Evolution requires inheritance, mutation, and selection.
Dr. Behe's process involves only inheritance and mutation. There are limited ways it can be modified and still function in the cell. That is true. The exact ways a particular protein can differ without destroying function have been investigated experimentally with exquisite technique. A protein is in essence a chain of discrete beads or elements of finite number and of describable relative availability for stringing.
