Draghi, ciclopi, giganti, unicorni, fenici. Quando gli antichi si imbattevano in resti di animali sconosciuti, subito li attribuivano a creature fantastiche. Poi gli scienziati hanno dimostrato che si trattava solo di fantasie ancestrali: i mostri non esistono, oggi lo sappiamo tutti; eppure la spiegazione che gli studiosi hanno dato di quei reperti è stata addirittura più terrificante: prima di noi, una miriade di altri viventi abitava il nostro pianeta, ma ora non ci sono più. Sulla Terra, infatti, nulla è per sempre.

Alla luce delle ricerche più recenti, l'audiolibro introduce i fondamenti della teoria evoluzionistica - formulata da Charles Darwin più di un secolo e mezzo fa - al cui centro stanno tre spinte concomitanti: le sorgenti di variazione, la trasmissibilità di una parte di questa variazione di generazione in generazione, l'azione della selezione naturale nei mutevoli contesti ecologici. Ripercorre poi gli altri meccanismi che oggi integrano ed estendono il nucleo darwiniano della teoria, fino alla comparsa di Homo sapiens, un ramoscello nel ricco "cespuglio" degli ominini.

Una storia prima della storia. Ossa fossili, denti, manufatti, siti preistorici e dati genetici per ricostruire l'evoluzione di un gruppo di scimmie antropomorfe che, intorno a 6 milioni di anni fa, in Africa, intrapresero l'intricato percorso evolutivo che diede origine alla nostra specie.

Why is the genome of a salamander 40 times larger than that of a human? Why does the avocado tree produce a million flowers and only a hundred fruits? Why, in short, is there so much waste in nature? In this lively and wide-ranging meditation on the curious accidents and unexpected detours on the path of life, Daniel Milo argues that we ask these questions because we’ve embraced a faulty conception of how evolution - and human society - really works.

In The Synthetic Age, Christopher Preston argues that what is most startling about this coming epoch is not only how much impact humans have had but, more important, how much deliberate shaping they will start to do. Emerging technologies promise to give us the power to take over some of Nature's most basic operations. It is not just that we are exiting the Holocene and entering the Anthropocene; it is that we are leaving behind the time in which planetary change is just the unintended consequence of unbridled industrialism.

In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed - a toxic plant named for the sticky white substance emitted when its leaves are damaged - and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species.

From star-nosed moles that have super-sensing snouts to electric eels that paralyze their prey, animals possess unique and extraordinary abilities. In Great Adaptations, Kenneth Catania presents an entertaining and engaging look at some of nature's most remarkable creatures. Telling the story of his biological detective work, Catania sheds light on the mysteries behind the behaviors of tentacled snakes, tiny shrews, zombie-making wasps, and more.

In the new essays collected here, an interdisciplinary group of scholars asks age-old questions about the nature and well-being of humans in the context of a revolutionary new biotechnology - one that has the potential to change the genetic make-up of both existing people and future generations. Welcoming listeners who study related issues and those not yet familiar with the formal study of bioethics, the authors of these essays open up a conversation about the ethics of gene editing.

Brains Through Time examines how vertebrate nervous systems evolved in conjunction with other organ systems and the planet's ecology. Surveying an enormous range of information on genes and proteins, sensory and motor systems, central neural circuits, physiology, and animal behavior, the authors reconstruct the major changes that occurred as vertebrates emerged and then diversified.

Dieses Hörbuch ist eines über die Ansichten eines Vernunftmenschen und Forschers aus Leidenschaft. Die Rede ist von Richard Dawkins - Evolutionsbiologe, Aufklärer und Religionskritiker. Richard Dawkins ist einer der einflussreichsten gegenwärtigen Intellektuellen. Mit dem Erscheinen seines Bestsellers "Der Gotteswahn" wurde Dawkins einer großen Öffentlichkeit als vehementer Religionskritiker bekannt. Seither gilt er als einer der bekanntesten Vertreter des sog.

How to Keep Dinosaurs is a best-selling guide, packed with the sort of information keen dinosaur keepers crave - from feeding and housing to curing common ailments, breeding and showing your animal. The author, a zoologist with extensive experience of dinosaurs, has provided a timely and much-needed source book for all those who keep dinosaurs and for the huge numbers who are contemplating getting one. It is as essential to every dinosaur keeper as a stout shovel and a tranquilliser rifle.

For the last three billion years or so, life on Earth was shaped by natural forces. Evolution tended to happen slowly, with species crafted across millennia. Then, a few hundred thousand years ago, along came a bolshie, big-brained, bipedal primate we now call Homo sapiens, and with that, the Earth’s natural history came to an abrupt end. We are now living through the post-natural phase, where humans have become the leading force shaping evolution. This audiobook considers the many ways that we’ve altered the DNA of living things and changed the fate of life on earth.

El origen de las especies es un libro de Charles Darwin publicado el 24 de noviembre de 1859, considerado uno de los trabajos precursores de la literatura científica y el fundamento de la teoría de la biología evolutiva. Presentó pruebas de que la diversidad de la vida surgió de la descendencia común a través de un patrón ramificado de evolución. Darwin incluyó las pruebas que reunió en su expedición en el viaje del Beagle en la década de 1830 y sus descubrimientos posteriores mediante la investigación, la correspondencia y la experimentación.

Offering a bold new understanding of who we are, where we came from, and where we are going, noted ecologist Mark Bertness argues that human beings and their civilization are the products of the same self-organization, evolutionary adaptation, and natural selection processes that have created all other life on Earth. Bertness follows the evolutionary process from the primordial soup of two billion years ago through today, exploring the ways opposing forces of competition and cooperation have led to current assemblages of people, animals, and plants.

Nature, it has been said, invites us to eat by appetite and rewards by flavor. But what exactly are flavors? Why are some so pleasing while others are not? Delicious is a supremely entertaining foray into the heart of such questions. With generous helpings of warmth and wit, Rob Dunn and Monica Sanchez offer bold new perspectives on why food is enjoyable and how the pursuit of delicious flavors has guided the course of human history.

The Fool and the Heretic is a deeply personal story told by two respected scientists who hold opposing views on the topic of origins, share a common faith in Jesus Christ, and began a sometimes-painful journey to explore how they can remain in Christian fellowship when each thinks the other is...

This Very Short Introduction uncovers the history of our understanding of sexual selection, from Darwin's key insights to the modern day. Considering the investment animals place on reproduction, variation in mating systems, sexual conflict, and the origin of sexual dimorphism, authors Marlene Zuk and Leigh Simmons discuss questions such as whether females can really choose between males on aesthetic grounds and how sexual conflict is resolved in different species.

The Mesozoic Era, which lasted from about 252 to 66 million years ago, is divided into three periods, the Triassic, Jurassic, and Cretaceous. During this era, one type of life came to dominate the planet more completely and for a longer period than had been seen before or since; this was the Age of Reptiles. Beginning in the Triassic but especially in the Jurassic period, reptiles came to dominate the oceans, the land and even the skies.
