More recent research indicates that fish with jaws had far less to do with the extinction of the ostracoderms than ...
In practice, fish anatomy and physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in the living fish.
