The Extinction of Mammoths (39:52)

Guest: Todd Surovell, PhD, Professor of Anthropology at the University of Wyoming  Why aren’t there any mammoths wandering the earth today? The ancient, elephant-like beasts have been extinct for tens of thousands of years. Theoretical explanations include a meteor, an earthquake or a heatwave.   Research coming out of the University of Wyoming claims to prove that we humans are the culprit.
