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

• coevolution

• punctuated equilibrium

• gradualism

• microevolution

Punctuated Equilibrium implies catastrophic events caused natural selection to speed up due to great environmental changes.

• True

• False

Slow changes over a long period of time.

• Gradualism

• Extinction

• Coevolution

• Convergent evolution

Bursts of change followed by periods of stability.

• Punctuated equilibrium

• Gradualism

• Extinction

• Speciation

A number of different species arise from one common ancestor.

• Adaptive Radiation (aka, Divergent Evolution)

• Gradualism

• Coevolution

• Speciation
