Paperback. Zustand: New. Print on Demand. This book examines the evolutionary history of a genus containing over 30,000 species of sea snails. Through exploration of the biological and physical factors that can influence evolution, the author discredits fixed species distinctions. Studying the vast range of variation within Nassa, the author argues that the observed patterns can only be understood by recognizing individuals as existing on a spectrum of variation. Delving into a wealth of natural history observations, the book expands on a growing body of evidence showing that species evolve in gradual, nearly imperceptible steps. Researchers interested in the evolution of species and those interested in the study of sea snails will find this book a compelling read.
