Evolution is a Fact and Dawkins Proves it!, September 23, 2009
Usually authors will start out their writing careers making a general case on behalf of something, and then later deal with the specific objections as they arise. But not Richard Dawkins. As the leading prolific evolutionary author in our generation he finally got around to writing the book that many authors would've written first, this one. Since up until now he has not set forth the evidence for evolution as a whole, he calls this book "my missing link" in his chain of books, and it's long overdue.
Taking the title from the Ringling Bros. and Barnum & Bailey Circus, Dawkins begins by asking us to imagine what it would be like to be a European history teacher who is "continually faced with belligerent demands to give equal time" in his classes to Holocaust deniers. To him that would be what it's like to teach the scientific fact of evolution around the world, especially in America, where 40% of us deny that humans evolved from other animals and who claim instead we were all created as distinct species not more than 10,000 years ago. Just like the Holocaust deniers these people are "history-deniers" too. The antidote to that kind of ignorant thinking is this present work, which presents "the positive evidence that evolution is a fact" (p.6). Many bishops and theologians embrace evolution as a fact, even if some of them accept it begrudgingly.
Who is he trying to reach? The creationist "history-deniers" themselves, but more importantly those who find themselves inadequately prepared to argue the case for evolution (p. 8).
He claims: "Evolution is a fact. Beyond reasonable doubt, beyond serious doubt, beyond sane, informed, intelligent doubt, beyond doubt evolution is a fact. The evidence for evolution is at least as strong as the evidence for the Holocaust, even allowing for eyewitnesses to the Holocaust. It is the plain truth that we are cousins of chimpanzees, somewhat more distant cousins of monkeys, more distant cousins still of aardvarks and manatees, yet more distant cousins of bananas and turnips...continue the list as long as desired...It didn't have to be true, but it is. We know this because a rising flood of evidence supports it. Evolution is a fact, and this book will demonstrate it. No reputable scientist disputes it, and no unbiased reader will close the book doubting it." (pp. 8-9).
These are very large claims he's making. Are they justified? Yes, I think so. I challenge the creationists to place this comprehensively argued book, which is illustrated by many diagrams and glossy full colored pictures, next to what a few ancient superstitious people wrote in the Bible and see which one makes the most sense. My bet is that if believers are truly interested in the facts they will see evolution is indeed a fact.
Dawkins knows how to communicate, he knows where to begin his case with dog breeding, and he knows science. It's practically all here within the pages of this book. The reason why we don't see evolutionary change is because it takes place slowly over generations, but dog breeders can do it quickly and efficiently. "Every breed of dog," Dawkins writes, "from dachshund to Dalmatian, from boxer to borzoi, from poodle to Pekinese, from Great Dane to Chihuahua, has been caved, chiseled, kneaded, moulded, not literally as flesh and bone but in its gene pool....The relevance to natural evolution is that, although the selecting agent is man and not nature, the process is otherwise the same." (p. 34).
With regard to flowers, birds and insects make these changes rather than humans, naturally, not artificially, just like the wind did before them: "Hummingbird eyes, hawk-moth eyes, butterfly eyes, hoverfly eyes, bee eyes are critically cast over wild flowers, generation after generation, shaping them, colouring them, swelling them, patterning and stippling them, in almost exactly the same way as human eyes later did with our garden varieties; and with dogs, cows, cabbages and corn." (p. 52). And he asks us: "If so much evolutionary change can be achieved in just a few centuries or even decades, just think what might be achieved in ten or a hundred million years?" (p. 37).
To believers who object that the earth isn't old enough Dawkins marshals overwhelming evidence that it is billions of years old, along with evidence piled upon still more evidence to show evolutionary development of life on earth is indeed the greatest show on earth, and he is clearly in awe of it.
There are a few great books on evolution but this is a superior book long overdue by today's leading communicator of science. You should get it and think through it, especially if you're a "history-denier." Face the evidence and then change your beliefs. It's the intellectually honest thing to do. Then you too will thank Dawkins like so many of us have for his writing in these areas.

A good book, but didn't live up to its subtitle, September 28, 2009
This book is the latest among a long list of evolutionary texts by Dawkins. By his own admission, this book differs from his previous works. While his other books assume the truth of evolution, and thus, sought to answer specific and common criticisms against evolution (often espoused by creationists), this is the first time Dawkins has attempted to lay out the actual evidence for its acceptance by the scientific community.
His book was well written, articulated in a readable style, and quite enjoyable. In fact, I found it difficult to put the book down. Dawkins provides a good general view of why scientists accept evolution and a good case for the plausbility of natural selection as the vehicle for adaptive change. However, I do have some criticisms of his book, which prevented me from giving it 5 stars, especially if I view it from the mindset of a biblical literalist (a view I once shared many decades ago... and these are the people who need the most convincing).
My number one complaint is that he did not provide much in evidence, and where he did provide evidence it was short on detail. For instance, in Chapter 2, Dawkins mentions that all dog breeds are descended from the wolf. Similarly, broccoli, cauliflower, kale, and other commonly distinct vegetables today are all descendants of the wild cabbage. While this might seem evident to the scientifically literate, if you don't accept evolution, you might need some convincing to show that this is true. But he doesn't provide evidence or even an explanation of how we know that dogs descended from wolves or broccoli from cabbage. He merely asserts this as evidence and then moves on to chapter 3, which concerns natural selction.
In chapter 3, he discusses flowers and insects (and birds) and presents this as evidence for evolution (specifically by natural selection). But he doesn't provide much explanation of how we know this to be true. For instance, why should we conclude that this arrangement between pollen producing flower and pollinating insect to be the result of co-evolution? How do we know that the pollen producing flower was not always the way it is and that the pollinating insect was not always the way it is and that these two merely "found" or discovered one another, in essence, falling into and exploiting a niche that was always present? [This might seem crazy, but this was actually used in an argument by a creationist]
Another criticism. He was careful to define the distinction between a scientific theory and a mere hypothesis or conjecture. Yet through much of the first few chapters of his book, he is short on evidence and long on speculation. For instance, he mentions the Heika japonica crab, with the resemblance of a samurai warrior on the back of its shell. While Carl Sagan states that this was the result of natural selection, Dawkins states it probably was not; it was likely coincidence. But this very case has often been cited as evidence for evolution (by selection). Is this evidence of evolution or not? And if not, then why is Dawkins' mentioning this in his book. If anything it calls into question how we determine that something is the result of evolution (and therefore qualified as evidence), as opposed to coincidence or something else? From this example, it seems almost arbitrary.
His review of the fossil record is compelling but rehashes the same information presented in other books. And he doesn't explain how we know that the discovered fossils represent a history of the same clad, as opposed to distinct, unrelated organisms. This is particularly important since we are often comparing fossils from different time periods, from different geographical locations, and don't have access to the entire skeletal remains (let alone genetic information) of the organisms that we are claiming are descended from one another. For example, how do we know that we aren't merely pattern seeking when we look at Pakicetus, Ambulocetus, and Basilosaurus? Or Australopithecus and Homo? Moreover, he spends most of the chapter on human evolution explaining why paleontologists feud over the specific genus (or species) of particular fossils and why such arguments would be predicted under evolution precisely because they represent intermediates. But his explanation could've been condensed into 1 paragraph. It would've been far better if he spent the time to present more evidence among the mountains of evidence that are claimed to exist.
His chapter, "You did it yourself in nine months", was spent explaining by analogy that matter is capable of self assembly from the bottom-up, rather than a top-down approach as espoused by creationists. He presents his hypothesis that this is possible via "local rules" and uses the analogies of the starling and origami as examples, but this is not evidence. In fact, while analogy can clarify and improve understanding, it does not constitute evidence. Dawkins forgets that the "local rules" are functioning from a template coded in our genome. Thus, can we truly say that it is the "local rules" that create the appearance of design when a recipe is necessary for determining these "local rules"? He needs to show that the genome is capable of self assembly by local rules and that a complex organism can be created from this base. While he implies that possibility during his discussion of viruses, he does not provide much detail. Thus, the reader is left unconvinced and with more questions. Thus, if you get to this point, you will have read 50% of the book and realize that much of the book has been devoted to explanation, speculation, hypotheses, and very few presentation of actual evidence. He uses computer models to illustrate or make his points. But once again, while these models may help explain concepts, they do not constitute evidence.
The last few chapters of the book are better (beginning around page 285), but by this time he's likely to have lost most of his readers, that is, those who have not already accepted evolution prior to reading this book.
My final criticism is in regard to his reference section. Most good books concerning scientific topics contain plenty of references to primary articles. But there are very few primary articles listed in this book. In fact, you'll find more scientific literature referenced in a pop diet book than here. And I am not joking! Go to a bookstore and look at the "Notes" section of Dawkins' book yourself. He does include a bibliography, but most of the entries represent secondary or tertiary sources. This doesn't mean the information is inaccurate, but it would've been nice to have citations to primary sources for those wanting to do further research.
There are some experiments mentioned in the book (rather clever ones too), but given the fact that evolutionists are always touting the volumes of evidence (and not just from fossils) for the fact of evolution, I was disappointed to find that only a handful are mentioned in the book. As mentioned earlier, most of the book is either providing background information (about rudimentary chemistry or biology), providing explanation, or tearing down common creationist arguments or criticisms against evolution, rather than focusing on positive evidence favoring evolution. Moreover, Dawkins practically ignores the evidence from molecular biology and glosses over genetics.
In short, Dawkins writes his book as if he is talking to a fellow evolutionist (preaching to the choir). But such a person does not need convincing or evidence of evolution. You can merely point or mention the "obvious" and expect the person to understand. You don't need to go into detail or explain much. On the other hand, if you do not accept evolution or require convincing, then you will likely find that Dawkins assumes too much and does not provide sufficient data or detail as to why evolution is the best explanation for the observations under discussion.
Needless to say, I was disappointed with the book since it failed to live up to its subtitle - "The Evidence for Evolution". A more apt title would've been "The Plausbility of Evolution". He makes a good case for the reasonableness of evolution but does not provide much compelling evidence. If you are a creationist contemplating whether there is sufficient evidence for evolution, you will not be convinced by reading this book. Two far superior books (that provide better and more compelling evidence) can be found in "Why Evolution is True" and "Making of the Fittest". It isn't that Dawkins' book is bad; it provides sufficient information (on a high level) to be useful and entertaining, but don't expect it to arm you for a debate with a creationist or use it as a reference. And don't expect your creationist friend to read it and walk away a convert.

Dawkins does it again, September 22, 2009
Evolution is an inescapable fact, and we should celebrate its astonishing power, simplicity and beauty, as Richard Dawkins notes in this marvelously titled book, the latest addition to his already impressive list of books on evolution.
Do we really need yet another "evidence for evolution" book? Well, yes we do. If only because of the alarmingly large number of educated people (especially in the United States) who hold virulent anti-evolution sentiments and prefer a supernatural, "intelligent design" explanation for the key questions in biology. But will the "history-deniers" read Dawkins? Leaving creationists and ID proponents aside, many people misunderstand evolution as a long chain of events that shape simple forms into more complex ones, rather than the branching and extinction of lineages. Therefore, open-minded readers should welcome yet another popular book on evolutionary biology, particularly if it has such a breadth and is so very well written as Dawkins'. As a teacher and communicator of science, Dawkins remains unsurpassed.
The "Greatest Show on Earth" is an ambitiously large survey of evolutionary biology; more than 400 pages (plus many color photos) one long argument for why evolution is a firmly-based scientific explanation, a fact. Even for those who accept the evidence for evolution, Dawkins' book is a stimulating and refreshing read; not least because of its conversational yet authorative tone (although Dawkins can't help but to lash out at religion here and there, it certainly is not an anti-religion book like "The God Delusion"). As one reviewer noted: if Charles Darwin would want to know how his theory had fared in the 21th century, this is the book he should read. My own first recommendation, however, would be Jerry Coyne's Why Evolution Is True. The latter book is equally well written and informative, but more concise and focused. What's more, Coyne is less polemical than Dawkins (BTW, Dawkins praises Coyne's book in his first chapter).
Dawkins covers the science in a rather standard fashion. The Galápagos islands, transitional fossils, embryology, artificial breeding, anatomy, etc., it's all there. Which is fine, of course. But those who are looking for a primer on the latest insights into evolutionary biology won't find it here. I would have liked to see more emphasis on the awesome power of molecular genetics in demonstrating evolution as an established fact. After all, the evidence in molecular biology is even more compelling than the fossil record (but, admittedly, more difficult to explain to lay persons). As an accompanying book, I would therefore recommend Sean Carroll's The Making of the Fittest: DNA and the Ultimate Forensic Record of Evolution, which focuses on how DNA directs the evolutionary process.
I'm puzzled why Dawkins chose not to mention the new insights into the molecular evolution of the eye. He discussed eye evolution at length in "The Blind Watchmaker" - as did Darwin in "The Origin of Species" - and it remains a favorite topic of the ID crowd. But astounding genetic findings have revolutionized the eye evolution field: the animal eye, from fruitfly to man, was "invented" only once during evolution. Darwin would have been thrilled! Dawkins could have scored a strong point here. A missed opportunity.
That being said, one can only hope that this book will convert at least some creationists and ID advocates; that the scales will fall from their religious eyes. But I have my doubts. To quote biologist Tom Tregenza: The fact that Darwin's theory makes so many predictions, none of which has ever been falsified, makes it easy to make a further prediction: it is only a matter of time before the ID proponents make it a fundamental tenet of their ideology that the pattern of life has been made that way specifically to fool biologists. In which case, evolutionists can take comfort in knowing that the creator specifically had THEM in mind at every step of the process.
