Not sure about the 10% point. You could imagine that we got “lucky” and a handful of simple proteins manage to produce the brain (or at least enough of the brain’s connections that the rest can be filled in during infancy via sensory input). Or put another way, maybe evolution optimized for brains that are incredibly adept while only taking a small number of codons (relative to the number of neurons) to describe. The fact that we've managed to l describe the universe through a small set of laws shows that the laws of the universe require much less space to encode than the universe itself, so it's theoretically possible.
