Yes, that was exactly the point. Technology developed in imitation of a much more sophisticated and incompletely understood animal example, for which a more complete theory was developed. And that more complete theory eventually became sophisticated enough to comprehensively explain the biological artifact. (And in spite of that, we still keep birds around, because not everything of value about birds is captured by an aerodynamic analysis of a bird's wing. Obviously.)
