On my latest podcast, I talk to Charles Ofria, a computer scientist who helped build Avida, one of the most intriguing examples of artificial life around. I wrote about Avida when it first hit the news back in 2005 in this cover story for Discover. Five years on, I caught up with Ofria for the podcast. I learned that the Avidians are evolving to be cleverer and cleverer–clever enough, in fact, to control robots. When they show up in my town, I plan on waving the magazine cover so they’ll spare me. Check it out.
