Book Description
A vivid account of a major shift in how we understand Earth, from an exceptionally talented new voice. Earth is not simply an inanimate planet on which life evolved, but rather a planet that came to life. One of humanity’s oldest beliefs is that our world is alive. Though once ridiculed by some scientists, the idea of Earth as a vast interconnected living system has gained acceptance in recent decades. We, and all living things, are more than inhabitants of Earth—we are Earth, an outgrowth of its structure and an engine of its evolution. Life and its environment have coevolved for billions of years, transforming a lump of orbiting rock into a cosmic oasis—a planet that breathes, metabolizes, and regulates its climate. Acclaimed science writer Ferris Jabr reveals a radical new vision of Earth where lush forests spew water, pollen, and bacteria to summon rain; giant animals engineer the very landscapes they roam; microbes chew rock to shape continents; and microscopic plankton, some as glittering as carved jewels, remake the air and sea. Humans are one of the most extreme examples of life transforming Earth. Through fossil fuel consumption, agriculture, and pollution, we have altered more layers of the planet in less time than any other species, pushing Earth into a crisis. But we are also uniquely able to understand and protect the planet’s wondrous ecology and self-stabilizing processes. Jabr introduces us to a diverse cast of fascinating people who have devoted themselves to this vital work. Becoming Earth is an exhilarating journey through the hidden workings of our planetary symphony—its players, its instruments, and the music of life that emerges—and an invitation to reexamine our place in it. How well we play our part will determine what kind of Earth our descendants inherit for millennia to come.

Book Description
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.

Book Description
Donald R. Prothero’s Evolution is an entertaining and rigorous history of the transitional forms and series found in the fossil record. Its engaging narrative of scientific discovery and well-grounded analysis has led to the book’s widespread adoption in courses that teach the nature and value of fossil evidence for evolution. Evolution tackles systematics and cladistics, rock dating, neo-Darwinism, and macroevolution. It includes extensive coverage of the primordial soup, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, and the transformation from early hominid to modern human. The book also details the many alleged “missing links” in the fossil record, including some of the most recent discoveries that flesh out the fossil timeline and the evolutionary process. In this second edition, Prothero describes new transitional fossils from various periods, vividly depicting such bizarre creatures as the Odontochelys, or the “turtle on the half shell”; fossil snakes with legs; and the “Frogamander,” a new example of amphibian transition. Prothero’s discussion of intelligent design arguments includes more historical examples and careful examination of the “experiments” and observations that are exploited by creationists seeking to undermine sound science education. With new perspectives, Prothero reframes creationism as a case study in denialism and pseudoscience rather than a field with its own intellectual dynamism. The first edition was hailed as an exemplary exploration of the fossil evidence for evolution, and this second edition will be welcome in the libraries of scholars, teachers, and general readers who stand up for sound science in this post-truth era.

Book Description
This book is a thorough introduction to climate science and global change. The author is a geologist who has spent much of his life investigating the climate of Earth from a time when it was warm and dinosaurs roamed the land, to today's changing climate. Bill Hay takes you on a journey to understand how the climate system works. He explores how humans are unintentionally conducting a grand uncontrolled experiment which is leading to unanticipated changes. We follow the twisting path of seemingly unrelated discoveries in physics, chemistry, biology, geology, and even mathematics to learn how they led to our present knowledge of how our planet works. He explains why the weather is becoming increasingly chaotic as our planet warms at a rate far faster than at any time in its geologic past. He speculates on possible future outcomes, and suggests that nature itself may make some unexpected course corrections. Although the book is written for the layman with little knowledge of science or mathematics, it includes information from many diverse fields to provide even those actively working in the field of climatology with a broader view of this developing drama. Experimenting on a Small Planet is a must read for anyone having more than a casual interest in global warming and climate change - one of the most important and challenging issues of our time. This new edition includes actual data from climate science into 2021. Numerous Powerpoint slides can be downloaded to allow lecturers and teachers to more effectively use the book as a basis for climate change education.

Book Description
Microfossils through Time: An Introduction is the first textbook of micropaleontology addressing undergraduate students. It presents an introduction to each group of microfossils, from bacteria to microscopical debris of vertebrates, demonstrating the broad range of study of this subdiscipline of paleontology. Not only those groups of microscopic fossils, which are traditionally considered relevant to micropaleontology, are presented (e.g., dinoflagellates, charophytes, radiolarians, spores and pollen, ostracods, chitinozoans, etc), but also others that often occur in micropaleontological samples (e.g., bivalves, echinoderms, fish debris, mammalian teeth, etc). Each of the more than forty microfossil groups are presented in an order that follows the paleontological classification, with a history of study and a variety of data on morphology, living habitats, stratigraphical distribution and their evolution, as inferred from the fossil record. The text is intended as the starting point for a new generation of textbooks that presents micropaleontology in a new structure capable of assuring an efficient transfer of expertise to the younger generations of scientists. This book will help those making their first steps in micropaleontology to develop defensible models of what microfossils are, laying the foundations for fundamental and applied studies. It introduces micropaleontology as a tool for conducting applied studies in biostratigraphy, paleoecology and for paleobathymetric estimates, basin analysis and reconstructing geological history, or related to sequence stratigraphy. It also addresses students and specialists in biology and genetics, offering a solid data base to be integrated with the other two principal components of the triad of sciences that studies the evolution of life on Earth.

Book Description
An exploration of how the Cryogenian Period, when our planet was covered in ice for millions of years, created today’s remarkable biodiversity More than half a billion years ago, our world was completely covered by glaciers, a “Snowball Earth” that persisted for millions of years. Incredibly, this unimaginable cold led to the remarkable diversification of life on earth known as the Cambrian explosion. With a geologist’s eye and a knack for storytelling, Graham Shields explores when and how such inhospitable conditions enabled animals to evolve, radiate, and diversify into our earliest ancestors. This journey navigates the wild swings between hot and cold climates, oxygenation and asphyxiation, biological radiations and extinctions, asking how such instability relates to grander forces that brought our planet to its modern state. Shields guides readers through evidence found in the Australian outback, Mongolia, Scotland, and other locales, revealing how geologists can trace glaciation, the atmosphere, oceans, mountain building, and more through the earth’s rocks, providing a comprehensive theory of how life evolved and diversified.
