"Night vision" is not a special binary adaptation. It's not as if humans have exemplary might vision either, and we see LOTS of stars in a dark sky. Plus there are lots of diurnal reasons to not be helpless in low light, like tree cover and caves.
- XorNot 3y agoProbably more importantly, an obvious adaptation in such an environment for prey animals would be to hide in dark places like caves where predators can't see you...so predators would develop with low-light vision for hunting where other predators couldn't and in turn.... Basically evolution tends to do every weird thing it can - and we can't know which would be likely to end up as traits on the dominant intelligent species.
- rini17 3y agoWell, hiding under water is another obvious adaptation...but it does not automatically mean sea mammals evolved gills. They did evolve but in other ways. Some weird things just don't happen.
