Punctuated equilibrium is commonly contrasted against phyletic gradualism, the belief that evolution generally occurs uniformly and by the steady and gradual transformation of whole lineages (called anagenesis). In this view, evolution is seen as generally smooth and continuous.

∙ 10y agoThey both describe evolution as a gradual process. The difference is that in gradualism evolution is described as uniformly gradual, while in punctuated equilibria evolution can produce varying rates of change.

Does evidence support both punctuated equilibrium and gradualism?
Evidence supports a model in which periods of relative stability are punctuated by short periods of rapid (relatively speaking) change. It could, theoretically, be possible for evolution to proceed in a gradual manner. However, mathematical modelling and fossil evidence show that punctuated equilibrium is the norm.
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 models of evolution view change as occurring over a long time frame and at a relatively constant pace?
The view of evolution occurring relatively constantly over a long time frame is called gradualism. This stands in contrast to the view of long periods of stasis punctuated by relatively rapid change, usually caused by environmental change. This is called punctuated equilibrium.A modern view of evolution recognizes that both processes are at work.
Can you compare and contrast gradualism and punctuated equilibrium?
punctuated equilibria accounts for the gaps in the fossil record. Species evolve quickly during relatively short periods. Tiny changes in a species gradually add up to major changes over very long periods of time. Gradualism proposes that evolution occurs slowly but steadily. These periods of rapid change are separated by long periods of little or no change.
What is the model for the slow process of evolution?
Gradualism (as opposed to punctuated equilibrium).
How are the theories of gradualism and punctuated equilibrium different and similar?
Gradualism proposes that evolution occurs through a slow and continuous process, with small changes accumulating over time. Punctuated equilibrium, on the other hand, suggests that evolution happens in rapid bursts of change separated by long periods of little to no change. Both theories address the concept of how species evolve over time, but they differ in the pace and patterns of these changes.
The rapid development of bacteria resistant to penicillin is an example of gradualism?
Punctuated equilibrium
Is the rapid development of bacteria resistant to penicillin an example of gradualism?
Punctuated equilibrium
Compare gradualism to punctuated equilibrium?
Gradualism is when a change takes place over time. Punctuated equilibrium is when nothing changes for a very long time, then suddenly something new appears, after which another long period of no change occurs.
What is the model for the slow on going process of evolution?
Gradualism (as opposed to punctuated equilibrium).
How the gradualism model of evolution differs from the punctuated equilibrium model of evolution?
The gradualism model of evolution states that change occurs gradually over time. On the other hand, the punctuated equilibrium model states that change occurs suddenly or rapidly.
The theroy that evolution occurs slowly but steadily?
No, it happens in small leaps. This is called punctuated equilibrium. Gradualism is actually the answer to the question though punctuated equilibrium is also another tempo of evolutionary change.
What is meant by gradualism versus punctuated equilibrium?
When someone does not believe in intelligent creation, it can believe in anything. Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. Those terms were created when no missing link were never found. In the 1800's scientists were looking for missing links believing there were missing waiting to be dug up. Then came the punctuated equilibrium term when no missing was found.
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 must one accept that evolution follows either the pattern of punctuated equilibrium or the pattern of gradualism?
chicken pie
How does the fossil record differ for the gradualism model compared to the punctuated equilibria model?
Punctuated equilibrium is a model of a rapid mutation that happens rapidly or over a short period of time. On the other hand the gradualism model states that this change takes place slowly unlike the punctuated equilibrium.
