Indeed. I'd have thought that the last thing you'd want to do if being
pursued by a predator would be to stick your arms out. Wouldn't this
actually slow you down? I've always thought that Archae's feet
carried recurved claws adapted for perching and grasping. Wouldn't
these also present a problem to a fast runner? Sort of like trying
to run in golf shoes...
