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 … Read more Mutations cannot explain Evolution
