It remains true, as every paleontologist knows, that most new species, genera, and families, and that nearly all categories above the level of families,…

Almost all paleontologists recognize that the discovery of a complete transition is in any case unlikely.

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…

Established species are evolving so slowly that major transitions between genera and higher taxa must be occurring within small rapidly evolving populations that leave…

Given the fact of evolution, one would expect the fossils to document a gradual steady change from ancestral forms to the descendants. But this…

Wherever we look at the living biota … discontinuities are overwhelmingly frequent…The discontinuities are even more striking in the fossil record. New species usually…

The extreme rarity of transitional forms in the fossil record persists as a trade secret of Paleontology. Evolutionary trees that adorn our textbooks have…

“The idea that one can go to the fossil record and expect to empirically recover an ancestor-descendant sequence, be it of species, genera, families,…

All geologic history is full of the beginning and the ends of species-of their first and last days; but it exhibits no genealogies of…

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…

If new species arise very rapidly in small, peripherally isolated local populations, then the great expectation of insensibly graded fossil sequences is a chimera.…
