Introducing the brain: general (Introduction)

DAVID: Same repeat: a logical God doesn't do secondhand design through others (your cells).

dhw: If your God wants to give autonomy to something, there is nothing illogical about his giving it autonomy! You agree that if he exists, he designed the complexification mechanism to work autonomously without his intervention. Why would it be illogical for him to do the same with expansion?

Expansion requires new design, especially our special five-tier frontal lobe cortex design. Complexification is simply a mechanism within a given design. Design works for the future.

DAVID: The five tier of frontal lobe neurons is extremely intricate and required very thoughtful design. I wish we knew what erectus had for comparison, but I'd guess it was less complex.

dhw: I don’t know which of my questions this is supposed to answer.

It answers your confusion about what design does.

Anticipation

dhw: You have completely ignored my question yesterday about WHAT was prepared/anticipated. If you mean that the mechanism for future complexifications was already there, then that would also be true of all the earlier homos. But do you mean that 315,000 years ago your God specially prepared certain cells to cope with the demands of language and of bilingualism, and so they just lay around for, say, 250,000 years doing nothing? I asked the same question about whales: did your God give them the mechanism to change legs to flippers, or did he look into his crystal ball and perform the operation to “prepare” them for a watery life at some time in the future?>

I've told you constantly design always considers the future. You constantly attack the point, which I get weary of answering. God speciates is my firm belief.

DAVID: As for language, our brain handled it well when language appeared. A brain arriving by a chance Darwin mechanism doing that is way beyond logical.

dhw: See above. How often do I have to repeat that I don’t accept chance either. As language developed, so the brain cells would have responded by making adjustments to accommodate the new usage of sounds.

DAVID: Exactly how God-provided complexification worked.

Thank you. Yet again you agree that complexification is a RESPONSE to new requirements, not an anticipation of them. So why do you go on telling me that I “approach complexification from a backwards viewpoint?”

Controlling spoken words

QUOTE: "New research has identified the part of the brain that makes sure our words are being properly articulated : the dorsal precentral gyrus. This knowledge could help treat speech problems and neural disorders in the future, the researchers say.

DAVID: our brain 315,000 years ago prepared to organize itself as part of its in initial design. Specific controls as described don't appear by chance.

dhw: I like the change from your God dabbling to the brain organizing itself, but I disagree profoundly with the idea that it prepared itself for requirements that would only arise 250,000 or so years later. Just like the whale’s anatomy “organizing itself” IN RESPONSE to different usages in the water, our brain would have “organized itself” IN RESPONSE to different usages, including the development of language.

DAVID: And did it by the God-provided complexification mechanism using the excess neurons in part of the process

dhw: Once again you agree with me that brains and bodies organize themselves, and that complexificaton results from the change and does not precede it. Our only point of disagreement is that your God gives organisms ”excess” neurons, whereas I believe that new neurons would not be created without an immediate purpose.

From above: "Expansion requires new design, especially our special five-tier frontal lobe cortex design. Complexification is simply a mechanism within a given design. Design works for the future." Complexification exists in the now, fully designed to work immediately.
