We know from an abundance of recent research that schizophrenia is heavily genetic in origin. One would think that natural would have eliminated the genes that predispose to psychosis. A study published earlier this year in Molecular Biology and Evolution provides clues as to how the selection potential for schizophrenia may have arisen in the human brain and, in doing so, suggests possible treatment targets. It turns out that psychosis may be an unfortunate cost of having a big brain that is capable of complex cognition.

This really interesting. I wonder what other mental illnesses there are the only humans have. The scientist says there may be a connection to autism in this as well, which makes me think there may be other illnesses that we could find a link to in this.
