This is much, much better than James Watson’s 1968 The Double Helix, which is full of unbearable ego and sexist opinions. It even contains a chapter which explains the discovery of the double helix sans most of the commentary that made the earlier book annoying. Watson has definitely matured, thank goodness, and into a man I wouldn’t mind discussing genetics with. For example, he emphasises choice for pregnant women who know their babies have genetic disorders, insists that women have a right to decide on abortion which it is barbaric to deny, which I wouldn’t have predicted from his earlier book and which suggests a more liberal outlook than I expected.
In terms of the science alone, minus any comments on the writer, this is an excellent primer on DNA, covering most of what we currently understand about DNA. Being published nearly a decade ago now, it doesn’t comment on newer discoveries like the epigenetic control of gene expression, but it does cover just about everything in my college level online genetics class right now, with the added benefit of being something you can take at your own pace and without the horrible quantity of math that actually putting theories into practice requires (for example, he talks about finding a gene by reference to its association with a marker: I can calculate that if you give me half an hour, a calculator and a piece of paper — and allow me to cuss a good bit). It’s accessible to the layman, I think, but I still found it of interest despite my genetics classes and general interest in the field.
Some books leave me feeling that I’ve taken the wrong path in life. This is one of them. We know so many amazing, beautiful, astonishing things about DNA — and we have so much more to learn. This book made me long to have taken the other path in which I forced myself through the sciences for my A Levels, took a degree in genetics or something related, and became a geneticist. Watson clearly evokes the potential for this knowledge, and makes me wish I could add whatever intelligence I have to the process.
Skip The Double Helix, except as a historical document, but I do recommend DNA: The Secret of Life with little reserve.
