Böcker av Niles Eldredge

How is our fate linked to the earth's creatures, and the cycle of flourishing and extinction? Does human activity accelerate extinction? And what really causes it? This account of the widespread reduction of the world's wildlife examines humankind's role in the larger life cycles of the earth, composing a provocative general theory of extinction.

All organisms and species are transitory, yet life endures. The origin, extinction, and evolution of species-interconnected in the web of life as "e;eternal ephemera"e;-are the concern of evolutionary biology. In this riveting work, renowned paleontologist Niles Eldredge follows leading thinkers as they have wrestled for more than two hundred years with the eternal skein of life composed of ephemeral beings, revitalizing evolutionary science with their own, more resilient findings.Eldredge begins in France with the naturalist Jean-Baptiste Lamarck, who in 1801 first framed the overarching question about the emergence of new species. The Italian geologist Giambattista Brocchi followed, bringing in geology and paleontology to expand the question. In 1825, at the University of Edinburgh, Robert Grant and Robert Jameson introduced the astounding ideas formulated by Lamarck and Brocchi to a young medical student named Charles Darwin. Who can doubt that Darwin left for his voyage on the Beagle in 1831 filled with thoughts about these daring new explanations for the "e;transmutation"e; of species.Eldredge revisits Darwin's early insights into evolution in South America and his later synthesis of knowledge into a theory of the origin of species. He then considers the ideas of more recent evolutionary thinkers, such as George Gaylord Simpson, Ernst Mayr, and Theodosius Dobzhansky, as well as the young and brash Niles Eldredge and Steven Jay Gould, who set science afire with their concept of punctuated equilibria. Filled with insights into evolutionary biology and told with a rich affection for the scientific arena, this book celebrates the organic, vital relationship between scientific thinking and its subjects.

If they are to survive, cities need healthy chunks of the world's ecosystems to persist; yet cities, like parasites, grow and prosper by local destruction of these very ecosystems. In this absorbing and wide-ranging book, Eldredge and Horenstein use New York City as a microcosm to explore both the positive and the negative sides of the relationship between cities, the environment, and the future of global biodiversity. They illuminate the mass of contradictions that cities present in embodying the best and the worst of human existence. The authors demonstrate that, though cities have voracious appetites for resources such as food and water, they also represent the last hope for conserving healthy remnants of the world's ecosystems and species. With their concentration of human beings, cities bring together centers of learning, research, government, finance, and media-institutions that increasingly play active roles in solving environmental problems. Some of the topics covered in Concrete Jungle: --The geological history of the New York region, including remnant glacial features visible today --The early days of urbanization on Manhattan Island, focusing on the history of Central Park, Collect Pond, and Manhattan Square --The history of early railway lines and the development of New York's iconic subway system --The problem of producing enough safe drinking water for an ever-expanding population --Prominent civic institutions, including universities, museums, and zoos

In this text, palaeontologist Niles Eldredge reviews the relation between biological and cultural evolution, showing how the agricultural revolution freed humans from dependence on local ecosystems and allowed us to assert our dominion, as the Christian Bible has it, over the beasts and the field.

A major refutation of the almighty status of genes in evolution and human behavior.

Argues that the Earth is confronting a disaster in the making - an ecological crisis that, if left unresolved, could lead to mass extinction on the scale of that which killed the dinosaurs. This book reviews evidence for this "biodiversity crisis" ', showing that species are dying out at an unnaturally rapid rate.

A riveting tribute to Charles Darwin's life and ideas in celebration of his 200th birthday.
