Paleontology Concepts and Evolutionary Evidence

The video features a session with paleontologist Kirsten Formoso, who discusses her background, the formation of fossils, and how they help us understand past ecosystems. She explains the evolution of whales from land animals and birds from dinosaurs. The session includes a Q&A where Kirsten answers questions about her career and paleontology. The video concludes with information on how to follow Kirsten online.
