Evidence of Evolution Review

When comparing different animal's bone structures and biological similarities, these similarities might suggest that?

• these animals have the same bone that is used to help them fly.

• these animals may have a common ancestor

• these animals were all born at the same time.

• these animals can only survive if they live together.

A remnant or trace of an organism from the past is called a _______.

• Skeleton

• Fossil

• Imprints

Why are vestigial structures evidence for evolution?

• They are useful in the organism and show natural selection at work.

• They are not useful in the organism but they were probably useful in some ancestor of that species.

• They show that these organs or behaviors help an organism adapt to new environments
