Yes, but part of the idea that Wills proposes is that some genes (actually exons and domains) are generally useful in the construction of proteins. Things are getting better at evolving because they have developed, through natural selection, a good set of "snap on tools" (his metaphor). They have been useful for many situations in the past and will probably be so in the future. He even says that it explains some of the startling evolutionary convergences we see in the fossil record, e.g. the mammalian and marsupialian radiations.
