I heard an interesting theory about intelligence while watching a documentary about jumping spiders. Good eyesight tends to evolve first. In the case of jumping spiders, it was vital for safe landing. As a consequence, jumping spiders have the best eyesight among spiders. Anyway, initially brain gets a lot of extra information but is unable to take advantage of all of it. It's just for safe landing. Then those animals that find way to exploit the extra data become more effective. Jumping spiders are devious, for example they can lure prey by mimicking gestures the insect uses.
