we do. the transitional species for humans was when we evolved to walk on two legs (remember lucy). if you look at the skeletons, you can definetly see the growth overtime.
as for transitional species, there are fish with legs. i'm not sure where you get reptiles w/wings, but i'll drop that.
That "growth overtime" as you put it could simply be various species of primate, or even evidence of microevolution (which I said I'm not refuting).
There have never been any fish found that had legs.
One of the basic premises of Macroevolution is that every form of life started from the same single cellular organism. Therefore, somewhere along the line, a fish had to grow legs (and go from having a respiratory system that is made for underwater breathing, to one made for open air breathing), eventually, this fish would turn into a dinosaur, and eventually these reptiles would have to slowly evolve with half formed wings (which by itself would be refuted by natural selection...undeveloped wings would only get in the way and eventually lead to the dieing out of that species), and eventually we would have lizards with wings.
darwin got his ideas when he vistied the galapagos. he noticed that the same species had traveled to different islands but had slowly started to evolve away from each other. its in action today. one good example is the vampire birds (i believe in the galapagos also). we have their relatives in other places, but they have adapted on the galapagos to suck the blood out of other birds (well, they bite them w/their beaks and eat up). after having them cataloged for some time now, scientists have noticed there beaks have actually gotten smaller and thinner, better to do their job.
That's microevolution, and again, I'm not refuting it. But when one of these bird turns into a mammal, I'll admit I'm wrong.
evolution is only a theory in the sense that we don't know everything about it. but look around you, its everywhere. i could explain myself more, but my mom taught me to not waste my energy, i will never get people to change their mind.
Evolution is a theory developed by a man who thought bugs were formed spontaneously from old food left lying around.
We have found numerous fossils of reptiles, fish, and birds from millions of years ago, but yet not a single fossilized remain of any transitional species that, according to the Theory of Evolution, should have abounded.
If we'd had evidence to prove the Theory of Evolution, then it wouldn't be called a theory anymore.
