"The history of Earth's early atmosphere, hydrosphere, and biosphere, from Hadean through Proterozoic time, is one of geology's enduring puzzles. Ore deposits provide important insights into this history because they contain elements and minerals that are highly sensitive to the geochemical environment in which they form. Just what these minerals tell us remains a matter of considerable debate, however. When and how did life develop, an oxygen-rich atmosphere form, and sulfate dominate the ocean? This volume contains reports on these questions from both sides of the aisle for iron and manganese formations, uranium paleoplacers and hydrothermal deposits, and exhalative sulfides and oxides."--Publisher's website.

One of the greatest mysteries in reconstructing the history of life on Earth has been the apparent absence of fossils dating back more than 550 million years. We have long known that fossils of sophisticated marine life-forms existed at the dawn of the Cambrian Period, but until recently scientists had found no traces of Precambrian fossils. The quest to find such traces began in earnest in the mid-1960s and culminated in one dramatic moment in 1993 when William Schopf identified fossilized microorganisms three and a half billion years old. This startling find opened up a vast period of time--some eighty-five percent of Earth's history--to new research and new ideas about life's beginnings. In this book, William Schopf, a pioneer of modern paleobiology, tells for the first time the exciting and fascinating story of the origins and earliest evolution of life and how that story has been unearthed. Gracefully blending his personal story of discovery with the basics needed to understand the astonishing science he describes, Schopf has produced an introduction to paleobiology for the interested reader as well as a primer for beginning students in the field. He considers such questions as how did primitive bacteria, pond scum, evolve into the complex life-forms found at the beginning of the Cambrian Period? How do scientists identify ancient microbes and what do these tiny creatures tell us about the environment of the early Earth? (And, in a related chapter, Schopf discusses his role in the controversy that swirls around recent claims of fossils in the famed meteorite from Mars.) Like all great teachers, Schopf teaches the non-specialist enough about his subject along the way that we can easily follow his descriptions of the geology, biology, and chemistry behind these discoveries. Anyone interested in the intriguing questions of the origins of life on Earth and how those origins have been discovered will find this story the best place to start.

Major Events in the History of Life, present six chapters that summarize our understanding of crucial events that shaped the development of the earth's environment and the course of biological evolution over some four billion years of geological time. The subjects are covered by acknowledged leaders in their fields span an enormous sweep of biologic history, from the formation of planet Earth and the origin of living systems to our earliest records of human activity. Several chapters present new data and new syntheses, or summarized results of new types of analysis, material not usually available in current college textbooks.

This book brings the concerned individual up-to-date on the breakthroughs and social questions emerging from biology today. Author Steve Olson draws on the latest research in a number of fields as well as the views of leading biologists, ethicists, and philosophers. He tells the story of the intricate, often frustrating, path scientists must follow to find out why we are the way we are. The volume highlights groundbreaking research being done in four of biology's most exciting fields: genetics, development, neurobiology, and evolution. In each field, the implications of this research extend far beyond basic biology, ranging from human gene therapy to cancer, from neural transplantation to the evolution of the atmosphere.

Alone in the known universe the Earth glows bright with life, a unique cosmic oasis of biodiversity which is now under threat from our own actions. The Earth is a unique as a living planet, a cosmic oasis drifting in the vastness of barren space. It is strikingly and obviously different from our nearest heavenly neighbours, the Moon, Venus and Mars, in its thin skin of biology, extending from the surface for a few kilometres into the crust, and for a few tens of kilometres into the air. But how did this remarkable abundance and diversity of life arise? How has life survived over the enormous time frame of Earth's history? And does it continue to flourish now, especially with the growing pressure for space from humans? The Cosmic Oasis examines life on Earth, from our earliest interactions with animals and plants to our absolute domination of biology. It follows our developing understanding of life's origins, its remarkable complexity, and its interactions with the air, oceans and land. It also shows how patterns of diversity across the surface of the planet evolved, and how humans are now homogenising these, degrading both biodiversity and the space in which life can exist. Within this overall trend of loss there are some remarkable examples of survival, from the beneficial relationships between the gelada monkeys and wolves of the Ethiopian highlands, and the people and brown howler monkeys of Porte Allegre in Brazil, to interactions between you and your gut microbiome. Thoughout, the authors ask what these interactions can teach us about building a better relationship with nature, and consider how we might become stewards, rather than destructive exploiters, of the life around us.

This book sets forth a set of truly controversial and astonishing theories: First, it proposes that below the surface of the earth is a biosphere of greater mass and volume than the biosphere the total sum of living things on our planet's continents and in its oceans. Second, it proposes that the inhabitants of this subterranean biosphere are not plants or animals as we know them, but heat-loving bacteria that survive on a diet consisting solely of hydrocarbons that is, natural gas and petroleum. And third and perhaps most heretically, the book advances the stunning idea that most hydrocarbons on Earth are not the byproduct of biological debris ("fossil fuels"), but were a common constituent of the materials from which the earth itself was formed some 4.5 billion years ago. The implications are astounding. The theory proposes answers to often-asked questions: Is the deep hot biosphere where life originated, and do Mars and other seemingly barren planets contain deep biospheres? Even more provocatively, is it possible that there is an enormous store of hydrocarbons upwelling from deep within the earth that can provide us with abundant supplies of gas and petroleum? However far-fetched these ideas seem, they are supported by a growing body of evidence, and by the indisputable stature and seriousness Gold brings to any scientific debate. In this book we see a brilliant and boldly original thinker, increasingly a rarity in modern science, as he develops potentially revolutionary ideas about how our world works.
