Print on Demand. This book challenges the scientific consensus on the fundamental principles of evolution. The author, an acclaimed geneticist, reveals new insights into the role of mutations as a mechanism for evolutionary change. The book presents a groundbreaking theory that sheds light on the origin and behaviour of certain plant and animal species with an extra chromosome, drawing from extensive research conducted with the evening primrose plant, Oenothera. It explores the concept of mutations as spontaneous alterations in the genetic material, leading to new heritable traits. The author's findings on duplicate factor mutations, chromosome duplication, and the impact of these changes on heredity and evolution challenge traditional views. The book offers a comprehensive analysis of mutation phenomena in plants and animals, providing a foundation for future research and a deeper understanding of evolutionary processes. Its insights will resonate with biologists, geneticists, and anyone interested in the mechanisms that shape the diversity of life on Earth. 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.…

- Evolutionary Biology
If we go but a step further, and assume that these variations are followed by others in the same population with elimination of some steps by selection or if we assume the immediate origin of new specific types through single mutations, and their gradual spread from the centre of origin, then we are using the mutation theory of de Vries as it is widely applied at the present time. Darwin's objections to sudden and considerable deviations of structure as material for evolution, were based largely upon his observations of wide saltations and monstrosities. They included the well-known argument of swamping through crossing, which has since been negatived by the Mendelian discoveries.

Reseña del editor
The aim in producing these Chapters was to make them a contribution to current problems of genetics and evolution. The earlier Chapters deal with some of the more recent contributions to genetics, both in plants and animals, particularly as regards questions relating to mutation. This involved comparisons of the mutation phenomena in (Enothera, Drosophila and various other forms. The importance and significance of parallel mutations has also been emphasized. Owing to circumstances for which the writer is in no way responsible it has been necessary largely to curtail the treatment and to omit almost entirely a discussion of the important cytological results concerning mutation in plants and animals which have been attained since my Mutation Factor in Evolution was published in 1915.
In Chapters VI and VII are cited from the recent literature numerous cases of mutations in plants and animals, and also a selection from the great number of presumptive mutations described as new varieties or species in the systematic journals. The history and geographic distribution of these is often of the greatest interest from the point of view of their probable origin, and the mutation theory has undoubtedly been of great value in interpreting such variations both in wild and cultivated forms.
In the last five Chapters more general evolutionary problems have been considered. Some of the corollaries of the mutation theory as regards organic structure, and some of its limitations, have been pointed out. In particular, the contrasts between mutational and organismal characters as regards the structure and distribution of organisms, their relation to recapitulation and such problems as those of adaptation, alternation of generations and inheritance of acquired characters, have been considered in so far as space permitted. The aim has been to show that despite the importance of mutations or germinal changes in evolution, they have definite limitations; and that large fields of organic phenomena will require the neo-Lamarckian factor for their adequate explanation. This is really applying the point of view of Darwin to the modern advances in our knowledge of variation and of the structure, ontogeny, inheritance, distribution, and relationships of organisms.
