In Nature a review of Dawkins' books and ideas"-http://www.nature.com/nature/journal/v529/n7587/full/529462a.html-"Books about science tend to fall into two categories: those that explain it to lay people in the hope of cultivating a wide readership, and those that try to persuade fellow scientists to support a new theory, usually with equations. Books that achieve both — changing science and reaching the public — are rare. Charles Darwin's On the Origin of Species (1859) was one. The Selfish Gene by Richard Dawkins is another. From the moment of its publication 40 years ago, it has been a sparkling best-seller and a scientific game-changer.-"The gene-centred view of evolution that Dawkins championed and crystallized is now central both to evolutionary theorizing and to lay commentaries on natural history such as wildlife documentaries. A bird or a bee risks its life and health to bring its offspring into the world not to help itself, and certainly not to help its species — the prevailing, lazy thinking of the 1960s, even among luminaries of evolution such as Julian Huxley and Konrad Lorenz — but (unconsciously) so that its genes go on. Genes that cause birds and bees to breed survive at the expense of other genes. No other explanation makes sense, although some insist that there are other ways to tell the story.-"What stood out was Dawkins's radical insistence that the digital information in a gene is effectively immortal and must be the primary unit of selection. No other unit shows such persistence — not chromosomes, not individuals, not groups and not species. These are ephemeral vehicles for genes, just as rowing boats are vehicles for the talents of rowers (his analogy).-"As an example of how the book changed science as well as explained it, a throwaway remark by Dawkins led to an entirely new theory in genomics. In the third chapter, he raised the then-new conundrum of excess DNA. It was dawning on molecular biologists that humans possessed 30-50 times more DNA than they needed for protein-coding genes; some species, such as lungfish, had even more. About the usefulness of this “apparently surplus DNA”, Dawkins wrote that “from the point of view of the selfish genes themselves there is no paradox. The true 'purpose' of DNA is to survive, no more and no less. The simplest way to explain the surplus DNA is to suppose that it is a parasite.”-***
"In the end, it was Michael Rodgers of Oxford University Press who enthusiastically published The Selfish Gene, after demanding “I must have that book!” when he saw early draft chapters. It was an immediate success, garnering more than 100 reviews, mostly positive. Dawkins went on to write books that were better in certain ways. The Extended Phenotype was more groundbreaking, The Blind Watchmaker more persuasive, Climbing Mount Improbable more logical, River out of Eden and Unweaving the Rainbow more lyrical, The Ancestor's Tale more encyclopaedic, The God Delusion more controversial. But they were all variations on the themes he so eloquently and adventurously set out in The Selfish Gene."-Comment: Most folks didn't recognize it as an analogy, and he went overboard in The God Delusion.
