Dr. Deborah Bolnick, genetic anthropologist and associate professor in UT’s Anthropology Department, visited the TARL Human Osteology collection with one of her doctoral students, Austin Reynolds, recently as they begin their identification of osteological elements for aDNA. Most interested in intact adult molar-dentition, which may provide the valuable genetic material for their testing, they made their way carefully through the collections and handled each element with great respect. The research that Dr. Bolnick and her student are working on (and more specifically, will publish on) will provide much needed insight into the genetic impact of the earliest Spanish colonial contact with Native Americans in Texas.
TARL has been very willing to work with Dr. Bolnick and her students for a number of reasons, not the least of which is her preference to attempt to obtain the necessary genetic material through a non-destructive technique involving a ‘bath’ for the element selected for aDNA sampling. Lead author on an article in the American Journal of Physical Anthropology published in 2012, the collaborative journal article describes this non-destructive process. You can find the article abstract at:
Nondestructive sampling of human skeletal remains yields ancient nuclear and mitochondrial DNA
Am J Phys Anthropol. 2012 Feb;147(2):293-300. doi: 10.1002/ajpa.21647. Epub 2011 Dec 20.
Dr. Bolnick is very aware of the sensitive nature of the collections she is accessing and utilizing in her research. She works with us to ensure that TARL as a UT research entity, and the collections she is working with specifically, are all compliant under NAGPRA laws and regulations. She has also made clear her willingness to discuss the nature and significance of her research with those Native American communities that have expressed interested in gaining this scientific perspective. Please follow the status of her projects and publications on our blog as she continues to work with TARL staff and collections, expanding our understanding of the prehistory of Texas and its early inhabitants. We look forward to her continuing research!
