All of us animals used to live in the same simple way – finding different ways to survive. But early humans certainly advanced way beyond their fellow animals with their invention of tools, weapons, use of fire etc, which were giant steps at the time, and required additional brain capacity (= expansion). We don’t know the exact cause of each expansion, or the final one, which was that of sapiens. But all brains, including ours, then went through a period of stasis, as life went on in the same relatively “simple way”. But then, for some unknown reason, sapiens came up with a veritable explosion of new ideas, and in order for these to be implemented, the brain did not expand with more cells, but vastly increased its ability to complexify - so much so that it actually shrank. A modern example is the way illiterate women’s brains complexified when they learned to read. Do you believe their brains complexified IN ANTICIPATION of their learning to read?

> Early sapiens ideation was small and you want to explode it. Compare your current lifestyle using a computer, translating languages in fully using your brain, which 315,000 years ago came fully prepared for that present use. And complexification sitting there, ready to help and helping those Italian ladies become literate.
