From the first realization that organic life on this planet has evolved over geologic time, scientists have speculated about the time interval required for these changes to occur. For many years Darwin's idea of slow incremental changes, gradualism, was the accepted model. In the 1970s Stephen Gould (1941-2002) and Niles Eldridge (b. 1943) provided an alternative model of very rapid evolutionary change, followed by long periods of stability, which they called punctuated equilibria. It now… Expand

Evolutionary mode routinely varies among morphological traits within fossil species lineages
Recent studies have revitalized interest in methods for detecting evolutionary modes in both fossil sequences and phylogenies. Most of these studies examine single size or shape traits, oftenExpand

Punctuated equilibria; the tempo and mode of evolution reconsidered
TLDR
It is argued that virtually none of the examples brought forward to refute the model of punctuated equilibria can stand as support for phyletic gradualism; many are so weak and ambiguous that they only reflect the persistent bias for gradualism still deeply embedded in paleontological thought.

Coordinated stasis: An overview
TLDR
An important goal for evolutionary paleoecology should be to document the patterns of stability and change in common and rare members of fossil assemblages in order to discern the relative frequency of coordinated stasis in the rock record, to evaluate the mechanisms by which such apparent evolutionary and ecological stability might be produced, and to seek clues of abrupt pulses of faunal change.

TLDR
Since paleontologists have been successful in recognizing true "biospecies" on criteria which are as valid and complete as those used to differentiate the majority of recent species, a reappraisal of paleontological models of speciation is called for. Expand
