Dinosaurs are not as extinct as we might have thought. The big ones didn't make it past the asteroid impact 65 million years ago. But some small flying ones did. Hence birds!
Connecting modern birds to ancient dinosaurs was a scientific detective story, and this episode of NOVA retraces the steps. And some of the best evidence is of recent discovery.
Birds have been on an evolutionary journey. A journey that included feathers, powered flight, and many extinctions.
Fossils reveal how birds survived the killer asteroid and became today’s only living dinosaurs. Contrary to popular belief, dinosaurs never went extinct. They’re still alive among us—in the form of birds! Birds are the only dinosaurs that survived the cataclysmic mass extinction caused by an asteroid the size of Mt. Everest crashing into Earth about 66 million years ago. The big question is: How? How did birds manage to not only live through the apocalypse, but also go on to diversify and populate every corner of our planet? Now, rare fossil discoveries are revealing the secrets of bird evolution going back more than 100 million years, telling the story of how some resilient feathered dinos persevered and transformed into the vast array of colorful bird species that fill our skies today.
