One of the most fascinating questions we can ask is about what our world looked like before man arrived on the scene. With a lifespan dating back more than four billion years, finding answers to those questions about earth are not easy.
That is why science plays such a critical role in helping humans understand what came before us.

Our guest is Erik Gulbranson, an assistant professor of geosciences at UWM who helped find evidence that trees once grew where glaciers now dominate the landscape.
