The arms of a human and the wing of a bat are structures, composed of the same bones that have been modified for different functions. The wings of insects differ from the wings of bird because the wings of birds contain many different feathers while insect Wings contain only some feathers only 2 or 4 not more than this . Why the wings of a bat and butterfly are considered analogous? For example, the wings of an insect, bird, and bat would all be analogous structures: they all evolved to allow flight, but they did not evolve at the same time, since insects, birds, and mammals all evolved the ability to fly at different times.
