Also see the rather stupid reply from the Discovery Institute. Really, how can ya pretend to be scientific when you write such replies: "
Yet notice that the only cases of systems where we observe optimization of signal to noise are (1) life and (2) human-engineered communication systems. Is lightning a communication channel from cloud to ground? No. Does it care about the carrying capacity of signal to noise? The idea is laughable. So is any other nonliving example of transfer of material: a star leaking its contents into a black hole, a river flowing from the mountains to the ocean, chunks of Mars arriving on Earth as meteorites. None of these are amenable to information theory. Environmental factors and laws of physics may act as constraints, but they do not optimize.
The uniqueness of optimization in signaling strengthens the argument for intelligent design in cellular communication as is self-evident in human-designed communication systems (e.g., software and computer networks). This is not to claim cells are intelligent, but rather to say they bear the stamp of purposeful design, just as a radio or smartphone does."
First of all it is incorrect, there are other systems where noise and signal are optimized (please define signal and noise...), second even IF that would be so does not logically result in an argument pro ID, and third, evolution has to result in optimization, that is logical and also in an increase of complexity (hence will often end up in life).
