OK, Yockey may be an overestimate but even by your admission, the standard
anti-evolutionist argument against evolution is wrong. The standard
argument says that one and only one permutation will function. In fact
Thaxton, Bradley and Olseon, Mystery of lifes Origin says that one and only
one permutation of the 4 million mer long DNA will produce an E. coli. (See
thaxton Bradley and Olson, p. 138) the "-kTln(1)" term means that only 1
permutation will work. This of course is quite wrong.

And when you apply selection as a search algorithm, it becomes quite
probable that one workable molecule will be found. Especially when you
realize the vast number of molecules that have some functionality.
