Portraying the moderator of a debate among foes of Charles Darwin in "The Struggle for Existence: Darwin's Dreams" is actor Chris Harrison (left). Bishop Samuel Wilberforce (center), played by Residential College faculty member Fred Peters, asks, "Is it credible that a turnip strives to become a man?" while Professor Richard Owen (Michael Harrison) listens. The play was written by Catherine Badgley, research scientist in the Department of Geological Sciences and the Museum of Paleontology and a lecturer in the Residential College. The action of the play focuses on the weeks leading up to the publication of Darwin's major treatise on evolution, "The Origin of Species." (Photo by John Klausmeyer)
