Origin of natural intelligence and conscience in humans and animals

On the base of laws of physics, the natural evolution is a sort of intelligent machine that continuously solves problems and gives solutions. The physical variable at the basis of the biomimetic solutions is the improvement of the synergies in multi-element system that leads to more efficient conditions. The final system is able to produce the same output with minor expenses, or a more complex one with the same cost. This works for living structures and for related social dynamics.
