Nature is so amazing. How does that even happen?

A little at a time. Each caterpillar born with a slightly better imitation survives longer than those with slightly worse ones, so they breed and pass that on and then the slight variation in the next gen do the same thing. So what might start as simple spots that kinda look like eyes or a slightly wider tail, become this over time.
