Book Description
Ecological competition began as slow arms races. Predators evolved to hunt. Prey evolved to defend themselves. Each improvement was small, barely shifting the odds of survival. Nature remained in equilibrium. Until the dawn of humanity. When our ancestors developed the unique ability to think up new devices and behaviors, humanity became able to overcome nature's defenses far more quickly than natural selection could respond. Humankind spread out of Africa, wiping out most of the megafauna in its path-mammoths, sabertooth cats, elephant-sized sloths, and a great many other species. Today, this formidable, inventive genius of our species-now grown to overwhelming and all-conquering proportions-is threatening to make the earth unlivable, even for ourselves. The only weapon available to us to counter this threat is, ironically, the same one that unleashed our destructiveness in the first place: the analytical and creative power of the human brain.

Book Description
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.

Book Description
ONE OF THE NEW YORK TIMES BOOK REVIEW'S 10 BEST BOOKS OF THE YEAR A major book about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes Over the last half a billion years, there have been five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In The Sixth Extinction, two-time winner of the National Magazine Award and New Yorker writer Elizabeth Kolbert draws on the work of scores of researchers in half a dozen disciplines, accompanying many of them into the field: geologists who study deep ocean cores, botanists who follow the tree line as it climbs up the Andes, marine biologists who dive off the Great Barrier Reef. She introduces us to a dozen species, some already gone, others facing extinction, including the Panamian golden frog, staghorn coral, the great auk, and the Sumatran rhino. Through these stories, Kolbert provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy; as Kolbert observes, it compels us to rethink the fundamental question of what it means to be human.

Book Description
To help us understand what happened during the Ice Age, Peter Ward takes us on a tour of other mass extinctions through earth's history. He presents a compelling account of the great comet crash that killed off the dinosaurs, and describes other extinctions that were even more extensive. In so doing, he introduces us to a profound paradigm shift now taking place in paleontology: rather than arising from the gradual workings of everyday forces, all mass extinctions are due to unique, catastrophic events. Written with an irresistible combination of passion and expertise, The Call of Distant Mammoths is an engaging exploration of the history of life and the importance of humanity as an evolutionary force. "Carefully argued...an intelligent and compelling book."-THE OLYMPIAN, SEATTLE, WASHINGTON "Ward deftly summarizes a large body of scientific literature, simplifying complex ideas for the general reader without condescension."-PUBLISHERS WEEKLY "Did the overkill really happen?...Peter Ward deftly summarizes the arguments...Ward tells (the story) well."-THE NEW SCIENTIST

Book Description
Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

Book Description
Life is a rarity. We know of no other planet where life exists other than on Earth. Life started out in a most simple form, then proceeded along a labyrinth of evolutionary pathways that resulted in extraordinary and unfathomable designs. This is a journey, from the beginning of time to this very day, guided by circumstances, contingencies, and chaos that has governed Earth's living assemblage. But life's presence was not destined to just happen. If it wasn't for our moon, which gave Earth orbital and rotational stability, life would not be as we know it today. If it wasn't for volcanic eruptions, Earth would be an ice-clad, frozen globe. If it wasn't for one of the tiniest of living organisms that produced a toxic gas, complex life would not have arisen. If it wasn't for one particular extinction event, Homo sapiens would not be walking this planet, and you would not be reading this now. If it wasn't for a million other things, life would be much different, or not at all. Earth made life, from the meek to the monstrous, from the banal to the bizarre, from the humblest to the haughtiest. Strap yourself in alongside a window seat and witness the passing of time, to view the episodes of change, and how the making of life became the greatest story on Earth.

Book Description
Everyone is familiar with the dodo and the wooly mammoth, but how many people have heard of the scimitar cat and the Falkland Island fox? Extinct Animals portrays over 60 remarkable animals that have been lost forever during the relatively recent geological past. Each entry provides a concise discussion of the history of the animal—how and where it lived, and how it became extinct—as well as the scientific discovery and analysis of the creature. In addition, this work examines what led to extinction—from the role of cyclical swings in the Earth's climate to the spread of humans and their activities. Many scientists believe that we are in the middle of a mass extinction right now, caused by the human undermining of the earth's complex systems that support life. Understanding what caused the extinction of animals in the past may help us understand and prevent the extinction of species in the future. Extinct Animals examines the biology and history of some of the most interesting creatures that have ever lived, including: The American Terror Bird, which probably became extinct over 1 million years ago, who were massive predators, some of which were almost 10 feet tall; the Rocky Mountain Locust, last seen in 1902, formed the most immense animal aggregations ever known, with swarms estimated to include over 10 trillion insects; the Giant Ground Sloth, which was as large as an elephant; and the Neandertals, the first Europeans, which co-existed with prehistoric Homo sapiens. Extinct Animals includes illustrations—many created for the work—that help the reader visualize the extinct creature, and each entry concludes with a list of resources for those who wish to do further research.

Book Description
A Times Higher Education Book of the Week Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe—descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished. Ever since the first Neanderthal bones were identified in 1856, scientists have been vexed by the question, why did modern humans survive while their closest known relatives went extinct? “Shipman admits that scientists have yet to find genetic evidence that would prove her theory. Time will tell if she’s right. For now, read this book for an engagingly comprehensive overview of the rapidly evolving understanding of our own origins.” —Toby Lester, Wall Street Journal “Are humans the ultimate invasive species? So contends anthropologist Pat Shipman—and Neanderthals, she opines, were among our first victims. The relationship between Homo sapiens and Homo neanderthalensis is laid out cleanly, along with genetic and other evidence. Shipman posits provocatively that the deciding factor in the triumph of our ancestors was the domestication of wolves.” —Daniel Cressey, Nature
