Research assessment
statement
Recurrent highland-lowland social networks moved crops through the Tien Shan and Pamir-Alay before any historically documented Silk Road.mechanisms
- Seeds, cultivation knowledge and food moved through repeated household exchange, seasonal mobility and intermarriage across mountain valleys.
chronology test
Directly dated crop finds should appear at multiple ecological steps rather than only along one linear path.geography test
Local processing evidence should follow initial crop appearances where cultivation was adopted.supporting evidence
- Directly dated millet at Surungur
- Local crop processing and cultivation at Tasbas
- Long-term exchange evidence at Begash
important caveat
Chronological and geographic overlap are necessary but not sufficient for causation.Research description
Chronological and geographic overlap are necessary but not sufficient for causation.
