Final answer:
Mary is most likely a biological anthropologist who specializes in anthropological archaeology, focusing on the excavation and analysis of ancient Mayan artifacts, which helps understand past human societies and their cultures.
Step-by-step explanation:
Mary is an anthropologist who works in Belize, excavating and analyzing ancient Mayan artifacts. Given her engagement in the excavation and analysis of physical remains, she is most likely a biological anthropologist, specializing in the subfield of anthropological archaeology. Biological anthropologists are primarily interested in the biological development of humans over time and may focus on the emergence of culture as part of human evolution. Similarly, anthropological archaeologists draw upon both cultural and material remains to understand past human societies, including their technologies, social practices, and ideas.
Through the excavation and analysis of ancient Mayan artifacts, Mary would contribute to our understanding of the Mayan culture and its connection to current practices and environmental conditions. Mary's work may also intersect with the study of bioarchaeology, as this field involves interpreting both cultural and biological aspects of past human communities.
