Description: This book challenges the long-held belief that species evolve gradually over time. The author, a prominent botanist, argues that species arise not through slow, incremental changes, but through sudden, distinct leaps known as "mutations." This idea, the "Mutation theory," stands in direct contrast to Darwin's theory of natural selection, which holds that species evolve through the gradual accumulation of small variations. The author carefully examines the evidence supporting Darwin's theory, finding it lacking in experimental support. He questions the reliance on breeders' observations, arguing that their practices are not designed for scientific inquiry and often fail to record the true origins of new varieties. He then presents his own experimental evidence, focusing on the evening primrose, *Oenothera Lamarckiana,* which he meticulously studied for years. He details a series of mutations that occurred in his cultures, demonstrating how new species can arise abruptly and remain stable. The book explores the nature of variability in plants, drawing a clear distinction between individual variation, which is continuous and influenced by the environment, and mutability, which involves sudden and distinct changes in the hereditary makeup of an organism. The author argues that only mutability can lead to the origin of new species. By examining the origin of new species through mutation, the author proposes a revolutionary approach to understanding the development of life on Earth. His work offers a new lens through which to view the processes of evolution and provides valuable insights into the nature of variation and the mechanisms of speciation.
