    King (William and Mary University) delves into the story of how, why, where, and when we became human. These lectures will help you understand the forces that have shaped, and continue to shape, our species. "An evolutionary perspective on human behavior," notes Dr. King, "results in more than just knowledge about dates and sites when and where specific evolutionary milestones likely occurred." "It is also a window on the past and future of our species. An entirely new way of thinking comes into focus when we consider the human species within an evolutionary perspective."A Century of ScholarshipWhile covering these subjects in this 24-lecture series, Dr. King synthesizes the best that more than a century of scientific scholarship has to offer across a variety of disciplines. Biological anthropologists study primate anatomy and behavior both to understand evolution and to learn more about our common ancestor. Biological anthropologists are joined by molecular anthropologists to better understand hominids by studying fossils, ancient skeletal remains, and lifestyle information such as cave art and stone tools. Case Studies that Clarify Evolution and Its Power Dr. King begins by explaining key mechanisms through which evolution functions, citing famous and definitive case studies that demonstrate these forces. In one such landmark study, for example, biologists Peter and Rosemary Grant returned to the Galapagos Islands more than 100 years after Darwin's first voyage to conduct research on island finches. In 1977, a drought-induced scarcity of soft, edible seeds brought forth in the very next generation a population of finches with larger, stronger beaks capable of crushing larger, tougher seeds. Extraordinarily, in 1985, heavy rains produced a surplus of softer seeds, and natural selection produced a succeeding generation of the smaller-beaked variety. Evolution had occurred in two different directions within a decade. This "natural selection" is the theoretical tool of evolution, which helps us make sense of these facts. Why Evolution Remains Important to Us Today Perhaps the greatest measure of this theory's power is its relevance to our lives today. - Did you know that the gene which causes sickle cell anemia must be inherited from both parents to cause the disease but the disease does not occur when only a single gene is inherited? - Or that the single gene, in fact, affords protection from malaria? Or that race, a category so securely ingrained in our consciousness, is practically meaningless in biological terms? - Or how to evaluate the claim that a gene can be responsible for a certain personality trait? A Glimpse Into Our Selected Primate Heritage With an understanding of the basic mechanisms of evolutionary change in hand, the course looks at how our ancient primate ancestors adapted. Consider the anatomical features we share with monkeys, great apes, and other primates. Our large brains, grasping hands, and forward-facing eyes allowing us to perceive depth are critical to the way we function in the world. Yet the fossil record tells us that some 70 million years ago these distinctive primate features did not exist. What caused the first primates to emerge from existing mammalian populations? One proposed solution was that the appearance of insects living in the lower canopies of trees offered a plentiful food resource to those species adapted to procure it. Could depth perception and grasping ability have provided an advantage here, and hence been naturally selected? This is the function of biological anthropology: confronting the facts, then suggesting and testing possibilities. A Course as Much About the Present as the PastWith so much of evolutionary history taken up with the past, the insights gained in these lectures may tempt you to add questions of your own: - Is human evolution still a force in today's world? Hasn't our modern, mobile culture rendered evolution irrelevant? - In fact, human evolution is a stronger force than ever, interacting with human culture in complex ways. Issues such as obesity, AIDS, and genetics are all discussed. And you may well find these lectures opening your eyes to the extraordinary ways in which the biological power of natural selection is still at work in the world today. Course Lecture Titles1.

    Fischer surveys anthropology, the study of human societies and comparative customs with a special emphasis on pre-capitalist societies and the things which pre-capitalist societies and modern societies have in common.

    What makes evolution such a profoundly provocative concept, so convincing to most scientists, yet so socially and politically divisive? The Theory of Evolution: A History of Controversy is an examination of the varied elements that so often make this science the object of strong sentiments and heated debate. Professor Edward J. Larson leads you through the "evolution" of evolution, with an eye toward enhancing your understanding of the development of the theory itself and the roots of the controversies that surround it. In these lectures you will: Explore pre-Darwinian theories of the origins of life, from Genesis and the ancient Greeks to such 18th- and 19th-century scientists as Georges Cuvier and Chevalier de Lamarck Follow the life and work of Charles Darwin, and the impact of his 1859 masterpiece, On the Origin of Species. Darwin's theory of evolution by natural selection was immediately recognized as a threat to traditional religion, but was quickly accepted (the first printing of Origin of Species sold out on the first day) Examine the history of evolutionary science after Darwin-a fascinating story that includes the "rediscovery," after 35 years, of Gregor Mendel's work on genetic variation; the unearthing of prehominid, or early human, fossils by Raymond Dart in 1925 and the Leakey family in the 1950s; and the confusion created by the sensational, but later discredited, discovery of Piltdown Man-a fake evolutionary "missing link"-in 1912 Trace the history of religious objections to evolution, from those of Darwin's own time to contemporary efforts to teach creation science in American schools. This includes a detailed discussion of the famous Scopes "monkey trial," which in fact was a staged media event, designed to create publicity for the town of Dayton, Tennessee. Are Our Genes more Important than We Are? This course makes it clear that the history of controversy surrounding evolution is not limited to a dispute between science and religion. Even within the scientific community, the fine details of the theory of evolution have long been a matter of passionate dispute. In fact, in the last third of the 19th century, the principal objections were scientific, not religious. Although the fossil record was a key piece of evidence for evolution, it had gaps that could be used to argue against the theory. And both proponents and critics wondered how altruistic human qualities such as love and generosity could possibly have evolved through the competitive, often harsh, processes that Darwin described. From Professor Larson's presentation, you will learn that new ideas in evolution science have often created new controversies. For example, is it truly possible, as some scientists now maintain, that humans exist merely to ensure the survival of their genes? Such research has created disagreement among scientists about the degree to which evolution drives human behavior, and has further alienated many segments of the public. Evolution's "Dark Side": Social Darwinism In these lectures, you will review perhaps the most sinister controversy associated with the theory of evolution: social Darwinism. From the beginning, the Darwinian theory of evolution has been linked to economic and political views. Thomas Malthus's theories of population growth and competition for limited resources even inspired Darwin's thinking on natural selection. Unfortunately, later supporters of evolution carried this line of thinking too far. Beginning with Herbert Spencer, who coined the term "survival of the fittest," Darwin's ideas were used as evidence for a wide range of social beliefs, from laissez-faire capitalism to racism, colonialism, and, in perhaps the worst application, Nazism. In the United States, social Darwinism has served as a basis for the creation of IQ tests and for eugenics programs that resulted in the forced sterilization of thousands of mentally ill or retarded Americans. Unsettling Implications: The Growing Gulf Between Science and Religion During the late 19th century, largely through the efforts of scientists who sought to integrate evolutionary science with spiritual belief, evolution was widely accepted by the religious community in the United States. Today, this is hardly the case. In his last four lectures, Professor Larson examines the trends that have, since 1920, widened the gulf between science and religion. These include an increase in fundamentalist Protestantism, the weakening of liberal Protestantism as a counteracting force, and the growing power of a firmly conservative South. In the 1960s, federally funded neo-Darwinian textbooks provoked a conservative backlash. Beginning with the publication of Henry M. Morris's The Genesis Flood, efforts to gain equal time for the teaching of creation science, based on biblical teachings, gathered strength. Rebuffed by the courts, creationism continues to thrive through the increasing numbers of private Christian schools and through home schooling. The growing gulf between science and religion has unsettling implications for our society. Large segments of the American population reject the naturalism of current evolutionary thinking. Nine of 10 Americans believe in spiritual causes for life, with only 10 percent accepting the purely naturalistic explanations espoused by evolution. Strikingly, these statistics are almost exactly the opposite among the scientific community. A Pulitzer Prize-Winning Teacher As both a historian of science and a professor of law, Professor Edward J. Larson brings exceptional qualifications to this subject. His book, Summer for the Gods: The Scopes Trial and America's Continuing Debate Over Science and Religion, won the 1998 Pulitzer Prize in History. His analysis provides an invaluable perspective on the volatile history of what is arguably the single most significant idea of modern times.

    This is a world tour of prehistory with profound links to who we are and how we live today.2.5 Million Years of HistoryThis 36-lecture narrative covers human prehistory from our beginnings more than 2.5 million years ago up to and beyond the advent of the world's first preindustrial civilizations.Due to the large spans of time and geography covered in this series, these lectures are divided into six sections:Section I: BeginningsThis section surveys the archaic world of the first humans, you travel into the remote past, learning why the late Harvard biologist Stephen Jay Gould was probably right to observe that we all come from the same African twig on the bushy tree of human evolution.You examine prehistory from Australopithecus africanus through Homo habilis (the first tool-making hominid), and Homo erectus (whose remains were first found on Java but whose origins lie in Africa) through the hardy Neanderthals who lived and hunted successfully in Europe despite the bitter grip of the last Ice Age 100,000 and more years ago. You focus on the first human settlement of Africa as early as 800,000 years ago.Section II: Modern HumansThis section tells the story of the great diaspora of anatomically modern humans in the late Ice Age. Whether and how these modern humans spread from the African tropics into southwestern Asia and beyond remains one of the great controversies among scholars of prehistory.You follow Homo sapiens sapiens north into Europe some 45,000 years ago. You meet the Cro-Magnons, among the first known artists as well as hunter-gatherers, who exhibited degrees of spiritual awareness, social interaction, and fluid intelligence.You venture into the frigid open plains of the Ukraine and Eurasia, where big-game hunters flourished in spite of nine-month winters. Moving to the Americas, debate over the origins of the first human settlement continues.Section III: Farmers and HerdersThis section describes perhaps the most important development in all human prehistory: the beginnings of agriculture and animal domestication.This defining chapter began about 12,000 years ago, when hunter-gatherers in the Near East broke from the long human tradition of intensely mobile foraging and turned to more settled ways of life built around cultivating cereal grains or tending animals.Section IV: Eastern Mediterranean CivilizationsProfessor Fagan describes early civilizations in an increasingly complex eastern Mediterranean world, discussing many theories accounting for the appearance of urban civilization and overall attributes of preindustrial civilizations.You examine Sumerian civilization in Mesopotamia and the intricate patchwork of city-states between the Tigris and Euphrates Rivers. You explore ancient Egypt, the Minoan civilization of Crete, the Mycenaeans, and the Hittites.You learn about the Uluburun shipwreck of southern Turkey, a sealed capsule of international trade from 3,000 years ago.Section V: Africans and AsiansYou analyze the beginnings of South Asian civilization and the mysterious Harappan civilization of the Indus, which traded with Mesopotamia. Professor Fagan resumes the story of South Asian civilization after the collapse of the Harappan and shows how Mauryan rulers on the Ganges encouraged trading much farther afield.You see the impact of monsoons which revolutionized maritime trading among Africa, India, and Southeast Asia, and explore Meroe, Aksum, and the coastal civilization of East Africa.Several lectures cover the beginnings of civilization in China and Southeast Asia.Section VI: Ancient AmericansProfessor Fagan takes you into sophisticated chiefdoms and civilizations that developed in the Americas over the past 3,500 years, including Pueblo cultures of the North American Southwest and the Mississippian culture of the South and Southeast. You learn about Mesoamerican civilization, primordial Olmec culture of the lowlands, and the spectacular ancient Maya civilization.Moving to the highlands, you visit the city-states of Monte Albán in the Valley of Oaxaca and Teotihuacán near the Valley of Mexico. Professor Fagan also describes the rise of Aztec civilization, followed by a journey to the Andes. Finally, you explore the southern highlands, with the rise of Tiwanaku near Lake Titicaca, the Chimu civilization of the coast, and the huge Inka empire.The series closes by analyzing the closing centuries of prehistoric times during the European age of discovery and summarizing the main issues and themes of the course: * What was involved in the archaic world * The appearance and spread of modern humans * Food production * The development of states.

    Yet, as the 1700s began, the mysteries of the universe were pondered by "natural philosophers"—the term "scientist" didn't even exist until the mid 19th century—whose explanations couldn't help but be influenced by the religious thought and political and social contexts that shaped their world.The radical ideas of the Enlightenment were especially important and influential. In this course you see how the work of these natural philosophers prepared the way for the more familiar world of science we recognize today.

    Kasser launches an ambitious and exciting inquiry into what makes science science, using the tools of philosophy to ask: * Why is science so successful? * Is there such a thing as the scientific method? * How do we distinguish science from pseudoscience? * Is science rational, cumulative, and progressive? Focusing his investigation on the vigorous debate over the nature of science that unfolded during the past 100 years, Professor Kasser covers important philosophers such as Karl Popper, W. V. Quine, Thomas Kuhn, Paul Feyerabend, Imre Lakatos, Carl Hempel, Nelson Goodman, and Bas van Fraassen.All of these thinkers responded in one way or another to logical positivism, the dominant movement influencing the philosophy of science during the first half of the 20 th century. Logical positivism attempted to ground science exclusively in what could be known through direct experience and logic.It sounds reasonable, but logical positivism proved to be riddled with serious problems, and its eventual demise is an object lesson in how truly difficult it is—perhaps impossible—to secure the logical foundations of a subject that seems so unassailably logical: science.

    Nothing you experience would be possible without the intricate power of your senses. But how much about them do you really know?Your ability to sense and perceive the world around you is so richly detailed and accurate as to be miraculous. No tool in the entire universe of scientific exploration can come close to matching the ability of your brain to use information sensed by your eyes, ears, skin, tongue, and nose to produce a rich sensory experience in just milliseconds.In recent years, neurobiologists and other scientists have uncovered new insights into how your senses work and the amazingly complex and fascinating things they can do. And now you can share in what they've discovered-through this intriguing series of 24 lectures from an award-winning teacher.Knowing how your senses work and the ways they shape how you see, interact with, and understand your life will help you think more critically about everything you sense and perceive, strengthen your appreciation of the senses that make this possible, prepare you to be an active consumer of new scientific evidence on how our senses work, and much more.With Professor Vishton as your guide, you'll. consider each of your senses from multiple perspectives:Explore how your brain processes different sensory informationConsider how your senses work together and within the context of the environment around youdiscover how your senses connect you to the world and other people.Using both cutting-edge research and simple experiments, tests, and demonstrations to hone your understanding, he has created a world-class learning experience that will change the way you think about your senses.

    Using the tools and knowledge of their field, archaeologists can now determine the nature of a sacrificial ritual, compare the visible attributes of ancient deities, and map out the orientation of a temple or tomb.Professor Hale gives you a comprehensive look at specific religious archaeological sites around the world-inside caves and crypts, through vast deserts and ancient cities, from Polynesia to Mexico to the American Midwest.Studying these breathtaking sites such as Lascaux Cave, Machu Picchu, and Easter Island, you learn the points of interest that attract the attention of archaeologists and scholars, survey the principal features unearthed during the site's excavation, discover what evidence at the site reveals about the evolution of religion, and more.By the final lap of your international journey, you'll have developed a new vision of religion and its crucial role in ancient history. You'll become more attuned to spirituality's universal elements and its unique characteristics. And you'll realize just how much credit religion deserves for remarkable sites that continue to captivate us.

    And in doing so, you’ll get a fresher understanding of an era in history with which we’re still trying to come to terms.How the Crusades Changed History plunges you into the series of Crusades to the Holy Land (and elsewhere), from the calling of the First Crusade in November 1095 until the collapse of the last crusader state, the Kingdom of Jerusalem, in 1291. Delivered by master medieval historian and award-winning professor Philip Daileader of The College of William & Mary, these 24 lectures are more than just an enriching recount of captivating historical events. They’re an intellectually rewarding exploration of the ways in which the Crusades shaped the history of the medieval world—and laid the seeds for our own.Dispel Misconceptions about the CrusadesThe Crusades remain lively topics of debate among historians and scholars, and they’re rife with contradictions and misconceptions that require us to peel back layers of history and confront some startling truths that go against what we traditionally think about medieval crusading.Take, for example, these points:Most Christians weren’t motivated to join the Crusades out of economic considerations but in hopes of gaining indulgences from the Catholic Church to decrease or eliminate time in purgatory.Crusading campaigns reached far beyond Jerusalem and the surrounding Holy Land, extending all along the Mediterranean and throughout much of northern Europe.The Crusades were not universally supported; rather, the period saw critics who questioned particular campaigns—many of which were disastrous failures.As you’ll learn with this course, these and other truths about the Crusades demonstrate that, rather than being grand wars, many of these military campaigns were tangled misadventures. And yet you’ll see that, for all their messiness, the Crusades made an indelible impact on the identity of Western civilization.A Fascinating, In-Depth HistoryProfessor Daileader spends the first 17 lectures of the course delivering a riveting in-depth narrative history of the Crusades that takes you in and around the medieval world and sweeps you up in the crusading fervor that led to some of the era’s most intriguing—and disastrous—campaigns. You’ll immerse yourself in the causes, battles, and consequences of the period’s major crusades—as well as some campaigns often overlooked.The First Crusade: Rather than a single expedition, the First Crusade was a series of loosely coordinated waves that left Europe over the space of several years after Pope Urban II’s initial call in 1095. More than 90% of those who were part of the First Crusade were not professional knights; rather, they were the populous, peasants and craftsmen led by a smattering of minor nobles and a popular preacher named Peter the Hermit.The Northern Crusades: Crusading was not just relegated to the Holy Land. Crusading campaigns also took place in parts of Europe. The Northern Crusades facilitated German and Christian expansion into eastern Europe and opened up a theater of war that was easier for crusaders to access than Syria and Palestine, but they siphoned off crusaders who might otherwise have worked to reclaim Jerusalem from the Ottoman Turks.The Children’s Crusade: One of the period’s oddest crusades, the Children’s Crusade of 1212 consisted primarily of processions of French youths—many between the ages of 6 and 14—carrying religious symbols toward Jerusalem to reclaim it for Christendom. More peaceful than other crusades, the Children’s Crusade lacked the militaristic overtones of other campaigns; medieval chroniclers make no mention of its participants bearing arms.View the Era with a More Inquisitive EyeOnce you reach the end of the major crusading period in the late 13th century, you take a step back in a series of thematic lectures that treat a host of topics with an inquisitive eye. Professor Daileader’s goal with this section of the course: to clarify your picture of the Crusades and to provide you with a stronger grasp of their broader historical consequences.You’ll get a chance to probe issues and questions that have intrigued historians for centuries:What did contemporary religious thinkers and critics say about the Crusades? What effects did their views have?What was the experience like for individuals who took up the crusader’s call? Why did they go? What did they take with them? How did they live day to day?How did everyday life in western Europe compare with that in the vulnerable crusader states?How did medieval Islam respond to the Crusades?By taking this approach, you’ll come to see how this frenetic period of warfare paved the way for subsequent historical movements and moments, including the centuries-long dominance of the Ottoman Empire, the Protestant Reformation, the prevalence of missionary campaigns around the world, and more.Learn from One of America’s Best ProfessorsHow the Crusades Changed History places you in the hands of a historian and teacher named one of the best professors in the United States by The Princeton Review and a four-time winner of Harvard University’s Certificate of Distinction in Teaching.Just minutes into the first lecture of this engaging course, you’ll find out why Professor Daileader’s lecturing style—filled with eye-opening insights, clear-cut explanations, gripping stories, and touches of ironic humor—has been praised by so many of our customers around the world.“Whether the Crusades deserve admiration, opprobrium, or something else entirely is a matter for individuals to decide for themselves,” notes Professor Daileader at the start of his engrossing lecture series. “Our goals are to understand the Crusades and to assess their consequences.”And by doing so with this course, you’ll have the knowledge necessary to come to your own conclusions about just how important and consequential these centuries of warfare were to Western civilization.
