> Biology is destiny, no matter what your dreams are. Short people will never play in the NBA no matter how hard they practice. Dumb people will never get smarter by studying. Ugly ducklings grow up into freaky-looking ducks, not swans.

You'd have to make quite a stretch to say "never" for all of these. Short people do play in the NBA: Nate Robinson, Muggsy Bogues, and Ty Lawson come to mind. Try proving that "dumbness" is determined at birth by biology. And ugly ducklings growing up into freaky-looking ducks is a generalization, not a rule. Sure, there are some features people inherit that make them beautiful, but as one grows up there is a lot one can do to even the playing field (e.g., exercise, dress better, even plastic surgery)
