Sentences with phrase «punctuated equilibrium theory»

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.
The plenary address titled «Punctuated Equilibrium Meets Cancer: Big Promise Requires Big Change» will draw from evolutionary biology's punctuated equilibrium theory to set out why stable systems such as cancer research sometimes require swift and fundamental change to advance.

Not exact matches

If you'd like a real reference to understand PE, I'd suggest Gould's «The Structure of Evolutionary Theory,» particularly «Chapter 9: Punctuated Equilibrium and the Validation of Macroevolutionary Theory
The evolutionary theory of Punctuated Equilibrium seems to apply to the human consciousness as well as biological adaptation.
Punctuated equilibrium is commonly contrasted against the theory of phyletic gradualism, which states that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis).
In 1972, paleontologists Niles Eldredge and Stephen Jay Gould published a landmark paper developing this theory and called it punctuated equilibria.
3At present, for example, the well - entrenched neo-Darwinian hypothesis of «gradualism» (biological evolution occurs slowly, and more or less continuously as the constant interplay of random variations and natural selection over vast periods of time) is confronted with a somewhat more radical and neo-Lamarckian theory of «punctuated equilibrium» favored by Harvard biologists Stephen Jay Gould and Peter Williamson, collaborated by fossil discoveries of paleontologist and cultural anthropologist Richard Leakey in Africa.
Gradualism and punctuated equilibrium can co-exist — that some creatures have changed gradually and others have had long periods of stability doesn't invalidate evolutionary theory.
============ CONCLUSIONS A. # 1 is an accepted scientific fact, by theists and atheists, importantly: it does not in and of itself describe how we got from initial proto - cell to current complexity B. # 2 has a severe flaw, as phyletic gradualism is dead, and punctuated equilibrium (the fossil record being characterized by new species appearing fully formed) is an accepted fact C. # 3 is the ONLY theory that has support from the fossil record
They argue life could evolve in fits and starts — mirroring an evolutionary theory called punctuated equilibrium.
(The name comes from the theory of punctuated equilibrium, which Eldredge developed with Stephen J. Gould.)
They called the theory punctuated equilibrium.
Biden compared the current fight against cancer to the evolutionary theory of punctuated equilibrium, in which fires, floods, and other events that threaten the survival of species force them to either adapt or die, he said.
In 1972, paleontologists Niles Eldredge and Stephen Jay Gould published a landmark article presenting the theory Punctuated Equilibrium, thereby extending and combining Ernst Mayr's theory of geographic speciation and Michael Lerner's theories of developmental and genetic homeostasis.
Punctuated equilibrium is usually compared and contrasted with the theory of phyletic gradualism that holds that evolution occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis).
Those who subscribe to punctuated equilibrium say the fossil record is proof their theory concerning speciation is the correct one.
There's a theory in evolutionary biology called punctuated equilibrium.
Math is a tool, nothing more, it ties up loose ends or assists in making predictions or presenting probability or understanding how much how far, how fast, what angle, etc... When I read all of Gould's books, I realized how enormous evolution really is; punctuated equilibrium, endosymbiotic theory, etc... What I was referring to in regards to a quantity, is like looking at Henry's law, or Fick's law, Grahams law etc...
This did not prevent attacks from academics like committed Darwinist Richard Dawkins who said punctuated equilibrium was «an interesting but minor wrinkle on the surface of neo-Darwinian theory».
It's rather like the theory of «punctuated equilibria» in evolutionary biology.
