Mutations are defined as breaks or replacements taking place in the DNA molecule, which is found in the nuclei of the cells of a living organism and which contains all its genetic information. These breaks or replacements are the result of external effects such as radiation or chemical action. Every mutation is an "accident," and either damages the nucleotides making up the DNA or changes their locations. Most of the time, they cause so much damage and modification that the cell cannot repair them.
Mutation, which evolutionists frequently hide behind, is not a magic wand that transforms living organisms into a more advanced and perfect form. The direct effect of mutations is harmful. The changes effected by mutations can only be like those experienced by people in Hiroshima, Nagasaki, and Chernobyl: that is, death, disability, and freaks of nature…
The reason for this is very simple: DNA has a very complex structure, and random effects can only damage it. Biologist B. G. Ranganathan states:
First, genuine mutations are very rare in nature. Secondly, most mutations are harmful since they are random, rather than orderly changes in the structure of genes; any random change in a highly ordered system will be for the worse, not for the better. For example, if an earthquake were to shake a highly ordered structure such as a building, there would be a random change in the framework of the building, which, in all probability, would not be an improvement.(B. G. Ranganathan, Origins?, Pennsylvania: The Banner Of Truth Trust, 1988)
Not surprisingly, no useful mutation has been so far observed. All mutations have proved to be harmful. The evolutionist scientist Warren Weaver comments on the report prepared by the Committee on Genetic Effects of Atomic Radiation, which had been formed to investigate mutations that might have been caused by the nuclear weapons used in the Second World War:
Many will be puzzled about the statement that practically all known mutant genes are harmful. For mutations are a necessary part of the process of evolution. How can a good effect-evolution to higher forms of life-result from mutations practically all of which are harmful?(Warren Weaver et al., "Genetic Effects of Atomic Radiation", Science, vol. 123, June 29, 1956, p. 1159.)
