This book is a supplement to What If? and intended to enhance the experience of reading the original book. We recommend purchasing the full version of What If? on Amazon in addition to this book. Introduction What If? Serious Scientific Answers to Absurd Hypothetical Questions presents a wide variety of questions covering a range of dubious potentialities and the results which would ensue should they become reality. The questions are collected from author Randall Munroe’s website, where they are sent in by readers of his blog. Some of the questions are conceptual, for example how much force would be required for Yoda to lift an X-fighter, others are in a more serious vein. All of the answers however are based on research and the application of scientific principles by the author, himself trained in physics and a former roboticist for NASA.

    The trilobites, which dominated the ocean floors for 300 million years, are gone. The last of the dinosaurs was wiped out by a Mount Everest-sized meteorite that slammed into the earth 65 million years ago. The great flying reptiles are gone, and so are the marine reptiles, some of them larger than a humpback whale. Before humans crossed the Bering land bridge some 15,000 years ago, North America was populated by mastodons, mammoths, saber-toothed tigers, and cave bears. They too are MIA. Passenger pigeons once flew over North America in flocks that numbered in the billions; the last one died in 1914.In this book you will meet creatures that were driven to extinction even more recently, as well as some that were brought back from the brink. You will even encounter animals not known to exist until recently -- an antidote to extinction.

    In The Missing Lynx, Ross Barnett uses case studies, new fossil discoveries, biomolecular evidence and more to paint pictures of these extinct species, and to explore the significance of the lynx's disappearance in ecological terms. He also discusses how the Britons that these animals shared their home with might have viewed them, and why some survived while others vanished.Barnett also looks in detail and the realistic potential of reintroductions and even of resurrection--topics that capture public interest today. With Beaver now wild again in various parts of Britain and even Great Bustard on Salisbury Plain, what about the return of sabretooths, mammoths, and the aurochs to modern ecosystems? Will we ever be able to bring these animals back? And should we?At a time where rewilding is moving from pie-in-the-sky to actual reality, this timely and important book looks from a scientific perspective at the magnificent megafauna we've lost, why we lost it and what happened as a result, and how we might realistically turn the ecological tide.

    A narrative masterpiece and a naturalist’s delight, The Hidden Life of Deer is based on the twelve months Thomas, a renowned anthropologist, spent studying the local deer population near her home in New Hampshire.

    Its geology, its unique flora and fauna, and its striking role in human history intersect in surprising and dynamic ways. This book is the most wide-ranging and beautifully illustrated book available on the famous islands. Not since Darwin’s Naturalist’s Voyage has a book combined so much scientific and historic information with firsthand accounts that bring the Galápagos to life.Galápagos: The Islands That Changed the World describes how tragedy and murderous pirates curtailed settlement of the islands and how the islands’ pristine nature, spectacular geology, and defining isolation inspired Darwin’s ideas about evolution. The book explores the diverse land and marine habitats that shelter Galápagos species and considers the islands’ importance today as a frontier for science and a refuge for true wilderness. The book’s extensive gazetteer provides details about endemic plants and animals as well as travel advice about visitors’ sites, diving, photography, when to go, and what to take. Vividly illustrated throughout, this guide is an indispensable reference for natural history enthusiasts, armchair travelers, and island visitors alike.

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    In 2007 bird-watching is one of the most popular pastimes, not just in America, but throughout the world, and the range of interest runs from the specialist to the beginner.In The Wisdom of Birds, Birkhead takes the reader on a journey that not only tells us about the extraordinary lives of birds - from conception and egg, through territory and song, to migration and fully fledged breeder - but also shows how, over centuries, we have overcome superstition and untested 'truths' to know what we know, and how recent some of that knowledge is.Conceived for a general audience, and illustrated throughout with more than 100 exquisitely beautiful illustrations, many of them rarely, if ever, seen before, The Wisdom of Birds is a book full of stories, knowledge and unexpected revelations.

    Lying in the eastern Pacific Ocean, straddling the equator off the west coast of South America, the Galágos is the most pristine archipelago to be found anywhere in the tropics. It is so remote, so untouched, that the act of wading ashore can make you feel like you are the first to do so. Yet the Galágos is far more than a wild paradise on earth-it is one of the most important sites in the history of science. Home to over 4,000 species native to its shores, around 40 percent of them endemic, the islands have often been called a "laboratory of evolution." The finches collected on the Galágos inspired Darwin's revolutionary theory of natural selection. In The Galágos, science writer Henry Nicholls offers a lively natural and human history of the archipelago, charting its course from deserted wilderness to biological testing ground and global ecotourism hot spot. Describing the island chain's fiery geological origins as well as our species' long history of interaction with the islands, he draws vivid portraits of the life forms found in the Galágos, capturing its awe-inspiring landscapes, understated flora, and stunning wildlife. Nicholls also reveals the immense challenges facing the islands, which must continually balance conservation and ever encroaching development. Beautifully weaving together natural history, evolutionary theory, and his own experience on the islands, Nicholls shows that the story of the Galágos is not merely an isolated concern, but reflects the future of our species' relationship with nature-and the fate of our planet.

    Rich illustrations, systematic resumes, and extensive citations make it a valuable references source.

    However much we may think we have evolved from our animal ancestors, Desmond Morris shows that our instinct and behavior are still rooted in our animal past. 140 full-color and 10 black-and-white photographs.

    However, for naturalist and scientist Nick Davies, the call is an invitation to solve an enduring puzzle: how does the cuckoo get away with laying its eggs in the nests of other birds and tricking them into raising young cuckoos rather than their own offspring?Early observers who noticed a little warbler feeding a monstrously large cuckoo chick concluded the cuckoo's lack of parental care was the result of faulty design by the Creator, and that the hosts chose to help the poor cuckoo. These quaint views of bad design and benevolence were banished after Charles Darwin proposed that the cuckoo tricks the hosts in an evolutionary battle, where hosts evolve better defenses against cuckoos and cuckoos, in turn, evolve better trickery to outwit the hosts.For the last three decades, Davies has employed observation and field experiments to unravel the details of this evolutionary "arms race" between cuckoos and their hosts. Like a detective, Davies and his colleagues studied adult cuckoo behavior, cuckoo egg markings, and cuckoo chick begging calls to discover exactly how cuckoos trick their hosts. For birding and evolution aficionados, Cuckoo is a lyrical and scientifically satisfying exploration of one of nature's most astonishing and beautiful adaptations.

    Scientists have discovered that the way cats and dogs lap up liquids can be explained by the laws of surface tension, how ants navigate is due to polarized light, and why pistol shrimps can generate enough force to destroy aquarium glass using their ”elbows”!Each of FURRY LOGIC's six chapters tackles a separate branch of physics and, through more than 30 animal case studies, examines each creature's key features before describing the ways physics is at play in its life, how the connection between physics and animal behavior was discovered, and what remains to be found out. Science journalists Matin Durrani and Liz Kalaugher make the incredible interdisciplinary world of animals accessible to all, in an enthralling and entertaining read.

    Evolution, and Sir David Attenborough's 23-year sequence of books and BBC television 'Life' films, have culminated in the mammals and the explosion of awareness and intelligence. In the very short period of 100 million years - a mere blink in evolutionary time - the first mammals have arrived at world dominance.This came largely from hair and milk. Insulation and central heating made them adaptable to any surroundings. Care of the young led to learning and bigger brains. Otters, camels, lions, foxes and sheep, moles underground, whales at sea, bats in the air, polar bears, antelope, squirrels, mice, monkeys and man have exploited every habitat and every food source - the basis of this new narrative.David Attenborough has also evolved. In his 50 years of planning, writing and making television programmes of the first quality, he has constantly deepened his and our understanding of life on earth. This new book and its accompanying series of remarkable films in many ways crown his work. Vision, enthusiasm and the ability to share knowledge in an enthralling way - the gifts of an outstanding teacher.

    Random genetic mutation, long believed to be the main source of variation, is only a marginal factor. As the authors demonstrate in this book, the more important source of speciation, by far, is the acquisition of new genomes by symbiotic merger. The result of thirty years of delving into a vast, mostly arcane literature, this is the first book to go beyond -- and reveal the severe limitations of -- the "Modern Synthesis" that has dominated evolutionary biology for almost three generations. Lynn Margulis, whom E. O. Wilson called "one of the most successful synthetic thinkers in modern biology," and her co-author Dorion Sagan have written a comprehensive and scientifically supported presentation of a theory that directly challenges the assumptions we hold about the variety of the living world.
