Alright: since you can't actually point to an example and say "well, it's been tried, but it didn't work", then I'll point you toward examples of this actually having been done: Look at all of the breeds of dogs that have been created by man by selective breeding, where a specific desirable trait (similar to the ability to get food in every deeper water) has been breed into a dog.

Sorry cannot resist....
Got to love how you credit 'man' to creation of a 'breed' and totally ignore who created the DOG!
Breed me a dog that changes into something that isn't dog like. Breed me a dog until not only is it unrecognizable as such. Breed me dog that flies. Breed me a dog with gills that can breathe underwater. I'm surprised nobody has done these yet. A flying dog would make it much easier to hunt ducks. The point being that dog breeds are primarily cosmetic differences in size and shape within the same kind, not major leaps in function.
