"then surely you ca n't explain away why enzyme a and co-enzyme b are separate compounds but work together to produce another by-product ."
"Well , in the case above , it was step-by-step . First , an existing enzyme was modified to a new use , and over time , became refined to work better and better . This is the way evolution works . Nothing is de novo ; it 's always a modfication of something else . Second , a mutation produced a regulator that only allowed the enzyme to be produced if the substrate was available . Again , this was refined by natural selection over time . In the end , the newly-evolved system was irreducibly complex , because all three parts have to be present for the system to work . And do show us your numbers proving that such processes ca n't produce new information . If you do n't know how , I 'd be pleased to show you how a mutation changes the information in a population ."
