These constructions are not fixed; they are living structures that self-assemble in real-time over rough and unstable terrain, including bridges, ramps, and bivouacs. This ability to form and maintain adaptive structures—such as clusters of honeybees changing shape in response to wind—demonstrates a built-in control mechanism that ensures system function despite environmental instability. The successful function of these large-scale biological structures arises from the principle that dynamic interactions among simple individuals create systems capable of highly complex tasks that the organisms alone cannot perform. ...
