Two journalists travel to an island in the Arctic Circle where scientists are searching for fossils of extinct animals. Like all journalists, they have a lot of questions: how is it possible for an entire species to completely disappear? Word has it that we're in the midst of a sixth mass extinction, but what exactly does that mean? How did the first five happen? What is the scientific definition of an extinction? Alexandre Franc adeptly illustrates the narrative by Jean-Baptiste de Panafieu, a specialist in natural sciences and doctor of biological oceanology. Panafieu, who has already authored a number of popular science books, gives a clear explanation of what mass extinctions are, cleverly comparing past extinctions with the one we are witnessing now. The two authors present us with a clear, intelligent, and lighthearted perspective on a fascinating phenomenon.
"Paul S. Martin's innovative ideas on late quaternary extinctions and wildlife restoration have fueled one of science's most stimulating recent debates. He expounds them vividly here, and defends them eloquently. A must-read."—David Rains Wallace, author of Beasts of Eden "This is a marvelous read, by a giant in American prehistory, about one of the greatest mysteries in the earth sciences."—Tim Flannery, author of The Eternal Frontier "Whether or not you agree with Paul Martin, he has shaped how we think about our Pleistocene ancestors and their role in transforming this planet."—Ross D. E. MacPhee, Curator of Mammalogy, American Museum of Natural History
Until about 13,000 years ago, North America was home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history--and our part in it--is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face the threat of another great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.
Understanding what caused the extinction of animals in the past may help us understand and prevent the extinction of species in the future.
This book is about the philosophy of de-extinction. To make an extinct species ‘de-extinct’ is to resurrect it by creating new organisms of the same, or similar, appearance and genetics. The book describes current attempts to resurrect three species, the aurochs, woolly mammoth and passenger pigeon. It then investigates two major philosophical questions such projects throw up. These are the Authenticity Question—‘will the products of de-extinction be authentic members of the original species?’—and the Ethical Question—‘is de-extinction something that should be done?' The book surveys and critically evaluates a raft of arguments for and against the authenticity or de-extinct organisms, and for and against the ethical legitimacy of de-extinction. It concludes, first, that authentic de-extinctions are actually possible, and second, that de-extinction can potentially be ethically legitimate, especially when deployed as part of a ‘freeze now and resurrect later’ conservation strategy.
In the twenty-first century, because of climate change and other human activities, many animal species have become extinct, and many others are at risk of extinction. Once they are gone, we cannot bring them back—or can we? With techniques such as cloning, scientists want to reverse extinction and return lost species to the wild. Some scientists want to create clones of recently extinct animals, while others want to make new hybrid animals. Many people are opposed to de-extinction. Some critics say that the work diverts attention from efforts to save species that are endangered. Others say that de-extinction amounts to scientists "playing God." Explore the pros and cons of de-extinction and the cutting-edge science that makes it possible.
The fascinating lives and puzzling demise of some of the largest animals on earth. Until a few thousand years ago, creatures that could have been from a sci-fi thriller—including gorilla-sized lemurs, 500-pound birds, and crocodiles that weighed a ton or more—roamed the earth. These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone. What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses. Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.
A guide to extinctions and their many causes and impacts.
Caught on camera prior to their demise, this book reveals the surprisingly rich photographic record of now-extinct animals. A photograph of an animal long-gone evokes a feeling of loss more than a painting ever can. Often tinted sepia or black-and-white, these images were mainly taken in zoos or wildlife parks, and in a handful of cases featured the last known individual of the species. There are some familiar examples, such as Martha, the last Passenger Pigeon, or the Ivory-billed Woodpecker, recently fledged and perching happily on the hat of one of the biologists that had just ringed it. But for every Martha there are a number of less familiar extinct birds and mammals that were caught on camera. The photographic record of extinction is the focus of this remarkable book, written by the world's leading authority on vanished animals, Errol Fuller. Lost Animals features photographs dating from around 1870 to as recently as 2004, the year that saw the demise of the Hawaiian Po'ouli. From a mother Thylacine and her pups to now-extinct birds such as the Heath Hen and Carolina Parakeet, Fuller tells the tale of each animal, why it became extinct, and discusses the circumstances surrounding the photography itself, in a book rich with unique images. The photographs themselves are poignant and compelling. They provide a tangible link to animals that have now vanished forever, in a book that brings the past to life while delivering a warning for the future.
