If these theories fail, then additional hypotheses have to be proposed. During the process of the testing these hypothesis, experimentalists will find evidence based that will enable to fine tuning of the hypothesis, and the process carries on. Indeed, most of quantum theory is hinged on the Uncertainty principle put forward by Werner Heisenberg. What apt that it be named the Uncertainty principle. Eventually, one hopes that some consensus will come between those that support graduated equilibrium vs. phyletic gradualism in terms of evolution of species. Or a new theory will develop and come to the fore, if new fossil evidence comes to light. But that does not mean that we subscribe to the watchmaker theory. William Paley, an eighteenth century moral theorist, philosopher and religious conservative, was perhaps the first to propose a formal explanation for creationism, and made perhaps the first foray into Intelligent Design theory. Paley averred that a human being or other organisms on earth could be likened to a watch found in the desert. (VictorianWeb 2008) This watch had to be made by a creator and placed among the grains of sand. It was inconceivable that the winds and the sands had some one conspired to evolve into a working time piece over time.

The best debunking of Paley's ideation comes from the noted science fiction writer Isaac Asimov. Writing in one of the essays, in his collection titled "The Roving Mind," Asimov proposes a counter argument. He avers that most of us drive automobiles, but only few of have an understanding of the internal combustion engine and the complicated engineering systems that make a car go. But just because we don't know what makes a car run, does not mean that the car does not contain an engine. He criticizes would be creationists by adding that a creationist would believe that a team of horses under the hood is what makes the car run. (Asimov 1983) strongly believe that evolution should be taught in schools as the current primary theory of evolution. But just as with all theories, the caveats, gaps, lack of experimental evidences should also be taught. It is a theory that provides the best explanation of speciation, but this does not mean that all scientific inquiry into the matter should cease. At the same time creationism and Intelligent Design merit a very brief mention, if nothing else to give students a world view of the different schools of thoughts out there. Intelligent Design is like an Indirect proof in Mathematics which starts out by believing the...

And this is not a slight against those who believe that God created earth, based solely on solid faith. But to put a pseudo-scientific notion of Intelligent Design as an explanation for how we evolved is, and here I agree with the noted blogger Professor Glen Reynolds of Instapundit.com is "pernicious twaddle."
