The fact that our brain changes as a REACTION to any and all physical and mental and emotional demands made on it, and even produces a few new cells in doing so (although it has stopped expanding overall) seems to me to provide sufficient evidence for my theory to be regarded as feasible. There is no evidence that one fine night God stepped in to perform an operation on a group of Moroccan brains, skulls and pelvises.

> > dhw: [i]We have covered the stasis argument a hundred times. Once the pre-sapiens brain had expanded, there were no major new ideas until about 280,000 years had passed. There were similar periods of stasis after earlier expansions. It appears that our brains began to change again about 35,000 years ago, when there was a sudden burst of innovative activity. That fits in with my theory. The brain REACTS to new requirements, not in anticipation of them.[/i]

> > 
> > dhw: But it has been demonstrated, and even stated by yourself as bolded above, that the brain REACTS to new requirements. There is no evidence that it expands or complexifies in direct anticipation of new thoughts. This should not be confused with the fact that once the brain has expanded, the dualist’s soul may continue to come up with new thoughts which will in turn require new complexifications and, in pre-sapiens times, new expansions.

> > DAVID: [i]Your interpretation of how a brain reacts does not include any evidence of enlargement. I have bolded my comment about errors. Advances in evolution are so complex only a thinking biological engineer can create them. The brain has never been shown to enlarge itself to the degree seen in fossils.[/i]
> > 
> > dhw:  Once more: Nobody knows how the brain expanded, and our brain has stopped expanding overall, which is why we have to theorize. See above for the rest of the argument.
