Stephen Hawking’s phenomenal, multimillion-copy bestseller, A Brief History of Time, introduced the ideas of this brilliant theoretical physicist to readers all over the world.Now, in a major publishing event, Hawking returns with a lavishly illustrated sequel that unravels the mysteries of the major breakthroughs that have occurred in the years since the release of his acclaimed first book.

    Spanning evolutionary science from its inception to its latest findings, from discoveries and data to philosophy and history, this book is an authoritative introduction to evolutionary biology.

    

    In the past, discoveries often had to wait for the rise of the next generation to see questions in a new light and let go of old truisms. Today, in a world that is defined by a rapid rate of change, staying on the cutting edge has as much to do with shedding outdated notions as adopting new ones. In this spirit, John Brockman, publisher of the online salon Edge.org ("the world's smartest website"—The Guardian), asked 175 of the world's most influential scientists, economists, artists, and philosophers: What scientific idea is ready for retirement?Jared Diamond explores the diverse ways that new ideas emerge * Nassim Nicholas Taleb takes down the standard deviation * Richard Thaler and novelist Ian McEwan reveal the usefulness of "bad" ideas * Steven Pinker dismantles the working theory of human behavior * Richard Dawkins renounces essentialism * Sherry Turkle reevaluates our expectations of artificial intelligence * Physicist Andrei Linde suggests that our universe and its laws may not be as unique as we think * Martin Rees explains why scientific understanding is a limitless goal * Alan Guth rethinks the origins of the universe * Sam Harris argues that our definition of science is too narrow * Nobel Prize winner Frank Wilczek disputes the division between mind and matter * Lawrence Krauss challenges the notion that the laws of physics were preordained * plus contributions from Daniel Goleman, Mihaly Csikszentmihalyi, Nicholas Carr, Rebecca Newberger Goldstein, Matt Ridley, Stewart Brand, Sean Carroll, Daniel C. Dennett, Helen Fisher, Douglas Rushkoff, Lee Smolin, Kevin Kelly, Freeman Dyson, and others.

    Shubin describes how over the last half-century, scientists have been able to explore how genetic recipes build bodies during embryological development--how these inventions and adaptations occur in a nonprogressive manner in different contexts, at different speeds. Paleontology has been transformed over the last 50 years by tools and techniques of molecular biology--and it is that revolution in our understanding of the evolution of life that Shubin traces here. Each of us is a mosaic of precursors that came about at different times and places, with deep rooted connections across species that Darwin, for all he understood, could never even have imagined.

    QED--the edited version of four lectures on quantum electrodynamics that Feynman gave to the general public at UCLA as part of the Alix G. Mautner Memorial Lecture series--is perhaps the best example of his ability to communicate both the substance and the spirit of science to the layperson.The focus, as the title suggests, is quantum electrodynamics (QED), the part of the quantum theory of fields that describes the interactions of the quanta of the electromagnetic field-light, X rays, gamma rays--with matter and those of charged particles with one another. By extending the formalism developed by Dirac in 1933, which related quantum and classical descriptions of the motion of particles, Feynman revolutionized the quantum mechanical understanding of the nature of particles and waves. And, by incorporating his own readily visualizable formulation of quantum mechanics, Feynman created a diagrammatic version of QED that made calculations much simpler and also provided visual insights into the mechanisms of quantum electrodynamic processes.In this book, using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman successfully provides a definitive introduction to QED for a lay readership without any distortion of the basic science. Characterized by Feynman's famously original clarity and humor, this popular book on QED has not been equaled since its publication.

    After all, we ourselves are the product of evolution, and we can tackle many of our gravest challenges –– from lethal resurgence of antiobiotic–resistant diseases to the wave of extinctions that looms before us –– with a sound understanding of the science.

    Two scientists explore the potential of a revolutionary genetics technology capable of easily and affordably manipulating DNA in human embryos to prevent specific diseases, addressing key concerns about related ethical and societal repercussions.

    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?

    The material is arranged chronologically beginning with archaic origins and covers Egyptian, Mesopotamian, Greek, Chinese, Indian, Arabic and European contributions done to the nineteenth century and present day. There are revised references and bibliographies and revised and expanded chapters on the nineteeth and twentieth centuries.

    Yet there’s a black hole at the heart of biology. We do not know why complex life is the way it is, or, for that matter, how life first began. In The Vital Question, award-winning author and biochemist Nick Lane radically reframes evolutionary history, putting forward a solution to conundrums that have puzzled generations of scientists.For two and a half billion years, from the very origins of life, single-celled organisms such as bacteria evolved without changing their basic form. Then, on just one occasion in four billion years, they made the jump to complexity. All complex life, from mushrooms to man, shares puzzling features, such as sex, which are unknown in bacteria. How and why did this radical transformation happen?The answer, Lane argues, lies in energy: all life on Earth lives off a voltage with the strength of a lightning bolt. Building on the pillars of evolutionary theory, Lane’s hypothesis draws on cutting-edge research into the link between energy and cell biology, in order to deliver a compelling account of evolution from the very origins of life to the emergence of multicellular organisms, while offering deep insights into our own lives and deaths.Both rigorous and enchanting, The Vital Question provides a solution to life’s vital question: why are we as we are, and indeed, why are we here at all?

    Back in the 1990s--working undercover with his colleagues in the environmental movement--he would descend on trial sites of genetically modified crops at night and hack them to pieces. Two decades later, most people around the world--from New York to China--still think that 'GMO' foods are bad for their health or likely to damage the environment. But Mark has changed his mind. This book explains why.In 2013, in a world-famous recantation speech, Mark apologised for having destroyed GM crops. He spent the subsequent years touring Africa and Asia, and working with plant scientists who are using this technology to help smallholder farmers in developing countries cope better with pests, diseases and droughts.This book lifts the lid on the anti-GMO craze and shows how science was left by the wayside as a wave of public hysteria swept the world. Mark takes us back to the origins of the technology and introduces the scientific pioneers who invented it. He explains what led him to question his earlier assumptions about GM food, and talks to both sides of this fractious debate to see what still motivates worldwide opposition today. In the process he asks--and answers--the killer question: how did we all get it so wrong on GMOs?

    She is perhaps the best known and most studied fossil hominid of the twentieth century, the benchmark by which other discoveries of human ancestors are judged.”–From Lucy’s LegacyIn his New York Times bestseller, Lucy: The Beginnings of Humankind, renowned paleoanthropologist Donald Johanson told the incredible story of his discovery of a partial female skeleton that revolutionized the study of human origins. Lucy literally changed our understanding of our world and who we come from. Since that dramatic find in 1974, there has been heated debate and–most important–more groundbreaking discoveries that have further transformed our understanding of when and how humans evolved. In Lucy’s Legacy, Johanson takes readers on a fascinating tour of the last three decades of study–the most exciting period of paleoanthropologic investigation thus far. In that time, Johanson and his colleagues have uncovered a total of 363 specimens of Australopithecus afarensis (Lucy’s species, a transitional creature between apes and humans), spanning 400,000 years. As a result, we now have a unique fossil record of one branch of our family tree–that family being humanity–a tree that is believed to date back a staggering 7 million years.Focusing on dramatic new fossil finds and breakthrough advances in DNA research, Johanson provides the latest answers that post-Lucy paleoanthropologists are finding to questions such as: How did Homo sapiens evolve? When and where did our species originate? What separates hominids from the apes? What was the nature of Neandertal and modern human encounters? What mysteries about human evolution remain to be solved?Donald Johanson is a passionate guide on an extraordinary journey from the ancient landscape of Hadar, Ethiopia–where Lucy was unearthed and where many other exciting fossil discoveries have since been made–to a seaside cave in South Africa that once sheltered early members of our own species, and many other significant sites. Thirty-five years after Lucy, Johanson continues to enthusiastically probe the origins of our species and what it means to be human.

    Today we can see a recreation of the making of the Laetoli footprints at the American Museum of Natural History, in a stunning diorama which depicts two of our human forebears walking side by side through a snowy landscape of volcanic ash. But how do we know what these three-million-year-old relatives looked like? How have we reconstructed the eons-long journey from our first ancient steps to where we stand today? In short, how do we know what we think we know about human evolution? In The Fossil Trail, Ian Tattersall, the head of the Anthropology Department at the American Museum of Natural History, takes us on a sweeping tour of the study of human evolution, offering a colorful history of fossil discoveries and a revealing insider's look at how these finds have been interpreted--and misinterpreted--through time. All the major figures and discoveries are here. We meet Lamarck and Cuvier and Darwin (we learn that Darwin's theory of evolution, though a bombshell, was very congenial to a Victorian ethos of progress), right up to modern theorists such as Niles Eldredge and Stephen Jay Gould. Tattersall describes Dubois's work in Java, the many discoveries in South Africa by pioneers such as Raymond Dart and Robert Broom, Louis and Mary Leakey's work at Olduvai Gorge, Don Johanson's famous discovery of Lucy (a 3.4 million-year-old female hominid, some 40% complete), and the more recent discovery of the Turkana Boy, even more complete than Lucy, and remarkably similar to modern human skeletons. He discusses the many techniques available to analyze finds, from fluorine analysis (developed in the 1950s, it exposed Piltdown as a hoax) and radiocarbon dating to such modern techniques as electron spin resonance and the analysis of human mitochondrial DNA. He gives us a succinct picture of what we presently think our family tree looks like, with at least three genera and perhaps a dozen species through time (though he warns that this greatly underestimates the actual diversity of hominids over the past two million or so years). And he paints a vivid, insider's portrait of paleoanthropology, the dogged work in the broiling sun, searching for a tooth, or a fractured corner of bone, amid stone litter and shadows, with no guarantee of ever finding anything. And perhaps most important, Tattersall looks at all these great researchers and discoveries within the context of their social and scientific milleu, to reveal the insidious ways that the received wisdom can shape how we interpret fossil findings, that what we expect to find colors our understanding of what we do find. Refreshingly opinionated and vividly narrated, The Fossil Trail is the only book available to general readers that offers a full history of our study of human evolution. A fascinating story with intriguing turns along the way, this well-illustrated volume is essential reading for anyone curious about our human origins.
