The early adoption of East Asian crops in West Asia: rice and broomcorn millet in northern Iran

Following their early domestication, broomcorn millet and rice (in East Asia) wheat barley South-west were subsequently adopted across Eurasia during the Bronze Age/early historic period. The precise timing dispersal routes for this trans-Eurasian exchange, however, remain unclear. Here, authors present archaeobotanical evidence from sites on Caspian Sea's southern coast, demonstrating that reached West Asia by c . 2050 BC 120 BC. These dispersals relate to two waves of globalisation based different mechanisms: an ‘infiltration’ model (broomcorn millet) a ‘leapfrog’ (rice). results contribute our understanding continental-scale connectivity late prehistoric/early periods.
