The human brain

dhw: As usual, you have ignored my question.

DAVID: Just because I didn't mention anticipation our 315,000 brain shows just that.

dhw: “As needed by the new changes” does not mean “as will be needed by changes that will not happen until two or three thousand years later”. You have agreed that your God does NOT guide complexification, and all past brains would have continued to complexify until new requirements exceeded their capacity for complexification. The enlarged brain in all cases, including our own, would have been a response to new requirements, as would subsequent complexifications. Once more: A response to new requirements does not entail anticipation.

Our 315,000-year-old brain seems to handle all new requirements from its appearance when little was required of it. Of course that is anticipation.
