This fossil snake and this living rat both have a structure in their skull called the quadrate bone. What best explains why both species have a quadrate bone?

• The snake and rat both share the same ancestor population that had a quadrate bone. They inherited this structure from the ancestor population.

• It is impossible to say. Fossils are very old; therefore, we cannot make observations of the snake’s ancestors, and we cannot explain its body structures.

• The snake and rat are different species, so they must not be related. They inherited the quadrate bone structure from separate ancestor populations.

• All species have their own specific body structures, so it is a coincidence that the snake and rat each happen to have the quadrate bone structure.

What does this diagram show?

• All three species share a common ancestor, but the bold jumping spider and Bombay locust are more closely related to each other than they are to the common octopus.

• All three species share a common ancestor, but the bold jumping spider and common octopus are more closely related to each other than they are to the Bombay locust.

• The three species are not related and come from separate lines of evolutionary history.

• All three species share a common ancestor and are equally related to one another.

The body structures for a population of chimpanzees were stable for a long time. Then, their body structures changed, making the chimpanzees stronger. Why did this happen?

• Their environment must have changed.

• Organisms naturally become stronger over time.

• It is impossible to say without more information

• The chimpanzee population wanted to be stronger.
