Biodiversity on Oceanic islands is dependent on a number of factors. A. Unlike Oceanic islands that were once part of continental landmasses, islands formed by such geological processes as volcanism contain only plants and animals that could be transported there. B. An island's size is less important than its latitude in determining species diversity. C. Though biodiversity is low on many Oceanic islands, many native species have evolved that are uniquely adapted to their local environments. D. Species distribution in Oceania is determined by the location of islands, their size, and the direction of the wind. E. Most Oceanic islands are similar to one another in latitude and contain plants and animals typical of tropical islands. F. The absence of natural predators on the eastern Oceanic islands allowed many species of large mammals to evolve that were capable of inhabiting a wide range of territory
