What model of evolutions shows change over a relatively short period of time?
The theory of punctuated equilibrium. Developed by Niles Eldridge and Stephen Jay Gould.
What is the concept that evolution occurs over long period of stability that are interrupted by geologically brief periods of change known as?
This concept is known as Punctuated Equilibrium. A theory developed by Steven J Gould and Niles Eldridge.

How is gradualism evolution different from punctual evolution?
When Darwin first published his theories on evolution by natural selection, he envisaged evolution as a slow, steady process, with little variation in the rate of change. Later discoveries showed that this process was unlikely to be so slow and steady as was thought earlier; that in stead certain conditions enabled lifeforms to change rapidly, to develop significantly different morphologies in the course of less than 10.000 generations even. The first scientists to formulate such a model were S.J. Gould and N. Eldridge, and their model was called 'punctuated equilibrium'. To summarize: the significant difference between Darwin's gradualism and Gould's punctuated equilibrium is the variation in the rate of change.
What theory states that species stay the same and then change quickly because of environmental changes?
The term you're looking for is 'punctuated equilibrium', a model formulated in the 1970s by Stephen Gould and Niles Eldredge.This model describes how species can change very little over longer periods of time, followed by a shorter period of rapid change.To say that the only factors affecting those developments are environmental changes is oversimplifying the model a bit, I think. The period of rapid change could be triggered by anything from changes in the environment to population growth to changes in the structure of the population, and so on.
Rapid evolution with few intermediate forms?
This describes the theory of punctuated equilibriumdeveloped by Stephen Jay Gould and Niles Eldridge.
Why is Stephen Jay Gould a bane to Creationists?
Because he champions the validity of the scientific bases for the theory of evolution. He also effectively educates regarding the inadequacy of Creationism as a scientific theory.
What did Stephen gould do?
Stephen Gould is known for developing the theory of punctuated equilibrium. Stephen lived from 1941-2002 in the city of New York.
What did Stephen Gould invent?
Gould's greatest contribution to science was the theory of punctuated equilibrium which he developed with Niles Eldredge in 1972. The theory proposes that most evolution is marked by long periods of evolutionary stability, which is punctuated by rare instances ofbranching evolution. The theory was contrasted against phyletic gradualism, the popular idea that evolutionary change is marked by a pattern of smooth and continuous change in the fossil record.
What is Gould's theory of evolution?
Stephen Jay Gould did not propose a new theory of evolution per sé. He proposed a modification to the principle of uniform gradualism that had been the assumption until then. He proposed that the rate of divergence could vary greatly, depending on the circumstances. In his model, the morphology of species could remain superficially the same over long periods of time, followed by a rapid burst of divergence leading to new, distinct morphologies.

The theory that evolution occurs slowly but steadily is called?
Darwin's classic theory of evolution assumed that evolution is a slow, contunuous process, by which new species evolve and emerge. This is referred to at times as "organic evolution" and the "synthetic theory of evolution", or just the Darwinian theory of evolution. A newer theory, proposed originally by Niles Eldridge and Stephen Jay Gould is known as "punctuated equilibria", a model in which the evloution of new species occurs only periodically, in relatively rapid spurts. See "Time Frames the Rethinking of Darwinian Evolution and the Theory of Punctuated Equilibraia, Simon & Schuster, 1985"AnswerThe slow, constant process has also been called "gradualism."
How old is Stephen Jay Gould?
Stephen Jay Gould was born on September 10, 1941 and died on May 20, 2002. Stephen Jay Gould would have been 60 years old at the time of death or 73 years old today.
