Prehistoric wooden bows and arrows in the Turpan Basin,Northwest China: Wood selection and utilization in a mosaic landscape

In the present study, we analyzed seven wooden bows and 13 arrows excavated from the cemeteries of Subeixi Culture (13th century BCE–AD second century) in the Turpan Basin, northwest China. A total of six taxa, viz. Morus sp., Salix sp., Picea sp., Lonicera sp., Betula sp., and Tamarix sp. were identified. Some of these taxa have been generally accepted to be suitable for bow-and-arrow production. All these taxa were local in origin but distributed in different ecotonal zones, including oases, saline-alkali lands, and mountain areas. Previous archaeological studies have confirmed that the Subeixi populations lived an agro-pastoral life. By analyzing the possible provenance of these wood samples, it can be hypothesized that these ancient agro-pastoralists moved between the Turpan Basin and the Tianshan Mountains on a seasonal basis.     

The Archaic Period in the south-central Andes

Although the Archaic Period of the south-central Andes is not well-known beyond Latin America, there is much of interest in it to archaeologists working with foraging populations. Like the North American Archaic and European Mesolithic, the Archaic in the region is characterized by ethnic differentiation, changes in the scale and frequency of residential mobility, resource intensification and specialization, and population growth. The origin and evolutionary trajectory of these trends are discussed within the context of the development of ecological complementarity, a strategy of land use that exploits the vertically stratified distribution of resources in the Andean environment.
