Take a journey through deep time as we explore a story that has taken millions of years to unfold, and then examine a brand new discovery! Where did life begin? How did the first four-footed land animals emerge? And why do fossil whales have feet? Participants examine the museum’s fossil whales and related species as they learn about the evolutionary processes responsible for the diversity of life on earth. After a brief presentation, visitors can make a cast of a tooth from an ancient whale species called Dorudon and help to construct an evolutionary timeline.
