Meave Leakey's thrilling, high-stakes memoir--written with her daughter Samira--encapsulates her distinguished life and career on the front lines of the hunt for our human origins, a quest made all the more notable by her stature as a woman in a highly competitive, male-dominated field.
Sediments of Time features the most important essays by renowned German historian Reinhart Koselleck not previously available in English, several of them essential to his theory of history. The volume sheds new light on Koselleck's crucial concerns, including his theory of sediments of time; his theory of historical repetition, duration, and acceleration; his encounters with philosophical hermeneutics and political and legal thought; his concern with the limits of historical meaning; and his views on historical commemoration, including that of the Second World War and the Holocaust. A critical introduction addresses some of the challenges and potentials of Koselleck's reception in the Anglophone world.
"Riveting. ... Pattison's uncanny ability [is] to write evocatively about science. ... In this, he is every bit as good as the best scientist writers." —New York Times Book Review (Editors' Choice) "Brilliant. ... A work of staggering depth." —Minneapolis Star Tribune A decade in the making, Fossil Men is a scientific detective story played out in anatomy and the natural history of the human body: the first full-length account of the discovery of a startlingly unpredicted human ancestor more than a million years older than Lucy It is the ultimate mystery: where do we come from? In 1994, a team led by fossil-hunting legend Tim White uncovered a set of ancient bones in Ethiopia’s Afar region. Radiometric dating of nearby rocks indicated the resulting skeleton, classified as Ardipithecus ramidus—nicknamed “Ardi”—was an astounding 4.4 million years old, more than a million years older than the world-famous “Lucy.” The team spent the next 15 years studying the bones in strict secrecy, all while continuing to rack up landmark fossil discoveries in the field and becoming increasingly ensnared in bitter disputes with scientific peers and Ethiopian bureaucrats. When finally revealed to the public, Ardi stunned scientists around the world and challenged a half-century of orthodoxy 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. But the discovery of Ardi wasn’t just a leap forward in understanding the roots of humanity--it was an attack on scientific convention and the leading authorities of human origins, triggering an epic feud about the oldest family skeleton. In Fossil Men, acclaimed journalist Kermit Pattison brings us a cast of eccentric, obsessive scientists, including White, an uncompromising perfectionist whose virtuoso skills in the field were matched only by his propensity for making enemies; Gen Suwa, a Japanese savant whose deep expertise about teeth rivaled anyone on Earth; Owen Lovejoy, a onetime creationist-turned-paleoanthropologist with radical insights into human locomotion; Berhane Asfaw, who survived imprisonment and torture to become Ethiopia’s most senior paleoanthropologist; Don Johanson, the discoverer of Lucy, who had a rancorous falling out with the Ardi team; and the Leakeys, for decades the most famous family in paleoanthropology. Based on a half-decade of research in Africa, Europe and North America, Fossil Men is not only a brilliant investigation into the origins of the human lineage, but the oldest of human emotions: curiosity, jealousy, perseverance and wonder.

From individual grains to desert dunes, from the bottom of the sea to the landscapes of Mars, and from billions of years in the past to the future, this is the extraordinary story of one of nature's humblest, most powerful, and most ubiquitous materials. Told by a geologist with a novelist's sense of language and narrative, Sand examines the science—sand forensics, the physics of granular materials, sedimentology, paleontology and archaeology, planetary exploration—and at the same time explores the rich human context of sand. Interwoven with tales of artists, mathematicians, explorers, and even a vampire, the story of sand is an epic of environmental construction and destruction, an adventure in staggering scales of time and distance, yet a tale that encompasses the ordinary and everyday. Sand, in fact, is all around us—it has made possible our computers, buildings and windows, toothpaste, cosmetics, and paper, and it has played dramatic roles in human history, commerce, and imagination. In this luminous, kinetic, revelatory account, we do indeed find the world in a grain of sand.
This volume provides a comprehensive overview of the rapidly developing field of microbial sediments, featuring excellent artwork. It contains authoritative and stimulating contributions by distinguished authors that cover the field and set the scene for future advances.
Much the way Donald Hall’s Seasons at Eagle Pond captured New England, Sky Time in Gray’s River captures the essence of the rural Northwest. Although Rober Michael Pyle is a lepidopterist, and southwestern Washington is notable for its lack of butterflies, something about the village of Gray's River spoke to him on a visit thirty years ago. Ever since then he has lived in the village, which was one of the first to be established near the mouth of the Columbia River and which still feels only tenuously connected to the twenty-first century. Sky Time brings Gray's River to life by compressing those thirty years into twelve chapters, following the lives of its people, birds, butterflies - and cats- month by month through the seasons. In showing how the village has changed his life, Pyle illustrates how a special place can change anyone lucky enough to find it and highlights what is being lost in a world of accelerating speed, mobility, and sameness. Above all, Sky Time tells us that you dont have to travel far to see something new every day - if you know how to look.
The northern Adriatic Sea is transient, most recently flooded between 18,000 to 6,000 years ago following the last glacial maximum, and it will drain again with the onset of the next glacial period. Despite its youth, uniformly shallow depth, and flat sediment floor, it hosts a broad range of bottom-dwelling sea life ecologically resembling communities that have existed in the shallow sea since the Ordovician Period, some 500 million years ago. The northern Adriatic is a natural laboratory in which to test hypotheses concerning the shift from the Paleozoic prevalence of stationary suspension-feeders living on the surface of the sediment and feeding from the overlying waters to, more recently, bottom-dwelling animals living dominantly in or actively seeking temporary refuge within the sediments of the sea floor, regardless of where they feed. Across the northern Adriatic Sea there is an ecological gradient from Paleozoic-style surface-dwelling communities in the east to "modern" communities living almost exclusively within the sediments in the west. Therefore, within the relatively small area of the northern Adriatic, there is an existing gradient similar to the profound ecological change from Paleozoic to more modern marine life. During the early twentieth century, life at the bottom of the Adriatic was systematically sampled from the east to the west coasts, revealing the most common animals and their distribution. In this book Frank K. McKinney combines these findings with more recent, local studies to understand better the ecological structure of the Adriatic's floor. Specifically, he uses the predation, sediment textures and deposition rates, currents, and nutrients of northern Adriatic bottom communities to evaluate hypotheses concerning the conditions that drove surface-dwelling animals to seek long-term refuge within sea floor sediment. Though the northern Adriatic has been well studied since the advent of the marine sciences, it is not widely known by paleontologists. With this volume, McKinney illuminates what this "living laboratory" can tell us about the evolution of multicellular life on Earth.
This book deals with sedimentary sulfides which are the most abundant authigenic minerals in sediments. Special emphasis is given to the biogeochemistry that plays such a central role in the formation of sedimentary sulfides. It will be of interest to scientists in a number of disciplines, including geology, microbiology, chemistry and environmental science. The sulfur system is important to environmental scientists considering the present and future effects of pollution and anoxia. The development of the sulfur system – particularly the characteristics of ocean anoxia over the last 200 Ma – is useful in predicting the future fate of the Earth surface system as well as in understanding the past. The biochemistry and microbiology of the sulfur system are key to understanding microbial ecology and the evolution of life. - First monograph on sedimentary sulfides, covering the ancient and modern sedimentary sulfide systems - Comprehensive, integrating chemistry, microbiology, geology and environmental science - All key references are included and discussed
