News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    But the very existence of consciousness raises profound questions: Why would any collection of matter in the universe be conscious? How are we able to think about this? And why should we?In this wonderfully accessible book, Annaka Harris guides us through the evolving definitions, philosophies, and scientific findings that probe our limited understanding of consciousness. Where does it reside, and what gives rise to it? Could it be an illusion, or a universal property of all matter? As we try to understand consciousness, we must grapple with how to define it and, in the age of artificial intelligence, who or what might possess it. Conscious offers lively and challenging arguments that alter our ideas about consciousness—allowing us to think freely about it for ourselves, if indeed we can.

    After much consideration, we determined that it actually would be more beneficial to create a course that compares and contrasts the two major global economic theories, examining them in ways that move past the polemics many of us are used to and looking at these systems as they relate to one another and the world at large.Politics and economics are inextricable, so it can be difficult to find the right person to tackle such a complex and often polarizing subject as objectively as possible. Luckily, we found Professor Edward Stuart, an economist and teacher who specializes in comparative economics. Professor Stuart brings not only economic expertise, but personal experience gleaned from teaching, traveling, and consulting all over the world, and it is this wide lens of experience that helps make Capitalism vs. Socialism such an engaging new entry in our library of courses.

    Phill Juptitus talks about his personal word game habits, and we'll remember the late Humphrey Lyttelton's scurrilous account of Una Stubbs on I'm Sorry I Haven't a Clue.We'll travel deep inside the mind of puzzle-setter Chris Maslanka and visit the Comedy Store in London to experience the lightning reflexes of some top word-athletes. Plus, we'll examine an extraordinary claim—that the fashion for increasingly cryptic crosswords helped to defeat Hitler.Stephen Fry celebrates the fun side of the English language in this exclusive extended edition of a BBC Radio 4 special.

    Cavalli-Sforza and others have answered this question—anticipated by Darwin—with a decisive yes. Genes, Peoples, and Languages comprises five lectures that serve as a summation of the author's work over several decades, the goal of which has been nothing less than tracking the past hundred thousand years of human evolution.Cavalli-Sforza raises questions that have serious political, social, and scientific import: When and where did we evolve? How have human societies spread across the continents? How have cultural innovations affected the growth and spread of populations? What is the connection between genes and languages? Always provocative and often astonishing, Cavalli-Sforza explains why there is no genetic basis for racial classification.

    The 10,000 Year Explosion: How Civilization Accelerated Human Evolution

    And of a nation that fought a Civil War that freed its slaves, and outlawed segregation and discrimination.This is history shaped by Revolutionary War and Vietnam, Thomas Jefferson and William Jefferson Clinton, Puritanism and Feminism, Booker T. Washington and Martin Luther King, Jamestown and Disneyland, Harpers Ferry and Henry Ford, oil wells and Orson Welles.This is a review of the extraordinary blend of people, ideas, inventions, and events that comprise The History of the United States. In this seven-part, 84-lecture series, three noted historians and lecturers—two of whom teach other popular Teaching Company courses—present the nation's past through their areas of special interest.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    

    It's not just a list of "superfoods" or trendy exercises; the course takes a rigorous scientific approach to human vitality. Energy is a limited resource; learn to allocate yours in the best way possible to make the most of each day.

    But as renowned Yale surgeon and medical historian Sherwin B. Nuland shows in this brilliant collection of linked life portraits, the theory bears little resemblance to the truth. Through the centuries, the men and women who have shaped the world of medicine have been not only very human, but also very much the products of their own times and places. Presenting compelling studies of great medical innovators and pioneers, Doctors gives us a fascinating history of modern medicine. Ranging from the legendary Father of Medicine, Hippocrates, to Andreas Vesalius, whose Renaissance masterwork on anatomy offered invaluable new insight into the human body, to Helen Taussig, founder of pediatric cardiology and co-inventor of the original blue baby operation, here is a volume filled with the spirit of ideas and the thrill of discovery.

    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.

    By studying the physical astronomy of all the planets in the Solar System, we can attempt to understand their true nature. Ultimately, these lectures will bring us to a greater understanding of the Solar System's creation, which brings us again back to the beginning and what it means to us as we look outward from our rotating Earth.
