Where does language come from?

A language that was spoken thousands of years ago eventually morphed into nearly all of the languages spoken today in the West. Science writer Laura Spinney joins host Krys Boyd to discuss the proto-Indo-European language, how it connects languages as varied as English and Russian, and how researchers study ancient language with no written texts to guide them. Her book is “Proto: How One Ancient Language Went Global.” This episode originally aired, July 22nd, 2026.
