This book makes me sick! Its an insult to Gould's life and career. This is just one portion of a much larger book! Gould's reasoning is very dialectical. The first half of "The Sturcture of Evolutionary Theory" is on the history of Evolutionary biology. Cutting that out of the book is just disgusting. He never would have wanted this or okay'd it. I understand that the price of The Structure is high, and there needs to be a cheaper paperback version, but this is not the way. If need be, cut the book into two volumes as a paperback, and drop the price. Don't gut his book and sell some abridged version. If you want to read this book, buy the structure! In 1972 Stephen Jay Gould Took The Scientific World By Storm With His Paper On Punctuated Equilibrium, Written With Niles Eldredge. Challenging A Core Assumption Of Darwin's Theory Of Evolution, It Launched The Career Of One Of The Most Influential Evolutionary Biologists Of Our Time - Perhaps The Best Known Since Darwin. Now, Thirty-five Years Later, And Five Years After His Untimely Death, Punctuated Equilibrium (originally Published As The Central Chapter Of Gould's Masterwork, The Structure Of Evolutionary Theory) Offers His Only Book-length Testament On An Idea He Fiercely Promoted, Repeatedly Refined, And Tirelessly Defended. Punctuated Equilibrium Holds That The Great Majority Of Species Originate In Geological Moments (punctuations) And Persist In Stasis. The Idea Was Hotly Debated Because It Forced Biologists To Rethink Entrenched Ideas About Evolutionary Patterns And Processes. But As Gould Shows Here In His Typically Exhaustive Coverage, The Idea Has Become The Foundation Of A New View Of Hierarchical Selection And Macroevolution.--jacket. 1.

Stephen Jay Gould. Originally Published As The Central Chapter Of Gould's Masterwork, The Structure Of Evolutionary Theory--p. [4] Of Cover. Includes Bibliographical References (p. 362-381) And Index. In 1972 Stephen Jay Gould took the scientific world by storm with his paper on punctuated equilibrium, written with Niles Eldredge. Challenging a core assumption of Darwin's theory of evolution, it launched the career of one of the most influential evolutionary biologists of our time--perhaps the best known since Darwin. Now, thirty-five years later, and five years after his untimely death, Punctuated Equilibrium (originally published as the central chapter of Gould's masterwork, The Structure of Evolutionary Theory ) offers his only book-length testament on an idea he fiercely promoted, repeatedly refined, and tirelessly defended. Punctuated equilibrium holds that the great majority of species originate in geological moments (punctuations) and persist in stasis. The idea was hotly debated because it forced biologists to rethink entrenched ideas about evolutionary patterns and processes. But as Gould shows here in his typically exhaustive coverage, the idea has become the foundation of a new view of hierarchical selection and macroevolution. What emerges strikingly from this book is that punctuated equilibrium represents a much broader paradigm about the nature of change--a worldview that may be judged as a distinctive and important movement within recent intellectual history. Indeed we may now be living within a punctuation, and our awareness of what this means may be the enduring legacy of one of America's best-loved scientists. Originally published as the central chapter in the late author's critically acclaimed study, The Structure of Evolutionary Theory, a critical challenge to a core tenet of Darwin's theory of evolution explores the nature of biological change and its influence on evolutionary patterns and processes.
