Richard W. Stevens points out that a bird does not fly just because it has wings; it needs a Explanations of the evolution of flight do not account for that.“flight” program in its brain:
Somehow, when we think about evolution, the problem of hardware–software coordination is ignored. Take, for example, the neo-Darwinian claim that modern birds evolved from reptile-like dinosaurs. Discussions of dinosaur-to-bird evolution talk about the hardware changes: scales became feathers, legs became wings, cold-blooded (exothermic) physiology became warm-blooded (endothermic) physiology, tooth-filled mouths became beaks, and so on. All of these monumental changes in hardware present enormous operational challenges that incremental mutations somehow solved over millions of years. But totally missing is any account of the evolution of the necessary software.
Assume for the moment that unguided mutation could actually modify a reptile and install the wing apparatus, including all the muscles and feathers. For the early stubby proto-wing to give the modified reptile the “survival advantage” necessary to win in natural selection, the reptile must know how to use the proto-wing. A reptile with proto-wings instead of legs is like a human with roller skates instead of feet. The reptile must have the biological software to operate the proto-wings successfully. Whatever software the legged reptile had, it won’t operate a proto-wing. The stubby-winged reptile is worse off than his legged brothers and sisters, not better, and won’t win the natural selection prize.Richard W.

He goes on to explain that, to understand the problem created by ambitious claims for random evolution, we need to consider the difference between the hardware and the software of life.
