Brain complexity: more important than size (Introduction)

DAVID: Yes it is as yours it totally backward to the evidence we have in sapiens knowledge and skull shrinkage.

dhw: You are clutching at the same straw that has already been screwed up and thrown away. Shrinkage has been explained as above. Do you or do you not accept the findings of modern science that the brain changes in response to concepts, and not in anticipation of them?

You have not explained why each stage of hominin starts 200cc larger, composed primarily of frontal and prefrontal cortical growth, more neurons, more connections, and then subsequent to that growth the artifacts improve and are more complex. It is that part of the brain, used by the soul, which thinks. Size first, use second by evidence in history. You insist that an urgency for implementation forces the size jump (evolutionary mechanism unknown). But history tells us the sapiens brain arrived 300,000 years ago, with most implementation in the past 10,000 years. If it was required by necessity, what took so long (290,000 years)? My answer, sapiens had to learn to use the new capacity. And with complexificiation the brain and skull shrunk a little. This tells us it was an early development in evolution in early hominins, because we see no tiny enlargements, but 200 cc jumps in size, with each stage not gradually enlarging, but complexifying at the same size achieved when the new hominin stage appeared. Since I believe God speciates, He caused the necessary enlargements to occur.
