A Quote by George Gaylord Simpson
Darwin recognized the fact that paleontology then seemed to provide evidence against rather for evolution in general or the gradual origin of taxonomic categories in particular.

Paleontologists had long been aware of a seeming contradiction between Darwin's postulate of gradualism, confirmed by the work of population genetics, and the actual findings of paleontology. Following phyletic lines through time seemed to reveal only minimal gradual changes but no clear evidence for any change of a species into a different genus or for the gradual origin of an evolutionary novelty. Anything truly novel always seemed to appear quite abruptly in the fossil record.
This general tendency to eliminate, by means of unverifiable speculations, the limits of the categories nature presents to us is the inheritance of biology from The Origin of Species. To establish the continuity required by theory, historical arguments are invoked, even though historical evidence is lacking. Thus are engendered those fragile towers of hypothesis based on hypothesis, where fact and fiction intermingle in an inextricable confusion.
There is not enough evidence, consistent evidence to make it as fact, and I say that because for theory to become a fact, it needs to consistently have the same results after it goes through a series of tests. The tests that they put- that they use to support evolution do not have consistent results. Now too many people are blindly accepting evolution as fact. But when you get down to the hard evidence, it's merely a theory.
Society in general maintains such a vested interested in its cozy habits and solidified belief systems that it had rather die - or kill - than entertain change. Consider how threatened religious fundamentalists of all faiths remain to this day by science in general and Darwin in particular.
Darwin's theory of evolution is a framework by which we understand the diversity of life on Earth. But there is no equation sitting there in Darwin's 'Origin of Species' that you apply and say, 'What is this species going to look like in 100 years or 1,000 years?' Biology isn't there yet with that kind of predictive precision.
The evidence for evolution pours in, not only from geology, paleontology, biogeography, and anatomy, but of course from molecular biology and every other branch of the life sciences.
The final and conclusive evidence against evolution is the fact that the Bible denies it.
The significance of a fact is relative to [the general body of scientific] knowledge. To say that a fact is significant in science, is to say that it helps to establish or refute some general law; for science, though it starts from observation of the particular, is not concerned essentially with the particular, but with the general. A fact, in science, is not a mere fact, but an instance. In this the scientist differs from the artist, who, if he deigns to notice facts at all, is likely to notice them in all their particularity.
You know, Darwin said through natural selection things go gradually, and he was talking about pigeon's evolution or horses evolving, getting faster. But in fact if you look at evolution on a bigger scale, cosmic evolution and you look at culture evolution you see it jumps, it goes through phase changes, and that's very exciting.
Darwin's book, On the Origin of Species, was published in 1859. It is perhaps the most influential book that has ever been published, because it was read by scientist and non- scientist alike, and it aroused violent controversy. Religious people disliked it because it appeared to dispense with God; scientists liked it because it seemed to solve the most important problem in the universe-the existence of living matter. In fact, evolution became in a sense a scientific religion; almost all scientists have accepted it and many are prepared to 'bend' their observations to fit in with it.
From the almost total absence of fossil evidence relative to the origin of the phyla, it follows that any explanation of the mechanism in the creative evolution of the fundamental structural plans is heavily burdened with hypothesis. This should appear as an epigraph to every book on evolution. The lack of direct evidence leads to the formulation of pure conjecture as to the genesis of the phyla; we do not even have a basis to determine the extent to which these opinions are correct.
We still do not know the mechanics of evolution in spite of the over-confident claims in some quarters, nor are we likely to make further progress in this by the classical methods of paleontology or biology; and we shall certainly not advance matters by jumping up and down shrilling, `Darwin is god and I, So-and-so, am his prophet'
Darwin repeatedly used the hypothesis of common ancestry as a platform on which to build his various ideas about testing hypotheses concerning natural selection. He also argued that adaptive similarities provide little or no evidence for common ancestry. Although this second claim needs to be fine-tuned, Darwin was right that ample evidence for common ancestry can exist even if none of the characteristics we observe were caused to evolve by natural selection.
Evolution is a theory, and it's a theory that you can test. We've tested evolution in many ways. You can't present good evidence that says evolution is not a fact.
anyone who writes about "Darwin's theory of evolutionin the singular, without segregating the theories of gradual evolution, common descent, speciation, and the mechanism of natural selection, will be quite unable to discuss the subject competently.
We know evolution happened not because of transitional fossils such as A. natans but because of the convergence of evidence from such diverse fields as geology, paleontology, biogeography, comparative anatomy and physiology, molecular biology, genetics, and many more.
