DOWNLOAD EBOOK →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.

Additionally, as technology improves, we have begun the vast task of actually quantifying the variation of this complex three-dimensional shape and comparing across and between populations. All of these different studies - functional, morphological, developmental - offer important clues towards a better understanding of hominin evolution, sexual dimorphism, morphological modularity and development constraints. In this volume, people at the forefront of work on the pelvis will process and expand our knowledge in order to explain the evolutionary mechanisms acting on hominin pelvic morphology"--

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →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.
