Our relentless drive to create makes us unique among living creatures. What is special about the human brain that enables us to innovate? Why don't cows choreograph dances? Why don't squirrels build elevators to their treetops? Weaving together the arts and sciences, neuroscientist David Eagleman and composer Anthony Brandt explore the need for novelty, the simulation of possible futures, and the social components that drive the inventiveness of our species. How humna creativity remakes the world.
