Evolution Quote by Evan Parker

History employs evolution to structure biological events in time.

— Stephen Jay Gould

At a minimum, in explaining evolutionary pathways through time, the constraints imposed by history rise to equal prominence with the immediate advantages of adaptation.

— Stephen Jay Gould

The primitive history of the species is all the more fully retained in its germ-history in proportion as the series of embryonic forms traversed…

— Fritz Muller

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

— Steven M. Stanley

In the last century, as we learned more about genes, we were able to devise ways of accelerating evolution.

— Nina Fedoroff

If we turn to palaeontology to tell us about our biological evolution it is to prehistory that we look for evidence of the evolution…

— John G. D. Clark

If evolution almost always occurs by rapid speciation in small, peripheral isolates, then what should the fossil record look like? We are not likely…

— Stephen Jay Gould

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

— Ernst Mayr

“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,…

— Gareth J. Nelson

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

— Stephen Jay Gould

I established the opposite view, that this history of the embryo (ontogeny) must be completed by a second, equally valuable, and closely connected branch…

— Ernst Haeckel

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…
