Darwin and Aristotle

In class today we talked about self caused motion and how it might apply to the laws of nature. I started thinking about how Aristotles views might apply to the laws of evolution. Although our current modern view of evolution is one of incidental motion, I think that the ABC formula of self centered motion may work to explain evolution just as well as incidental motion would. In this instance I see the law of survival of the fittest as the unmoved mover(A). This law has remained a constant since life first began on earth. The law itself doesnt move or change, but it causes evolution (the B) to move, which in turn causes the evolved beings (C) to change within the context of time. I think this is a pretty good example of what aristotle was talking about, and it demonstrates that nature does in fact have its own desires. All natural things have an innate desire to survive, and this drives the process of evolution, which is both being moved (by survival of the fittest) and is moving evolved forms of organisms. I am not a physics major but I am sure that this model would fit other natural laws as well, like gravity, newtons laws, ect. Can anyone else think of other examples that might illustrate how self caused motion is at work in other areas of nature.
