Clotting system with reduced components were found. Molecular motors with reduced components were found. All Behe had to do was look to nature and he would not have been stuck in a court case having to admit that he cannot test for IR.No supposedly. It was an epic failure. They used to claim certain traits showed "irrefutable complexity". Every example was show to not be that complex.
The fact that it would be impossible to test every possible iteration of these so called 'irreducible' structures and systems means that IR cannot be demonstrated.
