Eye-opening at the tiniest scale

The Selfish Gene

By Richard Dawkins

Sometimes it’s just good fun to read a book by a writer with such a distinctive and strident voice that it appears to drown out all opponents. As a scientist, Dawkins is probably sensible enough to listen to others in his field. But the great joy of this book is the singular vision he offers. Dawkins pushes through the crowd of a generation of scientists in order to clamber up to the soapbox and scream his thrilling theory. His view of the gene as a competitive, political molecule worthy of Ancient Rome is enticingly reflected in his own audacious approach. While Darwin dithered, Dawkins dives in.

And then there is the theory itself. Pick your superlative: influential, controversial, profound. History has shown that it is all these things and more. To the layman, the concept behind The Selfish Gene is exciting. To the scientist, it must have been downright shocking. Dawkins’ central thesis rests on the very plausible assumption that until his book, science has viewed genes upside down. He argues that because we have studied bodies for centuries, upon the discovery of genes, we formulated theories about how genes code for different aspects of our biology and why. The selfish gene theory posits that bodies are merely survival machines produced by the genes themselves in order for them to continue replicating. It’s a huge idea of the kind that does not come around very often.

And Dawkins is the writer to do it justice. His prose is clear, crisp and not technical in the slightest. He uses brilliant examples that open the reader’s eyes to the natural world. Above all else, his rhetoric is deeply attractive.

Genome

By Matt Ridley

The genome is a treasure trove. Full of both mystery and truth, it has to be one of the most fascinating artefacts of nature. The complexity of the genome makes it a difficult subject to tackle, but Ridley is brave and smart enough to give it a shot. In this book, he hits the nail on the head.

Genome is already over a decade old, and you can hear Ridley’s acceptance that very soon after his book is to be published, the science will have moved on. And that is indeed the case: gone is the excitement around Dolly the sheep and the hysterical response to CJD. These are but two examples of how times have changed, but Ridley’s book is still deeply useful. It is a historical account of the all the major discoveries to do with the genome and, what makes this book very special, the alarming interplay between genes, culture and behaviour.

You would be forgiven for picking up this popular science book and expecting just genetics. But Ridley’s far too brilliant for that – he acknowledges that people are more interested in the influence of genes on our behaviour, and vice versa. That’s the real story of the genome. So every chapter here reveals yet another secret of the genome’s science, but also its impact on our cultural development. Ridley leaves no stone unturned as he pulls together science with psychology, evolution and sociology.

Ridley takes his reader on an extraordinary journey into the very heart of what it means to be human – that is no overstatement.
