Re: *Archaeopteryx* Is Not A Penguin

  Do the feathers of the penguin differ aerodynamically from
that of the falcon to alter the ability of passivity? I
understand that penguins reduce their feathers and increase
their aspect ratio to compensate for their medium, and gain the
most thrust and "lift," and if the same features were applied in
the air but correspondingly to body size, the penguin would be
the most powerful flier.
