This edition of "On the Origin of Species" is invaluable to anyone who has been suffering without Darwin's most important work, or getting by with only a stripped-down version. The text is the first edition of the six editions Darwin oversaw in his lifetime. It's the version scientists now regard as the most powerful and passionate statement of Darwin's views. But besides the full (unabridged) "Origin," this large-format book is replete with other materials. The word "sumptuous" comes to mind. There are hundreds of amazing illustrations, maps and diagrams, many in full color. Also included are scores of substantial excerpts from other works by Darwin and correspondence between him and his contemporaries. This makes the book a treasure to have, because it is so incredibly rich in contextual materials.
For instance, pictures of T.H. Huxley are included along with Huxley's letter to Darwin, where Huxley asserted his (not altogether unconditional) support for Darwin's argument and added that he was sharpening his claws and beak in readiness - that is, to help defend Darwin from his opponents. I was also delighted with the many beautiful photographs taken in the Galapagos Islands and of life forms found there, to say nothing of the pictures of Darwin, his family, colleagues and adversaries that are interspersed throughout the book, and Darwin's own drawings, the pictures of Darwin's home near Downe, his desk, models and a detailed diagram of the H.M.S. Beagle, and so on. There is also a chronology of Darwin's life to 1864. Reading this, you are getting far more than one book: the many excerpts from Darwin's earlier and later writings, and all the illustrations and other materials, provide considerable historical context for the "Origin," its development and reception, making this almost certainly the definitive edition.
If you have never read Darwin's masterpiece, this book is a first-class reason to do so. His prose is elegant - even, at times, eloquent. The argument unfolds logically and clearly. Darwin was an utterly unpretentious English gentleman, after all, who lived during the Victorian era; he was, and remains, a highly agreeable companion. (If you enjoy travel literature, Darwin's earlier "Voyage of the Beagle" is also highly readable and fascinating. It sold well in his lifetime and reads almost like an adventure story. Many excerpts from "Voyage" appear in the book under review. They may tempt you to read the other book.) "On the Origin of Species" was written to be read by anyone - it is not merely for scientists or experts. Small wonder that the first edition sold out the same day it was released.
One of the most striking things about the "Origin" is how careful, even cautious, Darwin is in drawing inferences from the piles of data he had before him. (In fact, he devoted an entire chapter to describing potential objections to his own arguments. That takes candor to a very high level. Yet creationists often just read that chapter in order to find objections to evolution, as if Darwin had not already thought the matter through, and as if modern science had not already resolved those objections, since Darwin so thoughtfully and disarmingly enumerated them.) Darwin's argument thus has more force than it would if he made claims that the data did not so clearly support. Darwin's great virtue as a scientist is that he did not let his own beliefs prejudice his investigations: he let the evidence speak plainly for itself. He was humble, painstaking and forthright.
Since I originally prepared this review, another superb edition of "On the Origin of Species" has been published by Harvard's Belknap Press, which provides excellent and substantial annotations to a facsimile of the original 1859 text, on the same pages as the text itself. That is a handsome volume which is immensely helpful because the annotations (prepared by James T. Costa, a biologist himself) explain so much. Darwin's writing is precise and clear but lay readers often have questions - or would, if we knew what to ask - that are answered in the annotations. Professor Costa updates much of what is being said in the text with current scientific knowledge, explains why Darwin is saying what he is saying, and generally offers valuable insights. The result is to make Darwin's book even more accessible to the general reader. Regrettably, that volume does not have all the rich contextual materials, illustrations and selections from other works that distinguish the edition under review here. Still, if your objective is to read Darwin's seminal work and comprehend it, Costa's is doubtless as good a book as there is. Thus, while it would be ideal if both of these books could be combined, we should be vastly grateful that two such outstanding editions of this important work became available at reasonable cost during the 200th anniversary of Darwin's birth and the 150th anniversary of "On the Origin of Species." You can take your pick, or if you really love Darwin and science, get both (as I did).
While I recommend reading "on the Origin of Species" in any edition, this is a lavish and eminently worthwhile volume, which I have added to the several editions I already own.
