For a generation, Eldredge, in collaboration with Stephen J. Gould, has attempted to erode Darwin's 'natural selection' mechanism of evolution. Instead of gradual, incremental change, they urge evolution as progressing in fits and starts. The idea is indirectly supported by the imperfect sequence of the fossil record, a point Darwin conceded in Origin of Species. Eldredge uses the remainder of this book to explain why 'natural selection' should be replaced by 'punctuated equilibrium' - it follows the pattern of history. The pattern is that a traditional idea replaced by more innovative concepts. The key example here is the replacement of gradualism in geology replaced by the more determined action of continental drift. Eldredge wants to replace Darwin's form of 'gradualism' in evolution with a Wegenerian concept in biology, punctuated equilibrium. This will gain Eldredge [and, one assumes, Gould] a stature in the history of science equaling Wegener's.
Daniel C. Dennett's DARWIN'S DANGEROUS IDEA offers a penetrating analysis of the punctuation idea. Illustrating the fallacies of the thesis, failing to provide a scale for measuring rate of species change, for example, Dennett's critique should have swept away any vestige of support for the idea. The 'UltraDarwinists' use molecular genetics to reinforce Darwin's original concept. While earth's history has experienced episodes of rapid change [a 10 km bolide provides an earthshaking [sorry!] environmental pulse], such events are not the mechanism of evolution.
Eldredge's own example of the Cecropia tree, a continuing theme through this book, is a perfect example of why Dawkins is right and Eldredge wrong. Cecropia's forebears adapted to the impact of increasing hurricane frequency due to the closure of the Panamanian isthmus. Eldredge calls Cecropia's emission of dormant seed pods 'cheating'. Yet that's exactly what Dawkins calls adaptation to environment. How rapidly did Cecropia 'learn' this trick? Where did it learn it? Clearly, those trees whose genes contributed to seed dormancy survived to enhance the talent in later generations. Why Eldredge fails to examine that aspect is a mystery, since it is evolution's method.
Recommendations about this book don't come easy. The dispute over 'punctuated equilibria' has gone on too long. Readers should be aware of Eldredge's views [and cheap rhetoric], but learn why he's wrong. Read this book, but don't buy it. Rush over to the Dennett page and pick up Darwin's Dangerous Idea, a book that deserves shelf space in anyone's library.
His tone is grand and plodding even avuncular through much of the book as befits the scope of a paleontologist of his stature, but with it he opens the way for more of us to keep up with him. This is definitely an accessible book. Yet do not miss the important gems of theory that he brings to the dialogue to evolve our understanding of evolution.
