A groundbreaking study using ancient DNA extracted from textile fragments has identified the 'Wool Road', a specialized trade network that operated across the Altai Mountains as early as 1,000 BCE. By tracing the genetic lineage of sheep wool found in Scythian burials, researchers discovered that elite garments were crafted from fibers imported from as far as the Tibetan Plateau and the Iranian Highlands, indicating a highly sophisticated market for luxury textiles.
The findings challenge the traditional view of the Silk Road as a singular east-west corridor, suggesting instead a complex web of vertical trade between high-altitude pastoralists and lowland urban centers. This network facilitated not only the exchange of goods but also the spread of weaving technologies and dyeing techniques, such as the use of rare insects for crimson pigments, which became status symbols across Eurasia long before the Han Dynasty expanded westward.
