In Darwin’s Black Box, Behe takes evolutionary biology to task for failing to explain the evolution of biochemical pathways within the cell. From this he developed the idea of “irreducible complexity” - that there are systems that are too complex to have arisen by (known) evolutionary processes. From there, he makes the jump to an “intelligent designer“…in other words, failure to come up with an evolutionary explanation is proof of God. Of the the central “icons” of intelligent design is the bacterial flagellum. Despite the fact that far more is known about the evolution of the flagellum than was known a decade ago (when Behe wrote his book), ID proponents still cling to it as a pillar of their anti-evolutionary arguments. In his talk at OU on Monday, one of Dembski’s main criticisms of “Darwinian evolution” was the fact that it failed to provide a “complete, fully articulated path” of evolution for “molecular nano-machines”.
