Big brain evolution: Evidence of trading 300,000 years ago (Evolution)

dhw: When concepts appear is indeed the issue between us. All the evidence we have points to the conclusion that thought changes the brain – whether in complexity or in size. But once a concept has been realized (and the brain has complexified or enlarged), of course the s/s/c will have greater "thought capacity" – because it can build on existing, and now materialized concepts! The s/s/c learns from experience, and that is an ongoing process, but the concept always has to precede the implementation, and that is what causes expansion/complexification.

Yes, concept precedes implementation, but that in no way proves it is the reason the brain expanded. It is just your hypothesis.

DAVID: After all IQ varies from 60 to 200+, so a large part of the range must represent the brain's competence/ability to handle s/s/c thought. With this in mind advanced concepts require an advanced complexity in brain size and structure. Size first concepts second.

dhw: The competence of the brain to HANDLE thought is the whole point! If the thought is too complex for the existing brain to HANDLE, then the brain is required to make changes, i.e. complexify or expand. The concept creates the need for expansion (dualism). But you the dualist keep arguing that expansion creates the ability to conceive (materialism).

And you keep forgetting my theory that in life the only way original thought occurs is if the s/s/c is interfaced with the brain.

dhw: We are talking specifically about brain enlargement, and you insist that your God enlarged the pre-sapiens brain before it was able to come up with new concepts, i.e. the brain is the source of thought. And that is a complete contradiction of your dualistic belief that the s/s/c is the source of thought.

My concept of how brain and s/s/c relate: In life the s/s/c and the brain must work together. Your interpretation of my theory is totally incorrect.
