Synopses & Reviews
Here is the extraordinary story of the unfolding of life on Earth, told by Michael J. Benton, a world-renowned authority on biodiversity. Ranging over four billion years, Benton weaves together the latest findings on fossils, earth history, evolutionary biology, and many other fields to highlight the great leaps that enabled life to evolve from microbe to human--big breakthroughs that made whole new ways of life possible--including cell division and multicellularity, hard skeletons, the move to land, the origin of forests, the move to the air. He describes the mass extinctions, especially the Permian, which obliterated 90% of life, and he sheds light on the origins of human beings, and of the many hominids that went before us. He ends by pointing out that studying the past helps us to predict the future: what happens if the atmosphere warms by 5 degrees? What happens if we destroy much of the biodiversity on Earth? These things have happened before, Benton notes. We need only look to the distant past to know the future of life on Earth.

Why Ecology? is a short, accessible, supplemental ecology text suitable for nonmajors course adoption. Divided into twelve chapters, it covers everything from the geographic distribution of organisms and the limits on population increase, to species extinction and the sunandrsquo;s role in powering ecosystems. Each chapter presents a basic ecological topic by introducing a general problem or question, illustrating the problem with current examples, and linking the problem to pressing ecological issues in which humans play a central role, such as the spread of invasive species, climate change, overfishing, and biodiversity conservation. and#160;While other ecology texts tend to focus on ecological theory and practice, and relegate discussions of human impacts and their societal implications to separate chapters, Why Ecology? weaves these discussions throughout the book, unifying its various topics and highlighting our manifold connections to ongoing, global ecological concerns. Why Ecology? ultimately provides an appreciation of ecology rooted not in complex ecological theory or math, but in our contemporary world. and#160;
