Mutation For modern evolutionary theory, the question of mutation is of great importance. If mutations had not occurred, evolution would not have been possible. Therefore, we must study the question of mutations and see if they do take place, as evolutionists claim. First of all, there is no doubt that mutations can and do occur. Secondly, there is no doubt that any change in the gene is always a change for the worse. This was to be expected. Genes are complex and surprising, and any major change in them leads to their less effective functioning. This is what geneticists have learned after seventy years of intense experimentation. During this time, they caused thousands of mutations in different organisms, but they never managed to get any mutations that would have a convincing effect on the body. Indeed, it is now generally accepted that mutations in vivo are so rare and so often harmful that when they occur, they have no significance for the genetics of any population of living b
