What evidence supports the theory that all 13 species of finches on the Galapagos Islands arose out of a single species from the mainland of South America?

• The finches all have specialized beaks

• The finches only mate with ones who look similar to them

• none

Which describes natural selection?

• Random assortment of genes results in better characteristics in the following generations.
