Further, when you look at the type of insects and plants native to oceanic islands, they are from groups that are the best colonizers. Most of the insects are small, precisely those that would be easily picked up by wind. Compared to weedy plants, trees are relatively rare on oceanic islands, almost certainly because many trees have heavy seeds that neither float nor are eaten by birds. (The coconut palm, with its large buoyant seeds, is a notable exception, occurring on almost all Pacific and Indian Ocean islands). The relative rarity of trees, in fact, explains why
Notes:
The fact that the species that exist on islands could only have migrated there versus the ones that do not exist are evidence of evolution.
