Sorry, how do you think life might harness mutation? I don't see a way for that to happen. Many environmentally induced traits are actually preprogrammed into DNA, not evolved. But maybe you have some ideas on it?

Well, Darwin believed that adaptation had “inertia” such that organisms would “accelerate” toward a niche and then sort of settle into it. So that is one case in which mutation rate may not be constant.
I agree with you that Darwinian theory is not sufficient by the way.
