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 animals, flying and/or gliding:
“If everything is perfect, language is useless. This is true for animals. If animals dont speak, its because everythings perfect for them. If one day they start to speak, it will be because the world has lost a certain sort of perfection.”
—Jean Baudrillard (b. 1929)
“No April can revive thy withered flowers,
Whose blooming grace adorns thy glory now;
Swift speeding Time, feathered with flying hours,
Dissolves the beauty of the fairest brow.
Oh let not then such riches waste in vain,
But love whilst that thou mayst be loved again.”
—Samuel Daniel (15621619)
“How soon unaccountable I became tired and sick,
Till rising and gliding out, I wanderd off by myself,
In the mystical moist night-air, and from time to time,
Lookd up in perfect silence at the stars.”
—Walt Whitman (18191892)
