Scientist and conservationist Wallace J. Nichols, also a 1989 DePauw University graduate, gives the principal address Sunday during DePauw's 171st commencement ceremony. Nichols gave his "sea turtle speech" in nearly 90-degree weather to 485 graduates. He told the group to be both lovers and fighters in life -- to love their families and blue planet and fight for their passions. Dr. Nichols along with Brian Lamb, chief executive officer of C-SPAN, received honorary doctoral degrees at the ceremony.
Phillip Bane steps off the platform Sunday with his diploma during the ceremony.
