When a whale beaches itself, couldn't it be just trying to evolve?

Why do the animal rights groups always end up where there are beached whales, trying and force them back into the water? Why dont they just let the whales lay there and go through the process of evolution? Could it be that the whale is just attempting to evolve into a land mammal. Why is it getting forced back into the water? Why wouldnt the animal rights groups just let the whale lay there so it can have a chance to evolve? Couldnt the whale be trying to grow legs or lungs or something? How will it ever grow legs, or even lungs for that matter, if the animal rights groups keep pushing every whale back in the water? Seems to me that those who subscribe to the evolution theory are being hypocrites to theier doctrine by trying to prevent the process from taking place because they know that the whale, and every other whale for that matter would end up dying if it is left out of the water too long. But how could the whale ever evolve, if all of the whales that beach themselves, or ever have beached themselves, end up dying? Shouldnt the animal rights groups just let nature take it course so we can see what the whale would become if given the chance to evolve? Is it not true that every whale that ever beaches itself, or ever has beached itself, becomes just a steaming pile of blubber on the beach? And since that's what happens, isnt that why the evolutionists try and push the whale back in the water? So how could evoltion ever have even taken place if every animal that attempted to leave its habitat, for a new one, ends up dying?
