Many factors contribute to the idea of gradual speciation, but all fall under the same theory of evolution. Webster defines evolution as "the theory that groups of organisms change drastically and smoothly with passage of time, mainly as a result of natural selection or chance, so that descendants differ morphologically and physiologically from their ancestors." With regard to the theory, one must consider the facts that are certain to refute the concept. Disproving the theory of Evolution has nothing to do with the validity of creationism (a god created the earth) or the Bible, but rests solely on the authenticity of the evidence the theory puts forth. To understand evolution, a non-believer must outline what he/she would expect from the theory, listen to the evidence, then offer an explanation of why sufficient evidence is not produced and try to interpret why believers stay with the theory.
             In order to convince one of the validity of the theory, the listener must know what to expect for the theory to "be true". Evolution violates what we as people think about the world. Naturally, such things as carcasses, chemical bonds, and sewing seams break down over periods of time. The difficulty comes, however, when one is to throw out the idea that things come together so smoothly as they break down. Evolution derives from the concept that human beings and other animals came from single-celled organisms. The same thing is seen in a car. The engine needs a fuel injector, pistons, gas tank, and many other parts to work correctly. But if one part isn't there, the engine doesn't work. One must expect the theory to provide that all of the parts of humans that derived from the single-celled organism came together smoothly. This trait is shown a couple of times in nature such as in a snowflake. A snowflake comes together by the extraordinary laws of thermodynamics, so!
