But, despite appearances, these are not dogs—they are foxes. They are the result of the most astonishing experiment in breeding ever undertaken—imagine speeding up thousands of years of evolution into a few decades. In 1959, biologists Dmitri Belyaev and Lyudmila Trut set out to do just that, by starting with a few dozen silver foxes from fox farms in the USSR and attempting to recreate the evolution of wolves into dogs in real time in order to witness the process of domestication. This is the extraordinary, untold story of this remarkable undertaking. Most accounts of the natural evolution of wolves place it over a span of about 15,000 years, but within a decade, Belyaev and Trut’s fox breeding experiments had resulted in puppy-like foxes with floppy ears, piebald spots, and curly tails. Along with these physical changes came genetic and behavioral changes, as well. The foxes were bred using selection criteria for tameness, and with each generation, they became increasingly interested in human companionship. Trut has been there the whole time, and has been the lead scientist on this work since Belyaev’s death in 1985, and with Lee Dugatkin, biologist and science writer, she tells the story of the adventure, science, politics, and love behind it all.  In How to Tame a Fox, Dugatkin and Trut take us inside this path-breaking experiment in the midst of the brutal winters of Siberia to reveal how scientific history is made and continues to be made today. To date, fifty-six generations of foxes have been domesticated, and we continue to learn significant lessons from them about the genetic and behavioral evolution of domesticated animals. How to Tame a Fox offers an incredible tale of scientists at work, while also celebrating the deep attachments that have brought humans and animals together throughout time.

    In all the annals of the ancient world, few stories are more gripping than those from this era.In the opening lectures, you'll explore the enigma of Alexander, son of a brilliant father, yet always at odds with the man whom he succeeded. You'll trace his early campaigns against the Persians and follow him to Egypt, where he was acclaimed as the son of god. You'll then look at his career after this and find in him a blend of greatness and madness as he strove to replace the Persian empire of the Achaemenid dynasty with a new, mixed ruling class of Macedonians and Persians.From there, you'll delve into the catastrophic period after Alexander's death in 323 B.C., which ushered in a period of catastrophic change as ambitious warlords carved up Alexander's realm into their own separate empires. You'll learn about each of the three kingdoms that resulted: Ptolemaic Egypt, Seleucid Syria, and the Attalid Empire in Asia Minor. Just as important to these lectures are the in-depth discussions of the bounties of Hellenistic culture, which contributed landmark ideas in everything from philosophy (which became more academic), art and architecture (with its excessive, naked emotions), and religion (especially the growing popularity of cult movements). Taken all together, these lectures are an engrossing and riveting journey into ancient history-and the life and times of the man who left an indelible mark on everything that would come after.

    Mainstream science--as well as religious and cultural institutions--has maintained that men and women evolved in families in which a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married, and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages.How can reality be reconciled with the accepted narrative? It can't be, according to renegade thinkers Christopher Ryan and Cacilda Jethá. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book.Ryan and Jethá's central contention is that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together convergent, frequently overlooked evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors show how far from human nature monogamy really is. Human beings everywhere and in every era have confronted the same familiar, intimate situations in surprisingly different ways. The authors expose the ancient roots of human sexuality while pointing toward a more optimistic future illuminated by our innate capacities for love, cooperation, and generosity.With intelligence, humor, and wonder, Ryan and Jethá show how our promiscuous past haunts our struggles over monogamy, sexual orientation, and family dynamics. They explore why long-term fidelity can be so difficult for so many; why sexual passion tends to fade even as love deepens; why many middle-aged men risk everything for transient affairs with younger women; why homosexuality persists in the face of standard evolutionary logic; and what the human body reveals about the prehistoric origins of modern sexuality.In the tradition of the best historical and scientific writing, Sex at Dawn unapologetically upends unwarranted assumptions and unfounded conclusions while offering a revolutionary understanding of why we live and love as we do.

    In the seventy thousand years that modern human beings have walked this earth, we've come a long way. Art, science, culture, trade - on the evolutionary food chain, we're real winners. But, frankly, it's not exactly been plain sailing, and sometimes - just occasionally - we've managed to really, truly, quite unbelievably f*ck things up.From Chairman Mao's Four Pests Campaign, to the American Dustbowl; from the Austrian army attacking itself one drunken night, to the world's leading superpower electing a reality TV mogul as President... it's pretty safe to say that, as a species, we haven't exactly grown wiser with age. So, next time you think you've really f*cked up, this book will remind you: it could be so much worse

    These 24 thought-provoking lectures offer you the chance to reflect on some of the most powerful moral issues we face in our daily lives: Is it ever OK to lie? What are our moral obligations to others? What is the key to living the good life? From Plato to Kant to Bonhoeffer, you'll see how some of the world's greatest thinkers from across the ages have approached similar problems. Professor Martin provides a complete picture of various ethical schools and approaches and applies this rich philosophical overview to "case studies" relevant to our contemporary lives. You'll explore all the ins and outs of issues such as business ethics, love and marriage, privacy and technology, genetic engineering, animal rights, and much more. Engaging stories and thought experiments bring these issues to life, showing what different philosophical theories have to say about real-world ethical dilemmas. According to Professor Martin, the trick is to understand that the mind is like a parachute; it only works when it's open. Rather than take a side in any particular debate, this course provides a framework for thinking through a host of debates and dilemmas from all sides. Through it all, Professor Martin is a sympathetic guide, helping you think through some of our most complex decisions.

    From the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day, nothing so pervades our existence and yet is so difficult to explain. Time seems to be woven into the very fabric of the universe. But why? Consider these contrasting views of time: A movie of a person diving into a pool has an obvious arrow of time. When the movie is played backward, everyone recognizes that it shows an event that would never occur in the real world. But zoom in on any part of this scene at the atomic scale and the movie can be run backward or forward and be indistinguishable. Either way, the particle interactions are consistent with the laws of physics. Why does one movie have an arrow of time moving in only one direction and the other does not? Surprisingly, the search for an answer leads through some of the most pioneering fields of physics, including thermodynamics, relativity, quantum theory, and cosmology. The key concept is called "entropy," which is related to the second law of thermodynamics, considered by many scientists to be the most secure law in all of physics. But that's only the beginning, since the quest for the ultimate theory of time draws on such exciting ideas as black holes, cosmic inflation, and dark energy, before closing in on a momentous question that until recently was considered unanswerable: What happened before the big bang? In 24 riveting half-hour lectures, Mysteries of Modern Physics: Time takes you on a mind-expanding journey through the past, present, and future, guided by Professor Sean Carroll, noted author and Senior Research Associate in Physics at the California Institute of Technology.

    What exactly happened, such that Jesus came to be considered God?To ask this question is to delve into a fascinating, multilayered historical puzzle - one that offers a richly illuminating look into the origins of the Western worldview and the theological underpinnings of our civilization. This fundamental historical question and its complex answer speak penetratingly to the spiritual impulses, concerns, and beliefs that have played a seminal role in our world, even as they reveal the foundation of history's most global religious movement, and fresh insights into the Western world's single most influential human being.Tackling all of these matters and more, Great Courses favorite Professor Ehrman returns with the unprecedented historical inquiry of How Jesus Became God. In 24 provocative lectures, Professor Ehrman takes you deep into the process by which the divinity of Jesus was first conceived by his followers, demonstrating how this conception was refined over time to become the core of the Christian theology. A distinguished scholar of Christianity and New York Times best-selling author, Professor Ehrman develops the inquiry with meticulous research and in-depth analysis of texts. In these lectures, Ehrman reveals that the theological understanding of Jesus as God came about through a complex series of factors and events, each of which must be understood in order to grasp this most extraordinary and historically pivotal story.In the enthralling inquiry of How Jesus Became God Professor Ehrman lays bare the diverse elements that combined to produce both an astonishing true-life story and one of history's most significant developments. Join a renowned biblical scholar in grappling with this pivot.

    It seized all of Europe and much of the rest of the world in its grip of death and destruction.The first truly modern war, it changed how war and peace would be conducted throughout the remainder of the 20th century and even to the present. The Great War was a time of "firsts" and opened the door to the modern era. Almost all the major developed countries had a role to play in this war, as they never had before. This was the first time for fighting on land, at sea, and in the air. Modern weapons and munitions were developed in previously unimaginable quantities.By the end of the war, international politics, the relationships between the individual and the state, gender relations, and the role of artists and the media were all drastically changed. World War I laid the foundation for the modern world. This course examines the major events of the war to further understand how they led to the shaping of this new world.

    Modern science demonstrates that this mental hardwiring, traceable to the survival needs of our earliest ancestors, is at the root of many of the psychological and behavioral problems that we face today.For thousands of years, people have used mindfulness practices—techniques to develop awareness of present experience with acceptance—to deal effectively with a wide range of life challenges. And, a large and fascinating body of scientific research now validates the remarkable benefits of mindfulness practice for psychological as well as physical health.But how exactly does mindfulness work, in scientific terms? How can understanding the science and practice of mindfulness improve everyday life? And how can the human brain, whose very functioning gives rise to so many of the problems we struggle with, actually provide a solution?Now, in the 24 fascinating lectures of The Science of Mindfulness, Professor Ronald D. Siegel, a clinical psychologist on the faculty of Harvard Medical School, reveals the science behind mindfulness in compelling detail and demonstrates its application to an extraordinary range of human problems—psychological, social, and medical. You’ll closely examine the neurobiology involved, leaving you with a clear knowledge of the science underlying ancient practices that are now profoundly influencing the contemporary world. And you’ll learn many practical ways you can use mindfulness techniques in your own life.

    With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    Now - with the technological advances of modern archaeology and a new perspective on world history - we are finally able to piece together their compelling true stories. In Ancient Civilizations of North America, Professor Edwin Barnhart, Director of the Maya Exploration Center, will open your eyes to a fascinating world you never knew existed - even though you've been living right next to it, or even on top of it, for as long as you've been on the continent.The peoples of ancient North America were exceptionally knowledgeable about their environment, but their intellectual and artistic curiosity went much beyond the immediate need for food and safety. Beginning thousands of years ago, and without benefit of written language, native peoples became mathematicians, construction and soil engineers, astronomers, urban planners, and more. They developed thriving cities, extensive trade routes, canals to bring water to the desert, and earthworks we still marvel over today.In 24 exciting lectures, you'll learn about the vibrant cities of Poverty Point, the first city in North America, built about 3,500 years ago, and Cahokia, the largest city of ancient North America. You'll explore the many ways in which the Chacoan environment provided cultural and religious focus for peoples of the southwest. And you'll learn about the Iroquoian source of some of our most basic "American" values.

    This makes economic history - the study of how civilizations structured their environments to provide food, shelter, and material goods - a vital lens through which to think about how we arrived at our present, globalized moment.Designed to fill a long-empty gap in how we think about modern history, these 48 lectures are a comprehensive journey through more than 600 years of economic history, from the medieval world to the 21st century. Aimed at the layperson with only a cursory understanding of the field, An Economic History of the World since 1400 reveals how economics has influenced (and been influenced by) historical events and trends, including the Black Death, the Age of Exploration, the Industrial Revolution, the European colonization of Africa, the collapse of the Soviet Union, and the birth of personal computing. Professor Harreld has crafted a riveting, centuries-long story of power, glory, and ideology that reveals how, in step with history, economic ideas emerged, evolved, and thrived or died.Along the way, you'll strengthen your understanding of a range of economic concepts, philosophies, trends, treaties, and organizations, including the mercantile system, Adam Smith's The Wealth of Nations, Marxist economics, African independence movements, and the formation of economic organizations including the European Union. You'll also consider provocative questions about the intersection of history and economics. What did the economies of Roosevelt's America and Hitler's Germany have in common? What does history tell us about how nations should dictate economic policy? Can we say that free trade is truly free?Marvel at just how much we still have to learn about the economic forces that have dictated our past - and that will dictate our future.Listening Length: 24 hours and 29 minutes

    Someday, we know, we will all die. And, we know, so too will the universe itself.Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to understand it. Greene takes us on a journey across time, from our most refined understanding of the universe's beginning, to the closest science can take us to the very end. He explores how life and mind emerged from the initial chaos, and how our minds, in coming to understand their own impermanence, seek in different ways to give meaning to experience: in story, myth, religion, creative expression, science, the quest for truth, and our longing for the timeless, or eternal. Through a series of nested stories that explain distinct but interwoven layers of reality-from the quantum mechanics to consciousness to black holes-Greene provides us with a clearer sense of how we came to be, a finer picture of where we are now, and a firmer understanding of where we are headed.Yet all this understanding, which arose with the emergence of life, will dissolve with its conclusion. Which leaves us with one realization: during our brief moment in the sun, we are tasked with the charge of finding our own meaning.Let us embark.
