Chimps on Death Row

Dinosaurs in Your Garden

Horizon tells the story of maverick scientist John Ostrom and his theory that birds are really just dinosaurs with feathers. Thirty years later, a revolution in palaeontology has proven him correct. Horizon looks at the compelling and recent evidence that shows how modern birds fine-tuned their unique design for flight. It also confirms that Velociraptor dinosaur is more closely related to the sparrow than it is to the crocodile.
