In a brilliant move, Belknap Press has posthumously extracted a single chapter—number nine—from The Structure of Evolutionary Theory and published it as a stand-alone book, Punctuated Equilibrium. It's a testimony to the density of the work that a single chapter is sufficient to make a complete and thorough book on its own. The publisher has simply cut away the first 745 pages and the last 318 of the original. What's left is a text that is sharply focused on the theory for which Gould and his colleague Niles Eldredge are best known. It works beautifully...Gould documents the evidence for his controversial theory and its implications in impressive detail. The book is rich in data and dense in theory, representing a powerful summary of the arguments...Gould, in his typically immodest way, suggested that the theory of punctuated equilibrium could tell us about much more than the rate of evolution, and that it pointed to a whole new hierarchy of evolutionary phenomena. He proposed that the discipline of evolutionary biology should be expanded to accommodate new ideas that he, in part, had established. Inevitably that raised hackles. Yet critics and proponents must read his ideas. This sharp, detailed extract from his last great work offers an essential summary.
