How does one make decisions today about in vitro fertilization, abortion, egg freezing, surrogacy, and other matters of reproduction? This book provides the intellectual and emotional intelligence to help individuals make informed choices amid misinformation and competing claims. Scott Gilbert and Clara Pinto-Correia speak to the couple trying to become pregnant, the woman contemplating an abortion, and the student searching for sound information about human sex and reproduction. Their book is an enlightening read for men as well as for women, describing in clear terms how babies come into existence through both natural and assisted reproductive pathways. They update “the talk” for the twenty-first century: the birds, the bees, and the Petri dishes. Fear, Wonder, and Science in the New Age of Reproductive Biotechnology first covers the most recent and well-grounded scientific conclusions about fertilization and early human embryology. It then discusses the reasons why some of the major forms of assisted reproductive technologies were invented, how they are used, and what they can and cannot accomplish. Most important, the authors explore the emotional side of using these technologies, focusing on those who have emptied their emotions and bank accounts in a valiant effort to conceive a child. This work of science and human biology is informed by a moral concern for our common humanity.
A new account of the central role developmental processes play in evolution A new scientific view of evolution is emerging—one that challenges and expands our understanding of how evolution works. Recent research demonstrates that organisms differ greatly in how effective they are at evolving. Whether and how each organism adapts and diversifies depends critically on the mechanistic details of how that organism operates—its development, physiology, and behavior. That is because the evolutionary process itself has evolved over time, and continues to evolve. The scientific understanding of evolution is evolving too, with groundbreaking new ways of explaining evolutionary change. In this book, a group of leading biologists draw on the latest findings in evolutionary genetics and evo-devo, as well as novel insights from studies of epigenetics, symbiosis, and inheritance, to examine the central role that developmental processes play in evolution. Written in an accessible style, and illustrated with fascinating examples of natural history, the book presents recent scientific discoveries that expand evolutionary biology beyond the classical view of gene transmission guided by natural selection. Without undermining the central importance of natural selection and other Darwinian foundations, new developmental insights indicate that all organisms possess their own characteristic sets of evolutionary mechanisms. The authors argue that a consideration of developmental phenomena is needed for evolutionary biologists to generate better explanations for adaptation and biodiversity. This book provides a new vision of adaptive evolution.
This brief textbook of human development covers the events of fertilization, gestation, and sex determination, followed by descriptions of the science of cloning, stem cells, and genome sequencing. The chapter covering the science is juxtaposed with a chapter discussing ethical questions that arise, such as when does life begin, should assisted reproductive technologies be regulated, and should parents be allowed to choose their child's sex"--Provided by publisher.
New in paperback Spring 2004, this is an indispensable guide to agaves. The uses of agaves are as many as the arts of man have found it convenient to devise. At least two races of man have invaded Agaveland during the last ten to fifteen thousand years, where, with the help of agaves, they contrived several successive civilizations. The region of greatest use development is Mesoamerica. Here the great genetic diversity in a genus rich in use potential came into the hands of several peoples who developed the main agricultural center of the Americas. Perhaps, as the Aztec legends suggest, it was the animals that first showed man the edibility of agave. Evolution in use ranges all the way from the coincidental and spurious, through tool and food-drink subsistence with mystical overlay, to the practical specialties of modem industry and art. The historic period of agave will be outlined here as briefly as that complicated development will allow.
The debate over Intelligent Design seemingly represents an extension of the fundamental conflict between creationists and evolutionists. ID proponents, drawing on texts such as Darwin's Black Box and Of Pandas and People, urge schools to "teach the controversy" in biology class alongside evolution. The scientific mainstream has reacted with fury, branding Intelligent Design as pseudoscience and its advocates as religious fanatics. But stridency misses the point, argues Nathaniel Comfort. In The Panda's Black Box, Comfort joins five other leading public intellectuals—including Daniel Kevles and Pulitzer Prize winner Edward Larson—to explain the roots of the controversy and explore the intellectual, social, and cultural factors that continue to shape it. One of the few books on the ID issue that moves beyond mere name-calling and finger-pointing, The Panda's Black Box challenges assumptions on each side of the debate and engages both the appeal and dangers of Intelligent Design. This lively collection will appeal to anyone seeking a deeper understanding of what's really at stake in the debate over evolution.
