Evolution is supposed to inch forward over eons, but sometimes, at least in the case of a little fish called the threespine stickleback, the process can go in relative warp-speed reverse, according to a new study. The adaptation coincides with the '60s cleanup of toxic pollution in Seattle's Lake Washington.
