The various reptilian relationships of Archaeopteryx are reviewed. Crocodilian and theropod ancestry for Archaeopteryx and therefore birds is rejected because of the specialized morphology of both these taxa. In contrast the known morphology of certain thecodonts provides the necessary features from which the primitive avian morphology of Archaeopteryx can be derived. The origin of flight in birds is discussed within the context of the ecological setting of the Solnhofen environment. The primitive level of the flight morphology of Archaeopteryx is used to interpret the flight capabilities of these early birds.
