Paperback. Condición: New. Print on Demand. This book identifies the "primary freshwater stock", an enigmatic group of similar animals found in freshwater environments worldwide. The author examines the morphological and paleontological evidence to suggest these animals once existed in the ocean, but some factor caused them to move to and remain in freshwater habitats. The author also discusses the possible reasons for this change, proposing that it may have been due to an alteration in the chemical composition of the ocean that favored some species while harming others and led to the development of entirely new marine groups. The book is a valuable resource for understanding the evolution and distribution of freshwater faunas and the dynamic relationship between marine and freshwater ecosystems.
