Why do some societies thrive while others fail? What makes certain societies more vengeful, more violent, or more war-driven than others? And what can we who live in the world's modern societies learn from those who dwell in -- or have dwelled in -- the world's traditional societies? Such are the questions we explore on this edition of StudioTulsa. Tomorrow night, Thursday the 26th, TU's Presidential Lecture Series will host an address by Jared Diamond, a leading scientist on the world stage as well as the author of the Pulitzer Prize-winning "Guns, Germs, and Steel: The Fates of Human Societies." This is address is free to the public, begins at 7:30pm, and will take place in the Donald W. Reynolds Center on the TU campus. Diamond, who is our guest on ST today -- and who is also the author of "The Third Chimpanzee: The Evolution and Future of the Human Animal," "Collapse: How Societies Choose to Fail or Succeed," and "The World Until Yesterday: What Can We Learn from Traditional Societies?" -- is a professor of geography at UCLA. (TU's Presidential Lecture Series is sponsored by the Darcy O'Brien Endowed Chair and is supported by the Office of the Provost. You can learn more about Diamond's upcoming address at TU here.)
