Homoiothermism The Origin Of Warm Blooded Vertebrates PDF Download

Excerpt from Homoiothermism: The Origin of Warm-Blooded Vertebrates The homoiothermic condition is an adaptation for living a life under constant conditions in a highly vari able environment. It has enabled birds and mammals to become dominant in the land habitats on the earth. Some homoiotherms, like the whales and sea birds, have been able to return to the home of their remote ancestors and have again attained a considerable degree of success in the ocean. This book is concerned with the physiological and eco logical aspects of the evolution of poikilothermic into homoiothermic animals. In it we attempt to discuss evi dence for the origin of homoiotherms, temperature regu lation, the factors influencing rate of metabolism and growth, and other matters which relate to the adjust ments associated with evolution from erratic, more or less intermittent, living to uniform, constant living.
