<< 3) Physics and functional anatomy have yet to disprove a gravity-opposing
("ground-up") origin of flight. Sure, it's more challenging that a
gravity-assisted origin of flight; but as long as its physically feasible,
it's on the table. Evolution does not have to take the "easiest" course; it
can only act on the raw material available. >>
I would say that evolution >always< takes the easiest course, which is
determined by the raw material available. This is because the chance of
finding the easiest course is much greater than that of finding a harder
course. That, indeed, is the definition of "easiest course."
In flight origins, gravitational energy is there for the taking.
