    Seagulls have wings and can fly. Ostriches have wings and can’t fly. So it’s not the wings that make the seagulls fly, it’s something else entirely.

      This is in a way true. If ostriches weight less or had bigger wing area (like, absurdly large), they would be able to fly. So it isn’t the wings per se as you say. Interesting.
