At a Zocalo Public Square event at the Skirball Cultural Center, Arizona State University President Michael Crow and Dr. Siddhartha Mukherjee—author of the new book The Gene: An Intimate History and the Pulitzer Prize-winning The Emperor of All Maladies: A Biography of Cancer—explored how what it means to be a human being is changing, both biologically and culturally. They wrestled with questions about how our increasing knowledge of genetics and our ability to manipulate our genes are altering notions of who we are, and posing new questions that require new language and new regulations to answer.
