ABSTRACT
The particular choice of empty regime at the amputation point is a function of the position in the body of the animal and might result in the regeneration of either head or tail for certain cuts. The formation of gametes is represented in the hydraulic model by the progressive draining of the epigenetic landscape. The saddle points corresponding to the various individual organs emerge successively from the surface of the water, thus breaking the straight paths defining the main physiological functions. The global intensity of the metabolism decreases abruptly in these germinal cells shortly before or shortly after meiosis, and this leads to a contraction of the topological structure defined by the system. To understand organogenesis, the author must move up the scale of living beings, starting with the unicellular organisms like amoebae. It is essential to understand that every function corresponds to the catastrophic correction of a state of metabolic disequilibrium.
