Development of wings appears to be a remote and simple process

Winged insects, therefore, emerge suddenly according to fossil evidence with already established physiological structures. A close examination of the insect wings reveals that muscles are not directly attached to the wing surface but rather coordinate the flight by exerting force on the thorax. The wings are typically connected to the trachea, neurons, and the circulatory system (Engel, 2005). This is perhaps an evolutionary outcome that enabled the wing tissues to be supplied with metabolites, oxygen, and signals from the general body systems always independent of the muscular contractions for flight.

However, the wings themselves are not complex but simple structures that evolved for easy and faster flying. The various maneuvers made by the insect in the air at different speeds are possible through the simple body with not much weight. This also allowed a quick generation of the sleek forces required to lift the wing for flight. The wings, therefore, act as perfect aerofoils capable of interpreting the dynamic muscular forces and torque resulting from the forces of inertia as the insect flies in different directions in the air (Hall, 1998).

As much as the development of wings appears to be a remote and simple process, their level of structural modifications associated with its physiological systems throughout evolutionary history has resulted in a well-designed flight regime. The evolution of wings from body structures that were previously existing is therefore viable given the energy and regulation requirements that a flying insect must have (Hutchins, 2006). The muscles can propel the lean insect in the direction of motion when wings are folded properly to assume the aerofoil symmetry. This then allows the insect to cut across the frictional drag in the air sufficiently to take off the ground while still in support of its weight.
