How it is possible...Squireel jump ...just owsome
Bats are the only mammals that truly fly, but they aren't the only ones you might see swooping overhead at dusk. For tens of millions of years, a variety of other furry vertebrates have also been soaring through forests, especially after dark.
Flying squirrels — which actually glide, not fly — date back to at least the Oligocene Epoch, and now come in 43 species across Asia, Europe and North America. They sail from tree to tree on a special membrane between each front and back limb, a trick that has evolved multiple times in history. (Aside from flying squirrels, it's also used by other aerial mammals such as anomalures, colugos and sugar gliders.)
just amazing
