The Big Bang of Human Evolution

THE BIG BANG OF HUMAN EVOLUTION The hominid promontory grew at an accelerating pace until it reached its present size of 1500cc about 200,000 historic period ago. Yet uniquely gay abilities such the invention of extremely sophisticated standardized multi- part tools, tailored clothes, art, religious popular opinion and perhaps even manner of speaking are thought to develop emerged quite rapidly around 40,000 years ago ? a sudden explosion of valet mental abilities and culture that is sometimes called the big have sex. If the brain reached its full human potential ? or at least size ? 200,000 years ago wherefore did it remain idle for 150,000 years? Most scholars are convinced that the big bang occurred because of some unknown genetic alteration in brain structure. For instance, the archeologist Steve Mithen has just written a book in which he claims that before the big bang there were three antithetic brain modules in the human brain that were specialized for social or machiavellian experience, for mechanical intelligence or tool use, and for natural accounting (a propensity to classify). These three modules remained isolated from each other entirely around 50,000 years ago some genetic flip-flop in the brain suddenly allowed them to communicate with each other, resulting in the enormous flexibility and versatility of human consciousness.

I disagree with Mithen expert suggestion and offer a very different rootage to the problem. (This is not incompatible with Mithens view but its a different idea). I suggest that the so-called big bang occurred because real critical environmental triggers acted on a brain that had already become big for some other reason and was because pre-adapted for those cultural innovations that make us uniquely human. (One of the key pre adaptations creation mirror neurons.) Inventions like tool use, art, math and even aspects of language may have been invented accidentally in one institutionalize and then spread very quickly given the human brains amazing capacity for imitation...
