Gerta Keller Interview

For decades, we've been told the dinosaurs were wiped out by a single catastrophic asteroid impact — a story that has become almost mythic in its simplicity. But what if that isn't the full truth? In this episode, host Matt Crawford speaks with Professor Gerta Keller, one of the world's leading paleontologists and a bold voice challenging conventional science. Drawing on over 40 years of fieldwork and groundbreaking research, Keller's new book The Last Extinction: The Real Science Behind the Death of the Dinosaurs reexamines the evidence and makes a compelling case that massive volcanic eruptions — not just an asteroid — drove the greatest extinction in history. Together, they discuss scientific resistance, the importance of questioning accepted narratives, and what ancient mass extinctions can teach us about our own fragile planet today.
