Mutations accomplish so much. But prof, the best mutations accomplish the least and therefore damage the least. Those that accomplish the most, kill outright, for they damage in such big ways. Thus we see that mutations are the chief source of evolution. But prof, new genetic information would be needed for one species to evolve into another.
Every mutational change is a step in the right direction.
But prof, organic change requires positive networking changes, and these mutations could never accomplish. The greatest evidence that mutations can produce changes is to be found in fruit fly research. But prof, all the changes were damaging, and none changed fruit flies into something else. They remained fruit flies. Well, species change is supposed to be the basis of evolution.
