National Academy of Science account of evolution flawed?

Shouldn't teachers and the general public be able to depend on the National Academy of Science's "Science, Evolution, and Creationism" for an authoritative account of the mechanism of evolution? Could it contain a serious omission, even a logical flaw that invalidates the entire basis of the modern synthesis?

Of course it couldn't. I must be wrong.  But I can't see where. Can you point my error out to me?  Check out my argument here.
