Question

Explain the evolution of 'exchange control'.

Answer 1

The field of comparative respiratory biology is progressing rapidly. Superior analytical methods and more novel approaches are moving the scope to fascinating horizons. The inventiveness continues to confound students as well as specialists in the area. The expansion of the information base is empowering investigators to better synthesize, rationalize, reconcile, redefine, consolidate and verify some of the earlier anecdotal views and inferences. Occasional reviews of the advances help outline new grounds, formulate new concepts and evoke further inquiry. Moreover, such surveys of the literature should promote communication among investigators, preventing costly duplication of effort.
