Supposedly, even evolutionists recognize this, as they rush to alternative mechanisms like Gouldian punctuated equilibria.
They also reveal a previously unsuspected saturation behavior that may allow us to distinguish between gradualism and punctuated equilibria in the evolutionary history of real clades.
Quantum evolution and punctuated equilibria in continuous genetic characters.
This is consistent with the basic tenet of punctuated equilibria theory associating evolutionary change with speciation (Eldredge and Gould 1972; Stanley 1975; Gould and Eldredge 1977).
If the environment typically remains constant this could account for the pattern of punctuated equilibria, as observed in the fossil record.
