Over the last half billion years, there have been five major mass extinctions, when the diversity of life on Earth suddenly and dramatically contracted. Scientists are currently monitoring the sixth extinction, predicted to be the most devastating since the asteroid impact that wiped out the dinosaurs. This time around the cataclysm is us. In this book the author tells us why and how human beings have altered life on the planet in a way no species has before. She provides a moving account of the disappearances of various species occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up to Lyell and Darwin, and through the present day. The sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human. -- Publisher description.

"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"--

"Totem and Taboo" is a collection of four essays by Sigmund Freud that were published together in German in 1913. Freud sought to apply his theories of psychoanalysis to the study of anthropology and early human history. The four essays cover a wide range of topics. In "The Horror of Incest", Freud examines the varied and common rules in primitive cultures that limit contact between members of the same family. In "Taboo and Emotional Ambivalence," Freud posits that primitive cultures and their attitudes about magical objects are similar to the behavior of people with neurotic psychological conditions in the modern world. In "Animism, Magic and the Omnipotence of Thought," Freud draws comparisons between the primitive belief in magic and magical animals to obsessive and compulsive disorders. Finally, in "The Return of Totemism in Childhood," Freud, influenced by one of Charles Darwin's theories about the male-dominated arrangement of early human societies, looks for parallels with his own Oedipus complex theory in the structure of primitive cultures. A classic and influential work of early psychoanalysis, "Totem and Taboo" is an important read for students of both psychology and social anthropology.

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.

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.

Everything about our existence-movement and memory, imagination and reproduction, birth, and ultimately death-is governed by our cells. They are the basis of all life in the universe, from bacteria to the most complex animals. In the tradition of the classic Lives of a Cell, but with the benefit of the latest research, Lewis Wolpert demonstrates how human life grows from a single cell into a body, an incredibly complex society of billions of cells. Wolpert goes on to examine the science behind topics that are much discussed but rarely understood stem-cell research, cloning, DNA, cancer and explains how all life on earth evolved from just one cell. Lively and passionate, this is an accessible guide to understanding the human body and life itself."

Philosophers have not taken the evolution of human beings seriously enough. If they did, argues Peter Munz, many long standing philosophical problems would be resolved. One of philosophical concequences of biology is that all the knowledge produced in evolution is a priori , i.e., established hypothetically by chance mutation and selective retention, not by observation and intelligent induction. For organisms as embodied theories, selection is natural and for theories as disembodied organisms, it is artificial. Following Popper, the growth of knowledge is seen to be continuous from the amoeba to Einstein'. Philosophical Darwinism throws a whole new light on many contemporary debates. It has damaging implications for cognitive science and artificial intelligence, and questions attempts from within biology to reduce mental events to neural processes. More importantly, it provides a rational postmodern alternative to what the author argues are the unreasonable postmodern fashions of Kuhn, Lyotard and Rorty.

Timely and unrivalled, this first work to categorize and systematically cover all recently identified receptors in the human genome is all set to become the gold standard in the field of receptor genetics and physiology. In three handy volumes, this comprehensive guide adopts an innovative approach, where, in the first part, each receptor family is discussed individually, based on the latest evidence. In the second part, the knowledge is integrated into concepts and overviews of common themes in present-day receptor research.While serving as a central resource for many disciplines, including biochemistry, molecular genetics and physiology, this reference will be equally welcomed by drug developers and cancer researchers.

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.

A fascinating tribute to the forefathers of two of today’s most exciting scientific fields Thanks to Max Delbruck and George Gamow, today we have mapped the human genome and understand the ramifications of the Big Bang. In his characteristically inviting and elegant style, Gino Segre brings to life the story of these two great scientists and their long friendship and offers an accessible inside look the people behind the scenes of science—the collaboration and competition, the quirks and failures, the role of intuition and luck, and the sense of wonder and curiosity that keeps these extraordinary minds going.

Rapid advances in the physical and biological sciences and in related technologies have brought about equally farreaching changes in mathematical research. Focusing on control theory, invariant imbedding, dynamic programming, and quasilinearization, Mr. Bellman explores with ease and clarity the mathematical research problems arising from scientific questions in engineering, physics, biology, and medicine. Special attention is paid in these essays to the use of the digital computer in obtaining the numerical solution of numerical problems, its influence in the formulation of new and old scientific problems in new terms, and to some of the effects of the computer revolution on educational and social systems. The new opportunities for mathematical research presage, Bellman concludes, a renaissance of mathematics in human affairs by involving it closely in the problems of society.

These companion volumes, long out of print, are now presented together for the first time so that the reader may better grasp their essential unity. In Ether, God and Devil, Wilhelm Reich describes the process of functional thinking and reveals how the inner logic of this objective thought technique led him to the discovery of cosmic orgone energy. In Cosmic Superimposition , Reich steps beyond the character structure of man to an understanding of how man is rooted in nature. The super-imposition of two orgone-energy systems which is demonstrable in the genital embrace is revealed as a common functioning principal that exists in all of nature. Concluding this work, Reich returns to the human sphere "to ponder about the greatest riddle of all: the ability of man to think, and by mere thinking to know what nature is and how it works."
