Just as you said, insanity, since it goes against the idea of some who do not want to consider Homo Sapiens as a biological species that became what he is when he left the forest and went into the savanna and started running after his hunting prey. He became a long-distance fast bipedal runner and that changed his whole body and future. That happened in Black Africa 300,000 years ago. Language was the collateral consequence of the mutations he needed to become the runner I just said. And with language he could start the mental trip to a mind and conceptualization and along that way he found some durable media on which he could continue inscribing symbols, signs, and drawings he had started long before but the durable media were not yet at his disposal. And what’s more to be able to follow this track he had to develop a strategy to expand his species and migrate. And here we find the fact that Homo Sapiens WOMEN were dominant, had to be, otherwise, in 16 years of procreative life, they would never have been able to bring at least three individuals to full 13-year long procreative life.
If you do not understand that, I would have to say sanity is insane, sir.
