David Attenborough embarks on an extraordinary journey to unravel one of Nature's most gripping stories - the evolution of flying animals. The power of flight is one of the greatest miracles of Nature. Over one hundred billion creatures soar through the air today - from nectar-drinking hummingbirds to armoured airborne beetles, from bats hunting in the black of night to bizarre winged lizards. In 'Conquest of the Skies', David Attenborough travels back in time to unravel the astonishing 300-million-year story of how these animals first appeared and then evolved into the huge variety of aeronauts that fill our skies today. Only now, using the latest scientific analysis, can he reveal the hidden mechanics behind their gravity-defying skills. The multiple BAFTA-winning production team used ground-breaking 3D cameras, high-speed filming and stunning CGI to bring the viewer closer than ever before to this astounding aerial world. From the steaming rainfofests of Borneo to the frozen fossil beds of China, the arid canyons of Spain to the cloud forests of Ecuador, this series spans the globe to explore the thrilling and surprising story of how the flying animals came to conquer the skies.
