'Homologous structures' refers to:

• body parts of two different species that have similar structure and location in each species

• body parts that have the same function, but very different structures.

• structures that sound the same.

• two organisms that have about the same sized parts of their structure.

The evolutionary history of the Earth and its fossil record is incomplete because____________.

• all organisms leave a fossil imprint.

• Darwin didn't finish writing it.

• plants don't evolve and don't leave fossils

• many organisms don't leave behind fossils, making gaps/missing links.

How is natural selection in the evolution of long necks in giraffes best explained?

• Shorter-necked giraffes were killed by longer-necked giraffes.

• Giraffe necks grew longer because of the bone structure of the animal.

• Giraffes with longer necks survived because they were better suited to the environment.

• Long-necked giraffes mated only with other long-necked giraffes.

According to Darwin’s theory of natural selection, why do species evolve over time?

• Only the fittest organisms survive to reproduce.

• Members of a species work together to survive.

• Organisms cause changes to their environments.

• Organisms produce only organisms that can survive.

Why would the dark-colored mutation of the peppered moth be beneficial in a polluted area?

• They have a longer life span than light-colored moths.

• They cannot be seen as well by predators.

• They taste bad to most of their predators.

• They produce more young than do light-colored moths.
