A Quote by Stephen Jay Gould
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.

Transitional forms are generally lacking at the species level, but they are abundant between larger groups.
The extreme rarity of transitional forms in the fossil record persists as the trade secret of paleontology.
Why, if species have descended from other species by insensibly fine gradations, do we not everywhere see innumerable transitional forms.
The extreme rarity of transitional forms in the fossil record persists as a trade secret of Paleontology. Evolutionary trees that adorn our textbooks have data only at the tips and nodes of their branches; the rest is inference, however reasonable, not the evidence of fossils.
The fundamental problem in the origin of species is not the origin of differences in appearance, since these arise at the level of the geographical race, but the origin of genetic segregation. The test of species-formation is whether, when two forms meet, they interbreed and merge, or whether they keep distinct.
Every paleontologist knows that most new species, genera, and families, and that nearly all categories above the level of family appear in the record suddenly and are not led up to by known, gradual, completely continuous transitional sequences.
It remains true, as every paleontologist knows, that most new species, genera, and families, and that nearly all categories above the level of families, appear in the record suddenly and are not led up to by known, gradual completely continuous transitional sequences.
There are transitional forms between the metals and non-metals; between chemical combinations and simple mixtures, between animals and plants, between phanerogams and cryptogams, and between mammals and birds [...]. The improbability may henceforth be taken for granted of finding in Nature a sharp cleavage between all that is masculine on the one side and all that is feminine on the other; or that any living being is so simple in this respect that it can be put wholly on one side, or wholly on the other, of the line.
The several difficulties here discussed, namely our not finding in the successive formations infinitely numerous transitional links between the many species which now exist or have existed; the sudden manner in which whole groups of species appear in our European formations; the almost entire absence, as at present known, of fossiliferous formations beneath the Silurian strata, are all undoubtedly of the gravest nature.
When it was first proposed, I was willing to support it as a 'transitional fuel' because it had some clear advantages for Hawaii. Much has changed since then. LNG will no longer save us any money.
Anytime that is ‘betwixt and between’ or transitional is the faeries’ favorite time. They inhabit transitional spaces: the bottom of the garden, existing in a space between manmade cultivation and wilderness. Look for them in the space between nurture and nature, they are to be found at all boarders and boundaries, or on the edges of water where it is neither land nor lake, neither path nor pond. They come when we are half-asleep. They come at moments when we least expect them; when our rational mind balances with the fluid irrational.
There are gaps in the fossil graveyard, places where there should be intermediate forms, but where there is nothing whatsoever instead. No paleontologist..denies that this is so. It is simply a fact, Darwin's theory and the fossil record are in conflict.
Since Mia, my eldest, was born, we've been through the gamut of shelters, transitional housing and even living in a camper in a driveway.
Still, our creationist incubi, who would never let facts spoil a favorite argument, refuse to yield, and continue to assert the absence of all transitional forms by ignoring those that have been found, and continuing to taunt us with admittedly frequent examples of absence.
...the argument from absence of transitional types boils down to the striking fact that such types are always lacking unless they have been found.
The history of life is more adequately represented by a picture of 'punctuated equilibria' than by the notion of phyletic gradualism. The history of evolution is not one of stately unfolding, but a story of homeostatic equilibria, disturbed only 'rarely' (i.e. rather often in the fullness of time) by rapid and episodic events of speciation.
