A new paper published in the Proceedings of the National Academy of Sciences by UW researchers Bob Kelly, Todd Surovell, Bryan Shuman, and one-time UW graduate student Geoff Smith looks at climate change in the Bighorn Basin in Wyoming and how it affected the population living there over thousands of years. Archaeologist Todd Surovell and geologist Bryan Shuman came in to talk about their work with Wyoming Public Radio's Irina Zhorov.
