From Publishers Weekly

Ryan (Virus X), a British physician, attempts to find a common explanation for much in our natural world. Ranging widely from the origin of life to the creation of human civilization and from the origin of sex to the root causes of many mental illnesses, Ryan turns to symbiosis ("an association between different species that persists for a long period") as the natural force responsible for all of this and much more. Additionally, he claims that Darwin and most modern-day "neo-Darwinists" ignore this basic premise of nature. Although there is some interesting information presented-particularly the possibility of diverse genomes interacting directly with one another through viral and bacterial intermediaries-the book's lack of biological and ecological sophistication greatly hampers its argument. Ryan's premise that "today all too many scientists assume that natural selection is the only mechanism of evolution," for example, is overstated. The concept of symbiosis is not nearly as novel as Ryan would have readers believe, and the modern view of evolution-and Darwin's original view as well-is a great deal more complex and interesting than Ryan portrays.

From Library Journal

It is a tribute to the genius of Darwinian theory that nearly 150 years after the publication of On the Origin of Species by Means of Natural Selection, it simultaneously survives in its essence and yet stimulates ongoing debate and new research. Physician Ryan (The Forgotten Plague; Virus X) focuses on a biological mechanism that Darwin and others, who stressed competition as the driving force of evolution, might have underestimated: symbiosis. Part 1 reviews the history of evolutionary theory, from the perspective of those who regard symbiosis as a vital agent for speciation. Even informed readers well versed in the literature will find new material in this discussion. Perhaps more daring, though, is Part 2, in which the author synthesizes a large volume of current thought, mixes it with his own ideas, and proposes novel theories about such unsettled issues as the origin of life on Earth and the critical roles of bacteria and viruses in evolution. Ryan covers a lot of territory-some of it considered suspect by many evolutionary biologists-but his assertions merit serious attention. For academic and larger public library science collections.

5.0 out of 5 stars Exploring the importance of symbiosis in evolution, April 17, 2003

By	Dennis Littrell (SoCal) - See all my reviews (TOP 50 REVIEWER)    (REAL NAME)    (COMMUNITY FORUM 04)

What Frank Ryan demonstrates in this book is that evolution by symbiosis has been a "blind spot" for evolutionists since the time of Darwin, and even today is greatly underestimated by the Darwinian establishment as a force in evolutionary change, especially in speciation.

Ryan, who is an expert on viruses having penned such well-received books as Virus X: Tracking the New Killer Plagues and The Forgotten Plague, begins with some interesting history from Darwin's time showing that Darwin did not (and could not, to be fair) appreciate the role symbiosis plays in evolution. Indeed Ryan demonstrates that the process of symbiosis, and its sister processes, parasitism, mutualism and disease, itself has been misunderstood. A relationship between species may begin as parasitism (or disease) and eventually evolve into a symbiosis. This experience between species has been going on since before there were multi-cellular organisms, and is a feature of every species in existence. All species interact with some other species in symbiosis.

This central realization of the book leads to something like a new way of looking at evolution. Natural selection is still a factor, but not necessarily the major factor anymore. This is implied in the discovery not too many years ago that the mitochondria that inhabit the cells in our body are almost certainly the remnants of a once free-living bacterium that, long ago in the primeval soup or near an undersea volcanic caldron, entered a cell and stayed. We are then the product of symbiosis, which may have begun as one cell invading the other, and over the eons turned into a domestic living arrangement with the invading cell providing power to the larger cell as that cell protects and feeds the symbiont that is now earning its keep.

How eye opening this conception is! Imagine the planet filled with life forms that are composed of a dozen, or perhaps hundreds of similar arrangements made over the eons. This is evolution not by gradual steps but evolution by saltation, with a new species arising almost (geologically speaking) immediately. Such a conception would explain many of the gaps in the fossil record.

Ryan builds a strong case. Along the way he looks favorably upon James Lovelock's Gaia hypothesis (one of my favorite modern ideas) and explores the role that viruses have had in gene transfers and speciation. He contrasts the neo-Darwinian reductionists (Dawkins, et al) with a different bred of evolutionary biologist including Lynn Margulis, Erik Larsson, Luis P. Villarreal, Kwang Jeon, John Maynard Smith, Eors Szathmary, and others. He also recalls some scientists who pioneered the ideas of symbiosis but never got the credit they deserved and were virtually ignored by the Darwinian establishment. It is surprising to see how "blind" the evolutionists were and how hard it was (and is) for new ideas to gain a foothold in any scientific community. But that is the way it should be: a new idea is just a notion until it finds collaborative support by being tested scientifically.

The Gaia metaphor is perhaps the ultimate expression of symbiosis in that it involves the entire biosphere. Ryan recalls Lovelock's view that our planet with its atmosphere and self-regulating processes represents "an emergent property" of life "tightly coupled with the physics and chemistry of the Earth's environment." (p. 112) This view has yet to gain full acceptance in the scientific community, but as knowledge of the symbiotic and cooperative nature of life (instead of an emphasis on the competitive nature) becomes more widely known (and as the old scientists retire!) I think that will change. Ryan makes it abundantly clear that (to recall an expression I either dreamed up or cribbed from somewhere) "Everything works toward a symbiosis."

One of the bugaboos in natural selection has been the idea of group selection. This has been debated for many decades, but it is becoming increasingly obvious (and Ryan strongly supports this view) that group selection is a reality. Ryan reports on the work of David Sloan Wilson and Elliott Sober, who used mathematic models to demonstrate how group selection might work. (p. 255) I have argued elsewhere for group selection so I won't go any further than to note that the biosphere that survives versus the one that doesn't (either through pollution, madness, lack of foresight, inability to ward off incoming disasters, etc.) is selected.

The most controversial idea in this book may be Ryan's insistence that natural selection should be seen as "an editorial force" acting upon what he calls "the creativity of the Genome." (p. 265). He has German biologist Werner Schwemmler suggest a balance by noting that the "combination of the two explanations (Darwinian gradualism and symbiotic saltation)" together progress "toward a unified theory of evolution." If this is correct, the way we view biological evolution is going to change dramatically in the years to come.

Ryan makes a distinction between endosymbiosis and exosymbiosis, the former involving one genome living within another, the latter pertaining to relationships such as that between pollinating insects and plants. I want to add that the exosymbiosis between humans and our crops and domestic animals has been the essential factor in our becoming a new sort of creature, one that evolves culturally rather than biologically, and will within a twinkling of time evolve into something that we cannot yet envision because of this rapid cultural evolution. Perhaps, as some have suggested, we will form a symbiosis with our intelligent machines and let Darwinian evolution edit the result.

Bottom line: an exciting book, challenging and filled with information and ideas.

5.0 out of 5 stars An update on new thought in evolutionary theory--excellent!, March 25, 2003

By	Grandma "Kathy" (Ocala, FL United States) - See all my reviews

I received a PhD at Cornell Univ. in 1971, in Ecology and Evolutionary Biology, with a minor in Population Genetics. For most of the succeeding 30 years, though, I have not worked in the field of biology. This book was like taking a new Master's Degree to update the last few decades. Ryan is clear, exhaustive in presenting new data and the development of a new paradigm; the book is well footnoted and thoughtful. His thesis that symbiosis is as important as mutation in the mechanisms of evolution, especially speciation and saltation (major jumps) is very well supported by the data he presents. Although the body of the book is focused on the biological data and its meaning, the author doesn't stop there. The argument also connects sociological, spiritual, environmental and political consequences of evolutionary theory--eugenics and Social Darwinism to Gaia, the world ecosystem, and the need to conserve the biological resources of the earth; and ends with an appeal for the need for awe before this mystery. Excellent and indispensable!

5.0 out of 5 stars A look at Symbiosis and, December 19, 2003

By	Stephen P. Smith "Author of Trinity: the scie... - See all my reviews (REAL NAME)

After the emergence of the first examples of prokaryote life, it had been thought that bacteria competed among themselves. That is, if we could intervene into the life of a bacterium and ask the little fellow: What is it that you are doing? What is this imperative that you hold? We would expect the answer that the bacterium holds challenge and necessity. And based on all outward signs it looks as if the bacterium must compete for its survival because of some egocentric imperative. Otherwise, the bacterium can just go on strike and there would be no surviving bacteria to direct such questions to, and we would not be here to ask such questions because our own survival depends upon the success of bacteria.

The bacterium is not an isolated unit onto itself. There is also everything else that makes up the biosphere and beyond. Is this imperative that the bacterium holds based on challenge and necessity of the individual cell? Or is it the empathetic wish of the biosphere to nurture the communities of prokaryote life and more? Is it the many, or the one? If it is our attention to avoid homomorphism, it must be that we cannot answer these questions. Therefore, the imperatives that life holds comes with two sides that are formally indistinguishable. Incidently, judging imperatives relates to the same confusion that Huw Price (see Time's Arrow and Archimedes' Point) described regarding the perceived passage on time - a very important observation. Does time unfold by the thermodynamic arrow as energies degrade into states of maximum entropy? Or is this just an issue of perspective as it is just as plausible for low energy states to unit into more ordered states?

Given that we hold these alternative views, it is not surprising that competing bacteria can fine tune their weapons to such an extent that they may win over their victims. They could be invited into their conquered host cells and become organelles like mitochondria and the cell nucleus. But the illusion of conquest is short lived. As the competing prokaryote cells find themselves to be one eukaryote cell, they discover a deeper symmetry and their felt imperatives flip as the competing bacterium find deep agreements in their mutual cooperation. Lynn Margulis will tell us this much, and Frank Ryan's book "Darwin's Blind Spot" presents a wonderful account of such symbiosis as discovered in biological evolution.

In writing on Albert Bernhard Frank's work on trees and fungi, Frank Ryan (on page 24 of "Darwin's Blind Spot") concludes:

"... The intimate cooperation between wholly different life forms - plants and fungi - is not only an amazing biological phenomenon but also a vitally important factor in the diversity of plant life on earth. It should have been of enormous interest to evolutionary theorists, but few scientists were paying attention. In those formative years at the end of the nineteenth century, as the fundamental principles of biology were being hammered into place in laboratories around the world, Darwinian evolution took center stage. And as Darwinism, with its emphasis on competitive struggle, thrived, symbiosis, its cooperative alter ego, languished in the shadows, derided or dismissed as a novelty."

How we perceive our self and our world will direct our imperatives. We may greet the broken symmetry with angry confusion and find ourselves competing (Publishers Weekly comes to mind). Or we may see the deeper symmetry and find ourselves cooperating. The imperatives are made of mind stuff as I note in my book, "Trinity". It is for this reason that I give Frank Ryan's book the highest recommendation.
