Genetic History

The Big Ratchet is the story of the ratchets: the technologies and innovations, big and small, that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket. Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened.

The question of teaching evolution in the public schools is a continuing and frequently heated political issue in America. From Tennessee's Scopes Trial in 1925 to recent battles that have erupted in Louisiana, Kansas, Ohio, and countless other localities, the critics and supporters of evolution have fought nonstop over the role of science and religion in American public life. In American Genesis, Jeffrey P. Moran explores the ways in which the evolution debate has reverberated beyond the confines of state legislatures and courthouses.

In December 1929, in a cave near Peking, a group of anthropologists and archaeologists that included a young French Jesuit priest named Pierre Teilhard de Chardin uncovered a prehuman skull. The find quickly became known around the world as Peking Man and was acclaimed as the missing link between erect hunting apes and our Cro-Magnon ancestors. It also became a provocative piece of evidence in the roiling debate over creationism versus evolution.

In this provocative history of contemporary debates over evolution, veteran journalist Tom Bethell depicts Darwin's theory as a 19th-century idea past its prime, propped up by logical fallacies, bogus claims, and empirical evidence that is all but disintegrating under an onslaught of new scientific discoveries. Bethell presents a concise yet wide-ranging tour of the flash points of modern evolutionary theory. Bethell's account is enriched by his own personal encounters with of some of our era's leading scientists and thinkers.

Fifty thousand years ago - merely a blip in evolutionary time - our Homo sapiens ancestors were competing for existence with several other human species, just as their precursors had done for millions of years. Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special.

Evolution is one of the most important processes in life. It not only explains the detailed history of life on earth, but its scope also extends into many aspects of our own contemporary behavior - who we are and how we got to be here, our psychology, our cultures - and greatly impacts modern advancements in medicine and conservation biology. Perhaps its most important claim for science is its ability to provide an overarching framework that integrates the many life sciences into a single unified whole. Yet, evolution has been, and continues to be, regarded with suspicion by many.

Brains Through Time examines how vertebrate nervous systems evolved in conjunction with other organ systems and the planet's ecology. Surveying an enormous range of information on genes and proteins, sensory and motor systems, central neural circuits, physiology, and animal behavior, the authors reconstruct the major changes that occurred as vertebrates emerged and then diversified.

Who decides where we are born and who we love? Luna is an immortal entity in the Upperworld learning how to assign human souls to the body and life they’re intended for. Onyx is her mentor and guide there, teaching her everything she needs to know about assigning souls and dispatching them to Earth. Everything goes well until Luna’s friend makes a major mistake and Luna is sent to earth after covering for her. In her absence, an unbelievable secret is revealed that changes everything she thought she knew about how the world works.

Does human life have any meaning? Does the question even make sense today? For centuries, the question of the meaning or purpose of human life was assumed by scholars and theologians to have a religious answer: Life has meaning because humans were made in the image of a good god. In the 19th century, however, Charles Darwin's theory of evolution changed everything - and the human organism was seen to be more machine than spirit.

Vor 65 Millionen Jahren stürzte ein großer Meteorit nahe der mexikanischen Halbinsel Yucatán auf die Erde. Das war das Ende der Dinosaurier und von etwa 90 Prozent allen Lebens. Es war auch das Ende einer Zivilisation, von der wir heute nichts mehr wissen. Aber diese Vor-Menschen haben ihren Nachfolgern ein Erbe hinterlassen: zwölf Container, sicher verborgen auf dem Mond. Der Inhalt: Unschätzbar wertvoll. Jetzt ist es soweit: "Das Erbe der ersten Menschheit" wird geborgen und die Entdeckungen beginnen. Sind Sie dabei?

From the Siberian permafrost to balmy California, scientists across the globe are working to resurrect all kinds of extinct animals, from ones that just left us to those that have been gone for many thousands of years. Their tools in this hunt are both fossils and cutting-edge genetic technologies. Some of these scientists are driven by sheer curiosity; others view the lost species as a powerful weapon in the fight to preserve rapidly changing ecosystems. It seems certain that these animals will walk the earth again, but what world will that give us? And is any of this a good idea?

Impressive Deception offers an inside look at the deceiving portrayal of evolution by the media and in our public schools. DeeDee Briski uncovers the media bias that forms the basis of the worldview that has become the accepted view in our mainstream educational systems.

They say curiosity killed the cat. But according to The Curiosity Gene, inquisitiveness actually plays the opposite role - responsible for not only human survival but also our evolutionary advancement to become the most intelligent creature on the planet. This groundbreaking new book by award-winning science writer and computer engineer Alexandros Kourt combines anthropology, archaeology, psychology, and evolution with computer theory to help listeners better understand themselves and the human brain.

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 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

Scientists often challenge conventional wisdom and spark debates that last for generations. But no scientist has fuelled more debate than Charles Darwin. To some he is the revolutionary 'father' of evolution. To others he is the perverse 'originator' of modern eugenics. In The Darwin Myth: The Life and Lies of Charles Darwin, author Benjamin Wiker brings these conflicting identities to light.

It was the most radical human-breeding experiment in American history, and no one knew how it turned out. The Repository for Germinal Choice, nicknamed the Nobel Prize sperm bank, opened to notorious fanfare in 1980, and for two decades, women flocked to it from all over the country to choose a sperm donor from its roster of Nobel-laureate scientists, mathematical prodigies, successful businessmen, and star athletes.

Humans are the only species who can reprogram themselves. This is astounding. In episode 8 of The Book Club, Amit Varma recommends you read 'Hacking Darwin' by Jamie Metzl, a lucid summation of the technological implications of genetic science – and the ethical questions they raise.

The field of biotechnology has evolved over the past four decades, developing medicines which are curing diseases. But this journey of success has been tough and arduous, built upon the shoulders of major failures.

Spectacular fossil finds make today's headlines; new technology unlocks secrets of skeletons unearthed 100 years ago. Still, evolution is often poorly represented by the media and misunderstood by the public. A potent antidote to pseudoscience, Written in Stone is an engrossing history of evolutionary discovery for anyone who has marveled at the variety and richness of life.

The current controversy over teaching evolution in the public schools has grabbed front-page headlines and topped news broadcasts all across the United States. In the Beginning investigates the movement that has ignited debate in state legislatures and at school board meetings. Reaching back to the origins of antievolutionism in the 1920s, and continuing to the promotion of intelligent design today, Michael Lienesch skillfully analyzes one of the most formidable political movements of the 20th century.
