No. What happens is that any mutation that has a tendency to try to come up on the land has to compete with the creatures already there, and will be unsuccessful, so it won't reproduce. In the past, this would have been a successful mutation. Presently, it would be a failed one.

Ooooooooooooh, now I get it. By the way...how many of these mutations have you or anyone else observed trying to "come up on the land"??? I'm sure this has been documented many times since we all know that evolution is fact and not just an athiest's lame excuse for the obvious. ;-)

That's kind of a stupid question. We've already told you that it happened hundreds of millions of years ago, and took place over a long period of time. How would anyone have seen it?
