Once thought impossible, new research suggests people can learn perfect pitch. University of Chicago paleontologist and science explainer extraordinaire Neil Shubin is back to discuss that, the unique way trap-jaw ants avoid predators, “virgin births” in sawfish, and the shrinking of Mount Everest.
