5.0 out of 5 stars
Challenging and fascinating, October 2, 2011
This review is from: The Logic of Chance: The Nature and Origin of Biological Evolution (FT Press Science) (Hardcover)
In the preface to this book, the author writes that he set out with the desire to write a popular book along the lines of A Brief History of Time but on the subject of evolution. He soon recognized that the book "refused to be written that way" and became much more scientific and specialized. This is quite true. I am not a biologist but a physician, so I have had a fair number of biology courses, but much of this book was at about the limit of my ability to absorb, or even beyond. You probably won't get very far without a basic understanding of molecular biology: chromosomes, genes, DNA, tRNA, mRNA, transcription, translation, replication, ribosomes, operons, introns, splicing, and so on. On the other hand, if you have that background and some basic understanding with the concepts of biological evolution, you'll probably do fine with the book; little else is required--no math or biochemistry, for example. So be sure to take advantage of the "Look Inside" feature before you buy. It's important to note the subtitle, "The Nature and Origin of Biological Evolution." This is not a chronicle of evolution, but a rather detailed (for a layperson) look at mechanisms of evolution, mostly at the genetic level, along with some reasoning and speculation about how the whole ball of wax got started. You should also be aware that the "highest" organisms considered in any detail are the earliest, single-cell eukaryotes. Animals are, after all, only "a single, relatively small, tight group of eukaryotes" while bacteria and viruses are the most numerous and successful organisms on earth. Virtually the entire book is based on the evolution of bacteria, archaea, and viruses, though occasionally animals and plants are mentioned in passing. This is fine, since the purpose of the book is to explore evolution beyond the classical understanding of natural-selection-based, adaptive evolution, and also to probe the earliest origins of life. I'm not sure what previous reviewer Jim means by "But it will be a classic because it deals handily with nearly every contested area of evolution, neatly demolishing every criticism leveled by creationists. It does this by making positive statements about what is known rather than by arguing against creationism." The book certainly deals with some contested areas, but the contests are among evolutionary biologists and not between creationists and biologists. This book and creationists are not in the same universe of discourse. A few of the book's interesting points include: * At least at the "interesting" scale of evolution (up to the origin of eukaryotes), adaptation or positive natural selection is not the major factor in genetic change: "the overall quantifiable characteristics of genome architecture, functioning and evolution are primarily determined by non-adaptive, stochastic processes. Adaptations only modulate these processes." * Increasing complexity over time is not a measure of some kind of "progress" of evolution, but is due largely to two factors: (1) a random-walk phenomenon in which more complex structures will occur by chance given longer periods of time (2) the natural result when the effective population size is not great enough for purifying selection to eliminate slightly deleterious mutations. "Junk" DNA can accumulate as a result, both requiring and providing the substrate for complexity. Complexity as a "syndrome" of less-numerically-successful lineages coping with junk. * Viruses as a separate "empire" of life not as a derivative of cellular life. The important role of viruses (and other conceptually-related entities) in evolution especially through horizontal gene transfer. * The importance of the "Red Queen" arms-race between hosts and parasites (including especially viruses and other selfish elements) in driving genetic change. * The logical necessity of an "RNA world" as precursor of cellular life. At the same time, the extreme improbability of the whole replication system arising in this universe: a "back of envelope" estimate of the probability of life evolving somewhere in the observable universe in 10 billion years is something like one in 10 to the power 1000. The author resorts to the "many worlds in one" hypothesis in which there are an infinity of infinite universes, so every possible event happens in not only one but an infinite number of them. We're here to observe one of these extremely improbable universes only because, of all these universes, living observers can only exist in the ones where life did arise ("weak anthropic principle").

Tremendous analysis of mathematical basis of chance for advanced student - not for beginners in evolutionary science, September 16, 2011
This review is from: The Logic of Chance: The Nature and Origin of Biological Evolution (FT Press Science) (Hardcover)
Customer review from the Amazon Vine™ Program (What's this?)
Evolution is obviously a popular topic today, and the science is moving so fast that a book older than 10 years likely contains outdated information. One topic of recent interest has been mathematical difficulties in the probabilities and direction of evolution as clasically understood. In my own mind, I often liken Darwin to Lord Kelvin. Lord Kelvin was correct that the world was far older than 6000 years, but his estimate of 20-400 million years based on estimates of the cooling of the Earth seems laughable by our standards today. Even during his own day geologists could marvel as the scientific rigor of his calculations, but still say that something seemed wrong with a world of a mere 400 millions years. Kelvin used good science, but not all of the science, missing the role radioactivity played in the cooling of the Earth.
Darwin is like Kelvin, in that he got the rough idea, but the details would take further scientific understanding. Kelvin was saved by the advanceds in astronomy and chemistry, but deeper insight into Darwin's ideas would take much more research.
In his comprehensive new book, "The Logic of Chance", Eugene Koonin starts with an excellent overview of the history of evolutionary theory. For instance, Darwin did not known about genetics and he did not know about viruses and bacteria or eukaryotes. When he thought of irreducible complexity, he thought of the eye, not the multi-protein clotting process or the bacterial flagella. Darwin could only observe gross physical features, and the subtleties of the engine of evolution were invisible to him. Koonin also notes that Darwin wasn't even the first to observe the change of species over time. Writings from Greek and Indian sources present what we might now call evolution, and Darwin was also preceded by Lamarck, Lyell, and others.
Koonin establishes that what made Darwin unique was that he brought together many of these ideas into one framework (entirely rationalist, survival of the fittest, and speciation) and created the most compelling presentation ever seen.
One problem plaguing evolutionary science compared to cosmology (something more accepted) is the difficulty of experimentation. Whereas cosmologists have their theories supported by physicists performing experiments, biologists have more difficulty replicating or observing speciation. Indeed, Koonin's primary contention, which could be well misunderstood, is that we really have not understood much of the engine of evolution until recently. Koonin's book presents several diversions from the classical notion of the "Tree of Life", where we think of linear progression, one ancestor begetting 2 different lineages, etc. True evolution is far more complex that the "ascent of man" image or progression of horses. As creationists would object, these are stories that fit our fossil record, but not science.
Koonin brings mathematics and analysis to the process of evolution, showing how random chance combines with survival of the fittest, and demolishes the classical notion of evolution as striving towards greater complexity or improvement. Indeed, he shows through numerous examples how the complexity of evolution makes modeling immensely difficult. One particular noteworthy image is the 3-d surface plot of a "fitness landscape" showing how certain maxima can increase fitness, but random chance can move from one peak to another. There is no tree of life, no strive towards complexity. There is a random forest with localized maxima of fitness where species will land, with no direction in particular.
I recommend this book as you advance in your study of evolution and crave a mathematical understanding of just how the evolutionary process can function.
I do not recommend this book if you are just starting to learn about Evolution. The first chapter is a great overview, but the reader will jump the track after that. I read books on cosmology all the time, and yet my background in physics and math was not quite enough to make the biology easy to follow. I struggled through it and you likely will as well. If you a religious person looking to understand evolution and creationism, I recommend "Finding Darwin's God" by Kenneth Miller or "The Challenge of Creation" by Rabbi Slifkin. For a modern overview of evolutionary science without the religion (or religion bashing), I recommend "Evolution is True" by Jerry Coyne and "Written in Stone" by Brian Switek.
5 stars for a tremendous addition to the library of evolutionary science, and a necessary one for the mathematical mind struggling to understand the nature of chance and how it relates to evolutionary science.

4.0 out of 5 stars
Heavy but very thought provoking read, September 19, 2011
This book is targeted at the experts but can be understood well enough by knowledgeable amateurs with some background in genomics (even unofficial; mine comes from my hobby of reading research papers because I am fascinated with biology). Having already read a good number of Dr. Koonin's papers as well as several others referenced in the book helped.
Anyway, this was a fascinating, thought-provoking read, though it was also rather difficult. Koonin's writing style, which serves him quite well in academic papers, doesn't translate extremely well to a full length book. For the sake of comparison, because both books seem to be targeted at a similar level crowd, it is not as readable as "The Extended Phenotype" by Richard Dawkins.
However, the ideas are fascinating, and this book seems to be an excellent overview of modern genomics research and what it tells us about what we understand and misunderstand about evolution. I certainly learned a lot about these topics as well as directions that future research will be taking. While I was less than impressed with some of the conclusions near the end (for example, the appeal to MWO and weak Anthropic Principal seemed to me to be a cop-out and at best should be a hypothesis of last resort).
However, I am not an expert, just an interested knowledgeable amateur, so I am not in the best position to judge Dr. Koonin's interpretations of the various data and research. But, whether his interpretations are spot on or not, they are certainly quite thought provoking, and will certainly serve science by creating discussion and lying groundwork for real testable hypotheses of all of the topics of genomics and evolution he discussed.
If you are very interested in biology, genetics, genomics, and evolution, you will want to read this book.
