"We know that almost everyone in Europe, the Middle East, and India speaks a language that is descended from a common root language: the Proto-Indo-European language, which was spoken by a single group, the Proto-Indo-Europeans, about eight thousand years ago. We believe these people lived in either Anatolia or the Eurasian Steppes-present day Turkey or southwestern Russia."
"In general we know the PIE were extremely advanced for their time-their use of horses, the wheel, tools, and agriculture made them a force in the region, and their descendants went on to dominate the world from Europe to India. As I said, today roughly half the world speaks a Proto-European language. In many ways, they are the ultimate lost civilization."
