Sentences with phrase «punctuated equilibrium»
"Punctuated equilibrium" is a phrase used in biology to describe how a species doesn't change much over a long time, but then suddenly undergoes a rapid change in a short amount of time. It's like a long period of stability interrupted by a sudden burst of significant change. Full definition
The evolutionary theory of Punctuated Equilibrium seems to apply to the human consciousness as well as biological adaptation.

While some scientists believe there was indeed an explosion of diversity (the so - called punctuated equilibrium theory elaborated by Nils Eldredge the late Stephen J. Gould - Models In Paleobiology, 1972), others believe that such rapid acceleration of evolution is not possible; they posit that there was an extended period of evolutionary progression of all the animal groups, the evidence for which is lost in the all but nonexistent precambrian fossil record.
In an often quoted remark, Gould stated, «Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists — whether through design or stupidity, I do not know — as admitting that the fossil record includes no transitional forms.
As for punctuated equilibrium, it certainly does not logically indicate preprogrammed adaptive ability.
One of the findings that stands out, he says, is that pop music shows a pattern from biological evolution known as punctuated equilibrium, in which periods of gradual change are separated by explosions of complexity.
I'm interested to know why, if we have a supposed plethora of transitional forms, did Punctuated Equilibrium get pushed forward.

Chad, not only have I watched the video, but I understand what punctuated equilibrium «is» and how it fits in perfectly with our current understanding of the evolutionary process.
It's off the mark at every step (which I guess is why allopatric speciation remains the ONLY theory on how punctuated equilibrium occurs): — it requires that a mutation be present in the population and not get weeded out, which is not what is seen at all (gene pools wobble about the genetic mean for long periods of time).
The acceptance of punctuated equilibrium put to death the then prevailing thought that gradual change was the evolutionary mechanism of speciation (Darwinian phyletic gradualism, which had held sway for > 100 years, was utterly debunked)

«This study supports the idea that punctuated equilibria exist but also suggests a limit to its overall effect on genetic change,» comments Don Waller, an evolutionary biologist at the University of Wisconsin, Madison.
But because it posits that evolution happens in bursts, punctuated equilibrium goes against the notion that evolution inches forward in tiny steps guided by natural selection.
