Macroevolution Microevolution

Finches on the Galapagos Islands share similar characteristics because they share a common ancestor but have evolved into many different types of species to eat different foods in order to survive. What type of macroevolution is being described?

• adaptive radiation

• microevolution

• coevolution

• convergent evolution

• divergent evolution

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.

Two unrelated species evolve in a way that makes them more similar.

Evolution is

• A theory that life comes from non-living objects

• a change in a species over time; process by which modern organisms have descended from ancient organisms

• A theory that life come from life

• The species from whom a current one has descended
