  2. Punctuated equilibrium - Wikipedia

    en.wikipedia.org/wiki/Punctuated_equilibrium

    However, the punctuational equilibrium model may still be inferred from both the observation of stasis and examples of rapid and episodic speciation events documented in the fossil record. [70] Dawkins also emphasizes that punctuated equilibrium has been "oversold by some journalists", [71] but partly due to Eldredge and Gould's "later writings ...

  4. Bak–Sneppen model - Wikipedia

    en.wikipedia.org/wiki/Bak–Sneppen_model

    The Bak–Sneppen model is a simple model of co-evolution between interacting species. It was developed to show how self-organized criticality may explain key features of the fossil record, such as the distribution of sizes of extinction events and the phenomenon of punctuated equilibrium. It is named after Per Bak and Kim Sneppen.

  5. Critical juncture theory - Wikipedia

    en.wikipedia.org/wiki/Critical_juncture_theory

    Gould's initial work on punctuated equilibrium was coauthored with Niles Eldredge. [20] Gould's model of punctuated equilibrium drew attention to episodic bursts of evolutionary change followed by periods of morphological stability. He challenged the conventional model of gradual, continuous change - called phyletic gradualism. [21]

  6. Extended evolutionary synthesis - Wikipedia

    en.wikipedia.org/wiki/Extended_evolutionary...

    The extended evolutionary synthesis was called for in the 1950s by C. H. Waddington, argued for on the basis of punctuated equilibrium by Stephen Jay Gould and Niles Eldredge in the 1980s, and was reconceptualized in 2007 by Massimo Pigliucci and Gerd B. Müller.

  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 ...

    The punctuated equilibrium model (above) consists of morphological stability followed by episodic bursts of evolutionary change via rapid cladogenesis. It is contrasted (below) to phyletic gradualism , a more gradual, continuous model of evolution.
