    It's easy to imagine flight evolving from
pouncing/parachuting behavior. Obviously some of these
keen lil mammals would see the predator coming and
make a run for it. Evolution would favor those animals
capable of controlling their descent with more
accuracy and prolonging "air time". That might explain
the increased EQ in some very bird-like maniraptors as
well as a more sophisticated auditory apparatus (e.g.
Troodontids). Anyway, I'm getting off topic here.....
