Paperback. Zustand: New. Print on Demand. This book presents a convincing interrogation of the origins of species and varieties in the plant kingdom, tracing the development of the field of genetics. The author, a leading figure in the field of botany, argues against Darwin's theory of evolution by slow accumulation of slight fluctuations. Instead, the author argues that species and varieties have originated through sudden mutations, a theory that has only recently gained acceptance. The book provides an in-depth examination of the various types of variability, including fluctuating variability, progressive variability, and retrogressive variability. The author draws on historical evidence and his own experimental pedigree-cultures to support his theory of mutations. The research in this book has contributed to a deeper understanding of the processes of evolution and adaptation, making it a must-read for anyone interested in the history of life on Earth and the evolution of organisms.
