How could we have lived so long in perfect ignorance of that astonishing fact? "The researchers travelled to China in 2012 to study fossils of feathered dinosaurs from the Cretaceous era."

that's how knowledge is routinely gained in science, in small incremental verifiable steps...the eureka moment the layman expects of scientific discoveries rarely happens...
