Phase transitions occur throughout nature. The most familiar example is the one that occurs in water – the abrupt, discontinuous transition from a liquid to a gas or a solid, induced by a subtle environmental change. Practically magical, the ever-so-slight shift of temperature or pressure can induce an astonishing transition from one entity to another entity that bears little resemblance to the first. So "convenient" a feature is seen throughout the domains of physics and chemistry, and one is therefore led to wonder whether it might also be common to biology. Indeed, many of the most fundamental cellular processes are arguably attributable to radical structural shifts triggered by subtle changes that cross a critical threshold. These processes include transport, motion, signaling, division, and other fundamental aspects of cellular function. Largely on the basis of this radical concept, a symposium was organized in Poitiers, France, to bring together people who have additional evidence for the role of phase transitions in biology, and this book is a compendium of some of the more far-reaching of those presentations, as well as several others that seemed to the editors to be compelling. The book should be suitable for anyone interested in the nature of biological function, particularly those who tire of lumbering along well trodden pathways of pursuit, and are eager to hear something fresh. The book is replete with fresh interpretations of familiar phenomena, and should serve as an excellent gateway to deeper understanding.

During evolution, there have been several major changes in the way that genetic information is organized and transmitted from one generation to the next. These transitions include the origin of life itself, the first eukaryotic cells, reproduction by sexual means, the appearance of multicellular plants and animals, the emergence of cooperation and of animal societies, and the unique language ability of humans. This is the first book to discuss all of these major transitions. In discussing such a wide range of topics in one volume, the authors are able to highlight the similarities between different transitions - for example, between the union of replicating molecules to form chromosomes and of cells to form multicellular organisms. The authors also show how an understanding of one transition sheds light on others. A common theme in the book is that entities that could replicate independently before the transition can replicate afterwards only as part of a larger whole. Why, then, does selection between entities at the lower level not disrupt selection at the higher level? In answering this question, the authors offer an explanation for the evolution of cooperation at all levels of complexity. Written in a clear style, and illustrated with many original diagrams, this book can be read with enjoyment by anyone with an undergraduate training in the biological sciences. It will be ideal for advanced discussion groups on evolution. Although the content ranges widely from molecular biology to linguistics and from intragenomic conflict to insect societies, no detailed knowledge of any of these topics is required. Mathematical models are clearly explained, and equations and formulae are kept to a minimum.

Arthur Milnes Marshall was a 19th-century scientist who gave lectures addressing the biological debates of his time. They covered topics including evolution, embryology, development and inheritance, with Charles Darwin’s name and those of other important biologists distributed liberally throughout. Marshall was a zoologist, embryologist, anatomist and Darwin enthusiast, as well as an accomplished mountaineer and sportsman. He was a humanist, an admired academic teacher and brilliant public educator. The lectures reveal his passion for communicating his subject, to his students and to the working men and women of Manchester, and they provide a remarkable snapshot of the state of biological science at the close of the 19th century. His death in 1893 aged only 41, on a climbing expedition in the Lake District, left a fascinating time capsule in the form of lectures from a critical transitional period in the history of biology. Evolution by natural selection was the established doctrine but genes were undefined, with Mendel’s work yet to be recognised. Embryology was suggesting recapitulation but ancestry, genetics and missing links awaited liberation from theoreticians and the stones of palaeontology. Microscopy was flourishing and cell science was finding its feet, but DNA and molecular science were far in the future. Had Marshall lived and worked into the 20th century, these lectures would undoubtedly have been superseded and forgotten. Instead, they reveal biology’s transformation from a descriptive exercise to an experimental science, its rejection of purpose and design in evolution, and the shift of its axis from continental Europe to Britain and the United States. Professor Martin Luck discovered these lectures (published by CF Marshall in two volumes shortly after his brother’s death) languishing in a university corridor. His careful curation, introductions to each lecture and copious annotations on the organisms, theories and scientists discussed, illuminate their significance as prequels to modern biology. Marshall’s own story brings the lectures and their social context into sharp relief. Biology in Transition will interest anyone curious about the history of science, especially biology, evolution, genetics and its 19th-century pioneers.

Drawing on recent advances in evolutionary biology, prominent scholars return to the question posed in a pathbreaking book: how evolution itself evolved. In 1995, John Maynard Smith and Eörs Szathmáry published their influential book The Major Transitions in Evolution. The "transitions" that Maynard Smith and Szathmáry chose to describe all constituted major changes in the kinds of organisms that existed but, most important, these events also transformed the evolutionary process itself. The evolution of new levels of biological organization, such as chromosomes, cells, multicelled organisms, and complex social groups radically changed the kinds of individuals natural selection could act upon. Many of these events also produced revolutionary changes in the process of inheritance, by expanding the range and fidelity of transmission, establishing new inheritance channels, and developing more open-ended sources of variation. Maynard Smith and Szathmáry had planned a major revision of their work, but the death of Maynard Smith in 2004 prevented this. In this volume, prominent scholars (including Szathmáry himself) reconsider and extend the earlier book's themes in light of recent developments in evolutionary biology. The contributors discuss different frameworks for understanding macroevolution, prokaryote evolution (the study of which has been aided by developments in molecular biology), and the complex evolution of multicellularity.

Transition metal ions in biological systems are of interest in biology, biochemistry, chemistry, medicine, and physics. Scien tists with rather different viewpoints, employing many methods, have contributed to this area. A concise review of the current state of the field will, to some extent, reflect the special knowledge of the person writing it - in this case application of physical methods to the investigation of metal coordination. x ray diffraction is one of the most important of these methods, but a useful treatment of X-ray structure analysis would be com parable in size with and beyond the scope of the monograph. Many results of X-ray diffraction studies are, of course, presented. Electron paramagnetic resonance spectroscopy has played a major part in the rapid advance in knowledge of the electronic struc tures of transition metal ions in biological systems. More gener ally, measurements involving light, microwaves, and magnetic fields are capable of producing much new information, and the required instrumentation is available at most research institu tions. Therefore light absorption and paramagnetic resonance are treated in depth. The principles described in the latter discus sions are broadly applicable, for example to the promising tech niques of X-ray spectroscopy (utilizing synchrotron radiation) and lanthanide-perturbed, very high-resolution nuclear magnetic resonance spectroscopy.

Phase transitions--changes between different states of organization in a complex system--have long helped to explain physics concepts, such as why water freezes into a solid or boils to become a gas. How might phase transitions shed light on important problems in biological and ecological complex systems? Exploring the origins and implications of sudden changes in nature and society, Phase Transitions examines different dynamical behaviors in a broad range of complex systems. Using a compelling set of examples, from gene networks and ant colonies to human language and the degradation of diverse ecosystems, the book illustrates the power of simple models to reveal how phase transitions occur. Introductory chapters provide the critical concepts and the simplest mathematical techniques required to study phase transitions. In a series of example-driven chapters, Ricard Solé shows how such concepts and techniques can be applied to the analysis and prediction of complex system behavior, including the origins of life, viral replication, epidemics, language evolution, and the emergence and breakdown of societies. Written at an undergraduate mathematical level, this book provides the essential theoretical tools and foundations required to develop basic models to explain collective phase transitions for a wide variety of ecosystems.
