Synopsis
Discover how heredity shapes evolution with a bold new view on variation.
This edition presents August Weismann’s theory of Germinal Selection as a necessary complement to natural selection. It argues that variation is not random noise, but influenced by life conditions and germ-plasm dynamics, guiding change in a definite direction when selection acts. The discussion situates germinal units and biophores at the heart of how organisms adapt and how new traits emerge across generations.
In clear, accessible language, the work explains why development and heredity cannot be fully understood from outward factors alone. It contrasts old ideas about purely accidental variation with a model that emphasizes internal mechanisms and selective pressures that shape evolution over time. The author also addresses critics and the role of imagination and theory in scientific progress, offering a framework for thinking about how useful variation arises and persists.- Learn how the book reframes the relationship between selection and variation.
- See how internal germinal factors might steer evolutionary change.
- Explore core ideas about heredity, development, and the limits of mechanical explanations.
- Understand the balance between personal selection and germinal processes in shaping species.

On Germinal Selection as a Source of Definite Variation (Classic Reprint)
Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 5 out of 5 stars
Paperback. Condition: New. Print on Demand. This book concerns evolutionary biology and is particularly concerned with the theory of natural selection. The author argues that the theory, as advanced by Darwin and Wallace, is insufficient on its own to explain the development of complex life forms and that another factor must be involved. The author examines the Lamarckian and Weismannian theories of inheritance and provides an alternative theory which he terms "germinal selection." The author claims that this new theory reconciles Lamarckian and Weismannian principles, thereby providing a more comprehensive explanation of evolution. This idea, which was first introduced in an address at the International Congress of Zoologists, was well-received and is considered a significant contribution to the field of evolutionary biology. The book will be of interest to students and scholars of evolutionary biology, genetics, and heredity.
