Hardback. Condición: Very Good. For 65 million years dinosaurs ruled the Earth--until a deadly asteroid forced their extinction. But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures--real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment--a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story.…

Condición: Good. According to University of Washington paleontologist Peter D. Ward, all but one of the major extinction events in the history of the world have been brought on by climate change-the same global warming that occurs today. In Under a Green Sky, he examines the causes of the Permian extinction, an event more than 200 million years ago so cataclysmic that it destroyed more than 90% of all species and nearly 97% of all living things. This near-total devastation was caused by a warming of the earth due to rising levels of carbon dioxide. Ward explains how that extinction, as well as four others, happened, and then applies those chilling lessons to the present day, showing how the ancient past may hold the key to earth's future.…

Paperback. Condición: Good. More than 200 million years ago, a cataclysmic event known as the Permian extinction destroyed more than 90% of all species and nearly 97% of all living things. Its origins have long been a puzzle for paleontologists, and during the 1990s and the early part of this century a great battle was fought between those who thought that death had come from above and those who thought something more complicated was at work. Paleontologist Peter D. Ward, fresh from helping prove that an asteroid had killed the dinosaurs, turned to the Permian problem, and he has come to a stunning conclusion. In his investigations of the fates of several groups of mollusks during those extinctions and others, he discovered that the near-total devastation at the end of the Permian was caused by rising levels of carbon dioxide leading to climate change. But it's not the heat (nor the humidity) that's directly responsible for the extinctions, and the story of the discovery of what is responsible makes for an fascinating, globe-spanning adventure.…

Hardback. Condición: Good. They deftly bring together findings from many disparate areas of science in a book that science buffs will find hard to put down. --Publishers Weekly Science has worked hard to piece together the story of the evolution of our world up to this point, but only recently have we developed the understanding and the tools to describe the entire life cycle of our planet. Peter D. Ward and Donald Brownlee, a geologist and an astronomer respectively, are in the vanguard of the new field of astrobiology. Combining their knowledge of how the critical sustaining systems of our planet evolve through time with their understanding of how stars and solar systems grow and change throughout their own life cycles, the authors tell the story of the second half of Earth's life. In this masterful melding of groundbreaking research and captivating, eloquent science writing, Ward and Brownlee provide a comprehensive portrait of Earth's life cycle that allows us to understand and appreciate how the planet sustains itself today, and offers us a glimpse of our place in the cosmic order.…

Hardback. Condición: Good. Epigenetics upends natural selection and genetic mutation as the sole engines of evolution, and offers startling insights into our future heritable traits. In the 1700s, Jean-Baptiste Lamarck first described epigenetics to explain the inheritance of acquired characteristics; however, his theory was supplanted in the 1800s by Darwin's theory of evolution by natural selection through heritable genetic mutations. But natural selection could not adequately explain how rapidly species re-diversified and repopulated after mass extinctions. Now advances in the study of DNA and RNA have resurrected epigenetics, which can create radical physical and physiological changes in subsequent generations by the simple addition of a single small molecule, thus passing along a propensity for molecules to attach in the same places in the next generation. Epigenetics is a complex process, but paleontologist and astrobiologist Peter Ward breaks it down for general readers, using the epigenetic paradigm to reexamine how the history of our species--from deep time to the outbreak of the Black Plague and into the present--has left its mark on our physiology, behavior, and intelligence. Most alarming are chapters about epigenetic changes we are undergoing now triggered by toxins, environmental pollutants, famine, poor nutrition, and overexposure to violence. Lamarck's Revenge is an eye-opening and provocative exploration of how traits are inherited, and how outside influences drive what we pass along to our progeny.…

Paperback. Condición: Very Good. No matter what efforts we make to halt global warming, sea level rise will be an unavoidable part of our future. In The Flooded Earth , species extinction expert Peter D. Ward describes in intricate detail what our world will look like in 2050, 2100, 2300, and beyond. Even if we stopped all carbon dioxide emissions today, according to Ward, the seas will rise three feet by 2050 and nine feet by 2100. The effects of one meter of sea-level rise will be massive three meters will be catastrophic. Incursions of salt into the water table will destroy most of our best agricultural land, and corrosion will devour the electrical and fiber-optic systems of coastal cities, as well as our roads and bridges. Amsterdam, Miami, Venice and other cities might have to be abandoned. As icebound regions melt, meanwhile, new sources of oil, gas, minerals, and arable land will be revealed,and geopolitical battles will erupt over who owns the rights to them. Laying out a blueprint for a foreseeable future, Ward explains what politicians and policy makers around the world should be doing now to head off the worst consequences of this cataclysmic,and frighteningly inevitable,transformation.…

Paperback. Condición: Very Good. Why are the great mammals that once walked the earth now largely extinct outside of Africa? Of the two suspected culprits, climate change and human hunting, Ward builds a compelling case for human hunting. Humans arrived in Australia about 40,000 years ago, and the marsupial lions and giant kangaroos vanished soon after; they came to New Zealand 2,000 years ago, and the giant moa was quickly gone; and the American extinction coincides with the spread of the first human population there. In order to understand what happened in the Ice Age, Ward takes us on a tour of mass extinctions through earth's history. He presents a compelling account of the great comet crash that killed off the dinosaurs and describes other extinctions that were even worse. In so doing he introduces us to a profound paradigm shift now taking place in paleontology: rather than arising from the gradual workings of everyday forces, all mass extinctions are due to unique, catastrophic events. They throw a wild card into the game of evolution and start the contest anew.…
