Since I can tell this topic is interesting to you, if you haven't read it, I highly recommend "Brain Rules" by John Medina: http://www.amazon.com/dp/0979777747/

It's a fantastic read that I think would do a much better job of discussing this topic, especially in the realm of human cognition than I can.
