I think I must have been very tired when I read the first chapter of this all those moons ago, since last night I sat down and gobbled up 6 chapters in one sitting. If anything I found it LACKING in scientific detail. I mean, there’s popular science, then there are books that populise science’s findings without giving away any of its mechanisms.
I think this might fall into the latter category.
Obviously I’ve learned a few general facts, but I was hoping to learn more about the genome itself, how it actually does things, or failing that, things that are so mind bogglingly complex that we don’t have the slightest clue how it does them.
The closest Ridley has got to that so far is an awful lot of “length” comparisons – if the genome were a book, its pages could be piled from here to moon and back no less than 57 times, etc etc. Well yes, but OBVIOUSLY the genome contains a lot of information. It contains everything we are and could potentially be. That’s a lot of things. But it also contains a lot of redundent, repeat information so waxing on and on about its length seem, to me, rather to miss the point. I want to know about the non-redundent inforamtion, and I want to know what it does.
Maybe that will come in later chapters, but I’m not so sure. Each chapter seems to be a rather, dare I say it, shallow introduction to an “aspect” of genetics, without building into more depth anything mentioned in previous chapters. Most of the time it reads more like the history of the discovery of the genome than of the genome itself.
I get the feeling that this book is expressly written for people who have never even looked at a cell under a microscope before; who had never even heard the word “genome” before they saw this book. But maybe that’s simply the book showing its age (published before the publication of the human genome project); maybe it’s just a sign of how, even in the layman, basic understanding of genetics has surpassed all expectations less than 10 years after the books’s first appearance.
Ho hum. We shall see.
