Researchers at Cornell University measured the wing and leg bones of 111 bat species and 149 bird species from around the world.

They observed in both bats and birds that the shape of the bones within a species' wing (handwing, radius, humerus) are correlated.

This means that, contrary to birds, bats' forelimbs and hindlimbs did not evolve independently.
