Imagine two small, isolated tropical islands located far from the mainland that are similar in size and physical characteristics. Although the islands have been habitable for millions of years, a small population of frogs occupies only one of the islands, having appeared there 30 years previously. What are two possible reasons why the frogs colonized the one island, and only relatively recently? What factor does not appear to have prevented them from colonizing the other island?
