The confirmation lies in the fact that the modern brain RESPONDS to new requirements; it does not complexify or expand in anticipation of new requirements.

But in case you hadn’t noticed, I am proposing that God the designer designed a mechanism that enabled the cells of which all organs and organisms are made to carry out their own designing. Your vision of God doing a brain/skull/pelvis operation on the Moroccans is “pure theory” with no facts to support it. At least my theory has as support the known fact that the modern brain complexifies and/or expands (small scale) in response to new requirements.[/i]

I don’t know to what extent all the different brain sizes created new lifestyles and artefacts “over time” (i.e. after expansion, as opposed to them being the driving force for the expansion itself) before the new brain sizes came into being. Perhaps you’ve done the research or have time to do it. I have mentioned these as POSSIBLE CAUSES of brain expansion. But it is certainly true that after the initial expansion to sapiens size – whatever the cause – there was a long period of stasis before the new brain suddenly had to respond to new requirements by complexifying, expanding certain sections, and also discarding some cells which were no longer necessary. I don’t know how that supports your approach and not mine.
