Bats are the only mammals that fly. Bats' ancestors lived in trees and ate insects and fruits. Somewhere along the line, a bat was born with a flap of skin that stretched across the finger bones.

After generations of bats, the fingers became very long and the thin membrane joined the fingers together to become wings.
