PART ONE

The human brain

DAVID: Your view cannot explain how our brain could complexify so beautifully over 315,000 years unless enough neurons were present for all new necessary circuits required for complexification.

dhw: Why do you keep repeating what I keep telling you, and omitting the mistakes you kept making? YES, when our brains expanded to their present size, they contained enough neurons to meet all future requirements through complexification. They were never “excessive”, and the brain was never “oversized” because at the time of expansion – as you have now agreed – the neurons were used! You have now agreed that they did not lie around for thousands of years doing nothing! They could only have been used to meet a new requirement at the time.

I never assumed the extra neurons were dormant! But the new ones were available for complexification into the future until the brain reached a point where a new complex brain was needed. We agree in a way, but we don't have the same viewpoint. Each new brain had more neurons which implies they were provided for future use as well as immediate use. God speciating explains why the more complex brain appeared with the ability to handle the future. From a natural viewpoint, an existing primitive brain would not be concerned about the future requirements.


Cellular intelligence: the cancer problem

DAVID: The point is cancer cells are rogue living cells not like normal cells and are beyond God's control.

dhw: Yes, that is also my point. According to you, they have used their intelligence for destructive purposes, and your all-powerful, all-knowing God – who must have given them their intelligence – can’t control them.

God did not give cancer cells their abilities. The cancer cells usurped God's mechanisms and twisted them for their own purposes.


DAVID: I do not think the cancer cells are intelligent enough to invent the mutations that make them so independent and act with such seemingly intelligence.

dhw: So despite your “obvious evidence of cellular intelligence”, they are not intelligent enough to invent the mutations which led them to work out their nasty methods of survival. Then who did? Obviously only your God could have done it! He must have provided them with instructions for the nasty deeds they are not intelligent enough to perform! Curiouser and curiouser.

Mistakes in DNA reproduction from constant natural cell divisions produce the rogue DNA. God did not do it since they are chance mistakes.


Role of the centromere

dhw: Buehler’s book explains why he believes in cellular intelligence, and you have dismissed it because you think that new instruments have shown things he couldn’t see. And so I’m asking if the new instruments have disproved his theory?

DAVID: The centromere has disappeared as the cells were studied by newer methods.

dhw: The article you quoted was on the role of the centromere. I’m surprised to hear that it’s disappeared. My reference to Buehler was made because of my faulty memory. It was the centrosphere that he suggested was the seat of cellular intelligence.

DAVID: The point I am making is the centromere seems of no significance in current articles describing the workings of the cell. Your memory is correct, Buehler had a theory that the centromere ran the cell.

dhw: There’s a big difference between disappearing and being of no significance, but Buehler thought it was the centrosphere that ran the cell. Have modern instruments disproved his theory?

A centromere is never mentioned as cell functions are now presented.
