Charles Darwin pointed out in The Descent of Man (1871) that natural selection would act to preserve those individuals which were least encumbered with a superfluous part. Rather than argue that neo-Darwinian processes are insufficient to account for the gradual evolution of irreducibly complex systems, couldn't the case be made that natural selection would actually prevent major evolutionary change from occurring on a gradual step-by-step basis and thus help account for the natural phenomenon of stasis?
