Preface

This book was written with a broad readership in mind. Students as well as working biologists in the fields of physiology, morphology, zoology, evolutionary biology, and ecology, especially those interested in or who are actively engaged in the area of comparative respiratory biology will particularly find it of significance. Scientists in the fields of Earth Sciences who are interested in how the physical world has interacted and influenced the biological one and therefore determined the development of life forms, states, and physiological processes will find the book interesting and hopefully stimulating. A section of the treatise deals with the origin, the dynamics, and the physicochemical properties of the respiratory gases and fluid media, with specific focus on molecular oxygen (O2). By designating O2 as “the molecule that made the world” and observing that “if water is the foundation of life, then oxygen is its engine,” Lane (2002) absolutely summed it up. Large-scale anoxia and hypoxia, especially in the oceans, is commonly cited as having been the foremost driver of mass extinctions as well as a long-term limiting factor of evolutionary radiation of life on the early Earth, particularly during the Cambrian. Insights into the mechanism(s) of the inauguration
