Compared to birds, we are poorly designed for the air. And yet we fly. Not by anatomy, but by mind. The origins of this paradox may lie far above the ground, in the trees. Early primates lived in a three-dimensional world of branches, an environment defined not by stability, but by uncertainty. Every surface had to be evaluated: its strength, its flexibility, its angle, its motion under load. To move through this world required continuous calculation. A leap from one branch to another is not simply a movement. It is a prediction. Distance, trajectory, compliance of the landing surface, grip at the moment of contact, the body as a projectile in space. In this setting, intelligence is not abstract. It is physical. The brain becomes a modeling system for forces. Torque, bal...
