Punctuated Equilibrium

The idea that evolution seems to occur in spurts of time.

• stabilizing selection

• gradualism

• disruptive selection

• puntuated equilibrium

The hypothesis that the evolution of a species occurs in periods of rapid change separated by periods of little or no change is called:

​ (a)  

• Divergence

• Gradualism

• Isolation

• Punctuated Equilibrium

112.34.c.7.B

Proposes that species are stable most of the time, but every now and then there is a disruptive event that prompt rapid change. (a)  

• Transformational theory

• Theory of natural selection

• Punctuated equilibrium

• Gradualism

Answer explanation

SHORT burst of SPEED like a rabbit.

This theory say that evolution, or change, happens VERY FAST in between LONG PERIODS of NO CHANGE.

Usually forced by major change in the environment.

What is the difference between gradualism and punctuated equilibria?

• Gradualism is slowly but surely and P.E. are rapid changes preceeded followed by long periods of little or no change

• P.E. is slowly but surely and Gradualism are rapid changes preceeded followed by long periods of little or no change

• Gradualism had no intermediate forms of species

• punctuated equilibria has intermediate forms of species

What is a key characteristic of punctuated equilibrium?

• Evolution occurs at a constant, slow pace

• Evolution occurs in short, rapid bursts followed by long periods of stability

• Evolution is driven solely by natural selection

• Evolution is a result of genetic drift

Which best describes punctuated equilibrium?

• Speciation occurs due to natural selection

• Speciation occurs due to isolation

• Speciation occurs slowly in geologic time, followed by long periods with very fast evolutionary change.

• Speciation occurs suddenly and rapidly in geologic time, followed by long periods with little evolutionary change.

What type of evolution where there is a sudden, rapid change then no change for a long time?

• Co-Evolution

• Punctuated Equilibrium

• Divergent Evolution

• Convergent Evolution

Evolution occurring quickly due to catastrophic events

• Homeostasis

• Gradualism

• Statsis

• Punctuated Equilibrim

Which form of evolution can occur quickly?

• gradualism

• punctuated equilibrium

• allopatric speciation

• sympatric speciation

This model of evolution shows change over a relatively short period of time?

• gradualism

• skip-step evolution

• punctuated equilibrium

• evolution doesn't happen this way
