直到距今约250万年前，人类才从哺乳动物中脱颖而出，在大脑的前额区域进

It wasn't until about 2.5 million years ago that humans emerged from mammals and evolved a "new cortex" in the forehead region of the brain. This new cortex didn't really take shape until 70,000 to 200,000 years ago, and became an unparalleled brain area. It allowed us to produce language, create art, develop technology, and build civilization. From then on, it has occupied an absolute advantage in survival on this planet. Humans are obsessed with their own unique intellect, so this new brain area is called the "intellectual brain". Of course, some people like to call it the rational brain or thinking brain.

It wasn't until about 2.5 million years ago that humans emerged from mammals and evolved the "new cortical layer" in the preamined regions of the brain. This new cortical layer didn't really take shape until 70,000 to 200,000 years ago, becoming an unparalleled brain region that allows us to produce language, create art, develop science and technology, build civilization, and from then on occupy an absolute survival advantage on this planet. Humans are addicted to their own unique reason, so this new brain region is called "rational brain", of course, some people like to call it rational brain or thinking brain

It was only about 2.5 million years ago that humans emerged from mammals and evolved a "neocortex" in the prefrontal region of the brain. This neocortex didn't really take shape until 70000-200000 years ago. It has become an unparalleled brain area. It allows us to produce language, create art, develop science and technology, and build civilization. From then on, it has occupied an absolute survival advantage on this planet.
