"Tens of billions of birds share the planet with us, an astonishingly diverse array of species that are present nearly everywhere humans call home--and many places we do not. With their flamboyant plumage, joyous dawn serenades, extraordinary aerial feats, they have captivated human imagination for millennia. Undeniably delicate creatures with hollow bones and thin skin protected by downy feathers, how did such a seemingly fragile species break the bounds of Earth and begin to fly, how have they survived millennia, and how does their legacy shape our world? Hailed as 'one of the stars of modern paleontology' (National Geographic), Steve Brusatte now tells the extraordinary story of the dinosaurs' living legacy: birds. He begins by exploring how dinosaurs gradually developed the trademark features of birds one-by-one--feathers, wings, beaks, big brains, keen senses, and warm-blooded metabolisms. He investigates why birds where the only dinosaurs to survive the cataclysmic asteroid impact 66 million years ago and chronicles how these survivors rapidly proliferated to produce the diversity of avian species we know today"-- Provided by publisher.
