• Introduction.Part I. The rise of organic selection: thinking plasticity ecologically1. Framing the issue from the viewpoint of natural selection. The confusing birth of organic selection in the pre-Mendelian era.2. The eclipse of organic selection. The case-study of French-speaking post-Lamarckian biology.3. The experimental turn, from plastic change to speciation.Conclusion of Part IPart II. Waddington and Schmalhausen: thinking plasticity developmentallyIntroduction of Part II4. ‘Autonomization’, ‘canalization’ and ‘genetic assimilation’. Towards a developmental perspective on the relationship between adaptability and adaptation. 5. A problematic issue: the creativity of the developmental process.6. An overlooked revolution? Creativity in the evolutionary building of a new reaction norm.Conclusion of Part IIPart III. (dis?)Integration into the Modern Synthesis: thinking plasticiy geneticallyIntroduction of Part III7. The Baldwin effect: “de-ecologizing” organic selection.8. Re-working Waddingtonian concepts within quantitative genetics.9. The complex fate of Waddingtonian concepts in the subsequent history of the Modern Synthesis.Conclusion of Part IIIGeneral Conclusion.
