Article reads: Natural selection is driven by genetic mutations, and we usually can predict and understand the short-term fate of a mutation. If a mutation makes the organism more fit, it tends to last through the years; if the mutation is harmful, it usually dies off with its host organism. Evolutionary biologists, however, do not have such a complete understanding of the long-term consequences of mutations. Is it possible that what is good now may be not-so-good later?

Yet we are told that evolution coopts prior function to derive new function, and this is the only way to get beyond Behe’s “irreducible complexity.” So our very few 25,000 genes were coopted from our far distant ancestors that were clueless of present day humanity: so what had been good is very good today. It is cooption, not the drive to abundance, that is the hallmark of evolution. Yet it is nice to have abundance from which to coopt and optimize.
