  • Investigating intentional cranial modification: A hybridized two-dimensional/three-dimensional study of the Hirota site, Tanegashima, Japan Reviewed

    <jats:p>Intentional cranial modification has a long history, being a ubiquitous practice in many cultures around the world for millennia. The crania excavated at the Hirota site on Tanegashima Island, Kagoshima Prefecture, Japan, has been previously noted to have a marked tendency toward a short head and a flattened occipital bone, which has been suggested to be the result of artificial cranial deformation. However, whether this deformation was intentional or caused by unintentional habits remains unclear. This study aimed to investigate the characteristics of the cranial shape of the Hirota site to clarify whether the crania were intentionally modified. In the examination of Hirota crania, Kyushu Island Jomon and Doigahama Yayoi crania were added as comparative data and contrasted with three-dimensional (3D) surface scan imaging and two-dimensional outline-based geometric morphometric analysis, combined with objective assessments of potential cranial modification. The results showcased Hirota’s short and flattened cranial morphology, indicating clear alignment with our hypothesis that Hirota samples are morphologically different from Doigahama and Jomon samples. No sex-based differences were found. Morphological abnormalities in cranial sutures were visually assessed utilizing novel 3D visualization methods of cranial outer surfaces. Based on a comprehensive review of the results, we concluded that Hirota site crania were intentionally modified. Although the motivation of the practice is unclear, the Hirota people may have deformed their crania to preserve group identity and possibly aid in the long-distance trade of shellfish, as seen archaeologically.</jats:p>

  • Reexamining Ceramic Standardization During Agricultural Transition: A Geometric Morphometric Investigation of Initial – Early Yayoi Earthenware, Japan Reviewed

    <jats:title>Abstract</jats:title>
    <jats:p>The quantifiable and reproducible representation of variability in material culture has continued to play a key role in the elucidation of shifting patterns of production organization in prehistoric archaeology. The study of standardization of ceramics has traditionally illuminated on how agents shift means of production to a common goal. However, while geometric morphometric (GMM) approaches to standardization quantification overcome issues of reproducibility faced in traditional literature, the lack of widespread radiocarbon dating in Japan requires adherence to traditional methods of temporal control. This study seeks to extrapolate ceramic standardization in a quantifiable means, while also maintaining temporal control utilizing traditional methods. In a pilot case study of the agricultural transition period of the Yayoi period of the Japanese peninsula (∼900/800 BC–300 BC), results of mortuary vessels show that while a previous model based on visually determined traditional methods assumed that ceramic manufacture was centralized in the Hakata Bay subregion of the northern Kyushu island region; utilizing GMM analysis to extrapolate variable standardization is able to identify a decline in morphological variation, despite increases in population density and potential variability between migrant and indigenous production patterns. These results further illuminate the strong correlation between production intensity and its effect on standardization practices in material culture production, as seen in modern ethnoarchaeological literature.</jats:p>
