An accomplished paleontologist describes the amazing Cambrian fossils of the Burgess Shale, a deposit in Western Canada, recreates the diversity of life as it existed when the fossils were formed, and critiques Stephen Jay Gould's observations on the find. UP.
A study of the Burgess Shale, a sea bed 530 million years old, and attempts to tackle what the findings are and what it means
Photographs by Chip Clark. Main Selection of the Natural Science Book Club. This book provides the first comprehensive set of illustrations of the life forms revealed in the Burgess Shale. This century's most significant invertebrate fossil discovery, the Burgess Shale provides an unprecendented window ito the explosive evolution during the Cambrian Period.
How did human beings acquire imaginations that can conjure up untrue possibilities? How did the Universe become self-aware? In The Runes of Evolution, Simon Conway Morris revitalizes the study of evolution from the perspective of convergence, providing us with compelling new evidence to support the mounting scientific view that the history of life is far more predictable than once thought. A leading evolutionary biologist at the University of Cambridge, Conway Morris came into international prominence for his work on the Cambrian explosion (especially fossils of the Burgess Shale) and evolutionary convergence, which is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. In The Runes of Evolution, he illustrates how the ubiquity of convergence hints at an underlying framework whereby many outcomes, not least brains and intelligence, are virtually guaranteed on any Earth-like planet. Conway Morris also emphasizes how much of the complexity of advanced biological systems is inherent in microbial forms. By casting a wider net, The Runes of Evolution explores many neglected evolutionary questions. Some are remarkably general. Why, for example, are convergences such as parasitism, carnivory, and nitrogen fixation in plants concentrated in particular taxonomic hot spots? Why do certain groups have a particular propensity to evolve toward particular states? Some questions lead to unexpected evolutionary insights: If bees sleep (as they do), do they dream? Why is that insect copulating with an orchid? Why have sponges evolved a system of fiber optics? What do mantis shrimps and submarines have in common? If dinosaurs had not gone extinct what would have happened next? Will a saber-toothed cat ever re-evolve? Cona Morris observes: “Even amongst the mammals, let alone the entire tree of life, humans represent one minute twig of a vast (and largely fossilized) arborescence. Every living species is a linear descendant of an immense string of now-vanished ancestors, but evolution itself is the very reverse of linear. Rather it is endlessly exploratory, probing the vast spaces of biological hyperspace. Indeed this book is a celebration of how our world is (and was) populated by a riot of forms, a coruscating tapestry of life.” The Runes of Evolution is the most definitive synthesis of evolutionary convergence to be published to date.
What makes geniuses different from the rest of us? What is the difference between a prodigy and a genius? Are geniuses born or made? What is creative vision and where does it come from? What are the secrets of talent? And why do great creators seem to have so many oppositions in their personalities? In this mind-expanding investigation of creativity, John Briggs reveals that there is no special trait of genius. Geniuses are not necessarily smarter or more talented than other people, but they give their attention to subtle nuances, contradictory feelings and perceptions that others experience and ignore. By focusing on sensory nuances, geniuses create themselves. Fire in the Crucible offers a compelling exploration of the roots of creativity and genius. Drawing on the lives and work of extraordinary scientists, artists, writers, composers, and inventors, Briggs shows how creative individuals exploit doubt and uncertainty, and the mental strategies and tactics they employ when they work. "In asking about creativity," he writes, "we are really asking about what is best, what is deepest in life." Fire in the Crucible draws the reader into an eye-opening journey through the inner workings of some of the greatest creative minds of all times -- and allows us to more deeply understand the nature of the creativity in our own lives and work.
Life's Solution builds a persuasive case for the predictability of evolutionary outcomes. The case rests on a remarkable compilation of examples of convergent evolution, in which two or more lineages have independently evolved similar structures and functions. The examples range from the aerodynamics of hovering moths and hummingbirds to the use of silk by spiders and some insects to capture prey. Going against the grain of Darwinian orthodoxy, this book is a must read for anyone grappling with the meaning of evolution and our place in the Universe. Simon Conway Morris is the Ad Hominen Professor in the Earth Science Department at the University of Cambridge and a Fellow of St. John's College and the Royal Society. His research focuses on the study of constraints on evolution, and the historical processes that lead to the emergence of complexity, especially with respect to the construction of the major animal body parts in the Cambrian explosion. Previous books include The Crucible of Creation (Getty Center for Education in the Arts, 1999) and co-author of Solnhofen (Cambridge, 1990). Hb ISBN (2003) 0-521-82704-3
The celebrated lower Cambrian Chengjiang biota of Yunnan Province, China, represents one of the most significant ever paleontological discoveries. Deposits of ancient mudstone, about 520 million years old, have yielded a spectacular variety of exquisitely preserved fossils that record the early diversification of animal life. Since the discovery of the first specimens in 1984, many thousands of fossils have been collected, exceptionally preserving not just the shells and carapaces of the animals, but also their soft tissues in fine detail. This special preservation has produced fossils of rare beauty; they are also of outstanding scientific importance as sources of evidence about the origins of animal groups that have sustained global biodiversity to the present day. Much of the scientific documentation of the Chengjiang biota is in Chinese, and the first edition of this book was the first in English to provide fossil enthusiasts with a comprehensive overview of the fauna. The second edition has been fully updated and includes a new chapter on other exceptionally preserved fossils of Cambrian age, exciting new fossil finds from Chengjiang, and a phylogenetic framework for the biota. Displaying some 250 figures of marvelous specimens, this book presents to professional and amateur paleontologists, and all those fascinated by evolutionary biology, the aesthetic and scientific quality of the Chengjiang fossils.
In his bestselling The Moral Animal, Robert Wright applied the principles of evolutionary biology to the study of the human mind. Now Wright attempts something even more ambitious: explaining the direction of evolution and human history–and discerning where history will lead us next. In Nonzero: The Logic of Human Destiny, Wright asserts that, ever since the primordial ooze, life has followed a basic pattern. Organisms and human societies alike have grown more complex by mastering the challenges of internal cooperation. Wright's narrative ranges from fossilized bacteria to vampire bats, from stone-age villages to the World Trade Organization, uncovering such surprises as the benefits of barbarian hordes and the useful stability of feudalism. Here is history endowed with moral significance–a way of looking at our biological and cultural evolution that suggests, refreshingly, that human morality has improved over time, and that our instinct to discover meaning may itself serve a higher purpose. Insightful, witty, profound, Nonzero offers breathtaking implications for what we believe and how we adapt to technology's ongoing transformation of the world. From the Trade Paperback edition.
In 1803 the United States purchased Louisiana from France. This seemingly simple acquisition brought with it an enormous new territory as well as the country’s first large population of nonnaturalized Americans—Native Americans, African Americans, and Francophone residents. What would become of those people dominated national affairs in the years that followed. This book chronicles that contentious period from 1803 to 1821, years during which people proposed numerous visions of the future for Louisiana and the United States. The Louisiana Purchase proved to be the crucible of American nationhood, Peter Kastor argues. The incorporation of Louisiana was among the most important tasks for a generation of federal policymakers. It also transformed the way people defined what it meant to be an American.
Little is known about sixth-century Arabia. Yet from this distant time and place emerged a faith and an empire that stretched from Iberia to India. G. W. Bowersock illuminates this obscure yet most dynamic period in Islam, exploring why arid Arabia proved to be fertile ground for Muhammad’s message and why it spread so quickly to the wider world.
Religion is commonly viewed through the lens of the world's religious traditions, stressing the differences, and often the conflicts, among them. The author of this book instead presents religion as a common and universal human phenomenon, based deeply in a human nature shared by all. In this view, the underlining and unifying principle of religion is a particular affirmative attitude toward life, which he presents as the Ultimate Value, and as such the key cultural constituent and defining factor of all religion. This Ultimate Value finds its expressions in various civilizations, and results in a variety of forms; these are what we know as the world's religious traditions. By analyzing the roles of both culture and civilization in their attitudes toward life, the author places religion beyond religious traditions, and shows how the latter, regardless of whether they are theistic or atheistic, draw their principles from the former, mainly by promoting the Golden Rule in its applications.
An interdisciplinary book for scientists interested in the origin and existence of life in our universe, first published in 2007.
The assassin's bullet misses, the Archduke's carriage moves forward, and a catastrophic war is avoided. So too with the history of life. Re-run the tape of life, as Stephen J. Gould claimed, and the outcome must be entirely different: an alien world, without humans and maybe not even intelligence. The history of life is littered with accidents: any twist or turn may lead to a completely different world. Now this view is being challenged. Simon Conway Morris explores the evidence demonstrating life's almost eerie ability to navigate to a single solution, repeatedly. Eyes, brains, tools, even culture: all are very much on the cards. So if these are all evolutionary inevitabilities, where are our counterparts across the galaxy? The tape of life can only run on a suitable planet, and it seems that such Earth-like planets may be much rarer than hoped. Inevitable humans, yes, but in a lonely Universe.
From the two-time Pulitzer Prize–winning author, God’s Crucible brings to life “a furiously complex age” (New York Times Book Review). Resonating as profoundly today as when it was first published to widespread critical acclaim a decade ago, God’s Crucible is a bold portrait of Islamic Spain and the birth of modern Europe from one of our greatest historians. David Levering Lewis’s narrative, filled with accounts of some of the most epic battles in world history, reveals how cosmopolitan, Muslim al-Andalus flourished—a beacon of cooperation and tolerance—while proto-Europe floundered in opposition to Islam, making virtues out of hereditary aristocracy, religious intolerance, perpetual war, and slavery. This masterful history begins with the fall of the Persian and Roman empires, followed by the rise of the prophet Muhammad and five centuries of engagement between the Muslim imperium and an emerging Europe. Essential and urgent, God’s Crucible underscores the importance of these early, world-altering events whose influence remains as current as today’s headlines.
Including twenty-two photographs and more than fifty drawings of these strikingly beautiful early life forms, this book presents a mesmerizing documentary of a major scientific discovery: the oldest animal fossils ever discovered.
One of America's foremost scholars of religion examines the tumultuous era that gave birth to the modern Judeo-Christian tradition In The Crucible of Faith, Philip Jenkins argues that much of the Judeo-Christian tradition we know today was born between 250-50 BCE, during a turbulent "Crucible Era." It was during these years that Judaism grappled with Hellenizing forces and produced new religious ideas that reflected and responded to their changing world. By the time of the fall of the Temple in 70 CE, concepts that might once have seemed bizarre became normalized-and thus passed on to Christianity and later Islam. Drawing widely on contemporary sources from outside the canonical Old and New Testaments, Jenkins reveals an era of political violence and social upheaval that ultimately gave birth to entirely new ideas about religion, the afterlife, Creation and the Fall, and the nature of God and Satan.
From the barbed, childish taunt on the school playground, to the eloquent sophistry of a lawyer prising open a legal loophole in a court of law, meaning arises each time we use language to communicate with one another. How we use language - to convey ideas, make requests, ask a favour, and express anger, love or dismay - is of the utmost importance; indeed, linguistic meaning can be a matter of life and death. In The Crucible of Language, Vyvyan Evans explains what we know, and what we do, when we communicate using language; he shows how linguistic meaning arises, where it comes from, and the way language enables us to convey the meanings that can move us to tears, bore us to death, or make us dizzy with delight. Meaning is, he argues, one of the final frontiers in the mapping of the human mind.
