The evolution of human cognitive abilities, despite intensive sociological, psychoanalytic and neurobiological investigations, is poorly understood. The basic events of this evolution: progressive language development, technologization, increased learning aptitude, remain a field of speculations without coherent and consistent explanations. In the recent manuscript, a production of artefacts as a general pre-condition of human being is highlighted, and a key role they played by reshaping of neuro-physiological functions is factually substantiated.
