Founder and Executive director of the Edelman Fossil Park of Rowan University Paleontologist Dr. Kenneth Lacovara joins WIRED to answer the internet's questions about the phenomenon of extinction. How do we know an asteroid killed the dinosaurs? Where was the impact? Could humans go extinct in the same fashion? What are the five mass extinctions? Why are we trying to bring back extinct species, isn't it dangerous? Which species came closest to extinction but bounced back? Answers to these questions and plenty more await on Extinction Support.
