By now most accept the magic of [[evolution by natural selection]]. This really ''is'' magic: a comprehensive account of the origin of life — indeed, the sum of all organic “creation”, as it were — can be [[Reductionism|reduced]] to a mindless, repetitive process that we can state in a short plain English sentence.

The economy of ''design'' is this process is staggering. The economy of ''effort'' in its ''execution'' is not.

Evolution is ''tremendously'' ''wasteful''. Not just in how it does adapt, but in how much of the time it does not. The chain of adaptations from amino acids to Lennon and McCartney may have billions of links in it, but that is doddle compared with the number of adaptations over that time ''didn’t'' get anywhere — that arced off into one of design space’s gazillion dead ends and forlornly fizzled out. For every serendipitous mutation ''there are millions and millions of duds''.

Evolution isn’t directed — that is its very super-power — so it fumbles blindly around, fizzing and sparking, and its power is that vanishingly small proportion of mutations that ''accidentally do something useful''. Evolution is a random, [[stochastic]] process. It depends on aeons of time and burns unimaginable resources. Evolution solves problems by ''brute force''.   
The chain of adaptations from amino acids to Lennon & McCartney may have billions of links in it, but that is a model of parsimony compared with the number of adaptations over that time ''didn’t'' go anywhere — that arced off into one of [[design space]]’s gazillion dead ends and forlornly fizzled out. For every serendipitous mutation ''there are millions and millions of duds''.

Even though it came about through an evolutionary process, “natural” mammalian intelligence, whose apogee is ''homo sapiens'', isn’t like that. It ''is'' directed. We can narratise and hypothesise, remember,  learn, and rule out plainly stupid  ideas without having to go through the motions of trying them.<ref>I know, I know. Hold your letters.</ref>
