Feduccia's objection is eliminated by simply realizing that dinosaurs, like
bird flight itself, developed from the trees down. I find it absolutely
astounding that the >possibility< (let alone the reality) of secondary
flightlessness in _Caudipteryx_ and _Protarchaeopteryx_ seems not to have
occurred to the describers.
