Book Description
The history of life is a nearly four billion year old story of transformative change. This change ranges from dramatic macroscopic innovations such as the evolution of wings or eyes, to a myriad of molecular changes that form the basis of macroscopic innovations. We are familiar with many examples of innovations (qualitatively new phenotypes that provide a critical benefit) but have no systematic understanding of the principles that allow organisms to innovate. This book proposes several such principles as the basis of a theory of innovation, integrating recent knowledge about complex molecular phenotypes with more traditional Darwinian thinking. Central to the book are genotype networks: vast sets of connected genotypes that exist in metabolism and regulatory circuitry, as well as in protein and RNA molecules. The theory can successfully unify innovations that occur at different levels of organization. It captures known features of biological innovation, including the fact that many innovations occur multiple times independently, and that they combine existing parts of a system to new purposes. It also argues that environmental change is important to create biological systems that are both complex and robust, and shows how such robustness can facilitate innovation. Beyond that, the theory can reconcile neutralism and selectionism, as well as explain the role of phenotypic plasticity, gene duplication, recombination, and cryptic variation in innovation. Finally, its principles can be applied to technological innovation, and thus open to human engineering endeavours the powerful principles that have allowed life's spectacular success.

Book Description
Evolutionary innovations—the bony skeleton of vertebrates, avian flight, or the insect pollination system of angiosperms, for example—have in recent years become the focus of much fertile new research in evolutionary biology. Innovations may hold the keys to understanding why whole new groups of organisms evolve or, conversely, why groups of organisms become extinct. This volume brings together contributors from the fields of morphology, genetics, embryology, physiology, and paleontology to present research on evolutionary innovations and to suggest directions for further work. The topics covered include the plurality of evolutionary innovations, patterns and processes at different hierarchical levels, evolutionary genetics of adaptations, heterochrony and other mechanisms of radical evolutionary change in early development, developmental mechanisms at the origin of morphological novelty, the evolution of morphological variation patterns, functional design and its punctuated products, plausibility and testability in assessing the consequences of evolutionary innovations, paradigms and pitfalls of studying physiological evolution, polyphyletic constructional breakthroughs in fossil and extant species, ecology of evolutionary innovations in the fossil record.

Book Description
A major synthesis of homology, written by a top researcher in the field Homology—a similar trait shared by different species and derived from common ancestry, such as a seal's fin and a bird’s wing—is one of the most fundamental yet challenging concepts in evolutionary biology. This groundbreaking book provides the first mechanistically based theory of what homology is and how it arises in evolution. Günter Wagner, one of the preeminent researchers in the field, argues that homology, or character identity, can be explained through the historical continuity of character identity networks—that is, the gene regulatory networks that enable differential gene expression. He shows how character identity is independent of the form and function of the character itself because the same network can activate different effector genes and thus control the development of different shapes, sizes, and qualities of the character. Demonstrating how this theoretical model can provide a foundation for understanding the evolutionary origin of novel characters, Wagner applies it to the origin and evolution of specific systems, such as cell types; skin, hair, and feathers; limbs and digits; and flowers. The first major synthesis of homology to be published in decades, Homology, Genes, and Evolutionary Innovation reveals how a mechanistically based theory can serve as a unifying concept for any branch of science concerned with the structure and development of organisms, and how it can help explain major transitions in evolution and broad patterns of biological diversity.

Book Description
This important book addresses how long term and large scale shifts from one socio-technical system to another come about, using insights from evolutionary economics, sociology of technology and innovation studies. These major changes involve not just technological changes, but also changes in markets, regulation, culture, industrial networks and infrastructure. The book develops a multi-level perspective, arguing that transitions take place through the alignment of multiple processes at three levels: niche, regime and landscape. This perspective is illustrated by detailed historical case studies: the transition from sailing ships to steamships, the transition from horse-and-carriage to automobiles and the transition from propeller-piston engine aircraft to turbojets. This book will be of great interest to researchers in innovation studies, evolutionary economics, sociology of technology and environmental studies. It will also be useful for policy makers involved in long-term sustainability and systems transitions issues.

Book Description
Plant breeders have long sought technologies to extend human control over nature. Early in the twentieth century, this led some to experiment with startlingly strange tools like x-ray machines, chromosome-altering chemicals, and radioactive elements. Contemporary reports celebrated these mutation-inducing methods as ways of generating variation in plants on demand. Speeding up evolution, they imagined, would allow breeders to genetically engineer crops and flowers to order. Creating a new food crop or garden flower would soon be as straightforward as innovating any other modern industrial product. In Evolution Made to Order, Helen Anne Curry traces the history of America’s pursuit of tools that could intervene in evolution. An immersive journey through the scientific and social worlds of midcentury genetics and plant breeding and a compelling exploration of American cultures of innovation, Evolution Made to Order provides vital historical context for current worldwide ethical and policy debates over genetic engineering.

Book Description
The studies of evolutionary biology and of human history face the same kinds of problems and deal with the same processes. Both disciplines deal with similar questions in similar ways, but do the methods used produce comparable knowledge, and are the differences and similarities between these disciplines real? This book examines the philosophy of historical and evolutionary studies; the objectivity and meanings of human and evolutionary histories; the evolutionary approaches to and the anlysis of history, historical approaches, and utilization of evolution; the logic of historical and evolutionary thinking and explanations; the identification of similarities, differences, and common problems of evolutionary biology and history; and what constitutes the major historical and evolutionary events.

The motivation behind this book is the desire to integrate complexity theory into economic models of technological evolution. By means of developing an evolutionary model of complex technological systems, the book contributes to the neo-Schumpetarian literature on innovation, diffusion and technological paradigms.
