Evolution through natural selection depends on mutation. If we stopped all mutation, we would stop evolution too. We would be stuck in local optima, never trying to find a better global optimum. Not every new practice will work out. The bad ones will be weeded out by natural selection. But if we try to stop evolution by discouraging mutation, we will stagnate.
