This show is a Halloween treat. UC Davis instructor Sarah Juliet Lauro (pictured), who co-edited the new book "Better off Dead: The Evolution of the Zombie as Post-Human," appears on Davisville this week to talk about the book, zombies, how she got interested in zombies, what our interest in zombies says about our culture – and why she came to UC Davis to get her PhD in English. The book’s essays range in tone from seriously scholarly to accessible for non-academics. The chapters discuss zombies in old radio shows, zombies in movies, public zombie walks, the evolution of zombies (there are nine types), the origin of zombies – unlike Frankenstein and Dracula, for instance, they did not originate in Europe. If you tune in, you’ll learn why.
