Patterns of Evolution (Notes 2)

Which pattern of evolution results in one species splitting into many different species over time?

• Coevolution

• Sexual selection

• Speciation

• Convergent Evolution

This pattern of evolution describes slow changes that occur in a population over a long period of time

• Punctuated Equilibrium

• Gradualism

• Coevolution

• Extinction

The last Tasmanian tiger died in captivity in 1939. What pattern of evolution occurred in the Tasmanian tiger's population?

• Extinction

• Gradualism

• Divergent Evolution

• Coevolution

This pattern of evolution describes short bursts of evolutionary change in a population of organisms, followed by periods of stability (no change).

• Gradualism

• Coevolution

• Punctuated Equilibrium

• Speciation

Multiple groups of mammals descended from a common ancestor. What pattern does this describe?

• Convergent Evolution

• Divergent Evolution (Adaptive Raidation)

Dolphins and sharks are not related (no common ancestor), but they have similar body structures such as fins for swimming. Which pattern does this describe?

• Convergent Evolution

• Divergent Evolution (Adaptive Radiation)

When two organisms evolve in response to each other, such as with bees and flowers.

• Coevolution

• Gradualism

• Sexual selection

• Divergent Evolution
