Each plant and animal is exquisitely made; should not a supremely competent Designer have been able to make the intended variety from the start? The fossil record implies trial and error, an inability to anticipate the future, features inconsistent with an efficient Great Designer (although not with a Designer of a more remote and indirect temperament).

The history of most fossil species includes two features particularly inconsistent with gradualism: 1. Stasis. Most species exhibit no directional change during their tenure on earth. They appear in the fossil record looking much the same as when they disappear; morphological change is usually limited and directionless. 2. Sudden appearance. In any local area, a species does not arise gradually by the steady transformation of its ancestors; it appears all at once and “fully formed.”
I have attempted to show that the geological record is extremely imperfect; that only a small portion of the globe has been geologically explored with care; that only certain classes of organic beings have been largely preserved in a fossil state; that the number both of specimens and of species, preserved in our museums, is absolutely as nothing compared with the incalculable number of generations which must have passed away even during a single formation; that, owing to subsidence being necessary for the accumulation of fossiliferous deposits thick enough to resist future degradation, enormous intervals of time have elapsed between the successive formations; that there has probably been more extinction during the periods of subsidence, and more variation during the periods of elevation, and during the latter the record will have been least perfectly kept; that each single formation has not been continuously deposited; that the duration of each formation is, perhaps, short compared with the average duration of specific forms; that migration has played an important part in the first appearance of new forms in any one area and formation; that widely ranging species are those which have varied most, and have oftenest given rise to new species; and that varieties have at first often been local (emphasis not Darwin's). All these causes taken conjointly, must have tended to make the geological record extremely imperfect, and will to a large extent explain why we do not find interminable varieties, connecting together all the extinct and existing forms of life by the finest graduated steps. He who rejects these views on the nature of the geological record, will rightly reject my whole theory. For he may ask in vain where are the numberless transitional links which must formerly have connected the closely allied or representative species, found in the several stages of the same great formation. He may disbelieve in the enormous intervals of time which have elapsed between our consecutive formations; he may overlook how important a part migration must have played, when the formations of any one great region alone, as that of Europe, are considered; he may urge the apparent, but often falsely apparent, sudden coming in of whole groups of species. He may ask where are the remains of those infinitely numerous organisms which must have existed long before the first bed of the Silurian system was deposited: I can answer this latter question only hypothetically, by saying that as far as we can see, where our oceans now extend they have for an enormous period extended, and where our oscillating continents now stand they have stood ever since the Silurian epoch; but that long before that period, the world may have presented a wholly different aspect; and that the older continents, formed of formations older than any known to us, may now all be in a metamorphosed condition, or may lie buried under the ocean.
Ever since paleontology established the basic outlines of the fossil record more than a century ago, we have known how poorly the old chain of being matches the history of life. Its persistence as a metaphor and even, in Jastrow’s case, as an imposed “reality” merely reflects our unwillingness to abandon comfort in the face of evidence.
"The extreme rarity of transitional forms in the fossil record persists as the trade secret of paleontology. The evolutionary trees that adorn our text- books have data only at the tips and nodes of their branches; the rest is inference, however reasonable, not the evidence of fossils. Yet Darwin was so wedded to gradualism that he wagered his entire theory on a denial of this literal record:
"The geological record is extremely imperfect and this fact will to a large extent explain why we do not find interminable varieties, connecting together all the extinct and existing forms of life by the finest graduated steps, He who rejects these views on the nature of the geological record, will rightly reject my whole theory."
Darwin's argument still persists as the favored escape of most paleontologists from the embarrassment of a record that seems to show so little of evolution. In exposing its cultural and methodological roots, I wish in no way to impugn the potential validity of gradualism (for all general views have similar roots). I wish only to point out that it was never -seen- in the rocks.
Paleontologists have paid an exorbitant price for Darwin's argument. We fancy ourselves as the only true students of life's history, yet to preserve our favored account of evolution by natural selection we view our data as so bad that we never see the very process we profess to study.
[Evolution’s Erratic Pace - "Natural History," May, 1977]"
Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists—whether through design or stupidity, I do not know—as admitting that the fossil record includes no transitional forms. Transitional forms are generally lacking at the species level, but they are abundant between larger groups.
When something dies, it is usually disassembled, digested, and decomposed. Only rarely is anything ever fossilized, and even fewer things are very well-preserved. Because the conditions required for that process are so particular, the fossil record can only represent a tiny fraction of everything that has ever lived. Darwin provided many environmental dynamics explaining why no single quarry could ever provide a continuous record of biological events, and why it would be impossible to find all the fossilized ancestors of every lineage. But despite this, he predicted that future generations, -having the benefit of better understanding- would discover a substantial number of fossil species which he called “intermediate” or “transitional” between what we see alive today and their taxonomic ancestors at successive levels in paleontological history. In fact, in the century-and-a-half since then, we’ve found millions of evolutionary intermediaries in the fossil record, much more than Darwin said he could reasonably hope for. There are three different types of transitional forms and we have ample examples of each. But creationists still insist that we’ve never found a single one, because what they usually ask us to present are impossible parodies which evolution would neither produce nor permit.
Even before computers existed, we already knew that natural selection can, -and often will- produce results which look like trial-and-error experiments, including elements of seemingly-intentional fine tuning. But for all the implications of apparent design, there is never any indication of any intended goal or final product, nor any hint of infallibility on the part of the designer. In fact, so many errors of so many types are known that even if there was an unnatural architect using miraculous means instead of natural ones, then it seems that entity must either be blind and barely competent, or there are whole teams of designers working on separate lines competing against each other.
