It's ability to survive on land is passed on to it's children because sharks breed through meiosis which allows variation to occur. The children of the shark who can survive on land longer keep increasing the time they can survive for until they could live comfortably on land. If they stayed on land for long periods, their offspring over many generations until it could develop legs to capture more food. Now this is a very unlikely scenario and would take maybe millions of years to happen but this is basically how evolution works.

So conceivably, you could put a million fish on the beach and expect at least one of them to survive, and its offspring to do the same. Gee, why hasn't any scientist ever tried this?
Evolution seems so simple to prove, and yet no one ever has.
