Intervening in the events of the world, we take their information out of the world, and by processing it we finally know what it is. This information processing is the common basic scheme itself everywhere we are aware of things or events. If we look back over the brief history of the synthetic theory of evolution with the scheme, we can realize that the theory has very different characteristics from Newtonian mechanics. First of all, the theory has many different 'forces' of causing evolution and some force is not consistent with others. This means the theory should be inconsistent. This seemingly serious trouble is recovered by thinking epistemologically things as information. Then each force, for example natural selection or random genetic drift, has different informational framework and so they cannot be compared directly. This kind of philosophical interpretation has been required reluctantly since the great success of Newtonian mechanics, because the classical mechanics has been interpreted realistically. This informational interpretation might imply the bad relativism. If each theory or force has its own intervening way and the following particular kind of information, inconsistency of forces disappears, but we must admit that the synthetic theory of evolution is not the unified theory, but only the collection of theories.
