In the 16th century, a Spanish ship explored a Pacific Island that had a small mountain range separating it. Mice that were on the ship escaped onto the island on both sides of the mountain range. After decades of separation, the two populations developed different numbers of chromosomes, resulting in reproductive isolation that prevented any future interbreeding. This speciation event is an example of ____.
