Paperback. Condizione: New. Print on Demand. This book delves into the fascinating world of plant variation, exploring the origins of new plant varieties and the role of both chance and human intervention in their creation. The author draws heavily on the observations and practices of horticulturists, comparing them to the theories of Darwin, and ultimately presenting an alternative perspective on the development of new species. The book dissects the concept of "selection," as it was understood in Darwin's time, and argues that while human intervention can refine and improve existing traits, it cannot create new ones. Instead, the author introduces the idea of "latent" and "semi-latent" characters, which are hidden traits within a species that can be brought to the forefront through chance mutations or specific cultivation techniques. This leads to the discussion of "intermediate races," or "eversporting varieties," which are highly variable plant forms resulting from the interaction of two contrasting characters. The book examines these concepts in detail, using examples from various plant species to illustrate the complexities of plant variation. It provides a detailed analysis of the statistical methods used to study plant variations, showcasing how these methods can be employed to understand the role of latent characters in the creation of new plant forms. By challenging the prevailing view of gradual evolution through natural selection, the author offers a fresh and intriguing perspective on the origin of species, suggesting that sudden mutations, rather than continuous variation, may be the driving force behind the diversity of the plant kingdom.
