Brain expansion

dhw: You have agreed that the ability for complexification was present in all early brains, and enlargement is enlargement, no matter which section of the brain is enlarged! Are you now saying that your God had to specially design all the cells that were added to earlier cortices and give them a special new ability for complexification?

DAVID: Of course.

dhw: But I thought you agreed that earlier brain cells already had the autonomous ability to complexify. So when God operated on all these sleeping homos, he added the new cortex cells to the old ones, and separately designed the same ability to complexify as that of the existing cortex cells. Wouldn’t it have been a lot simpler if he’d just given all the complexifying cells the ability to add to their number when they needed to?

Remember He specifically did in the hippocampus. If that ability is not elsewhere, that was His choice and answers your question.

DAVID: And you have offered no answer for the pelvic problem as before.

dhw: I asked about special designs for the brain other than the mechanisms for complexification and enlargement. It seems that you can’t think of any, and so you are trying to change the subject, which is the dodging tactic you keep using during our discussions of your illogical theories of evolution. You know my theory concerning the “pelvic problem”, which is precisely the same as my theory about all the problems posed to all species by changing conditions: intelligent cell communities learn to adapt. No doubt there would have been many instances of death in childbirth until those pelvises which adapted to the new requirements became the norm.

DAVID: Or in my view, God arranged it so new heads fit into new sized brains all at once, without all those messy deaths you prescribe. God's designs are gentler than your natural approach.

dhw: I have given you the same answer I gave you before, but if you prefer your own theory that your God preprogrammed bigger heads and pelvises 3.8 billion years ago, or performed operations on all those women’s pelvises, that’s fine. Death in childbirth wasn’t all that uncommon in historic times, so it’s perfectly conceivable that such a problem would have caused more deaths in pre-historic times.

You are very uncaring for our ancestors.
