<P> A number of animals have evolved aerial locomotion , either by powered flight or by gliding . Flying and gliding animals ( volant animals ) have evolved separately many times , without any single ancestor . Flight has evolved at least four times , in the insects , pterosaurs , birds , and bats . Gliding has evolved on many more occasions . Usually the development is to aid canopy animals in getting from tree to tree , although there are other possibilities . Gliding , in particular , has evolved among rainforest animals , especially in the rainforests in Asia ( most especially Borneo ) where the trees are tall and widely spaced . Several species of aquatic animals , and a few amphibians and reptiles have also evolved to acquire this gliding flight ability , typically as a means of evading predators . </P>
