On the Wing is the first book to take a comprehensive look at the evolution of flight in all four groups of powered flyers: insects, pterosaurs, birds and bats. David Alexander describes and evaluates both traditional and modern wing-origin theories in light of new fossil and genetic evidence.

Pourquoi les oiseaux ont-ils des ailes ? Pour voler, bien sûr ! Oui, mais, à quoi sert de voler ? Et si c'est aussi formidable que ça, pourquoi certains oiseaux ont-ils perdu leur capacité au vol, comme les autruches ou les émeus ? Quel a été le plus grand dinosaure volant ? À quoi ressemblerait un ange ou une fée si ces créatures fantastiques existaient vraiment ? Est-ce que les hommes ont copié les animaux pour construire leurs machines volantes, ballons, avions, capsules spatiales ? Bref, comment l'évolution d'un côté et l'humanité de l'autre ont-ils procédé pour vaincre la pesanteur et aller toujours plus haut dans le ciel ? C'est à toutes ces questions, et à beaucoup d'autres encore, que ce merveilleux livre répond. Vous y découvrirez des écureuils qui planent, des machines géniales qui n'ont jamais décollé du sol, des orchidées qui ont conclu un marché avec des papillons de nuit, et tant d'autres surprises ! Avec Richard Dawkins, le rêve et la science ne se sont jamais si bien accordés.

From airplanes to birds, the phenomenon of flight has always amazed and mystified humans. Therefore, it is unsurprising that scientists have invested a substantial amount of research into unraveling the secrets of flight evolution. Over the course of the past decade, the science of flight evolution has recently experienced a research renaissance, most of the information has been confined to the ivory tower of academia. In On the Wing, David Alexander delves into the evolution of flight in each of the four animal groups that evolved powered flight: insects, pterosaurs, birds, and bats. Alexander presents and compares each group's evolutionary history, including diversification and partial or complete extinction, especially as related to flight. The evolution of flight in animals is fascinating story riddled with scientific controversy and colorful characters, from the incredible Archaeopteryx to the recently-discovered feathered dinosaur Microraptor. Chapter topics include aerodynamics, comparisons and contrasts among the powered flyers, and the ultimate evolution away from flight. Alexander even examines the surprisingly diverse group of gliding animals, including squirrels, snakes, and ants. Through rigorous yet accessible writing, Alexander offers a comprehensive and engaging account of the evolution of flight, from dinosaurs to modern birds. On the Wing will delight and inform everyone from bird lovers to dinosaur enthusiasts, and offers key insights into the perpetual mystery of flight. -- Provided by publisher.

This book will take you on an exciting journey made up of texts and images. Spectacular, large-scale photographs printed on double pages and accompanied by explanatory texts will arouse the reader’s curiosity about evolution’s accomplishments in the world of flying: from the botanical air fleet (pollen grains, flying seeds…), over flying snakes and fish, to penguins flying underwater and humans rising into the air. Mathematician and passionate animal photographer Georg Glaser has joined forces with the experienced evolutionary biologist Hannes Paulus and the exercise physiologist and flight biophysicist Werner Nachtigall in order to approach this topic with words and pictures in a way that is both generally comprehensible and scientifically sound. Double-page by double-page, the book can be read in any order. Cross-references allow to jump easily from one double-page to another. Aside from the detailed introduction to each chapter, the text passages are usually independent from one another, and they discuss crucial moments in the evolutionary process. The double-pages provide additional information on bibliographical references and references to informative websites.
