While I don't deny that any of this is true, I do question that any of
these are the reasons feathers developed in the first place. If you
weren't already flying you wouldn't need the added stability and
aerodynamics offered by body feathers. Then why would you have body
feathers? Don't they show up in early birds (like Archie) that are
probably not great flyers? Seems there must have been some other reason
that feathers first developed and later they adapted for use in flight.
