Buried there lie answers about the origins of humankind. After a century of investigation, scientists have transformed our understanding about the beginnings of human life. But vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies as well as their feats of skill and endurance.The results have been momentous. Scientists have identified more than twenty species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans. They have revealed how early technology, language ability, and artistic endeavour all originated in Africa; and they have shown how small groups of Africans spread out from Africa in an exodus sixty thousand years ago to populate the rest of the world. We have all inherited an African past.

    But there is a method for avoiding such pitfalls of human nature, and it's called skepticism. By using rational inquiry and seeing subjects from a scientific perspective, we can approach even the most sensitive claims with clear eyes to ultimately arrive at the truth. During 18 lectures that will surprise, challenge, and entertain you, you will learn how to think, not just what to think-and you'll come to understand why extraordinary claims require extraordinary evidence.You'll discover how skepticism can help differentiate between real science and pseudoscience, as well as between "scientific" history and pseudohistory-distinctions that have serious educational and political implications.Fascinating case studies illustrate how you can apply the methods of skepticism to detect specious claims and faulty logic in any scenario you encounter such as:•The methodology employed by Holocaust deniers•Arguments made by proponents of creationism•The biology of near-death experiences and the sensed-presence effect•Psychic abilities and other "paranormal" phenomena.As you learn how our brains work to form beliefs, you'll examine the classic fallacies of thought that lead us to experience mistakes in thinking and to form bad arguments in favor of our beliefs.Is there a God? Is there life after death? Is there a basis for morality without God? Skepticism 101 doesn't shy away from controversial questions, nor does it give final answers. What it offers are methods and hard evidence for rationally evaluating various claims and positions, and an opportunity to understand why you believe what you believe.Listening Length: 9 hours and 10 minutes

    Beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in the sequencing of the Neanderthal genome in 2010, Neanderthal Man describes the events, intrigues, failures, and triumphs of these scientifically rich years through the lens of the pioneer and inventor of the field of ancient DNA.We learn that Neanderthal genes offer a unique window into the lives of our hominin relatives and may hold the key to unlocking the mystery of why humans survived while Neanderthals went extinct. Drawing on genetic and fossil clues, Pääbo explores what is known about the origin of modern humans and their relationship to the Neanderthals and describes the fierce debate surrounding the nature of the two species’ interactions. His findings have not only redrawn our family tree, but recast the fundamentals of human history—the biological beginnings of fully modern Homo sapiens, the direct ancestors of all people alive today.A riveting story about a visionary researcher and the nature of scientific inquiry, Neanderthal Man offers rich insight into the fundamental question of who we are.

    Darwin was only too aware of the storm his theory of evolution would provoke but he would surely have raised an incredulous eyebrow at the controversy still raging a century and a half later. Evolution is accepted as scientific fact by all reputable scientists and indeed theologians, yet millions of people continue to question its veracity.In The Greatest Show on Earth Richard Dawkins takes on creationists, including followers of ‘Intelligent Design’ and all those who question the fact of evolution through natural selection. Like a detective arriving on the scene of a crime, he sifts through fascinating layers of scientific facts and disciplines to build a cast-iron case: from the living examples of natural selection in birds and insects; the ‘time clocks’ of trees and radioactive dating that calibrate a timescale for evolution; the fossil record and the traces of our earliest ancestors; to confirmation from molecular biology and genetics. All of this, and much more, bears witness to the truth of evolution.The Greatest Show on Earth comes at a critical time: systematic opposition to the fact of evolution is now flourishing as never before, especially in America. In Britain and elsewhere in the world, teachers witness insidious attempts to undermine the status of science in their classrooms. Richard Dawkins provides unequivocal evidence that boldly and comprehensively rebuts such nonsense. At the same time he shares with us his palpable love of the natural world and the essential role that science plays in its interpretation. Written with elegance, wit and passion, it is hard-hitting, absorbing and totally convincing.

    Alexander von Humboldt (1769 – 1859) was an intrepid explorer and the most famous scientist of his age. In North America, his name still graces four counties, thirteen towns, a river, parks, bays, lakes, and mountains. His restless life was packed with adventure and discovery, whether he was climbing the highest volcanoes in the world or racing through anthrax-infected Siberia or translating his research into bestselling publications that changed science and thinking. Among Humboldt's most revolutionary ideas was a radical vision of nature, that it is a complex and interconnected global force that does not exist for the use of humankind alone. Now Andrea Wulf brings the man and his achievements back into focus: his daring expeditions and investigation of wild environments around the world and his discoveries of similarities between climate and vegetation zones on different continents. She also discusses his prediction of human-induced climate change, his remarkable ability to fashion poetic narrative out of scientific observation, and his relationships with iconic figures such as Simón Bolívar and Thomas Jefferson. Wulf examines how Humboldt's writings inspired other naturalists and poets such as Darwin, Wordsworth, and Goethe, and she makes the compelling case that it was Humboldt's influence that led John Muir to his ideas of natural preservation and that shaped Thoreau's Walden.With this brilliantly researched and compellingly written book, Andrea Wulf shows the myriad fundamental ways in which Humboldt created our understanding of the natural world, and she champions a renewed interest in this vital and lost player in environmental history and science.

    In The Botany of Desire, Michael Pollan ingeniously demonstrates how people and domesticated plants have formed a similarly reciprocal relationship. He masterfully links four fundamental human desires—sweetness, beauty, intoxication, and control—with the plants that satisfy them: the apple, the tulip, marijuana, and the potato. In telling the stories of four familiar species, Pollan illustrates how the plants have evolved to satisfy humankind’s most basic yearnings. And just as we’ve benefited from these plants, we have also done well by them. So who is really domesticating whom?

    And, although novels and short stories built the foundations of science fiction, film and television have emerged as equally powerful, experimental, and enjoyable ways to experience the genre. Even as far back as the silent era, films like Fritz Lang’s Metropolis have used science fiction to tell stories that explore many facets of human experience.In Sci-Phi: Science Fiction as Philosophy, Professor of Philosophy David Kyle Johnson of King’s College takes you on a 24-lecture exploration of the final frontiers of philosophy across several decades of science fiction in film and television. From big-budget blockbusters to television series featuring aliens in rubber masks, Professor Johnson finds food for philosophical thought in a wide range of stories. By looking at serious questions through astonishing tales and astounding technologies, you will see how science fiction allows us to consider immense, vital—and sometimes controversial—ideas with a rare combination of engagement and critical distance.The Future Is NowScience fiction is often concerned with the future, being used not only as a tool of prediction—humans are notoriously bad at accurately predicting the future—but also as one of extrapolation and interrogation. Rather than simply asking what the future will look like, the futuristic visions of sci-fi TV, like Star Trek, Firefly, and even the animated comedy Futurama, offer compelling statements about humanity’s hopes, dreams, and fears. We can, therefore, use fictionalized futures to better understand today’s world.Setting a story in the future—or in an alternate reality, or on a faraway planet—also allows sci-fi creators to open up the realm of possibility beyond what our current world offers, while also looking at very real scientific possibilities. As you look at sci-fi films like Arrival and Interstellar, Professor Johnson highlights the kinds of issues worth considering if contact with extraterrestrial life or time travel became part of our real-life experience. And even if these experiences remain in the realm of fiction, considering them still provides insight into important philosophical questions. Indeed, throughout the lectures of Sci-Phi, you will ponder many questions that have concerned philosophers for centuries, including:Do humans truly have free will?Could machines one day be conscious? Or be sentient?Could we actually be living in a simulated world?How will humanity confront a future of diminished resources and advancing technology?Are science and religion compatible?When, if ever, is war justified?How do we know what information to trust and what to dismiss?Exploring Reality through FictionStaples of science fiction like time travel, alternate universes, and extraterrestrial life are endlessly fascinating ideas to explore. Yet, despite the insights they can give us, they may not seem very relevant to everyday life. Even our conception of reality—what is real and what isn’t—can have little bearing on the more mundane aspects of living from day to day. But science fiction, for all its futurism and outlandish flourishes, is not limited to these theoretical concepts; it is also a window into crucial discussions about the here and now, questions concerning ethics, power, religion, tolerance, social justice, politics, and the many practical dimensions of living in a world that is constantly changing and forever presenting humans with fresh new dilemmas to solve. And by removing us from reality, sci-fi can also remove our biases and make us see such issues anew.Indeed, as Professor Johnson makes clear, stories of simulated worlds and artificial intelligence can seem far-fetched, but they actually offer valuable insights into social and ethical issues that may be more immediate and relevant than they first appear. By looking at them through fiction, we can take a step back and get a clearer picture of the larger implications. For instance, by looking at characters like Commander Data in Star Trek: The Next Generation or the Cylons in Battlestar Galactica, we are forced to wonder: If we create artificial intelligence that achieves true sentience, how will we treat these man-made beings? Will we repeat the sins of the past by enslaving them or will we embrace them as our equals? If we are ever able to re-create a convincing version of the world via computers, as films like The Matrix and The Thirteenth Floor suggest, do the lives lived in those simulations mean less than those in the “real” world? The answers to these questions—and many others—speak volumes about human values and, given our ever-evolving technology, may require answers sooner rather than later.You may be surprised to see how often a science fiction story can “trick” you into thinking about questions and concepts you may have never considered. Shows like The Twilight Zone and Black Mirror overtly present questions and issues for audiences to ponder. However, while other films and television shows may seem to focus more on the adventure and entertainment value of science fiction, they still often have deep philosophical dimensions. Consider the long-running British TV series Doctor Who. A beloved icon of science fiction, the show has always been framed as simply the exciting weekly adventures of a time-traveling alien; yet, throughout its decades on television, it has explored issues of autonomy, sentience, pacifism, colonialism, racism, grief, morality, and much more.A Unique View of PhilosophyWhile each lecture of Sci-Phi focuses on a few key films or television episodes, you will also explore dozens of other movies and TV episodes along the way. Likewise, each philosophical concept you explore opens the door to further discovery. Throughout the lectures, you will be introduced to the ideas of great thinkers like Descartes, Hobbes, Locke, Marx, Nietzsche, Sartre, Turing, Baudrillard, and many others; and through these ideas, you will better understand the different ways philosophy examines the big questions, from metaphysics and epistemology to existentialism and ethics.Fans of the genre will find their experience of sci-fi stories enriched by layers of philosophical inquiry that reveal each story to be much more than just entertainment. Similarly, those who are looking for a thrilling and accessible introduction to philosophy will be equally rewarded by Professor Johnson’s breadth of knowledge, as well as his deep and abiding love for both science fiction storytelling and philosophical exploration. As you engage with philosophy by way of sci-fi stories for screens both large and small, it is important to keep in mind that Professor Johnson will not shy away from revealing key plot points in many of the stories he explores throughout the lectures; so, although it is not required, watching the films and TV episodes at the heart of each lecture is recommended. Presented as a one-on-one conversation and enlivened by fun visual references to many of the stories you will encounter, Sci-Phi: Science Fiction as Philosophy is a philosophy course unlike any other.Whether telling stories of far-flung futures or investigating the here and now, science fiction is an invaluable source of intellectual and imaginative exploration. From the genre-defining classics like Star Wars, Doctor Who, 2001: A Space Odyssey, and The Twilight Zone to a new wave of speculative tales like Transcendence, Snowpiercer, Westworld, and The Hunger Games, sci-fi stories offer a uniquely engaging and incisive way to ask serious questions about the world we live in, even when those stories are set in a galaxy far, far away. Philosophy is the search for truth. Sometimes that truth is best revealed through fiction.

    Focusing on four specific examples — corn, silkworms, domestic cats, and apples — she traces the histories of species that have been fundamentally altered over the centuries by the whims and needs of people.

    In The Violinist's Thumb, he explores the wonders of the magical building block of life: DNA.There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking. They can even allow some people, because of the exceptional flexibility of their thumbs and fingers, to become truly singular violinists. Kean's vibrant storytelling makes science entertaining, explaining human history and whimsy while showing how DNA will influence our species' future.

    Each professor addresses an area of personal expertise and focuses not only on the matter at hand, but on the larger story-on the links between the works and the figures discussed. The lectures address-in chronological sequence-a series of major works that have shaped the ongoing development of Western thought both in their own right and in cultural dialogue with other traditions. In the process, the course engages many of the most perennial and far-reaching questions that we face in our daily lives.Lecture 1 From Sumer to AthensLecture 2 The Epic of GilgameshLecture 3 The Hebrew Bible: Historical Background and GenesisLecture 4 The Hebrew Bible: Exodus and the CovenantLecture 5 The Hebrew Bible: Psalms, Prophets, The Song of Songs, and JobLecture 6 Greece: From the Bronze Age to the Archaic AgeLecture 7 The IliadLecture 8 Homer: The OdysseyLecture 9 Hesiod and Lyric PoetryLecture 10 Greek Tragedy: AeschylusLecture 11 Greek Tragedy: SophoclesLecture 12 Greek Tragedy: EuripidesLecture 13 Herodotus of HalicarnassusLecture 14 Greek Art

    But in recent decades, these claims have eroded, or even been disproven outright, by a revolution in the study of animal cognition. Take the way octopuses use coconut shells as tools; elephants that classify humans by age, gender, and language; or Ayumu, the young male chimpanzee at Kyoto University whose flash memory puts that of humans to shame. Based on research involving crows, dolphins, parrots, sheep, wasps, bats, whales, and of course chimpanzees and bonobos, Frans de Waal explores both the scope and the depth of animal intelligence. He offers a firsthand account of how science has stood traditional behaviorism on its head by revealing how smart animals really are, and how we’ve underestimated their abilities for too long.People often assume a cognitive ladder, from lower to higher forms, with our own intelligence at the top. But what if it is more like a bush, with cognition taking different forms that are often incomparable to ours? Would you presume yourself dumber than a squirrel because you’re less adept at recalling the locations of hundreds of buried acorns? Or would you judge your perception of your surroundings as more sophisticated than that of a echolocating bat? De Waal reviews the rise and fall of the mechanistic view of animals and opens our minds to the idea that animal minds are far more intricate and complex than we have assumed. De Waal’s landmark work will convince you to rethink everything you thought you knew about animal—and human—intelligence.

    . . a book that enriches our understanding of how the struggle to think new thoughts is shared across time and space and people.”—The Sunday Telegraph (London)Christmas, 1859. Just one month after the publication of On the Origin of Species, Charles Darwin received an unsettling letter. He had expected criticism; in fact, letters were arriving daily, most expressing outrage and accusations of heresy. But this letter was different. It accused him of failing to acknowledge his predecessors, of taking credit for a theory that had already been discovered by others. Darwin realized that he had made an error in omitting from Origin of Species any mention of his intellectual forebears. Yet when he tried to trace all of the natural philosophers who had laid the groundwork for his theory, he found that history had already forgotten many of them.Darwin’s Ghosts tells the story of the collective discovery of evolution, from Aristotle, walking the shores of Lesbos with his pupils, to Al-Jahiz, an Arab writer in the first century, from Leonardo da Vinci, searching for fossils in the mine shafts of the Tuscan hills, to Denis Diderot in Paris, exploring the origins of species while under the surveillance of the secret police, and the brilliant naturalists of the Jardin de Plantes, finding evidence for evolutionary change in the natural history collections stolen during the Napoleonic wars. Evolution was not discovered single-handedly, Rebecca Stott argues, contrary to what has become standard lore, but is an idea that emerged over many centuries, advanced by daring individuals across the globe who had the imagination to speculate on nature’s extraordinary ways, and who had the courage to articulate such speculations at a time when to do so was often considered heresy.With each chapter focusing on an early evolutionary thinker, Darwin’s Ghosts is a fascinating account of a diverse group of individuals who, despite the very real dangers of challenging a system in which everything was presumed to have been created perfectly by God, felt compelled to understand where we came from. Ultimately, Stott demonstrates, ideas—including evolution itself—evolve just as animals and plants do, by intermingling, toppling weaker notions, and developing over stretches of time. Darwin’s Ghosts presents a groundbreaking new theory of an idea that has changed our very understanding of who we are.

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    In this book, he expands the points he has made, and claims that this debate is not so much about religion versus science, as about the nature of science itself. With infectious enthusiasm, he reveals the mechanics of evolutionary theory, explains how it is rooted in the testable and verifiable scientific method, and why it is therefore a sound explanation of our beginning. He argues passionately that to continue to assert otherwise, to continue to insist that creationism has a place in the science classroom is harmful not only to our children, but to the future of the greater world as well.
