Re: vaulting pterosaur launch, questions
Apart from bringing one back to life somehow, exactly how do we
"properly" establish that Archie flew? The fossil evidence is entirely
consistent with an animal that was most likely at least a rudimentary
Actually, it's a bit mixed in this regard.
How did it fly? By flapping its wings.
Okay, very funny :) Seriously, though, there's a lot to this question of
importance: it includes launch, power output, flapping kinematic, and
Seriously though, these questions are equally as valid for all flapping
flyers, not just Archie.
Why did it fly? Who the heck knows! You might as well ask why do we walk?
Or why do fish swim?...
I think Scott meant "why" as in "under what stimulus" - as a mode of
travel between elevated points, or as a predator escape, or something else
The correct question isn't "why" Archie flew, but under what conditions did
flight became preferentially selected among pre-avian maniraptorans? Archie
flew because it inherited the apparatus for flight from its ancestors. Why
those ancestors developed that apparatus is an entirely different question.
