The inference of irreducible complexity: Criticizing and evaluating of Michael Behe's theory

For the first time, the concept of irreducible complexity was proposed by Michael Behe in order to criticize Darwin’s theory of evolution based on biochemical facts. He has defined the concept as a single system containing purposeful and interacting parts in which its components possess particular functions. Behe rejects the theory of natural evolution through explaining of biochemical reactions, in details, occurred in environment. Providing scientific evidence and methodology, as well as numerous pre-assumptions in the realm of philosophy of science, Behe demonstrates his inference concerning to irreducible complexity, and answers scientifically to the empirical and methodological objections of the critiques. He divides the life into two parts including reducible and irreducible sections. Based on his theory regarding non-irreducibility of life, Behe invalidates the theory of evolution, possessing gradual processes, in molecular level. Overall, according to various findings and researches made by Behe and the proponents of his theory, the inference of irreducible complexity is now as an inference to the best explanation suggesting appropriately a scientific approach for disclosing the life origin and exhibiting the life has been guided and designated.
