Although Darwin did not know about genes, he could see that animals of the same species who had slight variations that helped them to survive longer could produce more offspring than animals who were not as well equipped. Which of the following could be an example of a variation that would help a group of animals survive?

• B) Finding fossils of any kind in rocks from the Devonian period is unusual.

• C) Devonian rocks would not contain mammal fossils, because mammals appeared in later time periods.

• D) Mammal fossils and amphibian fossils will not be found in Devonian rocks, because the two types of animals live in different habitats.
