If a lion charges the line between two zebras, she catches grass and air. Yet with so many black and white lines all moving against each other, she has to define outlines and keep them crisp in her mind.
When it isn’t zebras, things get even more complicated, don’t they?
Herbivore prey tactics involve passive distraction/camouflage and simple flight. Predator tactics involve intelligence to defeat such subterfuge. Predators, usually carnivores or omnivores, thus form the basis for sentient species.
The lion should stop to refocus on every line to picture things more clearly
That lion would swiftly die of hunger. He’s only just barely faster then the zebras as it is. Stop to refocus, and lunch gets away.
Reality is never ideal.
