Cellmates

There’s a black hole in the middle of the history of life: how did we go from tiny bags of chemicals to the vast menagerie of creatures we see around us?  Today, we explore one of the most underrated mysteries of all time, and present one possible answer that takes us from an unexpected houseguest to a tiny bolt of lightning to every critter you hold dear. It’s the story of one cosmic oops moment that changed the game of life forever.   Production help from Matt Kielty and Annie McEwen. Reporting help from Latif Nasser.
