Silurian Hypothesis

How Has Industrial Society Affected the Planet? Guest: Adam Frank, Professor, Physics and Astronomy, University of Rochester The Silurian Hypothesis: Could Earth have been ruled by another advanced civilization millions of years ago, one constituted of lizard people, perhaps? That’s the clickbait. What the Silurian Hypothesis is really asking is how has our industry impacted the environment, and what our fossilized record would look like.  UFO Stories Guest: Sam Payne, host, "The Apple Seed," BYUradio Sam Payne shares a story from a childhood sleepover on a neighbor's trampoline when he thought he saw a UFO. He misses that kid who was so ready to believe. But, Marcus asks, where were the lizard people? From catastrophic asteroids to terminal constipation, how did the dinosaurs get wiped out? Guest: Mike Benton, Professor, Vertebrate Paleontology, University of Bristol Maybe we'll never know why the dinosaurs went extinct, but why we really should still care.
