Try this approach to exaptations. They really smell of teleology:--http://www.sciencedaily.com/releases/2013/07/130715134424.htm-"The findings underscore the idea that traits we see now -- even complex ones, like color vision -- may have had neutral origins that sat latent for generations before spreading through populations, Wagner says."-Why keep something that is useless and 'latent' for generations. Why doesn't it disappear? Does natural selection really have any true selective capacity for parts that are just sitting around?-"From a strictly scientific perspective, the exaptation explanation does not work. For it requires that evolution is constantly getting lucky as it constructs all kinds of biological subcomponents and machines which, as luck would have it, just happen to fit together to form completely new and different machines which work wonders."-http://darwins-god.blogspot.com/2013/07/this-new-paper-on-how-innovations.html
