Classic Texts: Ridley Website

Mark Ridley's Evolution has become the premier undergraduate text in the study of evolution. Readable and stimulating, yet well balanced and in-depth, this text tells the story of evolution, from the history of the study to the most recent developments in evolutionary theory.
The third edition of this successful textbook features updates and extensive new coverage. The sections on adaptation and diversity have been reorganized for improved clarity and flow, and a completely updated section on the evolution of sex and the inclusion of more plant examples have all helped to shape this new edition. Evolution also features strong, balanced coverage of population genetics, and scores of new applied plant and animal examples make this edition even more accessible and engaging.

Chapter 4: Natural Selection and Variation

Chapter 13: Species Concepts and Intraspecific Variation

Chapter 20: Evolutionary Developmental Biology

Classic Texts
The Evolution website provides you with twenty classic texts from the history of evolutionary biology. While there has to be an arbitrary element in the choice of papers, we have aimed to include timeless classics: some of them are still the works that dominate modern discussions, others remain as implicit towering structures behind the activities of the 21st Century. All, however, are superb scientific papers, providing all sorts of intellectual pleasure for the reader.
