I seem to recall that an experiment was done where blind fish from two separate caves were crossed and this produced fish with normal eyes.

There is a link to a story on the Science News page above.The gist is: they created hybrids out of four cave fish populations and found that some hybrid crosses produced 40% sighted offspring. Their conclusion was that evolution has many ways of achieving eye loss: some populations deficiencies may be compensated for by remaining strengths in others.
