A number of animals have evolved aerial locomotion, either by powered flight or by gliding. Flying and gliding 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 amphibious animals have also evolved to acquire this gliding flight ability, typically as a means of evading predators.

Famous quotes containing the words flying, gliding and/or animals:
“Y’know plenty of people, in their right mind, thought they saw things that didn’t exist, y’know, like flying saucers. The light was just right, and the angle and the imagination. Oh boy, if that’s what it is, then this is just an ordinary night. You and I are going to go home and go to sleep and tomorrow when we get up that sun’s gonna shine. Just like yesterday. Good ol’ yesterday.”
—Theodore Simonson. Irvin S. Yeaworth, Jr.. Steve Andrews (Steven McQueen)
“One might call habit a moral friction: something that prevents the mind from gliding over things but connects it with them and makes it hard for it to free itself from them.”
—G.C. (Georg Christoph)
“We know what the animals do, what are the needs of the beaver, the bear, the salmon, and other creatures, because long ago men married them and acquired this knowledge from their animal wives. Today the priests say we lie, but we know better.”
—native American belief, quoted by D. Jenness in “The Carrier Indians of the Bulkley River,” Bulletin no. 133, Bureau of American Ethnology (1943)
