“So the mousetrap does a good job of illustrating how irreducibly complex biological systems defy a Darwinian explanation,” he continued. “Evolution can’t produce an irreducibly complex biological machine suddenly, all at once, because it’s much too complicated. The odds against that would be prohibitive. And you can’t produce it directly by numerous, successive, slight modifications of a precursor system, because any precursor system would be missing a part and consequently couldn’t function. There would be no reason for it to exist.”
