Worms, protozoa, and other terrifying parasites, capable even of mind control. Author calls them the real drivers of evolution.

"Titillating and provocative essays from one of the freshest voices in science today -- Why do testicles hang the way they do? Is there an adaptive function to the female orgasm? What does it feel like to want to kill yourself? Does "free will" really exist? And why is the penis shaped like that anyway? In Why Is the Penis Shaped Like That?, the research psychologist and award-winning columnist Jesse Bering features more than thirty of his most popular essays from Scientific American and Slate, as well as two new pieces, that take readers on a bold and captivating journey through some of the most taboo issues related to evolution and human behavior. Exploring the history of cannibalism, the neurology of people who are sexually attracted to animals, the evolution of human body fluids, the science of homosexuality, and serious questions about life and death, Bering astutely covers a generous expanse of our kaleidoscope of quirks and origins. With his characteristic irreverence and trademark cheekiness, Bering leaves no topic unturned or curiosity unexamined, and he does it all with an audaciously original voice. Whether you are interested in the psychological history behind the many facets of sexual desire or the evolutionary patterns that have dictated our current mystique and phallic physique, Why Is the Penis Shaped Like That? is bound to create lively discussion and debate for years to come"--

Finalist for the Los Angeles Times Book Prize From the man who Oliver Sacks hailed as “one of the best scientist/writers of our time,” a collection of sharply observed, uproariously funny essays on the biology of human culture and behavior. In the tradition of Stephen Jay Gould and Oliver Sacks, Robert Sapolsky offers a sparkling and erudite collection of essays about science, the world, and our relation to both. “The Trouble with Testosterone” explores the influence of that notorious hormone on male aggression. “Curious George’s Pharmacy” reexamines recent exciting claims that wild primates know how to medicate themselves with forest plants. “Junk Food Monkeys” relates the adventures of a troop of baboons who stumble upon a tourist garbage dump. And “Circling the Blanket for God” examines the neurobiological roots underlying religious belief. Drawing on his career as an evolutionary biologist and neurobiologist, Robert Sapolsky writes about the natural world vividly and insightfully. With candor, humor, and rich observations, these essays marry cutting-edge science with humanity, illuminating the interconnectedness of the world’s inhabitants with skill and flair.

Humanity has always been intrigued by the timeless question: Where did we come from? In 1974, the discovery of the fossilised bones of a three-million-year-old female dubbed 'Lucy' captured the world's attention. This nearly complete skeleton of an early human ancestor not only triggered widespread interest in our human origins but also prompted a thorough re-evaluation of established scientific doctrines. Today, hardly a month goes by without news of significant discoveries that are changing our understanding of human origins at what seems like the speed of lightning. But what does all this new knowledge about our species mean? That's exactly what acclaimed science writer Carl Zimmer tackles in this accessible, up-to-the-minute guide to human origins. Zimmer offers an entertaining and illuminating journey through our ancestry - beginning sixty-five million years ago with the first primates and ending today, as we enter a new phase of evolution. From ancient fossils unearthed in the Sahara Desert to the analysis of DNA by robots at the National Human Genome Research Institute in suburban Maryland, Zimmer weaves together the varied clues about our human ancestry in an entertaining, informative and highly readable volume that will appeal to expert and general reader alike.

How do we understand the world? While some look to the heavens for intelligent design, others argue that it is determined by information encoded in DNA. Science serves as an important activity for uncovering the processes and operations of nature, but it is also immersed in a social context where ideology influences the questions we ask and how we approach the material world. Biology Under the Influence: Dialectical Essays on the Coevolution of Nature and Society breaks from the confirms of determinism, offering a dialectical analysis for comprehending a dynamic social and natural world. In Biology Under the Influence , Richard Lewontin and Richard Levins provide a devastating critique of genetic determinism and reductionism within science while exploring a broad range of issues including the nature of science, biology, evolution, the environment, pubic health, and dialectics, They dismantle the ideology that attempts to naturalize social inequalities, unveil the alienation of science and nature, and illustrate how a dialectical position serves as a basis for grappling with historical developments and a world characterized by change. Biology Under the Influence brings together the illuminating essays of two prominent scientists who work to demystify and empower the public's understanding of science and nature.

Groundbreaking research over the last 10 years has given rise to the hologenome concept of evolution. This concept posits that the holobiont (host plus all of its associated microorganisms) and its hologenome (sum of the genetic information of the host and its symbiotic microorganisms), acting in concert, function as a unique biological entity and therefore as a level of selection in evolution. All animals and plants harbor abundant and diverse microbiota, including viruses. Often the amount of symbiotic microorganisms and their combined genetic information far exceed that of their host. The microbiota with its microbiome, together with the host genome, can be transmitted from one generation to the next and thus propagate the unique properties of the holobiont. The microbial symbionts and the host interact in a cooperative way that affects the health of the holobiont within its environment. Beneficial microbiota protects against pathogens, provides essential nutrients, catabolizes complex polysaccharides, renders harmful chemicals inert, and contributes to the performance of the immune system. In humans and animals, the microbiota also plays a role in behavior. The sum of these cooperative interactions characterizes the holobiont as a unique biological entity. Genetic variation in the hologenome can be brought about by changes in either the host genome or the microbial population genomes (microbiome). Evolution by cooperation can occur by amplifying existing microbes, gaining novel microbiota and by acquiring microbial and viral genes. Under environmental stress, the microbiome can change more rapidly and in response to more processes than the host organism alone and thus influences the evolution of the holobiont. Prebiotics, probiotics, synbiotics and phage therapy are discussed as applied aspects of the hologenome concept.

This enticing collection is as devoted to the profound power of figures of speech as any oration of old Hellas. Metaphor reigns as we encounter the identification of our Earth as a Single, integrative organism, a tale told in image and passion. The discoveries and conjectures upon which this grand view rest are here as well. I have enjoyed these two dozen pieces hugely. No family tree of animal life but must somewhere disclose a cousinly infolding. We are compact of life past, and the looped handing down is more complex than the Mendel-Morgan dance of chromosomes and genes. That dance is essential, certainly, but it is the vital editing of an epic and many-rooted work, a book more like the Bible than like one great artists Remembrance of Things Past. We follow a few old shelves of bound DNA, not just a single book. Our major biochemical package for oxidative metabolism was de scribed in a small DNA manual, somehow engulfed to become an or ganelle within a lucky ancient ancestral anaerobe, and passed ever since viii FOREWORD from mother to offspring outside of the chromosome shuffie. The sperm do carry half the compact genetic message of the human DNA, but they are too small to transfer this equally essential symbiotic one that comes down from the mothers, within roomy egg after roomy egg.

The Advances in Cancer Research series provides invaluable information on the exciting and fast-moving field of cancer research. This volume presents outstanding and original reviews on a variety of topics.

""How many creatures walking on this earth / Have their first being in another form?" the Roman poet Ovid asked two thousand years ago. He could not have known the full extent of the truth: Today, biologists estimate a stunning three-quarters of all animal species on earth undergo some form of metamorphosis. But why do tadpoles transform into frogs, caterpillars into butterflies, elvers into eels, immortal jellyfish from sea sprigs to medusae and back again, growing younger and younger in frigid ocean depths? Why must creatures go through massive destruction and remodeling to become who they are? Tracing a path from Aristotle--who rejected the possibility of metamorphosis--to Darwin to today, historian of science Oren Harman explores that central mystery. Metamorphosis, however, isn't just a biological puzzle: It takes us to the very heart of questions of being and identity, whatever kind of change we may undergo. Metamorphosis is a new classic of natural history: a book that, by unveiling a mystery of nature, causes us to relearn ourselves"--Publisher's description.

Lynn Margulis, one of the most original and perceptive scientific thinkers of our time, and the writer Dorion Sagan here present a selection from their many essays published in the last decade and a half. This collection includes an extraordinary memoir of Margulis' encounter with J. Robert Oppenheimer as well as provocative ideas on Gaia theory, symbiosis, individuality, and the way scientific research is conducted today.

This book is the first devoted to modern biology s innovators and iconoclasts: men and women who challenged prevailing notions in their fields. Some of these scientists were Nobel Prize winners, some were considered cranks or gadflies, some were in fact wrong. The stories of these stubborn dissenters are individually fascinating. Taken together, they provide unparalleled insights into the role of dissent and controversy in science and especially the growth of biological thought over the past century. Each of the book s nineteen specially commissioned chapters offers a detailed portrait of the intellectual rebellion of a particular scientist working in a major area of biology--genetics, evolution, embryology, ecology, biochemistry, neurobiology, and virology as well as others. An introduction by the volume s editors and an epilogue by R. C. Lewontin draw connections among the case studies and illuminate the nonconforming scientist s crucial function of disturbing the comfort of those in the majority. By focusing on the dynamics and impact of dissent rather than on winners who are credited with scientific advances, the book presents a refreshingly original perspective on the history of the life sciences. Scientists featured in this volume: Alfred Russel Wallace Hans Driesch Wilhelm Johannsen Raymond Arthur Dart C. D. Darlington Richard Goldschmidt Barbara McClintock Oswald T. Avery Roger Sperry Leon Croizat Vero Copner Wynne-Edwards Peter Mitchell Howard Temin Motoo Kimura William D. Hamilton Carl Woese Stephen Jay Gould Thelma Rowell Daniel S. Simberloff "

"Is life different from the non-living? If so, how? And how, in that case, does biology, as the study of living things, differ from other sciences? These questions lie at the heart of The Philosophy of Biology, and are traced through an exploration of episodes in the history of biology and philosophy. The book begins with Aristotle, then moves on to Descartes, comparing his position with that of Harvey. From the eighteenth century, the authors consider Buffon and Kant. From the nineteenth century, the authors examine the Cuvier-Geoffroy debate, pre-Darwinian geology and natural theology, Darwin, and the transition from Darwin to the revival of Mendelism. Two chapters on the twentieth century deal with the Modern Evolutionary Synthesis and such questions as the species problem, the reducibility or otherwise of biology to physics and chemistry, and the problem of biological explanation in terms of function and teleology. The final chapters reflect on the question of human nature and the implications of the philosophy of biology for the philosophy of science in general."--Jacket

The significance of human individuality is such that each human functions as a unique "molecular" unit of the mass of humanity. Understanding the natural basis for the uniqueness of the individual has long been an objective. The possibilities have been analyzed by Julian Huxley, by A. E. Needham, by Roger Williams, and by others. With his books Biochemical Individuality and Free and Unequal, Roger Williams has done as much as anyone to focus atten tion on this complex of questions. Although scheduled to partici pate in this program, Roger Williams* was unable to attend due to illness. He asked, however, that a quotation be included in the proceedings. This quotation from Chraka is presented early in this book. While metabolic bases for individuality have received a con siderable investigation and discussion by Williams and others, the case for underlying determinants and derivative consequences have not been examined as fully. The specificities that abound in our living world can be traced to the manner in which molecules fit with each other. While numerous studies having other objectives can be cited in support of molecularly based specificities, a few of the leaders in the development of the understanding of physical aspects of biological information present here some of their latest inferences. Several of the participants discuss some of the conse quences at higher levels. Examination of the fascinating cases of reunited identical twins are seen as providing a capstone to the hierarchical treatment.

This unique book is the first of its kind to explore the diversity of interactions between insects and birds. A group of international experts enthusiastically agreed to contribute to the four sections of the book following the success of an Entomological Club Conference on Insect and Bird Interactions. The first section covers population management issues, discussing effects on birds highly relevant to the planting of large areas of GM crops, new opportunities for increasing biodiversity in farming landscapes, and the novel aspect of managing insects by exploiting birds as biological control agents. This is followed by a section discussing the effects of insecticides on bird populations, and includes a contribution from the RSPB, as well as a re-appraisal of the effects of DDT on raptors. Next, the foraging behaviour of birds on insects is discussed, with chapters also on ‘warning’ coloration in insects and learning by birds. The first chapter in this section is unusual in having been written by an ophthalmologist and covers colour vision in birds, more specifically ultraviolet vision in relation to insect coloration. Finally, the authors look at insects that are parasites of birds or feed on the detritus in nests, and review the ecology and evolution of the co-adaptation of insect ectoparasites with birds. Insect and Bird Interactions is unparalleled in scope and coverage and will be of interest to entomologists, ornithologists, and ecologists alike.
