You have a slight problem. Asserting the generation of a whole new animal "with new organs, a new basic plan," etc, all at once, describes creationism, not evolution.
Take flying birds for example; suppose you aren't one, and you want to become one. You'll need a baker's dozen highly specialized systems, including wings, flight feathers, a specialized light bone structure, specialized flow-through design heart and lungs, specialized tail, specialized general balance parameters etc.
Ooops. More problems. Despite your arm waving (non) calculations, all those features are now known in pre-avian reptiles (dinosaurs).
For instance, as to "a specialized light bone structure, specialized flow-through design heart and lungs," I posted THIS INFORMATION just a couple weeks ago:
Not only did many dinosaurs have hollow bones, for a genus described last year, there is specific evidence that these bones possessed the same special respiratory function they (otherwise uniquely) do in birds! Full article is online at the link:Sereno PC, Martinez RN, Wilson JA, Varricchio DJ, Alcober OA, et al. (2008) Evidence for Avian Intrathoracic Air Sacs in a New Predatory Dinosaur from Argentina. PLoS ONE 3(9): e3303.
In this YouTube video you can see one of the authors holding one of the hollow bones.
The following figure from the article shows some of the pneumatopores (where the air sacs entered the bones) in the fossils from this dinosaur, which btw is named Aerosteon, Greek for "air bone":
So, we find a very specialized adaptation, otherwise utterly unique to birds, in a group of dinosaurs which were previously identified (about 150 years ago, btw) as closest to modern birds. Coincidence? For creationists, I suppose it has to be.
Which side is it which is talking about miracles??
