Explore the fascinating world of avian evolution in this 48-minute lecture by Dr. Corwin Sullivan from the University of Alberta. Delve into the groundbreaking discoveries from the Jehol and Yanliao Biotas in northeast China that revolutionized our understanding of bird origins, feather evolution, and the development of flight. Learn about the exceptional fossil preservation in these assemblages, which revealed primitive birds and closely related non-avian theropods with intact feathers and soft tissues. Examine the evidence supporting the theropod ancestry of birds, including the famous Archaeopteryx fossil. Investigate the diverse anatomical structures potentially related to flight in early birds and their close relatives. Gain insights into the initial purposes of feathers, such as display and insulation, before their adaptation for flight. Through this comprehensive exploration of Chinese fossil vertebrates, filamentous feathers, and wing reconstructions, develop a deeper appreciation for the complex evolutionary journey from dinosaurs to modern birds.
