I have argued before that humanity has reached a pinnacle of evolution and will not continue to evolve. (See: Human Evolutionary Dead-End)
It occurs to me, though, that we are in fact heading in the opposite direction. We are going to de-evolve, at least in the sense that our negative genetic characteristics will eventually dominate our positive ones. Our survivability as a species will taper off and decline. We are heading for a slow extinction brought on by technology and science.
