The Selfish Gene by Richard Dawkins

'Dawkins's first book, was a smash hit... Best of all, he laid out this biology - some of it truly subtle - in stunningly lucid prose. It is, in my view, the best work of popular science ever written.'
H. Allen Orr, New York Review of Books

'A genuine cultural landmark of our time.'
 The Independent

US TV talk-show host Jay Leno, interviewing a passer-by:
Leno: How do you think Mount Rushmore was formed?
Passerby: Erosion?
Leno: Well, how do you think the rain knew to not only pick four presidents — but four of our greatest presidents? How did the rain know to put the beard on Lincoln and not on Jefferson?
Passerby: Oh, just luck, I guess.

Richard Dawkins is the doyen of the new evolutionary biologists, and puts his message across with masterly ease. The topic of evolution is not just one that causes controversies on the news, it is fundamentally important to us all, and when Dawkins wrote this book back in 1976, he was to have a huge impact on the general public. Dawkins writes very smoothly - this is not only a classic of popular science, it is one of the most beautiful examples.

Evolution, and its impact on genetics is indeed crucial to us all, but it has also been fundamentally important to biologists and zoologists. Before evolution they were very much second class scientists, more concerned with collating information and categorizing species than applying any scientific theory to explain what was observed. Because of this, biologists were said to suffer from "physics envy", because they felt inferior to the hard sciences. Evolution was to change all that - which is great, but the only irritating side effect that comes through a little in this book (and more so in the works of some other writers like Daniel Dennett) is the idea that evolution is not only a very important theory, but actually is MORE important than everything else. Dawkins opens the book by saying "If superior creatures from space ever visit earth [sic], the first question they will ask, in order to assess the level of our civilization, is 'Have they discovered evolution yet?'" This is just plain silly. But don't let it put you off the rest of the book, because it is superb.

The only part of the book that is open to significant question is the chapter or memes - Dawkins' idea of a conceptual equivalent of genes that allow anything from ideas to advertising jingles spread through society. It was a nice thought, but has been too often taken as scientific fact in popular science writing, where it is anything but a proven concept. But that's a minor part of the book.

Anyone who has any doubts that "evolution is just a theory" needs to read this. And I stress to read it. All too often, people have just come across the title, or heard it being talked about and assumed that Dawkins is literally suggesting that genes have conscious will, and act in order to make things better for themselves. In fact, Dawkins is master of metaphor, and that's all it was ever intended to be. As he points out, there is no suggestion that we are puppets to our genes, and have to act in a manner that furthers the benefit of our genes. Many of us choose to act differently. But there is equally no doubt of the power of genetic evolutionary pressure. Also, a lot of the problem is that most people have a very poor grasp of probability and statistics, and find it difficult to see evolution, and its impact on genetic action in these terms. Some will always struggle against the concepts here, but everyone should have this book on their reading list.

The Selfish Gene is now in a third edition, also known as the 30th anniversary edition, which has extra prefaces in the front, but unless you are particularly interested in the development of the attitude to evolution and genetics, our advice is to skip these and get onto the main text.

Yes, genes can be selfish - To mark the 30th anniversary of Richard Dawkins’s book, OUP is to issue a collection of essays about his work. Here, professor of psychology at Harvard University, wonders if Dawkins’s big idea has not gone far enough…click here to read what Prof. Steven Pinker has to say on the matter and the man.

Eating the Sun: How Plants Power the Planet by Oliver Morton

'A fascinating and important book.'
 Ian McEwan

'Everything you could possibly want from a popular science book. There is wonder here, and intellectual excitement; clear explanation and lyrical writing; and much new insight into how the world works, linking the very small and very large.'
 Jon Turney, Independent

'When you are done with this book you will see the world differently and understand it better. Going directly to the most important question of our time - the origin of the carbon/climate crisis - and delving deeply into it, ‘Eating the Sun’ transcends science writing as we usually think of it.'
 Kim Stanley Robinson

'Eating the Sun' is the story of the discovery of a miracle: the source of life itself.

From the intricacies of its molecular processes to the beauty of the nature that it supports, 'Eating the Sun' is a wondering tribute to the extraordinary process that has allowed plants to power the earth for billions of years.

Photosynthesis is the most mundane of miracles. It surrounds us in our gardens and parks and countryside; even our cityscapes are shot through with trees. It makes nature green -- the signature of the pigments with which plants harvest the sun; wherever nature offers us greenery, the molecular machinery of photosynthesis is making oxygen, energy and organic matter from the raw material of sunlight, water and carbon dioxide.

We rarely give the green machinery that brings about this transformation much thought, and few of us understand its beautifully honed mechanisms. But we are dimly aware that those photosynthetic mechanisms are the basis of our lives twice over: the ultimate source of all our food and the ultimate source of every breath we take.

'Eating the Sun' will foster and enrich that awareness. And by connecting aspects of photosynthesis that are vital to our lives, to the crucial role its molecular mechanisms have played through more than two billion years of the earth's history, 'Eating the Sun' will change the way the reader sees the world.

In Defense of Self: How the Immune System Really Works by William Clark

Our immune system is the only thing standing between us and a sea of microbial predators that could send us to an early and ugly death.

Equipped with genetic, chemical and cellular weapons, it evicts unwelcome microrganisms that find the human body a delightful place to live, carefully admitting only the few microbes that our bodies need to help us digest food and process vitamins.

When the system works successfully, the vast majority of disease-causing microbes - bacteria, viruses, molds and a few parasites - are kept at bay. But the immune system isn't perfect. The same system that could save us in the event of a bioterrorist attack, prevents us from accepting potentially life-saving organ transplants. It overreacts at times, turning too much force against foreign invaders, causing serious - occasionally lethal - collateral damage to our tissues and organs.

Worse yet, our immune systems may decide we ourselves are foreign and begin snipping away at otherwise healthy tissues, resulting in autoimmune disease. And the system itself is the target of one of the most deadly viruses humans have ever known: HIV, the agent of AIDS.

In In Defense of Self, William Clark invites you on a whirlwind tour of your immune system. Along the way, he introduces some of most important medical advances and challenges of the past hundred years, from the development of vaccines and the treatment of allergies, autoimmunity and cancer, to prolonging organ transplants and combating AIDS.

William Clark not only explains how a vital part of our bodies works to "serve and protect," he also provides background for the exciting research themes of today that will produce the medical breakthroughs of tomorrow.

The Greatest Show on Earth: The Evidence for Evolution by Richard Dawkins

'This is the book Richard Dawkins needed to write and many need to read ... clear, absorbing and vivid.' Bishop Richard Harries

'Dawkins combines an artist's wonder at the virtuosity of nature with a scientist's understanding of how it comes to be.'
 Matt Ridley

'Whether it’s Lenski’s bacteria or our own ancestors, Richard Dawkins discusses the evidence for evolution with his usual charm, style, clarity and brilliance.' Simon Singh

Charles Darwin’s masterpiece, On the Origin of Species, shook society to its core on publication in 1859. Darwin was only too aware of the storm his theory of evolution would provoke but he would surely have raised an incredulous eyebrow at the controversy still raging a century and a half later.

Evolution is accepted as scientific fact by all reputable scientists and indeed theologians, yet millions of people continue to question its veracity.


In The Greatest Show on Earth Richard Dawkins takes on creationists, including followers of ‘Intelligent Design’ and all those who question the fact of evolution through natural selection. Like a detective arriving on the scene of a crime, he sifts through fascinating layers of scientific facts and disciplines to build a cast-iron case: from the living examples of natural selection in birds and insects; the ‘time clocks’ of trees and radioactive dating that calibrate a timescale for evolution; the fossil record and the traces of our earliest ancestors; to confirmation from molecular biology and genetics.

All of this, and much more, bears witness to the truth of evolution.

The Greatest Show on Earth comes at a critical time: systematic opposition to the fact of evolution is now flourishing as never before, especially in America. In Britain and elsewhere in the world, teachers witness insidious attempts to undermine the status of science in their classrooms. Richard Dawkins provides unequivocal evidence that boldly and comprehensively rebuts such nonsense. At the same time he shares with us his palpable love of the natural world and the essential role that science plays in its interpretation. Written with elegance, wit and passion, it is hard-hitting, absorbing and totally convincing.

Extract from Chapter One

Imagine that you are a teacher of Roman history and the Latin language, anxious to impart your enthusiasm for the ancient world — for the elegiacs of Ovid and the odes of Horace, the sinewy economy of Latin grammar as exhibited in the oratory of Cicero, the strategic niceties of the Punic Wars, the generalship of Julius Caesar and the voluptuous excesses of the later emperors. That’s a big undertaking and it takes time, concentration, dedication. Yet you find your precious time continually preyed upon, and your class’s attention distracted, by a baying pack of ignoramuses (as a Latin scholar you would know better than to say ignorami) who, with strong political and especially financial support, scurry about tirelessly attempting to persuade your unfortunate pupils that the Romans never existed. There never was a Roman Empire. The entire world came into existence only just beyond living memory. Spanish, Italian, French, Portuguese, Catalan, Occitan, Romansh: all these languages and their constituent dialects sprang spontaneously and separately into being, and owe nothing to any predecessor such as Latin.

Instead of devoting your full attention to the noble vocation of classical scholar and teacher, you are forced to divert your time and energy to a rearguard defence of the proposition that the Romans existed at all: a defence against an exhibition of ignorant prejudice that would make you weep if you weren’t too busy fighting it...

...The plight of many science teachers today is not less dire. When they attempt to expound the central and guiding principle of biology; when they honestly place the living world in its historical context — which means evolution; when they explore and explain the very nature of life itself, they are harried and stymied, hassled and bullied, even threatened with loss of their jobs. At the very least their time is wasted at every turn. They are likely to receive menacing letters from parents and have to endure the sarcastic smirks and close-folded arms of brainwashed children. They are supplied with state-approved textbooks that have had the word “evolution” systematically expunged, or bowdlerized into “change over time”. Once, we were tempted to laugh this kind of thing off as a peculiarly American phenomenon. Teachers in Britain and Europe now face the same problems, partly because of American influence, but more significantly because of the growing Islamic presence in the classroom — abetted by the official commitment to “multiculturalism” and the terror of being thought racist.
