In the high-tech space race to find intelligent life, it might be good to remember Darwin’s 19th century ideas when we’re up there. Arik Kershenbaum is a zoologist and fellow at Girton College, University of Cambridge. He joins host Krys Boyd to talk about understanding evolution on Earth and how that might parallel alien life forms elsewhere. His book is called “The Zoologist’s Guide to the Galaxy: What Animals on Earth Reveal about Aliens – and Ourselves.”
