have to go with sierra on this one, its not the size its how it is used.
If it were a size thing, then whales and elephants would rule the world.
I am more inclined to think our brains are limitless and elastic enough continue expanding our boundaries.
Brains are certainly amazing things, and we do not understand how they work or their capacity. It is only by comparing it with things we do understand (like size) that we end up putting restraints on it.
A bit like the universe, sure there might be an end to its capacity, but is there?
