How a single meteorite strike cleared the path for the rise of mammals
In short: Palaeontologist Simon Conway Morris examines the catastrophic extinction of the dinosaurs and the subsequent evolution of life. Recorded in 1996, this lecture uses fossils and demonstrations to illustrate how planetary collisions reshaped Earth's history and paved the way for modern mammals.
In this 1996 Royal Institution Christmas Lecture, Simon Conway Morris investigates the causes of mass extinctions, specifically focusing on the role of meteorite impacts. By analyzing fossils and skeletal remains, he traces how the disappearance of prehistoric giants allowed mammals to emerge and eventually flourish.
The lecture also explores the 1908 Tunguska event in Siberia as a case study for meteorite impacts. Conway Morris demonstrates the potential consequences of similar collisions occurring in populated areas like London or within the Atlantic Ocean, while also detailing how scientists use fossil evidence to map the history of life on Earth back over 3 billion years.
