Mass Extinctions: A Brief History of Life's Worst Moments

THU, FEB 26, 2015 (54:49)

Life on Earth has experienced at least five major events we call “mass extinctions,” during which a huge number of species have gone extinct in a short period of time. In this talk, paleontologist Phoebe Cohen will explore how scientists decide which extinctions get to be considered “mass,” the ways in which these events have reshaped life as we know it, and how a deep understanding of past extinctions can help us see the future.
