Mutations Mean Devolution NOT Evolution
Our tour has mentioned this several times: random mutations are harmful, they cause damage. They do not cause life to improve or gain new capabilities or functions.
Mutations are harmful. This fact is obvious, except when we are talking about evolution something happens to our thinking. For example, if mutations provided benefits, helping us to evolve and become better, wouldn't we seek ways to increase mutations? No. We know mutations are harmful so, for example, we avoid nuclear radiation. Some of us even avoid solar radiation. To much sun can cause skin cancer (mutations in the skin). And a nuclear power plant accident is a major catastrophe. We know mutations are harmful.
However, not all mutations are bad. We're talking about random mutations. The kind that supposedly result in evolution. Life has been designed to adapt, within limits, to a changing environment. We actually have preprogrammed mutations built into us.
How can we identify a preprogrammed mutation? In experiments with mice it was noticed that when placed in certain stressful conditions, the mice DNA would mutate so as to adapt the mice to the new conditions. This happened quickly, within a few generations. And it always happened in the same way. The exact same mutation would happen every time, in every mouse lineage. This is impossible for random mutations to accomplish. Geneticists realized they had discovered preprogrammed mutations.
