Probably most or even all of the above. The story of our home planet and the organisms spread across its surface is far more spectacular than any Hollywood blockbuster, filled with enough plot twists to rival a bestselling thriller. But only recently have we begun to piece together the whole mystery into a coherent narrative. Drawing on his decades of field research and up-to-the-minute understanding of the latest science, renowned geologist Andrew H. Knoll delivers a rigorous yet accessible biography of Earth, charting our home planet's epic 4.6 billion-year story. Placing twenty first-century climate change in deep context, A Brief History of Earth is an indispensable look at where we’ve been and where we’re going.Features original illustrations depicting Earth history and nearly 50 figures (maps, tables, photographs, graphs).

    Beginning with the Big Bang, David Christian views the interaction of the natural world with the more recent arrivals in flora and fauna, including human beings.Cosmology, geology, archeology, and population and environmental studies—all figure in David Christian's account, which is an ambitious overview of the emerging field of "Big History." Maps of Time opens with the origins of the universe, the stars and the galaxies, the sun and the solar system, including the earth, and conducts readers through the evolution of the planet before human habitation. It surveys the development of human society from the Paleolithic era through the transition to agriculture, the emergence of cities and states, and the birth of the modern, industrial period right up to intimations of possible futures. Sweeping in scope, finely focused in its minute detail, this riveting account of the known world, from the inception of space-time to the prospects of global warming, lays the groundwork for world history—and Big History—true as never before to its name.

    With extensive treatment of the heart of epidemiology-from study designs to descriptive epidemiology to quantitative measures-this reader-friendly text is accessible and interesting to a wide range of beginning students in all health-related disciplines. A unique focus is given to real-world applications of epidemiology and the development of skills that students can apply in subsequent course work and in the field. The text is also accompanied by a complete package of instructor and student resources available through a companion Web site.

    Baboons live in groups of up to 150, including a handful of males and eight or nine matrilineal families of females. Such numbers force baboons to form a complicated mix of short-term bonds for mating and longer-term friendships based on careful calculations of status and individual need.           But Baboon Metaphysics is concerned with much more than just baboons’ social organization—Cheney and Seyfarth aim to fully comprehend the intelligence that underlies it. Using innovative field experiments, the authors learn that for baboons, just as for humans, family and friends hold the key to mitigating the ill effects of grief, stress, and anxiety.           Written with a scientist’s precision and a nature-lover’s eye, Baboon Metaphysics gives us an unprecedented and compelling glimpse into the mind of another species.  “The vivid narrative is like a bush detective story.”—Steven Poole, Guardian “Baboon Metaphysics is a distillation of a big chunk of academic lives. . . . It is exactly what such a book should be—full of imaginative experiments, meticulous scholarship, limpid literary style, and above all, truly important questions.”—Alison Jolly, Science “Cheney and Seyfarth found that for a baboon to get on in life involves a complicated blend of short-term relationships, friendships, and careful status calculations. . . . Needless to say, the ensuing political machinations and convenient romantic dalliances in the quest to become numero uno rival the bard himself.”—Science News “Cheney and Seyfarth’s enthusiasm is obvious, and their knowledge is vast and expressed with great clarity. All this makes Baboon Metaphysics a captivating read. It will get you thinking—and maybe spur you to travel to Africa to see it all for yourself.”—Asif A. Ghazanfar, Nature “Through ingenious playback experiments . . . Cheney and Seyfarth have worked out many aspects of what baboons used their minds for, along with their limitations. Reading a baboon’s mind affords an excellent grasp of the dynamics of baboon society. But more than that, it bears on the evolution of the human mind and the nature of human existence.”—Nicholas Wade, New York Times

    Suppose, instead of thinking about organisms using genes to reproduce themselves, as we had since Mendel's work was rediscovered, we turn it around and imagine that "our" genes build and maintain us in order to make more genes. That simple reversal seems to answer many puzzlers which had stumped scientists for years, and we haven't thought of evolution in the same way since. Drawing fascinating examples from every field of biology, he paved the way for a serious re-evaluation of evolution. He also introduced the concept of self-reproducing ideas, or memes, which (seemingly) use humans exclusively for their propagation. If we are puppets, he says, at least we can try to understand our strings.

    Evolutionary Dynamics is concerned with these equations of life. In this book, Martin A. Nowak draws on the languages of biology and mathematics to outline the mathematical principles according to which life evolves. His work introduces readers to the powerful yet simple laws that govern the evolution of living systems, no matter how complicated they might seem. Evolution has become a mathematical theory, Nowak suggests, and any idea of an evolutionary process or mechanism should be studied in the context of the mathematical equations of evolutionary dynamics. His book presents a range of analytical tools that can be used to this end: fitness landscapes, mutation matrices, genomic sequence space, random drift, quasispecies, replicators, the Prisoner's Dilemma, games in finite and infinite populations, evolutionary graph theory, games on grids, evolutionary kaleidoscopes, fractals, and spatial chaos. Nowak then shows how evolutionary dynamics applies to critical real-world problems, including the progression of viral diseases such as AIDS, the virulence of infectious agents, the unpredictable mutations that lead to cancer, the evolution of altruism, and even the evolution of human language. His book makes a clear and compelling case for understanding every living system--and everything that arises as a consequence of living systems--in terms of evolutionary dynamics.

    But it was not until many years after veterinary school, when she was transporting a chimpanzee named Pierre away from a biomedical facility as part of her job as a conservation advocate in Cameroon, that Dr. Speede discovered her true calling. She began to search for land for a forest sanctuary for captive chimpanzees that were held on chains and in small cages at local hotels.Dr. Speede eventually founded the Sanaga-Yong Chimpanzee Rescue Center, a forested home for orphans of the illegal ape meat trade. One chim- panzee, Dorothy, was rescued by Dr. Speede and her colleagues from a bleak existence imprisoned on a chain and forged a deep friendship with her. Dr. Speede explains how chimpanzees, like humans, are capable of a broad spectrum of emotional behaviors—both hateful and loving. Dr. Speede also candidly reveals her own struggles as a stranger in a foreign culture trying to adjust to rural African village life. And she admits that unlike Dorothy, she was not always kind, gentle, and forgiving.Dorothy died of old age at the sanctuary, and a photograph of Dorothy's funeral, in which Dr. Speede cradled Dorothy's head while her family of chimpanzees mournfully viewed her body, went viral after being published in National Geographic. The world was surprised at the depth of the chimps' grief at the loss of their friend, but Dr. Speede was not. Through the chimps, she had come to understand the meaning of love, loyalty, and true connection.While this is a compelling story about the emotional complexity of the chimpanzees she rescued and befriended, it is also Dr. Speede's story. Major events in her personal life, including love affairs, dangerous run-ins with criminals, and the birth of her daughter, unfold as the development of her primate rescue center runs parallel to her own development. Ultimately, Kindred Beings is a story of profound resilience, of both the apes and the woman who loved them.

    Our bodies are a quirky mix of new and old, with strokes of genius alongside glitches and imperfections which are all inherited from distant ancestors. Our development and evolutionary past explains why, as embryos, we have what look like gills, and as adults we suffer from back pain.This is a tale of discovery, not only exploring why and how we have developed as we have, but also looking at the history of our anatomical understanding. It combines the remarkable skills and qualifications Alice Roberts has as a doctor, anatomist, osteoarchaeologist and writer. Above all, she has a rare ability to make science accessible, relevant and interesting to mainstream audiences and readers.

    An exhilarating account of Sapolsky’s twenty-one-year study of a troop of rambunctious baboons in Kenya, A Primate’s Memoir interweaves serious scientific observations with wry commentary about the challenges and pleasures of living in the wilds of the Serengeti — for man and beast alike. Over two decades, Sapolsky survives culinary atrocities, gunpoint encounters, and a surreal kidnapping, while witnessing the encroachment of the tourist mentality on the farthest vestiges of unspoiled Africa. As he conducts unprecedented physiological research on wild primates, he becomes evermore enamored of his subjects — unique and compelling characters in their own right — and he returns to them summer after summer, until tragedy finally prevents him.By turns hilarious and poignant, A Primate’s Memoir is a magnum opus from one of our foremost science writers.

    

    An Introduction to Meteorology (13th Edition)

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    In this new Seventh Edition of his perennially successful social research text, author Russell K. Schutt continues to make research come alive through stories that illustrate the methods presented in each chapter, and hands-on exercises that help students learn by doing. Investigating the Social World helps readers understand research methods as an integrated whole, appreciate the value of both qualitative and quantitative methodologies, and understand the need to make ethical research decisions. New to this Edition: * upgraded coverage of research methods to include the spread of cell phones and the use of the Internet, including expanded coverage of Web surveys * larger page size in full color allows for better display of pedagogical features * new 'Research in the News' boxes included within chapters * more international examples * expanded statistics coverage now includes more coverage of inferenctial statistics and regression analysi

    Therefore, while students still learn the skills necessary to design research, the book emphasizes the quantitative reasoning skills students need to become systematic and critical consumers of information. Examples from a variety of sources capture students' interest, and the innovative pedagogical framework ensures that students will retain and be able to apply what they learn.

    As swiftly as it came, it disappeared, leaving no trace. Over the four decades since, Ebola has emerged sporadically, each time to devastating effect. It can kill up to 90 percent of its victims. In between these outbreaks, it is untraceable, hiding deep in the jungle. The search is on to find Ebola’s elusive host animal. And until we find it, Ebola will continue to strike. Acclaimed science writer and explorer David Quammen first came near the virus while he was traveling in the jungles of Gabon, accompanied by local men whose village had been devastated by a recent outbreak. Here he tells the story of Ebola—its past, present, and its unknowable future.Extracted from Spillover by David Quammen, updated and with additional material.
