The evolutionary purpose of depression and anxiety

We live in an age of anxiety with rates of depression skyrocketing all over the world. But there may be an evolutionary purpose for all this suffering says Dr Randolph Nesse. It’s an idea based on his years of work in the areas of psychiatry and evolution.  He says natural selection would have gotten rid of autism, schizophrenia, and manic-depressive illness, so they are written in our genes for a reason.
