PNAS Authors Resort to Teleological Language in Failed Attempt to Explain Evolution of Irreducible Complexity


Summary: A recent article in Proceedings of the National Academy of Sciences (PNAS) purports to explain the evolution of a relatively small molecular machine in the mitochondria that transports proteins across a membrane, thereby allegedly refuting irreducible complexity. Phrases and assertions like “'pre-adaptation' to bacteria ahead of a need for protein import,” “parts accumulate until they’re ready to snap together,” “machines emerge before there’s a need for them,” or intelligently "engineered" macromutations are part and parcel of this latest failed attempt by critics of intelligent design (ID) to answer Michael Behe’s argument of irreducible complexity. As would be expected, when evolutionists are forced to resort to such goal-directed and teleological language and mechanisms, this shows that inherently, blind and unguided materialist explanations are not sufficient to produce irreducible complex systems. As discussed in more detail below, this latest attempt to answer irreducible complexity unwittingly shows the need for intelligent design. A summary of the problems includes:
