. Imagine that part of a population of South American finches is blown by a storm onto an island far offshore and manages to survive and reproduce there, establishing a new population. After 10,000 years, climate change results in lower sea levels and the reconnection of the island with the mainland. Members of the formerly isolated island finch population can now interact freely with members of the original mainland population. Which of the following observations would lead you to conclude that the island finch population had evolved into a distinct species, according to the biological species concept?
