This thorough revision provides a survey by groups, emphasizing adaptive morphology and physiology, while covering anatomical ground plans and basic developmental patterns. New co-author Richard Fox brings to the revision his expertise as an ecologist, offering a good balance to Ruppert's background as a functional morphologist. Rich illustrations and extensive citations make the book extremely valuable as a teaching tool and reference source.

    Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe--descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished. Ever since the first Neanderthal bones were identified in 1856, scientists have been vexed by the question, why did modern humans survive while their evolutionary cousins went extinct?The Invaders musters compelling evidence to show that the major factor in the Neanderthals' demise was direct competition with newly arriving humans. Drawing on insights from the field of invasion biology, which predicts that the species ecologically closest to the invasive predator will face the greatest competition, Pat Shipman traces the devastating impact of a growing human population: reduction of Neanderthals' geographic range, isolation into small groups, and loss of genetic diversity.But modern humans were not the only invaders who competed with Neanderthals for big game. Shipman reveals fascinating confirmation of humans' partnership with the first domesticated wolf-dogs soon after Neanderthals first began to disappear. This alliance between two predator species, she hypothesizes, made possible an unprecedented degree of success in hunting large Ice Age mammals--a distinct and ultimately decisive advantage for humans over Neanderthals at a time when climate change made both groups vulnerable.

    A seven-million-year journey to the very origins of the human lineage, First Steps shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities, our thirst for exploration, our use of language–and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. First Steps examines how walking upright helped us rise above all over species on this planet.First Steps includes an eight-page color photo insert.

    The year 2000 is alternatively the year 2544 (Buddhist), 6236 (Ancient Egyptian), 5761 (Jewish) or simply the Year of the Dragon (Chinese). The story of the creation of the Western calendar, which is related in this book, is a story of emperors and popes, mathematicians and monks, and the growth of scientific calculation to the point where, bizarrely, our measurement of time by atomic pulses is now more accurate than time itself: the Earth is an elderly lady and slightly eccentric - she loses half a second a century. Days have been invented (Julius Caesar needed an extra 80 days in 46BC), lost (Pope Gregory XIII ditched ten days in 1582) and moved (because Julius Caesar had 31 in his month, Augustus determined that he should have the same, so he pinched one from February).

    The first small cities formed not only the cradle of civilization, but the spawning ground for the earliest viral epidemics, the first opportunity for viruses to find a home in the human herd. This is a story of fear and ignorance, as everything from demons and the wrath of the gods to minority groups have been blamed for epidemics from smallpox to yellow fever to AIDS. It is a story of grief and heartbreak, as hundreds of thousands, sometimes millions, are wiped out in a single year. And it is a story of great bravery and sacrifice, as doctors and nurses put themselves in harm's way to combat yellow fever in Memphis and Ebola in Zaire, and as researchers risk their own lives to test theories of vaccines and the transmission of disease. Now, in Viruses, Plagues, and History, Michael B. A. Oldstone tells all these stories as he illuminates the history of the devastating diseases that have tormented humanity.Oldstone focuses his tale on a few of the most famous viruses humanity has battled, beginning with some we have effectively defeated, such as smallpox, polio, and measles. Nearly 300 million people were killed by smallpox in this century alone -- more than were killed in all the wars of the twentieth century combined. The author presents a vivid account of the long campaign against the virus, the insightful work of Edward Jenner, who created the smallpox vaccine from cowpox virus in 1796, and the monumental efforts of D. A. Henderson and an army of W.H.O. health care workers to finally eradicate smallpox. The smallpox virus remains the only organism that we have deliberately pushed to complete extinction in the wild.Oldstone then describes the fascinating viruses that have captured headlines in more recent years: Ebola and other hemorrhagic fevers, which literally turn their victims' organs to a bloody pulp; the Hantavirus outbreaks in the southwestern United States and elsewhere; mad cow disease, a frightening illness made worse by government mishandling and secrecy; and, of course, AIDS, often called the plague of our time. And he tells us of the many scientists watching and waiting even now for the next great plague, monitoring influenza strains to see whether the deadly variant from 1918 -- a viral strain that killed over 20 million people in 1918-1919, more than twice the military and civilian casualties of the First World War -- will make a comeback.Viruses have enormous power. They have wiped out cities, brought down dynasties, and helped destroy civilizations. But, as Michael Oldstone reveals, scientific research has given us the power to tame many of these viruses as well. Viruses, Plagues, and History shows us the panorama of humanity's long-standing conflict with our unseen viral enemies, from our successes to our continuing struggles. Oldstone's book is a vivid history of a fascinating field, and a highly reliable dispatch from a worker on the frontiers of this ongoing campaign.

    He argues that humans have evolved a universal moral instinct, unconsciously propelling us to deliver judgments of right and wrong independent of gender, education, and religion. Experience tunes up our moral actions, guiding what we do as opposed to how we deliver our moral verdicts.For hundreds of years, scholars have argued that moral judgments arise from rational and voluntary deliberations about what ought to be. The common belief today is that we reach moral decisions by consciously reasoning from principled explanations of what society determines is right or wrong. This perspective has generated the further belief that our moral psychology is founded entirely on experience and education, developing slowly and subject to considerable variation across cultures. In his groundbreaking book, Hauser shows that this dominant view is illusory.Combining his own cutting-edge research with findings in cognitive psychology, linguistics, neuroscience, evolutionary biology, economics, and anthropology, he examines the implications of his theory for issues of bioethics, religion, law, and our everyday lives.

    In Darwin Comes to Town, evolutionary biologist Menno Schilthuizen shows that evolution can in fact happen extremely quickly, and in the strangest of places: the heart of the city.Menno Schilthuizen is one of a growing number of “urban ecologists” studying how our manmade environments are accelerating the evolution of the animals and plants around us. Cities are extreme environments and, in a world of adapt or die, the wildlife sharing these spaces with us is being forced to adopt fascinating new ways of surviving, and often thriving.--Carrion crows in the Japanese city of Sendai have learned to use passing traffic to crack nuts.--Spiders in Vienna are adapting to build their webs near moth-attracting streetlights, while moths in some cities are developing a resistance to the lure of light bulbs.--Certain Puerto Rican city lizards are evolving feet that better grip surfaces like concrete.--Europe’s urban blackbirds sing at a higher pitch than their rural cousins, to be heard over the din of traffic, while many pigeons have eschewed traveling “as the crow flies” in favor of following manmade roads.Darwin Comes to Town draws on these and other eye-popping examples to share a stunning vision of urban evolution in which humans and wildlife co-exist in a unique harmony. It reveals that evolution can happen far more rapidly than Darwin dreamed, while providing a glimmer of hope that our race toward overpopulation might not take the rest of nature down with us.

    He is directly responsible for discoveries that have forced the scientific community to recast its thinking about the nature of the mind and the origins of language. He is Kanzi, an extraordinary bonobo chimpanzee who has overturned the idea that symbolic language is unique to our species. This is the moving story of how Kanzi learned to converse with humans and the profound lessons he has taught us about our animal cousins, and ourselves.". . .

    In 1966, simple Darwinism, which holds that evolution functions primarily at the level of the individual organism, was threatened by opposing concepts such as group selection, a popular idea stating that evolution acts to select entire species rather than individuals. George Williams's famous argument in favor of the Darwinists struck a powerful blow to those in opposing camps. His Adaptation and Natural Selection, now a classic of science literature, is a thorough and convincing essay in defense of Darwinism; its suggestions for developing effective principles for dealing with the evolution debate and its relevance to many fields outside biology ensure the timelessness of this critical work.

    For among the finches of Daphne Major, natural selection is neither rare nor slow: it is taking place by the hour, and we can watch.In this dramatic story of groundbreaking scientific research, Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself. The Beak of the Finch is an elegantly written and compelling masterpiece of theory and explication in the tradition of Stephen Jay Gould.With a new preface.

    How did the table fork acquire a fourth tine?  What advantage does the Phillips-head screw have over its single-grooved predecessor? Why does the paper clip look the way it does? What makes Scotch tape Scotch?   In this delightful book Henry Petroski takes a microscopic look at artifacts that most of us count on but rarely contemplate, including such icons of the everyday as pins, Post-its, and fast-food "clamshell" containers.  At the same time, he offers a convincing new theory of technological innovation as a response to the perceived failures of existing products—suggesting that irritation, and not necessity, is the mother of invention.

    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.

    Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history--and our part in it--is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Inspired by a passion for the lost Pleistocene giants, some scientists advocate bringing elephants and cheetahs to the Great Plains as stand-ins for their extinct native brethren. By reintroducing big browsers and carnivores to North America, they argue, we could rescue some of the planet's most endangered animals while restoring healthy prairie ecosystems. Critics, including biologists enmeshed in the struggle to restore native species like the gray wolf and the bison, see the proposal as a dangerous distraction from more realistic and legitimate conservation efforts. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.

    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.

    It was five feet long, with steel-blue scales, luminescent eyes and remarkable limb-like fins, unlike those of any fish she had ever seen. Determined to preserve her unusual find, she searched for days for a way to save it, but ended up with only the skin and a few bones.A charismatic amateur ichthyologist, J.L.B. Smith, saw a thumbnail sketch of the fish and was thunderstruck. He recognized it as a coelacanth (pronounced see-la-kanth), a creature known from fossils dating back 400 million years and thought to have died out with the dinosaurs. With its extraordinary limbs, the coelacanth was believed to be the first fish to crawl from the sea and evolve into reptiles, mammals and eventually mankind. The discovery was immediately dubbed the "greatest scientific find of the century." Smith devoted his life to the search for a complete specimen, afourteen-year odyssey that culminated in a dramatic act of international piracy. As the fame of the coelacanth spread, so did rumors and obsessions. Nations fought over it, multimillion-dollar expeditions were launched, and submarines hand-built to find it. In 1998, the rumors and the truth came together in a gripping climax, which brought the coelacanth back into the international limelight.A Fish Caught in Time is the entrancing story of the most rare and precious fish in the world--our own great uncle forty million times removed.
