I’ve engaged in some discussions about IC on this blog before and I found this link to be another good discussion on IC.
There’s a particularly good point in there:
The flagellum is a self-assembling, irreducibly complex microscopic rotary engine that contains parts known from human technology—such as a rotor, a stator, a propeller, a u-joint, and an engine—yet it functions at a level of efficiency that dwarfs any motor produced by humans. In any other context we would immediately recognize such an information-rich, integrated system as the product of intelligence.
This struck me as I read it, for we often hear things like, “Evolution is smarter than we are,” or that evolutionary algorithms produce results that we could not hope to attain. Yet, when we learn about non-optimized systems, like photosynthesis, Darwinists make comments about how it’s not surprising that evolution does not produce highly efficient products. Another example would be our appendix or junk DNA to a Darwinist. Those things are along for the ride and therefore very inefficient. It seems that this is another case of the Darwinist wanting to have her cake and eat it too. When we find something that is inefficient, it’s because evolution doesn’t work that way. When we find something highly efficient, like the bacterial flagellum, then it’s because evolution works that way. A hypothesis that can be used to explain everything really explains nothing.
