  2. Punctuated equilibrium - Wikipedia

    en.wikipedia.org/wiki/Punctuated_equilibrium

    In evolutionary biology, punctuated equilibrium (also called punctuated equilibria) is a theory that proposes that once a species appears in the fossil record, the population will become stable, showing little evolutionary change for most of its geological history. [1] This state of little or no morphological change is called stasis.

  3. Stephen Jay Gould - Wikipedia

    en.wikipedia.org/wiki/Stephen_Jay_Gould

    According to Gould, punctuated equilibrium revised a key pillar "in the central logic of Darwinian theory." [17] Some evolutionary biologists have argued that while punctuated equilibrium was "of great interest to biology generally," [42] it merely modified neo-Darwinism in a manner that was fully compatible with what had been known before. [43]

  4. Punctuated equilibrium in social theory - Wikipedia

    en.wikipedia.org/wiki/Punctuated_equilibrium_in...

    The theory posits that most social systems exist in an extended period of stasis, which may be punctuated by sudden shifts leading to radical change. The theory was largely inspired by the evolutionary biology theory of punctuated equilibrium developed by paleontologists Niles Eldredge and Stephen Jay Gould .

  5. Court jester hypothesis - Wikipedia

    en.wikipedia.org/wiki/Court_Jester_Hypothesis

    The court jester hypothesis builds upon the punctuated equilibrium theory of Stephen Gould (1972) [8] by providing a primary mechanism for it. [2] The 2001 paper by Barnosky that is one of the first to use the term appropriate for the Court Jester side of the debate: the Stability hypothesis of Stenseth and Maynard Smith (1984), Vrba's Habitat Theory (1992), Vrba's Turn-over pulse hypothesis ...

  6. Group development - Wikipedia

    en.wikipedia.org/wiki/Group_development

    Chaos Theory is a concept taken from the physical sciences. It challenges models that postulate linear and sequential processes, and instead suggests that development is inherently unpredictable. Chaos theory argues that it's unrealistic for a system to go through deterministic, predictable, and repeated stages.

  7. Niles Eldredge - Wikipedia

    en.wikipedia.org/wiki/Niles_Eldredge

    Eldredge and Stephen Jay Gould proposed punctuated equilibria in 1972. Punctuated equilibrium is a refinement to evolutionary theory. It describes patterns of descent taking place in "fits and starts" separated by long periods of stability. Eldredge went on to develop a hierarchical vision of evolutionary and ecological systems. Around this ...

    Lovtrup also rejected the punctuated equilibria of Stephen Gould and Niles Eldredge, claiming it was a form of gradualism and not a macromutation theory. Lovtrup defended many of Darwin's critics including Schindewolf, Mivart, Goldschmidt, and Himmelfarb. [26]
