One of the more idiotic and demonstrably false claims by intelligent [sic] design creationists is that the human eye is so perfectly designed that it must have been intelligently designed by magic. This claim is even hilariously repeated by spectacle-wearing Ken Ham of the disinformation site, Answers in Genesis, blissfully oblivious of the contradiction his vision-correcting spectacles betray.
However, a few minutes studying vision in other vertebrates will show that the human eye is actually fairly ordinary and unremarkable as vertebrate eyes go. It lacks the visual acuity of an eagle's eye for example, and now, as this study shows, we can see (sorry!) our eyes lack the colour vision of birds; in this case a broad-tailed hummingbirds, Selasphorus platycercus.
