What is an example of survival of the fittest?
the blind fish have lost genes needed to make eye tissues. The blind fish can run into rocks without damage to the eye tissue because the outer vulnerable eye tissue is no longer there. The blind fish are most fit to live in the environment of total darkness. These are just two examples of survival of the fittest .
