The Big Questions series is designed to let renowned experts address the 20 most fundamental and frequently asked questions of a major branch of science or philosophy. Each 3,000-word essay simply and concisely examines a question that has eternally perplexed enquiring minds, and provides answers based on the latest research. This ambitious project is a unique distillation of humanity's best ideas. In "The Big Questions: Evolution," Francisco Ayala answers the 20 key questions: What is evolution? Was Darwin right? What is natural selection? What is survival of the fittest? Is evolution a random process? What is a species? What are chromosomes, genes and DNA? How do genes build bodies? What is molecular evolution? How did life begin? What is the tree of life? Am I really a monkey? What does the fossil record tell us? What is the missing link? Is intelligence inherited? Will humans continue to evolve? Can I clone myself? Where does morality come from? Is language a uniquely human attribute? Is Creationism true?

    She had no intention of staying long; she simply wanted to see if the rumors were true. That initial trip changed Smolker’s life; it commenced a fifteen-year scientific obsession that has culminated in this fascinating scientific adventure story–the first-ever intimate account of dolphin life in the wild.To Touch A Wild Dolphin is a seminal work that radically alters our fundamental understanding of these enigmatic creatures. Learning to identify scores of dolphins by their dorsal fin, Smolker and her team of scientists were able to conduct close and consistent studies that revealed the dolphin to be even more intelligent than we’d previously suspected. And while they were every bit as playful as we’ve known them to be, they also proved to have a dark and alarmingly violent side. But more than just a document on dolphins, this book is a touchingly personal look at the life of a scientist, at the rigors and sacrifices but also the wonders and joys of unending days in the field. Written with prose poetic and pristine, this book is nothing short of a landmark.

    Eighty-seven at the time of writing and an internationally renowned figure, he vividly describes expeditions to almost every part of the subcontinent, including the old Princely States, Burma, Sikkim, Tibet, Bhutan and Afghanistan. As he tells of his life as motorcyclist, timber merchant, scientist, author and decorated celebrity, a picture also emerges of pre-independent India, of Maharajas and colonial administration.

    Here and there, we can supplement these meager scraps by the use of biochemical markers or geochemical signatures that add useful information, but, even with such additional help, our reconstructions and our models of descent are often tentative. For the fossil record is, as we have seen, as biased as it is incomplete. But fragmentary, selective, and biased though it is, the fossil record, with all its imperfections, is still a treasure. Though whole chapters are missing, many pages lost, and the earliest pages so damaged as to be, as yet, virtually unreadable, this--the greatest biography of all--is one in whose closing pages we find ourselves.--from OriginsIn Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.Rhodes's accessible and extensively illustrated treatment of the origins narrative describes the nature of the search for prehistoric life, the significance of geologic time, the origin of life, the emergence and spread of flora and fauna, the evolution of primates, and the emergence of modern humans.

    And survival is never a given. Somehow, a blind, defenseless tiger kitten must evolve into a deadly, efficient predator; a chimp must learn to distinguish edible plants from lethal poisons; a baby buffalo must be able to pick its mother out of a herd of hundreds. Contrary to common belief, not everything is "hardwired" -- or instinctual -- in the animal kingdom. Many skills a wild animal needs to thrive, to grow, to be what nature intended, must be developed through play, painstaking teaching, and often treacherous trial and error. The coming-of-age processes of the myriad creatures of plain, forest, ocean, and jungle are truly fascinating and often astonishing natural events.In Becoming a Tiger, Susan McCarthy, co-author of the critically acclaimed New York Times bestseller When Elephants Weep, offers readers an in-depth look into the amazing ways baby animals learn not only about themselves, but about their world and ours -- and how to survive in both. Based on extensive scientific research done in the lab, in controlled "natural" settings, as well as in the wild, her findings provide stunning new insights into the lives and development of Earth's nonhuman inhabitants -- not only tigers, but lions, bears, bats, rats, birds, dolphins, whales, apes, elephants, and dozens of other species.Sharing stories and discoveries at once captivating, funny, breathtaking, provocative, and heartwarming, Susan McCarthy carries us on a remarkable journey into untamed places, immersing us in the fascinating, complex, and hitherto unimagined societies and cultures of the beasts and birds. Along the way she shines a brilliant new light on subjects scientists, biologists, and zoologists have only begun to explore, revealing startling truths about the behavior, and sometimes humanlike foibles, of creatures great and small.Warm, informative, and beautifully written, Becoming a Tiger is an enthralling reading experience for animal lovers everywhere. In the transformation tales of playful pups, big-footed cubs, and scrawny chicks becoming deadly hunters, able foragers, and deft nest-builders are valuable and enriching life lessons for members of our own inquisitive, ever-developing species.

    We find animals and plants where we do because, over time, the continents have moved, separating and uniting in a long, slow dance; because sea levels have risen, cutting off one bit of land from another; because new and barren volcanic islands have risen up from the sea; and because animals and plants vary greatly in their ability to travel, and separation causes the formation of new species. This is the story of how life has responded to, and has in turn altered, the ever-changing Earth. And it includes many fascinating tales--of pygmy mammoths and elephant birds and of radical ideas by bold young scientists.

    This shy, snuffling, enigmatic animal has captured the imagination of children and adults for centuries – from Beatrix Potter’s Mrs Tiggywinkle to Sonic the Hedgehog.Full to the brim with fascinating insights and countryside lore, The Hedgehog Handbook explores different facets of this much-admired mammal – from its wildlife habits to its literary heritage, how different cultures have viewed the hedgehog and what we can do to help preserve this icon of rural life. Fun, sweet and warm hearted, The Hedgehog Handbook is a month by month celebration of one of the countryside’s best-loved creatures. Packed with inspirational quotes, entertaining facts, folklore and literary references, it’s the perfect gift for anyone with a penchant for prickles.

    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

    It develops an understanding of function and evolution into the discussion of anatomy of the various systems.

    He spent two years gathering information that demonstrates this and along the way interviewed more than a hundred experts in a number of different fields. Among them were parapsychologists, medical doctors, psychologists, psychiatrists, quantum physicists, and researchers into the true nature of reality. Specific examples are presented that indicate what happens when we die, for example that memories can be formed and retained despite a subject’s brain having been shutdown and the blood drained from it. Questions such as whether or not you will be able to communicate with living loved ones after death are addressed, if it is possible to be reborn, and what might be missing from reproductive theory to explain the various phenomena indicated in the many case histories and scientific investigations presented. All of us will someday cross the border to what Shakespeare called "The undiscovered country." As long as we must make that trip, wouldn’t it be smart to find out where we are going and what to expect when we get there?

    Do animals survive the death of the body, or are they doomed to disappear completely when they leave this world behind? Both scientists and religious authorities have long scoffed at the idea of animals in heaven. Yet the question endures. In this wise, immensely readable book, Ptolemy Tompkins embarks on a quest for the answer—taking us on a top-speed tour of the history of the animal soul. Equally at home with mainstream and alternative spiritual philosophies, Tompkins takes us from the savannas of Africa to the earth’s first cities to the early days of the great faith traditions of both East and West. Along the way, he shows that, despite what many of us have been taught, the world’s various spiritual traditions all have profoundly meaningful things to say about the animal soul, if we simply know where to look. Rescuing these ancient insights and blending them with vivid stories about animals today—from a dwarf rabbit named Angus to a manatee named Moose to a black bear named Little Bit—The Divine Life of Animals paints a gloriously inclusive picture of the cosmos as a place made up of both matter and spirit, in which animals are every bit as important, spiritually speaking, as the humans with whom they share the world. Though it is startlingly original, The Divine Life of Animals also feels strangely and instantly familiar, for it reveals truths that many of us have held in our hearts already, waiting only for someone to give fresh voice to one of the oldest and most trustworthy intuitions we possess.  The Divine Life of Animals offers a compelling and timeless vision of the relationship between humans and animals that will have you looking at the animals in your life with new eyes.From the Hardcover edition.

    Unlike Origin, this book focuses on human ancestry and offers a concise, nontechnical survey of the state of mid-nineteenth-century knowledge about primate and human paleontology and ethology.Man's Place in Nature concurs with Darwin's assertion of the absence of a physiologic and psychic structural line of demarcation between humans and apes. Huxley ventures further than Darwin, however, by making the first attempt to apply the principles of evolution directly to the human race (an issue that Darwin skirted). Despite Huxley's acknowledgements of the wide gulf represented by the human capacity for rational speech and language, some Victorian readers were scandalized by the application of Darwinian theory to humans and by Huxley's evidence of the fundamental similarities between the human brain and the ape brain.A landmark of scientific progress, this immensely readable book reflects the stylistic gifts that made its author a popular public speaker.

    Its presence in nature was dismissed as a desperate response to starvation or other life-threatening circumstances, and few spent time studying it. A taboo subject in our culture, the behavior was portrayed mostly through horror movies or tabloids sensationalizing the crimes of real-life flesh-eaters. But the true nature of cannibalism--the role it plays in evolution as well as human history--is even more intriguing (and more normal) than the misconceptions we've come to accept as fact. In Cannibalism: A Perfectly Natural History, zoologist Bill Schutt sets the record straight, debunking common myths and investigating our new understanding of cannibalism's role in biology, anthropology, and history in the most fascinating account yet written on this complex topic. Schutt takes readers from Arizona's Chiricahua Mountains, where he wades through ponds full of tadpoles devouring their siblings, to the Sierra Nevadas, where he joins researchers who are shedding new light on what happened to the Donner Party--the most infamous episode of cannibalism in American history. He even meets with an expert on the preparation and consumption of human placenta (and, yes, it goes well with Chianti). Bringing together the latest cutting-edge science, Schutt answers questions such as why some amphibians consume their mother's skin; why certain insects bite the heads off their partners after sex; why, up until the end of the twentieth century, Europeans regularly ate human body parts as medical curatives; and how cannibalism might be linked to the extinction of the Neanderthals. He takes us into the future as well, investigating whether, as climate change causes famine, disease, and overcrowding, we may see more outbreaks of cannibalism in many more species--including our own.Cannibalism places a perfectly natural occurrence into a vital new context and invites us to explore why it both enthralls and repels us.

    Thanks to cartoons and folk accounts we have a distorted view of these other humans - for that is what they were. We think of them as crude and clumsy and not very bright, easily driven to extinction by the lithe, smart modern humans that came out of Africa some 100,000 years ago.But was it really as simple as that? Clive Finlayson reminds us that the Neanderthals were another kind of human, and their culture was not so very different from that of our own ancestors. In this book, he presents a wider view of the events that led to the migration of the moderns into Europe, what might have happened during the contact of the two populations, and what finally drove the Neanderthals to extinction. It is a view that considers climate, ecology, and migrations of populations, as well as culture and interaction.His conclusion is that the destiny of the Neanderthals and the Moderns was sealed by ecological factors and contingencies. It was a matter of luck that we survived and spread while the Neanderthals dwindled and perished. Had the climate not changed in our favour some 50 million years ago, things would have been very different.There is much current research interest in Neanderthals, much of it driven by attempts to map some of their DNA. But it's not just a question of studying the DNA. The rise and fall of populations is profoundly moulded by the larger scale forces of climate and ecology. And it is only by taking this wider view that we can fully understand the course of events that led to our survival and their demise. The fact that Neanderthals survived until virtually yesterday makes our relationship with them and their tragedy even more poignant. They almost made it, after all.

    On the one hand wrens are ubiquitous. They are Britain's most common bird, with 8.5 million breeding pairs and have by far the loudest song in proportion to their size. They also thrive up and down Britain and Ireland: from the smallest city garden to remote offshore islands, blustery moors to chilly mountains. Yet many people, particularly a younger generation, are not sure if they have ever seen a wren. Perhaps because the wren is so tiny, weighing just as much as two A4 sheets of paper, and so busy, always on the move, more mouse than bird. However if we cast our eyes back to recent history wrens were a mainstay of literary, cultural and popular history. The wren was on postage stamps and the farthing, it featured in nursery rhymes and greetings cards, poems and rural `wren hunts', still a recent memory in Ireland particularly. With beautiful illustrations throughout, this captivating year-in-the-life biography reveals the hidden secrets of this fascinating bird that lives right on our doorstep.
