Despite the few examples of beneficial genetic mutations it is unrealistic to assume that this information produced through changing already existing DNA would then be acted on again by another related mutation to build increasingly dissimilar and complex structures than what was there previously. This is to say that mutations are not a reasonable means of producing cascading morphological change from one kind of animal to another. | Despite the few examples of beneficial genetic mutations it is unrealistic to assume that this information produced through changing already existing DNA would then be acted on again by another related mutation to build increasingly dissimilar and complex structures than what was there previously.

Obviously mutations can indeed cause dramatic | Obviously mutations can indeed cause dramatic phenotype change from environmental pressures. Many experiments have been performed on fruit flies (Drosophila) where poisons and radiation induced mutations. However, the problem is that they are always deleterious. The Drosophila experiments showed an extra pair of wings on a fly, but these were a hindrance to flying because there are no accompanying muscles. Therefore, these flies would be eliminated by natural selection. Even in the case of mutations which can change the amount of DNA possessed by an organism, an increase in the amount of DNA does not result in increased function. Biophysicist Dr. [[Lee Spetner]] in his book, ''[http://store.nwcreation.net/notbychshmot.html Not by Chance: Shattering the Modern Theory of Evolution]'', analyzed examples of mutational changes that evolutionists claimed were increases in information, and demonstrated that they were actually examples of loss of specificity, meaning loss of information. | ||
