That article is a truly great read, in particular this:
Consider the eye. Creationists have long maintained that it could not have resulted from natural selection, citing a sentence from On the Origin of Species: "To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest degree." But in the next passage, invariably omitted by creationists, Darwin ingeniously answers his own objection:
Reason tells me, that if numerous gradations from a simple and imperfect eye to one complex and perfect can be shown to exist, each grade being useful to its possessor, as is certainly the case; if further, the eye ever varies and the variations be inherited, as is likewise certainly the case and if such variations should be useful to any animal under changing conditions of life, then the difficulty of believing that a perfect and complex eye could be formed by natural selection, though insuperable by our imagination, should not be considered as subversive of the theory.
Thus our eyes did not suddenly appear as full-fledged camera eyes, but evolved from simpler eyes, having fewer components, in ancestral species. Darwin brilliantly addressed this argument by surveying existing species to see if one could find functional but less complex eyes that not only were useful, but also could be strung together into a hypothetical sequence showing how a camera eye might evolve. If this could be done - and it can - then the argument for irreducible complexity vanishes, for the eyes of existing species are obviously useful, and each step in the hypothetical sequence could thus evolve by natural selection.
A possible sequence of such changes begins with pigmented eye spots (as seen in flatworms), followed by an invagination of the skin to form a cup protecting the eyespot and allowing it to better localize the image (as in limpets), followed by a further narrowing of the cup's opening to produce an improved image (the nautilus), followed by the evolution of a protective transparent cover to protect the opening (ragworms), followed by coagulation of part of the fluid in the eyeball into a lens to help focus the light (abalones), followed by the co-opting of nearby muscles to move the lens and vary the focus (mammals). The evolution of a retina, an optic nerve, and so on would follow by natural selection. Each step of this transitional "series" confers increased adaptation on its possessor, because it enables the animal to gather more light or to form better images, both of which aid survival. And each step of this process is exemplified by the eye of a different living species. At the end of the sequence we have the camera eye, which seems irreducibly complex. But the complexity is reducible to a series of small, adaptive steps.
