New language database narrows search for first speakers of Indo-European.

The article focuses on a new study addressing the origins and spread of the Indo-European language family, spoken by over 3 billion people today. Using the largest reliable database of Indo-European basic vocabulary compiled by a team of experts, the study proposes a hybrid origin for Proto-Indo-European (PIE): it first emerged with early farmers in the Fertile Crescent over 8,000 years ago and later spread across the Eurasian steppe via nomadic herders around 6,500 years ago. While the study offers a refined linguistic family tree and timeline, some scholars remain skeptical, noting inconsistencies and emphasizing that archaeological and genetic evidence still supports the steppe as a key region for Indo-European expansion. The research provides a significant resource for future investigations but does not fully resolve longstanding debates about PIE's origins.
