What does Darwin's theory of evolution suggest?

• species change over time

• extinct species are not related to living species

• different species can interbreed

• animals that look alike are most closely related

Why were the beaks on Darwin's finches so Important?

• They showed the finches always existed as Darwin found them.

• They showed that the finches could mutate their beaks whenever they want.

• They showed variability in the finches species. All finches were equally adaptable to all islands.

• They show that the finches adapted to their environments. Their beak shape matched the food available on each island.

What most likely caused the finches on the Galapagos Islands to have beaks that were differnt from the finches living on the South American mainland?

• They were different types of food available on the island.

• The finches on the islands had to drink salt water.

• There were different types of predators living on the island.

• The finches on the mainland built different types of nests.

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 trait is an acquired phenotype.
