Even as banks may topple...even as the economy may be completely destroyed by greed and lack of shared sacrifice, Juan Enriquez says the big reboot is yet to come. But don't look for it on your ballot -- or in the stock exchange. It'll come from science labs, and it promises keener bodies and minds. Our kids and Grandkids are going to be ... different.

Having finished with slavery and the pro-slavery argument, Professor Blight heads North today. The majority of the lecture deals with the rise of the Market Revolution in the North, in the 1820s, 1830s, and 1840s. Blight first describes the causes of the Market Revolution--the rise of capital, a transportation revolution--and then moves to its effects on the culture and consciousness of antebellum northerners. Among these effects were a riotous optimism mixed with a deep-rooted fear of change, an embrace of the notions of progress and Manifest Destiny, and the intensification of the divides between North and South. The Civil War and Reconstruction (HIST 119) Complete course materials are available at the Open Yale Courses website: http://open.yale.edu/courses This course was recorded in Spring 2008.
Robert Sapolsky continues his series on molecular genetics in which he discusses domains of mutation and various components of natural selection on a molecular level. He also further assesses gradualism and punctuated equilibrium models of evolution, integrating these theories into an interrelated model of development.

In this two-hour special, NOVA captures the turmoil that tore apart the community of Dover, Pennsylvania in one of the latest battles over teaching evolution in public schools. Featuring trial reenactments based on court transcripts and interviews with key participants, including expert scientists and Dover parents, teachers, and town officials, "Judgment Day: Intelligent Design on Trial" follows the celebrated federal case of Kitzmiller v. Dover School District. This program was coproduced with Paul G. Allen's Vulcan Productions, Inc. In 2004, the Dover school board ordered science teachers to read a statement to high school biology students suggesting that there is an alternative to Darwin's theory of evolution called intelligent design--the idea that life is too complex to have evolved naturally and therefore must have been designed by an intelligent agent. The teachers refused to comply. Later, parents opposed to intelligent design filed a lawsuit in federal court accusing the school board of violating the constitutional separation of church and state. "There was a blow-up like you couldn't believe," Bill Buckingham, head of the school board's curriculum committee, tells NOVA. Buckingham helped formulate the intelligent-design policy when he noticed that the biology textbook chosen by teachers for classroom use was, in his words, "laced with Darwinism." NOVA presents the arguments by lawyers and expert witnesses in riveting detail and provides an eye-opening crash course on questions such as "What is evolution?" and "Is intelligent design a scientifically valid alternative?" Kitzmiller v. Dover was the first legal test of intelligent design as a scientific theory, with the plaintiffs arguing that it is a thinly veiled form of creationism, the view that a literal interpretation of the Bible accounts for all observed facts about nature. During the trial, lawyers for the plaintiffs showed that evolution is one of the best-tested and most thoroughly confirmed theories in the history of science, and that its unresolved questions are normal research problems--the type that arise in any flourishing scientific field. U.S. District Court Judge John E. Jones III ultimately decided for the plaintiffs, writing in his decision that intelligent design "cannot uncouple itself from its creationist, and thus religious, antecedents." As part of his decision, Judge Jones ordered the Dover school board to pay legal fees and damages, which were eventually set at $1 million. "Judgment Day captures on film a landmark court case with a powerful scientific message at its core," says Paula Apsell, NOVA's Senior Executive Producer. "Evolution is one of the most essential yet, for many people, least understood of all scientific theories, the foundation of biological science. We felt it was important for NOVA to do this program to heighten the public understanding of what constitutes science and what does not, and therefore, what is acceptable for inclusion in the science curriculum in our public schools." For years to come, the lessons from Dover will continue to have a profound impact on how science is viewed in our society and how it is taught in the classroom.
Professor Robert Sapolsky makes interdisciplinary connections between behavioral biology and molecular genetic influences. He relates protein synthesis and point mutations to micro-evolutionary change, and discusses conflicting theories of gradualism and punctuated equilibrium and the influence of epi-genetics on development theories.

Follow the trail of ancient Europeans! Dr Alice Roberts describes the various waves of anatomically modern humans that settled the continent of Europe. She crosses the Bosphorus and travels up the Danube River, following their likely route. She then describes the already resident population of Neanderthals, and visits Gibraltar, the last known site occupied by Neanderthals. She suggests that the principal difference between them and Homo sapiens was the latter's ability to create art, and visits the cave paintings at Lascaux. She discusses the theories about why Europeans have white skin and describes the birth of agriculture and the societal changes that took place as a result, visiting a spectacular Neolithic temple in Turkey. There are seven billion humans on Earth, spread across the whole planet. Scientific evidence suggests that most of us can trace our origins to one tiny group of people who left Africa around 70,000 years ago. When our species first arrived in Europe, the peak of the Ice Age was approaching and the continent was already crawling with a rival: stronger, at home in the cold and even (contrary to the popular image) brainier than us. So how did the European pioneers survive first the Neanderthals and then the deep freeze as they pushed across the continent? Alice Roberts reconstructs the head of the 'first European' to come face to face with one of our ancestors; she discovers how art became crucial for survival in the face of Neanderthal competition; and what happened to change the skin colour of these European pioneers. Finally, spectacular new finds on the edge of Europe suggest that the first known temples may have been a spark for a huge revolution in our ancestors' way of life - agriculture.

Dr Alice Roberts travels the globe to discover the incredible story of how humans left Africa to colonize the world. Alice Roberts travels to Siberia and visits an isolated community of indigenous people who still practice reindeer hunting. With reference to them, she asks how ancient Africans could have adapted to the hostile climate of northern Asia, and why Asian people look so different from Africans. Roberts then explores an alternative to the Out of Africa theory, the multiregional hypothesis that has gained support in some scientific communities in China. According to this theory, the Chinese are descended from a human species called Homo erectus rather than from the Homo sapiens from which the rest of humanity evolved. Roberts visits the Zhoukoudian caves, in which Peking Man, the supposed Homo erectus ancestor of the Chinese, was discovered. Roberts notes that some Chinese anthropologists and palaeontologists have shown modern Chinese physical characteristics in the fossil skulls, such as broad cheek bones, cranial skull shape and shovel-shaped incisors that are absent in almost all other humans. She also notes that the stone tools found in China seem more primitive than those elsewhere, and infers that they were made exclusively by Homo erectus. However, she argues that the skull evidence is only subtle. She interviews an American palaeontologist, who presents his hypothesis that the ancient Chinese humans used bamboo instead of stone, explaining the absence of sophisticated stone tools, despite the absence of archaeological evidence to support this hypothesis. Finally, Roberts interviews Chinese geneticist Jin Li, who ran a study of more than 10,000 individuals scattered throughout China from 160 ethnic groups. The study initially hypothesised that the modern Chinese population evolved from Homo erectus in China but concluded that the Chinese people did in fact evolve and migrate from Africa like the rest of world's population.
