I believe that Stephen Gould and Elizabeth Vrba were correct in proposing exaptation as a missing term in evolutionary biology. I want to make a distinction between adaptation and exaptation here. Again it is about mechanistic differences. An exaptation can be viewed as the acquisition of a new and useful function once the novelty has spread and once the environment has changed.

Oh great, a Boulderite. For those of you that are not familiar with Boulder it is a sort of ultra liberal oasis in the midst of a mostly moderate state. Home to all sorts of elitest snobs. To be fair, they do a good job of protecting the environment with all those growth restrictions. It is only a coincidence that those same restrictions drive the property values up so high that only the well-heeled can afford to live there. A cynic might say that Boulderites are happy to champion the cause of the poor and downtrodden just as long as they don't have to live with them.
