Humming birds the masters of flight

Darwin Said in" the Origin Of the species" in chapter 6

"If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find out no such case"

Nature is full of just such examples in fact with few exception nothing can be shown to be able to come about in the way evolution insists upon. It is only by turning the question upside down Darwin side steps the issue. But lets consider one example the humming birds. Humming birds are a divers group with the amazing ability to fly, hover and fly backwards their wing structure is drastically different from other birds with the bones which in other birds would constitute the ends of the wings instead forming the whole wing. The mode of flight requires totally different controls and neurological programming as different as flying a helicopter is from a plane. By no steeple's modification could "the hand" bones with the altered muscle attachments replace the the arm and hand bone structure and remain functional at all steps and there are no transitions between utterly different flight modes. the interdependence of every part the of the system demands the whole be formed at the same time or flight would be impossible. Imagine the first mother bird hatching a offspring so deformed that its wings are mere flapping Hands as yet incapable of flight because the genetic programming of it brain is still not formed and the wing muscle are still to weak to flap are the needed speed? What would happen Natural selection would eliminate the creature as a matter of course long before the various coordinated changes could ever get started.
