Blue Sky Science: How did animals evolve from water to land?
Blue Sky Science is a collaboration of the Wisconsin State Journal and the Morgridge Institute for Research. The questions are posed by visitors to Saturday Science events at the Discovery Building, a monthly series that features interactive exploration stations centered around a particular topic. The Blue Sky Science team then sets out to find an expert to answer the questions. To view other videos in the series, see http://go.madison.com/bluesky.
