Question

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 then adapted to the various niches. what does this example illustrate?
o behavioral adaptation
o adaptive radiation
o geographic isolation
o population explosion

Explanation:

Adaptive radiation is when a single ancestral species evolves into many different species to fill various ecological niches. Marsupials in Australia evolving from a single - migrated species to different forms for different niches is an example of this. Behavioral adaptation refers to changes in behavior, geographic isolation is about being separated by geography, and population explosion is about rapid population growth.

Answer:

adaptive radiation
