> > DAVID: [i]You are trying to disarm the impression that big brain, unused, brings to anyone who thinks. "All dressed up and no place to go" is an obvious thought. Or, the earliest sapiens built a rocket for a moon launch, 315,000 years ago and just finally used it 50 years ago. This analogy fits as you wildly talk all around the obvious impression.[/i]
> > 
> > dhw: you say your God expanded the brain 315,000 years ago, but sapiens did nothing with it. Why did he expand it then if nothing was done with it for 280,000+ years? You simply refuse to consider the possibility that the pre-sapiens brain expanded 315,000 years ago as a RESULT of some new requirement 
> 
> What new requirement? Each next stage of human development starting at Lucy (or similar) grew 200 cc average until it stopped at sapiens with 1,200+cc alj due to frontal and prefrontal enlargement. Very full use of big brains started only in the past 10,000+ years when we left  caves. Each anticipatory enlargement forms the same pattern since Lucy.  Are you proposing new chance small requirements each time? Doesn't the pattern fit a plan? I chose God's agency.
> >  
> > DAVID: [i]You constantly stumble around not finding a natural driving cause and history tells us there was no need for such a big brain, but not any sort of driving force is known as you try to worm around in your explanations.[/i]
> > 
> > dhw: History does not know what caused the brain to expand. All we know is the brain changes when it meets new requirements. But I doubt if there are many historians who would tell you that an unknown power operated on a few brains 315,000 years ago, so that the brain-owners could learn how to use their brains by achieving nothing until 285,000+ years later.'
