What is the proof for Darwin's theory of undirected mutation and incremental change over other theories of evolution - punctuated equilibrium?

Punctuated equilibrium is not ' a theory of evolution ' but well ensconced within modern evolutionary theory. Scientists look for evidence, not proof. The evidence suggests that punctuated equilibrium and incremental change are not mutually exclusive and both can occur in nature.

Pattern of evolution where a species is stable for a long time then rapidly changes?
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 theory that evolution occurs during short periods of rapid change is puntuated?
Punctuated equilibrium.
Pattern of evolution where a spicies is stable for a long time then rapidly changes?
Punctuated equilibrium is the name of that pattern.
The concept that evolution occurs over long periods of stability that are interrupted by geologically brief periods of change is known as?
punctuated equilibrium
Pattern of evolution where a species is stable for a long time then rapidly changes?
punctuated equilibrium
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 fast and abrupt evolution?
Punctuated equilibrium.
What is evolution that occurs in short rapid bursts?
Punctuated equilibrium
A pattern of rapid evolutionary changes followed by long periods of no change is described as?
Punctuated Evolution or equilibrium
What is the model for the slow process of evolution?
Gradualism (as opposed to punctuated equilibrium).

What is the rapid evolution that can come about by the mutation of just a few genes'?
Punctuated equilibrium
What is the model for the slow on going process of evolution?
Gradualism (as opposed to punctuated equilibrium).
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.
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.
What is the Pattern of evolution where a species is stable for a long time than rapidly changes?
Punctuated equilibrium.
