Dinosaurs and Their Avian Descendants

Dino explains how dinosaurs, once thought extinct, have living descendants: birds. The video explores the extinction event 65 million years ago and how some dinosaurs survived due to their adaptations. These survivors evolved into birds, with evidence from theropods like velociraptors and T-rex. Over millions of years, bird-like traits developed, leading to the diverse bird species we see today. The video emphasizes that birds are not just descendants but are indeed living dinosaurs.
