Is there anything solid known about eye position (front vs. side of skull) and other aspects of an organism's life? It seems to me that front of the skull correlates with being a hunter, but (as is usual with biology) there may well be exceptions.
For example, lemurs aren't especially hunters, but they have eyes in front.
I was thinking that cats are both hunters and prey, and they have eyes in front.
Also, what about the evolution of eye position? How much of a lag is there if living conditions change?
Probably worth noting that fish, even predatory ones, don't necessarily have binocular vision, and vice versa for herbivores. Sperm whales are the largest living predators and lack it; fruit bats, who don't hunt, do have it.
There ARE incentives to develop it, or retain it, based on those lifestyle differences, but it makes for a somewhat fuzzy heuristic.
The other thing is this is pretty much restricted to fish and their mutant descendants, the tetrapods. Get outside the chordates and you find different solutions to these problems. Arthropods have several ...
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
