poorcollegekid; I am afraid that link does not prove anything regarding evolution, it even states it does not. The closest it comes to proving anything is when it states that "The fossil record could show a chronological progression in which bird wings are gradually transformed into reptilian arms;"
I would like to apply emphasis on the word "could". The word "could" in that sentence provides a clear line of theory and conjecture, it does not provide proof.
Under the transitions from reptiles to mammals section of the article it even states "So far this series is known only as a series of genera or families; the transitions from species to species are not known."
Under the transitions from reptiles to birds it states "On the whole, though, this is still a gappy transition, consisting of a very large-scale series of "cousin" fossils."
I could go on, but I am sure you have read the article and can point on the many inconsistincies as well as I.

Second, we should not confuse adaptation with evolution, nor should we consider variation within a species evolution. For instance, there are hundreds of different types/breeds of dogs, but they are all dogs. We can cross breed to produce different traits within these dogs, but they are still dogs. The same can be done with all kinds of birds, fish, etc., but they all remain birds, fish, etc.

Third, there has not been one documented proof of a species in mid transformation, or of a species that has actually evolved ie. a bird became a reptile, a moth became a bird, a fish became a turtle, etc.

Fourth, in response to your mention of Galapagos finches. There are more color variations among pigeons than among any other animal or bird in the world. That is the result of only a couple centuries of intensive breeding by fanciers in Europe and America. In spite of the variations, they can all interbreed and are just pigeons.
The same can be said of the finches. There are currently 13 accepted species of Galapagos finches. A couple of centuries of breeding amongst themselves is the only thing that brought about these "changes". They are still all Galapagos finches. None of them have ever changed into pigeons, or anything else for that matter.


Lastly this from Darwin; "In fact the belief in Natural Selection must at present be grounded entirely on general considerations [faith and theorizing] . . When we descend to details, we can prove that no one species has changed . . nor can we prove that the supposed changes are beneficial, which is the groundwork for the theory. Nor can we explain why some species have changed and others have not."—*Charles Darwin, letter to Jeremy Bentham, in Francis Darwin (ed.), Charles Darwin, Life & Letters, Vol. 3, p. 25.
