Yeah, I wondered about noctural animals. Also, they say: "This is a long-standing puzzle, even more so since the same structure, of neurons before light detectors, exists in all vertebrates, showing evolutionary stability." Which also strikes me as suspect since it could just be not worth correcting - evolution would have to get rid of the existing eyes and re-evolve them, just to fix a problem that isn't a *huge* handicap. (And it would have to do so because evolution "realised" that there was a better design available!) Still, it's interesting that there are (apparently) advantages to this setup, at least for some of us.
