Could PIE have developed initially in Anatolia, subsequently acquired by the Yamanaya, and spread by them with the wheel and the horse?
Were there any other factors that contributed to the spread of PIE?
Yes, the development of wheeled vehicles also played a significant role in the spread of PIE. Wheeled vehicles allowed for faster and more efficient transportation of goods and people, which facilitated the spread of culture and language across different regions.
