Excerpt from The Mutation Theory, Vol. 2: Experiments and Observations on the Origin of Species in the Vegetable Kingdom
Darwin based his theory of selection, in great part, on the well-known horticultural principle that new varieties arc obtained by seeking for small deviations with subsequent isolation and selection. Variations which at their first appearance almost escape observation can be worked up by the skill of the gardener; in doing so variability is seen to increase, and in favorable cases, very rapidly. In this way a new form arises, which answers the purposes and rewards the labors of the breeder.
We have all heard how beautiful double varieties have resulted from the appearance of single flowers in which only one stamen and this often only partially was transformed into a petal.
In the first volume we dealt with this practice more than once, and pointed out how liable it is to give rise to misunderstanding when applied to the elucidation of the problem of specific differentiation (Vol. I, §23, pp. 176-185). The object of the present Part is to collate the relevant data and to show what light they throw on this all-important problem. Of course we can only go so far as the incomplete and scanty character of the material will allow.

Paperback. Condición: 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. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Nº de ref. del artículo: 9781330679340_0
