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?

• Organisms naturally become stronger over time.

• It is impossible to say without more information.

• The chimpanzee population wanted to be stronger.

• Their environment must have changed.

This fossil turtle and this living hawk both have a structure in their neck called the atlas bone. What best explains why both species have an atlas bone?

• The turtle and hawk are different species, so they must not share an ancestor population. They inherited their atlas bone structure from separate ancestor populations

• The turtle and hawk both share the same ancestor population that had an atlas 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 turtle’s ancestors, and we cannot explain its body structures.

• All species have their own specific body structures, so it is a coincidence that this turtle and hawk each happen to have the atlas bone structure.

What best describes the hind leg bones seen in the whale?

• The bones are analogous structures to the fins of living fish.

• The bones are vestigial structures that had a function in an ancestor.

• The bones are homologous structures to the wings of butterflies.

• The bones are fossil structures from an extinct ancestor.
