Ch15: Darwin's Theory of Evolution

During Darwin's time on the Beagle he experienced an earthquake. How did this influence his ideas?

• It showed how organisms that lived in the ocean could live on land.

• It showed how features could be changed by gradual processes

• It showed how populations change over time to become better suited to their environment

• It showed that all living things are engaged in a constant struggle for survival

A characteristic that makes an organism well suited to its environment is called a(n)?

• natural selection

• trait

• adaptation

• variation
