I learned a new word today: "exaptation". It was apparently coined by S.J. Gould in 1991, and is widely used in science:. "The utilization of a structure or feature for a function other than that for which it was
developed through natural selection. ex- + (ad)aptation.ex·apted..."
I found many sites about it on Internet. It might be fun to think of ways to use it. Some of the biology uses we all know. Perhaps there others we could think of.
