The stewards of Earth, these organisms transformed the chemistry of our planet to make it habitable for plants, animals, and us. Life's Engines takes readers deep into the microscopic world to explore how these marvelous creatures made life on Earth possible--and how human life today would cease to exist without them.Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built--and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.A vibrantly entertaining book about the microbes that support our very existence, Life's Engines will inspire wonder about these elegantly complex nanomachines that have driven life since its origin. It also issues a timely warning about the dangers of tinkering with that machinery to make it more "efficient" at meeting the ever-growing demands of humans in the coming century.

    Barash, there are even more things that we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personalaspects of being human.Homo Mysterious examines a number of these evolutionary mysteries, exploring things that we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse. Why do women experience orgasm? Why do men have a shorterlifespan than women? Why does homosexuality exist? Why does religion exist in virtually every culture? Why do we have a fondness for the arts? Why do we have such large brains? And why does consciousness exist? Readers are plunged into an ocean of unknowns--the blank spots on the human evolutionarymap, the terra incognita of our own species--and are introduced to the major hypotheses that currently occupy scientists who are attempting to unravel each puzzle (including some solutions proposed here for the first time). Throughout the book, readers are invited to share the thrill of science atits cutting edge, a place where we know what we don't know, and, moreover, where we know enough to come up with some compelling and seductive explanations.Homo Mysterious is a guide to creative thought and future explorations, based on the best, most current thinking by evolutionary scientists. It captures the allure of the not-yet-known for those interested in stretching their scientific imaginations.

    Here is a delightfully entertaining and enlightening look at the unique sex lives of humans.

    Paul Colinvaux takes a penetrating look at the science of ecology, bringing to his subject both profound knowledge and an enthusiasm that will encourage a greater understanding of the environment and of the efforts of those who seek to preserve it.

    Our bodies are a quirky mix of new and old, with strokes of genius alongside glitches and imperfections which are all inherited from distant ancestors. Our development and evolutionary past explains why, as embryos, we have what look like gills, and as adults we suffer from back pain.This is a tale of discovery, not only exploring why and how we have developed as we have, but also looking at the history of our anatomical understanding. It combines the remarkable skills and qualifications Alice Roberts has as a doctor, anatomist, osteoarchaeologist and writer. Above all, she has a rare ability to make science accessible, relevant and interesting to mainstream audiences and readers.

The sixth edition boasts the next generation of media integration including Gen CD-X (student CD-ROM and Companion Website).

    Though the process obeyed all the rules of chemistry and physics, the details of that original event pose as deep a mystery as any facing science. How did non-living chemicals become alive? While the question is (deceivingly) simple, the answers are unquestionably complex. Science inevitably plays a key role in any discussion of life's origins, dealing less with the question of why life appeared on Earth than with where, when, and how it emerged on the blasted, barren face of our primitive planet. Astrobiologist Robert Hazen has spent many years dealing with the fundamental questions of life's genesis. As an active research scientist, he is down deep in all the messy details that science has to offer on the subject, tracing the inexorable sequence of events that led to the complicated interactions of carbonbased molecules. As he takes us through the astounding process of emergence, we are witness to the first tentative steps toward life?from the unfathomable abundance of carbon biomolecules synthesized in the black vacuum of space to the surface of the Earth to deep within our planet's restless crust. We are privy to the breathtaking drama that rapidly unfolds as life prevails. The theory of emergence is poised to answer a multitude of questions?even as it raises the possibility that natural processes exist beyond what we now know, perhaps beyond what we even comprehend. Genesis tells the tale of transforming scientific advances in our quest for life's origins. Written with grace, beauty, and authority, it goes directly to the heart of who we are and why we are here.

    But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

    His theories on the evolutionary tensions between parent and offspring, sibling and sibling, man and woman, friend and friend, and a person and himself or herself have not only revolutionized genetics and evolutionary biology but have influenced disciplines from medicine and the social sciences to history, economics, and literary studies. But unlike other renowned scientists, Trivers has spent time behind bars, drove a getaway car for Huey P. Newton, and founded an armed group in Jamaica to protect gay men from mob violence. Now, in the entertaining tradition of Surely You're Joking Mr. Feynman, Trivers tell us in his inimitable voice about the inimitable life behind the revolutionary science. He comments with irreverent wit and penetrating insight on everything from American racism to the history of psychiatry to who killed Peter Tosh, musical heir to Bob Marley. Sprinkled with anecdotes about such luminaries as Richard Dawkins and Stephen Jay Gould, and with photographs throughout, this volume is sure to enlighten and entertain anyone with an interest in science, the human condition, or the nature of creative genius. PRAISE FOR WILD LIFE"To call Robert Trivers an acclaimed biologist is an understatement akin to calling the late Richard Feynman a popular professor of physics." -- PSYCHOLOGY TODAY"Who would have guessed that arguably today’s most original thinker in evolutionary theory could possibly have led the extraordinary life Robert Trivers recounts in these pages. We are taken on a wild trip from inspired meditations on the biology of self deception, through a steamy Jamaican underworld, to Black Panthers in California, to frank appraisals of distinguished or over-rated scientists, the whole adding up to a disarmingly frank and utterly unique memoir of a rollercoaster of a life. -- RICHARD DAWKINS, bestselling author of The Selfish Gene and The God Delusion“Robert Trivers is not just a brilliant evolutionary thinker but a world-class raconteur, adventurer, kibitzer, people-watcher, jester, and provocateur. This memoir is filled with sharp and hilarious observations about the living world, not least a certain species of hairless primate, not least a certain member of that species named Robert Trivers.” – STEVEN PINKER,best-selling author of How the Mind Works and The Better Angels of Our Nature: Why Violence Has Declined“It would not be hyperbole to say that Robert Trivers is one of the most important evolutionary theorists since Charles Darwin. But contrary to the image most people have of theoretical scientists as stodgy intellectuals holed up in their offices buried in paper, Trivers' memoir reveals a man whose life has been wild in every sense of the word. A lust for life doesn’t begin to sum up a career devoted to truth, courage, and the audacity to think what no one else has thought, and to act in ways few others would dare (you’ll even learn how to defend yourself in a knife fight). If that were not enough, Trivers is witty, clever, and compassionate. This book is destined to become a classic in scientific autobiography." -- MICHAEL SHERMER, Editor in Chief, The SkepticABOUT THE AUTHORRobert Trivers is a professor of anthropology and biological sciences at Rutgers University.

    The Birder's Handbook is the first of its kind: a portable library of fascinating information not included in your identification guide. For each of the 646 species of birds that breed in North America, The Birder's Handbook will tell you at a glance: * Where the bird nests, and which sex(es) build(s) the nest;* How many eggs the bird lays, what they look like, which patent incubates and for how long, and how the young are cared for;* Food preferences and foraging habits.You will also find information about displays and mating, wintering, conservation status, and much more. In addition, The Birder's Handbook contains some 250 short essays covering all aspects of avian natural history.

    In 1971 he was discovered on the remote Galapagos island of Pinta, from which tortoises had supposedly been exterminated by greedy whalers and seal hunters. He has been at the Charles Darwin Research Station on Santa Cruz island ever since, on the off-chance that scientific ingenuity will conjure up a way of reproducing him and resurrecting his species. Meanwhile a million tourists and dozens of baffled scientists have looked on as the celebrity reptile shows not a jot of interest in the female company provided. Today, Lonesome George has come to embody the mystery, complexity and fragility of the unique Galapagos archipelago. His story echoes the challenges of conservation worldwide; it is a story of Darwin, sexual dysfunction, adventure on the high seas, cloning, DNA fingerprinting and eco-tourism.

    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.

    But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures--real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment--a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story.
