Whatever today's level of knowledge about it, the brain does what the brain does inside the skull, no? If you remove the brain, then you remove the consciousness. Also, Roger Penrose has not received a Nobel prize; neither has Stephen Hawking. What I really wanted to stress is your expression "purpose" in evolution.

I agree in general, we have to be careful when using words such as "purpose" when discussing evolution. We can talk about evolution "choosing" animals with heavier coats when the climate gets colder, because the heavier coats serve a "purpose" in increasing the animal's survival advantage. Of course, this is just convenient talk: evolution is blind and stupid.
