Undoubtedly, that could fly! But only if you fermented up a batch of wild berries and distilled them sufficiently before happy hour!
How do you ‘evolve’ feather that would EVENTUALLY allow you to fly?
Unless you sprout a set of full wings, anything less would be a detriment to your health and safety
I’ve heard the same argument for evolution of eyes - a bump turns into a ‘shadow sensor’ which evolves into a hole then closes up to form a pinhole camera and then grows a covering which grows an eye..
But at the intermediate steps you would have a hole that collects dirt and prone to infections which would probably hurt, no?
