About this title

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.

Ideal for readers of evolutionary biology, genetics, and philosophy of science who want a rigorous, theory-driven perspective on how definite variation can guide life’s progress.
