"I just wonder: Which EYES are best - the ones that can FIND food; or the ones than can avoid BEING food??"

Heh-heh. Once again mixing up two different things that have to be independently evaluated, eh? Apples and oranges?

Kinds like evolution vs. ID?

'Best' is totally relative in your comparison.

Predators have eyes facing forward (TRex, birds of prey). The binocular aspect thus gained helps them identify movement and judge distances. Generally their vision is pretty good, for the same reasons.

Herbivores like Triceratops, for example, often have eyes on the sides. What they lose in depth perception they gain in having a much wider field of vision, reducing the chance that a predator can ambush them from behind (obviously identifying movement is also important for the same reason).

So, in terms of which vision is 'best', it all depends on what you are looking for - distance and depth, or breadth. both have their advantages, depending on whether you are the 'chomper' or the 'chompee'...

Indeed.

I wonder when the little chompee decided he/she/it wasn't gonna take it any more and started to be the chomper?
