Tedford have spent the past 20 years studying the evolutionary history of the family Canidae. Both are well known for having established the modern framework for the evolutionary relationship of canids. Combining their research with Mauricio Ant�n's impeccable reconstructions of both extinct and extant species, Wang and Tedford present a remarkably detailed and nuanced portrait of the origin and evolution of canids over the past 40 million years.The authors cull their history from the most recent scientific research conducted on the vast collections of the American Museum of Natural History and other leading institutions. The fossil record of the Canidae, particularly those from their birth place in North America, are the strongest of their kind among known groups of carnivorans. Such a wonderfully detailed evolutionary history provides access to a natural history that is not possible with many other groups of carnivorans.With their rich fossil record, diverse adaptations to various environments, and different predatory specializations, canids are an ideal model organism for the mapping of predator behavior and morphological specializations. They also offer an excellent contrast to felids, which remain entrenched in extreme predatory specializations. The innovative illustrated approach in this book is the perfect accompaniment to an extremely important branch of animal and fossil study. It transforms the science of paleontology into a thrilling visual experience and provides an unprecedented reference for anyone fascinated by dogs.

    Perhaps ideas have us. After all, ideas do appear to have a life of their own. And it is they, not us, that benefit most when they are spread. Many biologists have already come to the opinion that our genes are selfish entities, tricking us into helping them to reproduce. Is it the same with our ideas?     Jonnie Hughes, a science writer and documentary filmmaker, investigates the evolution of ideas in order to find out. Adopting the role of a cultural Charles Darwin, Hughes heads off, with his brother in tow, across the Midwest to observe firsthand the natural history of ideas—the patterns of their variation, inheritance, and selection in the cultural landscape. In place of Darwin’s oceanic islands, Hughes visits the “mind islands” of Native American tribes. Instead of finches, Hughes searches for signs of natural selection among the tepees.     With a knack for finding the humor in the quirks of the American cultural landscape, Hughes takes us on a tour from the Mall of America in Minneapolis to what he calls the “maul” of America—Custer’s last stand—stopping at road-sides and discoursing on sandwiches, the shape of cowboy hats, the evolution of barn roofs, the wording of jokes, the wearing of moustaches, and, of course, the telling features from tepees of different tribes. Original, witty, and engaging, On the Origin of Tepees offers a fresh way of understanding both our ideas and ourselves.

    It infected nearly one-third of the world’s population and killed ten percent of those it struck. In its wake, schools and businesses closed, hospitals became overwhelmed, and the sick spilled out into makeshift care centers in public spaces. Policemen, public transportation workers, and everyday citizens in face masks were a common—and eerie—sight. Yet, discussion of this global pandemic often takes a backseat to World War I and other contemporary events.

    The latest studies are revealing exciting new discoveries, such as how the DNA and related chemical compounds in our cells work together to direct the processes of life. Scientists are not only unraveling how life evolved in the ancient past, but are also finding the keys to creating a healthier future.  How does the minuscule chemical cluster in each of our 100 trillion cells accomplish the amazing feat of creating and maintaining our bodies? Frank Ryan, a physician and an evolutionary biologist, describes the complex ways in which the genome operates as a holistic system and not solely through genes coding for proteins—the building blocks of life. Also involved are elaborate switching mechanisms that regulate and control portions of our DNA, as well as the interplay of retroviruses and bacteria.This groundbreaking book explains that we are on the cusp of an amazing era of disease treatment and eradication.

    They force us to confront a fundamental biological problem: how can something as large and complex as a human body organize itself from the simplicity of a fertilized egg? A convergence of ideas from embryology, genetics, physics, networks, and control theory has begun to provide real answers. Based on the central principle of 'adaptive self-organization, ' it explains how the interactions of many cells, and of the tiny molecular machines that run them, can organize tissue structures vastly larger than themselves, correcting errors as they go along and creating new layers of complexity where there were none before.Life Unfolding tells the story of human development from egg to adult, from this perspective, showing how our whole understanding of how we come to be has been transformed in recent years. Highlighting how embryological knowledge is being used to understand why bodies age and fail, Jamie A. Daviesexplores the profound and fascinating impacts of our newfound knowledge.

    r/K Theory examines how all populations tend to adopt one of two psychologies as a means of adapting their behavior to the presence or absence of environmental resources. The two strategies, termed r and K, each correlate perfectly with the psychologies underlying Liberalism and Conservatism.One strategy, named the r-strategy, imbues those who are programmed with it to be averse to all peer on peer competition, embrace promiscuity, embrace single parenting, and support early onset sexual activity in youth. Obviously, this mirrors the Liberal philosophy's aversion to individual Darwinian competitions such as capitalism and self defense with firearms, as well as group competitions such as war. Likewise, Liberalism is tolerant of promiscuity, tolerant of single parenting, and more prone to support early sex education for children and the sexualization of cultural influences. Designed to exploit a plethora of resources, one will often find this r-type strategy embodied within prey species, where predation has lowered the population's numbers, and thereby increased the resources available to it's individuals.The other strategy, termed the K-strategy, imbues those who pursue it with a fierce competitiveness, as well as tendencies towards abstinence until monogamy, two-parent parenting, and delaying sexual activity until later in life. Obviously, this mirrors Conservatism's acceptance of all sorts of competitive social schemes, from free market capitalism, to war, to individuals owning and carrying private weapons for self defense. Conservatives also tend to favor abstinence until monogamy, two parent parenting with an emphasis upon "family values," and children being shielded from any sexualized stimuli until later in life. This strategy is found most commonly in species which lack predation, and whose population's have grown to the point individuals must compete with each other for the limited environmental resources that they are rapidly running out of.Meticulously substantiated with the latest research in fields from neurobiology to human behavioral ecology, this work offers an unprecedented view into not just what governs our political battles, but why these battles have arisen within our species in the first place. From showing how these two strategies adapt in other more complex species in nature, to examining what genetic and neurostructural mechanisms may produce these divergences between individuals, to showing what this theory indicates our future may hold, this work is the most thorough analysis to date of just why we have two political ideologies, why they will never agree, and why we will tend to become even more partisan in the future.

    This brief, accessible introduction describes some of the most interesting research in the field and also enables readers to implement and experiment with genetic algorithms on their own. It focuses in depth on a small set of important and interesting topics--particularly in machine learning, scientific modeling, and artificial life--and reviews a broad span of research, including the work of Mitchell and her colleagues.The descriptions of applications and modeling projects stretch beyond the strict boundaries of computer science to include dynamical systems theory, game theory, molecular biology, ecology, evolutionary biology, and population genetics, underscoring the exciting general purpose nature of genetic algorithms as search methods that can be employed across disciplines.An Introduction to Genetic Algorithms is accessible to students and researchers in any scientific discipline. It includes many thought and computer exercises that build on and reinforce the reader's understanding of the text. The first chapter introduces genetic algorithms and their terminology and describes two provocative applications in detail. The second and third chapters look at the use of genetic algorithms in machine learning (computer programs, data analysis and prediction, neural networks) and in scientific models (interactions among learning, evolution, and culture; sexual selection; ecosystems; evolutionary activity). Several approaches to the theory of genetic algorithms are discussed in depth in the fourth chapter. The fifth chapter takes up implementation, and the last chapter poses some currently unanswered questions and surveys prospects for the future of evolutionary computation.

    How is it that Homo sapiens formed such a special relationship with what, on the face of it, is a most unlikely ally? It is more than just a story of domestication but an astonishing example of the co-evolution of two species, man and wolf, to each others' mutual benefit. This co-evolution was a vital step in helping Homo sapiens overcome competition from other human species and to expand in numbers from relative obscurity on the margins towards the overwhelming numerical superiority and influence that we enjoy today. The book draws on the rich scientific detail of the genomes, both dog and human, that has accumulated over the past two decades. In each case we see a clear pattern of the origins of both species, resolving questions that have puzzled scientists for centuries. Sykes explores the breadth of this `special relationship' between man and dog. We know that dogs descend from wolves. We know that their domesticated descendants form close bonds with ourselves and there are a multitude of theories to account for our compatible social organisations. But to a geneticist, this is nowhere near powerful enough to explain this most peculiar situation. Many theories explore what it was that propelled Homo sapiens from the position of a scarce, medium-sized primate to the position of complete domination that we enjoy today. The ability to control fire, the evolution of language and the invention of agriculture are three prominent examples. Sykes crucially adds a fourth: our transformation of the wolf into the multi-purpose helpmate that is the dog. We owe our dominance and our survival to the dog.
