Half of All Languages Come From This One Root Tongue. Here’s How it Conquered the Earth.
What do Spanish, Hindi and English all have in common? They all descended from the same mother tongue: Anatolian, or more commonly Proto-Indo-European.
In fact, there's about a 50 percent chance that any given person speaks a language from the Indo-European family, as Shoaib Daniyal recently reported for Quartz. Indo-European languages, a family that includes about half the languages spoken today. But there are still a lot of questions about who founded that original tongue, and when, and how it spread. Linguists do know that Proto-Indo-European was a language unique to a tribal culture in ancient Eurasia. They know that these ancient humans only spoke their language, they never wrote it down, and today it's extinct. (Of course, that hasn't stopped linguists from trying to reconstruct the language.) But they don't know exactly when and where the language truly began, or how it came to birth so many of our modern tongues.
