Why? The same evolutionary advantage would be conferred through unconscious computation. Blindsight shows that perceptual function does not necessarily rely on conscious presentation. If we had no perception ourselves, we could never guess that such a phenomena could exist or that it could improve survival in any way, any more than it would improve a neuron's odds of successfully signalling to another if it played the theme song from Hawaii Five-0 to itself every time it depolarized. > Even bacteria > perceive chemical gradients.

Everything that they do to survive could be accomplished unconsciously and mechanically. From a functionalist perspective, perception can only be purely ornamental gravy. In reality, I think that it's the survival-and-existence part that is the gravy, perception is the essential meat and potatoes.
