[Right Wing Professor]

(Quoting some idiotic bs): The problem is, wings would have no genuine survival value until they reached the point of flight. Birds' wings and feathers are perfectly designed instruments. Those with crippled or clipped wings cannot fly, and are bad candidates for survival. Likewise, the intermediate creature whose limb was half leg, half wing, would fare poorly -- it couldn't fly, nor walk well. Natural selection would eliminate it without a second thought.

That's why there are no flying squirrrels.

Lack of preditors: the reason there are so many nuts.
