The quest to pinpoint the age of the Earth is nearly as old as humanity itself. For most of history, people trusted mythology or religion to provide the answer, even though nature abounds with clues to the past of the Earth and the stars. In A Natural History of Time, geophysicist Pascal Richet tells the fascinating story of how scientists and philosophers examined those clues and from them built a chronological scale that has made it possible to reconstruct the history of nature itself.
Richet begins his story with mythological traditions, which were heavily influenced by the seasons and almost uniformly viewed time cyclically. The linear history promulgated by Judaism, with its story of creation, was an exception, and it was that tradition that drove early Christian attempts to date the Earth. For instance, in 169 CE, the bishop of Antioch, for instance declared that the world had been in existence for “5,698 years and the odd months and days.”
Until the mid-eighteenth century, such natural timescales derived from biblical chronologies prevailed, but, Richet demonstrates, with the Scientific Revolution geological and astronomical evidence for much longer timescales began to accumulate. Fossils and the developing science of geology provided compelling evidence for periods of millions and millions of years—a scale that even scientists had difficulty grasping. By the end of the twentieth century, new tools such as radiometric dating had demonstrated that the solar system is four and a half billion years old, and the universe itself about twice that, though controversial questions remain.
The quest for time is a story of ingenuity and determination, and like a geologist, Pascal Richet carefully peels back the strata of that history, giving us a chance to marvel at each layer and truly appreciate how far our knowledge—and our planet—have come.
Nature Journal is an innovative presentation of the best columns and photographs from L. J. Davenport’s popular column in Alabama Heritage magazine. Readers of the magazine have come to relish his artful and often witty descriptions of common species encountered in the Alabama outdoors. But Nature Journal is designed to be much more than a mere collection of entertaining essays; it is also an educational tool—a means of instructing and encouraging readers in the art of keeping a nature journal for themselves.
Each of the 25 chapters is a self-contained lesson in close observation of species morphology, behavior, and habitat; research in the literature; nondestructive capture of the subject by photography or drawing; and written description of the total observed natural phenomenon. At the end of each account, stimulating questions and gentle directives guide the reader into making his or her own observations and recordings.
This book is intended for broad nature-study use in Alabama and throughout the southeast by the general reader and nature enthusiast alike, as well as visitors to museums and outdoor centers, and students of nature and nature writing at the high school and college levels. Beautifully designed to look like a personal journal, it is a perfect gift and treasured keepsake for all lovers of the natural world.

The rapid growth of the American environmental movement in recent decades obscures the fact that long before the first Earth Day and the passage of the Endangered Species Act, naturalists and concerned citizens recognized—and worried about—the problem of human-caused extinction.
As Mark V. Barrow reveals in Nature’s Ghosts, the threat of species loss has haunted Americans since the early days of the republic. From Thomas Jefferson’s day—when the fossil remains of such fantastic lost animals as the mastodon and the woolly mammoth were first reconstructed—through the pioneering conservation efforts of early naturalists like John James Audubon and John Muir, Barrow shows how Americans came to understand that it was not only possible for entire species to die out, but that humans themselves could be responsible for their extinction. With the destruction of the passenger pigeon and the precipitous decline of the bison, professional scientists and wildlife enthusiasts alike began to understand that even very common species were not safe from the juggernaut of modern, industrial society. That realization spawned public education and legislative campaigns that laid the foundation for the modern environmental movement and the preservation of such iconic creatures as the bald eagle, the California condor, and the whooping crane.
A sweeping, beautifully illustrated historical narrative that unites the fascinating stories of endangered animals and the dedicated individuals who have studied and struggled to protect them, Nature’s Ghosts offers an unprecedented view of what we’ve lost—and a stark reminder of the hard work of preservation still ahead.
The Faustian bargain—in which an individual or group collaborates with an evil entity in order to obtain knowledge, power, or material gain—is perhaps best exemplified by the alliance between world-renowned human geneticists and the Nazi state. Under the swastika, German scientists descended into the moral abyss, perpetrating heinous medical crimes at Auschwitz and at euthanasia hospitals. But why did biomedical researchers accept such a bargain?
The Nazi Symbiosis offers a nuanced account of the myriad ways human heredity and Nazi politics reinforced each other before and during the Third Reich. Exploring the ethical and professional consequences for the scientists involved as well as the political ramifications for Nazi racial policies, Sheila Faith Weiss places genetics and eugenics in their larger international context. In questioning whether the motives that propelled German geneticists were different from the compromises that researchers from other countries and eras face, Weiss extends her argument into our modern moment, as we confront the promises and perils of genomic medicine today.
In this accessible analysis, a philosopher and a science educator look at biological theory and society through a synthesis of mechanistic and organicist points of view to best understand the complexity of life and biological systems.
The search for a unified framework for biology is as old as Plato’s musings on natural order, which suggested that the universe itself is alive. But in the twentieth century, under the influence of genetics and microbiology, such organicist positions were largely set aside in favor of mechanical reductionism, by which life is explained by the movement of its parts. But can organisms truly be understood in mechanical terms, or do we need to view life from the perspective of whole organisms to make sense of biological complexity?
The New Biology argues for the validity of holistic treatments from the perspectives of philosophy, history, and biology and outlines the largely unrecognized undercurrent of organicism that has persisted. Mechanistic biology has been invaluable in understanding a range of biological issues, but Michael Reiss and Michael Ruse contend that reductionism alone cannot answer all our questions about life. Whether we are considering human health, ecology, or the relationship between sex and gender, we need to draw from both organicist and mechanistic frameworks.
It’s not always a matter of combining organicist and mechanistic perspectives, Reiss and Ruse argue. There is scope for a range of ways of understanding the complexity of life and biological systems. Organicist and mechanistic approaches are not simply hypotheses to be confirmed or refuted, but rather operate as metaphors for describing a universe of sublime intricacy.
“A name is forever, or at least as long as taxonomy continues,” Barry Bolton writes, and here are all the names, antique and modern, of all the ants that are or ever were—from the arctic to the tropical, the fossilized to the living, the mislabeled to the newly christened members of the family Formicidae. For every name that has ever been applied to ants, the book supplies a history and an account of current usage, together with a fully documented indication of the present-day classification. Its comprehensive bibliography provides references to original description, synonymy, homonymy, changes in rank, status, and availability, and alterations in generic status.
Organized by family group, genus group, and species group, this meticulously detailed but easily used volume is the ultimate resource for myrmecology. Along with Bolton’s Identification Guide to the Ant Genera of the World, it will be the essential reference for anyone, expert or amateur, with an interest in ants.
Noise, as we usually think of it, is background sound that interferes with our ability to hear more interesting sounds. In general terms, though, it is anything that interferes with the reception of signals of any sort. It includes extraneous energy in the environment, degradation of signals in transit, and spontaneous random activity in receivers and signalers. Whatever the cause, the consequence of noise is error by receivers, and these errors are the key to understanding how noise shapes the evolution of communication.
Noise Matters breaks new ground in the scientific understanding of how communication evolves in the presence of noise. Combining insights of signal detection theory with evidence from decades of his own original research, Haven Wiley explains the profound effects of noise on the evolution of communication. The coevolution of signalers and receivers does not result in ideal, noise-free communication, Wiley finds. Instead, signalers and receivers evolve to a joint equilibrium in which communication is effective but never error-free. Noise is inescapable in the evolution of communication.
Wiley’s comprehensive approach considers communication on many different levels of biological organization, from cells to individual organisms, including humans. Social interactions, such as honesty, mate choice, and cooperation, are reassessed in the light of noisy communication. The final sections demonstrate that noise even affects how we think about human language, science, subjectivity, and freedom. Noise Matters thus contributes to understanding the behavior of animals, including ourselves.
Recent polls suggest that fewer than 40 percent of Americans believe in Darwin’s theory of evolution, despite it being one of science’s best-established findings. More and more parents are refusing to vaccinate their children for fear it causes autism, though this link can been consistently disproved. And about 40 percent of Americans believe that the threat of global warming is exaggerated, despite near consensus in the scientific community that manmade climate change is real.
Why do people believe bunk? And what causes them to embrace such pseudoscientific beliefs and practices? Noted skeptic Massimo Pigliucci sets out to separate the fact from the fantasy in this entertaining exploration of the nature of science, the borderlands of fringe science, and—borrowing a famous phrase from philosopher Jeremy Bentham—the nonsense on stilts. Presenting case studies on a number of controversial topics, Pigliucci cuts through the ambiguity surrounding science to look more closely at how science is conducted, how it is disseminated, how it is interpreted, and what it means to our society. The result is in many ways a “taxonomy of bunk” that explores the intersection of science and culture at large.
No one—not the public intellectuals in the culture wars between defenders and detractors of science nor the believers of pseudoscience themselves—is spared Pigliucci’s incisive analysis. In the end, Nonsense on Stilts is a timely reminder of the need to maintain a line between expertise and assumption. Broad in scope and implication, it is also ultimately a captivating guide for the intelligent citizen who wishes to make up her own mind while navigating the perilous debates that will affect the future of our planet.
Daniel Otte offers a comprehensive taxonomic treatise on all known species of grasshoppers from the Gulf of Panama to Alaska. Grasshoppers are a dominant form of life in most terrestrial habitats. The abundance of grasshoppers and the ease of obtaining them have brought about their extensive use in a wide variety of biological studies. It is probably fair to say that grasshoppers are biologically better understood than any equivalent group of insects. They were used in pioneering studies in genetics and are increasingly being used to test evolutionary, ecological, and physiological theories. Unfortunately, much of this work is still based on a poor classification, and many studies are hindered by difficulties which arise in identifying the species.
Now for the first time scientists are provided with:
– Illustrated keys and lists for distinguishing genera and species;
– Information on distributional limits, habitat preference, ecology, behavior, and life cycle;
– A list of pertinent references;
– Point distribution maps;
– A taxonomic index as well as a history of name changes.
But the book’s most spectacular feature is the author’s detailed drawings of all species in full color. The North American Grasshoppers will be especially useful to scientists in agriculture, environmental assessment, biogeography, grassland ecology, and insect taxonomy, and will also appeal to amateur naturalists. Undoubtedly, it will long stand as a definitive reference in its field.
