In Bite, zoologist Bill Schutt makes a surprising case: it is teeth that are responsible for the long-term success of vertebrates. The appearance of teeth, roughly half a billion years ago, was an adaptation that allowed animals with backbones, such as fish, amphibians, reptiles, birds, dinosaurs and mammals—including us—to chow down in pretty much every conceivable environment.

Mary Anning was only 12 years old when, in 1811, she discovered the first dinosaur skeleton - of an ichthyosaur - while fossil hunting on the cliffs of Lyme Regis, England. Until Mary's incredible discovery, it was widely believed that animals did not become extinct.

Asserting that religious creeds and philosophical questions can be reduced to purely genetic and evolutionary components, and that the human body and mind have a physical base obedient to the laws of physics and chemistry, Genesis demonstrates that the only way for us to fully understand human behavior is to study the evolutionary histories of nonhuman species. Of these, Wilson demonstrates that at least 17 - among them the African naked mole rat and the sponge-dwelling shrimp - have been found to have advanced societies based on altruism and cooperation.

In this book, E. Fuller Torrey draws on cutting-edge neuroscience research to propose a startling answer to the ultimate question. Evolving Brains, Emerging Gods locates the origin of gods within the human brain, arguing that religious belief is a by-product of evolution. Based on an idea originally proposed by Charles Darwin, Torrey marshals evidence that the emergence of gods was an incidental consequence of several evolutionary factors.

No hay ningún plan de alimentación funcional para todo el mundo: lo que a unos les sienta bien, a otros puede hacerles daño. ¿Cómo se explica? Por el código genético, que es absolutamente único en cada persona.

In these lively and fascinating essays, scientists from around the world weigh in on the latest advances in the search for intelligent life in the universe and discuss just what that might look like. Since 2000, science has seen a surge in data and interest on several fronts related to ET (extraterrestrials); AI (artificial intelligence); and SETI (search for extraterrestrial intelligence). The debate has intensified over whether life exists outside our solar system, what that life would look like, and whether we'll ever make contact.

Whether looking at intelligence or emotion, cognition or behavior, science has continued to tell us that men and women are fundamentally different. Biologists claim that women are better suited to raising families or are, more gently, uniquely empathetic. Men, on the other hand, continue to be described as excelling at tasks that require logic, spatial reasoning, and motor skills. But a huge wave of research is now revealing an alternative version of what we thought we knew.

In this classic volume, Peter Matthiessen exquisitely combines nature and travel writing to bring East Africa to vivid life. He skillfully and magically portrays the sights, scenes, and people he observed firsthand in several trips over the course of a dozen years: the daily lives of herdsmen and hunter-gatherers; the drama of the predator kills; the hundreds of exotic animals; the breathtaking landscapes; the area's turbulent natural, political, and social histories; and more.

What is life? In this penetrating and wide-ranging book, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it lacks a name; it is a domain where biology, computing, logic, chemistry, quantum physics, and nanotechnology intersect.

In The Language Puzzle, renowned archaeologist Steven Mithen puts forward a groundbreaking new account of the origins of language. Scientists have gained new insights into the first humans of 2.8 million years ago, and how numerous species flourished but only one, Homo sapiens, survives today. Drawing from this work and synthesizing research across archaeology, psychology, linguistics, genetics, and more, Mithen details a step-by-step explanation of how our human ancestors transitioned from apelike calls to words, and from words to language as we use it today.

First coined by Richard Dawkins in The Selfish Gene, a meme is any idea, behavior, or skill that can be transferred from one person to another by imitation. Susan Blackmore shows that once our distant ancestors acquired the crucial ability to imitate, a second kind of natural selection began, a survival of the fittest amongst competing ideas and behaviors. Ideas and behaviors that proved most adaptive-making tools, for example, or using language - survived and flourished, replicating themselves in as many minds as possible.

Were dinosaurs really dumber than lizards? Why, after all, are roughly the same number of men and women born into the world? What led the famous Dr. Down to his theory of mongolism, and its racist residue? What do the panda's magical "thumb" and the sea turtle's perilous migration tell us about imperfections that prove the evolutionary rule? The wonders and mysteries of evolutionary biology are elegantly explored in these and other essays by the celebrated natural history writer Stephen Jay Gould.

In The Genealogical Adam and Eve, S. Joshua Swamidass tests a scientific hypothesis: What if the traditional account is somehow true, with the origins of Adam and Eve taking place alongside evolution? Building on well-established but overlooked science, Swamidass explains how it's possible for Adam and Eve to be rightly identified as the ancestors of everyone.

In 1994, a team led by fossil-hunting legend Tim White—"the Steve Jobs of paleoanthropology"—uncovered the bones of a human ancestor in Ethiopia's Afar region. The findings challenged many assumptions about human evolution and repudiated a half-century of paleoanthropological orthodoxy. An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must-listen for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.

Edward Larson's classic, Summer for the Gods, received the Pulitzer Prize in History in 1998 and is the single most authoritative account of a pivotal event whose combatants remain at odds in school districts and courtrooms. For this edition Larson has added a new preface that assesses the state of the battle between creationism and evolution and points the way to how it might potentially be resolved.

Everywhere there are characteristics of animals that do not want to fit into the theory of evolution anywhere. And man? Are we really the most adapted life-form on this planet? Today, more and more scientists who contradict the previous theory of evolution speak out. The theory fits the changes within the species, but it can no longer be reconciled with the inner workings of the cell. Some other influence that has so far escaped us is affecting evolution. It is called "Intelligent Design." Intelligent planning is suspected behind this.

In the best-selling and critically acclaimed Darwin on Trial and Reason in the Balance, Phillip Johnson took on the academic elites and exposed the misleading claims of evolutionary naturalism. Defeating Darwinism by Opening Minds provides a new and powerful treatment of these issues for high-school students, parents, teachers, pastors, youth advisers, and ordinary listeners. Johnson aims not just to defeat a bad theory, but to defeat it in the right way - by opening minds to the truth.

In this innovative celebration of diversity and affirmation of individuality in animals and humans, Joan Roughgarden challenges accepted wisdom about gender identity and sexual orientation. A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science--and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. A new preface shows how this witty, playful, and daring book has revolutionized our understanding of sexuality.

It is now known that we live in a galaxy with more planets than stars. The Milky Way alone encompasses 30 trillion potential home planets. Scientists Trefil and Summers bring listeners on a marvelous experimental voyage through the possibilities of life-unlike anything we have experienced so far - that could exist on planets outside our own solar system.

Homo Deus explores the projects, dreams, and nightmares that will shape the 21st century - from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is Homo Deus.
