Birds and Flight

Andy McIntosh

Andy McIntosh is a Professor of thermodynamics. In this talk he examines the structures that enable creatures to fly. He asks could these structures have arisen gradually by natural selection or do they make up a system, where each part is needed fully formed, before the others are of use? This talk starts by looking at bird navigation and ends by comparing the lungs of birds with those of dinosaurs. This is a fascinating exploration of flight.
