Llamas are dangerous, so if you see one where people are swimming, you shout: Look out, there are llamas!

They're sideways facing eyes, but a bit diagonal. Definitely not forward facing though. They're just a bit bulgy.

Or they need it that way to learn kung-fu

Idk if "descendants of omnivores" counts because then you could exclude a number of critters like pigs for being "descendants of herbivores" and then 'why do pigs have more stereoscopic vision than a t-rex '

The obvious caveat is that pandas at the minimum don't have selective pressure for side eyes or they have something pressuring stereoscopic vision even more similar to how aquatic animals have less selective pressure for forward facing eyes.

I would imagine the way pandas eat bamboo stalks is more visual than most herbivores and that alone could help them retain steroscopic vision.

They stopped eating meat 3 million years ago. That's longer ago than the appearance of the first animal of the genus Homo.

Pandas stopped eating meat about 3 million years ago. That's before the first being of the genus Homo appeared. Not Homo Sapiens (that was 300 000 years ago), but Homo Habilis (2.5mio years ago).

If evolution can take us from something that's barely an ape to humans in that time frame, you'd expect that it can fix an omnivour's digestive system to work with plants.

LOL no. Gatherers and trappers at most.

By far. We didn't get to be #1 by fucking around, and we didn't get to be #1 without all that dominating evolution lingering around. We're so good at it, we're predators to ourselves because there's no prey left to dominate. Every other species dies farmed or as a hobby.

But I can say, that if I were die be prey to something, I'd rather it be to a human. Everything else starts eating you before you're even dead lol.

LOL no.

You don't need a unified theory of why animals have binocular vision.

The biggest threat to a primate isn't always felines, it's often other primates. Judging distance to your target is a very beneficial trait for survival if you need to fight them. Which means if you need to survive other primates, it is beneficial to be able to judge distance to other primates. Even if you're not a predator.

Gorillas might be herbivores. But they are excellent at fighting eachother. And a dead gorilla can't reproduce.

Yeah, and you don't have to be a carnivore to be a predator.

Plus evolutionary history shows plenty of examples of animals switching from pure carnivore to pure herbivore to omnivores in between, and back the other direction. All birds are descended from a common carnivorous ancestor, but plenty of birds today subsist mostly on seeds or fruit.

If there is a lot of available biomass to be eaten, nature will find a way and some animal is going to fill that niche. Many of the folivores (herbivores specializing in digesting leaves) that descended from carnivores have to deal with the low nutrient/calorie density of their foods by just eating a lot of it, and have varying levels of microbial symbiosis for helping with that digestion.

Ah, I guess you are but you put it in a different place in your sentence compared to the comic, which confused me at first as it can be interpreted both ways with how you wrote it. Either way, the rest of my comment should still be relevant.

...too bad for the internet, eh?..

Well, better as front-faces, the capability to focus on a point in front, since a 3D vision is essential for a predator, to be able to accurately calculate distances. Insects and arthropods often combine side and frontal vision, if they are predators, obtaining a vision in practically 360º, for example dragonflies and also jumping spiders or hunters, these usually have two large eyes in front and 6 smaller side eyes. Chameleons solve this with eyes that can move independently, only focusing on the front before the attack. In small animals a wide field of vision is necessary, even if they are predators, since they themselves appear on the menu of others.
