The future of the human posture is in the spotlight. The 200-year-old locomotion paradigm can no longer resist the advancement of knowledge, yet 2,500 years of thinking on the place of verticalized human anatomy and its reflexive consciousness in the natural history of life and the Earth, is more relevant than ever.
This book retraces these reflections from pre-Socratic philosophers, focusing on the link between verticality and the most complex and consciously reflexive nervous system on the top rung of the ladder of living beings. The origin of animated forms, or animals, was considered metaphysical until the 19th century but reflection on their inception, from fertilization, paved the way for mathematics of infinitesimal geometry and dynamics. The simian filiation was inconceivable until Jean-Baptiste de Lamarck bridged the gap in 1802 with the locomotion postulate to explain the transition from quadrupedal to bipedal posture, sustained by the hypothesis of inheritance of acquired characteristics. This doctrine was overturned in 1987 by the discovery of the embryonic origins of the straightening - specific dynamics linked to neurogenesis - confirming the natural place of human verticality and nervous system complexity with its psychomotor and cognitive consequences.
Sapiens find themselves at the physical limit of the straightening while mechanisms of gametogenesis have never ceased in making neurogenesis exponentially more complex. Is the future exclusively terrestrial or does intrauterine hominization open up new perspectives for space exploration? Posturologists, occlusodontics, osteopaths, cognisciences - all anthropological sciences exposed to human verticality are concerned with this discovery, which allows Sapiens to face their natural destiny
