Darwin on evolution of the eye (Talk.Origins)
Charles Darwin acknowledged the inadequacy of evolution when he wrote,
"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 possible degree." (Darwin 1872)
