Urvögel der Kreidezeit: Wie aus Dinosauriern Herrscher der Lüfte wurden

Fossil discoveries from around the world allow scientists to precisely study the more than 11,000 bird species existing today and their evolutionary roots. The evolutionary lineage of these animals stretches back some 150 million years to the age of the dinosaurs. State-of-the-art three-dimensional CT scans and behavioral studies of young birds are gradually deciphering the transition from bipedal prehistoric predator to flying creature. The documentary reconstructs the development of specialized skeletal features such as the alula feathers and the sternal crest, using important sites like the Spanish archaeological site of Las Hoyas as examples. After the devastating asteroid impact 66 million years ago, the surviving, ground-nesting birds occupied new ecological niches and spread rapidly. Today, the remarkable intelligence of corvids and the anatomical diversity of global species bear witness to this ongoing triumph of evolution. ``` Subscribe to our channel so you don't miss any videos:    / @earthstoriesde   #naturedocumentary #documentary #earthstoriesgermany -- Topics in this video: ▼ 00:00 Intro 01:07 Cretaceous Birds: How Dinosaurs Became Rulers of the Skies 43:19 Outro -- The most breathtaking nature documentaries you've ever seen?
