Quite often we see organisms that have similar characteristics, not because they have arisen from a common ancestor, but because they have adapted to similar environments. Which type of evolution is this?

• Divergent evolution

• Convergent evolution

• Punctuated equilibrium

• Coevolution

The flower developed a long flower to hold its nectar are the hummingbird in turn developed a long beak to get the nectar. This is an example of

• convergent evolution

• divergent evolution

• coevolution

SELECT ALL THAT APPLY: Which of the following must be true in order for organisms to be considered the same species?

• They must be able to mate

• They must be able to produce viable offspring

• They must have structural similaries

• They must have the same bone structure

Ostriches (birds) and giraffes (mammals) are both native to the savannahs of Africa.  They eat food that is high off the ground and share the same characteristic of an elongated neck.

• divergent evolution

• convergent evolution

• coevolution

The kit fox lives in the desert and has large ears with greater surface area that keep the fox from getting overheated.  The red fox lives in the forest and has a red coat that keeps it camouflaged.

Ants are the correct size and weight needed to open the flowers for the peony plant.  The peony plant provides food for the ant and the ant fertilizes the peony’s flowers

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

Some scientists suggest that the mass extinction of dinosaurs resulted from sudden global weather changes caused by the impact of an asteroid on Earth. This event most likely promoted the evolution of new species of animals. What concept is best supported by these ideas?

• Punctuated equilibrium

• Use and disuse

• Gradualism

• Convergent evolution
