On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection. It is believed that all of these species had one common ancestor and, over time, evolved into different species. After the burst of speciation in the Galapagos, a total of 14 species would exist: three species of ground-dwelling seed-eaters; three others living on cactuses and eating seeds; one living in trees and eating seeds; and 7 species of tree-dwelling insect-eaters. The finches varied mainly in the size and shape of their beaks. What statement BEST describes the speciation of the different finch species?
A) The species eat different foods.
B) The species all live on different islands.
C) The different species no longer interbreed.
D) The species no longer share any similar traits.
