    OK, maybe it's a bit extreme to say "from nothing". However, I don't
    think it's unreasonable to expect that something that is in principle
    capable of flying should evolve from something that does not have
    that capability. And alongside the evolution of the wing, must also
    evolve the ability to learn how to fly. (Note the this is more
    subtle and hard to define than the mere discovery of a correct
    sequence of motor actuation instructions - in one case there is a
    target sequence - or set of possible target sequences -, and in the
    other you have a self-tuning control system).
