Icons of Life


Book Description

Icons of Life tells the engrossing and provocative story of an early twentieth-century undertaking, the Carnegie Institution of Washington's project to collect thousands of embryos for scientific study. Lynn M. Morgan blends social analysis, sleuthing, and humor to trace the history of specimen collecting. In the process, she illuminates how a hundred-year-old scientific endeavor continues to be felt in today's fraught arena of maternal and fetal politics. Until the embryo collecting project-which she follows from the Johns Hopkins anatomy department, through Baltimore foundling homes, and all the way to China-most people had no idea what human embryos looked like. But by the 1950s, modern citizens saw in embryos an image of "ourselves unborn," and embryology had developed a biologically based story about how we came to be. Morgan explains how dead specimens paradoxically became icons of life, how embryos were generated as social artifacts separate from pregnant women, and how a fetus thwarted Gertrude Stein's medical career. By resurrecting a nearly forgotten scientific project, Morgan sheds light on the roots of a modern origin story and raises the still controversial issue of how we decide what embryos mean.




Born in Africa


Book Description

Africa does not give up its secrets easily. Buried there lie answers about the origins of humankind and the dawn of civilisation. Through a century of archaeological investigation, scientists have transformed our understanding of the beginnings of human life, although vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about our human origins made by scientists over the last hundred years, as well as describing the history of scholarship in this incredibly exciting field. He relates the intense rivalries, personal feuds and fierce controversies that shaped the study and perception of Africa, and recounts the feats of skill and endurance that have illuminated thousands of years of human evolution. The results have been momentous. Scientists have identified more than twenty species of extinct humans and firmly established Africa as the birthplace not only of humankind, but also of our own species: homo sapiens, the modern human. Scientific study has revealed how early technology, language ability and artistic endeavour all originated in Africa, and scientists have shown how, in an exodus sixty thousand years ago, small groups of Africans left their birthplace to populate the rest of the world. We all have an African legacy, and in this fascinating and informative book Martin Meredith leads us back to the place where we have rediscovered our common human heritage.




The Evolution of Human Life History


Book Description

Human beings may share 98 percent of their genetic makeup with their nonhuman primate cousins, but they have distinctive life histories. When and why did these uniquely human patterns evolve? To answer that question, this volume brings together specialists in hunter-gatherer behavioral ecology and demography, human growth, development, and nutrition, paleodemography, human paleontology, primatology, and the genomics of aging. The contributors identify and explain the peculiar features of human life histories, such as the rate and timing of processes that directly influence survival and reproduction. Drawing on new evidence from paleoanthropology, they question existing arguments that link human's extended childhood dependency and long 'post-reproductive'lives to brain development, learning, and distinctively human social structures. The volume reviews alternative explanations for the distinctiveness of human life history and incorporates multiple lines of evidence in order to test them.




The Origins of Human Society


Book Description

The Origins of Human Society traces the development of human culture from its origins over 2 million years ago to the emergence of literate civilization. In addition to a global coverage of prehistoric life, the book pays specific attention to the origins and dispersal of anatomically-modern humans, the development of symbolic expression, the transition from mobile foraging bands to sedentary households, early agriculture and its consequences, the emergence of social differentiation and hereditary ranking, and the prehistoric roots of ancient states and empires. The Blackwell History of the World Series The goal of this ambitious series is to provide an accessible source of knowledge about the entire human past, for every curious person in every part of the world. It will comprise some two dozen volumes, of which some provide synoptic views of the history of particular regions while others consider the world as a whole during a particular period of time. The volumes are narrative in form, giving balanced attention to social and cultural history (in the broadest sense) as well as to institutional development and political change. Each provides a systematic account of a very large subject, but they are also both imaginative and interpretative. The Series is intended to be accessible to the widest possible readership, and the accessibility of its volumes is matched by the style of presentation and production.




The Value of a Human Life


Book Description

Experts from different disciplines present new insights into the subject of ritual homicide in various regions of the ancient world.




A Brief History of the Human Race


Book Description

Why has human history been crowded into the last few thousand years? Why has it happened at all? Could it have happened in a radically different way? What should we make of the disproportionate role of the West in shaping the world we currently live in? This witty, intelligent hopscotch through human history addresses these questions and more. Michael Cook sifts the human career on earth for the most telling nuggets and then uses them to elucidate the whole. From the calendars of Mesoamerica and the temple courtesans of medieval India to the intricacies of marriage among an aboriginal Australian tribe, Cook explains the sometimes eccentric variety in human cultural expression. He guides us from the prehistoric origins of human history across the globe through the increasing unification of the world, first by Muslims and then by European Christians in the modern period, illuminating the contingencies that have governed broad historical change. "A smart, literate survey of human life from paleolithic times until 9/11."—Edward Rothstein, The New York Times




The Beginning of Human Life


Book Description

Progress in biomedical science has called for an international discussion of the medical, ethical, and legal problems that confront physicians, medical researchers, infertile couples, pregnant women, and parents of premature or disabled infants. In addition, the unprecedented technological developments in obstetrical, perinatal, and neonatal medicine in recent years have indicated a need for an international forum for interdisciplinary dialogue regarding the definition of early human life, the neurological development of early human life, the value of early human life, the obligations for its protection and prolongation, and the limits to these obligations.




Prehistory


Book Description

Recent archaeological discoveries from China and central Asia have changed our understanding of how human civilization developed in the period of some 4 million years before the start of written history. In this new edition of his Very Short Introduction, Chris Gosden explores the current theories on the ebb and flow of human cultural variety.




The Origins of Life


Book Description

Life arose on Earth more than three billion years ago. How the first self-replicating systems emerged from prebiotic chemistry and evolved into primitive cell-like entities is an area of intense research, spanning molecular and cellular biology, organic chemistry, cosmology, geology, and atmospheric science. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology provides a comprehensive account of the environment of the early Earth and the mechanisms by which the organic molecules present may have self-assembled to form replicating material such as RNA and other polymers. The contributors examine the energetic requirements for this process and focus in particular on the essential role of semi-permeable compartments in containment of primitive genetic systems. Also covered in the book are new synthetic approaches for fabricating cellular systems, the potentially extraterrestrial origin of life's building blocks, and the possibility that life once existed on Mars. Comprising five sections Setting the Stage, Components of First Life, Primitive Systems, First Polymers, and Transition to a Microbial World it is a vital reference for all scientists interested in the origin of life on Earth and the likelihood that it has arisen on other planets
