is the argument of many skeptical psychologists. Richard A. Friedman, who often treats depressed patients says, “But unlike ordinary sadness, the natural course of depression can be devastating and lethal. And while sadness is useful, clinical depression signals a failure to adapt to stress or loss, because it impairs a person’s ability to solve the very dilemmas that triggered it.” Psychologists will continue to classify major depressive disorder as a mental disease and will continue to treat it like one. Though, it seems we cannot ignore the possibility of depression having useful
