A number of people have emailed me a link to this story about “reverse evolution” in sticklebacks residing in Lake Washington. The basic story is that as Lake Washington was cleaned of its pollution sticklebacks went from being low plated to being completely plated. Partially, this was a response to heavier predation caused by increased clarity of the water.
