In 1972 Stephen Jay Gould took the scientific world by storm with his paper on punctuated equilibrium. Challenging a core assumption of Darwin's theory of evolution, it launched the controversial idea that the majority of species originates in geological moments (punctuations) and persists in stasis. Now, thirty-five years later, Punctuated Equilibrium offers his only book-length testament on a theory he fiercely promoted, repeatedly refined, and tirelessly defended.

The Explanation and Broader Meaning of Stasis Frequency Generality Causality Punctuation, the Origin of New Macroevolutionary Individuals, and Resulting Implications for Evolutionary Theory Trends The Speciational Reformulation of Macroevolution Ecological and Higher-Level Extensions Punctuation All the Way Up and Down? The Generalization and Broader Utility of Punctuated Equilibrium (in More Than a Metaphorical Sense) at Other Levels of Evolution, and for Other Disciplines In and Outside the Natural Sciences General Models for Punctuated Equilibrium Punctuational Change at Other Levels and Scales of Evolution A Preliminary Note on Homology and Analogy in the Conceptual Realm Punctuation Below the Species Level Punctuation Above the Species Level Punctuational Models in Other Disciplines: Towards a General Theory of Change Principles for a Choice of Examples Examples from the History of Human Artifacts and Cultures Examples from Human Institutions and Theories about the Natural World Two Concluding Examples, a General Statement, and a Coda Appendix: A Largely Sociological (and Fully Partisan) History of the Impact and Critique of Punctuated Equilibrium The Entrance of Punctuated Equilibrium into Common Language and General Culture An Episodic History of Punctuated Equilibrium Early Stages and Future Contexts Creationist Misappropriation of Punctuated Equilibrium Punctuated Equilibrium in Journalism and Textbooks The Personal Aspect of Professional Reaction The Case Ad Hominem against Punctuated Equilibrium An Interlude on Sources of Error The Wages of Jealousy The Descent to Nastiness The Most Unkindest Cut of All The Wisdom of Agassiz's and von Baer's Threefold History of Scientific Ideas A Coda on the Kindness and Generosity of Most Colleagues Notes Bibliography Illustration Credits Index
