Book Description
The story of human evolution has been told hundreds of times, each time with a focus that seems most informative of the teller. No matter how it is told the primary characters are rarely mothers and infants. Darwin argued survival, but today we know that reproduction is what evolution is all about. Centering on this, Trevathan focuses on birth, which gives the study of human evolution a crucial new dimension.Unique among mammals, humans are bipedal. The evolution of bipedalism required fundamental changes in the pelvis and resulted in a narrow birth canal. Humans are also large-brained animals, which means that birth is much more challenging for our species than for most other animals. The result of this mismatch of large head and narrow pelvis is that women are highly dependent on assistance at birth and their babies are born in an unusually undeveloped state when the brain is still small. Human Birth discusses how the birth process has evolved and ways in which human birth differs from birth in all other mammals.Human Birth is also concerned with mother-infant interaction immediately after birth. While working as a midwife trainee, Trevathan carefully documented the births of more than one hundred women and recorded maternal and infant behaviors during the first hour after birth. She suggests ways in which the interactions served not only to enhance mother-infant bonding, but also to ensure survival in the evolutionary past. With clarity and compelling logic Trevathan argues that modern birth practices often fail to meet evolved needs of women and infants and suggests changes that could lead to better birth experiences. This paperback edition includes a new introduction by the author.

Book Description
An anthropologist and an anatomist have combined their skills in this book to provide students and research workers with the essentials of anatomy and the means to apply these to investigations into hominid form and function. Using basic principles and relevant bones, conclusions can be reached regarding the probable musculature, stance, brain size, age, weight, and sex of a particular fossil specimen. The sort of deductions which are possible are illustrated by reference back to contemporary apes and humans, and a coherent picture of the history of hominid evolution appears. Written in a clear and concise style and beautifully illustrated, An Introduction to Human Evolutionary Anatomy is a basic reference for all concerned with human evolution as well as a valuable companion to both laboratory practical sessions and new research using fossil skeletons.

Book Description
The contents of this book are based almost exclusively on purely anatomical researches. These were stimulated by questions posed in clinical practice. The results are directed to practicing surgeons. Their chronological sequence leads to a step by step development of theoretical bases and to a progressive rejection of old conceptions. Especially in the field of orthopaedic surgery, a responsible attitude is possible neither without solid anatomical knowledge, nor without an idea of functional relationships. W. Roux had already demonstrated this and he wanted his works of functional anatomy to be considered from this point of view. He above all preoccupied himself with a uniform theory of functional adaptation. Thus it is understandable that the theories ofRoux formed the basis from which to start. Our own researches seemed at first to corroborate the ideas of Roux, at least in part. This is still evident in the monograph concerning fractures of the femoral neck. Later it appeared that ST. KROMPECHER had made a step forwards in the matter of chondrogenesis when he abandoned the shear theory postulated by Roux and held that compression was the only effective stimulus for the forma tion of cartilage. The research concerning the healing of fractures relies partly on the theory of KROMPECHER which was new at that time. But ultimately more and more discoveries could no longer be explained by this conception which was only slightly different from the older theories (1. WOLF, W. Roux, W.

Book Description
A Science News Best Science Book of the Year: “A brilliant, fun, and scientifically deep stroll through history, anatomy, and evolution.” —Agustín Fuentes, PhD, author of The Creative Spark: How Imagination Made Humans Exceptional Winner of the W.W. Howells Book Prize from the American Anthropological Association Blending history, science, and culture, this highly engaging evolutionary story explores how walking on two legs allowed humans to become the planet’s dominant species. Humans are the only mammals to walk on two rather than four legs—a locomotion known as bipedalism. We strive to be upstanding citizens, honor those who stand tall and proud, and take a stand against injustices. We follow in each other’s footsteps and celebrate a child’s beginning to walk. But why, and how, exactly, did we take our first steps? And at what cost? Bipedalism has its drawbacks: giving birth is more difficult and dangerous; our running speed is much slower than other animals; and we suffer a variety of ailments, from hernias to sinus problems. In First Steps, paleoanthropologist Jeremy DeSilva explores how unusual and extraordinary this seemingly ordinary ability is. A seven-million-year journey to the very origins of the human lineage, this book shows how upright walking was a gateway to many of the other attributes that make us human—from our technological abilities to our thirst for exploration and our use of language—and may have laid the foundation for our species’ traits of compassion, empathy, and altruism. Moving from developmental psychology labs to ancient fossil sites throughout Africa and Eurasia, DeSilva brings to life our adventure walking on two legs. Includes photographs “A book that strides confidently across this complex terrain, laying out what we know about how walking works, who started doing it, and when.” —The New York Times Book Review “DeSilva makes a solid scientific case with an expert history of human and ape evolution.” —Kirkus Reviews “A brisk jaunt through the history of bipedalism . . . will leave readers both informed and uplifted.” —Publishers Weekly “Breezy popular science at its best.” —Science News

Book Description
The study of primate locomotion is a unique discipline that by its nature is interdis ciplinary, drawing on and integrating research from ethology, ecology, comparative anat omy, physiology, biomechanics, paleontology, etc. When combined and focused on particular problems this diversity of approaches permits unparalleled insight into critical aspects of our evolutionary past and into a major component of the behavioral repertoire of all animals. Unfortunately, because of the structure of academia, integration of these different approaches is a rare phenomenon. For instance, papers on primate behavior tend to be published in separate specialist journals and read by subgroups of anthropologists and zoologists, thus precluding critical syntheses. In the spring of 1995 we overcame this compartmentalization by organizing a con ference that brought together experts with many different perspectives on primate locomo tion to address the current state of the field and to consider where we go from here. The conference, Primate Locomotion-1995, took place thirty years after the pioneering confer ence on the same topic that was convened by the late Warren G. Kinzey at Davis in 1965.

Book Description
This book offers a critical review of the pelvic sciences—past, present and future—from an anatomical and physiological perspective and is intended for researchers, medical practitioners and paramedical therapists in the fields of urology, gynecology and obstetrics, proctology, physiotherapy, as well as for patients. The book starts with a “construction plan” of the pelvis and shows its structural consequences. The historical background of pelvic studies proceeds from medieval and early Italian models to the definitive understanding of the pelvic anatomy in the Seventeenth century. During these eras of pelvic research, concepts and approaches developed that are illustrated with examples from comparative anatomy and from mutations, also with regard to the biomechanics of pelvic structures. Perceptions of the pelvis as an important element in sexual arousal and mating conduct are discussed, as well as attitudes to circumcision, castration and other mutilations, in its anthropological, social context. The anatomy and physiology of the pelvic wall and its organs as well as the development of these pelvic organs are covered as a prerequisite to understanding, for example, the spread of pelvic carcinoma and male and female bladder muscle function. Connective pelvic tissue is examined in its reinforcing capacity for pelvic structures, but also as a “hiding place” for infections. Innervations and reflexes relayed through the pelvic nerves are discussed in order to explain incontinence, sphincter function and the control of smooth and striated muscles in the pelvis. Catheters and drugs acting on pelvic function are described, and a critical review of alternative clinical methods for treating pelvic dysfunctions is provided.

Book Description
As in the bestselling The Alphabet Versus the Goddess, Leonard Shlain’s provocative new book promises to change the way readers view themselves and where they came from. Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female’s pelvis and the increasing size of infants’ heads precipitated a crisis for the species. Natural selection allowed for the adaptation of the human female to this environmental stress by reconfiguring her hormonal cycles, entraining them with the periodicity of the moon. The results, however, did much more than ensure our existence; they imbued women with the concept of time, and gave them control over sex—a power that males sought to reclaim. And the possibility of achieving immortality through heirs drove men to construct patriarchal cultures that went on to dominate so much of human history. From the nature of courtship to the evolution of language, Shlain’s brilliant and wide-ranging exploration stimulates new thinking about very old matters.
