If ID manages to demonstrate that certain biological tissues, organs, systems, or organisms are irreducibly complex...

How do you go about proving a negative? How many centuries, for example do you give science to plug the holes in Newton's equations before it becomes impossible? By what standard or logic or human experience do you declare something impossible?

You should be aware that every example of irreducible complexity from Behe's original formulation has become reducible with research.

Ask Darwin. "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down..."

As I said before, that's EXACTLY as it should work.

Well, at what point do you decide that it's effectively impossible for Mount Rushmore to have been sculpted by unintelligent forces alone?
