Punctuated equilibrium is the theory put forward by eldredge and gould to explain the fact that the fossil record does not show smooth evolutionary transitions. Hi, i agree that it is a bit difficult to draw out the point of this vignette and, like others who have responded here, i will try the title of the story is punctuated equilibrium.
Gradual change vs punctuated equilibrium charles darwin believed that evolution was a slow and gradual processhe did not believe this process to be perfectly smooth, but rather, stepwise, with a species evolving and accumulating small variations over long periods of time. The concept of punctuated equilibria (fig 1) was developed to explain a pervasive and intriguing evolutionary pattern: most species change little if at all after they first appear in the fossil record in many cases, individual species lineages persist for millions of years without showing any .

The evolution of innovation and the rule of punctuated equilibrium john nosta a long period of stasis is punctuated by more rapid and defining . Punctuated equilibrium is a hypothesis in evolutionary biology which proposes that speciation generally alternates between long periods of stability, and geologically rapid events of evolutionary change. Is there a problem with punctuated equilibrium summary of problems with claim: full discussion: explore evolution claims punctuated equilibrium is a more accurate description of the fossil record, but species selection doesn't work as a mechanism so punctuated equilibrium can't explain the origin of new body plans or new structures.
Arguments for and against the punctuated equilibrium theory of evolution as well as a description of what punctuated equilibrium is. Punctuated equilibrium model (pem) is an important model of organisational change in which change is relatively stable but experiences short bursts of fundamental change. Punctuated equilibrium (also called punctuated equilibria) is a theory in evolutionary biology which proposes that once species appear in the fossil record the .
It is the way that most natural systems evolve understanding punctuated equilibrium is essential to understanding how to change your life. Other articles where punctuated equilibrium model is discussed: stephen jay gould:in 1972 the theory of punctuated equilibrium, a revision of darwinian theory proposing that the creation of new species through evolutionary change occurs not at slow, constant rates over millions of years but rather in rapid bursts over periods as short as . Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists - by design or stupidity, i do not know - as admitting that the fossil record includes no transitional forms. Why does the punctuated equilibrium theory propose that once species appear in the fossil record they will become stable showing little evolutionary change.

Evidence for punctuated equilibrium lies in the genetic sequences of many organisms, according to a study in this week's science researchers report that about a third of reconstructed phylogenetic trees of animals, plants, and fungi reveal periods of rapid molecular evolution.
Supplement punctuated equilibrium is a theory describing an evolutionary change that occurs rapidly and in brief geological events in between the long periods of stasis (or equilibrium).
