Using robots to study evolution, the last installment of our series of books on a future to look forward to, and did reintroducing wolves really restore an ecosystem? First up this week, a new study of an iconic ecosystem doesn’t support the “landscape of fear” concept. This is the idea that bringing back apex predators has a huge impact on the behavior of their prey, eventually altering the rest of the ecosystem. Host Sarah Crespi talks with Contributing Correspondent Virginia Morell about the findings. Next, using bioinspired robotics to explore deep time. Michael Ishida, a postdoctoral researcher in the Bio-Inspired Robotics Lab at the University of Cambridge, talks about studying key moments in evolutionary history, such as the transition from water to land by creating robotic versions of extinct creatures. Finally in the last in our series of books on an optimistic future, books host Angela Saini talks with Ruha Benjamin, a professor of African American studies at Princeton University and recently named MacArthur Fellow. The two discuss Benjamin’s latest book, Imagination: A Manifesto, which explores the part that imagination plays in creating new and radical futures.
