Theory of Natural Selection


Natural selection is the process by which heritable traits that makes it more likely for an organism to survive and successfully reproduce, become more common in a population over successive generations. It is a key mechanism of evolution (Wikipedia).


That is just the point raised by Charles Darwin’s Theory of Evolution. It held a certain premise that all life came from similar ancestors. The general theory of Darwin believes the development of life from a non-life and stresses a purely naturalistic “descent with modification.” And he claims that this whole process of evolution is done gradually. As he wrote: “Natural selection acts only by taking advantage of slight successive variations; she can never take a great and sudden leap, but must advance by short and sure, though slow steps.” And concludes that “If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.

Michael Behe on the other hand has a different view about Darwin’s theory which contradicts all of if through an irreducibly complex system with the use of bacterial flagellum. This model has basically three parts: paddle, rotor, and a motor. It raises the point that the complexity of the organelles in our body cannot be created gradually. A flagella or cilia is likened to the bacterial flagellum’s mechanism—multiple components are required to make it work, and if any of these parts are missing, then the mechanism won’t work at all. It paves way to the unexplainable evolution of DNA.

The pattern of the design implies that the root of the existence of human life is yet to be learned. Darwin’s theory is not yet fully grasp by some of us and still, things were vague. The biochemist in the film (Natural Selection) became open to the possibilities that a transcendental being is somewhat involved in the complexity of our human life. Although the film did not entirely say that there is a transcendental being out there, it is implied that there might be Intelligent Designer who exists in our midst. And since there are things that science has not answered in terms of our evolutionary trail yet, biochemist are somehow open to the idea of a transcendental reality.

But are we willing to be consumed in to this reality—existence of God—in the midst of the scientists’ uncertainty and strong belief that we are not created by the Divine being?
