Doesn irreducible complexity (as described in Behes Darwins Black Box) shown that some biomechanical systems could not evolve gradually, but must have all their parts created at once?
Behe’s “irreducible complexity” considers only an unrealistically simplistic model of evolution. Evolutionary mechanisms that Behe doesn’t consider, such as functional change and coevolution, make irreducible complexity not only possible, but expected. See Irreducible Complexity and Michael Behe FAQs and Irreducible Complexity Demystified [off site].
