48 The Origin of Birds and Flight

The logic on which such theories are based is so shallow that all the
conditions to be met for a living thing to fly are totally ignored. For arms
to gradually turn into perfect wings and achieve a structure that permits
total maneuverability would require a far more delicate adjustment
than random mutations could ever establish —99% of which are harm-
ful, in any case. Indeed, no scientific evidence supports such an idea.
In fact, according to natural selection—the alleged fundamental
mechanism that leads to evolution—any half-developed creature could
not survive while waiting for a random mutation, the work of pure
chance, to complete the process. Even if such an impossibility were in
some way overcome, many complementary features would have to be
acquired at the same time: Each bone in a dinosaur’s skeleton turning
hollow, the lung acquiring a wholly different structure, muscles suited
to tireless flight developing, the body assuming an aerodynamic shape,
