Your teeth are biological archives of ancient human migrations
In short: Every family has a migration story, but your ancestors left a physical record of theirs in their teeth. By analyzing the chemistry of ancient remains, bioarchaeologists can reconstruct centuries of movement, revealing how people traveled, what they ate, and how they adapted to new environments.
Archaeologist Carolyn Freiwald explores how teeth serve as unique biological archives. Unlike many other remains, teeth preserve specific chemical and biological data that allow researchers to trace human movement across vast distances and long periods of time. By studying these 'hidden clues,' scientists can reconstruct the paths taken by diverse groups, from Mayan royalty to rural Appalachian farmers. Her research specifically focuses on movements across Mesoamerica. This work helps reveal how people used their environments to hunt animals and craft tools. She examines these clues to understand the biology and chemistry of both bones and teeth. These records provide a window into the lives of people from Belize to Mississippi.
The methodology combines traditional archaeology—using tools like trowels—with sophisticated chemistry. This dual approach allows researchers to look beyond the surface of bones to understand the nuances of human existence. Freiwald's research specifically examines how people interacted with their environments, including their hunting practices and the tools they crafted, by interpreting the chemical signatures left behind in their dental records. Freiwald earned a doctorate. The University of Wisconsin-Madison granted her a degree in Anthropology. She also earned a B.A. in International Relations and History. Her academic work has appeared in several journals, including Ancient Mesoamerica and the Journal of Archaeological Science. She serves as an associate professor at the University of Mississippi.
This work highlights migration as a universal human experience. According to Freiwald, the essence of humanity involves migration, a phenomenon present within all global societies. By looking at the lives of Belizean buccaneers and Maya kings, her work connects the personal stories of modern 'movers' to a deep, ancestral history of movement that spans centuries. In 2019, she was granted the College of Liberal Arts New Scholar Award. That same year, she traveled to Japan, Canada, and France to share these historical insights. As the granddaughter of German immigrants, she personally identifies as a mover between several regions. Her 2020 talk highlights how these past stories inform our understanding of modern migration.
