Interesting post on protein folding and evolution

A few months back, John Farrell, a Catholic writer and producer working in Boston, approached me, concerned over a creationist argument about the evolution of protein folding. I answered him best I could, but also put him touch with several people far more expert in this field than I am. It is pleasing to see the fruits of his enquiries laid on his own blog here:

The Evolution of Protein Folding: Is a Crisis Brewing for Darwin?
