Description: When Niles Eldredge and Stephen Jay Gould, two of the world's leading evolutionary theorists, proposed a bold new theory of evolution - the theory of "punctuated equilibria" - they stood the standard interpretation of Darwin on its head. They also ignited a furious debate about the true nature of evolution.

On the one side are the geneticists. They contend that evolution proceeds slowly but surely, driven by competition among organisms to transmit their genes from generation to generation. On the other are the paleontologists, like Eldredge and Gould, who show in the fossil record that in fact evolution proceeds only sporadically. Long periods of no change - equilibria - are "punctuated" by episodes of rapid evolutionary activity.

According to the paleontologists, this pattern shows that evolution is driven far more by environmental forces than by genetic competition.

How can the prevailing views on evolution be so different? In Reinventing Darwin, Niles Eldredge offers a spirited account of the dispute and an impressive case for the paleontologists' side of the story. With the mastery that only a leading contributor to the debate can provide, he charts the course of theory from Darwin's day to the present and explores the fundamental mysteries and crucial questions that underlie the current quarrels.

Is evolution fired by a gentle and persistent motor and fueled by the survival instincts of "selfish genes"? Or does it proceed in fits and starts, as the fossil record seems to show? What is the role of environmental changes such as habitat destruction and of cataclysmic events like meteor impacts? Are most species inherently stable, changing only very little until they succumb to extinction? Or are species highly adaptable, changing all the time?

Eldredge sorts through the major findings and interpretations and presents a lively introduction to the leading edge of evolutionary theory today. Reinventing Darwin offers a rare insider's view of the sometimes contentious, but always stimulating work of scientific inquiry.
