7B Fossils

The hypothesis that evolution of a species occurs gradually over time as a slow and constant process is known as

• speciation
• punctuated equilibrium
• gradualism
• microevolution

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 gradually and slowly over long periods of time

• Homeostasis

• Stasis

• Punctuated Equilibrium

• Gradualism

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.

How do fossils support evolution?

• Individual species disappear and reappear in the fossil record over time.

• Organisms in the fossil record are identical to living organisms.

• The fossil record provides evidence that all organisms developed at the same time.

• The fossil record provides evidence that organisms have changed over time.

Which of the following provide evidence for evolution? (Select all that apply)

• physical features

• molecular features, such as DNA

• geographical information

• fossils

According to the diagram, which organism is older?

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

• divergence

• punctuated equilibrium

• gradualism

• isolation

The hypothesis that evolution of a species occurs gradually over time as a slow and constant process is known as --

• speciation.

• punctuated equilibrium.

• microevolution.

The formation of a new species is a process known as ___________________, which is typically the result of divergence.
