I just listened to this interview:
On the evolution of feathers
"There's great evidence now for feathers evolving in the theropods [meat-eating dinosaurs including Tyrannosaurus rex]. And these creatures were primarily runners — they had long, strong, overdeveloped, marathon-runner legs, and walked on two legs and ran on two legs, which freed up their arms, perhaps, by one of the theories, to be feathered and used eventually for flight. But one thing that we really believe now about the evolution of feathers is that the simplest feathers — the first feathers in the series of steps toward building a complex vein feather — were not aerodynamic. So the first uses of feathers must have been for other purposes."
