“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 want to argue that the “sudden” appearance of species in the fossil record and our failure to note subsequent evolutionary change within them is the proper prediction of evolutionary theory as we understand it. […] Evolutionary “sequences” are not rungs on a ladder, but our retrospective reconstruction of a circuitous path running like a labyrinth, branch to branch, from the base of the bush to a lineage now surviving at its top.”

“Many people think there are no transitional species because the only fossil forms they’re aware of at all are a handful of plastic pieces in a prehistoric play set. They’ve no idea how rich the fossil record is! We know of several hundred species just within dinosaurs, to say nothing of the thousands of examples of each of hundreds more taxa apart from that. Experts estimate that all the collective genera still roaming around now only amount to about 1% of all the species that have ever lived. Practically everything there ever was ain’t no more. Every species living today has definite relatives both extant and extinct, and evident in the fossil record. And in one sense, all of them, even the things still alive, count as transitional species.”

“At the core of punctuated equilibria lies an empirical observation: once evolved, species tend to remain remarkably stable, recognizable entities for millions of years. The observation is by no means new, nearly every paleontologist who reviewed Darwin's Origin of Species pointed to his evasion of this salient feature of the fossil record. But stasis was conveniently dropped as a feature of life's history to he reckoned with in evolutionary biology. And stasis had continued to be ignored until Gould and I showed that such stability is a real aspect of life's history which must be confronted-and that, in fact, it posed no fundamental threat to the basic notion of evolution itself. For that was Darwin's problem: to establish the plausibility of the very idea of evolution, Darwin felt that he had to undermine the older (and ultimately biblically based) doctrine of species fixity. Stasis, to Darwin, was an ugly inconvenience.”

“The species with eyes appears suddenly, capriciously as it were, and it is this species which changes the environment by creating its visible aspect. The eye does not come into being because it is needed. Just the contrary; because the eye appears it can henceforth be applied as a serviceable instrument. Each species builds up its stock of useful habits by selecting among, and taking advantage of, the innumerable useless actions which a living being performs out of sheer exuberance.”

“Becoming vegan is the most important and direct change we can immediately make to save the planet and its species.”

“Hooke was aware that the fossil ammonites, nautili, and many other shells and fossil skeletons found in England, were of different species from any then known”

Charles Lyell book Principles of Geology

Chpt.3, p. 37
Principles of Geology (1832), Vol. 1
Context: Respecting the extinction of species, Hooke was aware that the fossil ammonites, nautili, and many other shells and fossil skeletons found in England, were of different species from any then known; but he doubted whether the species had become extinct, observing that the knowledge of naturalists of all the marine species, especially those inhabiting the deep sea, was very deficient. In some parts of his writings, however, he leans to the opinion that species had been lost; and in speculating on this subject, he even suggests that there might be some connection between the disappearance of certain kinds of animals and plants, and the changes wrought by earthquakes in former ages. Some species, he observes with great sagacity, are peculiar to certain places, and not to be found elsewhere. If, then, such a place had been swallowed up, it is not improbable but that those animate beings may have been destroyed with it; and this may be true both of aerial and aquatic animals: for those animated bodies, whether vegetables or animals, which were naturally nourished or refreshed by the air, would be destroyed by the water, &c.; Turtles, he adds, and such large ammonites as are found in Portland, seem to have been the productions of the seas of hotter countries, and it is necessary to suppose that England once lay under the sea within the torrid zone! To explain this and similar phenomena, he indulges in a variety of speculations concerning changes in the position of the axis of the earth's rotation, a shifting of the earth's center of gravity, 'analogous to the revolutions of the magnetic pole,' &c.; None of these conjectures, however, are proposed dogmatically, but rather in the hope of promoting fresh inquiries and experiments.

“When two sympatric, closely related species appear to have very similar needs, we may ask whether mechanisms exist that enable them to avoid direct competition. Implicit in this questions the presumption that two species with identical requirements cannot coexist”

“I've been looking into the issue for more than thirty years, and I have never seen a hint of genuine evidence of species-to-species transitional forms in the fossil record. The theory stands or falls on the supposed links between species. Even if you came up with what you believe is evidence, time would prove it to be another hoax, as it has so often in the past.”
