Brain expansion (Evolution)

DAVID: I'll stick with history. Bigger brains, better artifacts is all we know.

dhw: You don’t stick with history. Your invention is described above.[Now please see below!] The existence of bigger brains and better artefacts does not in any way contradict my theory.

DAVID: All we know is bigger brains are found with improved artifacts.

dhw: So how does that support your theory that your God stepped in one night and expanded the brains, skulls and pelvises of the Moroccans? And how does it invalidate the theory that the effort of designing and producing improved artefacts may have been one of the possible causes of brain expansion, just as we know through modern science that the effort of performing new tasks causes the brain to change?

Same old discussion. All we know is our brain shrank with complexification. The opposite finding of big-brained sapiens in Morocco without new artifacts denies the idea of implementation caused expansion.
