This work explains how scientists who study the field of complexity are convinced that certain constant processes are at work in all kinds of unrelated complex systems. The author also illustrates the relevance of scientific debate to the layman.
An explorer of that most wondrous of islands, the human brain, writes D.M. Thomas in The New York Times Book Review, Oliver Sacks also loves the oceanic kind of islands. Both kinds figure movingly in this book--part travelogue, part autobiography, part medical mystery story--in which Sacks's journeys to a tiny Pacific atoll and the island of Guam become explorations of the meaning of islands, the genesis of disease, the wonders of botany, the nature of deep geological time, and the complexities of being human.
The ability of proteins to fold rapidly and efficiently into intricate and highly specific structures following their synthesis on ribosomes is an essential part of the conversion of genetic information into cellular activity. However, little is understood in detail of how this occurs. The Royal Society meeting on which this volume is based focused on the molecular basis of the folding processes and brought together a wide range of leading experimental and theoretical scientists in this field. This volume offers an authoritative collection of the foundations of current work. The first section discusses the experimental elucidation of the pathways of protein folding. The second section looks at theoretical approaches to folding, and the final group addresses the issue of how proteins fold in vivo. This volume will be of value to all those with an interest in protein folding, especially those in molecular biology, biochemistry and cell biology.
In 1994 Bryan Sykes was called in as an expert to examine the frozen remains of a man trapped in glacial ice in northern Italy for over 5000 years--the Ice Man. Sykes succeeded in extracting DNA from the Ice Man, but even more important, writes Science News, was his "ability to directly link that DNA to Europeans living today." In this groundbreaking book, Sykes reveals how the identification of a particular strand of DNA that passes unbroken through the maternal line allows scientists to trace our genetic makeup all the way back to prehistoric times--to seven primeval women, the "seven daughters of Eve."
Oliver Sacks travels once again in search of human diversity, to the South Pacific atoll of Pingelap, where he finds that a high proportion of the population is colourblind and investigates the causes and effects of that condition. This book explores the islands, the people and their case studies.
DNA, the genetic blueprint of all creatures, is a stunningly rich and detailed record of evolution. Every change or new trait, from the gaudy colors of tropical birds to our color vision with which we admire them, is due to changes in DNA that leave a record and can be traced. Just as importantly, the DNA evidence has revealed several profound surprises about how evolution actually works.
Richard Dawkins' brilliant reformulation of the theory of natural selection has the rare distinction of having provoked as much excitement and interest outside the scientific community as within it. His theories have helped change the whole nature of the study of social biology, and have forced thousands of readers to rethink their beliefs about life.
In his internationally bestselling, now classic volume, The Selfish Gene, Dawkins explains how the selfish gene can also be a subtle gene. The world of the selfish gene revolves around savage competition, ruthless exploitation, and deceit, and yet, Dawkins argues, acts of apparent altruism do exist in nature. Bees, for example, will commit suicide when they sting to protect the hive, and birds will risk their lives to warn the flock of an approaching hawk.
This 30th anniversary edition of Dawkins' fascinating book retains all original material, including the two enlightening chapters added in the second edition. In a new Introduction the author presents his thoughts thirty years after the publication of his first and most famous book, while the inclusion of the two-page original Foreword by brilliant American scientist Robert Trivers shows the enthusiastic reaction of the scientific community at that time. This edition is a celebration of a remarkable exposition of evolutionary thought, a work that has been widely hailed for its stylistic brilliance and deep scientific insights, and that continues to stimulate whole new areas of research today.
Is our nature--as individuals, as a species--determined by our evolution and encoded in our genes? If we unravel the protein sequences of our DNA, will we gain the power to cure all of our physiological and psychological afflictions and even to solve the problems of our society? Today biologists--especially geneticists--are proposing answers to questions that have long been asked by philosophy or faith or the social sciences. Their work carries the weight of scientific authority and attracts widespread public attention, but it is often based on what the renowned evolutionary biologist Richard Lewontin identifies as a highly reductive misconception: "the pervasive error that confuses the genetic state of an organism with its total physical and psychic nature as a human being."In these nine essays covering the history of modern biology from Darwin to Dolly the sheep, all of which were originally published in The New York Review of Books, Lewontin combines sharp criticisms of overreaching scientific claims with lucid expositions of the exact state of current scientific knowledge--not only what we do know, but what we don't and maybe won't anytime soon. Among the subjects he discusses are heredity and natural selection, evolutionary psychology and altruism, nineteenth-century naturalist novels, sex surveys, cloning, and the Human Genome Project. In each case he casts an ever-vigilant and deflationary eye on the temptation to look to biology for explanations of everything we want to know about our physical, mental, and social lives. These essays--several of them updated with epilogues that take account of scientific developments since they were first written--are an indispensable guide to the most controversial issues in the life sciences today. The second edition of this collection includes new essays on genetically modified food and the completion of the Human Genome Project. It is an indispensable guide to the most controversial issues in the life sciences today.
