Identification of domestic chicken bones in archaeological sites

Abstract In recent years, with the participation of genetics and other disciplines, the controversy on the origins of the domestic chicken has returned. As the resource of primary data, archaeology plays an extremely important role in this dispute. Taking an archaeological standpoint, this paper aims to establish a set of bone morphological identification standards for domestic chicken bones unearthed at archaeological remains, beginning with the bone morphology as the most basic but also the least studied aspect. By this set of standards, we reanalyze available chicken bone materials and relevant pictorial and textual materials for domestic chicken candidate samples as mentioned by previous scholars. The results show that no confirmed domestic chicken bones have been found in China’s early to mid-Holocene remains to date; meanwhile, there is no substantial archaeological evidence to support China as the earliest place of origin of domestic chicken. Future work seeking to advance research on the origin of the domestic chicken should first pay proper attention to the archaeological background; only continuing scientific analyses and exploration on the origin of domestic chicken based on scientific morphological identification will prove the most convincing methodology.
