A few years after the publication of Charles Darwin's The Origin of the Species, the scientific world was set aflutter by an amazing discovery: a fossil skeleton exquisitely preserved, even to the impressions of individual feathers on its wings, had been found in the Bavarian region of Germany. Researchers determined that the unique coupling of its avian feathers and reptilian toothy skull offered tangible proof of the theory of evolution. Hailed as First Bird, archaeopteryx became a celebrity among fossils, and the subject of heated debates. Are birds actually living dinosaurs? Where does the fossil record actually lead? This volume is a piece of detective work, exploring how the thinking about the mysteries of flight has developed.
