Biology for AP Courses 2022-06-09T00:00:00Z There is a geological term, punctuated equilibrium, that proposes the Earth evolves, not steadily, but with long uneventful intervals ruptured by epochal change.

From James Taylor to Taylor Swift: Music evolves like biological organisms 2015-05-05T04:00:00Z For the case of punctuated equilibrium, the fossil record would show a geographic divide within the parent species that caused it to diverge into multiple new species. Biology for AP Courses 2022-06-09T00:00:00Z Schumpeter's ideas are a kind of economists' version of the biologist Stephen Jay Gould's take on evolution as happening mostly in transformational leaps, which he called punctuated equilibrium, rather than through gradual, incremental change. Technology as our planet's last best hope 2013-07-15T14:38:16Z Stephen Jay Gould called those big events a “punctuated equilibrium.” The One-Man Space Program 2012-09-19T15:30:22Z Years from now, when historians look back at the fossil record for the digital age, they will be puzzled by what appears to be a punctuated equilibrium — a Punk Eek of ideas. TED, meme-laundering and the ‘Punk Eek’ of ideas 2012-08-13T15:43:40Z This is sort of a political version of punctuated equilibrium. Kropotkin saw that there was an episodic nature to major political change that maps nicely onto the punctuated equilibrium view of biological change. The Prince of Evolution: Lee Alan Dugatkin on Peter Kropotkin, Anarchism, and Cooperation in Nature 2011-09-13T18:15:00.207Z With punctuated equilibrium, a species may remain unchanged for long periods of time. Biology for AP Courses 2022-06-09T00:00:00Z But so much on our present planet suggests that we're not in a world of steady, evolutionary development but of "punctuated equilibrium" of sudden leaps and discontinuous change. Why China may not be No. 1 2011-05-02T20:30:00Z While punctuated equilibrium suggests a faster tempo, it does not necessarily exclude gradualism. Biology for AP Courses 2022-06-09T00:00:00Z Graudal speciation and punctuated equilibrium both result in the divergence of species. Biology for AP Courses 2022-06-09T00:00:00Z Johnson: This sounds a lot like the theory of punctuated equilibrium that would later be proposed by Stephen Jay Gould and Niles Eldredge. The Prince of Evolution: Lee Alan Dugatkin on Peter Kropotkin, Anarchism, and Cooperation in Nature 2011-09-13T18:15:00.207Z This early change model is called punctuated equilibrium, because it begins with a punctuated or periodic change and then remains in balance afterward. Biology for AP Courses 2022-06-09T00:00:00Z How would you expect this pattern to differ from a pattern in the fossil record that supports the model of punctuated equilibrium? Biology for AP Courses 2022-06-09T00:00:00Z For the case of punctuated equilibrium, the fossil record would show new forms that persist essentially unchanged through several geological layers, then disappear just as a new form appears. Biology for AP Courses 2022-06-09T00:00:00Z For the case of punctuated equilibrium, the fossil record would show a steady progression of distinct forms. Biology for AP Courses 2022-06-09T00:00:00Z |
