A lack of comprehension does not a contradictory argument make. In the sense you mean yes it is reducable. Each set of codons codes for a specific part of the body. Mutation is the direct result of specific reduction. Sometimes the end result of said mutation is death, less often an entirely new species can be generated. Variations also occur in the middle. Because you have trouble understanding a concept, does not perclude that concept from being probable. In the case of the widely accepted explanation you are without ground for arguing. For the last time ignorance is not a good motivation.
