Book excerpt: “An enjoyable read that provides a substantial amount of detail on the biology, ecology, and distribution of these fantastic animals . . . Highly recommended.” —Choice More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans. It places these giants within the context of the other mammals then alive, describing their paleobiology—how they walked; how much they weighed; their diets, behavior, biomechanics; and the interactions among them and with their environment. It also tells the stories of the scientists who contributed to our discovery and knowledge of these transcendent creatures and the environment they inhabited. The episode known as the Great American Biotic Interchange, perhaps the most important of all natural history “experiments,” is also an important theme of the book, tracing the biotic events of both North and South America that led to the fauna and the ecosystems discussed in this book. “Collectively, this book brings attention to the discovery and natural history of ancient beasts in South America while providing a broader temporal and geographic background that allows readers to understand their evolution and potential immigration to South America.” —Quarterly Review of Biology “An excellent volume . . . This book is likely to facilitate progress in the understanding of fossil mammals from the Americas.” —Priscum

Book Synopsis End of the Megafauna: The Fate of the World's Hugest, Fiercest, and Strangest Animals by : Ross D E MacPhee

Download or read book End of the Megafauna: The Fate of the World's Hugest, Fiercest, and Strangest Animals written by Ross D E MacPhee. This book was released on 2018-11-13. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Megafauna written by Baz Edmeades. This book was released on 2021-11-10. Available in PDF, EPUB and Kindle. Book excerpt: 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.
