Das egoistische Gen

Mit einem Vorwort von Wolfgang Wickler

p”Ein auch heute noch bedeutsamer Klassiker“ Daily Express Sind wir Marionetten unserer Gene? Nach Richard Dawkins ́ vor über 30 Jahren entworfener und heute noch immer provozierender These steuern und dirigieren unsere von Generation zu Generation weitergegebenen Gene uns, um sich selbst zu erhalten. Alle biologischen Organismen dienen somit vor allem dem Überleben und der Unsterblichkeit der Erbanlagen und sind letztlich nur die "Einweg-Behälter" der "egoistischen" Gene. Sind wir Menschen also unserem Gen-Schicksal hilflos ausgeliefert? Dawkins bestreitet dies und macht uns Hoffnung: Seiner Meinung nach sind wir nämlich die einzige Spezies mit der Chance, gegen ihr genetisches Schicksal anzukämpfen.

Genes, Categories, and Species

The Evolutionary and Cognitive Cause of the Species Problem

Author: Jody Hey

In Genes, Categories and Species, Jody Hey provides an enlightening new solution to one of biology's most ironic and perplexing puzzles. When Darwin showed that life evolves, and that it does so by natural selection, he transformed our understanding of living things. But the very question Darwin addressed-the nature of species-continues to pose an awkward conundrum for biologists. Despite enormous efforts by a great many scholars, biologists still cannot agree on how to identify species or even how to define the word "species." Genes, Categories, and Species is not like other books on the species problem, for it does not begin by asking, "What is a species?" Instead, it focuses on the very fact that biologists are stumped by species and their curious behavior in coping with that uncertainty. Faced with a persistent conundrum-and no lack of data on the subject-biologists who ponder the species problem have ceased to ask the most essential of scientific questions: "What new information do we need to resolve the problem?" This is the question that motivates this book and leads to the discoveries it reveals. The answer to the species problem lies not with the processes and patterns of biological diversity, Hey contends, but rather in the way the human mind perceives and categorizes that diversity. The promise of this book is twofold. First, it allows biologists to understand the causes of the species problem and to use this knowledge to avoid the major confusions that arise over species. Second, with its explanation of the species problem, it gives scholars and students of human nature a humbling example of how ill-suited the human mind is for certain kinds of scientific questions.

Wussten Sie, dass Sie mit einem Röhrling näher verwandt sind als mit einem Gänseblümchen oder Vögel den Krokodilen näher sind als Eidechsen? In den letzten 30 Jahren sind die Methoden der Klassifikation des Lebens völlig neu überdacht worden. Das Resultat stellt die bisherige Einteilung der mehr als 2 Millionen bekannten Arten auf den Kopf. Das Buch hilft, die organismische Vielfalt zu bewältigen, indem wesentliche Einteilungs- und Ordnungskriterien vorgestellt und bedeutende stammesgeschichtliche Entwicklungslinien diskutiert werden.

What is evolution? What is a gene? How did these concepts originate and how did they develop? This book is a short history ranging from Lamarck and Darwin to DNA and the Human Genome Project, exploring the conceptual oppositions, techniques, institutional conditions and controversies that have shaped the development of biology.

Shaping Science with Rhetoric

The Cases of Dobzhansky, Schrodinger, and Wilson

Author: Leah Ceccarelli

Publisher: University of Chicago Press

How do scientists persuade colleagues from diverse fields to cross the disciplinary divide, risking their careers in new interdisciplinary research programs? Why do some attempts to inspire such research win widespread acclaim and support, while others do not? In Shaping Science with Rhetoric, Leah Ceccarelli addresses such questions through close readings of three scientific monographs in their historical contexts—Theodosius Dobzhansky's Genetics and the Origin of Species (1937), which inspired the "modern synthesis" of evolutionary biology; Erwin Schrödinger's What Is Life? (1944), which catalyzed the field of molecular biology; and Edward O. Wilson's Consilience (1998), a so far not entirely successful attempt to unite the social and biological sciences. She examines the rhetorical strategies used in each book and evaluates which worked best, based on the reviews and scientific papers that followed in their wake. Ceccarelli's work will be important for anyone interested in how interdisciplinary fields are formed, from historians and rhetoricians of science to scientists themselves.

Darwin's Ghost : The Origin of Species Updated

Author: Steve Jones

Publisher: Anchor Canada

ISBN: 9780385658676

Category: Evolution (Biology)

Page: 416

In Darwin's Ghost, Steve Jones has taken on the exciting challenge of rewriting the book of the millennium: Charles Darwin's The Origin of Species. Before The Origin, biology was a set of unconnected facts, but Darwin made it into a science, linked by the theory of evolution (the grammar of the living world). Darwin used the biology of the nineteenth century to prove his theory. Now, using the astonishing advances of the twentieth century, Steve Jones reargues the case. His "new version" of The Origin is a bold and fascinating tour of evolution's wonders, revealing ties between cancer and the genetics of fish, between brewing beer and inheriting disease, between the sex lives of crocodiles and the politics of Brazil.

Eine kurze Geschichte der Menschheit

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.

Charles Darwin's On the Origin of Species, in which he writes of his theories of evolution by natural selection, is one of the most important works of scientific study ever published. This unabridged edition also includes a rich selection of primary source material: substantial selections from Darwin's other works (Autobiography, notebooks, letters, Voyage of the Beagle, and The Descent of Man) and selections from Darwin's sources and contemporaries (excerpts from Genesis, Paley, Lamarck, Spencer, Lyell, Malthus, Huxley, and Wallace).
