Re: Campbell's even crazier than a MANIAC? (archeopteryx climbing)
Also worth noting is anything capable of powered flight, is capable of
Even rotorcraft like helicopters can glide (and indeed there are foot
launched autogyro gliders - i can supply video)
So I find the concept of a powered flight ability before a gliding ability
as some proposed completely false (although some of their examples of
gliding were albatross and vultures - such specialized gliding forms
aren't needed to glide, and soaring should be differentiated from
Its either powered flight in tandem with gliding, or gliding, then powered
I don't see how this follows.
I think its highly likely powered flight did not come before soaring.
The fossil record points in the opposite direction: the bats still haven't
got the idea of soaring, and the birds seem to only have evolved it after
the Mesozoic was over. Even the pterosaurs started with small forms that
didn't have particularly long wings.
