Available in PDF, EPUB and Kindle. Book excerpt: Resistance to malaria. Blue eyes. Lactose tolerance. What do all of these traits have in common? Every one of them has emerged in the last 10,000 years. Scientists have long believed that the “great leap forward” that occurred some 40,000 to 50,000 years ago in Europe marked end of significant biological evolution in humans. In this stunningly original account of our evolutionary history, top scholars Gregory Cochran and Henry Harpending reject this conventional wisdom and reveal that the human species has undergone a storm of genetic change much more recently. Human evolution in fact accelerated after civilization arose, they contend, and these ongoing changes have played a pivotal role in human history. They argue that biology explains the expansion of the Indo-Europeans, the European conquest of the Americas, and European Jews' rise to intellectual prominence. In each of these cases, the key was recent genetic change: adult milk tolerance in the early Indo-Europeans that allowed for a new way of life, increased disease resistance among the Europeans settling America, and new versions of neurological genes among European Jews. Ranging across subjects as diverse as human domestication, Neanderthal hybridization, and IQ tests, Cochran and Harpending's analysis demonstrates convincingly that human genetics have changed and can continue to change much more rapidly than scientists have previously believed. A provocative and fascinating new look at human evolution that turns conventional wisdom on its head, The 10,000 Year Explosion reveals the ongoing interplay between culture and biology in the making of the human race.

Available in PDF, EPUB and Kindle. Book excerpt: A breakthrough theory that tools and technology are the real drivers of human evolution Although humans are one of the great apes, along with chimpanzees, gorillas, and orangutans, we are remarkably different from them. Unlike our cousins who subsist on raw food, spend their days and nights outdoors, and wear a thick coat of hair, humans are entirely dependent on artificial things, such as clothing, shelter, and the use of tools, and would die in nature without them. Yet, despite our status as the weakest ape, we are the masters of this planet. Given these inherent deficits, how did humans come out on top? In this fascinating new account of our origins, leading archaeologist Timothy Taylor proposes a new way of thinking about human evolution through our relationship with objects. Drawing on the latest fossil evidence, Taylor argues that at each step of our species' development, humans made choices that caused us to assume greater control of our evolution. Our appropriation of objects allowed us to walk upright, lose our body hair, and grow significantly larger brains. As we push the frontiers of scientific technology, creating prosthetics, intelligent implants, and artificially modified genes, we continue a process that started in the prehistoric past, when we first began to extend our powers through objects. Weaving together lively discussions of major discoveries of human skeletons and artifacts with a reexamination of Darwin's theory of evolution, Taylor takes us on an exciting and challenging journey that begins to answer the fundamental question about our existence: what makes humans unique, and what does that mean for our future?
Download or read book When Humans Nearly Vanished written by Donald R. Prothero and published by Smithsonian Institution. This book was released on 2018-10-16 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fascinating true story of the explosion of the Mount Toba supervolcano--the Earth's largest eruption in the past 28 million years--and its lasting impact on Earth and human evolution Some 73,000 years ago, the huge dome of Mount Toba, in today's Sumatra, Indonesia, began to rumble. A deep vibration shook the entire island. Jets of steam and ash emanated from the summit, followed by an explosion louder than any sound heard by Homo sapiens since our species evolved on Earth. The eruption of the Toba supervolcano released the energy of a million tons of explosives; seven hundred cubic miles of magma spewed outward in an explosion forty times larger than the largest hydrogen bomb and more than a thousand times as powerful as the Krakatau eruption in 1883. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop by five to nine degrees. It took a full decade for Earth to recover to its pre-eruption temperatures. When Humans Nearly Vanished presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide. Human genes today show evidence of a "genetic bottleneck," an effect seen when a population of organisms becomes so small that their genetic diversity is greatly reduced. This group of survivors could be the ancestors of all humans alive today. Donald R. Prothero explores the geological and biological evidence supporting the Toba bottleneck theory; reveals how the explosion itself was discovered; and offers insight into how the world changed afterward and what might happen if such an eruption occurred today. Prothero's riveting account of this calamitous supervolcanic explosion is not to be missed.
Download or read book Hiroshima written by John Hersey and published by Vintage. This book was released on 2020-06-23 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hiroshima is the story of six people—a clerk, a widowed seamstress, a physician, a Methodist minister, a young surgeon, and a German Catholic priest—who lived through the greatest single manmade disaster in history. In vivid and indelible prose, Pulitzer Prize–winner John Hersey traces the stories of these half-dozen individuals from 8:15 a.m. on August 6, 1945, when Hiroshima was destroyed by the first atomic bomb ever dropped on a city, through the hours and days that followed. Almost four decades after the original publication of this celebrated book, Hersey went back to Hiroshima in search of the people whose stories he had told, and his account of what he discovered is now the eloquent and moving final chapter of Hiroshima.
Download or read book A Troublesome Inheritance written by Nicholas Wade and published by Penguin. This book was released on 2014-05-06 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on startling new evidence from the mapping of the genome, an explosive new account of the genetic basis of race and its role in the human story Fewer ideas have been more toxic or harmful than the idea of the biological reality of race, and with it the idea that humans of different races are biologically different from one another. For this understandable reason, the idea has been banished from polite academic conversation. Arguing that race is more than just a social construct can get a scholar run out of town, or at least off campus, on a rail. Human evolution, the consensus view insists, ended in prehistory. Inconveniently, as Nicholas Wade argues in A Troublesome Inheritance, the consensus view cannot be right. And in fact, we know that populations have changed in the past few thousand years—to be lactose tolerant, for example, and to survive at high altitudes. Race is not a bright-line distinction; by definition it means that the more human populations are kept apart, the more they evolve their own distinct traits under the selective pressure known as Darwinian evolution. For many thousands of years, most human populations stayed where they were and grew distinct, not just in outward appearance but in deeper senses as well. Wade, the longtime journalist covering genetic advances for The New York Times, draws widely on the work of scientists who have made crucial breakthroughs in establishing the reality of recent human evolution. The most provocative claims in this book involve the genetic basis of human social habits. What we might call middle-class social traits—thrift, docility, nonviolence—have been slowly but surely inculcated genetically within agrarian societies, Wade argues. These “values” obviously had a strong cultural component, but Wade points to evidence that agrarian societies evolved away from hunter-gatherer societies in some crucial respects. Also controversial are his findings regarding the genetic basis of traits we associate with intelligence, such as literacy and numeracy, in certain ethnic populations, including the Chinese and Ashkenazi Jews. Wade believes deeply in the fundamental equality of all human peoples. He also believes that science is best served by pursuing the truth without fear, and if his mission to arrive at a coherent summa of what the new genetic science does and does not tell us about race and human history leads straight into a minefield, then so be it. This will not be the last word on the subject, but it will begin a powerful and overdue conversation.
Download or read book The Big Ratchet written by Ruth DeFries and published by Basic Books. This book was released on 2014-09-09 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: How an ordinary mammal manipulated nature to become technologically sophisticated city-dwellers -- and why our history points to an optimistic future in the face of environmental crisis 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, 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. The Big Ratchet itself came in the twentieth century, when a range of technologies -- from fossil fuels to scientific plant breeding to nitrogen fertilizers -- combined to nearly quadruple our population in a century, and to grow our food supply even faster. To some, these technologies are a sign of our greatness; to others, of our hubris. MacArthur fellow and Columbia University professor Ruth DeFries argues that the debate is the wrong one to have. Limits do exist, but every limit that has confronted us, we have surpassed. That cycle of crisis and growth is the story of our history; indeed, it is the essence of The Big Ratchet. Understanding it will reveal not just how we reached this point in our history, but how we might survive it.
Download or read book Mean Genes written by Terry Burnham and published by Basic Books. This book was released on 2012-10-02 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Short, sassy, and bold, Mean Genes uses a Darwinian lens to examine the issues that most deeply affect our lives: body image, money, addiction, violence, and the endless search for happiness, love, and fidelity. But Burnham and Phelan don't simply describe the connections between our genes and our behavior; they also outline steps that we can take to tame our primal instincts and so improve the quality of our lives. Why do we want (and do) so many things that are bad for us? We vow to lose those extra five pounds, put more money in the bank, and mend neglected relationships, but our attempts often end in failure. Mean Genes reveals that struggles for self-improvement are, in fact, battles against our own genes -- genes that helped our cavewoman and caveman ancestors flourish but that are selfish and out of place in the modern world. Why do we like junk food more than fruit? Why is the road to romance so rocky? Why is happiness so elusive? What drives us into debt? An investigation into the biological nature of temptation and the struggle for control, Mean Genes answers these and other fundamental questions about human nature while giving us an edge to lead more satisfying lives.

Download or read book Who We Are and How We Got Here written by David Reich and published by Oxford University Press. This book was released on 2018-03-29 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past few years have witnessed a revolution in our ability to obtain DNA from ancient humans. This important new data has added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations living today are mixes of ancient ones, and often carry a genetic component from archaic humans. David Reich, whose team has been at the forefront of these discoveries, explains what genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial âpurity.' Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next?
Download or read book The Secret of Our Success written by Joseph Henrich and published by Princeton University Press. This book was released on 2017-10-17 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: How our collective intelligence has helped us to evolve and prosper Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals? This book shows that the secret of our success lies not in our innate intelligence, but in our collective brains—on the ability of human groups to socially interconnect and learn from one another over generations. Drawing insights from lost European explorers, clever chimpanzees, mobile hunter-gatherers, neuroscientific findings, ancient bones, and the human genome, Joseph Henrich demonstrates how our collective brains have propelled our species' genetic evolution and shaped our biology. Our early capacities for learning from others produced many cultural innovations, such as fire, cooking, water containers, plant knowledge, and projectile weapons, which in turn drove the expansion of our brains and altered our physiology, anatomy, and psychology in crucial ways. Later on, some collective brains generated and recombined powerful concepts, such as the lever, wheel, screw, and writing, while also creating the institutions that continue to alter our motivations and perceptions. Henrich shows how our genetics and biology are inextricably interwoven with cultural evolution, and how culture-gene interactions launched our species on an extraordinary evolutionary trajectory. Tracking clues from our ancient past to the present, The Secret of Our Success explores how the evolution of both our cultural and social natures produce a collective intelligence that explains both our species' immense success and the origins of human uniqueness.
Download or read book How to Avoid a Climate Disaster written by Bill Gates and published by Vintage. This book was released on 2021-02-16 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: #1 NEW YORK TIMES BEST SELLER • In this urgent, authoritative book, Bill Gates sets out a wide-ranging, practical—and accessible—plan for how the world can get to zero greenhouse gas emissions in time to avoid a climate catastrophe. Bill Gates has spent a decade investigating the causes and effects of climate change. With the help of experts in the fields of physics, chemistry, biology, engineering, political science, and finance, he has focused on what must be done in order to stop the planet's slide to certain environmental disaster. In this book, he not only explains why we need to work toward net-zero emissions of greenhouse gases, but also details what we need to do to achieve this profoundly important goal. He gives us a clear-eyed description of the challenges we face. Drawing on his understanding of innovation and what it takes to get new ideas into the market, he describes the areas in which technology is already helping to reduce emissions, where and how the current technology can be made to function more effectively, where breakthrough technologies are needed, and who is working on these essential innovations. Finally, he lays out a concrete, practical plan for achieving the goal of zero emissions—suggesting not only policies that governments should adopt, but what we as individuals can do to keep our government, our employers, and ourselves accountable in this crucial enterprise. As Bill Gates makes clear, achieving zero emissions will not be simple or easy to do, but if we follow the plan he sets out here, it is a goal firmly within our reach.

Book excerpt: “Meaty, well-written.” —Kirkus Reviews “Timely and informative.” —The New York Times Book Review “By far the best book I have ever read on humanity’s deep history.” —E. O. Wilson, biologist and author of The Ants and On Human Nature Nicholas Wade’s articles are a major reason why the science section has become the most popular, nationwide, in the New York Times. In his groundbreaking Before the Dawn, Wade reveals humanity’s origins as never before—a journey made possible only recently by genetic science, whose incredible findings have answered such questions as: What was the first human language like? How large were the first societies, and how warlike were they? When did our ancestors first leave Africa, and by what route did they leave? By eloquently solving these and numerous other mysteries, Wade offers nothing less than a uniquely complete retelling of a story that began 500 centuries ago.
Download or read book The Myth of the Jewish Race written by Raphael Patai and published by Wayne State University Press. This book was released on 1989 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this carefully researched analysis, Raphael and Jennifer Patai begin by defining race. They then develop the idea of the existence of "races" through history. In rich and fascinating detail, the authors consider the effects of intermarriage, interbreeding, proselytism, slavery, and concubinage on the Jewish population from Biblical times to the present. New material explores the psychological aspects of the Jewish race issue, the Jewish psyche, and the consequences of the 1975 United Nations resolution equating Zionism with racism. A revised and updated scientific section on the measurable genetic, morphological, and behavioral differences between Jews and non-Jews supports the conclusion that the idea of a "Jewish race" is, indeed, a myth.
