As stated, in a punctuated fashion. Organisms can be in stasis, adapted well to their environment for long periods of time, but can undergo rapid evolutionary change ( rapid in the geological sense ) with the proper environmental selection pressure.

∙ 13y agoWell, you have to be able to understand different aspects of evolution. In this case, there are 2 to consider:
1) Gradualism (Proposed by Darwin)
2) Punctuated Equilibrium (Gould and Eldredge)
In gradualism, the idea is pretty much that over time, we constantly and consistently came to be who we are. Butterflies today are who they are today because of constant changes over time. I guess you can think of it as one little thing happening at a time to make one whole new big picture (or in this case, organism).
In punctuated equilibrium, it's not constant over time. It proposes pretty much that we are who we are today because of set intervals of time where evolution occurred. For example, many years ago, we would have been apes. It followed for 2000 years then in a 10 year interval, we became another form, then 6000 years later, in a random 15 year interval, we became a closer form of human.
Hope that clears things up..

What is a model of evolution in which short periods of drastic changes in species are separated by long periods of little or no change?
Punctuated Equilibrium, I believe is the answer.
What is the name of the theory that states species evolve during short periods of rapid change?
It is called Punctuated Equilibrium. Some Evolutionary apologists, notably Richard Dawkins, have down played this aspect of Neo-Darwinistic theory.
What is evolution that occurs in short rapid bursts?
Punctuated equilibrium
The idea that new species occur suddenly in the fossil record followed by long periods of little change is called?
This is the idea called punctuated equilibria, by paleontologists Stephen Jay Gould and Niles Eldredge. It explains the patterns seen in the fossil record.
Is it possible for evolution to occur by both natural selection and punctuated equilibrium?
Yes. Evolution via punctuated equilibrium still depends on natural selection. In punctuated equilibrium there are long periods in which most species are well-suited to their environments, and so there is is little selective pressure to change. These periods are punctuated by times of more rapid environmental change and greater stress, which results in greater selective pressure for populations to change.

Punctuated Equilibrium, I believe is the answer.

What causes punctuated equilibrium?
zeological instrument of panther of indigeneous snake can do anything cause the punctuated equilibrium.
Pattern of evolution where a species is stable for a long time then rapidly changes?
punctuated equilibrium
A pattern of rapid evolutionary changes followed by long periods of no change is described as?
Punctuated Evolution or equilibrium
Over several thousand years the birds descendants evolve webbed feet and begin to feed on fish is this an example of gradualism or punctuated equilibrium?

What is fast and abrupt evolution?
Punctuated equilibrium.
What is the punctuated equilibrium hypothesis about?
The punctuated equilibrium hypothesis is a theory that most species have little evolutionary change throughout their geological history. They will remain in a state of stasis.
What is the relationship of speciation and the theory of punctuated equilibrium?
No difference.
