Evolutionist Stephen J. Gould clearly stated that there are no transitional fossils. Still, he was not a creationist. He believed evolution happened only at certain moments, and so fast, that it left no traces in the fossil record (punctuated equilibrium).
Creationists have quote mined (ie taken quotes out of context) to falsely bear witness to what he said so many times that there is a whole project dedicated to correcting them:
quote:Claim CF002.1: Order does not spontaneously form from disorder. A tornado passing through a junkyard would never assemble a 747. Source: Hoyle, Fred, 1983. The Intelligent Universe. New York: Holt, Rinehart and Winston, pp. 18-19. Response:
1. This claim is irrelevant to the theory of evolution itself, since evolution does not occur via assembly from individual parts, but rather via selective gradual modifications to existing structures. Order can and does result from such evolutionary processes.
2. Hoyle applied his analogy to abiogenesis, where it is more applicable. However, the general principle behind it is wrong. Order arises spontaneously from disorder all the time. The tornado itself is an example of order arising spontaneously. Something as complicated as people would not arise spontaneously from raw chemicals, but there is no reason to believe that something as simple as a self-replicating molecule could not form thus. From there, evolution can produce more and more complexity.
So far you are not coming out with any good arguments for your position. Care to try again?
If you want to learn how evolution works, just ask.
The dashed lines show the overall trend. The species at the bottom is Pelycodus ralstoni, but at the top we find two species, Notharctus nunienus and Notharctus venticolus. The two species later became even more distinct, and the descendants of nunienus are now labeled as genus Smilodectes instead of genus Notharctus.
As you look from bottom to top, you will see that each group has some overlap with what came before. There are no major breaks or sudden jumps. And the form of the creatures was changing steadily.
Not 10 or 20 but hundreds. This also shows a speciation event where the breeding population divides into two daughter populations that no longer share genetic changes, and thus evolve separately, creating new diversity.
Now I expect you to find this doesn't show much change, and you would be correct. Evolution works that way.
If you want more, ask. It is not a problem being ignorant of the evidence and information ... if you are willing to learn.
A feathered dinosaur is any species of dinosaur possessing feathers. ...
Among extinct dinosaurs, feathers or feather-like integument have been discovered on dozens of genera via both direct and indirect fossil evidence. The vast majority of feather discoveries have been for coelurosaurian theropods. However, integument has also been discovered on at least three ornithischians, raising the likelihood that proto-feathers were also present in earlier dinosaurs, and perhaps even a more ancestral animal, in light of the pycnofibers of pterosaurs. Crocodilians also possess beta keratin very similar to those of birds, which suggests that they evolved from a common ancestral gene.
After a century of hypotheses without conclusive evidence, well-preserved fossils of feathered dinosaurs were discovered during the 1990s, and more continue to be found.
Sinosauropteryx fossil, the first fossil of a definitively non-avialan dinosaur with feathers
The most important discoveries at Liaoning have been a host of feathered dinosaur fossils, with a steady stream of new finds filling in the picture of the dinosaurbird connection and adding more to theories of the evolutionary development of feathers and flight. Turner et al. (2007) reported quill knobs from an ulna of Velociraptor mongoliensis, and these are strongly correlated with large and well-developed secondary feathers.

Behavioural evidence, in the form of an oviraptorosaur on its nest, showed another link with birds. Its forearms were folded, like those of a bird. Although no feathers were preserved, it is likely that these would have been present to insulate eggs and juveniles.
Do you agree that these fossils show intermediate development between reptiles and birds?
As mentioned earlier, Archaeopteryx is probably the most well-known transitional or intermediate fossil. According to Wikipedia 11 specimens have been found, plus a single feather that may be from Archaeopteryx lithographica. Specimens of Archaeopteryx has a very good discussion and some good photos.
I got to see one of the specimens last June at the Wyoming Dinosaur Center in Thermopolis.
The specimen is inside a glass pyramid and there is a holographic video the appears above it that slowly spins around as it changes from a skeleton into a fleshed out and feathered dinosaur that has front legs that are also wings. It was quite a thrill for me to see this fossil, something I never thought would happen. My wife walked up to me as I stood there and asked why I was crying......
These photos were taken with my phone so the quality is not great, plus the glass pyramid was quite scratched up. I wonder if they ever replace it?
The answer to the question, "where are all the transitional fossils?" is quite obviously, "In museum collections, by the tens of thousands."

One important characteristic of a theory is that is has survived repeated attempts to falsify it. Contrary to your understanding, all available evidence confirms it. --Subbie
If evolution is shown to be false, it will be at the hands of things that are true, not made up. --percy
Two decades ago, the first imprints of dinosaur feathers created great excitement. However, with the feathers themselves long gone, these impressions couldn't tell us much. More recently, feathers have been found in amber, preserving the original structure in a way rocks do not. However, a discarded feather with no indication of which dinosaur it belonged to is of only limited use to paleontologists.
So the discovery of eight vertebrae from the tail of a 99-million-year-old dinosaur, with feathers attached, is a game changer. The discovery has been announced in Current Biology, and the authors say it directly informs the evolutionary developmental pathway of feathers.
The feathers are brown on top with a pale underside. They more closely resemble ornamental plumage in modern birds than flight feathers and lack a well-developed central shaft (rachis), suggesting this was a feature that appeared later in feather evolution. The specimen is so well preserved, we can see that there were two rows of feathers evenly spaced along the tail. Given the age of the dinosaur when it died, the authors are unsure if these are adult feathers or would subsequently be replaced.
The discovery comes with further scientific potential, as scraps of surviving soft tissue can be seen and the high content of ferrous (Fe2+) iron suggests hemoglobin from actual dinosaur blood awaits analysis.
