Well, of course they're using the idea of evolution! Other than with the elder dragons, they seem to try to be as realistic as possible... in fact, if you look at that Animal Planet show, "Dragons: A Fantasy Made Real," you'll see that it's even scientifically possible that an animal could breathe fire, there just aren't any real animals that we know of that can do it.
