5.0 out of 5 stars
Wonderful intro to evo-devo, June 16, 2001
This review is from: From DNA to Diversity: Molecular Genetics and the Evolution of Animal Design (Paperback)
This is a short (about 200 pages)book, but it really is a fantastic introduction to evolutionary developmental biology. I've had an (amateurish) interest in this for awhile, and Carroll et al really clarify basic principles in the field. It is beautifully illustrated...full color diagrams and photos on almost every page. The basic concept is that there is a limited set of genes (the "toolkit") that control development and evolution throughout the animal kingdom. The basic function of these genes--like the hox genes, sonic hedgehog, ubx, and so forth--is clearly explained, and examples of the evolution of their function by changes in their own, and their target genes, cis-regulatory binding sites are shown. In depth coverage is given naturally to the fruit fly, but other insects also, and this is contrasted to the situation in vertebrate development. A real pleasure to read! Anybody with a college course or two in biology should find it comprehensible. I am absolutely positive this field is going to explode in the coming years, and I am certain that this book will be an inspiration for those who will become involved in it. If you're at all interested in the subject of the molecular mechanisms of evolution...don't hesitate to get this book!

Which Evo-Devo Book for You?, November 15, 2005
High School, College, Grad School? This book is at the grad school level. Carroll has also written Endless Forms Most Beautiful at the college level and The Making of the Fittest at the high school level. (You can check on "Read all my reviews" to read more about these.)
My own background is this: My formal education in biology consisted of an introductory course in college 40-odd years ago. Since then I've read a lot and in the last two years I've had a very strong interest in molecular and evolutionary biology. (For more info, click on my name, above. My Profile also has a link to my Listmania list of evolution books. Note that you don't have to be a grad student to read this book.)
I read From DNA to Diversity first and it was too much for me. I then read Endless Forms. That was pretty understandable, so I went back to Diversity and found it reasonable clear. I have since read it a third time and I am very fond of it.
Of the thousands of genes involved in the early development of animals, this book concentrates on a few, along with the proteins with which they interact and the various body parts they affect. Special attention is paid to the Hox genes and their insect homologues. Because these have large-scale effects in development, changes in them and in their regulation have profound effects on evolution. I especially enjoyed the section where Carroll combined many bits of information to show us the basic features that must have been present in the first bilaterally symmetric animal, that tiny but promising ancestor of us all. This is one of the bonuses we get for making the extra effort to read the grad-level book.
I find the text very clear and the overall organization - starting with the workings of the major toolkit genes, proceeding through descriptions of how those genes direct the overall shaping of the animal, and on to general considerations of evolution -- proceeds nicely.
[2 June 2007: This was one of the first reviews I wrote and I have added bits as my skills have improved. It got to be a bit patchy, so I have just finished a mafor revision.]

Tough going, but worth it!, August 4, 2001
This review is from: From DNA to Diversity: Molecular Genetics and the Evolution of Animal Design (Paperback)
As a professor of English at a Swedish university I devoted several years to studies of British history of ideas, leading up, eventually, to a book about the general public's reception of Darwin's evolution theory in Mid-Victorian Britain. The subject has fascinated me ever since. I have naturally followed with interest the subsequent debates on evolutionary biology, including its philosophical implications, in the pages of such journals as Science and Nature. Therefore the title of the present book appealed to me. It seemed to promise an introduction to aspects of the Darwinian theory which were certainly unknown to Darwin and his times. At the same time I realised that knowing more about genetics was a must for me, if I was to keep abreast of the debate about Darwin. I must confess I found it hard to assimilate the text, in spite of a clear style, and excellent illustrations. The sheer weight of unfamiliar facts and concepts made the reading laborious, to the point of exhaustion. But about half-way through the book (and helped by excursions into some undergraduate biological textbooks) I found that I had after all assimilated enough of the content to see that , for instance, the geneticist's seemingly perverse interest in the banana fly, Drosophila melanogaster, was indeed a rational choice. Many of the basic genes of the banana fly, especially those responsible for the early development of the fertilized egg onwards, are the same, or nearly so, as those that build up man. Not only are individual genes similar: their interactions with each other and their functions are also similar. For instance, though the banana fly's eyes are constructed entirely differently from those of man, their development, from egg to adult, are still controlled by genes that are clearly related to each other, and interact with other genes in similar ways. These fundamental similarities between an insect and a human implies that their common roots must lie some 500 million years back in time, presumably in tiny organisms existing in the oceans at that time. Moreover, it seems that the genes in question, to be found in the DNA of the chromosomes of both insects and humans, probably come from even tinier organisms, namely primitive bacteria, which the multicellular organisms had incorporated, at first as parasites or symbionts, in their own more advanced cells. If so, we are carried back even further back in time, perhaps to a billion years before now. We seem to be on the point of uniting the biological and physical (and chemical) evolution of our planet. Darwin surely would have loved that prospect, far beyond his own reach. This book is not an easy read. But it will yield a rich reward to the persistent reader. Incidentally, such a reader might do worse than go on to read an astronomer's view of the same wide panorama: Delsemme's 0ur Cosmic Origins.
