They aren't monkeys and they don't really fly, but the story of flying lemurs just got twice as interesting. Genetic material has revealed that one species of the acrobatic primate is really three.
Called colugos, flying lemurs aren't even really lemurs, but they are excellent gliders. A membrane of skin transforms its body into a flat parachute and allows colugos to soar over long distances of up to 450 feet from treetop to treetop. These mammals are the closest living relatives to primates (humans are primates too), having diverged from that group about 86 million years ago during the Late Cretaceous.
