Evolution: more genomic evidence of pre-planning Part One (Evolution)

dhw: What do you disagree with?[/i]

DAVID: How we view the extra cells. I'll agree they might have been useful in the beginning, and I've given you a good reason why they gave us the ability to tailor our later use of our brains, and ended up as excess and jettisoned.

dhw: Over and over again you have argued that the new sapiens cells were excessive and brains overexpanded from the beginning. I’m delighted that you now agree that the cells were useful, which can only mean that the brain was NOT overexpanded. And over and over again I have explained that they only became “excessive” when enhanced complexification took over from expansion and proved so efficient that some cells were no longer needed. Welcome to my theory.

They were always excessive for final future use, no mater how you contort the descriptions

dhw: You are fixated on the idea that our brains were oversized, and all new cells were excessive....Once more, what logical flaw can you find in this theory?

DAVID: Your fixation is a total denial that extra cells removed means they were necessary. Irrational topsy-turvy reasoning. My version of your theory makes sense.

dhw: This is absurd. As I keep saying, the extra cells were necessary from the start.

It can also be said they were useful from the beginning for light use but not required for the heavier use later and dropped as excess. They were never meant to stay.

dhw: My point is that the autonomous ability to complexify and expand already existed prior to H. sapiens. There was no need for your God to perform operations to provide extra cells in anticipation of new requirements. The brain already worked autonomously as it does now, with cells RESPONDING to new requirements.

I agree past brains operated much like ours, but God gave us each step in bigger more complex brains. Brains did not grow themselves.

dhw: Again, I have no idea why you keep saying our brain was oversized, except that you are desperate to hold onto your idea that your God programmed or dabbled all changes IN ANTICIPATION of any requirements, whereas our brains show that the procedure is the opposite: our brains change IN RESPONSE to new requirements. Yes indeed, that limits our theories to the facts we have, despite your efforts to ignore those facts.

DAVID: Same irrational "Alice in Wonderland" nonsensical thought that extra cells that are removed are therefore useful and not excess.

dhw: Please stop pretending that I have proposed anything so silly. It is you who keep claiming that the brain was oversized (bolded above) because the cells were excessive (= not necessary)! The cells were useful from the beginning onwards and only became unnecessary when enhanced complexification took over.

DAVID: I've granted they once might have been useful, but when no longer necessary they become excessive and removed.

dhw: Correct. Once more, welcome to my theory.

I'm not following your theory. There can be no denying extra neurons were always present, and my interpretation grants they might have had some light use while they remained, but the excess neurons allowed us to remodel our brains to fit the heavy uses we learned to employ, language, abstract ideas, mathematics with invented number systems, etc. So heavily used brains are now 150 cc smaller. Making extras cells slightly useful in the beginning and then discarding them after complexification makes them an excess group of cells, used and then discarded
