Re: Feduccia (was: polarity of bipedality in dinosaurs)

     It isn't a question of whether or not Archaeopteryx could fly.  The 
question is how it could get airbourne.  Taking off from the ground 
requires a lot more strenuous flapping than just the ususal flapping a 
birb uses when in the air.  During WWII, some Germans discovered that if 
you sever the pectoralis muscles in a pigion, it cannot take off from the 
ground, but if you toss it out a window its other arm and shoulder 
muscles are strong enough for it to flap and sat airbourne.
