A theory of evolution advocating spurts of relatively rapid change followed by long periods of stasis.

A model of evolution in which change occurs in relatively rapid bursts, followed by longer periods of stasis.

In evolutionary theory, the periods of rapid change leading to development of new species are extended over a time line and separated by longer periods of no such change.

A theory devised by Eldredge and Gould (in 1972) based on the observation that in the fossil record species often show long periods of stasis, punctuated by rapid morphological change associated with [..]

theory that postulates that evolution is primarily cladogenetic, with new variation arising by speciation.

Punctuated equilibrium is the theory put forward by Eldredge and Gould to explain the fact that the fossil record does not show smooth evolutionary transitions. A common pattern is for a species to ap [..]
