@lothar @zeborah @Jdreben oh, I'm well aware of that one :-) But if UV vision was giving advantage, life would likely adopt that. I'm just trying to figure out why it doesn't (apparently) give any advantage.

P.S. As for X-Ray and generally higher-than-UV energy radiation, the answer, I think, is pretty simple: it didn't exist on Earth in appreciable quantities until humans started producing those.

@davidrevoy @lessanspages looks very much in your style! However, only the left face in the bottom row looks somewhat Asian to me :-)
