Book Description
“It is not only the species that change evolutionarily through interactions . . . the interactions themselves also change.” Thus states John N. Thompson in the foreword to Interaction and Coevolution, the first title in his series of books exploring the relentless nature of evolution and the processes that shape the web of life. Originally published in 1982 more as an idea piece—an early attempt to synthesize then academically distinct but logically linked strands of ecological thought and to suggest avenues for further research—than as a data-driven monograph, Interaction and Coevolution would go on to be considered a landmark study that pointed to the beginning of a new discipline. Through chapters on antagonism, mutualism, and the effects of these interactions on populations, speciation, and community structure, Thompson seeks to explain not only how interactions differ in the selection pressures they exert on species, but also when interactions are most likely to lead to coevolution. In this era of climate change and swiftly transforming environments, the ideas Thompson puts forward in Interaction and Coevolution are more relevant than ever before.

Book Description
Coevolution—reciprocal evolutionary change in interacting species driven by natural selection—is one of the most important ecological and genetic processes organizing the earth's biodiversity: most plants and animals require coevolved interactions with other species to survive and reproduce. The Geographic Mosaic of Coevolution analyzes how the biology of species provides the raw material for long-term coevolution, evaluates how local coadaptation forms the basic module of coevolutionary change, and explores how the coevolutionary process reshapes locally coevolving interactions across the earth's constantly changing landscapes. Picking up where his influential The Coevolutionary Process left off, John N. Thompsonsynthesizes the state of a rapidly developing science that integrates approaches from evolutionary ecology, population genetics, phylogeography, systematics, evolutionary biochemistry and physiology, and molecular biology. Using models, data, and hypotheses to develop a complete conceptual framework, Thompson also draws on examples from a wide range of taxa and environments, illustrating the expanding breadth and depth of research in coevolutionary biology.

Book Description
Traditional ecological approaches to species evolution have frequently studied too few species, relatively small areas, and relatively short time spans. In The Coevolutionary Process, John N. Thompson advances a new conceptual approach to the evolution of species interactions—the geographic mosaic theory of coevolution. Thompson demonstrates how an integrated study of life histories, genetics, and the geographic structure of populations yields a broader understanding of coevolution, or the development of reciprocal adaptations and specializations in interdependent species. Using examples of species interactions from an enormous range of taxa, Thompson examines how and when extreme specialization evolves in interdependent species and how geographic differences in specialization, adaptation, and the outcomes of interactions shape coevolution. Through the geographic mosaic theory, Thompson bridges the gap between the study of specialization and coevolution in local communities and the study of broader patterns seen in comparisons of the phylogenies of interacting species.

Book Description
Ants are probably the most dominant insect group on Earth, representing ten to fifteen percent of animal biomass in terrestrial ecosystems. Flowering plants, meanwhile, owe their evolutionary success to an array of interspecific interactions—such as pollination, seed dispersal, and herbivory—that have helped to shape their great diversity. The Ecology and Evolution of Ant-Plant Interactions brings together findings from the scientific literature on the coevolution of ants and plants to provide a better understanding of the unparalleled success of these two remarkable groups, of interspecific interactions in general, and ultimately of terrestrial biological communities. The Ecology and Evolution of Ant-Plant Interactions synthesizes the dynamics of ant-plant interactions, including the sources of variation in their outcomes. Victor Rico-Gray and Paulo S. Oliveira capture both the emerging appreciation of the importance of these interactions within ecosystems and the developing approaches that place studies of these interactions into a broader ecological and evolutionary context. The collaboration of two internationally renowned scientists, The Ecology and Evolution of Ant-Plant Interactions will become a standard reference for understanding the complex interactions between these two taxa.

Book Description
Charles Darwin's "On the Origins of Species" had two principal goals: to show that species had not been separately created and to show that natural selection had been the main force behind their proliferation and descent from common ancestors. In "Coevolution," the author proposes a powerful new theory of cultural evolution--that is, of the descent with modification of the shared conceptual systems we call "cultures"--that is parallel in many ways to Darwin's theory of organic evolution. The author suggests that a process of cultural selection, or preservation by preference, driven chiefly by choice or imposition depending on the circumstances, has been the main but not exclusive force of cultural change. He shows that this process gives rise to five major patterns or "modes" in which cultural change is at odds with genetic change. Each of the five modes is discussed in some detail and its existence confirmed through one or more case studies chosen for their heuristic value, the robustness of their data, and their broader implications. But "Coevolution" predicts not simply the existence of the five modes of gene-culture relations; it also predicts their relative importance in the ongoing dynamics of cultural change in particular cases. The case studies themselves are lucid and innovative reexaminations of an array of oft-pondered anthropological topics--plural marriage, sickle-cell anemia, basic color terms, adult lactose absorption, incest taboos, headhunting, and cannibalism. In a general case, the author's goal is to demonstrate that an evolutionary analysis of both genes and culture has much to contribute to our understanding of human diversity, particularly behavioral diversity, and thus to the resolution of age-old questions about nature and nurture, genes and culture.

Book Description
Should digital technology be viewed as a new life form, sharing our ecosystem and coevolving with us? Are humans defining technology, or is technology defining humans? In this book, Edward Ashford Lee considers the case that we are less in control of the trajectory of technology than we think. It shapes us as much as we shape it, and it may be more defensible to think of technology as the result of a Darwinian coevolution than the result of top-down intelligent design. Richard Dawkins famously said that a chicken is an egg's way of making another egg. Is a human a computer's way of making another computer? To understand this question requires a deep dive into how evolution works, how humans are different from computers, and how the way technology develops resembles the emergence of a new life form on our planet. Lee presents the case for considering digital beings to be living, then offers counterarguments. What we humans do with our minds is more than computation, and what digital systems do—be teleported at the speed of light, backed up, and restored—may never be possible for humans. To believe that we are simply computations, he argues, is a “dataist” faith and scientifically indefensible. Digital beings depend on humans—and humans depend on digital beings. More likely than a planetary wipe-out of humanity is an ongoing, symbiotic coevolution of culture and technology.

Book Description
At a glance, most species seem adapted to the environment in which they live. Yet species relentlessly evolve, and populations within species evolve in different ways. Evolution, as it turns out, is much more dynamic than biologists realized just a few decades ago. In Relentless Evolution, John N. Thompson explores why adaptive evolution never ceases and why natural selection acts on species in so many different ways. Thompson presents a view of life in which ongoing evolution is essential and inevitable. Each chapter focuses on one of the major problems in adaptive evolution: How fast is evolution? How strong is natural selection? How do species co-opt the genomes of other species as they adapt? Why does adaptive evolution sometimes lead to more, rather than less, genetic variation within populations? How does the process of adaptation drive the evolution of new species? How does coevolution among species continually reshape the web of life? And, more generally, how are our views of adaptive evolution changing? Relentless Evolution draws on studies of all the major forms of life—from microbes that evolve in microcosms within a few weeks to plants and animals that sometimes evolve in detectable ways within a few decades. It shows evolution not as a slow and stately process, but rather as a continual and sometimes frenetic process that favors yet more evolutionary change.

Book Description
Darwin’s nineteenth-century writings laid the foundations for modern studies of evolution, and theoretical developments in the mid-twentieth century fostered the Modern Synthesis. Since that time, a great deal of new biological knowledge has been generated, including details of the genetic code, lateral gene transfer, and developmental constraints. Our improved understanding of these and many other phenomena have been working their way into evolutionary theory, changing it and improving its correspondence with evolution in nature. And while the study of evolution is thriving both as a basic science to understand the world and in its applications in agriculture, medicine, and public health, the broad scope of evolution—operating across genes, whole organisms, clades, and ecosystems—presents a significant challenge for researchers seeking to integrate abundant new data and content into a general theory of evolution. This book gives us that framework and synthesis for the twenty-first century. The Theory of Evolution presents a series of chapters by experts seeking this integration by addressing the current state of affairs across numerous fields within evolutionary biology, ranging from biogeography to multilevel selection, speciation, and macroevolutionary theory. By presenting current syntheses of evolution’s theoretical foundations and their growth in light of new datasets and analyses, this collection will enhance future research and understanding.

Book Description
For many of us, the mere mention of lice forces an immediate hand to the head, and recollection of childhood experience with nits, special shampoos, etc. But for a certain breed of biologist, lice make for fascinating scientific fodder, especially so if you are a scientist studying coevolution. Lice and their various hosts--humans, birds, etc. --provide a stunning example of the ecology of species coevolution. This system of complex symbiotic relations reveals some of the ecological principles of coevolutionary relations, one of the most exciting areas of research in evolutionary biology of recent. This work provides an introduction to coevolutionary concepts and approaches, ranging from microevolutionary (ecological) time to macroevolutionary time. The authors then use the system of parasitic lice and their hosts to illustrate some of these different concepts and approaches. They draw examples from a variety of other coevolving systems for comparative purposes, and emphasize the integration of cophylogenetic, comparative, and experimental data in testing coevolutionary hypotheses. Because lice are permanent parasites that spend their entire lifecycle on the body of the host, their close ecological association makes them ideally suited for this kind of synthetic overview of coevolution."

Book Description
Over the past decade, ecologists have increasingly embraced phylogenetics, the study of evolutionary relationships among species. As a result, they have come to discover the field’s power to illuminate present ecological patterns and processes. Ecologists are now investigating whether phylogenetic diversity is a better measure of ecosystem health than more traditional metrics like species diversity, whether it can predict the future structure and function of communities and ecosystems, and whether conservationists might prioritize it when formulating conservation plans. In Phylogenetic Ecology, Nathan G. Swenson synthesizes this nascent field’s major conceptual, methodological, and empirical developments to provide students and practicing ecologists with a foundational overview. Along the way, he highlights those realms of phylogenetic ecology that will likely increase in relevance—such as the burgeoning subfield of phylogenomics—and shows how ecologists might lean on these new perspectives to inform their research programs.
