Darwin studied which of these species on Galapagos?

• Pigeons and tortoises

• Finches and pigeons

• Finches and tortoises

• Zebras and mockingbirds

What might account for the fact that all of these limbs share similar structures?

• They came from a shared ancestor

• They are very similar organisms

• They are all from one animal

• Coincidence

Which of the following explains adaptation.

• An individual organism changes to meet its needs in the environment. These changes pass down to their offspring.

• The species as a whole changes their characteristics.

• Beneficial traits allow organism to survive and pass on those traits

• New characteristics arise in a species as needed.  If these traits are helpful, they are passed down.

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

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the organism knew it needed that trait, survives, and passes it on.

What is most likely to happen to moth populations in the picture shown?

• Light moths--hunted easily, dark moths--population increase

• Dark moths--hunted easily, dark moths--population increase

• Light moths--hunted easily, light moths--population increase

• Lights moths will change their color to match dark moths.

A population of rabbits grows rapidly from one year to the next. Then one year, a disease strikes approximately one fourth of the adult rabbits. The disease remains with the population in the years that follow.

As explained by Darwin’s theory, which of these conditions allows the rabbit population to evolve by natural selection?

• The disease affects adult and juvenile rabbits equally.

• The disease reduces the ability of the rabbits to reproduce.

• Some rabbits are resistant to the disease, and they pass the resistance to their offspring.

• No rabbits are resistant to the disease, and all die when the disease strikes them.
