What is this episode about?

Paleontologist Steve Brusatte explains that birds are the only surviving lineage of dinosaurs, having evolved from small, feathered ancestors that endured the mass extinction 66 million years ago. While T-Rex and other giants succumbed to the asteroid's aftermath, these resilient, seed-eating avian ancestors adapted, eventually diversifying into the 10,000+ species we see today.
