Earth's six major mass extinctions: an introduction

About this course

The course surveys five prehistoric mass extinctions alongside the present-day Holocene Extinction Event, including the extinction of the dinosaurs, the Great Dying and the Ordovician-Silurian event. It considers possible causes for each period, while recognising that scientists have not reached complete explanations for all of them. Participants also examine how scientists date rocks and identify evidence for extinction events. Teaching combines presentation, discussion and materials for viewing, with attention to the fragility of ecosystems and how relatively small changes can cause disruption.

What you'll learn

• Identify the six major extinction events covered by the course
• Describe evidence used to investigate mass extinctions
• Explain possible mechanisms that contributed to particular extinction events
• Discuss the fragility of ecosystems across planetary history
