A WIDE-RANGING COLLECTION OF DAWKINS’ ESSAYS ON MANY SUBJECTS
Clinton Richard Dawkins (born 1941) is an English ethologist and evolutionary biologist, as well as an emeritus fellow of New College, Oxford. He has written some of the most creative and challenging defenses of evolutionary theory.
He wrote in the “Author’s Note” of this 2003 book, “This book constitutes a personal selection … by the Editor… from among all the articles and lectures, reflections and polemic, book reviews and forewords, tributes and eulogies that I have published (or in a few cases not previously published) over 25 years… I like to think that the greater part of it is good-humored, perhaps even humorous. Where there is passion, well, there is much to be passionate about. Where there is sadness, I hope it … still looks to the future… My contribution to the book itself has been to write the preambles to each of the seven sections, reflecting on the essays … and the connections between them.”
The title of the book comes from a phrase Darwin wrote in an 1856 letter to his friend Joseph Dalton Hooker: ‘What a book a Devil’s Chaplain might write on the clumsy, wasteful, blundering low and horridly cruel works of nature.’ Dawkins comments, “A process of trial and error, completely unplanned and on the massive scale of natural selection, can be expected to be clumsy, wasteful and blundering… Clumsy and blundering though the PROCESS undoubted it, its results are opposite. There is nothing clumsy about a swallow, nothing blundering about a shark.” (Pg. 10)
He acknowledges, “Science has no methods for deciding what is ethical. That is a matter for individuals and for society. But science can clarify the questions being asked, and can clear up obfuscating misunderstandings… Science cannot tell you whether abortion is wrong, but it can … warn you that you may be acting inconsistent if you think abortion is murder but killing chimpanzees is not… Science cannot tell you whether it is wrong to clone a whole human being. But it can tell you that a Dolly-style clone is just an identical twin…” (Pg. 39)
He points out, “we are privileged to know that exact letter-to-letter sequence of massive DNA texts. It is claimed that more than 98 per cent of the human genome, when measured in this way, is identical with chimpanzees’… Nevertheless, we must beware of being carried away the by euphoria of it all. That 98 percent doesn’t mean that we are 98 percent chimpanzees. And it really matters which unit you choose to make your comparison. If you count the number of whole genes that are identical, the figure for humans and chimpanzees would be close to zero… The point is that we should use such percentages not for their absolute value but in comparisons between animals.” (Pg. 84)
He observes, “Another twentieth-century idea which is probably important in human evolution … is neoteny: evolutionary infantilization… Such neoteny has been suggested as a way in which a lineage can suddenly initiate an entirely new direction of evolution, at a stroke… Juvenile chimpanzees resemble humans far more than adult chimpanzees do. Human evolution can be seen as infantilism.” (Pg. 87)
He suggests, “We can now assert with confidence that the theory that the Earth moves round the Sun … will be right in all future times… We cannot quite say that Darwinism is in the same unassailable class. Respectable opposition can still be mounted, and it can be seriously argued that the current high standing of Darwinism in educated minds may not last through all future generations… new facts may come to light which will force our successors of the twenty-first century to abandon Darwinism or modify it beyond recognition… ‘Core Darwinism,’ I shall suggest, is the minimal theory that evolution is guided in adaptively nonrandom directions by the nonrandom survival of small random hereditary changes.” (Pg. 94-95)
He states, “this argument points up an irony in the claim, frequently made by lay opponents of evolution, that the theory of evolution violates the Second Law of thermodynamics, the law of increasing entropy or chaos within any closed system. The truth is opposite… The common error… is to personify the Second Law: to invest the universe with an inner urge or drive towards chaos… It is partly this error that has led people to accept the foolish notion that evolution is a mysterious exception to the law… if a system wanders anywhere in the space of all possible arrangements, it is almost certain… that we shall perceive the change as an increase in disorder…” (Pg. 98-99)
He explains, "In September 1997, I allowed an Australian film crew into my house … without realizing that their purpose was creationist propaganda… they issued a truculent challenge to me to ‘give an example of a genetic mutation or an evolutionary process which can be seen to increase the information in the genome.’ … it was at this point I tumbled to the fact that I had been duped into granting an interview to creationists---a thing I normally don’t do, for good reasons. In my anger I refused to discuss the question further, and told them to stop the camera. However, I eventually withdrew my peremptory termination of the interview, because they pleaded with me that they had come all the way from Australia specifically to interview me... I therefore relented… When I eventually saw the film [‘A Frog Into a Prince’] … I found that it had been edited to give the false impression that I was INCAPABLE of answering the question about information content… Pathetic as it sounds, their entire journey from Australia seems to have been a quest to film an evolutionist failing to answer it… I shall try to redress the matter now in constructive fashion by answering the original question…” (Pg. 107-108)
He observes, “The answer in practice is … all bound up with a vigorous debate over whether evolution is, in general, progressive. I am one of those associated with a limited form of yes answer… I don’t think that anybody would deny that … there has been a broad overall trend towards increased information content during the course of human evolution from our remote bacterial ancestors. People might disagree, however… whether such a trend is to be found in all, or a majority of evolutionary lineages…” (Pg. 119)
He notes, “Already, DNA taxonomy has turned up some sharp surprises. My traditional zoologist’s mind protests almost unendurably at being asked to believe that hippos are more closely related to whales than they are to pigs. This is still controversial. It will be settled, one way or the other, along with countless other such disputes, by 2050. Actually, it will not be necessary to sequence entire genomes to dissolve taxonomic uncertainty forever.” (Pg. 133)
Some of the most interesting parts of the book are his musings about Stephen Jay Gould: “We were cordial enough when we met, but it would be disingenuous to suggest that we were close. Our academic differences have even been spun out to book length… Yet, despite our differences, it is not just the respect due to the dead that leads me to include in this book a section on Stephen Gould with a largely positive tone… Enemies is too strong a word for a purely academic dispute, but admiration is not, and we were shoulder to shoulder on so much. In his review of my ‘Climbing Mount Improbable,’ Steve invoked a collegiality between us, which I reciprocated, in the face of a shared enemy.” (Pg. 219)
He continues, Stephen Gould was my exact contemporary but I always thought of him as senior, probably because his prodigious learning seemed to belong to a more cultivated era… For good or ill, Steve Gould had a huge influence on American scientific culture, and on balance the good came out on top… Although we disagreed about much, we shared much too, including a spellbound delight in the wonders of the natural world, and a passionate conviction that such wonders deserve nothing less than a purely naturalistic explanation.” (Pg. 220-221)
He goes on, “what did we disagree about?... Gould saw natural selection as operating on many levels in the hierarchy of life. Indeed it may, after a fashion, but I believe that such selection can have evolutionary consequences only when the entities selected consist of ‘replicators.’ … Genes are such entities… Gould… saw genes only as ‘book-keepers,’ passively tracking the changes going on at other levels. In my view… If a genetic change has not causal influence on bodies, or at least on SOMETHING that natural selection can ‘see,’ natural selection cannot favor or disfavor it. No evolutionary change will result.” (Pg. 260)
This book will be “must reading” for anyone interested in Dawkins’ other books, or contemporary evolutionary theory in general.
