Emus and other flightless birds are not proofs of evolution, as their change has gone into the wrong direction. They have lost a skill 8the ability to fly) that their ancestors once had.
Darwinian evolution would need diametrically different changes. A creature that was previously unable to fly should evolve the ability to fly. This has only happened in Darwinian storytelling but not in the real world.
