Not one his best books I find but still good discussions of the effects and results of Darwin's efforts and all that has come of them. Worth reading and like all his work written to be easily read.
Steven Gould was one of the better writers on natural history. These essays which first appeared in the magazine Natural History give an indication on how well he was able to articulate the science of evolution for the non-scientist.
Originally received this used book here at PBS. This book is paperback size (unlike the rest of Gould's books). The guy who had it before me must have used it in a college class, as there is highlighting throughout. Five star book: learn evolution is a bush not a ladder, how a clam can mount a fish on its rear end, the Irish Elk, the continental drift theory, abd talks about why we should not name races and the politics that run the world. Pretty heady material, worth the read if you are a Gould fan, love Natural History or are curious about Evolutionary Theories. The picture (P105) of the clam with the fish attached is worth the free book.
