Stephen Jay Gould, "Evolution as Fact and Theory" 1994 transitions are often found in the fossil record. Preserved transitions are not common—and should not be, according to our understanding of evolution (see next section) but they are not entirely wanting, as creationists http://www.stephenjaygould.org/library/gould_fact-and-theory.html - 25 kB - Dec 30, 2017 3. Stephen Jay Gould, "Opus 200," 1991 us each to apply a subject of evolutionary theory to the fossil record. He assigned me "speciation." I replied that I didn't know anything useful about speciation and would rather do "morphology" or "rates of change."

Eldredge, Gould, Coyne, and Charlesworth "On Punctuated Equilibria" 1997 the punctuated changes in the fossil record are said to occur via 'species selection,' in which descendant species rapidly supplant their ancestors"—a statement they attribute to Santiago F.

Carl Zimmer, "On the Trails of Macroevolution" 1998 In the fossil record, species often appear suddenly, hang on relatively unchanged for millions of years, and then vanish.

Ernst Mayr, "Speciational Evolution or Punctuated Equilibria," 1992 was a consequence of the notorious incompleteness of the fossil record.

The Growth of Biological Thought: Diversity, Evolution, and Inheritance either still living or in the fossil record, were very rare or absent. The gene-frequency approach of population genetics was quite unable to supply any solution to this problem of origination.

Stephen Jay Gould "Return of the Hopeful Monster" 1980 The fossil record suggests that macroevolution is indeed gradual, paced at a rate that leads to the conclusion that it is based upon hundreds or thousands of gene substitutions no different in kind from the ones examined http://www.stephenjaygould.org/library/gould_hopeful-monsters.html - 21 kB - Nov 24, 2017 17.
