- falsedan 10y ago> searchlights or even lasers Think about the return on investment on these: how much energy to grow and power vs. the improved food gathering. Also: would this make the creatures easier to find by predators? Galagos developed large eyes rather than sonar, true. I refer you to my other comment: > Perhaps eyes convey a general advantage, regardless of how you find food?
- logicallee 10y agoI think we can all agree that my point is made, and it's easy to imagine sentient extraterrestrials without photoreceptors.
- Someone 10y agoIf you are a predator and carry a search light, chances are your prey will learn what your search light means. If you are prey, would you think it is a good idea to advertise "there's something to eat over here"?
