Publisher's Synopsis
"Birds and dinosaurs have dominated human interest for decades. In this well-supported revolutionary view of the field, critical questions are explored with credible evidence and biological thought. Are birds derived directly from advanced dinosaurs, or are they closely related dinosaur cousins? Did flight originate via the natural "gravity-assisted" trees-down model, or from the improbable "gravity-resisted" ground-up model? Were the earliest birds ground-predators or trunk-climbing gliders? Were dinosaurs hot-blooded with insulating protofeathers, or highly active, cold-blooded reptiles?
