"It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating—the best known of these methods—and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves—James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson—Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.

    Members of a parallel humanity that evolved in Europe for hundreds of thousands of years, they were in direct competition with Cro-Magnons — modern humans. The way Neanderthals lived and the reasons why they disappeared 50,000 years ago offer a surprising mirror in which we can examine and learn more about ourselves. Illustrated, concise and readable, this is a fascinating exploration of human origins. "Lively, personal, refreshing, and instructive, this book should be read by anyone interested in their own origins and our extinct relatives." — Ian Tattersall, author of The Fossil Trail, The Last Neanderthal, and Becoming Human

    Radiometric dating of nearby rocks indicated the skeleton, classified as Ardipithecus ramidus, was 4.4 million years old, more than a million years older than "Lucy," then the oldest known human ancestor. The findings challenged many assumptions about human evolution--how we started walking upright, how we evolved our nimble hands, and, most significantly, whether we were descended from an ancestor that resembled today's chimpanzee--and repudiated a half-century of paleoanthropological orthodoxy.Fossil Men is the first full-length exploration of Ardi, the fossil men who found her, and her impact on what we know about the origins of the human species. It is a scientific detective story played out in anatomy and the natural history of the human body. Kermit Pattison brings into focus a cast of eccentric, obsessive scientists, including one of the world's greatest fossil hunters, Tim White--an exacting and unforgiving fossil hunter whose virtuoso skills in the field were matched only by his propensity for making enemies; Gen Suwa, a Japanese savant who sometimes didn't bother going home at night to devote more hours to science; Owen Lovejoy, a onetime creationist-turned-paleoanthropologist; Berhane Asfaw, who survived imprisonment and torture to become Ethiopia's most senior paleoanthropologist and who fought for African scientists to gain equal footing in the study of human origins; and the Leakeys, for decades the most famous family in paloanthropology.An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa and a nation caught in a brutal civil war, to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must read for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.

    Here Hoagland redefines the solar system as a different place than NASA has presented. The book includes a new preface covering the Mars Global Surveyor photos and NASA's reactions.

    Neither the Griffon nor the five-man crew was ever seen again. Though the Griffon’s fate remains a mystery, its disappearance was probably the result of the first shipwreck on a Great Lake.Since then, more than six thousand vessels, large and small, have met tragic ends on the Great Lakes. For many years, saltwater mariners scoffed at the freshwater sailors of the Great Lakes, “puddles” compared to the vast oceans. But those who actually worked on the Great Lakes ships knew differently.Shoals and reefs, uncharted rocks, and sandbars could snare a ship or rip open a hull. Unpredictable winds could capsize a vessel at any moment. A ship caught in a storm had much less room to maneuver than did one at sea. The wreckage of ships and the bones of the people who sail them litter the bottoms of the five lakes: Ontario, Erie, Huron, Michigan, and Superior. Ed Butts has gathered stories and lake lore in this fascinating, frightening volume. For anyone living on the shores of the Great Lakes, these tales will inspire a new interest and respect for their storied past.

    "Reading The Neanderthal Enigma is like sitting down with a wonderful storyteller in the cave where stories began." -- Jonathan Weiner, author of The Beak of the Finch..

    Gases and dust particles ejected into the atmosphere changed weather patterns around the world, resulting in the infamous ''year without a summer'' in North America, food riots in Europe, and a widespread cholera epidemic. And the gloomy weather inspired Mary Shelley to write the gothic novel Frankenstein.This book tells the story of nine such epic volcanic events, explaining the related geology for the general reader and exploring the myriad ways in which the earth's volcanism has affected human history. Zeilinga de Boer and Sanders describe in depth how volcanic activity has had long-lasting effects on societies, cultures, and the environment. After introducing the origins and mechanisms of volcanism, the authors draw on ancient as well as modern accounts--from folklore to poetry and from philosophy to literature. Beginning with the Bronze Age eruption that caused the demise of Minoan Crete, the book tells the human and geological stories of eruptions of such volcanoes as Vesuvius, Krakatau, Mount Pel�e, and Tristan da Cunha. Along the way, it shows how volcanism shaped religion in Hawaii, permeated Icelandic mythology and literature, caused widespread population migrations, and spurred scientific discovery.From the prodigious eruption of Thera more than 3,600 years ago to the relative burp of Mount St. Helens in 1980, the results of volcanism attest to the enduring connections between geology and human destiny.

    Accompanied by video, photographs, and audio evidence, the story is written in Christine’s own words as it unfolds. According to the Bigfoot investigator they contacted, “They aren’t going anywhere.” As the world gets more crowded with us, “They” are left with less and less habitat. They have learned to live in the shadows and pass through the forests by our homes. After reading this book just ask yourself, what would you do if this happened to you? This story is not embellished or fictionalized. It is a series of true events interpreted and told from the author's point of view.

    Jacobs of Temple University takes us into the private world of those abducted by aliens, letting them describe in their own words what it is like to be abducted. Based on interviews with sixty individuals and more than 300 independently corroborated accounts, Secret Life presents the most complete and accurate picture of alien abductions ever compiled. Dr. Jacobs takes the reader on a minute-by-minute journey through a typical abduction experience and describes in detail the bizarre physical, mental and reproductive procedures that abductees claim have been administered by small alien beings. Jacobs draws from these interviews a profoundly unsettling reason behind the abductions: aliens are conducting a complex reproductive experiment involving the conception, gestation. or incubation of human and alien hybrid beings.

    Krause is a pioneer in the revolutionary new science of archaeogenetics, archaeology augmented by revolutionary DNA sequencing technology, which has allowed scientists to uncover a new version of human history reaching back more than 100,000 years. Using this technology to re-examine human bones from the distant past, Krause has been able to map not only the genetic profiles of the dead, but also their ancient journeys.In this concise narrative he tells us their long-forgotten stories of migration and intersection. It's well known that many human populations carry genetic material from Neanderthals; but, as Krause and his colleagues discovered, we also share DNA with a newly uncovered human form, the Denisovans. We know now that a wave of farmers from Anatolia migrated into Europe 8,000 years ago, essentially displacing the dark-skinned, blue-eyed hunter-gatherers who preceded them. The farmer DNA is one of the core genetic components of contemporary Europeans and European Americans. Though the first people to cross into North and South America have long been assumed to be primarily of East Asian descent, we now know that they also share DNA with contemporary Europeans and European Americans. Genetics has an unfortunate history of smuggling in racist ideologies, but our most cutting-edge science tells us that genetic categories in no way reflect national borders.Krause vividly introduces us to prehistoric cultures such as the Aurignacians, innovative artisans who carved animals, people, and even flutes from bird bones more than 40,000 years ago; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt; and the Gravettians, big-game hunters who were Europe's most successful early settlers until they perished in the ice age. This informed retelling of the human epic confirms that immigration and genetic mingling have always defined our species and that who we are is a question of culture not genetics.

    . . . Gould is the Stan Musial of essay writing. He can work himself into a corkscrew of ideas and improbable allusions paragraph after paragraph and then, uncoiling, hit it with such power that his fans know they are experiencing the game of essay writing at its best."--John Noble Wilford, New York Times Book Review

    An accidental tea spill damages the royal papyrus she has been struggling to interpret, the papyrus purported to be Queen Tiye’s last message to her son, Tutankhamun. But the spill also exposes hidden writing below the surface hieroglyphs. Horrified at the damage but aching to read the entire secret text, Rika agrees to let visiting remote-sensing expert David Chamberlain smuggle the priceless document out of the museum and scan it with instruments on his aircraft. The results are stunning. They show Tiye, previously a footnote in history, to have been the power behind the thrones of her husband and sons, as well as the architect of a monotheistic religion unique in ancient Egypt. Riveted by these revelations, Rika and David devise a covert plan to locate Tiye’s tomb. But Major Hassam of the Egyptian Secret Police misreads their activities as a plot to overthrow the government and vows to stop them at all costs. Reared in revolution, Rika feels a spiritual bond with Tiye, an African commoner who revolutionized Egyptian society by introducing a religion that freed Egypt from the tyranny of the Amun priests. Rika’s quest to find Tiye’s tomb parallels the queen’s last journey up the Nile, three thousand years before, to be buried alive in a tomb like no other. In a league with Michael Crichton, Dan Brown, and Wilbur Smith, John Oehler has created a cinematic page-turner of explosive yet poetic brilliance. And readers who liked Lisbeth Salander in Stieg Larsson’s The Girl with the Dragon Tattoo, will love Rika. Papyrus was a semi-finalist in the 2009 Amazon Breakthrough Novel Award competition (top 1% of 10,000 entries) and garnered more than a hundred 5-star reviews.

    It seems the more our maps of the known world get filled in, the more we crave mysterious locations full of strange creatures.Enter Colin Dickey, Cultural Historian and Tour Guide of the Weird. With the same curiosity and insight that made Ghostland a hit with readers and critics, Colin looks at what all fringe beliefs have in common, explaining that today's Illuminati is yesterday's Flat Earth: the attempt to find meaning in a world stripped of wonder. Dickey visits the wacky sites of America's wildest fringe beliefs--from the famed Mount Shasta where the ancient race (or extra-terrestrials, or possibly both, depending on who you ask) called Lemurians are said to roam, to the museum containing the last remaining "evidence" of the great Kentucky Meat Shower--investigating how these theories come about, why they take hold, and why as Americans we keep inventing and re-inventing them decade after decade. The Unidentified is Colin Dickey at his best: curious, wry, brilliant in his analysis, yet eminently readable.

    In Café Neandertal, Bahrami follows this compelling riddle along a path populated with colorful local personalities and opinionated, polemical, and brilliant archaeologists working in remote and fascinating places across Eurasia, all the while maintaining a firm foothold in the Dordogne, a region celebrated by the local tourist office as a vacation destination for 400,000 years. From this prehistoric perch Bahrami gets to know first-hand the Neandertals and the people who love them — those who have devoted their lives to them. She is thrown into a world debating not only what happened to these close cousins but also what legacy they have left for those who followed.Café Neandertal is also a detective story, investigating one of the biggest mysteries of prehistory and archaeology: Who were the Neandertals? Why did they disappear around 35,000 years ago? And more mysteriously, what light do they shed on us moderns?Bahrami takes readers into the thick of an excavation, neck-deep in Neanderthal dirt, and to the front row of the heated debates about our long-lost cousins. Café Neandertal pulls us deeply into the complex mystery of the Neandertals, shedding a surprising light on what it means to be human.
