What Killed the Dinosaurs?

It is often difficult, sometimes impossible, to get a definitive answer to some of life's most enduring questions. Scientific processes provide alternative explanations for a wide variety of phenomena by piecing together all the available information. This interactive activity on the Evolution website explores four possible hypotheses to explain what caused the extinction of the dinosaurs 65 million years ago, inviting the viewer to consider the evidence and come to their own decision.
