The theory of evolution by natural selection means that what is changing over time?

• The inherited traits of a population.

• The acquired traits of a population.

• Hair color and eye color

• Attractive features.

Why are advantageous (helpful) traits more likely to be passed onto offspring?

• Because the parents with the trait are more likely to survive and reproduce.

• Because they come from dominant males

• Because the parents with the trait died before reproducing

• Because the trait is an acquired by the environment

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 

• No, they change because of natural selection

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Which best describes the role of mutations in natural selection?

• Mutations help an organism to better survive in their environment

• An organism may acquire a helpful mutation by interacting with the environment

• A mutation may result in an adaptive trait that makes an organism more likely to survive and reproduce

• Organisms with certain traits are more likely to win competitions for mutations
