Biological Anthropology
Outline Activities
I have been continuing research on Paleoamericans in North America and South America and their relationships with the Asian continent, such as the Jomon people. I am also working on testing evolutionary mechanisms for patterns of craniofacial morphology in order to distinguish between neutral forces and selective forces of evolution. This year, I start working on investigating ecogeographic significance of human postcranial diversity using postcranial bones in Bergmann’s and Allen’s perspective. I also explore the issue of race and gender in the history of biological anthropology in general and in Japanese physical anthropology in particular. Believing that scientific biases through the history of physical anthropology were always influenced by and supportive of political ideologies, I strongly feel the necessity to discern and reexamine anthropological theorizing related to problematic issues such as racism, nationalism, imperialism, and sexism.

  • A.We set out to test whether craniofacial morphology is simply an artifact of neutral genetic processes or is affected by differences in climate.
    Are the observed cranial patterns:
    1. Due to natural selection and shaped by differences in climate?
    2. Due to neutral processes (i.e., drift)?
    3. Due to gene flow?
    4. Test “isolation by distance” model
    5. Provide a framework for distinguishing between neutral forces and selective forces (natural selection) of evolution.
    6. Guide to improve our use of quantitative craniofacial traits for reconstructing population history and phylogeny.

    B. A study of postcranial indices, ratios and body mass versus eco-geographical variables in an assessment of phenotypic adaptation to climatic conditions.

Current and Past Project
  • Advances in three-dimensional technology have impacted the field of biological anthropology, archaeology, and the use of geometric morphometrics. This book explores a best-practices data acquisition method for recording landmark and semi-landmark data on fragile archaeological human remains.
    As a handbook to the collection and processing of 3-D scanned data, this book will be a tool for scholars interested in pursuing research projects with 3-D models. The chapters will enhance the reader’s understanding of the technology with consideration of virtual model processing protocols, alignment methods, introduction to actual data acquisition techniques, basic technological protocols, and consideration of variation in research design as associated with biological anthropology and archaeology.
  • Recent advancements in three-dimensional technology have impacted the field of biological anthropology and the use of geometric morphometrics. Three-dimensional digitizers such as Microscribe serve as excellent tools for collecting landmark and semi-landmark data. However, Microscribe requires direct access to skeletal materials, which is a problem on several levels. For instance, recording semi-landmark data over curved areas of bone can compromise poorly preserved specimens. Additionally, access to archaeological skeletal collections can often be impeded by restrictions mandated by the curation authority. This project explores a best-practices data acquisition method for recording semi-landmark data on fragile archaeological human remains, with a case study centered on Japan.

    For this purpose, we chose the curvature of the maxillary alveolar process as well as traditional craniofacial landmarks. Curve data were taken from 3D virtual cr anial models from three collections spanning historical and modern population samples from Japan using Stratovan Checkpoint software. For comparison, we collected 3D coordinate data on modern Japanese skulls using a Microscribe digitizer.

    Our study incorporates an assessment of the validity of landmark data acquired by Microscribe versus Checkpoint software. However, considering the difficulties of direct collection of curve data, using the Microscribe on actual skulls can present challenges.

    We demonstrate the process of acquiring curve data on virtual cranial models by using Checkpoint software, which improves data quality and benefits research by: 1) improving accuracy when identifying landmarks corresponding to maximum width and length; and 2) visualizing curve data allows for the determination of data quality and necessary adjustments.

9. In 1996, one of the oldest and best-preserved human skeletons in the United States was discovered on the banks of the Columbia River near Kennewick in the State of Washington, and has come to be known as Kennewick Man. In this paper, the origins of the 9,300 year old Kennewick individual and his early Holocene contemporaries in the Americas are explored. The results of our craniofacial metric analysis indicate that Kennewick Man shows a greater similarity with the Ainu, the prehistoric Jomon of Japan, and Polynesians, than with any other human samples in the world. The Jomon samples that show similarity with Kennewick Man are also similar to prehistoric inhabitants of the North American Northwest coast, Paleoamerican samples from Brazil, and the indigenous peoples of the southern end of South America. These results suggest that the ancestor of the Jomon in the Late Pleistocene of the northeast and eastern coast of Asia might be an important source for the first known inhabitants of the western hemisphere and might have migrated to North America and dispersed to South America..
