Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

The New Neotropical Companion is the completely revised and expanded edition of a book that has helped thousands of people to understand the complex ecology and natural history of the most species-rich area on Earth, the American tropics. Featuring stunning color photos throughout, it is a sweeping and cutting-edge account of tropical ecology that includes not only tropical rain forests but also other ecosystems such as cloud forests, rivers, savannas, and mountains. This is the only guide to the American tropics that is all-inclusive, encompassing the entire region's ecology and the amazing relationships among species rather than focusing just on species identification. The New Neotropical Companion is a book unlike any other. Here, you will learn how to recognize distinctive ecological patterns of rain forests and other habitats and to interpret how these remarkable ecosystems function—everything is explained in clear and engaging prose free of jargon. You will also be introduced to the region's astonishing plant and animal life. Informative and entertaining, The New Neotropical Companion is a pleasurable escape for armchair naturalists, and visitors to the American tropics will want to refer to this book before, during, and after their trip. Covers all of tropical America Describes the species and habitats most likely to be observed by visitors Includes every major ecosystem, from lowland rain forests to the high Andes Features a wealth of color photos of habitats, plants, and animals

In 1905, eight men from the California Academy of Sciences set sail from San Francisco for a scientific collection expedition in the Galapagos Islands, and by the time they were finished in 1906, they had completed one of the most important expeditions in the history of both evolutionary and conservation science. These scientists collected over 78,000 specimens during their time on the islands, validating the work of Charles Darwin and laying the groundwork for foundational evolution texts like Darwin's Finches. Despite its significance, almost nothing has been written on this voyage, lost amongst discussion of Darwin's trip on the Beagle and the writing of David Lack. In Collecting Evolution, author Matthew James finally tells the story of the 1905 Galapagos expedition. James follows these eight young men aboard the Academy to the Galapagos and back, and reveals the reasons behind the groundbreaking success they had. A current Fellow of the California Academy of Sciences, James uses his access to unpublished writings and photographs to provide unprecedented insight into the expedition. We learn the voyagers' personal stories, and how, for all the scientific progress that was made, just as much intense personal drama unfolded on the trip. This book shares a watershed moment in scientific history, crossed with a maritime adventure. There are four tangential suicides and controversies over credit and fame. Collecting Evolution also explores the personal lives and scientific context that preceded this voyage, including what brought Darwin to the Galapagos on the Beagle voyage seventy years earlier. James discusses how these men thought of themselves as "collectors" before they thought of themselves as scientists, and the implications this had on their approach and their results. In the end, the voyage of the Academy proved to be crucial in the development of evolutionary science as we know it. It is the longest expedition in Galapagos history, and played a critical role in cementing Darwin's legacy. Collecting Evolution brings this extraordinary story of eight scientists and their journey to life.
