Islands are more prone to invasion by alien species because of the lack of natural competitors and predators that control populations in their native ecosystems. If marsupials were found all over the world, then that would mean they did not come into existence by means of natural selection and the evolutionary process. For example, islands situated in remote regions of the oceans are physically isolated from other landmasses. Fragmentation is the second most common threat to island species, as different islands are developed at different speeds and with different policies.
