Please ignore yesterdays post on consciousness. It doesn’t really fly as a friend pointed out. Take away half of the brain, or cut the connection between the brain and consciousness pushes forward (probably, I’ve never researched).
Just to define what I mean by consciousness; meta cognition. The realization that we know we exist.
Better guess, is that meta cognition is just part of the evolutionary development of the brain. But I don’t know enough about the brain to figure out which parts are older and which parts are newer.
