>>This is one of *two* good models for the origin of insect flight.

The other involves derivation from semi-aquatic forms similar to dragonfly
nymphs.  It turns out that small extensions of the thorax have some useful
properties in a "nymph" trying to get to shore to lay eggs (I do not
remember the details, unfortunately).

This model has the advantage of starting with some of the least derived of
living insects - and one of the oldest living orders based on the fossil
record.

Really?  I'd never heard of that nymph theory.  Can anyone out there shed some
light on this?
