Marsupials, such as kangaroos, koalas, and wombats, are mammals that care for their newborn young in a pouch. All
marsupials that are found in Australia are thought to have evolved from a single species that migrated to the island and the
adapted to the various niches. What does this example illustrate?
O behavioral adaptation
O adaptive radiation
O geographic isolation
O population explosion
