Seminar Lab Details: 

Summary: Most people know about the mass extinction that took out the dinosaurs 66 million years ago. However, a lot of people are unaware of the other significant mass extinction events in Earth's past that have shaped biological evolution. In this talk, I will cover the 5 largest mass extinctions of all time; specifically, what caused them, what effects they had on life, and what we can learn from them.
