According to palaeogenetic analyses, the earliest Homo sapiens groups began to separate from one another in Africa around 150,000 years ago, and did so for decades. Due to a lack of selection, none of their brains have changed structural-ly in the same way since then. From this we can deduce something monstrous: The subsequent breathtaking development of culture and civilization of man-kind, its incessant higher development of cognitive levels, indeed its constant acceleration, was accomplished by means of a cerebrum that has always re-mained the same; phenotypes of individually high aptitude do not change this. In addition, paradoxically: The human brain does not differ substantially from the chimpanzee brain in terms of architectonics and neurophysiology; only the proportion of the non-specific association cortex has increased in humans by up to an immense 80%. This is an absolute novelty in the biological evolution of higher mammals: without any further organ and brain adaptation through muta-tions, only Homo sapiens is able to develop cognition continuously in creative stages. The analysis of its intracortical processes of cognitive optimization sug-gests the following hypothesis: Primarily the complex process of an exponential-ly increasing number of neuronal patterns - not a specially interconnected net-work - must generate a leap in quality, namely from the order states of procedur-al self-regulation to a contrary system of neuronal autonomy. It is only through this additional neural system - experienced as the control dominance of 'being conscious' - that the thinking potential for unlimited creative development is opened up. - A leap in autonomy compared to the animal consequently consti-tutes the hitherto misunderstood nature of the human being.
