A species of fly was kept in total dark conditions for 57 years. When the species was again reviewed it was noticed that the fly had started to lose its sight ( sight is no longer needed in total darkness ) but started to gain traits that would benefit it in total darkness.

We found that Dark-fly exhibited higher fecundity in dark than in light conditions, indicating that Dark-fly possesses some traits advantageous in darkness.

Evolution in action?

For a good basic intro to the evidence, prof Dawkins has a great non overly techy book out, well worth a read: (and tbh, there is no-one better than RD on evolutionary scince books, the guy is pure genious :) )
