Abstract: This paper speculates on a new form of evolution that suggests that the way man evolves is essentially different from that of all other forms of animals or plants. It is postulated that evolution has proceeded through three phases, and that mankind is moving into phase IV with additional phases possible. Phase I consists of the systematic changes seen in the origin of the universe through physico-chemical evolution. Phase II is that in which living organisms appear and evolve in form and function. When mammals reached a certain complexity, Phase III became possible. In Phase III culture replaces natural selection as the adaptive mechanism. The author further postulates that mankind is moving into Phase IV in which it is argued selfconscious cooperative behavior is necessary for future adaptation and development.
